Fig. 26 is a plan view of the structure shown in Fig. 25; illustrating a step in the development of such structure into a finished pen nib or writing point element within the scope of my invention.

It will be understood of course that any pen nib or writing point element of metal is of quite ,small area in cross section and, in fact, in all dimensions. In view of this it has been necessary to greatly enlarge and, in some respects, to exaggerate -the size of the pen nib or writing point element forming the subject of my invention, as well as the carrier mounting or support for the same and its details of construction, as illustrated in the accompanying drawings. I do not therefore desire to be limited to any of the dimensions indicated nor any relation incompatible with good fountain pen practice.

In Figure l of the drawings, which shows an elevational View of my improved writing implement, the pen barrel is indicated at 30 and, in this instance, has apen section 3l, from which extends a streamlined and/or tapered carrier mounting or support containing the improved pen nib or writing point element, more particularly pointed Yout hereinafter. It is within the scope of my invention to substitute a pen section of a different type than those usually employed with fountain pens and as shown in order that a complete streamlined and/or tapered effect may be produced, as indicated by the broken lines Figure l. Also, it is within the scope of my invention to associate my improved stream-lined and/or tapered carrier mounting or support at the forward .end of the writing implement and containing a pen nib or writing point element of the character hereinafter set forth with forms of p en barrels which omit the pen section such as indicated at .31. In this connection I have reference to types of writing implements or fountain pens which are provided with ink by means other than the compressible rubber sac usually employed as an ink reservoir.

The barrel 3D may be of any usual type and of any material common in the art. While this barrel ris shown in Figs. 1, 9, et Seq., as provided with a pen section 3l to which the carrier mounting or support is attached-a construction common to fountain pens having a sac reservoir for the reception 0f ink-the pen section may be omitted and the carrier mounting or support such as that indicated at 32, with or without other .connected parts, may be introduced directly into the .end of the pen barrel 30, as indicated in Fig. 1.5. The carrier mounting or support at the forward end of the writing implement may be fitted Ato the pen structure-barrel 3@ or pen section 3I--directly, by a threaded engagement or otherwise, but in Figs. 9, 16 and 18, I have shown the carrier mounting or support 32 associated with a sleeve 35, of a type such as those employed with unit inserts for fountain pens which include .a feed-bar and a pen nib. These unit insert sleeves are usually in threaded engagement with the pen section, or with the end of the barrel, when employed with fountain pens.

lVfy improved pen nib or writing point element is of a peculiarly novel character and one form of the same may be developed in the following manner.

In Fig, 2 I have shown plan and edge views of a strip of pen metal, which may be of any suitable nature or character including stainless steel and whose gauge may be within the range of any of those commonly employed in the manufacture of writing pens or nibs for fountain pens, or of any other gauge that will permit of development in accordance with that part of my invention,

This strip may be cut from a, band of pen metal; stamped from any character of pen metal sheet, or otherwise prepared. In its preparation, usually by a die cutting operation, small protuberances are produced for e, purpose to be described. The strip is indicated at 36, and the lprotuberances are indicated at 31 and 38; a pair of the latter being shown, for a purpose hereinafter set forth.

To the end of a strip of predetermined and desired length I secure, preferably by a suitable welding operation which may be an electric weld, a hard writing point 39, as illustrated in Fig. 3 of any wear material common in the art-and I then grind or otherwise face one side of the same flush with one surface of the strip, as indicated at 39a; producing the structure illustrated in Fig. 4. I then take a pair of strips prepared in the manner set forth and as illustrated in Fig, 4, place them with the flattened point surfaces in juxtaposed relation as illustrated in Fig. 5, with the several protuberances in contact to properly space the strips with respect to each other, and I may then weld the protuberances 3l together; leaving the protuberances 38 in loose contact. The spacing between the strips effected by the presence of the protuberances is designed to be of e, capillary dimension.

After the welding operation securing the strips together, the duplex structure illustrated in Fig. 5 is turned over and the broader dimension may be presented to a saw, indicated by the broken lines, Fig. '7, which saw serves to slit the duplex strip for a predetermined distance, as indicated at All in said view; such slit, which passes between the protuberances 38, being also intended to be of a capillary dimension and of the same width as the spacing defined by the protuberances. A cross sectional view cf the duplex strip taken through the welded protuberances 3l on the line VI-VL Fig. 5, is illustrated in Fig. 6; such View showing the structure to be substantially square. It is within the scope of my invention to round this durplex strip structure, as illustrated in the cross sectional View, Fig. 6a.

Inasmuch as the width of the strip 36 is somewhat greater than its thickness, it may be desirable to taper the end of the same receiving the hardened writing point before application thereof in the manner indicated by the broken lines Fig. 7, or the full-line illustration in Fig. '7a.

It will be understood that prior to the slitting operation, the strips are in proper position with respect to each other-longitudinally as well as transversely-and that after the sawing has been completed as illustrated in Fig. 7, the duplex strip to form the novel pen nib or writing rpoint element will comprise four prongs 36e; each having a portion ef a hardened writing tip 39h.

Before the improved pen nib or writing point element is assembled with the carrier mounting or support to produce the improved writing implement, the forward ends of the same are raised or otherwise operated upon to bring the hardened writing points into contact so as to complete the structure and establish its Vwriting abilities. Inasrnuch as in practice the writing implement will be used with the broader faces of the strips 35 constituting the pen nib or Writing point element in a substantially vertical position, there is full opportunity for the pen nib or writing point element to flex, and its disposal within the carrier mounting or support with its open end permits further movement at this point, assisted by the presence of a space or spaces within the carrier mounting or support for the passage of air and/ or ink.

Upon reference to Fig. 12, which shows an end elevation of the forward portion of the writing implement, it will be observed that the hardened paper-contacting portion of the pen nib or writing point element is slit in two directions; the horizontal slit, indicated at c, representing the separation between the pair of pen metal strips 36 making up the same while the vertical slit, indicated at l2, represents the separation effected by the sawing operation. Except for the smoothing of any rough edges that may be present, no other c-peration is performed with respect to the paper-contacting portion save the raising or other sterp to bring the hardened portions into contact or engagement, as above noted. While, normally, the writing may and probably will be effected by the narrower portions of such end, it is possible to make broad strokes with the sides of the same though, perhaps, not as effectively as with the narrower portions.

It is possible, however, to further shape this paper-contacting portion of the pen nib or writing point element and in Fig. 12ab I have shown one of the forms in which such shaping may be developed and wherein the end of the hardened nib portion, looking toward the same from the front, is shown as substantially oval or eggshaped, This View is unshaded to preserve clearly the distinction between the form of writing portion shown thereby and the form illustrated in Fig. 12. The broader portion, at the top of the illustration Fig. 12a, will produce a line or stroke like either of the narrower portions of the form illustrated in Fig. 12, while the narrower portion at the bottom of such illustration will produce a fine or relatively narrow line; thus providing, in the one point, for two types of writing. This form of the point is slit horizontally and vertically as indicated at a. and b'; such slits corresponding to the slits a and b, respectively, of the point illustrated in Fig. 12. It will be understood, of course that the inclined sides of the point shown in Fig. l2a will not usually be employed in writing operations due to their Obliquity,

In the further carrying out of my invention a pen nib or Writing point which may be made in the manner above set forth is assembled with a carrier mounting or support which may have a stream-lined and/or tapered contour, as indicated at 32. This carrier mounting or support is preferably sectional in character and internally shaped to receive the pen nib or writing point element. I may, in some instances, employ a substantially solid carrier mounting or support with a longitudinal bore or passage into which the pen nib or writing point element may be introduced; preferably from the front.

The carrier mounting or support 32 for the pen nib or writing point element may be made of any suitable plastic common in the arts-particularly the fountain-pen art-thermosetting or thermoplastic; perhaps of other materials in some instances, such as dense wood or other fibrous bodies. It is preferably molded from a suitable and available plastic and while it may be in one piece in some instances, as hereinafter pointed out, it is preferably sectional. While it may be `in several parts, it is more conveniently in two parts and as these are fitted together for cooperative engagement with the pen nib or writing point element disposed between the same, they may be of an identic character as to shape; being designed to t together in exact relationship. While many ways of securing these sections to gether may be employed, they are preferably cemented with a bonding agent unaiected by and unaffecting the ink 'and of a nature that will hermetically seal the joint or joints between the sections but, at the same time, of such character as to permit separation under conditions requiring repair or adjustment of the pen nib or writing point element. In addition to the cementing together of the sections, they may be pinned. It is also within the scope of my invention to effect union of these sections by the agency or heat after the pen nib o1- Writing point element has been properly positioned to function in the operation of writing. It is also within the scope of my invention to lacquer or otherwise coat the carrier mounting or support for the purpose of embellishment or to hide the joint or joints, and it is also within the scope of my invention to enclose the carrier mounting or support within a shell or covering sheath, which may be of a plastic or of metal-a precious metal, for instance.

One form of sectional carrier mounting or support within the scope of my invention is shown in elevation and partly in section in Fig. 9, and in cross section in Figs. l and 1l. In this instance, the sections oi the carrier mounting or support are indicated at 32a and 32h, and the line of original division between the same is indicated at s, Figs. l0 and 1l. In this instance the carrier sections have a flange di at one edge which seats in a recess ila at the opposite edge of the respective sections. This arrangement, though not essential and may be omitted, is of value in the operation of connecting a, pair of sections with the contained pen nib or Writing point element to complete the development of that much of the writing implement. Internally the several sections will be provided with capillary spaces for the flow of air and/or ink and for the storage of excess ink and for drainage purposes; all as more or less necessary for proper operation of the writing implement.

In the structure shown in Fig. 9 a series of transverse partitions or combs, 52, provide capillary spaces il between the same;y such spaces serving to receive any excess or surplus ink and avoid all danger of leakage in the operation of writing, or otherwise. In addition to these cross capillary spaces lit, it may be desirable to provide the carrier mounting or support with longitudinal drainage fissures, which are indicated at fili, Figs. 1l and l5; such fissures permittinfy air to pass to the capillary spaces i3 and assisting the return or" ink to the reservoir when the act of writing is ended and the Writing implement is laid aside or carried in the pocket of the user. It seems unnecessary to note that these cross capillary spaces as well as the longitudinal fissures provide for the storage of ink which may be lifted to the carrier mounting or support by elevations in temperature; Whether due to the hand of the user; transport in his pocket or otherwise carried, or for any other reason. At the same time, the presence of these capillaries in the carrier mounting or support insures the presence of ink-the desired wetting of the pen nib or writing point-when commencing the act of Writing.

In addition to the cross passages 133 and the longitudinal iissures M, the sections of the carrier mounting or support are provided with other capillaries for cooperation with the pen nib or Writing point element carried by the same; one set of such capillaries being indicated at 35, and the other set at E5, both extending longitudinally of the carrier mounting or support. The forward end of the carrier mounting or support may be provided with openings ril for the admission of air to replace the ink drawn from the reservoir of the writing element and passing to the papercontacting end of the pen nib or writing point element, while the forward end of the carrier mounting or support has an opening e3 for the passage of the pen nib or writing point element of suicient size to permit a certain amount of flexing of the pen nib or writing point element in the act of writing. It may be unnecessary, in view of this opening d3, which will to a certain extent at least permit the entrance of air to take the place of the displaced ink, to provide the special openings lil.

In assembling the pen nib or writing point element with the carrier mounting or support, the rear end of the former is laid in the recess 5Q- either one-at the stem end of one oi the sec-- tions as indicated in Figs. 9 and 10; the substantially square shank portion of such pen nib or writing point element snugly fitting the recesses of the sections as indicated more particularly in Fig. l0. In this connection it may be noted that it is within the scope of my invention to employ a writing point element or pen nib having a rounded stem or shank portion, as illustrated in Fig. Gd, and to provide the stem portions of the respective sections of the carrier mounting or support with rounded recesses to receive the same.

Above and below the pen nib or writing point element are the longitudinal capillaries or spaces 35, one of which may function fior the passage of ink and the other for the passage of air to the reservoir as the ink is used. These capillaries extend from end to end of the carrier mounting or support. In addition there may be capillary spaces l5 disposed opposite or cutting through the combs or cross partitions i2 and extending to the openings il adjacent the forward end of the carrier mounting or support, or all of these longitudinal capillaries may extend to the opening i8 at the forward end of the same.

In the form of carrier mounting or support shown in Fig. 9, the sections olf the same have reduced rear ends forming a stem E2G and this stem, in this instance, is associated with a sleeve 35, such as those employed with the so-called unit inserts employed with some forms of fountain-pens. This stem may be permanently attached to the sleeve or be in lfrictional engagement therewith, and the said sleeve may be in threaded engagement with the pen section 3|, as indicated in Fig. 9, or in frictional engagement therewith. It is within the scope of my invention to connect this sleeve directly with the barrel Sil of the writing implement in those instances where a pen section is omitted. The sleeve 35 may be of a suitable metal, or of any of the synthetic or other plastics commonly employed in the arts-particularly the fountainpen art.

'Ihe shank portion of the pen nib' or writing point element may be clamped in the recesses 5B in the stem portion oi the carrier mounting or support sections and as it should occupy a xed position with respect to the same so as to avoid all danger of being displaced longitudinally suitable manner.

during a writing operation, it may be pinned in place. In lieu of this, oppositely disposed protuberances may be struck up from the pen metal employed in its construction and arranged for disposal at the shank portion of the pen nib or Writing point element so as to be embedded in the body of the carrier mounting or support in the assembly thereof; an arrangement readily available and particularly if a heat treatment is involved inthe assembly of the sections of the carrier mounting or support.

In Fig. 13 I have shown a fragmentary view, partly broken awayron the line of original separation between the sections of the carrier mounting or support; showing also the flange 4| and the recess 4|a, of the section 32h, which cooperate with similar portions of the section 32a. Fig. 14 is an enlarged view, fragmentary in character, of the forward end of the structure illustrated in Fig. 9, to bring out clearly the touching protuberances 38 of the strips 36, and the cross partitions 42 of the internal comb providing the capillary spaces 43.

Fig. 15 is a view somewhat similar to Fig. 9, but the section is on the line XXI-XV, Fig. 11, in the plane of a pair of the longitudinal fissures 44, and it discloses a modification within the scope of my invention. In this arrangement, the stem 32 of the carrier mounting or support is shown as threaded at 32d for threaded engagement with the pen section 3|, instead of employing a sleeve such as indicated at 35, Fig. 9. It is also within the scopeY of my invention to connect a carrier mounting or supportof this type directly with the barrel of the Writing implement without the use of a pen section. In this View the roots of the capillary spaces 43 are illustrated as being rounded, as indicated at 43a. Y

In Figs. 16 and 17 I have shown a further modification of the carrier mounting or support, wherein the internally arranged transverse capillary spaces are shown as inclined from the outer surface of the same toward the. central bore receiving the pen nib or writing point element to facilitate drainage of ink when the writing implement is not in use. In this view the pen nib or writing point element is shown by dotted lines. Fig. 17 is a cross sectional view on the line XVII-XVII, Fig. 16, and in this view the pen nib or writing point element is shown as occupying its proper position with respect to the recesses 50 of the sections making up the carrier mounting or support.

In Figs. 18 and 19 I have shown a carrier mounting or support in the for-m of a single piece, indicated at |32. 'Ihis will have a longitudinal bore or passage `for the reception of the pen nib or writing point element, which may be introduced from the front end of the same. For the sake of clarity, the pen nib or Writing point element is omitted from Fig. 18. A series of longitudinal fissures |44-in the present instance four-are cut through the forward portion of this member; an operation that may be effected by a saw or other suitable cutting instrument or these fissures may be developed during the molding operation. `If saWn or otherwise cut, the original cuts may extend substantially to the line and the balance ofthe fissures, which may slope toward the central bore, may b'e breached or cut by a suitable tool and in any As the fissures |44 cut through the surface of the member |32, it is substantially necessary to enclose the same in a sheath or cover, which is indicated at This sheath or cover, which shouRl be relatively thin, may be made from a plastic material or from metalone of the precious metals, for instance. This sheath or cover will be turned in behind the shoulder of the carrier mounting or support, as indicated at 52. Other ways of securing this sheath or cover in place may be adopted and it is Within the scope of my invention to thread the rear end of the sheath or cover and to thread the rear portion of the carrier mounting or support to engage the same. Any manner of insuring that this sheath or cover shall hermetically seal the fissures |44 cut through the body of the single-piece carrier mounting or support, is Within the scope of my invention. It is also within the scope of my invention to seal the outer openings of these fissures before the sheath or cover is applied. In Fig. 19, which is a cross section taken on the line XIX-XIX, Fig. 18, the pen nib or writing point element is shown in its proper position with res-peet to the central bore or passage of the carrier mounting or support. While I have shown four longitudinal fissures |44, it is within the scope of my invention to employ a greater or a lesser number in order to provide sufficient storage space and/or drainage facilities for the ink.

In other respects, the forms of carrier mounting or supports illustrated in Figs. 16, 17, 18 and 19 will be like the form illustrated in Fig. 9 as to the longitudinal capillary spaces adjacent the pen nib or writing point element and the air openings and, with respect to the structure shown in Figs. 16 and 17, transverse partitions or .combs and transverse capillary spaces. These forms of the carrier mounting or support are shown as assom ciated with a sleeve 35 which may be in threaded engagement with the pen section, as indicated, cr

with the barrel of the Writing implement.

Other forms of pen nibs or writing point elements are within the scope of my invention and in lieu of the form of construction illustrated in Figs. 2 to 8, inclusive, I may provide a'form of pen nib or Writing point element of the type and in the manner illustrated in Figs. 20 to 23, inclusive.

In Figs. 2O and 21 I have illustrated at |33 a strip of pen metal of suitable gauge, which may be cut or stamped from metal stock in the usual manner and, while being blanked or otherwise, is provided with pairs of protuberances |38 disposed adjacent each end; the latterl being cut squarely at right angles to the longitudinalv aXis of the strip. This strip is intended to be just twice the length of the strips 36 shown in Figs. 2, 3, et seq.A At each end of the strip |36 I secure, as by welding or otherwise, a piece of hardened material-metal or other body-as indicated at |39 to form the paper-contacting portion of the pen nib or writing point element. These hard portions are faced off at |39a in a manner similar to the facing imparted to the hardened material as illustrated in Fig. 4, and then the elongated strip |38 is bent to form the structure illustrated in Fig. 22, with the spacing between the plies of the same of a capillary dimension and with the protuberances |38 in loose engagement. To provide the additional capillary space or spaces, the folded strip shown in Fig. 22 is turned over at right angles to such position and saw slit as indicated at |46, Fig. 23,` in the same manner as illustrated in Fig. '7.

The form of pen nib or writing point element Y illustrated in Figs. 22 and 23 may 'be employed in the same manner as that illustrated in Fig. 9,

topierce the'bend in order to facilitate passage of ink and/or air to and from the reservoir of the writing implement. This piercing may be in the form of a single aperture 55, which may be drilled as indicated in Fig. 22a., or slits may be cut through the bend in any suitable manner, as indicated at 56, Fig. 221. The hardened tip of this form of the pen nib or writing point element may be treated in the same manner as the tips illustrated in Figs. 12 and 12a.

Other forms of writing point elements are within the scope of my invention, and in Figs. 24, 24a and 24h I have shown a form of pen nib or writing point element made from pen metal stock such as that disclosed in several prior patents of Leon Hehl Ashmore, Nos. 2,037,699; 2,159,002; 2,159,003 and 2,228,250. This metal stock is provided with a thickened edge, indicated at 60, and two strips of the same, indicated at 235 and which may have protuberances 23'! and 232 struck up from the same may be placed in juxtaposed relationship, and the protuberances 23? welded together; those indicated at 238 being unconnected as in the other forms of pen nibs or writing point elements hereinabove described. These protuberances space the strips for the desired capillary action in use. Fig. 24@ shows an end View of the structure illustrated in Fig. 24, and the dotted lines represent the application of a saw slit at right angles to the broad faces of these strips to form the additional capillary spacing. Fig. 24b shows the end of the structure developed into a writing tip or paper-contacting portion. The thickened edge projections 60 may be rounded as indicated at 50a and brought together by a raising or other operation, as indicated; the slits between the parts of Said tip being indicated at a2 and b2. This form of tip will provide a plurality of writing points.

In Figs. 25, 25e, 25b and 26 I have shown still another form of pen nib or writing point element within the scope of my invention. In this structure I may employ a pair of pen metal strips 335, with protuberances 331 and 333 produced in a manner similar to that hereinbefore described;

the protuberances 331 being welded together and i the protuberances 338 being unconnected. In this instance, I make use of one strip only in the formation of the writing tip end of the pen nib or writing point; the other strip being tapered oi at its forward end and underlying the upper strip short of the end to which the hardened tip material, 330, is applied-a single element. If desired, this upper strip carrying the hard tip may have a tapered end, of the character illustrated in Fig. 26, following the form illustrated in Fig. 7a, and after the welding operation to secure such hard tip in place, this strip may be slit as indicated by the dotted lines at 3F50, Figs. 25a and 26. The finished paper-contacting end of the pen nib or writing point element is illustrated in Fig. 25b and this end, after the raising or other operation imparted thereto to bring the portions of the hard tip material together will have a single vertical slit, indicated at b3; providing two paper contacting portions. This hardened point may be developed into a writing tip ofthe character illustra-ted in Fig. 12a, but without the horizontal slit.

While I have referred to the welding of the protuberances at the shank portion of the pen nib or writing point element (3l, I3?, 231 or 33?) it is within the scope of my invention to so connect the metal strips making up these pen nibs or writing point elements with the sections of the carrier mounting or support :as to independently embed or otherwise secure the same 12 therein in proper relative position so `that when these sections are assembled and fastened together, the several protuberances will be in registry to assure the desired capillary spacing between the strips. Such arrangement, of course, will bring the writing tip ends of the respective strips making up the pen nib or writing point element in exact registry.

It will be understood that all forms of the pen nib or writing point element illustrated and described may be employed with any of the forms of carrier mountings or supports illustrated and described. It will also be understood that all of the forms of the pen nib or writing point element illustrated and described may have the shank and/or stem portion rounded in a manner similar to that illustrated in Fig. 6a.

It will be further understood that while I have shown and described the type of carrier mounting or support illustrated in Figs. 18 and 19 as having a sheath or cover in order that the through cuts IM defining the iissures may be Ihermetically sealed, it is within theY scope of my invention to enclose any or all of the forms of carrier mountings or support described and illustrated in the drawings in sheaths or covers which, in addition to any functional purpose, will serve to embellish or ornament the forward portion of the writing implement.

While I desire to employ a carrier mounting or support having a stream-lined and/or tapered contour, the dimens-ions of the same may difer from anything illustrated in the drawings or herein described; that is to say, it may be narrower or thicker-depending upon the diameter or bulk of the Writing implement-and it may be relatively longer or shorter as conditions or circumstances, particularly those pertaining to design, may warrant. While the carrier mounting -or support of the preferred type is sectional, the one-piece type illustrated in Figs. 18 and 1-9 is entirely practical and it is also within the scope of my invention to annularly groove this type of structure; such grooves to be of capillary dimensions yand in communication with the longitudinal fissures lll-4 and enclosed by the sheath or cover.

The dimensions of the several Acapillary spaces may be altered w-ithout departing from my invention and it will be Yclearly understood that, in view of the small 'dimensions of the parts inn volved, the several views of the drawings are greatly enlarged andV more or less exaggerated in order to clearly define the subject-matter of my invention.

It will also be understood that while I prefer to employ the novel form of pen 'nib or writing point element illustrated in the Yaccompanying drawings and described herein with the `novel form `of `carrier mounting or support also lshown and described, that I do not wish to be limited to the same since other forms of pen nibs or writing point elements may be employed without material change in the disposal of the same within the novel carrier mounting or support and/or in -relation to the several capillary spaces therein. It is within the scope of my invention to omit the special yair inlets 41 -at the vforward end of the carrier mounting or support and depend upon the opening 48 at the end of the same through which vthe 'writing tip extends forV the inlet of air as ink is displaced from the reservoir of the writing implement. vThis opening 4'8 is shown as substantiallyrectangular in view of the rectangular Vshape of the pen nib or writing point element. It is Within the scope of my invention to make this opening round especially if the shank or stem of the pen nib or writing point element is rounded .as indicated in Fig. 6e, or when a pen nib or writing point element of the character illustrated in Figs. 25 and 26 is employed.

The longitudinal drainage fissures fili, illustrated in Fig. 11 are shown as angularly disposed with respect to the plane of original separation between the sections. It is within the scope of my invention to arrange one pair of these fissures in the plane of original separation of the sections and to provide the other pair at right angles thereto or in any other convenient position that will facilitate their production in a molding operation.

While I have illustrated and have described with some particularity a number of ways in which my invention may be carried into eiect, this disclosure is for illustrative` purposes only and not as a limitation inasmuch as many modications may be made embodying the spirit of my invention; all of which is deemed to be within the scope of the appended claims.
