Application filed June 10, 1914 Serial No. 844,210.

To all whom it may concern:

Be it known that I, RUssELL T. WING, a citizen of the United States, residing at St. Cloud, in the State of Minnesota, have invented certain new and useful Improvements in Fountain-. Pens, of which the following is aspecifiuseful improvements in fountain pens having for its object among others to provide a simple, durable, efilcient and inexpensive pen in which the pen point is so constructed essential features stituting what may as to be practically proof against bending or breaking in ordinary accidents, such as catching in writing or from such shocks as it would receive inaccidentally dropping it to'the floor,

of a perfect flowing fountain pen of the quill type.

A'furtherfobject is to provide means conbe termed an internal governor constructed to take care of the overflow within the head of-the pen. This is attained. by providing a capillary cavity or holder, so formed that the narrow end of the cavity will be n communication with the ink in the well,

the forward and larger end being left open ,to the air, the cavity being tapered, all for a purpose which will hereinafter appear. I dispose the spring portion of the nibs near I the rear of the point and back in the head of the pen, the forward portion of the point having its nibs made stiff and to withstand shocks, and finally tapered to a suitable writing tip, the nibs' being restricted in their separation or parting mpveznent by the surrounding head. piece.

Other objects and'advantagess of the invention' will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.-.

The invention, clearly illustrated in I the accompanying with the numerals of reference marked thereon, form a part of this specification, and in which-- i Figure 1 is an enlarged longitudinalsece point-end portion.

Like numerals of reference indicate like parts throughout the difl'erent views.

Referringto the drawings, 1 designates a tubular holder of any ,suitable material, such as hard or vulcanized servoir for end with internal screw threads, as at 2, for the detachable reception of the screw-threaded plug 3 which, in'turn, is ezrteriorly thre'aded as at 4, for the detachable engagement of the cap 5 in the usual manner. The holder 1 and the plug 3 may be all in onepiece, and for this reason the plug and holder throughout the specification will be termed the holder. The forward end of this holder Ivlvhich shows a screw plug will betermed the ead.

My invention resides inthe construction of the pen itself, which is made of suitable metal and comprises the tubular portion 6, the nibs- 15 and the spring portion 7 as shown. The body portion 10 (called the inclosed portion of the nibs) is longitudinally slitted, as seen at 14, from thetubular portion 6 to the end or tip. These nibs are made stifi' and strong toward the forward portion. At the rear, adjacent to the tubular The said upper surface is disposed on a I plane oblique to the longitudinal axis of-the tubular portion 6 and in a plane s'pbstantially parallel with the body portion 10, forming thereby a shoulder 19 that is preferably rearward]. inclined relatively to the points, and provides 1n conjunction with t e upper surface of the body .portion and the adjacent wall of the plug -3 a chamber 13.; At this point itself serves to take up the ink which might collect on the rapid closing of the nibs.

When the point is placed in the head as shown in Fig. 1, two cavities are formed by reason of the shaping of the inclosed portions of the nibs. The upper side of the inclosed portion of the nibs as well as'the lower side, are inclined as at 11 and 8, form ing the cavity 13 on the upper side and the passage 12 on the lower side. The passage 12 communicates directly with the tubular portion, placing the ink in the well practically in direct contact with the nibs. The

under and lower end of the inclosed portion of the nibs practically rests on the wall of the head as at 9.

By making the pen with the large opening for the ink where the ink flows from the well to the point, the nibs are ractically directly in contact with the ink in the well or reservoir 1. The air gains access to the reservoir or well by working under the nibs in writing. As the sides of the inclosed portion of the body 10 at 17 17 touch or nearly touch the inner walls of the heador plug, they form the cavity 13 above described on the upper side of the pen to the rear of the nibs; the ink from the reservoir or well is retarded from vpassing into this cavity, by capillary attraction, except slightly into its narrower end. It is to be understood that the size of the hole in the tubular portion may be small or large, according to the quality of the pen. By havmg the point directly in contact with the ink in the well, the ink is always at the point and does not depend upon the capillary attraction of any feed arrangementfor the flow of the ink.

In use, the chamber 13 takes care of the, ink flow entirely. An even flow is obtained at all times, since a small amount of liquid in a tapering cavity will always seek the narrower end, and as the narrower end is at 18, see-Fig. 1, then if the ink' artially filled the chamber 13 n writing t e ink would not remain at 19, the larger end of the tapering chamber, but would flow back to near the point 18 as long as used until air rises inthe well, passing around the nibs, and more ink comes down, maintaining a constant level of ink 'in the governing cavity 13 as long as the pen is used. It 1s to be noted that the forward end of the chamber 13 is left open to the air which is done to prevent a film of ink from collecting at the point 19, which might happen if this were not done, and to allow air to play freely back and forth in the chamber 13 as the ink pressure in the well may vary, forcing the ink into the chamber 13 at different levels. film of ink at this point 19 would cause ink to be expelled instead of air, from the chamber 13, and thus result in a direct overflow of ink on the tip of the pen if there were anyexpansion of the air in the reservoir 1.

From the above it will be seen that I have devised a novel form of fountain pen caable of manufacture at small cost, embodymg but few parts and those readily assembled or separated when desired, and while the structural embodiment of the invention as hereinbefore disclosed is what 1 at the present time consider preferable, it is evident that the same is subject to changes,

variations and modifications in details, proportion of parts, etc., and 1 therefore, do

not intend to restrict myself to the exactconstruction herein disclosed, but reserve the right'to make such changes, variations and modifications as come properly within the scope of the protection prayed.

Briefly described, I have provided a fountain pen having a suitable type of reservoir 1 with a pen section 3 at one end thereof, inwhich pen section there is arranged a combined pen and feeder which has a tubular mouth portion 6 opening into the reservoir and from which extends a pair of parallel nib shanks or necks 1717 having a generally inclined direction from the upper rear portion of the mouth down to the lower front end of the pen section on which the ends of the shanks 17 are provided with.

nibs 1515 disposed wholly beyond the end of the pen section. Preferably the exterior contour of the neck sections 17-17 when these are in relatively closed position, as shown in Fig. 3, is such as to form above the top surface of the shank a chamber or pocket 13 which tapers gently from the outer portion of the pen section to the rear,

portion above the' flexible and flattened parts '7 of theshanks 17, thus allowing the ink which'passes between the split line 14 of the shanks to pass under capillary action into the rear portion of the chamber 13 in which the body of ink will collect and be retained during the writing action of the pen nibs.

The operation of this pen structure-and the formations of the respective parts may be explained as follows: When the necks 10 swing down to position :shown in Fig. 1 there is formed above the top thereof an inwardly contracting space in which ink is drawn and held by capillary attraction. When the nibs 15' are applied to a surface for writing the necks 1O spread apart and upward and ink then flows from the mouth I 6 into the kerf and along the nibs to the of the necks theink will advance and recede in the space 13 always receding toward the smaller end as the nib necks approach and the space 13 enlarges,

I have shown in this instance the mouth piece 6, the nib necks (or feeders) l0 and the nibs 15 as being integrally formed.

What I claim as new is 1. In a fountain pen, a reservoir having a pen section and a combined pen and feed having nibs projecting wholly beyond the pen section, the feed comprising a mouth end and a split shank mounted 1n the section and communicating with the reservoir and forming resilient portions connecting the mouth and the pen nibs and lying in a' generally inclined position within the pen section to form an outwardly convergent lower ink space and an upper outwardly flaring ink space, the split shank being movable toward and limited in movement by the interior surface ofthe pen sect-ion.

2. In a fountain pen, a reservoir and a gen section and a combined pen and feed aving a mouth at its inner end opening into the reservoir resilient feed sections extending from the mouth inclosed by the pen section, and nibs, on the ends of the feed sections', projecting beyond the pen section, the feed sections forming an inwardly contracting ink space at"the1r upper surfaces below the pen section.

In testimony whereof I hereunto afix my signature in presence off two witnesses,

- iaUssELL T. WING.
