STRIP-SERVING APPARATUS.

Be it known that I, EARL L. BROWNSON, a citizen of the United States, residing at Allston, in the county of Suffolk and State of Massachusetts, have invented an Improve,

ment in Strip-Serving Apparatus, of which the following description, in connection with the accompanyin drawings, is a specification, like numera s on the drawings representing like parts.

This invention relates to devices for supplying strips of paper or the like for wrapping or binding purposes orfor use as a label,

and 1s a division of my copending application, Serial No. 370,194.

The invention has particular reference to that type of apparatus employing a support for a coil or roll of aper strip previously lgl'ummed upon one sig aving means for moistening the gummed side of the strip as the latter is withdrawn from its'coil. It is'apparent, however, that .an ungummed strip of paper maybe emloyed, in which case the moistening device or the strip suitably positioned with respect thereto would contain an adhesive instead of water.

In order that the principles of my invention may be readily understood, I have disclosed a single type or embodiment thereof in the accompanying drawing, wherein- Figure 1 is a view, partial y in side elevation and vertical section, of a portion of a strip serving-device illustrating one embodiment of my invention; Fig. 2 is a vertical sectional view showing the relation of the moistener and the strip presserdurin the serving and severing operations; and *ig. 3 is a side elevation of a form of severing blade that may be employed in the practice of my invention.

The paper or other material, preferably in the form of a coil or roll and referably pre" viously gummed upon one si e, is indicated at 1, it being mounted and suitably tensioned in any suitable manner, as, for example,

within a casing 2 which in this embodiment of my invention. also receives between its upright walls the tank or reservoir 3, which may be withdrawn through the open front face of the casing. Mounted within the tank or reservoir 3 many suitable moisture conveying device, herein represented as a roll 4 having an absorbent covering 5. The strip may be Specification of Letters Patent.

manner. I have in this embodiment of my invention represented means for feeding the rolls 6, 7, mounted in the casing and between which the strip is delivered, the roll 6 being provided with a pinion 8 loose upon' the spindle thereof, but adapted to be clutched to said roll by a pivoted pawl 9 normally pressed by a s ring 10 into engagement with the teeth of t e pinion. Meshing with the pinion 8 is a segmental gear 11 ivoted upon the spindle 12 in the casing an having connected thereto and. exterior to the casing an operating handle 13. A spring 14 coiled about the spindle and connected to the handle 13 tends normally to return the handle to the upright osition indicated, the pawl 9 permitting t e rearward vrotation of the pinlion 16 without similar movement of the rol 6.

Preferably I provide means to permit the feeding of different lengths of strip. For that pur ose, I have here shown the casing as provi ed with a series of holes 15, any one of which may receive a pin which when positioned limits the forward or feeding movel ment of the handle 13. A pin 16 limits the return or non feeding movement of the handle. Between the feeding rolls and the moistener, I may provide a guide, here shown as plates 17, between which the strip is fed toward the moistener.

My invention comprehends-means to hold the strip in moisture receiving relation'to the the upper face of the moistener. Such means in this type of myinvention is shown as a roller 18 closely adjacent the moistener and mounted to move vertically in slots 19 in the casing, said roller being held by springs 19 in the described relation to the strip and moistener, but any other suitable device may be employed so long as it is arranged to hold the strip down onto the upper surface, preferably of limited extent,'of the moistener at all times; that is, during the periods of rest as well as during the serving and the severing operations, so that the strip is never normally free from the moistener.

After the desired length of strip has been suitably served, the free end is grasped by the o erator and is led forward the desired lengt and is then deflected to one side, heredelivered to the moistener in any suitable,

moistener, i. e. to hold the strip down onto' strip thereto and herein comprising feeding in upward, against the edge of a blade or knife 20 suita ly mounted in the casing and fixed; that is to say, requiring deflection of the strip to effect the cutting or severing of the strip. The-knife is here shown in advance andabove the moistener, and thu s is spaced from the service path of the strip so as to require deflection of the strip for severing. The free, protruding end after the severing action sprlngs down from the blade and stands projecting into space with its leading edge free from the blade and the moistener, so as to be readily engaged by the operator when the device is to be next used Although I herein show the severing blade in"front of the moistener, and base such disclosure upon the following statementiin my parent application, ,Ser. No. 370,194: In the type of the invention shown it will be observed that the severing mechanism iadocated in the rear of the moistener, While I am not to be limited to such location, I find this construction preferably in certain types of the invention yet, I do not in this present application, claim specifically the severing blade as positioned in front of the moiscasional sealing of packages (meaning by 00- tener, as such specific structure is the subject matter of a separate application.

The presser is positioned slightly in advance of the moistening point, so as to cause the strip to be deflected at all times down ward from the highest point of the moistener and between the strip support and the presser, thu's insurin eflective contact with the latter. A shleld 21 in advance of the moistening point may be employed, if desired, to prevent the strip end from following down around the moistening roll.

Devices of this general character are quite commonly used in stores and the like for occasional use, such use as is not constant and where the device is permitted to stand for considerable intervals of time in disuse), and they are also employed commonly-in establishments where the use is substantially constant, one length after another being drawn from the machine and severed, as, for example, in the sealing or securing of wrappers about packages of paper in paper mills where the devices are in continual use throughout the day with few, if any, substantial intervals of disuse intervening.

In devices of the general charactersuch as first above mentioned, it has been considered desirable to maintain the free end of the paper roll or coil free from contact with the moistener during the intervals when the device is not in use, in order that the coating of adhesive upon that side of the pa er next to the moistener should not be impa1red-or lost bv continued contact with the moistener, and also to prevent the permeation of the strip itself by the moisture, which would weaken it and render it liable to breakage when next eiaeia spring actuated or equivalent lifteror means for normally lifting the strip from contact with the moistener, the construction and arrangement being such that when the strip is seized and led forward for use, the spring lifter or means will .yield to permit the strip to be first drawn down upon the moistener, whereby in the further travel of the strip its adhesive surface will be moistened by contact with said moistener. An objection'to a machine of this type when in constant use has been that the movement or travel of the strip necessary to draw it forward and downward into contact with the moistener and which precedes the effective moistening of the strip involves a waste of time and also of strip length, which, when considered alone or when added to the usual dried, length of strip which was left from the previous use projecting beyond the moistener, has involved such waste as to make it undesirable to use in such manner.

For the second of the above mentioned uses, namely, where the device is employed without substantial interruption, there is not sufficient interval between the use of one strip and the next for the protruding end left upon the machine and moistened by the preceding draft upon the strip to become dried, one use following another in rapid succession, and I have found that when so continuously used, it is unnecessary to remove the strip leave the'strip end in position for ready seizure for guidance and draft, and this is best accomplished by leaving the strip end projecting into space and free from any adj acent surface which would either interfere with ready seizure of the strip end, or whic by contact with the moistened adhesive thereon would tend to remove any of the adhesive either during the short intervals of disuse or when the strip is drawn upon for use. I have therefore in the machine here illustrated provided means, as the presser 18 located somewhat forward of the median line of the moistener and so as to cause the strip to lead down over the moistener somewhat from the highest point of the latter before it leaves the same, to maintain a most effective, constant and normal contact of the adhesive face of the strip with the moistener.

The severing device or cutter; I have arranged at one side of the normal service path of said strip, herein above the same, so as to I be entirely free and clear of the strip and leave the projecting end of the latter standprojecting position for seizure. The dis-5 tance of the severing device above the service path of the strip will, of course, determine the length of the end which projects forward for seizure and ma be adjusted or varied to suit the individua preference,

My invention therefore provides a machine especially adapted for frequent or constant use. It is clear that there is absolutely no loss either of time or strip in the use of e machine herein shown, for the projecting end-of the, strip is already moistened, and each increment of forward draft upon the strip is effective for moistening a corresponding additional length of the strip, which is not the case where the lifter requires first to be depressed by draft upon the strip before the latter is brought into effective engagement with the moistenerrand furthermore in the machine here shown the projecting end of the strip is not pressed upon or drawn into a contact with any metallic or other surface which would tend to remove any of the moistened adhesive or to cause the strip to adhere thereto.

My invention therefore provides a machine especially ada ted for substantiall constant tween the fingers of the other hair to guide,

use and whic by eliminating a waste of time and material possesses many advantages not heretofore found in machines in this art'so far as known to me.

In operating the machine, it is customary for the o erative either to start the feed of the strip y means of the handle 13 engaged by one hand and seizing the stri end beor lay it u on a package or'article to be sealed, finis ing the draft wholly by drawing upon the strip end, or conjointly by so drawmg upon it and continuing the movement b the handle, or by the handle alone, althoug where no definite length is required it is usually found more convenient to draw the strip by and between the fingers which direct it, so that my invention is not limited scriptive sense and not for purposes of 1imi-.

tation, the scope of the invention being set forth in thefol owing claims. a
