STRIP SERVING DEVICE. APPLICATION FILED 11017.16, 1910.

Patented May 9, 1911.

UNITED STATES PATENT OFFICE GEORGE R. WYMAN, OF EAST WALPbLE, MASSACHUSETTS, ASSIGNOR TO CHARLES S. BIRD, OF EAST WALPOLE, MASSACHUSETTS.

STRIP-SERVING DEVICE.

To all whom it may concern:

Be it known that I, GEORGE R. WYMAN, of East Walpole, in the county of Norfolk and State of Massachusetts, haveinvented a new and useful Strip-ServingDevice, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

-This invention has reference to improvements in devices whereby the supplying of material in strip form is facilitated and particularly to that class of such devices by means of which material in strip form and having a gummed surface may be supplied with its gummed side moistened whereby said adhesive strip is adapted to be usedfor binding the wrappers of packages or for any other purpose.

One ob ect of this invention is to construct a machine or device of this nature having a support for a roll or coil of material, usually paper, which has a gummed side, previously dried, and having means for moistening said gum, to render the same adhesive, as said material is drawn from the machine, and havin means to so displace the end of the matenal at or prior to the commencement of the operation that said end may be readily grasped by the operator.

- Another object of this invention is to so construct a device or apparatus of this character and having severing means, located at a distance from the moistening device, against which the gummed material, after receiving moisture, may be drawnto sever said material, that said severing means may be moved toward the nloistening device to displace or deflect the end portion of said material toward or in contact with said moistenmg means, and to move the severing device out of obstructive relation with the end of said material.

Otherobjects of the invention willappear from the following description.

'the severing device, the en Patented May 9,1911.

Application filed November 16, 1910. Serial No. 592,696.

improved strip serving device, parts of the same being broken away. Fig. 2, represents a plan view of the moistening device and the strip severing means with their related parts.

Similar numbers of reference designate corresponding parts throughout.

Strip serving machines having meansfor supporting a roll or coil of material, usually paper, gummed on one side and dried, and provided with means for moistemng the um as the strip is drawn out, are well llnown and various means have been-emplo ed to sever the moistened strip after a suflibient length has been drawn out for use, most of these machines have been particularly adapted for use with stri s of thin paper having comparatively litt e stability so that, after moistening, the paper became limp and where the paper 'assed beneath of the .strip would sometimes drop to a position where it could be taken hold of by the fingers and drawn outward. -When however paper of any considerable thickness, is used in such machine it is found that the cut end of the paper remainsso close to the severing device that it is difiicult to rasp the same without danger of cutting'the fingers by bringing 'them againstthe severing device and, while this'invention is not restricted in its use to paper .or material of any particular thickness, one of theobjects of my invention is to provide a machine. of this character which is also desirable thatthe strip, when released should not be retracted by the reaction of its roll or coil and the machine herein described accomplishes this object by the use of a ten s1on device.

As shown in the drawings, in its prefel red form, 5 indicates a base having the container or case 6, 1n WhlCll the roll or coil A of pa er or other material is rotatable, and havm the mouth '7 throu h which the strip of sue material A may e drawn. This strip A has been gummed on one side, the under side downward thereon by the blade 19 may now be readilybar 11, having a curved upper surfacew mounted in container as shown in Fig. 1,

cooperates with the under surface of the cross bar 12, having sleeves 13, 13 which fit loosely on said posts 10, 10 and are'forced thumb nuts 14, 14: screwed on to said posts. From the sleeves 13, 13 extend the arms 15, 15 having the studs 16,16 and, at the ends, bearings'in which is journaled the shaft 17 carrying the arms 18, 18 connected at their forward ends b the severing blade 19, having a serrated e ge, and at theirrear ends by the rod 20 which is connected with the studs 16, 16 of the arms 15, 15 by the retraction springs 21, 21 which tend'constantly to hold the arms 18, 18 and blade 19, in the position shown in full lines in Fig. 1. The arms 18, 18 are longer than the distance between the shaft 17 and the periphery of the moistening roll 9 so that when t e free ends of said arms 18, 18 are swung toward the parts 10, 10 the blade 19-will swing below the top of said roll 9. 7

A roll or coil of material in strip form and of any suitable 6 and the end of such strip is led through the mouth 7 and then between the tension bar 11 and the cross bar 12, Over the moistening device 9 and beneath the edge of the severing device or cutter 19. When, as is usually the case, the under surface of the strip A, that surface which contacts with the moi'stening device 9, is supplied with gum previously dried, water is supplied to the reservoir 8. When an ungummed strip is to be employed the reservoir 8 is supplied with any suitable fluid adhesive.

In the use of this machine, the operative places his'thumb or finger against the blade 19 or against one of the arms 18 and presses inward, toward the moistening device, whereupon the edge of said blade 19- moves against the upper surface of strip A and deflects this end portion of said strip downward, as shown in dotted lines in Fig. l and brings an additional portion of such strip in contact with the surface of the moisten ing device. which now extends beyond the edge of the grasped and drawn outward to draw a length of the said strip A from its coil and bring the under ganized means thickness is rotatably I That end portion of the strip A surface of said strip in contact with the surface of the moistening device 9 whereby the gum on said surface is moistened is drawn outward the blade 19 and its arms 18,18 follow the movement of the ope'ratives fingers outward. under the action of springs 21, 21. After a sufiicient length of the strip has been drawn out the operative drawsthe strip upward, against the edge of blade 19, and then sharply to one side to sever the strip by drawing the same sidewise against the serrated edge of said blade.

It is to be noticed that the tension or bar 11 prevents the retractive movement of the strip A under any drawing-action of the roll or coil and said. tension devicealso prevents strip A under the possible slight engagement of the edge of blade 19 with device to render the same adhesive. As the strip A.

the backward movement of thesaid strip when said'blade is'moved toward said tension device.

Having thus described my invention, I

claim as new and desire to' secure by Letters Patent.
