Figure 1 is a persnective"view of a well chine illustrating the manner and use of'my invention;

ing in increased production and lower manufacturing cost of the billfold or other article.

To this end thereof. the invention consists essentially in a work-quiding attachment which may be removably applied to the fixed guide ledge or shelf of sueh a machine. As

. seen in Fig. 2 of the drawings, the atta hmcnt consists of a strip of sheet metal 14 of substantially the same width as the width of the shelf (lange 9, said shcet metal strip being of sufiiciently greater length than said fiange wherebv the ends of the strip 14 may be inwardly bent as at- 15 to provide clampinp; hooks engaging over the ends of the flange 9 and a2ainst the under side of said flanqe to thereby detachably hold the strip 14 in superimnosedrelation upon the upper surface of said fiange 9.

The sheet metal strin 14 adjacent one of its ends has a part 16 integrally f0rmed upon one edoe of the strin and. extending longitudinallv thercof. This part is bent inward ly and downwardly in substantiallv parallel relation to the upner face of the strip 14 and closelv adjacent thereto to thereby provide a guiding fian.qe on said sheet metal strip co tiguous to the gluingx roller or dise 6.

In the use of the device above descbed, the maro:inal ed;re portion of the flexible leather or fabrie work piece is placed by the operator upon the upper surface of the strip 14 With the ed9e thereof extending under the flanae 16. and in bearing contact with the loend in the metal sheet at the juneture of sa d fianae W th the edge of the strip 14. T his flan9:e therebv effeetuallv prevents the extreme edsre portion of the fabrie or leather sheet from bu ckling or turniny: upwardly, as the sheet is moved beneath said flange and advanced hetween the gluing dise and the pressure dises 8. Thus, as the sheet is fed between the dises, the glue or other adhesive will be accurately and preeisely applied to the predetermined limited marginal edge portion of the under side of said sheet. If the adhesive is also to be applied to other edges of the sheet, this operation above deseribed is repeated. Of course, a certain amount of the glue previously applied to the marginal edaes of the sheet will be taken of and collected on the upper surface of the sheet metal strip 14. However, by keeping a number of these attachments on hand, aftcr a certain period of use of one attachment, it may be readilv removed from the fiange 9 of the supporting ledge or shelf, and immersed in a suitable cleaning solution, and

another clean guiding attachment substitut ed in its place.

In Fig. 4 of the drawings, I have shown an alternative embodiment of the device, in which the sheet metal strip 14 is not provided With the attaching hooks 15 at its ends but adjacent one end thereof and on its rear edgc is provided with the upstanding flange 17 having its upper edge outwardly and downwardly turned as at 18 to provide an attaching lip or hook engaging over the upper edge of the vertical flange 10 of the work supporting shelf and bearing against the rear face of said'flange. The fiange 17 has a part 18 and 19 nressed outwardlv therefrom and downwardly into close parallel re lation to the upper surface of the strip 14. A relativelv narrow flange 20 also extends longitudinally from the inner end of the flange 17 along the rear edge of the strip 14' to the other end of said strin, the said flauge bearing closely against the face of the flau9;e 10 of the supporting shelf. However, if desired this narrow vertical flanae 20 may he omitted. The oneration of this form of the attachment is the same as that above describ d. and as the marginal edge portion of the flex ble material is moved over the surface of the strip 14. as it annroaehes the gluing dise or roller. it is confined closelv by the part 19 of the strip so as to nrevcnt flexin,q or buckling of the edge of the sheet.

From the foregoing description considered in connection with the accompanving drawing, the construction. manner of use and sevoral advantages of the described embodimente of mv invention Will be clearlv understood. It Will he seen that the device is exceedingly simple. ma v be nroduced at verv low cost, and is a valuable aceessory for such gluing machines, since it enables the same to operate with equal accuracy and facilit upon either stiif or flexible materials. thereby nereasing the utilitv of the machine.

Wh le I have herein disclosed several simple and practical embo iments of mv improved attachment, it Will nevertheless ho understood that the device may also be produced in various other alternative forma, and I therefore, reserve the privilege of resorting to all such legitimate changes there n as may be fairly embodied within the spirit and scope of the invention as claimed.

3. In combination with a machine having a work supporting shelf and work engaging means at one end of said shelf, a WOrk-guiding attachment consisting of a sheet metal plaie adapted to be superimposed upon said shelf, said plate having a bent portion forming3: an attaching hook t0 releasably engage a wall of said sl1elf and detachably retain the attachment in fixed relation thereto. and said sheet metal plate being further provided with a longitudinally extending flange integral with one edge of said plate and bent inwardly and clownwardly in spaced parallel relation to the upper surface of said plate whereby the marginal edge of a sheet of flexible material is movably confined between said flange and the plate and prevented from flexing or buckling as said sheet is fed to the work engaging means of the machine.

4. In combiuation with a machine having a work supporting shelf and work engaging means at one end of said shelf, a work guidinq attachment consisting of a sheet metal plate adapted to be superimposed upon said shelf. said sheet metal plate extending the entire length of the work supporting shelf and having inwardly turned hooks at its opposite ends engaging under the ends of the sheli wall to detachably retain said plate in fixed relation to the shelf, and said plate adiacent one end thereof having a fiange integ rally formed with one of its longitudinal edoes extending along the same in close parallel relation with the upper surface of said plate t0 movably confine the marginal edge of a flexible sheet of material between said flan e and the plate and prevent flexing or buckling of the edge of the sheet as it is fed to the work engaging means of the machine.

5. A work supporting and guiding device comprising a sheet metal plate adapted to be superimposed upon a fixed support and having an integrally formed part t0 coact with the support and detachably retain said plate in its applied position thereon, and a work guiding fiange projecting inwardly from one longitudinal edge of said plate in closely spaced parallel relation to the surface of the plate to confine the edge of a flexible work sheet upon said surface and prevent flexing or buckling thereof.

6. A work supporting and guiding device comprising a sheet metal plate adapted to be superimposed upon a fixed support, said plate having an upstanding flange along one of its longitudinal edges constituting an abutment for one edge of a flexible work sheet positioned on said plate, said flange at one end of the plate having a part struck outwardly therefrom and overlying the upper surface of said plate in closely spaced parallel relation thereto t0 confine the edge of the work sheet upon said plate and prevent flexing or buckling thereof, and said upstanding flange being further provided with means to releasably engage a part of the fixed support and detachably retain the sheet metal plate thereon.
