MACHINE FOR CRIMPING SHOE-QUARTERS.

CPEZCIFLCATIQN forming part of Letters Patent No. 325,267, dated September 1, 1885.

(No model.)

T 0 CLZZ whom it may concern:

Be it known that I, Tnorms NALLY, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Crimping Quarters, of which the following is a specification.

This invention has for its object to provide means for crimping thelower edge oftheinsidc quarter of a boot or shoe for the purpose of forming a stop or gage for the'vamp and to locate on the quarter the fullness required to enable the inner side of the upper to be properly fitted to the innerside of the last, as described in my application for patent for an improve ment in boots and shoes filed with this application.

The invention consists in crimping-jaws or series of j aws formed to corrugate the inside quarter in the manner above indicated, and in the combination, with said jaws, of means for operating them and of a stop or gage to guide the operator in placing the quarter in the proper relation to the crimping-jaws, all of which I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of my improved crimping-inachine. Fig. 2 represents alongitudinal section of the same. Fig. 8 represents asection on line :r m, Fig. 2. Fig. 4 represents a top view.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents a fixed bed, adapted to berigidly attached toabench, Z), or other suitable support.

0 c 0 represent crimping jaws,whieh normally project above the upper surface of the bed a, the projecting parts being substantially triangular. Said jaws may be rigidly attached to a lever, d, which is pivoted to the bed at e, and is vertically movable with the jaws, so that the latter can be depressed below the upper surface of the bed to enable the leather to be easily removed after crimping, the bed having slots through which the jaws move. The lever (1 may be supported when the jaws c are in operative position by an y suitable means-as, for example, a cam-lever, g, pivoted at htolugs on the bed a and bearing against the lever (Z.

i represents a leverpivoted at j to the bed a j and provided with recesses 0, receiving the jaws c.

It represents a stop or gage projecting up wardly from the uppersurface of the bed aand constituting a guide for the operator, who places the forward end of the quarter to be crimped against said guide, the distance of the corrugations from said edge being determined by the gage.

The lever '6 is connected byarod, m,or other convenient connecting device with atrcadlepz, whereby the lever may be depressed to cause thejaws to corrugate the leather.

The operation is as follows: The operator having placed the inside quarter g on the bed a in the position shown in Fig. 4, and thejaws a being raised and rigidly supported by the cam-lever g, the lever i is depressed and its rccesses 0 force the leather down 'upon the jaws 0, thus crimping or corrugating the latter at its lower edge, the forward corrugation being so located that it acts as a stop or gage for the vamp, preventing the rear end or corner of the latter from creeping over upon the quarter during the stitching operation, as dcscribedin my other application above referred to. The quarter may be released by depressing the jaws c and raising the lever i, the movability of the jaws c obviating the necessity of raising the lever 13 so high as would be necessary if the jaws were not movable. I prefer to provide the lever z with a handle, 6, projecting back from its pivot to enable the operator to conveniently raise said lever.

In machines for crimping the inside quarter of rights the gage 7a should be at the opposite side ofthejaws from the side on which it should be located for crimping the inside quarters of lefts. There may be one or more jaws c and corresponding recesses c. I prefer three,however, as shown.

I do not limit myself to the devices described for operating the jaws, but may modify the same variously.

The bed a is preferably provided with ad j ustable gagesj j, which regulate the extent to which the quarter projects over or between the jaws, and therefore regulates the length of the corrugations.

I claim 1. The COlIlbllJZltiOll,Wibh a fixed bed,a, made ,with an opening or openings therethrough, of

the jaw or jaws a, supported in the lever d on the under side of thebed, said jaws being movable through said opening or openings to prot ject above the bed, means, substantially as do scribed, for supporting said lever in the elevated position of the jaws, a lever or bar, '23, having recesses a, corresponding and operating in connection with the jaw or jaws 0, and means for operating said recessed lever, as set forth.

3. The co1nbination,withafixedbed,a, made with an opening or openings therethrough, of

theja-w or jaws 0, supported in the lever d on the under side of the bed, means for supporting said lever with the jaws projecting above the bed, a lever or bar, i, having recesses a, corresponding and operating in connection with the jaw or jaws 0, and a gage, is, upon said bed, as shown, and for the purpose set forth.

4. The combination of the bed having the adjustable gages j j with the crimping-jaws c and c, as set forth.

5. In a leather-crimping machine constructed and operating substantially as herein described, the combination,with the bed thereof, of the adjustable gagesjj and is, For the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two sub scribing witnesses, this 18th day of J une,1885.

THOMAS NA LLY.
