GEORGE E. BRITTAIN, 0F HAVERHILL, MASSACHUSETTS, ASSIGNOR TO IRVING L. KEITH, OF HAVERHILL, MASSACHUSETTS.

HOLDER FOR CEMENTING SOLES.

To all whom it may concern:

Be it known that I, GEORGE E. BRITTAIN, a citizen of the United States, residing at Haverhill, inthe county of Essex and State of Massachusetts, have invented .an Improvement in Holders for Gementing Soles, of which the following is a specification.

In the manufacture of certain kinds of shoes, particularly some kinds of McKay sewed shoes, it is customary to cement a tappiece, having a skived shank end, to the inner side of an outer sole, so that the two parts will be held in position while they are stitched. In performing this cementing operation it has been customary to place cement between the two pieces which are to be cemented together, then place them in piles in a press, and press the pieces together, so that they will adhere. As a matter of convenience, the cementing operation is usually performed at some distance from the press, so that the piles of soles must be transferred thereto, and they are liable to be misplaced while this is being done. Further difficulty is encountered on account of the fact that the cemented surfaces are not held in contact until after they are forced together in the press, so that the cement becomes dry before such parts are pressed together to cause them to adhere. Much inconvenience and difliculty is experienced in making the skived shank end adhere, on this account, and it is particularly necessary that this portion be firmly cemented to the sole;

The object of my invention is to provide means for holding the sole parts in stacks, as they are cemented, so that they may be transferred to the press, without danger that they will be misplaced, so that the operation of handling may be greatly facilitated, and further to provide a convenient means for holding the cemented surfaces, and particularly the skived shank ends, in contact so that all portions will be firmly cemented together. I

I accomplish these objects by the means shown in the accompanying drawing, in which,

Figure 1 is a side elevation, and, Fig. 2 is a plan view of a holder made according to my invention. Fig. 8 is an enlarged sectional view on line 33, of Fig. 1.

According to my invention I provide a holder, which comprises a base plate a, pref- Specification of Letters Patent.

slightly under pressure, and having a sole supporting face a on its upper side, said face having its end portions concaved, or upwardly curved from a flat intermediate middle portion to the ends. The particular extent of the upward curvature depends somewhat on the thickness of the soles which are to be placed in the holder, and length of the scarf on the tap, but usually the curvature is preferably approximately as shown.

A pair of coiled springs 79 are attached to the longitudinal sides of the plate a, at a pointapproximately midway between the middle transverse line thereof, and one end, and a second pair 0 are correspondingly attached between said line and the opposite end, said springs being attached by pins d, so that the end of each spring rests on the face a, and is thus caused to be held in upright position, as shown. Canvas straps e are respectively connected to the ends of each pair of springs, disposed at opposite sides of the base plate, so that said straps extend transversely thereon, said *springs having hooked end-portions passing through eyelets in said straps, so that said straps may be readily detached therefrom at one or both ends.

The method of using the apparatus is as follows:The straps e are disconnected at one end from their respective springs, the latter being held firmly in upright position by their own strength. The cement is applied to the surface of a tap-piece, and a sole-piece, and the two are placed together, so that the edges coincide. The two pieces are then placed on the base-plate 0:, so that the toe ends thereof, in case the sole is of the largest size, extends nearly to the middle of the base-plate, and the skived portion of the tap-piece extends adjacent one end thereof, the heel portion of the sole overhanging beyond the end, and other cemented soles and taps are placed thereon in a stack. Cemented soles and tap-pieces are likewise stacked on the opposite end portion of the base-plate, as shown in Fig. 1, the rights being placed on one end portion of the base, and the lefts on the other, and the two stacks thus being placed toe to toe. If the soles are smaller than the largest sole which the holder is adapted to receive, the skived end of the tap will be held at a greater distance erably of wood, which is adapted to bend from the end of the plate a than that shown, the soles being preferably placed so that the middle portion of the forepart is opposite the corresponding springs. hen a sufficient number of soles have been thus placed on the base, the straps 6 will be drawn over the top of the respective stacks and fastened, and, in doing this, the springs will be stretched so that the straps will be drawn down onto the soles which will be compressed sufficiently to hold the surface together and prevent the cement from drying.

As the springs are held in upright posi tion they will assist materially in holding the soles in position while they are being stacked, and, after the canvas straps have been fastened over the soles, they will also securely hold the soles in place while the holder is being transferred to a press. A plurality of holders thus filled are then placed, one on the other, in a press and all the soles on each holders are compressed at one time.

While the surface of the upper soles of each stack will not be level before they are compressed, the compression of the higher portions will be sufficient to permit compression of the lower portions, so that all parts of the tap-pieces will be placed under some pressure, as indicated in Fig. 1, which will be sufficient to cause the cemented portions to adhere. The base-plates are also adapted to bend somewhat to conform to conditions.

The degree of upward inclination, or curvature may be varied somewhat according to conditions, such as the length of the skived portion on the tap and thickness of the sole, the extent being sufiicient to cause all the slrived portions of the taps in the stack to be pressed against the sole, so that this portion of the tap is firmly cemented. By having the face a formed on a gradual upward curve, from a point adjacent the springs to the end of the base, soles of differentlengths may be cemented on the same holder, as the upwardly curved face will hold the shived portions against the soles in any position in which the strap is drawn over the middle portion of the sole foreparts. In case the device was to be used to cement whole soles the upwardly curved face would, obviously, not be necessary.

An important advantage of the concave or upwardly curved face of the base, over a flat inclined face, is in that the sharp angle which would necessarily be formed between the two faces would mark the bottom sole to such an extent as to deface it. This is, however, avoided with the construction shown and no special care needs to be observed as to the exact position in which a sole shall. be placed thereon. As the straps e are of textile material and relatively thin, as compared with the soles, they will not interfere with the compressing operation, and they may be readily disconnected when the stacks are removed from the press.

I claim 1- 1. A holder for cemented soles comprising a base-plate having a sole-supporting face, a pair of coiled springs mounted at opposite sides of said face and held by their resilience, in vertical position to form horizontal guiding and holding devices for the soles, and a strap connected to the free ends of said springs, substantially as described.

2. A holder for cemented soles and skived taps comprising a base-plate having a concave sole-supporting face extending upwardly toward the end thereof, to hold the skived portion against the sole, and means to press a stack of soles onto said face, substantially as described.

3. A holder for cemented soles and skived taps comprising a base-plate having a concavesole-supporting face extending upwardly from the middle portion toward each end thereof, and means on said plate to press a stack of soles onto each concave endportion thereof, substantially as described.

4-. A holder for cemented soles and skived taps, comprising a base-plate having a solesupporting face thereon, said face having a flat portion and an upwardly inclined por tion leading from said flat portion to the end of the plate, and 'a yielding clamping means at opposite sides of said face and extending thereover for pressing a stack of soles onto said face, substantially as de scribed.

5. A holder for cemented soles and skived taps comprising a base-plate having a concave sole-supporting face extending upwardly toward the end thereof, a pair of vertically extending longitudinally extensible springs mounted on said plate at opposite sides of the middle portion of said face and a strap for connecting the free ends of said springs, substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

GEORGE E. BRITTAIN.
