HOLDER FOR CEMENTED SOLES.

Specification of Letters Patent.

Patented Dec. 26, 1916.

Application filed January 27, 1914. Serial No. 814,641.

a citizen of the United States, residing at St. Louis, State of Missouri, have invented an Improvement in Holders for Cemented Soles, of which the following is a specification.

In the manufacture of shoes, it is common practice to reinforce the outer soles with tap soles which are cemented and later sewed thereto. In cementing these so-called taps to soles, it has been customary to apply a coating of cement to the contacting surfaces, place them together in the positions in which it is desired to have them adhere, and then place them in a stack of a dozen or more on a board, or holder designed for the purpose, a form generally employed being disclosed in my Letters Patent of the United States, #l,01 6,544, dated February 6, 1912. A considerable number of cemented taps and soles are thus prepared and alternately arranged 'on these holders and then these holders, with the cemented taps and soles stacked thereon, are placed in a press one on another in a stack, so that the bottom of one holder rests on the top of a stack of soles directly beneath. The whole stack of holders, with the cemented soles and taps thereon, is then subjected to pressure and permitted to remain in the press, while thus held under pressure, until the cement is thoroughly dry. This method is open to a number of serious objections, chief of which is the fact that the cement between many of the soles and taps becomes dry, before they are pressed together, because portions are not held in contact and are exposed to the air, so that, when the pressure is finally applied to bring these surfaces into contact, it is ineffective, and, as a result, only portions, if any, are caused to adhere. Furthermore, in pressing such a large number of soles together, a heavy pressure is required which is'frequently insufficient for the purpose, and, also, it is found difficult to secure the desired distribution of pressure. This method is also inconvenient in that it frequently happens that a particular lot or case of soles, held on one holder, of the various holders held in the press, is required before the others are, so that it is necessary to remove all of the holders from the press, to secure the particular one desired.

The object of my invention is to provide a sole holder of the type above referred to wlth means whereby the stack, or case of soles which is placed thereon may be compressed to the full extent desired, immediately after the piling operation has been removal of the holder from the press and the setting of it aside until the cement is dry.

A further object of my invention is to provide a device of the above character, in which a pressure-applying member may be forced into pressing relation with a sole- 7 supporting member, and in which a simple and durable means is providedwith which said members may be readily locked in said pressing relation while thus held, and which is adapted to permit an equally ready unlocking thereof, to permit theeasy removal of the soles after the cement is dry.

I accomplish these objects by means of a form of clamping device which comprises a pair 'of telescopically arranged clamping members, in the form of a pair of oppositely disposed U-shaped straps, one of which has cam levers thereon arranged to permit rela tive movement between the arms of the straps in one direction and to engage the arms of the other strap and prevent relative movement thereof in the opposite direction, said straps being formed to embrace 21 pair of sole holders or boards between which the soles are stacked, so that these boards may be placed in a press immediately after the soles are stacked, and forced together and locked in this position and may then be removed from the press and set aside to permit the cement to set while the pressure on the soles is retained.

Figure 1 is a side elevation of a sole holder made according to my invention. Fig. 2 is a part end elevation, and part cross-sea tional view at the middle thereof, showing the parts in locked position. Fig. 3 is a similar view illustrating the method of removal, and Fig. 4: is a detail sectional view of the locking means which I employ.

In the drawing the wooden sole-supporting block a, is of oblong form and provided with raised end portions, as disclosed in my said rior atent. Accordin to m invention I provide saidblock a with a rigid U-shaped flat metal strap 5, which is preferably firmly secured thereto midway thereof, with its intermediate portion extending across the under side thereof, and within a recess formed therein, so that the lower side of said strap is flush with the bottom of the block. The sides or arms 6, of said strap each extend vertically at each side of the block for a suit-able distance, forming standards which may be varied according. to the height of the stack of soles which is to be placed on the holder. A wooden presserblock 0 is provided. which is of the same length, but of somewhat less width than thebase block a and has suflicient rigidity to revent ieldin under ordinar conditions of use. A rigid, U-shaped, flat metal strap d is also provided which is adapted to be placed astride the block 0, so that its side sections, or arms d may depend perpendicularly therefrom, the distance between the outer sides of said arms d being slightly less than. that between'theinner sides of the standards 5, so that the former may move freely between the latter, telescopically, as

shown in Fig. 2. Clips 6 are mounted on the upper end-portions of the standards 6, said end-portions being thickened to increase the strength thereof, and are securedin position thereon by pivots f on which cam-levers g are mounted, said levers being arranged in apertures 6 which extend through said standards Z2, and said pivots being eX- tended through thestandards at each side of said apertures and through the sides of said clips in suchposition that the inwardly bent end-portions e of said clips may firmly engage the. outer sides of the standards I). Theinner-portions e of said clips are held at a distance from the inner sides of said standards which is slightly greater than the thickness of the. arms d and the distance between the sides ofsaid clips is made to correspond to the width of said arms (Z, to permit. said arms cZto slide freely in the sockets thus formed therefor.

The inner ends of the cam-levers g are formed eccentrically with relation to their pivots. and are so arranged that, when the outer ends of said levers are moved down, either by gravity or by hand, their inner or eccentrically formed ends will be forced against the sides of the arms d and spring them.- inwardly slightly and press them against the inner surfaces of the clip portions 6 as shown in Fig. 4, so that said arms will be caused to have a strong frictional engagement with said clips. After these parts. have thus beenbrought into engagement, any, tendency to draw, the arms cl upward from the base block a will tend to swing the cam levers g inwardly still more. so that said levers will bind said arms all the more tightly against the clip-por- The manner in which the device is em-,

ployed is as follows :The presser block a and U-shaped strap (Z. having been removed, the cemented taps and soles are piled toe to toe alternately on thebase or sole-supporting block in two stacks, as indicated in Fig. 1, and as described in my said prior patent, and when the desired number of soles and taps have thus been. placed thereon the pressure block 0 is laid on top thereof, and the strap (Z- is placed astride the same and its arms (1 are passed. down into the clips 6,

so that its middle portion may be pressed firmly against said block 0. The stacks of soles will thus be held in the positions in which they were piled while the whole device isv then placed between the'members m, a, of a press, and the two blocks a and 0 are forced together so that the soles andtaps are pressed together to the desired extent, as shown in Fig. 1. As the arms (5 are forced inwardly, the cam-levers will be automatically held in gripping engagement therewith by the gravity of, the outer portions thereof, so that, as soon as the, downward pressure of the press is removed, said lovers will automatically grip the armsand hold them from upwardnmovement. The holder may thenbe-removed from the press and the pressure which was applied thereby to the holder will, to a large extent, at, least, be retained automatically. However, as a slight outward movement of the arms may occur before the cam-levers grip the arms with sufiicient force to hold them, I consider it preferable to press down said levers by hand before removing the pressure of; the press, s o that, all the pressure thus applied will be retained. The holder is then removed from the press, so that the soles in another holder may be pressed together immediately thereafter in the same press, each successive holder being set aside until the cement is dry. After the cement becomes dry I the soles are removed from their respective holders by merely inverting the holder and holding it by the base plateand then striking the middle portion of the strap (Z against the floor or bench, so that the strain onthe leversh is sufliciently relieved to, per mit them to be thrown down by the force of the blow, as shown in Fig. 3, completely disengaging them from the arms (Z. .sovthat the standards 6 may then be withdrawn from the arms 03, thereby permitting the soles to be readily removed.

The whole device is of simple and durable construction and, by providing frictional engaging devices for locking the plates together, the locking may be performed at any point, within the necessary limits, to which the presser-block is forced by the press, so that all pressure secured by the press is retained, and the effectiveness of the locking parts will not be appreciably affected by wear.

When employing devices of the above described character, the work of cementing the taps and soles may be much more efiectively accomplished, with my improved device, than with my prior device, as the full pressure may be applied as soon as the soles are stacked and before the cement becomes dry, so that the pieces will be caused to adhere firmly. My improved holders are also more convenient, as they do not have to be piled in a press, and any particular holder may be opened without disturbing any other holder, which is a matter of great convenience in a shoe factory. Also a fewer number of holders are necessary to do the same amount of work.
