HARVEY I). REED, OF NORTH ABINGTON, MASSACHUSETTS.

SHOE-LAST.

nooeeie.

To all whom it may] concern Be it known that I, HARVEY D. REED, citizen of the United States, residing at North Abington, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Lasts, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in shoe last and more particularly to a movable block in connection therewith and the primary object of the invention is to provide a shoe last with improved means for adjusting the blockthereof to various positions.

A further object of the invention resides in providing a removable block on a last having a cam arranged in connection therewith to dispose said block to various positions on the last.

A still further object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efiicient and useful in operation.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming a part of thi application, Figure 1 is a side elevation of a last showing the block thereon in its lowered position. Fig. 2 is a similar view showing the block in its raised position, through the action of the cam. Fig. 3 is a section as seen on line 33, of Fig. 2; and Fig. 4 is a detail section as seen on line 4-4, Fig. 1.

In describing my invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a shoe last of the usual or any preferred character, having the removable portion 2 mounted thereon to complete the formation of the instep thereof. This block is provided in the under face adjacent its forward end with a recess 3, which is slightly inclined to receive a rearwardly inclined pin 4 formed on the body of the last. A forwardly inclined spring forced pin 5 is also provided on the body of the last rearwardly of and in a plane above the pin 4,

the same being normally held in its extended position by means of a spring 5 adapted to be received in the lower end of a channel 6, formed in the block 2 at its upper end. This channel, passes completely through the block as clearly shown in Fig. 4 of the drawing and is adapted to be entered from the outside. The socket 3 loosely receive the pin 4 therein which admits of the upper end of the block 9. being raised slightly at its upper end from the cavity formed in the body of the last and I have provided an improved means for raising this block from the last and retaining the same in its adjusted position.

Formed in the side of the last 1, adjacent the cavity therein formed, from which the block 2 is cut, is a recess 7, and removably secured in said recess by means of a screw 8, is a cam 9. The block 2 which, as stated, completes the formation of the last, obviously has a portion projecting over the recess 7 and this portion of the last immediately projecting over the recess, has a metal plate 10 secured thereto, with which said cam 9 is adapted to contact. A groove 11 is formed in the cam 9, with which a tool of any desired character may be engaged so as to turn said cam on its pivot and when turned in one direction, so as to engage said plate 10, as shown in Fig. 2 of the drawing, the upper portion of the block 2 will be raised. The cam 9 is held tightly in position by means of the screw 8 so that considerable force is necessary to turn the same and through this medium, the cam will be frictionally retained in any adjusted position. In the manufacture of lace shoes, the block 2 is in its lowermost position, as shown in Fig. 1, but in manufacturing shoes of the button type, or any form of shoe other than that in which laces are adapted to be provided, the block must, necessarily, be raised. Various means are now in use, which eliminate the necessity of providing a movable block but these means are not alone crude, but require considerable labor in the application of the same to use, thus causing greater expense in the manufacture of the shoe. My improved means, however, obviates these difticulties and affords a means whereby the block may be raised and lowered, as desired, with little or no difficulty. Blocks of various shapes and sizes may be substituted for the one shown by merely removing the block 2. The removal of block 2 is a simple matter, requiring merely the introduction of a tool or instrument in the channel 2 to force said spring forced pin 5 inwardly.

From the foregoing description of the construction of my improved device, the operation thereof will be readily understood and it will be seen that I have provided a last having an improved means for raising and lowering the block thereon. It will still further be seen that the device is simple and durable in construction, inexpensive to manufacture, and will be very efficient and useful in operation.

While I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be re sorted to without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described this invention, what I claim is 1. In a shoe last, a body, a block applied thereto, to complete the formation. of the same, means to movably support said block on the body, a disk-like cam mounted for oscillation on the body and arranged for engagement with a portion of said block to adjust the latter to various positions with respect to the body, a wear plate carried on the block to receive said cam in contact therewith, and means formed in said cam whereby to permit the same to be readily engaged and operated.

2. In a shoe last, a body, a block applied thereto to complete the formation of the same, means to movably support the block on the body, said body being provided with a recess in one side thereof, and a disk-like cam mounted for oscillation in the recess and arranged to contact with a portion of said block to adjust the latter to various positions with respect to the body, said cam being provided with a diametrical slot in its outer face to receive an instrument therein for the actuation of said cam.

3. In a shoe last, a body, a block applied thereto to complete the formation of the same, means to movably support the block on the body, said body being provided with a recess in one side thereof terminating in the face upon which said block is mounted, a disk-like cam mounted for oscillation in the recess and arranged for engagement with the under face of said block to adjust the latter to various positions with respect to the body, the outer face of said cam being provided with a slot to receive an instrument for the actuation of the cam, and a wear plate applied to the under face of the 1 block to receive said cam in contact therer with.

In testlmony whereof I hereunto affix my signature in the presence of two witnesses.
