SHOE-LAST.

Specification of Letters Patent.

Application filed July 22, 1911.

Patented Apr. 16, 1912. Serial No. 639,950.

To all whom it may concern:

Be it known that I, JOHN S. BUSKY, Jr., a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and useful Improvement in Shoe-Lasts, of which the following is a full, clear, and exact specification.

This invention relates to a class of devices or shoe lasts adapted for use in making footwear.

My invention has for its object primarily to provide a shoe last or device designed to be employed for facilitating the making of shoes, boots, or other forms of footwear for persons and by the use of which persons afflicted with blindness may be instructed to make footwear with great efficiency; to provide a form of shoe last which will permit a welt and insole to be dispensed with in making a shoe or boot, or an insole may be used therein, if preferred; and to provide a shoe last which will permit the upper or vamp of a shoe to be shaped and stitched for proper lasting without the employment of nails or tacks as is incident to the methods in ordinary use.

Another object of the invention is to pro vide a device adapted to be adjusted by the use of a key for shaping the upper or vamp of a shoe in any preferred form after its parts have been stitched together upon the last; and another object of the invention is to provide a retaining device or means in which a plurality of pins are employed and adapted to cooperate with the adjusting device for holding the upper or vamp upon the last so as to permit it to be properly and conveniently stitched or fastened to an insole or otherwise. a

A practical embodimentof the invention is represented in the accompanying drawing forming a part of this specification in which similar characters of reference indicate coresponding parts in all the views, the said invention being more fully described hereinafter and then pointed out in the appended claims.

In the drawing, Figure l is a side elevation, partly broken away and partly in section, of one form of shoe last embodying my invention. Fig. 2 is an inverted plan of the last showing the adjustable device applied thereto. Fig. 3 is an inverted plan of the last with the adjustable device removed, and showing the holding means, and Fig. 4 is a transverse section through the last.

The device 10 has a last 11 adapted for use in making footwear, and said last may be of any preferred size or shape, or may be hollow or its lower portion only may be hollow, as desired. Fastened in any suitable manner within the last 11 is a supporting plate 12 which is curved to conform with the curvature of the bottom of the last 11, and upon said supporting plate is preferably provided one or more upwardly disposed extensions, as 13 and 14.

Upon the underside of the supporting plate 12 is provided an adjusting device 15 adapted for use in shaping the upper or vamp of a shoe in any preferred form after its edges have been stitched together or when said edges have been stitched to a welt, or an insole, or to the sole proper of the shoe. The device 15 consists of two adjusting shaping members or plates 16 and 17 which are adapted to be moved with relation to each other so as to expand or contract the upper or vamp, if desired, when held upon the last. The outer edge of each of the plates 16 and 17 is formed to comply with the exact shape of the shoe, and each of said plates is of a length to extend from the toe to the heel of the last. Upon the inner edge of each of the shaping plates 16 and 17 are a plurality of lugs 18, 19, 20, and in each of said lugs is an obliquely disposed slot 21, 22, 23, through which is disposed a screw or pin 24, 25, 26. The screws or pins 24, 25, 26 are of a size to permit the lugs 18, 19, 20 to be moved thereon whereby the shaping plates 16 and 17 may be directed to expanded or contracted positions. The lugs 19 are somewhat larger than the lugs 18 and 20 and to the lugs 19 are pivoted one end of arms -27 and 28 of toggle links 29. The opposite end of each of the arms 27 and 28 of the toggle links 29 is pivoted to the end of a rack 30 which is guided under a strap 31 fastened to the supporting plate 12. The rack 30 has one of its edges partly provided with teeth, and in mesh with said teeth is a small toothed wheel 32 which is rotatably held upon the supporting plate 12 and has a groove or key seat 33 in one of its faces for reception of a key 34, as shown in Fig. l. The key 34 may be of any suitable shape, and is inserted through an opening in the last for engagement with the toothed wheel By rotating the key 34 the toothed wheel 32 will re revolved and in turn the rack 30 will be directed forward or backward for moving the arms 27 and 28 .of the toggle links 29 whereby the shaping members or plates 16 and 17 will be guided to expanded or contracted positions. The outer edge of each of the shaping'plates 16 and 17 is provided with corrugations or substantially V-shaped notches 35 which serve as guides for permitting the upper or vamp to be accurately stitched to an outer sole of the shoe, if preferred. In each of the shaping plates 16 and 17 are provided at closely spaced intervals a plurality of obliquely disposed slots 36, and through each of said slots is disposed the sharpened free end of one of a plurality of vertically disposed pins 37 of a retaining device or means 38 which is adapted to eoiiperate with the adjusting device 15 for holding the upper or vamp upon the lastso as to permit it to be properly and conveniently stitched, or fastened together, or attached to a welt, or insole.

The retaining device 38 has a plate 39 which is of a formation similar to the bottom of the part of the last bet-ween the toe and heel thereof and said plate has a cutout center, as 39. The plate 39 carries the sharpened pins 37, and is adapted to be moved in a vertical direction so that said pins may be similarly guided through the slots 36 of the shaping plates 16 and 17. At spaced intervals upon one of the inner edges of the cut-out pin carrying plate 39 are a number of projections or lugs 40, 41, 42 and at like spaced intervals upon the opposed inner edge of said pin carrying plate are a number of similar projections or lugs 40, 41 42*, thus said lugs are arranged in pairs, as indicated. The free ends of all of the projections or lugs 40, 41, 42, and 40, 41 42 are curved or struck upwardly, and abutting against each pair of said curved lugs is a wheel 43, 44, 45. Each of the wheels 43, 44, 45 is rotatably held upon a pin 46, 47 48, two of which are provided in the extensions 13 and 14 of the supporting plate 12 while the third pin is held in said supporting plate proper. The face of each of the wheels 43, 44, 45 is provided with two opposed cam-shaped edges, as 46 and 47, which are adapted to contact with the opposed surface of each pair of the lugs of the carrying plate 39. Eccentrically held upon each of the cam-wheels 43, 44, 45 is a pin 49, and each of said pins is movably guided in a slot 49 of spaced lugs 50, 51, 52 provided upon one edge of a rack bar 53. The rack bar 53 is adapted to be movably directed to and fro from the heel to the toe of the last for rotating the Wheels 43, 44,

45 so as to guide the cam edges 46'" and 47 of each of said wheels into engagement with the projections 40, 41, 42 of the carrying plates 39. One edge of a portion of the rack bar 53 at the heel of the last is provided with a number of teeth 54 and meshing with said teeth is a toothed wheel 55 which is rotatably held upon the supporting plate 12 and has a slot or seat 56 for reception of the key 34 which is adapted to operate the retaining device 38 as well as the adjusting device 15. As a means to provide for disposing the carrying plate 39 so that the sharpened points of the pins 37 thereof will normally protrude through the obliquely disposed slots 36 of the shaping plates 16 and 17, as shown in Fig. 1, one or more springs, as 57, are fastened upon the supporting plate 12, and each of said springs is curved so that the ends thereof are in movable contact with the upper surface of said carrying plate.

In using the device 10 for making a shoe, the upper or vamp is fitted over the last 11, and the edges of the vamp are guided over and under the shaping plates 16 and 17. The edges of the vamp are then fastened upon the pins 37 in order to be secured together by stitches or sewed to an insole, or welt. he vamp ma) then be formed into a suitable shape by the adjusting device 15, by the key 34 being used to rotate the toothed wheel 32 of said adjusting device for moving the rack 30 to direct the arms 27 and 28 of the toggle links 29 so as to move the shaping plates 16 and 17 into extended or contracted positions, as preferred, and the sole proper of the shoe is finally stitched to the vamp direct by using as guides the notches 35 of said shaping plates for accomplishing an even and regular form of stitching. lVhen it is desired to release the connection of the vamp with the pins 37 the key 34 is then used for rotating the toothed wheel 55 by which the rack bar 53 will be moved, as above described, to revolve the wheels 43, 44, 45 so that the cam edges 46 and 47 thereof will be forced into en gagement with the projections 40, 41, 42 of the carrying plate 39, and said carrying plate will be lifted against the tension of the springs 57 for guiding the pins 37 within the slots 36 of the shaping plates 16 and 17 whereby the engagement of said pins with the vamp will be released.

In the foregoing description I have embodied the preferred form of my invent-ion, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope thereof.
