To all whom it may concern:

Be it known that I, ADoLPH F. Born, of

Rochester, in the county of Monroe and State of N ew.York, have invented certain new and useful Improvements in Ap aratus for Lasting Boots and Shoes; and I $0 hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon. My present invention relates to the art of manufacturing boots and shoes; and it has for its object to provide an improved apparatus for securing the boot or shoe upper to the last and stretching it thereon in'readiness to1 be stitched or otherwise secured to the so e.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features 'being pointed out in the claims at the end of the specification.

In the drawings, Figure 1 is a perspective view of an apparatus constructed in accordance with my invention. Fig. 2 is a bottom plan view of a shoe 011 a last, illustrating the operation of the apparatus. Fig. 3 is a rear elevation thereof, and Fig. 4 is a side elevation of a modification.

Similar reference-numerals of the several figures indicate similar parts.

In the manufacture of boots and shoes it has been the general custom heretofore to stretch the upper portion of a shoe over a last by means of pincers and to secure it at various points with tacks, which are subsequently removed after the edges of the upper have been stitched to the sole. The principal disadvantages in this operation arethat considerable time is required to last each shoe, and unless the operator exerts great care one portion of the upper maybe stretched more than another, resulting in the making of a poorly-fitting shoe. Further, the tacks employed are driven through the insole of the shoe into the last, causing the insole to be roughened at numerouspoints on its surface and the last to be perforated or indented on the bottom to such an extent that after numerous shoes have been made thereon the tacks will not hold in the last and it is necessary to discard it. My invention has for its object to provide means for overcoming these dis advantages, and in the present illustration I have shown one embodiment of the invention, which comprises a drawing device attached to the edges of the upper and means supported on the last for placing the drawing device under tension.

In illustrating the invention I have shown it employed in the manufacture of a turnshoe, the insole 1 thereof being secured over the sole of the lasting-block located within the shoe-upper, the edges of which are shown and indicated by 2 in Fig. 2. The drawing device is preferably formed of fine steel Wire 3, secured to the edges 2 of the upper at the toe portion and the sides thereof by overcast stitches 4, extending rearwardly to the instep portion of the shoe, (indicated by 5.) Embracing the heel of the shoe and bearing against the heel of the last is a frame 6, hav ing diverging curved arms 7 and a forwardlyprojecting arm 8 arranged above the arms 7 and located between them. The forward ends of the arms 7 are curved downwardly, and their upper ed es extend outwardly beyond their lower e ges, adapting them to fit snugly against the narrower tapering portion of the heel of the last below the sole. sired, these arms may be provided on their faces with a covering of rubber or similar material, (indicated by 9,) adapted to give them a firmer grip and which will prevent any possible abrasion or discoloration by contact with the shoe-lining, as the latter is usually operated upon when in a dampened condition. Between the arms 7 a lug or finger 10 is formed by striking up a portion of the frame 6, and as this projection is held firmly in engagement with the heel of the shoe on the last the rear end of the frame is prevented from tipping upwardly when a strain is exerted thereon. The arm 8 is adapted to rest against the sole of the shoe, and its forward end terminates in proximity to the instep ortion thereof, where an upwardly-exten ing lip 11 is provided, having;

vice or mm 3 may be readily passed. The

eye 12 forms a guide which by its location relatively to the instep portion of the shoe causes the drawing device to pull inwardly to stretch the upper at each side of the instep as well as at other portions of the shoe.

The means employed for straining or affecting the longitudinal movement of the drawing device is mounted on the frame 6 and comprises a revoluble post 14, preferably journaled in the arm 8 and secured at its lower end to a ratchet-wheel 15. The latter is located in a transversel -extending recess 16, provided between the upper and lower walls of the arm, and also located therein is a spring-operated pawl 17, having an outwardly-extending end 18, which may be operated to throw the pawl out of engagement with the ratchet-wheel. The upper end of the post 14 is made angular, as indicated at 19, to receive the correspondingly-shaped end of an operating handle or key, and extending transversely of said end is a slot 20, adapted to receive the free ends of the drawing device 3 or wire.

The modified form of the frame illustrated in Fig. 3 shows the winding member or post 14 supported between the ears 21 and 22 of a bracket 23, secured to the rear of the frame 6. At its lower end the post is also provided with a ratchet-wheel 15, with which cooperates a dog or pawl 17.

The operation of lasting a shoe with the apparatus embodying my invention will be readily understood. The insole 1 being placed on the last, the shoe-upper is placed thereon so that its edges, which are provided with the wire 3, are in the usual position above the edges of the insole. The frame 6 is then fitted over the heel of the shoe, the arms 7 7 firmly grasping opposite sides of the last, and the arm 8 bearing against the shoesole. The ends of the drawing device or wire 3 are then brought together and passed into the guide-eye 12 and their free ends secured to the post 14 by inserting them in the slot 20. By applying a key or wrench to the angular end 19 of the post the operator may force the ends of the wire downwardly to secure them in the slot, and by rotating the post the wire may be drawn rearwardly to produce an equal tension on all points of the toe and side portions of the upper and se curely fit it to the last. The sewing opera tion may be then performed in the usual manner, and when completed the surplus edges, to which the wire 3 is attached, may be trimmed off and the frame 6 removed, permitting the heel portion of the upper to be sewed or nailed to the corresponding part of theinsole, according to the character of the shoe undergoing the process of manufacture.

I claim as my invention- 1. The combination with a drawing device adapted to be attached to the toe and side portions of a shoe-upper, of a mechanism embracing the heel of a shoe when it contains its last, comprising a revoluble member adapted to be connected to said drawing device arranged with its axis extending in a plane at right angles to the plane in which the drawing device lies.

2. A device for lasting shoes comprising a frame adapted to bear against the heel of a shoe containing a last and to extend over the sole thereof, a drawing device arranged on the shoeupper, a revoluble member supported on the frame and adapted to cooperate with said drawing device, the axis of said member extending vertically relatively to the sole of the shoe.

3. An apparatus for lasting shoes comprising a frame arranged to bear against one end of a last inserted in a shoe having an extension adapted to project over the sole thereof, a movable member on the frame, a guide arranged in front of the member and a drawing device located on the shoe-upper having free ends extending through the guide and attached to the movable member.

4. v A device of the character describedcomprising a frame having diverging arms, an upper forwardly-extending arm, a post journaled in the last-mentioned arm and revoluble freely in one direction having an angular portion and provided with a transverse slot.
