LAST.

SPECIFICATION forming part of Letters Patent No. 674,084, dated May 14, 1901.

Application filed June 9,1896. Serial No. 594,828. (No model.)

T0 0% whom it may concern.-

Be it known that I, EDWIN L. GODING, a citizen of the United States of America, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Lasts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in lasts.

The preferred formof my invention, as herein shown, gives special strength for use on beefing-machines; and to this end it consists in forming a vertical longitudinally-extended socket in the heel portion of the last continuous with the spindle-hole and of less width than the diameter thereof. This socket may extend to the bottom of the last or to the metal plate usually attached thereto. A bearing-plate may be inserted in the bottom of the socket to receive the anvil of the heeliugmachine.

My invention is applicable both to lasts made in a single piece and to divided lasts, and in the latter case it provides a greatlyimproved divided or hinged last. Lasts have been heretofore hinged together simply by one hinge, which has usually been of the common butt hinge type. My improvement, however, differs from this old style of last and employs two distinct and separate unions arranged adjacent the opposite sides of the last and each secured in place so as to brace and cooperate with the other union in producing an extremely rigid last incapable of permitting the heel part to shift or twist out of alinement with the fore part when the last is in extended position. As the simplest means of overcoming the said twisting or wrenching of the parts relatively to each other I have joined them together simply by links or plates, this being the simplest kind of a hinge. In this latter case the socket extends from the spindle-hole forwardly to the line of division, and a connecting-plate pivotally secured to the front part extends into the bottom of said socket and is secured therein, serving to connect the two parts of the last together and for a bearing for the anvil of the heeling-machine.

In the drawings herewith accompanying and forming a part of this application, Figure 1 is a top plan view of a last, showing socket and section of heeling-machine anvil adapted to fit therein, the toe part being broken away. Fig. 2 is a central vertical longitudinal section, partly in elevation, of a divided last provided with my improvement, the dotted lines showing the position of the heel part relative to the toe part when being inserted in or removed from a shoe. Fig. 3 is a transverse sectional view of Fig. 2, taken on lines w 00; and Fig. 4 isa view in perspective of the fore part of the last with two connectiug-plates, one extendinginto the socket in the heel part of the last.

Same letters refer to like parts.

In said drawings, A represents the heel part of a last having a vertical spindle-hole B therein and a socket O. This socket may be formed readily in whole lasts by boring the spindle-hole entirely through the last, inserting a saw in said hole, and making a lougitudinal saw-cut therein. In a divided last the socket may be made by a saw-cut extending from the front of the heel part backwardly to its intersection with the spindle-hole.

To the bottom of the last may be secured the usual heel-plate D, and the anvil of the heeling-machine may strike directly thereon, or a vertical bearing-plate I to receive the end of the anvil may be inserted in the bottom of the socket, as seen in Fig. 2.

The heeling-machine anvil when specially adapted to be used with lasts involving my improvement has the usual cylindrical portion E and a flange F extending therefrom and adapted to enter the socket in the last, the cylindrical portion fitting in the spindlehole B. The flange entering the socket prevents the last from twisting on the anvil and gives a long hearing or seat for the anvil.

In the divided last a socket H is made in the rear wall of the fore part, and the end of a metallic plate I is pivotally mounted therein on a pin J, extending transversely through the last. Said plate extends rearwardly and is securely mounted in the bottom of the socket in the heel part. Said plate may extend to the rear wall of the spindle-hole. To strengthen the connection between the two parts of the last, an additional connectingplate K may be used.

I am not aware that a plurality of connec tions of any sort have heretofore been employed in joining the parts of a divided last. The arrangement of the hinges one at each side of the last prevents all lateral twist, and such a last is capable of sustaining very great pressure exertedin any plane either laterally, vertically, or diagonally and renders the last capable of being used in any position found desirable or necessary in the manufacture of boots or shoes. The union or hinge which I prefer to employ consists simply of a metal plate, this being advantageous on account of its cheapness of construction and convenience of application.

To enable the last to be readily inserted in and withdrawn from the boot, a portion of the heel part adjacent to the fore part is removed, preferably on a diagonal line, as seen at L. This taken in connection with the pivoted connecting-plate permits the heel portion to swing on the pivot into the position shown in dotted lines in Fig. 2.

In operation the anvil of the heeling-machine is inserted in the socket and spindlehole, and striking on the heel-plate or the vertical plate, as the case may be, has a hearing extending nearly the entire length of the heel, while the web in the socket prevents the last from twisting on the anvil. The manner of connecting the two parts of the last brings the adjacent walls close together when the two parts are in their normal positions and effectually prevents them from moving relatively to each other except up-- wardly, and thus, while enabling the last to be readily inserted in and removed from the boot, does not destroy its adaptability for use in lasting.

It will be understood that while I have shown my invention in the form in which I prefer to embody and use it, yet I am not restricted thereto, inasmuch as various changes in form and arrangement of parts and various substitutions may be resorted to without departing from the spirit and scope of my invention, and accordingly I do not otherwise limit myself than as expressed hereinafter in the claims, and while I regard as very important that feature of my invention which relates to the provision of means in a last for preventing the twisting of a last on the heeling-anvil and affording a long bearing in the last for use on heelingmachines, yet my invention is advantageous, when considered broadly, for divided lasts in general, and I have accordingly in certain of my claims set forth this feature of the invention without reference to specific construction or to other features of the invention.

Having thus described my invention and its use, I claim- 1. In a transversely-divided hinged last, the combination of a fore part and heel part with a plurality of hinges inserted and secured in the body of the last, one hinge being near one side of the last and another hinge being near the other side of the last, the opposed ends of the fore part and heel part contacting below the hinges when in alinement.

2. As a new article of manufacture, a last divided transversely to its length and having vertically-disposed sockets in the adjacent walls thereof, said socket in the heel part extending rearwardly to the spindle-hole and being of less width than the diameter thereof and forming with said spindle-hole a socket for the anvil of the heeling-machine and a connectingplate pivotally secured in the socket in the fore part of the last and rigidly secured in the bottom of the socket in the heel part and forming a bearing for the end of the heeling-machine anvil, substantially as and for the purposes set forth.

3. The combination of the fore part of a last with an upwardly-swinging heel part, of a plurality of means for hinging said parts together at their sides, one of said hinging means being near one side of the last and another of said hinging means being near the other side of the last, to prevent deforming of the last, said fore part and heel part being formed with a space between their upper opposed portions and with contacting end surfaces below the axes on which the heel part turns.

4:. A divided last having its forward portion and heel part arranged to turnon each other, and connected together by independent unions secured at their ends in the opposite portions of the last adjacent the sides of the last, substantially as described.

5. A divided or multipart last having its heel part capable of swinging on the rest of the last, said heel part being connected'to the forward portion of the last by two independent unions extending longitudinally of the last and permanently secured therein adjacent the sides of the last, substantially as described.

6. A divided or multipart last having its fore part and heel part connected together by a plurality of plates set vertically in the last and permanently secured to said heel part and fore part respectively, substantially as described.

7. A divided last having vertical independent kerfs in the contiguous walls of its fore part and heel part respectively, combined with plates fitting into said kerfs and pivotally mounted therein at one of their ends, substantially as described.

8. As a new article of manufacture, a last having a portion removed from the top thereof at a point at or near the ankle and then diemcee vided transversely into a fore part and a heel part; said parts being joined together by transversely-bending nnions1ocated,one near one side portion and another near the other side portion of the last; and opposed ends of the fore part and heel part contacting below said unions when in alineinent, said unions having body portions extending lengthwise of the last.

9. As a new article of manufacture a last having a V-shaped portion removed from the top thereof and divided transversely into a fore part and heel part; a plurality of sets of holes in opposed Walls of said parts and adapted to register; and a plurality of transversely-bending unions, the shanks of which are secured in said holes; one set of holes and one of said unions being near one side and another set of holes and another of said unions being near the other side of the last; and the opposed ends of the fore part and heel part contacting below said unions when in alineinent, said unions having body portions extending lengthwise of the last.

10. In a transversely-divided hinged last, the combination of the fore part and heel part with a plurality of hinges inserted in the body of the last, one hinge being near one side of the last and the other hinge being near the other side of the last; and means for securing the inserted portions of the hinges in place, the inserted portions of the hinges extending in the direction of the length of the last.

In testimony whereof I affix my signature, in presence of tWo witnesses, this 30th day of May, 1896.

EDWIN L. GODING.
