Patented Feb. 28, 1939 UNETED STATES PATENT OFFICE 13 Claims.

This invention relates to a shoe last and has for one of its objects a simple and eicient means for manipulating the last to remove it from the shoe after the shoe has been assembled thereon.

Another object of the invention is the provision of a mechanical means whereby the effective manual power may be increased so that the operator may easily effect a manipulation of the last.

A more specific object of the invention is the provision of a last having relatively sliding parts with an accessible means for causing these parts to slide one on the other for removing the last from the shoe.

A still further and more speciiic object of the i invention is the provision of a rack on one part of the last and a gear operated by a long lever or handle on the other part of the last and located in the cone portion thereof, so that the handle may be readily accessible for movement to cause a sliding of the two parts of the last o-ne on the other for removing the last from the shoe.

A further object of the invention is the provision of a rack part which may be readily removed for replacement or repair.

`With these and other objects in view, the invention consists of certain novel features of construction, as Will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. l is a sectional view of the last with its movable parts located in working position.

Fig. 2 is a view similar to Fig. 1 showing the last parts relatively moved by manipulation of the mechanical contrivance for operating it.

Fig. 3 is a section View on line 3-3 of Fig. 2.

Fig. 4 is a section View on line 4-4 of Fig. 1.

Fig. 5 is a perspective view of the rack portion which is xed to one part of the last.

Shoe lasts which have heretofore been used have largely been of wood with the fore part and heel part of the last hinged together so that when the parts are moved about the hinge the last may be more readily removed from the shoe after it has been assembled about the last. Other mechanical contrivances for effecting a removal of the last from the shoe have been had, usually requiring tools or some handle insertable into the last for operating the mechanical contrivance. Metal lasts are being used lto some extent in shoes particularly in cemented shoes, and I have utilized a metal last, although of a hollow structure, which affords the required strength of support for mounting a manipulatable part of a mechanical contrivance in the cone of the last where it is readily accessible and I have utilized a metal insert or part in the other portion of the last which may cooperate with the mechanical contrivance in the cone of the last for effecting a relative movement or a contraction in size for 5 removing the last from the shoe. It will, of course, be realized that this last may be used for nailed shoes where suitable means for receiving the nails are provided, and the following is a. more detailed description of the present embodi- 10 ment of this invention, illustrating the preferred means by which these advantageous results may be accomplished.

With reference to the drawing, II) designates the fore part of the last and II the heel part l5 of the last. These are each shown as of a hollow cast-metal construction, and by suitable core holes making the inside of the last accessible for purposes as will presently appear. The cone part I2 of the last is carried by the heel part II and 20 is suitably slotted as at I3 to receive the gear I4 which is pivoted on a pin I5 passing through the opposite walls of the slot.

A handle I 6 is fixed to this gear I4 and may be swung in the slot about the pivot pin I5 as 25 a center. When the handle is so located as to cause the parts to be in their working position the handle is largely housed Within the slot I3, there being but a slight extension suitable to be engaged for its manipulation. The engaging 30 surfaces between the heel part and the fore part of the last are represented as at II and I8, which are generally in the same plane and are smooth to contact and slide one on the other.

Askeleton wall portion I9 provides a large part 35 of this surface I8 and there is provided in this wall a `groove 20 which extends from the upper portion of the fore part I0 inwardly for a length less than the length of the wall I9. This groove 2!! receives a guide member 2| which snugly fits 40 in the groove 2i! and has a rack portion 22 projecting outwardly beyond this groove, and also an undercut portion 23 which may be of dovetail or T shaped cross section as shown extending outwardly beyond this groove and beyond the 45 face I8 of the juncture between the parts I0 and l I. The member 2I is removably held in the slot 2i) by bolts 36 passing through openings 31 in the member and threaded into the wall I9 at 38 which is suitably tapped to receive these 50 bolts. The head 39 of the bolt is accessible through the core opening 40 in the fore part of the last. The hole in wall I9 for the bolt 3B is formed by drilling through the side of the last as at 4I which is afterward plugged as at 42. 55

In the heel part I I the skeleton Wall portion 24 is provided with a groove 25 which receives a channel member 26 having a bottom wall 21, side Walls 28, and inturned lips 29, thus forming the complemental part of the T shaped head 23 and receiving this head and providing a sliding connection between the fore part IU and heel part II of the last. This channel 26 is held in place in the groove 25 by suitably threaded members 30, engaging the wall 24 of the heel part of the last. 'I'his channel 25 extends but a portion of the length of the Wall and only sufficiently to permit of the desired movement. Thus there is no showing of the channel part or its insert at the bottom of the last.

The gear I4 meshes with the rack 22 in such position that when the handle is located as in Fig. l the juncture of the surfaces I1 and I 8 of the last at the bottom will be flush. In this position a latch 3| pivoted as at 32 is provided with a portion 33 to engage a suitable catch in the handle and hold the handle in the position shown in Fig. 1. This holding is assisted by the spring 34 acting on the latch 3 I, a pin 35 limits the movement of the latch in its action with the spring about the pivot 32 so as to hold it always in a position to be engaged by catch of the handle when swung over into engagement with it.

For removing the last from the shoe the latch 3| is released and while released the handle lever swung about its pivot I5 which rotates the gear I4 meshing with its rack 22 to lift the heel part or slide it relative to the fore part of the last and lift it out of the shoe. The handle is shown in a position in Fig. 2 in which the fragmental gear engages the last tooth in the rack for effecting movement. Lesser movements, however, may be permissive of suitable contraction for eiecting a removal of the last from the shoe.

The fore and heel parts of the last may be separated by removing the pin I5 and the gear I4 and sliding the fore part out of the upper side of the heel part. By reason of this arrangement different fore parts may be assembled with the same heel part for providing different size or shape lasts with a single heel part and its mechanical mechanism. The member 2I may be removed by means of the bolts 36 for repair or replaced by a similar part or variations in the particular shapes of a part such as 2I may be made without departing from the invention.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
