Specification 61' Letters Patent.

Application filed January 12, 1912. Serial N 0. 670,875.

State of Massachusetts, have invented certain Improvements in Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the draw- ,ings indicating like parts in the several figures. V

This invention relates to lasts.

More particularly it relates to that type of lasts which are provided with sole re- ,taining prongs arranged to be projected through the bottom of the last or to be retracted within the last.

The invention has among its objects to provide a last of this type with improved means for moving the sole retaining prongs and to provide means for holding the prongs 1n predetermined positions.

I To the accomplishment of these objects one feature of the present invention contemplates the provision, in a last provided with a forepart and a heelpart relatlvely movable to extend and collapse the last, and sole' retaining means comprising prongs arranged to be forced into the sole, of means for operating said prongs through the relative movement of the fore and heel parts. The specific manner in which the sole retaining prongs are operated by the relative movement of the fore and heel parts may be varied as found desirable or expedient. It is usually desirable, however, to so move the sole retaining prongs that they are projected through the bottom of the last when the last is extended and are withdrawn into re tracted position within the last when the last is collapsed.

A further feature of the invention con templates the provision, in a last provided with sole retaining prongs mounted within the last for movement into projected or retracted positions, and means for moving the prongs, of means for locking the prongs against movement when they are withdrawn in contact. the prongs in their projected positions, thus avoiding any likelihood of their being withdrawn from the sole except at the will. of the operator.

Broadly considered the invention contemplates the use of any suitable form of looking means for the sole retaining prongs; but in the construction illustrated herewith the prongs may be positively locked from movement away from either their projected or retracted positions by a latch arranged to lock the last either in its extended or collapsed condition. I

The invention also is directed to novel supporting means for the sole retaining prongs and to other features that will be hereinafter described and claimed.

In the accompanying drawings, Figure l is a bottom view of a last embodying the features of the invention in the best form at present devised; Fig. 2 is a side elevation of the last,partly in longitudinal section on the line 2-2, Fig. 1; and Fig. 3 isa view similar to that of Fig. 2, but showing the position of the parts when the last is collapsed.

In the embodiment of the invention illustrated in the drawing a forepart 1 is connected by a hinge 2 to a heelpart 3 so that the heelpart may move on the forepart to extend or collapse the last. the forepart is bored vertically and coun tel-sunk to provide holes for hollow cylindrical socket pieces 4 and 5 that are secured to the forepart by screws 6 which clamp peripheral flanged plates 7 and Srespectively on the sockets at and 5, to shoulders 9 formed by the countersink. These sockets intersect a bore 10 which extendslongitudinally from the forepart vertical wall to a point adjacent to the toe, and the sockets serve to strengthen the portion of the forepart that is weakened by the removal of the wood. A cylindrical pin 11 provided with a sole retaining prong 12 is arranged to be. moved through an opening '13 formed in the socket 4 into a position wherein the prong is projected through an opening in the plate 7, and the head of the pin 11 abuts against an overhanging wall 14: of the socket. In 'or-' der that the pin may tilt in the socket to permit its introduction and removal the socket is provided withan inclined wall 15 beneath the opening 13/ The socket 5 is similarly provided with an'inclined wall 16, and with The bottom of It is further proposed to lock i verse pin 25 carried by the heelpart.

an opening 17 to facilitate the introduction into and removed from the socket of a cylindrical pin 18 provided with a sole retaining prong 19.

The pin 11 is pivoted. between the arms formed near the end of a slide 20 mounted to slide in the bore through a slot 21 formed in the socket The slide is frictionally held in position in the bore 10 by a spring 22 arranged on the floor of the bore to engage the bottom of the slide. The pin 18 is pivoted at 23 intermediate the ends of the slide. The other end of the slide is pivoted to a link 2% which is pivoted on a trans )V this construction when the heelpart is swung upward to collapse the last the prongs are simultaneously retracted within the last and when the heelpart is swung downward to extend the last the prongs are simultaneously projected from the last and forced into an insole held against the bottom of the last. The heelpart is also bored vertically and countersunk to provide a hole for a socket 26 having an inclined wall 27 and an. overhanging wall 28. This socket is provided with a peripheral. flange 29 which rests on the shoulders formed by the countersink and is secured to the heelpart by the anvil plate 30 which covers the flange 29. The socket is prevented from turning in the hole by a pin 31. A cylindrical pin 32 provided with a sole retaining prong 33 is mounted for movement through an opening 31 into and out of the socket 26. The pin 32 is pivoted between two arms formed on a link 35 which is mounted to slide through a bore 36 in the heelpart. The link 35 is pivoted on a transverse pin 37 carried by the forepart. By

this construction the prong 33 is forced .into

the sole and withdrawn therefrom simultaneously with the similar movements of the' prongs 12 and 19. Pressure exerted upon the face of the sole during the various shoe making operations will not disturb the prongs, since the prongs 12 and 33 are held against individual movement under pressure exerted upon their protruding points by'the overhanging walls 14: and 28, which engage the heads of the pins 11 and 32; and the prong 19 also is held against individual movement by its connection with the slide 20, which is supported to resist such pressure by the wall it and the upper surface of the bore 10.

In order to prevent the prongs from being retracted within the last when the latter is in use, the heelpart carries a pivoted latch 38 one end of which rests upon a coiled spring 39 mounted in a recess 4-0 in the cone of the last, and the other end of which wedges against a pin 41 on the forepart- The parts are so proportioned and the end of the latch is so shaped that when the heelpart is moved to extend the last the spring 39 automatically wedges the latch against the pin 41. To release the latch so that the last may be collapsed and the prongs with.- drawn the spring pressed end of the latch is depressed to free the other end of the latch from the pin 41. In order that the prongs may be maintained retracted within the last when the last is not in use, the latch provided, intermediate its wedge end and the pivot, with a notch 42 which when the last is collapsed hooks over the pin 41 and locks the parts of the last against movement.
