SHOE-LAST.

Specification of Letters Patent. patentgd D 1915.

Application filed July 13, 1914. Serial No. 850,792.

To all whom it may concern:

Be it known that I, ANDREW R. ANDER- SON, citizen of the United States, residing at North Arlington, in the county of Hudson and'State of New Jersey, have'invented certain new and useful Improvements in Shoe- Lasts, of which the following is a specification. I

This invention relates to shoe lasts.

The ordinary last is either formed in one piece, or it embodies a hinged heel section, and after the shoe has been formed upon the last and it is desired to remove the shoe it is, in the use of such a last,"necessary to exert considerable force in order to pull the shoe from the last and in disengaging the heel of the shoe from the last the shoe must be bent back at the instep of the shoe which is liable to result in the shoe becoming torn or otherwise marred.

It is therefore an aim of the present. invention to provide a shoe last so constructed that a shoe formed thereon may be readily and quickly removed from the last when desired, the last embodying a heel. section which is movable to recede from the heel of the shoe whereby .to clear the heel to permit a means for locking the sections comprising the last so that the last will be rigid while the shoe is being formed thereon, the means provided being adapted to not only hold the sections againstrelative sliding movement upon each other but also to draw the sections together so that there will be no loose .play.

In .the accompanying drawings: is a side elevation of the last embodying the present invention in. working condition. Fig. 2 is a similar view, illustrating the sections of the last relatively displaced so as to permit of the shoe formed thereon being removed from the last. Fig. 3 is a detail vertical front to rear sectional view, illustrating the locking means for holding the sections of the last'against relative move?- ment. Fig. 4 is a sectionin a plane at right angles to the plane of Fig. 3. Fig. 5 is a detail view illustrating the locking post and plate in position to permit of the ast sections being relatively moved. Fig. 6 is a similar view but illustrating the parts 1n locking position. Fig. '7 is a perspective place by means of'tran'sverse Figure 1 view of the locking plate. Fig. 8 isa perspective view of the locking post.

Corresponding and like parts are referred v and the heel section by the numeral 2. The

body section 1 is provided with an oblique or inclined rear end face 3 and the heel section2 is provided with a correspondingly inclined forward end face at. For the purpose of slidably connecting the sections 1 and 2 with each other and with their faces 3 and 4 in contact, as shown in Figs. 1 and 2, the

rear end face of the section 1 is formed with *a' slot 5 in which is fitted a combined locking and guide plate 6, the plate being held in ins 7 fitted through the rear end portion 0 the last section-and through the openings in the said plate. The .plate projects through the said rear end face of the section 1 and into a slot 8 formed in the forward face of the heel section 2, the projecting portion of the plate being slidably received within the said slot.

The said projecting portion of the plate is formed with a longitudinally extendin slot 9 and'transverse pins 10 are fitte through the forward portion of the heel section 2 .and project through the said slot 9. In this manner the sections 1 and 2 are connected for limited relative sliding movement but are held against separation. Referring. now to Figs. 1 and 2 of the drawolination of the contacting faces 3 andfl of the sections 1 and 2, the sections may be relatively displaced either by moving the toe section upwardly or the heel section downings, it will be apparent that due to the inwardly, as shown in Fig.2. The heel section will recede from the heel of'the shoe, 4 being formed upon the last and consequently will clear the heel of the shoe thereby permitting of-the shoe being readily slipped-off from the body or toe section 1. Moreover, it will' be apparent that the last is in effect considerably shortened when its sections are relatively displaced. In order to hold the sections in the position shown in Fig. 1 of the drawings, there is provided a locking-device which Will now be described.

The locking device includes a locking with a circumscribing groove 13 and the wall of the barrel being struck in, as at 1d,

to form portions seating in this groove and thereby holding thepost against accidental displacement within the barrel although not interfering in any way with its rotative' movement.

In order that the post may be rotated, it is provided at its outer end with a flattened head or bit 15 for the engagement of a suitable wrench or key for the purpose stated. The inner end of the barrel 11 terminates at the bottom of the slot 8 and the locking post 12 beyond this end of the barrel, is reduced in diameter, as indicated at 16, and has its reduced end formed with a diametrically extending notch 17 of a width slightly greater than the thickness of the projecting portion of the plate 6. The reduced portion 16 of the locking post is formed with a single thread 18, which is of courseinterrupted at the ends of the-notch 17. The locking plate 6 is formed in the edge of its'projecting portion with a notch 19, the side walls of which are formed with substantially V-shaped notches 20, so located as to receive the thread 18 when the locking post is rotated. By reference to Figs. 4:, 5 and 6 of the drawings, it will be observed that in one position of the locking post, the notch 17 occupies the same posi-.

tion as the edgeof the projecting portion of the locking plate, and in this position of the post, the sections 1 and 2 may have relative sliding movement. When it is desired, however, to lock the sections in the relative position shown in Fig. 1, the post 12 is given a quarter turn so that the notch will be disposed transversely of the line of extent of the edge of the projecting portion ofthe locking plate, the post,at such time, having its reduced end projecting into the notch 19. Upon such rotative movement of the post, the thread 18 will ride in the notches 20 and not only will the section 2.be held against sliding movement with respect to the section 1 of the projecting portion of the locking plate as a guide, but the section 2 will be drawn firmly against the section 1 due to the cam action of the thread 18.

From the foregoing description of'the invention, it will be apparentthat the sections comprising the last may be securely and firmly locked together in the relative position shown in Fig. 1 during the operation of forming the shoe of the last and that when it is deslred to remove the shoe from the last, this may be readily accomplished by rotating the post 12 to' the positionfrom the heel of the shoe.

shown in Figs. 4 and '5- of the drawings, whereupon the sections may be relatively displaced, the section 2, in such manipulation of the sections, being caused to recede to shorten the length of the last, and means for holding the sections against relative movement and for drawing the sections together.

3. In a last, a body section, a heel section, the said sections having contacting oblique faces, a locking plate carried by one of the sections and projecting slidably into the other section, the said plate in its projecting portion being provided with a notch, and a locking post carried by the last-mentioned section and having a portion arranged to seat within the notch, the said portion being.

provided with a notch to slidably receive the projecting portion of the plate in one position of the post.

d. In a last, a body section, a heel section, the said sections having contacting oblique faces, a locking plate carried by one of the sections and projecting slidably into the other section, the said plate in its projecting portion being provided with a notch, and a locking post carried by the last-mentioned section and having a portion arranged to seat within the notch, the said portion being provided with a notch to slidably receive the projecting portion of the plate in one position of the post, the walls of the notch in the plate being formed with notches and the said portion of the post being provided with a cam portion to engage in the said notches.

5. In a last, a body section, a heel section, the said sections having contacting oblique faces, a locking plate carried by one of the sections and projecting slidably into the other-section, the said plate in its projecting portion being provided with a notch, and a locking'post carried by the last-mentioned section and having a portion arranged to seat within the notch, the said portion being provided with a notch to slidably receive the projecting portion of the plate in one position of the post, the walls of the notch in the plate being formed with notches, and the said portion of the post. being provided with a thread to engage in the said notches.

6.'In a last, a body section, a heel section, the sections having oblique contacting faces; a plate carried by one of the sections and slid-ably fitting within the other section and being formed with a slot, a pin secured transversely through the last-mentioned section and extending through the slot in the plate whereby to connect the sections for relative sliding movement and to limit such movement, the projecting portion of the plate being formed With a notch, and a looking post rotatably mounted in the second mentioned section and arranged to project into the notch whereby to hold the sections against relative sliding movement, the said portion of the post having a notch and being rotatable to position its said notch to slid- 15 ably receive the projecting portion of the plate. l

In testimony whereof I afiix my signature in presence of two witnesses.
