. JOSEPH H. POPE, OF HAMILTON,

MASSACHUSETTS, AssiGNoa TO UNITED sHon MA- CHINERY COEYORATION, OF PATERSON, NEVI JERSEY, A CORPORATION OE HEX-if LAST SUPPORT.

A plication filed Octobt'r e, 1922. Serial no. 59mm.v

1 '0 all whom-it may concern: Be it known that I, Josnrii H. Porn, a citizen of the United States, residing at Hamilton, in the county of Essex and State of Massachusetts, have invented -certain Improvements in Last Supports, of which thefollowing description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

The present invention relates to devices for supporting lasted shoes for operations upon them, as the attachment of the heels, and is more particularly concerned with the protection of the lining or other portion of the upper against being caught between the last and its support when'the lasted shoe is jacked or is put under pressure during the operation. V

()bjects of my invention are toprovide a simple, inexpensive and eflicient'protective device which will act substantially simultaneously about the entire support. These objects I attain through the employment of a continuous member surrounding the support and movable toward and from the jacked shoe thereon. Preferably, this member is expansible, being shown as in the form of a helical spring arranged for contact with the interior of the shoe. In the illustrated embodiment of the invention, the member upon which the last is supported includes relatively movable sections, between which the encircling spring is movable outwardly under their influence. This single workengaging member, wholly without other movable supports than those which it surrounds and free from pivoted connections, gives the desired continuity of, action an contact with the lining about the interior of the shoe, thrusting said lining away, uniformly in all directions, from thesuppoi't when the last is pressed into engagement with it. When the last member of the support is arranged for oscillation to better position the work for theoperations upon it, the lining protector, is best carried by the member, so that its relation to this element m and to the supported work is maintained constant.

One form which my invention may as sume appears in the accompanying drawing,

opening .Fig. 1 support or as a part of a heeling machine;

Fig. 2, being an end elevation of the jack showing, inside elevation, a lastwith portions in section on the line2 2 of Fig. 1; I N Fig. 3, a plan view of the jack-top; and Fig. 4, a vertical section therethrough on the line H of Fig. 3.

The numeral 10 designates a jack .of a heeling machine, as of the Lightning type, with its associated toe-rest 12 and the dieblock l-l, with which it cooperates. Carried at the top of the jack is a last-slide 1t), lIlOUDtGCl'tO nioveytransversely in ways 18 so that the work may be correctlypositioned beneath the die-block-openings. In the slideisformed a socket 20 adapted to receive a generally sphericalv head 22 upon a last-pin 24L 7 Furnishing the upper portion for this socket and being secured in place upon theslide by screws 26 is a plate 28, overhanging the head 22 at an opening registering with the top of the socket. The last-pin 24: is designed to enter the vertical bore Z) in the cone 0 of av last L, it giving, by virtue of its oscillationin the socket, a lateral adjustment to permit the work to conformto the pressure applied to it by the operating elements of the machine, as when the heel H which is to be attachedto the lasted shoe S is pressed against the under side of the die-block 14 preparatory to driving the heel-attaching nails, A contactprojection 33, preferably cylindrical in form, depends from the under side of the head 22, and, by its contact with the lower cylindrical portion of the socket, limits the movement of the head in the socket, and

' The last-pin carries, upon a shoulder 30 ofthe head 22, a last-bed-plate 32, which supports the crown-portion of the cone of the last, holding it againstniovenient longitudinally of the jack for the operations upon the lasted shoe. This bed-plate preferably includes two sections, the lower 34 being fast upon the head 22, and the upper 86 surrounding the pin which passes through an 38 in it, this upper section being free for limited movement along the pin. It is held against separation from the fixed plate and the extent of its movement deterjack, with its lining-protector,

mined by screws 40 passing through openings in the plate-section 34 and being threaded into the section 36. Heads 42 of these screws lie within counterbores of the plateopenings, contacting with the inner extremities thereof at the limit of upward movement. The edges of the

sections

34 and 36 adjacent to each other are inclined at 44, diverging outwardly to give a generally V-shaped depression. In this depression is located a continuous, expansible member, furnished by a helical spring 46, which is always under some tension, this drawing the spring toward the bottom of the groove and holding the bed-platesections normally separated from each other. The diameter of the convolutions of the spring is such that in this normal position, its outer side preferably projects somewhat beyond the peripheries of the plates, so that when a shoe is jacked, with the bed-platesections, as well as the last-pin, within it these curved surfaces tend to deflect the upper, with its lining, outwardly, and prevent their entrance between the bed-plate and the crown of the last.

In the operation of the machine, when pressure is applied to the lasted shoe, the movable bed-plate-section 36 is depressed, expanding the spring 46 and causing this to emerge from its depression, as best appears in Fig. 2 of the drawing. This engages the lining of the upper about the entire support, thrusting it away, not only from the juncture of the last and bed-plate, but also from the opposing surfaces of said bed-plate and the slide, placing it beyond danger of being caught thereby and mutilated. hen the pressure is removed, the spring 46 contracts to separate the bed platesections, and is thus drawn into its depression, the parts resuming their normal relation. Whatever position of self-adjustment the last-pin assumes in the operation of the machine, the bedplate and lining-protector move with it, so that the relation of the lining-engaging periphery of the spring 42 to the interior of the lasted shoe remains unaltered.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. The combination with a last-support, of a continuous lining-protector surrounding the support and movable toward and from a lasted shoe.

2. The combination with a last-support, of an expansible member suro-unding the support and arranged for contact with the interior of a lasted shoe.

3. The combination with a last-support,

of a work-engaging spring surroui'iding the support.

4. The combination with a last-support, of a helical shoe protector carried by the support and movable toward a lasted shoe.

5. The combination with a last-support, of a spring surrounding the support, and means for expanding the spring.

6. In a last-support, a last-supporting member including relatively movable sections, and a shoeengaging spring movable by the sections and independently of said sections.

7, The combination with opposite lastsupporting plates having a space between their edges, of a lining-protecting member encircling the space.

8. The combination with opposite lastsupporting plates having oppositely inclined edges relatively movable toward and from each other, of a helical spring contacting with said edges.

9. In a jack, alast-pin, a last-bedplatesection mounted in fixed relation to the pin, a bed-plate-section movable upon the fixed section, and a lining protecting member encircling the plat-es and arranged to act upon the movable section.

10. In a jack, a last-pin, a last-bedplatesection mounted in fixed relation to the pin, a bed-plate-section movable upon the fixed section, a lining-protecting member encircling the plates and arranged to act upon the movable section, said plate-sections having converging inclined edges, and a helical spring situated between said edges.

11. In a last-support, a last-pin arranged for universal movement, and a lining-pro tector carried by the pin and sharing in its universal movement.

12. In a last-support, a last-slide, a lastpin movable thereon, and a lining-protector carried by the pin, all these elements being arranged to enter a lasted shoe.

13. The combination with a jack-top having a socket, a ball movable in the socket, a last-pin projecting from the ball, a lastbed-plate carried by the pin, and a member mounted for movement upon the bed-plate and arranged to engage a lasted shoe.

14. The combination with a jack-top having a socket, a ball movable in the socket, a last-pin projecting from the ball, a last bed-plate carried by the pin and having relatively movable sections, and a workengaging spring interposed between the sections.

In testimony whereof I have name to this specification.
