A. SBICCA LAST FOR SHOEMAKING Filed April 27, 1940 INVENTOR Art/ear Jz'cca ATTORNEY Patented Feb. 10, 1942 UNHTXD {S T 2 Claims.

My invention relates to shoemaking.

The object of my invention is to provide a last, the use of which will enable shoemakers to make shoes which will fit the feet of a wearer in a more perfect manner.

The principal object of my invention is to provide a last for use in making womens shoes of the type known as opera pump Oxfords, etc., by means of which the shoes may be made to fit more perfectly around the heel of the wearer and to prevent gaping at the waistline of the shoes in the act of Walking.

A further object is to provide lasts for the purpose stated which may be made at less cost than heretofore.

A further object is to provide a last upon which a shoe upper may be placed in such a manner as to permit it to be held without the use of tacks, and movable relative to the last prior to affixing the sole to the lower margins of the upper, and also to space the upper edges of the upper at a predetermined distance apart to insure a close fit on the foot of a wearer and eliminate a gaping action in the act of walking.

A further object is to provide an articulated last by means of which a shoe having an exceptionally long vamp may be removed from the last without danger of injury to the shoe in the act of removal.

At the present time lasts are used which extend higher than the uppers mounted thereon in the process of making the type of shoes referred to and therefore the upper side rim portions of the shoes are separated from each other a distance corresponding to the width of the last along the line of the rim.

By the use of the last now to be described, the uppers may be closely drawn together and fitted over the last, as illustrated, and thereafter drawn firmly into form and the soles attached in the usual manner of making such shoes.

Referring to the drawing which forms a part of the specification:

Fig. 1 is a side elevational view of a last formed in accordance with my invention and shown as when made in a single piece of wood.

Fig. 2 is a side elevational view of a last, shown partly in section to disclose the construction of the new last when made in two parts connected in articulated relation.

Fig. 3 is a plan View showing a shoe upper placed on a last, the form of the last being illustrated in dotted lines.

Fig. 4 is a perspective view of an upper mounted on a last, and illustrating the closeness of the top edge portions of the upper adjacent the heel, the last being indicated in dotted lines.

Fig. 5 is a cross sectional View of the construction shown in Fig. 2 on line 5-5 thereof.

l9 indicates the body of the last, which is usually made of wood, and II) the tubular thimble which fits over a pintle support for the last in the usual manner.

As illustrated in Fig. 5, I prefer to make the top of the last of narrow width and the sides curved so that the upper will conform to the shape of the last and embrace the foot in such a manner as to prevent gaping of the shoe when worn; also to prevent the sides of the heel of the wearer from slipping in the shoe, even though the heel be exceptionally narrow in width.

It will be seen that the last does not extend above the means used for holding the upper edges of the upper in connected relation. and that the upper edges of the upper are held in connected relation by sewing H which extends thru the extended edge portions of the lining 2 to hold them closely together, or at a predetermined spaced distance whereby the finished shoe will present the edge portions in the required spaced relation.

The dotted lines l3l'3 respectively, shown in Fig. 3, indicate the width of the last between them, but this width may vary to provide shoes the upper edges of which may be of any desired form and spaced to provide a proper fit to the foot of a wearer, as will be readily understood by those skilled in this art.

Where a shoe is to be made comprising an exceptionally long vamp, I prefer to make the last in two portions held in articulated relation as illustrated in Fig. 2.

In making the articulated last, a slot I4 is formed in the waist portion of the last, and a slot 15 in the heel portion, both slots being narrow and located at one side of the median line thru the length of the last.

A link I6 is hinged at I! and [8 on transversely extending pins l9, and the last is divided on the oblique line 20, thus permitting the forward portion of the last to be lifted and swung a predetermined distance from under the vamp of a shoe and thereafter the heel portion of the last lifted by means of the latch 2!, from the shoe.

The latch 2! is attached in hinged relation with the forward end of the last and extends over a transversely extending pin 22 in hooked relation as illustrated.

The latch 2| also serves as a handle to lift the last from the shoe.

It will be understood that the adjacent edges of the upper are sewn or otherwise connected together prior to being placed on the last, and that thereafter the sole is attached to the upper while on the last in the usual manner.

It will be seen that the last is formed to provide a substantially straight long top portion which extends from the heel to the vamp, but the top may be curved to conform to the design of the rim portion of the pump if said rim is to have a curved form instead of substantially straight side edges.

The last permits the upper to be moved or shifted in the act of lasting to insure the opposite side rims to be of equal height when the shoe is finished.

The form of the last also permits both sides of the upper to be visible at one time, when viewed from the top, and adjusted in perfect position in the act of lasting, without the necessity of measuring to insure equal heights.

In shoe manufacturing a great number of lasts are required that are duplicates of each other, and the saving effected in the cost of turning the lasts and also the saving of material, result in a substantial saving in the cost of making, also that the space required for storage is reduced, as also the weight of the last.

To those skilled in the art of shoe manufacturing the above disclosure of the invention will be clear and the advantages thereof well understood.

Having thus described my invention, I claim as new:

1. A last for making shoes of the pump type, having an upwardly extending long narrow straight top at the waist portion, at approximately the height of the upper edge of a shoe of conventional pump type and of approximately the length of the upper edge of such a shoe; whereby said last is adapted to support the adjacent sides of such an' upper when connected together along a substantial portion of their upper edges and placed thereon in the act of lasting a shoe.

2. A last for making shoes of the pump type,

having opposite side walls converging near the top to form an upwardly extending long low wall of narrow cross section and having a narrow flat top surface to support adjacent edges of a shoe upper of conventional pump type secured together substantially throughout the length of said edges, extending longitudinally thereof from the vamp to the heel portion of the last, and of a height approximately that of such a shoe upper, substantially thruout its length.
