LAST.

SPECIFICATION forming part of Letters Patent No. 752,317, dated February 16, 1904.

Application filed October 12, 1901- Serial No. 78,406. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM J; WEIR, of

-New York, in the county of New York and drawings, in which heel part.

Figure 1 is a longitudinal section of my new last. Fig. 2 is a planview, partly in section. Fig. 8 is a perspective view of the heel part.

My new last is a hollow divided last and is especially useful as a filler and shoe-tree for the use of shoe salesmen. Hollow lasts for such purposes have been heretofore employed, it being obviously necessary that suh a last should be as light as possible consistent with reasonable durability. Furthermore, in the production of this new last I employ a new method of manufacture which results in a last which is entirely novel in its details of construction. While hollow lasts have been heretofore known, such a last as I have produced was never before known, for not only is it hollow and divided, but it is also divided in a pcculiar way, as a result of which its strength is -enormously increased and the two parts of which it is made up are also organized and associated together in such a. fashion that while the dividing-line between the two parts of which the last is made up is perpendicular to the longitudinal axis of the last the heel part swings clear of the forward part when the heel part is lifted on its hinge.

Referring to the drawings, A is the hollow toe part of the last at the rear end, and upon the inner side are two bosses at a upon the opposite inner surfaces, for a purpose to be hereafter explained.

B is the hollow heel part, having upon its forward end a projecting part 6. This part B while hollow, has walls upon four sidesviz., the front wall, carrying the projection b, the two side walls, and the rear end wall.

In its best form the heel part of my new last is formed of one continuous and integral piece of wood or-other suitable material and the part- 6 is also integral with the front wall of the The bosses a; a are also integral with the walls of the toe part and extend toward one another, the spacedividingthe inner faces of these bosses being equal to the thickness of the part 6 plus a slight allowance for clearance. These bosses, it will be observed, are near the upper edge of the walls to which they are fixed, and the part extends from the upper edge of the wall to which it is fixed and is shaped and proportioned to pass between the two bosses. The part 5 being passed between the two bosses in the proper position, a hingepin w is passed from one side of the last to the other, passing through and connecting the bosses and the part b. The result of this organization is that while the division of the last is eflected on a line perpendicular to the longitudinal axis the heel part, swinging upon a center eccentrically placed, swings clear of the fore part in operation.

In making my new last I employ a new method, which has results of economy of material and labor and which automatically,

forms the working parts of the last in their important dimensions to give the necessary close fit. This method consists in sawing a last into two parts by a out which separates the heel part from the toe part, leaving a projection 6 upon the forward end, and by the same movement forms a corresponding slot in the'rear end of the toe part within which the part b can work, the material removed by the kerf of the saw leaving asufiicient clearance to insure easy motion notwithstanding variations of temperature and humidity,while the fit of the parts is sufliciently close to insure against undue looseness in the connection.

The forming of the hinge-piece b integral with heel part B is an important feature of my invention, since it would be impracticable or at least highly undesirable to secure the hingepiece to a hollow heel-piece both because of the intrinsic difficulty of securing a hinge-piece,

which is subjected to considerable wrenching blocks of material which when shaped may be fitted together and assembled; but it is obvious that this method of manufacture, involving as it does the turning of two separate parts in two distinct operations and the subsequent fitting of these parts together, is inferior to the method above described of sepa rating an ordinary last into two parts in such a fashion that the fitting is done by the dividing operation, thus saving one turning operationthe fitting operation-and, finally, also eflecting a saving of material.

I 'claim.

1. The hollow divided last above described, made up of a hollow toe part; a hollow heel part having a wall across its forward end and a projecting hinge member, integral with and projecting forward from the front wall of the heel part within the rear of the hollow toe part and connected therewith by a pin.

2. The hollow divided last above described,

made up of a hollow toe part having opposed bosses upon its interior rear walls; a hollow heel part having a wall across its forward end and a projecting hinge member integral with and projecting forward from the front wall of the heel part between. the opposed bosses and a pin passing through the bosses and the forward end of the hinge member.

3. The hollow divided last above described, made up of a hollow toe part having opposed bosses near the upper edge of its interior rear walls; a hollow heel part; a wall across its forward end and a projecting hinge member integral with and projecting forward from the upper edge of the front wall of the heel part between the opposed bosses and a pin passing through, the bosses and the forward end of the hinge member.
