UNITED STATES PATENT OEEICE.

A. S. MCINTIRE AND NATHANIEL STEVENS THOMPSON, OF STONEHAM,

MASSACHUSETTS.

vTOE-PIECE FOR LASTING-MACHINES.

Specification forming part of Letters Patent No. 46,375, dated February 14, 1865.

T0 all whom it may concern:

Be it known that we, ABRAM SHELDON Mo- INTIRE and NATHANIEL STEVENS THOMP- SON, both of Stoneham, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Method of Making a Toe-Piece for Lasting-Machines; and we do hereby declare that the following-is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of our invention consists in the peculiar method of forming the toe-piece (which is done by using` a part ofthe machine and an unfinished shoe on the last for a mold) of gutta-percha or some similar substance in a pliable state, which becomes hard and but slightly elastic after taking the form of the toe of the shoe. By this method a toepiece is formed which of necessity makes a perfect lit, and consequent-ly will not injure the leather by tearing or bruising, and can be made by any workman in one-tenth the time required to make the'ordinary toe-piece.

To enableothers skilled in the art to make and use our invention, We will proceed to describe its construction and operation.l

The drawing on Sheet No. l is a perspective view of the Working model for molding the toe-piece. It is not intended that this model should represent in any other than a general' manner a machine for making our toe-piece, as we can readily mold the toe-piece Without the aid ot any other machine than the ordinary lasting machine and a lasted shoe, as shown on photograph, Sheet N o. 2.

In the following description similar letters refer to similar parts.

Drepresents a lasted shoe.

the movement of which the toe of the shoe is lasted.

B represents a socket for holding the heel of' shoe, or that part of the lasting-machine by the movement of which the heel of the shoe is lasted; A, base or body of machine.

To mold a 'toe-piece we proceed in the following manner: The heel ofa lasted shoe is placed in the socket B, the head-piece O is drawn away from the toe, and the guttapercha, or other similar substance of which we propose to make the toe-piece, is placed in the socketF in apliable state. Then the headpiece is moved up firmly against the lasted shoe and is held or secured in position until the material hardens. Thelasted shoe is then removed, and the toe-piece is ready for use.

In practice we find it best. to use the lasting-machine itself for a mold. In this case the lasted shoe is placed in position, the jaw C is drawn out by means of the hand-screw, and the material placed in the socket for the toe-l piece. The jaw is then screwed up so that the pliable material .will be pressed firmly against the toe of the shoe and held in position until the material hardens. The lasted shoe is removed, and the toepiece is ready for use.

What we claim as our invention, and desire to secure by Letters Patent, is-

The method of forming a toe-piece for lasting-machines of any suitable material by meansoi' the lasted shoeand the jaw of the p lasting-machine, substantially and for the purpose as herein described.
