LAST.

SPECIFICATION forming part of Letters Patent No. 291,991, dated January 15, 1884,

Application filed August 6, i883.

To aZZ whom, it may concern..-

Be it known that I, GEORGE WV. DAY, of Haverhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Lasts for Boots and Shoes, of which the following is a full, clear, and exact description.

This invention relates to lasts more particularly intended for use in the manufacture of machine-sewed boots and shoes, and to lasts having their bottom faces surrounded by anarrow metallic rib or plate, against which to drive the lasting-tacks in lasting a boot or shoe upon the last.

The invention consists in a construction, first, of the surface of said rib, against which the lasting-tacks are driven, and of the por tion of the bottom face of the last for its whole width and length between said rib, and also, especially at the toe portion thereof, in combination with a beveling of the rib which crosses said toe portion at its inner edge, all substantially as hereinafter described, reference being had to the accompanying plate of drawings, in which- Figure 1 isaplan view of bottom face of the last. Fig. 2 is a vertical longitudinal section on line 2 2, Fig. 1. Fig. 3 is a longitudinal sectional view,illustrating the last at its toe in connection with the toe portion of the shoe after the last has been drawn partially from its position in lasting the shoe, but before being wholly removed. Fig. 4 is a vertical crosssection on line a 4., Fig. 2.

In the drawings, A is a last, made in two parts, B and G, and the line a of split runs from the usual point, 1), near the ankle, toward the toe, but not fully to the toe, as shown at d, Fig. 2. Y

D is a narrow metal rib or plate,which surrounds the bottom face of the last and corresponds to the shape thereof, and is attached by screws or other suitable fastening means passed through it and entered into the last. This rib or plate D is widened or broadened at f, to cover, substantially,the whole bottom surface of the heel portion of the last, and the remaining portion,E, of the bottom face of the last, to wit-the shank, ball, and toe--is cut out or recessed out between the inner edges, 9, of said rib for its whole width and length. (See Figsl, 2, and l more particularly.) The depth (No model.)

of the recess E in the bottom surface of the shank is greater than in the ball and toe portions, but in all portions it inclines or bevels from the inner edge, g, of the rib D, toward the central portion of the bottom surface. (See Fig. at more particularly.) This recessing of the bottom surface of the last for the whole width and length, and of an increased depth in the shank,the better disposes of the turnedback channeling lip or flap F of the channeled inner sole, G, in using the last for lasting a boot or shoe having an inner sole channeled, and consequently the metal rib D of the last can be the better seated upon and against the channel of the inner sole, which by turning back the lip or flap thereof is uncovered for such purpose. At the portion h of the rib D, crossing the toe of the last, the rib is widened, as shown at Z, and made inwardly beveling, and the beveling is continued in an inward beveling of the bottom surface, as shown at m, Figs. 2 and 3, all of which renders the last capable of being drawn with the greatest ease 7 5 and facility over the turned-back lip or flap F at the toe of the inner sole, G, (shown in Fig. 3,)when thelast is to be with drawn, previously having, as usual, removed the instep part 0 of the last. The widening of the rib at the too is to provide for the beveling surface m inside of the rib portion, to preserve the full width of the rib at the toe for the riveting of the tacks,

as described 5 and to facilitate the removal of the last from the boot or shoe, the channel a of 8 5 the inner sole at the toeis preferably increased in its width, as shown, which forms in part the subject of a separate application for Letters Patent of the United States of even date herewith.

p in Figs. 1, 2, 3, and 4 is a groove made in and surrounding the bottom face of the rib D of the last, and in aline corresponding, substantially,to that along which the lasting-tacks are to be driven to last the boot or shoe. This 95 groove forms a seat, as it were,for receiving and riveting the tacks as they are driven,and it acts as a guard to prevent the tacks as they are driven and riveted from passing to and over the inner edge, 9, of the rib D, and con- 10o sequently insures their being riveted against the rib, as is desired and intended.

Having thus described my invention, what I claim is 1. A boot or shoe last having the center porrounding its recessed bottom surface, and havtion of the bottom surface recessed or deing its toe portion widened andinwardlybevpressed, as shown, and the outer edge proeled thereat, substantially as and for the pur- 1 vided with a metallic rib, 1), all substantially pose specified.

5 as and for the purpose set forth. In testimony whereof I have hereunto set my 2. A boot or shoe last having the center porhand in the presence of two subscribing wittion of the bottom surface recessed or denesses. pressed as shown, and the outer edge provided T with a metallic lib, D, having the shallow I GEORGE DAL :0 groove 11, all substantially as and for the puri pose set forth.
