IMPROVEMENTIN LAsTs.

Specification forming part of Letters Patent N 0. 177,192, dated May 9, 1876.; application filed' t April 5, 1876.

Y of two lasts provided with my invention applied to each, the locking-plate and mouthgroove in one case being fixed to the insteppiece, and in the other to the body portion, of the last. Fig. 3 is a top `viewof the body portion, and Fig. 4 a bott-om view of the instep-piece, of the last, in which the lockingplate is attached to the movable insteppiece. Fig. 5 is a top view ofthe body portion, and Fig. 6l a bottomview of the instep-piece,

of alast in which the locking-plate is attached to the body portion.

The object of my invention is to preserve the instep-piece in its normal position, or prevent it from accidentally Slipping back in the body part, while the last may be in a shoe.

I amv aware that an instep-piece has been made with a dovetailed stud or a tongue dovetailed in section to enter a correspondingly-shaped straight groove made in the body part of the last, and therefore I do not claim such.

I am also aware that, instead Of the straight dovetailed groove, a metallic plate having a straight slot in it has been used, there being to the instep-piece a headed stud or screw to enter such groove, all being as shown in the United States Patent No.

These modes of connecting the last-body and instep-piece differ from mine, in the groove or slot being straight and not rightangular. My invention not only holds the instep-piece down in place, but prevents it from accidentally working back on the lastbody, during the process of making a shoe on the last. A v

In carrying out my invention I make use of a metallic plate, A, having a right-angular groove or slot, B, made in it, fromv and to Open out of one end of it,.in' the manner as shown, and such plate I fasten, byscrews or other means, either to the' movable instepframe C or to the body part D of a last, in

which case I arrange the plate with'its opening in reference to such parts. in manner as represented, and so that its slot shall come over or partially cover, in manner as shown, a tapering frame, E, made in the part G'or'D, to which the plate may be fastened.. With such right-angular slotted plate I employ a screw or stud, F, provided with a head larger in diameter than the shank, and this screw or stud I arrange in the body part D, in case of the plateA being fixed to the insteppiece; or, whenA the Said plate A is fixed to the body part D, Il arrange the screw or stud in the instep-piece, the arrangement either way being as represented in the drawings.

I prefer to provide the instep-piece, at its y -its inclined surface fto the abutment c,

and next moved laterally, 'so as to carry the shank of the Screw or headed stud F into the lateral portion cl of the right-angular groove of the locking-plate. This latter part of the groove, (so-operating with Y the screw or stud, will prevent the instep-piece from Starting or slipping backward. In Order to remove the instep-piece from the body of the last, such instep-piece has tirst to be moved a littlev sidewise, until the stud may enter the main portion e of the'lslot B. This having taken place, the instep-piece may be drawn backward and OE the body part.

I claim- A 1. In combination with a last-body, D, and

v its movable nstepfpiece G, the headed Stud and Ae. locking-plate, A, provided withan or screw F and the locking-plate A, having open and angular groove, B,a.l1` being substaen-` the open and angulanslot B, all being esseu-` tially as Set forth.

tially as shown and described. JOHN M. BARNETT. 2. In combination with a last-body, D, and Witnesses: f its movable instep-piece, C, a headed stud R. H. EDDY, or screw, F, an open channel or groove, E, J. R. SNOW.
