Specification forming part of Letters Patent No. ESQLHQS, dated April 28, 1871i; application filed December l5. 1873:

@putting to the machine, be specially made for it. f

In lastingr'hand-made shoes by hand, the inner sole is laid on the bottom of the last, the upper drawn' over and tacked, thewelt put round, .and 'then upper welt and inner sole lunited by stitches through all. Inthis opera-` tion the lasting is doneJ before sewing, and the line of stitches is determined by the lasting.

-In my method the upper is cut by pattern 'carefully developed to the shape of the lastto lbe used. Next, a welt is attached tothe ed ge y oi.' the upper all round, except at the heel.

. This work nishcd, the shoe is ready for lasting. With an upper properly developed tothe last and eut to size, the attachment of lthe welt is very readilyjinade at the proper line by running through a stitching or riveting mechanism with the edge ot' the welt or upper against a gage. The Shoe is'thus made read?,r for lasting. A last of proper size is taken, the

upon it and adjusted in the machine.

At one end of the machine is 'a standard, A, carrying a toe-block, a, and lasting-plate b, which projects inward toward the shoe, and is to beinsertedunder the welt. At the other end is a movable Standard, I3, operated by a hand-Wheel and screw, c, and carrying a spindle or bracket, d, upon which. thel'ast C is hun g, the toc'being adjusted in the toe-block a.

This standard also carries a lastingplate, bf, to fold the upper over at the heel. rlwo jaws,

D lil, formed at the edges, in plan, to lap upon the last a moderate distance when closed alon g a line parallel to the outer conformation ofthe last, and in elevation to correspond with the curved under surface of the last, are arranged ou levers of the first order F, I, and J, which are pivoted in slots in theirame of the machine, allowing the jaws D E to be raised and lowered parallel to the sides of the last. Another lever of the iirst order, K, having arms L, which lay hold of the jaw-traine. F I J, serves to lift the jaws, and the toggles G H'with its handle m serves to' close the jaws. The two motions of the jaws, each independent of the other, enable the workman to catch and lift the welt, and with it the upper around the last, and then, by closing, catch under the welt W, as shown in Fig. 2, and draw the upper round the last to a beari ng all over, where it is tacked by hand, or by a continuous taeler,ldevised and soonrv to be patented by me.

Of'course, these independent Vertical and' horizontal motions of the jawsl) ll can bc produced 1n various ways, the one l have indicated being thomost obvious..

-Iclaiin as my invention and desire to secure s by Letters Patenty u j 1.,The arrangement. of lasting-plates D and E, upon jaws, which have a Vertical movement parallel'to the sidesof-fthe last, substantially as described.
