' s aifit'aioi. mining t e of Letters Patent No. 173.405. dated February 15, 12516; application filed March 10,l.875. I

Toull whom itnlag CMLOGTflf i 7 Be it known that I, JESSE W. HATCH, of the city of Rochester, in the county ot' Monroe and State of New York, have inventeda certain new and useful Improvement in Lasting the Heels and Toes (either or both) of Boots and Shoes, and the apparatus for accomplish- .ing the same,of which the. following is a speciily tacked, the effect being to form better seat or bend to theupper for the fitting of the sole. at the heel and toe, as will appear here- 'inafter.

In the drawings,Figure 1 is-aplan of a boot with its heel presented to the crimping-jaws for lasting, showing also the machine; Fig. 2, a side elevation ofthe same; Fig. 3, a similar view to Fig. 2, but showing the toe of the boot presented to the jaws instead of the heel; Fig. 4:, a plan of the toe-rest and its lever removed A represents a boot or shoe with the upper I applied upon the last B in condition for crimping the heel or toe, to allow the outer sole to be fitted.

The upper is first drawn over the last in the ordinary way by hand, and the edges tacked to the insole at the sides by two or three tacks,

to secure the parts together. The last is then placed on a suitable support, and the heel or toe presented in'proper position to the action of the crimping-jaws G O, or equivalent devices, which slide closely over the edges of the upper, and turn them down and crimp them in place closely-to the insole, so that they may be secured by tacks. The jaws or equivalent g are so arranged as to draw in upon all sides, 4 thereby leaving theaseat a or the rounded portion of the upper where the outer sole joinsper- ,fectlysmooth, the wrinkles or crimps all being drawn into the inner edge, as shown at b. The jaws may be provided with notches or holes 0 c at their inner edges for the reception of the tacks, that pass through into the leather. In the drawing, D is a table or bed, on top of which the crimping-jaws 0 G are mounted.

The jaws have shanks .0 G with pivots (Z d at their ends, which rest in slots fof the table, having. such curvation as will causeithe jaws to close properly upon the leather as they are thrown forward. .The central pivot g. of the jaws is connected with a pitman,'E, which may receive its motion from a hand-lever, G, or from any automatic power desired. As this lever is drawn forward the jaws close upon the leather properly.

F is a vertical support, having a. horizontal arm, vi, which passes through a bearing in the bed, so as to be moved out or in, and it is secured in any position by a cam,-J, or equivalent. At its lower end the support has two horizontal bearings, k it, through which passes the standard H, that supports; the last. The

lower end of the standard is cut with a screwthread, and is provided with a nut, l, by which the standard is adjusted higher or lower, to enable either the heel or the toe of the boot to be presented to the crimping-jaws by reversing it.

The upper end of the standard has a jointpiece, H pivoted at m, and kept stifi' by a spring, n. This is for the purpose of allowing the last to be turned or inclined back, as in Fig. 3, when the toe is presented to the crimping-jaws, so that the toe will lie flat or in line .for the jaws to pass over. The last is simply swivele'd on the end of the joint-piece,'so that it can swing around, and it is held firmly by the hand of the operator while the crimping action is performed.

K is a. toe-rest, which slides in and out horizontally, being operated by means of a lever, L, which is held in any position by means of a lug and notches, p p, or any equivalent arrangement. This toe-rest is used only when the toe of the boot or shoe is being lasted, in

which case it is thrown out, as shown inFig. 3, and supports the front of the last under the pressure of the crimping-jaws. When the heel is being crimped it is thrown back, as shown in Fig. 2.

From the above description the operation of i The passage and closing in of the crimp the toes.

for this purpose, as it bendsb'ack to bring the surface of the toe in line with the crimpingjaws. i It is obvious that the heels and toes may he lasted alternately in the same manner, and the whole finished without removing the boot or. shoe from the standard .till complete. In large manufiactories it may bedesirable to use separate machines for lasting the heels and toes.
