IMPROVEMENT IN DIES FOR CUTTING THE UPPERS OF BOOTS AND SHOES.

Specification forming part of Letters Patent N 0. 212,13 1, dated February 11, 1879; application filed October 18, 1878.

The diaphragm is further'provided with off work a nice adjustment is not possible un- It will readily be seen that the diaphragm having thus been cut and provided with the serrated edge (1 and the indentations or lapguides d, are then united in the regular way. The edge of the quarter lapping upon the vamp to the lapguide, conforming to it its entire length,but notextendin g over the same, is then ready for the lasting process. The upper being thus,it may be said, almost perfectly shaped, is placed upon the last, requiring no adjustment from the hands of the operator in determining the center of the toe and heel, which are the portions first lapped upon the insole and secured into position by tacks. The lastis then adjusted in the machine, and the upper dragged upon the same by lifting-pressure brought to bear upon the sides of the last until the upperis closely fitted to the last and the edge brought above the level of the insole to be folded. Closingplates then complete the lasting by turning the vertical edge of the upper upon the insole,

and in so doing lay over the edge upon the insole regularly and uniformly.

The serrations upon the edge of the upper at the toe and heel and at the shank, or upon either portion, or any other portion of the upper desirable, enable the upper to be folded by removing such portions of the edge of the upper as are unnecessary for the purpose of securing the edge to the insole, and which, if permitted to remain, cause an extreme fullness, particularly at the toe, which cannot be easily plaited or folded upon itself by the closing of the lasting-plates.

Having thus fully described our invention, we claim and desire to secure by Letters Patent 1. A die for cutting'vamps or quarters, provided with a gage for indicating upon the vamp or quarter the degree of lap necessary in uniting the same in forming an upper.

2.'In combination with a die having portions of its cutting-edge serrated, for the purposes set forth, a yielding diaphragm provided with the projections 0 substantially as and for the purposes described.

3. The within-described vamp or upper 1 r vided with a lap-gage, impressed therein when the same is cut, substantially asset forth.
