,LASTING- SPECIFICATION forming part of Letters MACHINE.

Patent No. 236,218, dated January 4, 1881.

Application filed September 7, 1880. (No model.)

.- Monroe and State of New York, haveinvented a new and Improved Lasting-Machine, ot'which the following is a specification.

The object of this invention is to provide a cheap, simple, and durable machine whereby boots and shoes can be lasted in a better man- 4 stretched.

Figure 1 is a side elevation of the device, partly in section. Fig. 2 is a sectional end elevation on line a: m, Fig. 1. Fig. Sis a crosssection on line y 3 Fig. 2.

Similar letters of reference indicate corresponding parts.

In the accompanying drawings, A represents the frame, made of any suitable material, and designed to be fastened on a bench Or table.

B is the last block or seat, constructed with a heel end, a, and a toe end, I), the top of the former being of sufficient height for work to be done between it and the table, and being curved to fit the curve in the top of the heel Of the last, and provided with a pin, 0, extending above the said curve, soas to enter the corresponding hole 0 in the last 0, as shown. The toe end b is made of corresponding height, with a curved face, I), to receive the upperface of thetoeof thelast O, as shown. Said seat B may be constructed of metal or wood, in one piece, as shown, or it may be constructedin two parts, united or in contact just back of the toe, so that the heel part may be 'moved without disturbing the toe part, and

the length of the said seat B be thereby adjusted to lasts of difierent sizes.

Secured to the front-end timbers of the frame A, by bolt 61 or other device, is a lug, D, tightened in place by a wedge, D, that extends inward and has pivoted on it vertical pins ff,

so as to move in horizontal planes. The two levers E E consist of metallic bars inwardly curved to conform with the side outlines of the last 0, near the bottom thereof, and are also curved flatwise to conform in a measure with the curve of the bottom of the said last 0, and said levers E E are provided with flanges g g, which extend inward about a half an inch, or thereabout, from their upper faces, so as to fit'upon the outer face of the bottom of the boot Or shoe, (that is being lasted,) along the sides thereof. These flanges g 9 may be integral parts of the levers E E, or may be made separately and be secured thereon by bolts, screws, or other suitable devices. The levers E E are of sufficient length for their rear ends to rest on an adjustable-rest cross-bar, E, of the frame A, as shown, and are so hinged on the pins f f that they can be closed closely about the last 0 and the leather F upon said last 0, and can be opened apart to permit the easy removal of last 0 and the leather, F, that is stretched upon it.

.G is a flat metal plate, called a templet, of the general shape of the bottom of the. last 0, and provided with holes hh around its edge for the engagement of the hooks H H, that suspend the clamps I I. Said templet G is provided on its surface with lugs m m, by which it is suspended on pins n n from rods K K, which extend up through the top of the frame A and through a plate, G, fixed thereon, and have their upper ends pivoted to eccentriclevers L L, that are themselves pivoted or ful- 85 crurned on pins q, that pass through their curved slots sin the tops of the standards M M, which rise from the plate G, whereby said templet G and its connected clamps I I can be raised and lowered at will to any desired extent.

N N represent holding or pressing screwbolts, that pass down through suitable screwholes, 0 o,in the plate G, and freely through the templet G, so that their points will rest upon thelastO. These holding-boltsNNare designed to hold the last 0 firmly down in its seatduring the process of lasting a boot or shoe, and I they may be made to screw up or down, as indicated in the drawings, or may be adjusted 100 by levers or other suitable devices.

The clamps I I are suspended from the hooks H H with their clamping-points downward to seize the edges of the leather F, and they are provided with set-screws p p, for adjusting the gripe of theirjaws or points upon said leather F. Clamps of other construction may be used for this purpose; but those herein shown are effective.

0 is the gathering cord, designed to be drawn and tied around the stretched leather F, between the clamp I I and bottom of the last 0, after the said leather F has been sufficiently stretched, in order to draw it more closely in about the last 0, and to make it fit thereon more smoothly.

To last a boot or shoe on this machine, I take the upper-leather, F, for a boot or shoe that has been prepared for lasting, and turn it bottom up and insert the last 0 therein bottom up, said last 0 having an insole already tacked on the bottom. I then place the last O bottom up in the seat B, so that the pin 0 shall enter the corresponding hole 0 in said last 0, the toe of the last 0 resting in curve I) of the said seat B. Then I lower the templet G to the full extent, and adjust the clamps I I, making them grasp the upper-leather F all around the edge thereof, first grasping at the center at the heel, then at the center at the toe, and then, at proper distances apart, all around the said leather or upper F. Then I force down the holding-bolts N N upon the last 0, thus forcing said last 0 firmly down on the seat B; and next I draw up the templet G by means of the eccentric-levers L L, thereby pulling up the clamps I I, and consequently the upper-leather F, closely to the last 0, at every point alike; and said last 0 being firmly held down, all the surplus leather of the upper-leather F is then above the bottom of said last 0. I now close the flanged levers E E, thereby pressing the upper-leather F to the shape of the last G, all around the bottom thereof, at or about the insole, which has been tacked thereon. I next put on my gathering-cord 0 about the said upper-leather F and draw it tight; then release the eccentric-levers, pull again on the cord 0, and secure it, and the boot or shoe is then lasted all ready for tacking, which tacking may be done in the machine while the last 0 rests on the seat B on opening the levers E E; or the boot or shoe, or rather the upper-leather F, may be removed, with the last 0, to a place prepared for the convenience of the tacking.

Having thus described my invention, I claim as new and desire to secure by Letters Pateut 1. A lasting-machine constructed substantially as herein shown and described, consisting of a suitable frame, A, last-seat B, curved levers E E, templet G, provided with hooks and clamps H I, respectively, eccentric-levers L L, connecting-rods K, holding-bolts N N, and gathering-cord O, as set forth.

2. The combination, with the clamps I, of

screws 1), hooks H, and the adjustable templet G, to regulate the action of said clamps, as and for the purpose set forth.

3. In a lasting-machine, as a means for stretching and holding the leather F on the last 0, the combination, with the clamps I and holding-screws N, of the gathering-cord 0, substantially as herein shown and described.

4. In a lasting machine, as a means for stretching, forming, and holding the leather F on the last 0, the combination, with the clamps I and holding-screws N, of the curved levers E E, substantially as herein shown and described.
