dated ful Machine for Lasting Shoes; and Ido hereby declare the same t'o'be fully described in the following. specification and represented in the accompanying drawings, of which- Figure l is a top view; Fig. 2, a front ele- Fig. 3 is a "ertica-l and longitudinal section. Fig. 4. is a vertical and transverse section of it. Figs. 5 and 6 are side views of the levers which carry the side and shank lasting jaws; Figs. 7 and 8, topjviews thereof. Fig.9is a transverse section taken through one pair of side-lasting jaws and their holding levers; Figs.'10, 11, and'12, top andside' views of the jaw-adjusting mechanism, whereby the carriages are moved longitudinally along theframe to adapt the jaws to lasts of different lengths; and Fig. 13, a perspectiveview of one of the carriages detached from the machine.

In this machine the upper, at the toe and heel of the shoe, is first turned over upon the inner sole, and then. the upper, at the shank and along the sideof the shoe, front and back of the shank, is turned over upon the inner sole by in'dependently-operated shank and side lasting devices, two or more sets, denominated by me as lateral jaws, they being adapted to be moved laterally over the inner sole and last toward the center liueo'f the last, and being made horizontally movable with relation to the bottom of the last .by independent carriages, upon which the said shank and side lasting devices or lateral jaws. are mounted, and being also vertically movable, as herein after described.

The carriages which carry the side-lasting devices or jaws that operate upon the upper at the sides of the toe and heel also carry the toe and heel lasting jaws. These lateral jaws, which operate upon the sides, ball, shank, and toe and heel of the upper, are simultaneously adjustable longitudinally, or in the direction of the last, by carriage and jaw moving devices adapted-to separate the jaw-carrying carriages from or cause them to approach each other and be held in 'pro 'ier-place, according to-the length of the last.

In this embodiment of my invention the ad justing devices for moving the jaw-carrying carriages are adapted-t0 move the carriages of the shank lasting devices and that pair of ball-lasting devices next in front of it toward the toe of-the last for a less distance than the heel and toe lasting jaws and their attached side-lasting jaws or devices.

The termlastingdevicwis herein intended to include and refer only to'that class of device which is adapted to act against and lay the edge of the upper horizontally over and hold it in position upon the face of the inner'sole, to be there secured by nails-or A denotes a prismatic box or frame, mounted on a stand, B, in such manner as to becapable of being turned horizontally around on a'tubular pivot, to, projecting upward therefrom, a

heel and toe rests E F, which are screwed thereon, in order that they may be adjusted to different heights to adapt them to receive and support the last at the proper altitude.

The heel-rest E is cylindrical, and is providedwith a shoulder, d, to serve as a stop for the heel of the last, and the toe-support is inclined, as at cf, to fit the fore partof the last. The toe and heel rests are properly disposed between a pair of heel and toe lasting jaws, G H, which are adjustably connected by set,- screws 9 g with the slotted upper'eiidsof the jaw-carrying levers II, so as te -"permit the said jaws to be adjusted to the proper altitude with relation to the last. These heel and toe jaw-carrying levers are pivoted upon heel and I toe carriages N N and are, at their lower end's,.co nnected by toggles K K, jointed to v the upper part,'t, of a vertically-reciprocating pitlnan, L, whose lower end, extended through the tubular pivot a, is connected with the pedal M,pivoted to the stand at B, so that by drawing down th e-said pitman the said heel and toe jaws will'he simultaneouslyclosed upon the shoe, after which, as hereinafter described, further descent of the said pitman will operate theshank and side lasting devices to close the upper over upon the faceof the inner solo.

The rod is should be so applied to the pedal as to be capable of being revolved horizontally,

.in order to effect the connection of such rod with the foot i of the pitman, into which it is screwed, the same serving to enable the pit.- man to be lengthened or shortened, as occasion may require.

The lower portion of the rod k is provided with an elevating-spring, 'n, and slides freely through a horizontal cross head or bar, I, from which four or any other suitable number of pairs of s 'irings, m an, are extended upward and arranged in manner as represented, the said springs acting as connecting-links between the said crossrh'ead and the shank and side lasting devices or lateral jaws, to be hereinat'ter described. These springs m, at their upper ends, are connected with the levers m, m, arranged in pairs, one pair within and supported upon each of the carriages N N N" N, mounted so as to he slid horizontally upon the top of the box or frame-work A.

The levers m, in pairs, rest side by side, and are provided with seats m to rest upon the upper edges of the ends of the said carriages N N N? N, represented in Fig. 2.

Each lever m m of the series carries a lateral jaw, to operate either on the shank or side ofthe shoe, the jaw being formed as represented, and applied to the lever in a manner as showirin Fig. 9, wherein the foot of the arm of the jaw, provided with a tenon, o, is projected into a mortise, 12', made in the lever m, a screw, q, projected downward from the lower part of the arm of the jaw, receiving a shouldered nut, a, which rests upon the lever m, and is kept in place thereon by a cap, 8, fastened to the lever by screws tt, the whole being as shown in the drawin By revolving the nut r the jaw may be elevated ordepresscd so as to properly adjust its upper portion, .70 to the level of the sole of the last, when such last may be in position on the heel and toe rests E F.

The lateral jaws for operating upon the upper along the sides of the shoe and last between the heel and toe lasting jaws, already described, may. be designated, according to their functions, as the shank, ball, and side lasting jaws, all of the said jaws acting, however, upon the side of the shoe.

The shank-lasting jaws are marked 0, the ball-lasting jaws O and the side-lasting jaws O and 0, these last-mentioned jaws, however, being shown as connected with the same carriages which carr 'j the heel andtoe lasting jaws. Each of these jaws has an acting edge, (designated by the letter m,) which is adapted to act upon and force over upon the face of the inner sole beyond its edge the upper of the shoe being lasted.

These pairs ot'jaws O O 0 O and their levers m are each pivoted upon the independent carriages N N N 2 N respectively, and each of these carriages is provided with a stud, c, which is extended therefrom into one or the other of the oblique slots to or 'w of a carriage and jaw moving device shown as a yoke, 1, connected with the brackets 3 ot' the frame by adjusting-screws m .r, the whole being so as to enable the yoke to be elevated or depressed by the said screws .r a.

'hilc the yoke is being raised its oblique slots,-operating on the studs of the carriages N N N N will cause such carriages to simultaneously move apart from one another the pairs of jaws carried by them, the said jaws being thereby moved longitudinally with re lation to the length of the last, toadapt the machine to last shoes of different sizes.

A downward movement of the yoke will cause reverse motion of the several pairs of lateral jaws-tbat is, they will be moved to ward each other for smaller shoes.

It will be seen that the adjustment of the lateral jaws, both vertically and at different distances apart, enables them to be adapted to any last, so as to properly operate therewith in lasting a shoe. By depressing the pedal the heel and toe jaws'will first be moved up to the last, after which the others or lateral jaws will be advanced toward it, the jaws of each pair opening or moving apart during therise of the pedal, the said opening being due to the reaction of the spring it.

From the above it will be seen, after an upper or vamp of a shoe is applied to the last, and an insole placed thereon, and the last is fixed in position on the rests E F, that I have only to depress the pedal to cause the heel and toe and lateral jaws to grasp the said upper and crowd it over firmly upon the innersole on the last, to which inner sole the upper may then be secured by tacks or other proper means. i i

The slots 10 or, which operate the carriages N N, are more oblique than the slots w to, which act upon and move the carriages N N, thathold the shank and ball lasting jaws O 0, and a certain equal movement; of the carriage-moving device 1 at both ends will move the carriages N N over a greater distance than the carriages N N", as is necessary and essential inthe proper-proportioned adjustment to adapt the heel and, toe and lateral jaws to shoes of difierent lengths.

Prior to this my invention, so far as I am aware, the upper hasbeen laid over upon the inner solo by single plates extended along the side of the last, and these plates have been changed for shoes of difi'erent sizes and I am not aware of any lasting mechanism wherein independent sets of narrow jaws or devices at the sides of the last have been made adjustable in the direction of the length of the last, to enable the same lateral jaws or devices to lastshoes of different sizes.
