The holder 0' has a stop similarto the stops it" employed in connection with the holders b; but the lever c is.normally pushed outward against the said stop by a strong llat spring, as the lower end of the said spring being secured to the holder by one or more To screws, as shown in the said figure.

The table A has secured to it at its upper 1 side a track, D, the upper side of which is beveled to form an inclined plane, the sides oi? the track being provided at each side with a groove, (1, parallel with the top of the track. This track is embraced by a carriage, l)',pro-

vided at its under side at each side the track with a tlange, d, which enters the grooves (Z, the said flanges and grooves preventing the carriage from being lit'ted ott the track in its 0 other suitable pad to prevent marrin g the upper ot the shoe. The threaded part of the screw (1* is extended through a nut, 1", having a milled or other enlarged head, 2. To support this nut so that it will sustain great 5 strain, the hollow portion of the carriage has low upright.

been provided with a shoulder, as at 3, upon which the lower end of the nut d rests at the same time that the under side of the milled head 2 bears against the outer end of the hol- This screw and nut may be readily lifted from the carriage whenever the shoe is out ot. the machine and the nut be quickly turned to enable the toe-rest to be set to approximately the proper height; but alfter the toe-rest has been applied to the hollow post and the shoe to be lasted has been applied to the toe-rest. then the nut may be readily turned. by grasping its milled head 2 until the toe-rest has been placed at exactly 50 the proper height or level.

The carriage D has bearings for the short shaft 0, upon which is secured within the carriage and below the screw d a pinion, e, which engages the rack D the outer end of the said shaft 0 having fixed to it a hand-wheel, c rotation of which enables the pinion in engagement with the rack to move the carriage longitudinally toward and from the heel-rest to be described, and in its movement the said the inclined plane at the top of the track I),

the incline being such as to enable the tocrest to be maintained in correct working position with relation to the curvature of the top of the last, notwithstainling the length of the last. 6 which may be screwed in against a gib, as

The carriage D also has a set-screw, as i i c, preferably olf brass, to prevent any longitudinal movement of the carriage, exce t when being moved through the operator en- 1 gaging the haiul-wheel c. i The heel-pin is composed of two parts, the l upper part, being pivoted. to the lower part, I f, by a screw or other stud, ,the lower part, f, being lixed to or rising from a cam-bh'a'ek, l f, fixed to the bed A. (See Figs. l and The part]" of the heel-pin receives loosely upon it above theblock fthecam-ringg, and upon the top of the said cam-ring is placed loosely a steel annulus, 1 which, when elevated upon the part f by the rotation of the cam-ring g, it resting on the cam block f, meets the beveled toe i at the lowereinl ol' the upper portion, of the heel-pin and tips the said portion f upon the pivot f the upper portion ot the heel-pin being at such time positively moved ftiu'ward toward the toe-rest [or a short; distance, or far enough to tirmly impinge the upper upon the toe-rest through the action of the last, the latter being thus tirmly locked in position before the operator commences to draw the upper over upon the bottom ot the last or the inner solelaid thereon, thus preventing any tendency of the last to twist or turn out of correct position.

The upper side of the cam-block f and the lower side of the cant-ring q, n-ovidml with a handle, g (shown in 1,) have each one or more cam-surfaces, as 8 fl, and a horizontal or plane surface, as it) 1; so that while the nut is moved for a portion oi a rotation the two cam-surfaces, being in contact, will hit the ring and annulus quickly; but as soon as the plane surfaces 10 and 12 come in contact, and while so in contact, the cant-ring cannot recede ort urn backward by reason otanyweight or downward pressure applied to it. orby reason of. a stroke or blow on the last, as would be-the case it both cam-surl'ames extended entirely around the cam block and ring.

The upper 71 of the shoe to be lasted has applied to it about its lower edge a draw-cord, thong, or wire, as I, the said draw-etiwd being extended through channels or pockets composed, as herein shown, of loops oi thread, the said loops and draw-cord, when put together in the shoe, resembling and constituting practically what is known as a lockstitch, the said loops and draw-cord being put in, it desired, by a sewing-machine having an eye-pointed needle and a shuttle. lt will be understood that this draw-cord may be connected with the upper of the shoe in any usual way, either as herein shown or as shown in United States Patent No. 248,566, dated ()ctober 25, 183i, to J. ll. Applegate. The up per having been prepared in this way and V placed upon the last 11, the usual inner sole, l 71., is applied, as shown in Fig. l, and the i last will be jaeked'lirmly in place by turning the handle 9 and nut (1. The levers I) c at l their upper ends (see Figs. 2 and 5) have applied to them loops or slides m, which are iheld in ad usted position therein by suitable setscrews, o. The loops or slides m are notched or cut away at their inner sides, (see Fig. 4,) so as to receive between them and the said levers and engage and hold the out er ends of the flexible connections n n n), (shown as a chain,) the opposite ends of the said connections having attached to them like weighted heads or swivels, 11 to which in turn are connected the hooks or draw-bars n" n n, the hooks or draw-bars being adapted to engage the cord, thong, or wire tto last the toe, the hooks or d raw-bars a engaging the draw-cord, thong, or wirenear the ball of the last, while the hooks or draw-bars or engage the drawcord nearer the heel, all as shown in Fig. 1. The shoe having been jacked, the hooks or draw-bars are seized by hand and hooked on the draw-cord, the operator at suchtime mo"- ing the levers Z) and 0 against the springs b and 0 the said springs normally acting to illsure the engagement of the hooks and drawcord when the operator removes his hand from the hooks. In this condition the operator depresses the treadle C and lasts the toe, or nearly so, and then by putting the foot on the treadles a the levers b are moved to last the upper along the full shank and heel.

Each lever or foot-treadle has co-operating with it a locking device, r, shown as a ratchettoothed spring-held bar pivoted at 20, the said teeth engaging the edge of a plate, n3, attached to the lever or treadle and holding the lever or treadle in the position left by the operator after removing his foot. This hooked bar at its lower end has a lug, 21, which is acted upon by a spring, 22, and the upper end of the bar at its rear side is acted upon by a pin, 24, normally pressed outwardly against the bar by a spring, 25. Each lever or treadle has mounted upon it a releasing device, as r, the said releasing device being herein shown as pivoted at 26, and of such shape that the operator with his foot upon the treadle may turn the releasing device to push the locking device backward against the spring, and thus release the lever or treadle in order that it may be moved.

In practice the upper and lower ends of the connecting-rods C and a are made ball shape, as shown in the sectional detail, Fig. 6, the said ends entering sockets in the arms and in the levers and treadles, the said ends being retained in the said sockets by clips, as 29, attached to the rods by screws 30.

\Ve do not herein claim nippers to engage the material of the upper, the said nippers being attached by flexible connections to levers by which the upper is drawn over upon the inner sole; but in our invention the hooks or draw-bars in all instances will be so constructed as to engage the shirr cord thong, or wire. The strain put upon the upper to fit it upon the last and to draw its edge over upon the inn er sol e is exerted throughthe said cord t. In practice the toe part of the upper will first be lasted, and then the ball and shank, and both sides may be drawn to the last simultancously, or either side may be drawn separately by means of the foot-treadles.

We do not herein broadly claim a series of arms, as 11 and e, nor do we broadly claim a toe-rest made movable on an inclined track, nor do we broadly claim a verti(ally-adjustable heel-pin.

Ye do not claim anything shown in the application of the said Hathaway and Paull. In our application the carriage containing the toe-rest may be slid on the inclined track, and all the arms or levers to which are joined the connections under the control of treadles are readily accessible to the foot of the operator leaving his hands free to manipulate the hooks or draw-rods and the upper.
