QPEQIIPICATION forming part of Letters Patent No. 296,486, dated. April 8, 1884.

Application filed September 2], 1883. (No model.)

To all whom it may concern:

Be it known that I, SETH D. TRIPP, of Lynn, in the county of Essex and State of Massachu setts, have invented certain new and useful Improvements in Machines for Leveling Boot and Shoe Soles, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings,tforming part of this specification, in which the similar letters of reference indicate corresponding parts in allthe figures.

Figure 1 Sheet 1, is a front elevation of my improved machine, partly in section. Fig. 2, Sheet 2, is a sectional plan view of the same, taken through the broken linea; :v a: a a, Fig. 1. Fig. 3, Sheet 2, is a sectional side elevation of the same. Fig. 4, Sheet 2, is a side elevation of a part of the same, showing the loose pulley, the fixed pulley, and the brake.

The object 'of this invention is to facilitate the operation of leveling the soles of boots and shoes and promote convenience in controlling the machine for performing said oporation.

The invention consists in a machine for leveling boot and shoe soles, constructed with a shaft connected with the drive-shaft by beveled-gear. wheels, and provided with a right and a left worm gearing into wornrsgments carrying the last and pressenfoot, whereby the said last and prcssenfoot are made to move in unison. The prcsser foot rod is placed. in a socket in the spoke of the wormsegment, and is held out by a spring, so that the said pressenfoot will adjust itself to the varying thickness of the soles. The machine is provided with two worm-shafts, two pairs of right and left worms, and two pairs of wor1nsegments, arranged to carry their pairs of lasts and presserfeet at the same time and in opposite directions, to adapt the two pairs of lasts and presser-feet to beattended by the same operator. The last-carrying worm-segments are provided with spring-pressed rods for holding the heels of the boots and shoes from.

rising on the lasts when pressure is applied to their toes. The shaftthat carries the brakesockets, blocks, and shoes is provided with elastic arms, operated,succcssively,by a screwnnt moving upon the drive-shaft to apply the brake, the said brake being withdrawn by upon the shaft 13.

said shaft.

springs put under tension by the movement of the said shaft in applying the brake, as will be hereinafter fully described.

A is the frame of the machine, in hearings in the lower rear part of which revolves a shaft, 13.

To the ends of the shaft B are keyed or otherwise attached pulleys O, the outer parts of the faces of which are beveled to receive the shoes of the brake, hereinafter described. The inner parts of the faces of the pulleys C are beveled to fit against the beveled inner surface of the rims of the pulleys D, placed loose The two loose pulleys are revolved continuously in opposite directions by belts driven from a steam-engine or other convenient power. The inner ends of the hubs of the loose pulleys D have annular grooves formed in them to receive the forked arms E of the shaft F, which slides longitudinally in bearings attached to the frame A, so that the direction of mot-ion of the shaft B can be changed by the longitudinal movement of the shaft F throwing one of the pulleys D outof gear and the other into gear with a fixed pulley, O. The shaft F can be moved to reverse the motion of the shaft 13 by a lever, G, the inner end of which is connected with the said shaft F or with a pin, I-I, attached to he The lever G is fulcrumcd to the forward part of the frame A of the machine, and its outer end projects into such a position that it can be readily reached and operated by the attendant.

Upon the middle part of the shaft B is.

formed a screw-thread, l, upon which is placed a nut, J. Upon the side of the nut J is formed, or to it is attached, an arm, K, which projects inward and has a hole formed through it to receive and slide upon the shaft F, so that the collars L, it moves the shaft F longitiulinally and moves the loose pulleys D to release the pulley O that has been driving the screw-shaft B and throw the other pulley G into gear, so that the said shaft B will be driven in the op posite direction. As the nut J is about completing its movement in either direction, it strikes one of the arms M, attached to the shaft N, and moves the said shaft longitudinally. The shaft N slides in bearings attached to the frame A, and to its endsare secured, by setscrews or other suitable means, socket-arms O, in which are placed blocks P, having brakeshoes Q hinged to their outer ends. The brake-shoes Q rest against the beveled outer part of the faces of the fixed pulleys C, so that the brake will be applied and withdrawn by the lateral movement of the brake-shoes Q as the brake-shaft N is moved longitudinally.

Upon the rear sides of the brake-shoes Q are formed ribs R to receive the hinging-pins, and which enter slots in the outer ends of the socket-arms O, to prevent the said brake-shoes Q from having a lateral movement upon their supports. The brake-shoes Q are held forward by set-screws S, which pass through screw-holes in the closed ends of the socket arms 0 and enter recesses in the inner ends of the brake-blocks P, so that the said set-screws will also serve as stops to prevent the inner ends of the blocks 1? from rising, and as pivots to allow the outer ends of the said blocks to move up and down freely. The brake-shoes Q are held in proper positions by springs T, attached to the socket-arms O, and which rest against the projecting ends of the brake-shoe pivots or other supports attached to the brakeblocks 1?. The brakeis held against the downward pressure of the friction of the fixed pulley upon one side of the machine, and against the upward pressure of the other fixed pulley by studs U, formed upon or attached to the socket-arms O, and which rest against and slide along stop-bars V, attached to supports XV, secured to the frame A.

It will be observed that when the brake is acting the axis of the shaft B, the pivot of the brake-shoe It, and the pivot of the brake-block P are in a straight line, or nearlyso, so that the instant the motion of the brake-pulley O is reversed the brake-shoe will be carried in such a direction that its pivot will be carried out of the said line, and the brake will thus be withdrawn from the said pulley.

The trip-arms M are made elastic, so that they may yield, and thus be prevented from being broken should the brake-shoe come to its seat too long before the shaft B has completed its movement.

The brake-carrying shaft N, when the arm L is released, is brought back to a central position, ready to be moved in either direction, by two springs, 70, attached at one end to the inner sides of the lower side bars of the frame A. The other ends of the springs 10 rest against the inner sides of pins or collars Z or other is moved in either direction by one of the arms M, one of the springs It will be put under tension, and the stop Z will be withdrawn from the other spring, so that the action of the first spring in returning the said shaft to its central position will be unobstructed.

- To the shaft B, at a suitable distance apart, and with their toothed sides toward each other, are secured, by set-screws or other suitable means, two beveled-gear wheels, X, the teeth of which mesh into the teeth of the beveledgear wheels Y, attached to the lower ends of the two shafts Z, so that the said shafts will be revolved at the same time and in opposite directions. The shafts Z revolve in bearings attached to the frame A, or to supports secured to the said frame.

To the lower parts of the shafts Z are attached right worms a, and to their upper parts are attached left worms 1). The threads of the worms a 71 mesh, respectively, into the teeth of the worm-segments c d, the hubs of which rock upon mandrels e f, secured in suitable supports formed in or attached to the frame A. By this construction, as the two shafts Z are revolved in opposite directions, each pair-of right and left worms a b will move its wormsegments a (Z in opposite directionsor toward and from each other, as the direction of mo tion of the said shafts is changed. The two pairs of worm-segments c d are so arranged that the segments of one pair will be approaching each other while the segments of the other pair are moving from each other.

In the spokes of each lower segment, 0, and near its hub, is formed a socket, g, to receive the lower end of the rod h, to the upper end of which is attached, or upon it is formed, a last, The lower end of the rod h is secured in place in the socket g by a set-screw, j, or other suitable means, so that the last can be readily adjusted or (letached and replaced by a last of a different size; or the last can be changed by removing the pin or other fasten ing that secures it to the rod h.

Upon the spoke of each segment d is formed a socket, m, to receive the upper end of the rod it, upon the lower end of which is formed, orto it is attached, the presser-foot or former o. The rod or shank a is secured in the socket m by a screw, 9, which passes through a slot in the side of the said socket on and screws into the said rod n, so as to hold the said rod from turning and from dropping out, while allowing it to have a free longitudinal movement for the length of the said slot. The rod 01 is pressed outward by a spiral spring, q, placed in the upper part of the socket m. Upon the upper end of the spring q is placed a disk, 1', against which rests the end of a screw, 8. The screw 8 passes in through the closed up per end of the socket m, so that the tension of the spring q, and consequently the pressure applied to the boot or shoe sole, can be regulated, as maybe required. The presser-foot 0 is so formed as to press the sole into the hollow of the last and round off the face of the sole, so as to give the said sole the desired form while leveling down inequalities and smoothing the said sole. The segments a d of each pair are so arranged that as the said segments move from each other the heel of the presser-foot 0 will come in contact with the heel of the boot or shoe sole, and will act upon the said sole from heel to toe, and in the return movement from toe to heel. The two pairs of segments are so arranged that the segments of one pair will be moving toward each other as those of the otherpair are moving from each other, so that as each last is at the inner end of its movement the other last will be at the forward end of its movement, and the boots or shoes can be removed from the said lasts and replaced with others. alternately, and both lasts can be attended by the same person.

23 is a rod, the lower part of which rocks in bearings u,attached to the spoke of each lower segment, 0. The upper part of the rod t is bent forward and upward to bring its upper end into such a position as to rest against the quarter of the boot or shoe, and prevent the heel of the said boot or shoe from rising on the last when pressure is being applied to the toe of the sole.

Upon the upper part of the rod i is placed a coiled spring, v, the upper end of which is secured to the said rod, and its lower end is secured to the upper bearing, a, or to the spoke of the segment 0, so as to hold the end of the said rod against the boot or shoe with the requisite pressure.

To the lower end of the rod t is rigidly attached the end of a laterally-projecting arm, w, to the outer end of which is attached the rear end of a bar or cord, re, the forward end of which is connected with a pin or other catch attached to the forward part of the franie A, so that by means of the said bar or cord the rod it will be swung back from the last i and held while removing a boot or shoe from the said last 2'- and putting on another.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
