JOHN VEASY'COLLIER, OF NORTHAMPTON, ENGLAND.

MACHINE FOR MAKING HEEL S FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 593,349, dated November 9, 1897. Application filed February 10,1897- Serial No. 622,830. (No model.)

To all whom it may concern:

Be it known that 1, JOHN VEASY COLLIER,

a subject of Her Majesty the Queen of Great Britain and Ireland, residing at Northampton, in the county of Northampton, England, have invented certain new and useful Improvements in Machinery for Making Heels for Boots or Shoes, of which the following is a specification.

This invention consists of the herein-described new or improved machinery for making heels for boots and shoes whereby there is a considerable saving of labor, thus reducing the cost of manufacture. Moreover, all the heels of a certain size can be built to a uniform height, and the split lift can be built in the heel withthe other sections instead of being nailed onto the bottom after the heel is built. 7 Y

7 I will describe my invention by referring to the accompanying drawings, in which Figure l is a front sectional elevation of a.

boot and shoe heel making machine constructed according to this invention. Fig. 2 is a sectional side elevation of the same on line X X of Fig. 1. Fig. 3 is a sectional side elevation of the same on line Y Y of Fig. 1. Fig. 4 is a front elevation and plan of one of the pressure-blocks of the said machine. Fig. 5 is a front elevation and plan of one of the distance-blocks of the said machine. Fig. 6 shows a part of one of the said pressureblocks in front and side elevations and in plan. Fig. 7 is a plan of one of the heelmolds of the said machine, and Fig. 8 is a plan of one of the treadles of the said machine.

The same letters indicate the same parts throughout the drawings.

The said machine is constructed and operated as follows:

A is a machine-bed suitably supported, as by the legs a a Fixed to the bed A are four standards (marked B B B B provided with top bearings 19 b b b, in which revolves the three-throw crank-shaft 0, provided with fly-wheel c and driving-pulleys c 0 D D D are three plungers guided for vertical movement by the guides E E E fixed to the standards B B B B. These plungers are connected to the three-throw crankshaft 0 by the connecting-rods F F F which at their top ends f are respectively jointed to the throws of the crank-shaft C and at Mounted so as to be capable of sliding to and fro upon the bed A are three heel-molds G G G which are each shaped internally at g to correspond with the shape of the sides of the required heel, so as to receive the various sections of which the heel is builtup. Each of these molds is guided by two planed strips a a cast on the bed A and between which the mold will slide. p

Under the plungers D D D and above the molds G Gr G I provide the three pressureblocks H H H which are arranged for vertical movement by fitting on the two upright studs 1 I fixed to the bed A of the machine. Upon each of the studs 1 I is a coiled spring J, which springs are strong enough to raise and maintain thepressure-blocks in their highest positions against the nuts 2" on the top of the studs. Each of the pressure-blocks H H H has a removable projecting lower part h, adapted to fit into the corresponding mold and press onto the heel therein. The under side of the projecting part h is made of a shape to correspond with the seat of the boot upon which the heel when built is to be fixed. On the top of each of the pressure-blocks H H H there is a sliding distance-block which is marked, respectively, K K K and are adapted to slide in guides k formed on the top of the pressure-blocks. For each of the distance-blocks K K K I provide means for pushing the distance-block forward between the bottom of the corresponding plunger and the top of the pressure-block, so that the plunger will then act upon the distance-block and force it and the corresponding pressureblock down. The means for operating the distance blocks consist of three treadles, (marked, respectively, L L L one for each distance-block, turning on a fulcrum-shaft Z and continued beyond the same as an arm P, which by means of the connecting-rod Z is connected to the arm l of a bell-crank lever which turns on a fulcrum-pin Z and the other arm Z of which has a pusher-piece 1' connected to it, so that when the treadle is pushed m, connecting it to a bracket m on the machine-frame, so as to draw the distance-block back from underneath the plunger at the proper times, as hereinafter described.

- adhesive mixture.

Each of the three pressure-blocks H H H is provided with two downwardly-projecting ratchets or catches h3 71 which at 71 are jointed to the pressure-block and near their lower ends each is made with a notch h. These catches pass through holes in the bed A and at their lower ends are connected together by a coiled spring h so that when the pressureblock has been forced down to compress the boot-heel in the mold, as hereinafter described, the notches it will engage underneath the bed A and thus maintain the pressure-block in its lowest position. In order to release the catches 7L3 h to allow the springs J to raise the pressure-blocks, I provide for each pair of catches two small bell-crank levers 11. M, which by the rods n n are connected to the shorter. arm n of the corresponding treadle-lever N, N or N which turn on the fulcrum Z, so that when one of these treadlelevers N N N is depressed the shorter arm n of the lever, together with the two connecting-rods n n jointed thereto, rises and turns the bell-crank levers 11. n so as to force the catches h h farther apart, as shown on the right-hand side of the machine, Fig. 1, so that the notches h will then be free or the bed A and the pressure-block will rise.

The machine above in part described acts as follows: The various lifts or sections 0 of which the boot-heel is to be made are placed in one of the moldssay the first mold Geach lift being slightly covered with paste or other The mold G will then be g in the position in which the mold G is shown in Fig. 3. The mold G", with the heel-section 0 in it, is then slid back along the machinebed A until it comes in contact with the screwed adjustable stop 19 at the back of the machine, when the mold G will be immediately underthe pressure-block H, the exact position of the mold being regulated by the stop 19. The workman now depresses the treadle L, causing the pusher-piece Z to push the distance-block K under the plunger D, so that this plunger in descending acts upon the distance-block K and forces the pressureblock H down, so that its lower projecting part h acts upon the sections 0 in the mold G, and the pressure-block is held in this position by means of the catches 71, 71 engaging under the bed-plate A, as shown in Fig. 1. The operator now places the lifts of another heel in the second mold G and slides this mold under the plunger D and depresses the treadle L so as to insert the distanceblock K under the plunger D which will then depress the pressure-block H and compress the sections in the mold G as shown in Fig. 1. The operator then similarly forms another heel in the third mold G and de presses the treadle L so that the heel in the ence to the other two pressure-blocks. Immediately the plunger D has acted upon the distance-block K and depressed the pressure-block H, as above described, so that the 7o mold G is compressed by the pressure-block H similarly, as above described, with refercatches 71 k catch underneath the bed A and V the plunger has commenced to rise, the spring m draws back the distance-block K, so that the moving plunger does not continue to act upon the pressure-block after it has been se- 7 cured in its lowest position by the catches.

The first pressure-block H can now be released from the first mold G by the operator depressing the treadle L, which, as above described, throws outwardly the catches h h free of the bed A and allows the pressureblock H to rise. The operator then draws mold G forward to the position sh own by the mold G in Fig. 3 and the heel 0 is removed from the mold and the sections or lifts for another heel are placed therein and the mold G is slid back underneaththe pressure-block. H and the heel is compressed, as above described, and so on, each heel being properly compressed while two other heels are being built.

In order to facilitate the removal of thefinished heel from the mold, I may provide for each mold a lever, such as Q, which turns on a fulcrum g at the front of the machine,and

has a piston g jointed to one of its arms q immediately underneath the cavity 9 in the mold, so that when the lever Q is depressed the pusher will be raised and push the finished heel out of the mold.

Each of the treadles L L L is provided with a coiled wire spring Z connected to the bed A of the machine for lifting the treadle after it has been depressed, and the treadles N N N are similarly provided with springs n for lifting them.

It will be seen that as the pressure on the lifts of the heel is applied by power and is continuous the pressure is equal on each heel, and therefore those heels which are nominally of the same height can all be built to a uniformheight.

It will be evident that, if desired, the machine may be constructed with only one or two or with more than three of the molds G G G and corresponding pressure-blocks and plungers and accesssories without departing from the nature of my invention.

I wish it to be understood that I do not limit myself to the precise details herein described, and illustrated by my drawings, as it will be evident that they may be varied to some extent without departing from the na-- and shoes comprising a heel-mold adapted to slide to and fro on the bed of the machine, the pressure-block guided for Vertical movement above the said mold, catches for maintaining the pressure-block in its lowest position, springs or like means for raising the said pressure-block, a plunger and means for moving the plunger up and down above the pressure-block, and a distance-block with means for inserting the same between the plunger and the pressure-block to cause the plunger to depress the pressure-block and compress the heel in the mold, all substanv tially as hereinbefore described.
