To all whom it may concern-.-

Be it known that I, JOHN J. HEYS, of Lynn, in the county of Essex and State of Massachw setts, have invented certain new and useful Improvements in Machines for Beating Out or Leveling the Soles of Boots or Shoes, of which the following is a specification.

This invention has relation to machines for beating out or leveling the soles of boots and shoes in which the boot or shoe is placed upon one of two alternately and oppositely acting jacks and is forced up against a mold or die; and it consists of a machine equipped with those important features of construction and arrangement which I shall hereinafter describe in detail and then point out in the claims hereto appendec Reference is to be had to the accompanying drawings, and to the letters and numerals marked thereon, forming a part of this specification, the same letters and numerals designating the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure l is a front elevation of my improved machine. Fig. 2 is aside elevation of the same. Fig. 3 is a vertical section through the machine. Fig. 4 is a transverse section on the line 4 4 of Fig. 1.

The machine is provided with side standards a a, preferably of castings, and united by a cross-head or brace c at their upper portion and a cross-head Z) at their lower portion, together with vertical rods or bars d d, threaded at their upper ends to receive nuts e. The side standards are also united by tie-rods ff, of which there may be as many as is necessary.

In the cross-head c are yieldingly mounted two molds or dies 9 h. The said molds or dies are provided with tongues fitting in dovetailed grooves in the die-carriers i, which latter are secured to the ends of rods j, passed through the cross-heads c and passing loosely through the hand-wheel 0, which has the externallythreaded sleeve 7t" screwed in the top of the cross-head, the said rod j being threaded at its ends to receive a nut l.

m is a strong spring having one end pressing against the die-carrier t' and the other end against the disk a, resting against the externally-threaded sleeve 7c of the hand-wheel 0, the spring, the rod j, and the disk all fitting in a tubular socket in the cross-head. By means of the said nut Z the tension of the spring upon the die-carrier may be varied, (the rod j passing loosely through the said sleeve, so that when pressure is put upon the said die-carrier and the die they may yield slightly upward,) and the die-carrier may be also adjusted by the hand-Wheel 0, which lies above the cross-head.

The die-carriers have outwardl y-proj eetin g bracket-s p p, which partly encircle the vertical rods cl, whereby they are guided in their vertical movement, which vertical movement, however, is very slight.

r is a rod similar to those at d cl and extending up through the center of the frame and likewise being partially encircled by the brackets 19 p on the die-carriers. This lastmentioned rod extends from the crossdiead c to the cross-head b and is provided at each end with nuts .9 t, threaded thereon.

u o are the jacks which cooperate With the dies or molds for beating out or leveling the soles of the boots and shoes. Each jack is mounted on a table 20, and they are moved alternately into pressure against their respective dies, means being provided for arresting the motion of the machine temporarily while each jack is pressing a sole against the die, thereby allowing the finished sole to be removed from its jack while the latter is at clearance.

For moving the jacks and their tables toward and from the dies or molds and forward out of the vertical lines of said dies to a position of clearance for the easier placing of the sole upon the jack I provide the following devices: a; m are inclined bars, each pivoted at one end to a bracket 3 on the side standards and extending forwardly therefrom, being adjustably held in a bracket .2 on the lower portion of the frame. The said bracket .2 has bolt Z1 passes, whereby the bar a: may be adjusted to any inclination relatively to the vertical lines of the molds or dies. On each one of the said bars 00 is a slide 0, having a groove to receive the said bar and also hava slot a, through which the mg a vertical groove to receive the vertical tongue d on the depending flange 6 of the table w.

The table is partially guided in its vertical movements by its tongue-and-groove connection with the slide and by the pin a moving in a vertical groove in the bracket 12 and is guided horizontally or transversely by the engagement of the slide with the inclined bar 00.

The means for moving the table transversely and vertically comprises a lever 71 pivoted to the table, and a guide-lever f, pivoted on a shaft g, extending between the standards. The pivoted ends of the two levers are bifurcated, as shown in Fig. 1, and the pintle connecting them is provided with rollers 1;. V

The lever h has an arm j with a roller projecting into a cam-groove Z in a bracket 4%, the said cam-groove having an inclined portion 1 and a vertical portion 2.

Mounted loosely upon the vertical central rod 1" is a large bevel-wheel it, having a camtrack 0, on which the rollers of the two levers h it rest, said rollers being held from sidewise movement by the levers f. The cam-track is so formed that when the disk is rotated the rollers are elevated and depressed alternately and oppositely, so as to throw the 'jacks alternately into their positions of pressure and clearance. During one half of a revolution of the bevel-wheel or disk with the cam-track 0 one of the jacks will be elevated and the other will be correspondingly depressed.

Referring to Fig. 3 and assuming that the rollers iof one set of the toggledevers are in their lowest position as the cam-track and the disk rotate or revolve, the lever h will be raised, which, by reason of having the arm j, with the roller extending into the camslot Z, will be forced rearwardly by the rods or, lying in the grooves in the slides c. The table and the jack are moved rearwardly until the jack is in the vertical line of the die, at which time the roller 7t will have reached the end of the cam-track in the bracket 717/. Then the pin a will enter the vertical groove of the bracket 19 as the roller It leaves the slot Z, and the jack will be guided vertically against its die.

As the bevelwheel n completes the last half of its revolution the weight of the jack and its parts will cause them to slide down to their first position 8, as shown in Fig. 3. The sliding connection of the table with the slide and the slide with the guide-bar :20 causes the said table to be always maintained in a horizontal position, as will be understood.

Motion is imparted to the bevel-wheel 'n, by a small bevel-wheel p on a shaft g, which is mounted in a bracket supported at one end upon the cross-head b and at the other end upon a standard 2". s is an oil-cup upon the said bracket, having ducts t extending down to the shaft q for keeping it constantly lubricated.

In addition to imparting to the jacks the movements before described I provide means for arresting the action of the machine, as aforesaid, when each jack is in its lowest position, such arresting being accomplished by the following devices: a is a continuouslydriven wheel mounted loosely upon the shaft (1 and having an inwardly-projecting ringlike flange Q2. w is a disk secured rigidly upon the shaft q to turn therewith and provided with an aperture 00' and a diametrically opposite aperture y, it being also provided with a ring-like flange z, corresponding to that at v on the wheel a.

a is a split friction-ring inside the flange n of the wheel and having the faces of its adjacent ends converging to receive between them the wedge-shaped end b of a lever d pivoted in ears on the disk to. The ring a has a lug c extending into the aperture 03 of the disk w, so that the ring turns with the disk-handle inside the flan ge 'u of the wheel a.

The downwardly-curved end of the lever d extends into a groove in a sliding sleeve f on the shaft q. When the sleeve f is moved away from the disk to, the end 11 of the lever d is wedged between the ends of the split ring a so as to expand the said ring against the ring 0) and by frictional engagement therewith to cause the rotation of the shaft q, and when the sleeve is moved toward the disk the wedge-shaped end I) is lifted to allow the ends of the split ring to approach each other to free the ring from frictional engagement with the flange i) and unclutch the wheel from the disk and shaft.

For sliding the sleeve f I employ a bellcrank lever g having an arm 7L2, connected by a spring 1' with the frame and pivoted upon one of the tie-rods f. The bell-crank lever has a hub or sleeve j extending on both sides of the same, with forwardly-projecting lugs 70 (See Fig. 4.)

VP are foot-levers, each having a hub or sleeve m upon the tie-rod f, with a lug n resting loosely upon one of the lugs k of the hub Thus it will be seen that by depressing either of the levers Z its lug n will engage one of the lugs 70 so as to throw the arm 6 2 of the bell-crank lever forward and through the medium of the SlGGX'G f and the lever d clutch the shaft and the wheel together. The bell crank lever, however, may be thrust downwardly independently of either of the two foot-levers. Each lever f has a rearwardly-extending arm 0 with a sleeve 19 loosely pivoted inthe bifurcated ends thereof by a pin (1 r is a link connecting each end of the foot levers, with the lever f passing loosely through the sleeve 19 thereon. When the table and the jack have reached their lowest positions, the end 0 of the lever f will be at its highestposition and and having a nut s the soles of boots will have raised the lever Z which was depressed to start the machine, through the medium of the rod r so as to unclutch the wheel a and the shaft p thereof, stopping the movement of the machine, the arm 9 of the bell-crank lever being provided with a brake-shoe v adapted to impinge upon the disk 20 when the said arm 9 is in its rearward position. lVhen it is desired to start the machine again after having placed afresh sole upon the jack, which is in its lowest position, the other foot-lever Z is depressed to clutch the wheel and the shaft together.

By observing Fig. 2 it will be seen that when one of the levers is raised to unclutch the wheel of the shaft the other lever Z may be easily depressed, since its corresponding leverf is raised and the link 1- extends some distance through the sleeve 11 on the end 0 of the said lever f.

The unclutching action of the parts is caused entirely by the spring 2' which also operates the brake, the foot-lever being employed only for clutching them. In starting the machine the foot is kept on one of the levers until one of the levers f raises the other footlevers and allows the spring to unclutch the shaft from the wheel.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it maybe made or all of the modes of its use, I declare that what I claim is- 1.
