HEEL-MACHINE.

SPECIFICATION forming part of Letters Patent No. 297,437, dated April 22, 1884.

Application filed July 17, 1883. Renewed March 19, 1884. (No model.)

To all whom it may concern:

Be it known that I, EDWARD H. PARKS, of Providence, in the count-y of Providence and State of Rhode Island, have invented anew and useful Improvement in Heel-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

-l\Iy invention is an improvement upon the heel-making machine for which Letters Pat ent of the United States were granted to E. S. Mansell, and numbered, respectively, 262,902 and 263,293.

The specific features of the invention include a rotary table carrying the cutting-dies underneath the reciprocating die-block; an intermittent movement of this rotary table, whereby it is causedto remain atrest while forming the heel, and to move so as to carry the filled die to the discharging point; placing the movement of this under the control of the op-.

erator,so that the table may be made to move at the instant the die is filled; the combination of a rotary shifting device for the inner and outer dies; the combination of a cutting-die held stationary during the formation of a heelblank therein, with a movable pasting device acting alternately with the cutting-block; a movable protecting arm -or guard; a press combined in the machine with a cutting mechanism; an automatic transferring mechanism, whereby heel-blank is transferred to the press; and details of'construction whereby these main features are practically embodied in the machine.

In the accompanying drawings, Figure 1 represents a front elevation of the machine. Fig. 2 shows an elevation of the right-hand side of the machine. Fig. 3 is a top view. Fig. 4 shows a section on line 00 w of Fig. 1. Fig. 5 is a section on line 11 y of Fig. 1. Fig. 6 shots a section on line 2 2 of Fig. 1. Fig. 7 shows a central transverse section of the cutting-dies and their adjusting mechanisms. Fig. 8 shows in side elevation the discharging device for the upper presser die. Fig. 9 shows discharging devices forthe lower.

In these figures, the sides A of the main frame are substantially like those in the patent referred to. In slots in their upper ends are the ends of the cross-head B, which carries the block 0. These ends project through the sides, and are connected by pitmen to wrist pins on the shaft E, which has its bearings in the side pieces." A gear-wheel, F, on this shaft meshes with a pinion, a, on the main driving-shaft G. This shaft is driven by the pulley H through friction-gears. The-hub K of the pulley is loose on the shaft and ro-v tates constantly. The pinion b is fixed on the shaft G, and next the bearing K is a beveled friction-wheel twin to the bevel face of the wheel b. An idle V friction-wheel, h, is carried on the rear upturned end of a treadle-lever, L L, and when said lever is depressed.

the idle-gear is pressed between the beveled edges of the wheels b and 0, thus communicating the motion of the hub to the friction-gear c and to its shaft, thus causing the cross-head Fig. 3 and in section inFig. 4. ,It turns within a fixed table or case, O,being inclosed within its cavity, and having its flanges o flush with the flanges o of the fixed table. Its 1101- low shaft 1? is supported in bearings on the frame, and ,is provided with a bevel-gear, p, driven by a gear, on the shaft g. This pinion .gears with an elongated pinion, q, loose on the shaft Q, Fig. 5. This shaft receives constant motion from the main shaft, but communicates its motion to q only when The treadle-leq is moved longitudinally to bring the clutch parts 1* together. This is accomplished by means of clutch and locking levers s and s, the latter being moved by hand. The clutch 'is held outof gear by means of a spring, 1,

and is thrown into gear by movement inward of handle of the locking-lever s.- The clutch-lever is pivoted on a stand, 2, and its home the bolt to lock the table, so that both.

the clutch and the locking-bolt are under the control of the operator by means of the locking-lever 8 The table being once started by means of throwing the clutch into gear and withdrawal of the bolt, the end of the bolt (preferably hardened) rides on the periphery of thetable and holds the clutch in engagement without further attention on the part of the operator. half-revolution, the pin drops into its hole, thus permitting the spring 1 to act and release the clutch. Y 7

All that is required of the operator to start the machine when the die is filled is to give the levers a slight movement toward the machine. -When the dies are thus shifted and the unfilled die is in place, the operator presses down the treadle and starts the block, which may continue in motion till the die is filled. In' order to relieve the operator, a

spring-detent, 30, is provided to hold down highest point. e

In this machine, it will be observed, the cutting-die does not change its position during the process of forming a heel-blank. The

\ pasting mechanism has been correspondingly modified. The paste-reservoir R is located on the top of the machine-frame. A tube, 4,

leads down therefrom and communicates with a horizontal tube, 5', on the end of which is a delivery-box, 6. The paste is delivered from the reservoir to this box, which hasholes in the bottomfor the passage of the paste tothe lift. Continuous with the tube 4 is a shaft, 9, stepped in suitable bearing at its lower end, which -is' provided with a .pinion, 10. Into this meshes the segment-gear of a bell-crank down.

lever, 11. Motion is impartedto the bellcrank lever by means of a cam=wheel, 12, on the upper end of a shaft, 13. The lower end of this shaft has a bevel-gear, 14, which meshes into another bevel-gear, 15, onthe shaft E.

The parts are so constructed and timed that the tube 5 will swing to bring the box6 over the cutting-die while the block is rising, and

path of the block when the latter is coming A valve in the bottom of the box is connected to .'a stem, 7 ,sIiding in guides, and When the box has reached its extreme front limit and is directly over the die, the valve is open,

When the table has madca- .having been moved by the end 8 of the stem In order that the hand of the operator may I not be cut orcrushcd by being caught under the block, I have provided a guard, 18, connected by'a spring, 20, toa shaflnt, having its bearings in the cross-head B. It is rocked by means of a pinion, 21, on its upper end, and the segment-rack of a bell-crank lever, 22. The end of this lever projects into auinclined slot'in a plate on the frame, so that the shaft is rocked as the cross-head rises and falls, and

the-arm is thus swung out as the block moves down, and back when it rises.

The wood block 0 is attached to the cross-' bar in such a manner that its height may be varied. It .is 'set directly into a shell, u, and

held-therein by means of a threaded bolt, 23.

The shell is connected to a sleeve, w, by means of a bolt, 24, and nut 25. 'The sleeve 10 has a flange, 0:, formed with inclined faces, which rest against corresponding faces on a flange, y,'on the cross-head. By loosening the nut 26 the flange a: may be turned to adjust the block up or down. The nut 26, when turned down, hold the parts securely together. The cutting-dies are shown in section in Fig. 7.

'Their action is the same as that described in Letters Patent granted E. S. Mansell on the 22d day of August, 1882. They'are designed to cut deck-heels, and the inner die is raised die is fixed upon a similar flanged plate, 28, on

a sleeve, 29, extending down centrally; through the bottom of the tube. Both these flanged die-holders rest on rings or inclined flanges'of a circular plate, 29', which in turn rests on a plate,"30', which forms the bottom of the struct--.

ure. A ring. 31, attached to th'ebottom, incloses and guides the holders. A pin, 32, set in the inner holder, extends through a slot in the outer holder and the guide, and prevents the holders from turning. The plate 29 is provided with asleeve. 33, which extends below the base of the table, "and has a handle .afli'xed thereto and extending to the front, so

as to bein easy reach of the operator.

The flanges or rims ofthe plate 29 are formed with reversed inclines corresponding tb' those of the holders. These inclines are shown in part in the dotted and full lines 34 34 of Fig.

7. All the inclines terminate at their upper and lower ends in plain faces, on which they rest. The plate 30 is held by a pin, 35. The

.plate 29 is turned back and forth, and as it turns in one direction causes the inner die to rise and the outer to fall. Turned in the opposite direction, the motion of the die is reversed. \Vithin the sleeve of the inner-die support is a rod, 37, which projects below the sleeve and carries on its upper end an ejector, 38. This is caused to operate when the table,

in turning, brings the full die near its rear point, when the lower end of the rod rides upon an incline, 42, on the frame, and is thereby lifted. The ejector 38 is preferably of cross shape; but this is not material. An annular plate, 39, having a cylindrical flange, 40, is

placed in the upper end of the cavity or pocket, and rests upon springs 41 41. This forms the plate on which the leather is laid to be cut.

The heel-blanks formed by the cutting and pasting in the dies require sometimes additional pressure in order to render them compact and firm. To do this immediately,- while the paste is still undried, and also to lessen the labor of handling, I have combined a press with the table of the cutting apparatus.

= face-plate of the shaft 54.- This is driven by In the rear of the machine, and a little toward one side, is the press-piston S. It works vertically in suitable bearings in the frame, and is operated by the toggles 49 50 and the bar 51, which is connected by a wrist-pin to a means of pinion 53 from the. pinion q. Thus it is made to operate every time the table the movement of the table.

moves. It is timed in its movement to act in proper relation to the conveyer-arm 55 and The press-pistonbears against a solid die or block, 61, above, preferably cast with the frame, Fig. 8.

In order to prevent the blank from adhering to the press-piston, I provide a plunger,

62, within the press-piston S. The plunger 62 is hardened at its lower end, which.is beveled, as shown-injiig. 9, and bears upon the upper rounded end of the toggle. This is provided with a hardened steel piece, 66, adapted in shape and position to raise the plungerwhen the toggle is moved to lower the pressplunger. fixed a steel cross-piece, 79, which lies in a suitable cavity in the piston-face. At the commencement of the movement of' the table which carries the dies thetog'gle-j oint is moved, the plunger with'the steel cross-piece is held up, when the press-piston descends, and-is thus held for an instant in-contact with the.

blank, while the piston is drawn away .and separated from it. A steel-spring, 65, returns the plunger to its place.

Fig. 8 shows the device for the upper or fixed die. It consists of a plunger, 70, and cross-piece similar to the clearing device for the press piston below. It is operated by means of a bent arm, 69,,and spring 71, which raises the plunger and holds it up. The plun- To the upper end of the plunger is clearer is brought into action just before the admission of a new blank to the press, each blank pushing aside its predecessor. The arm' which pushes the blanks to the press is pivoted on an ofl'set of the stationary part of the table, and is thrown and held back in the position shown in Fig. 3 by means of a spring, 56. (Shown in Figs. 4and 8.) It is thrown forward when the table hasbrou'ght the filled die to its rear or discharge positiomand is consequently within the-sweep'of this arm. The movement is accomplished by means of pins 60 in the revolving table, which are lifted into position to press against the edge of conveyerarms 55 by an incline (not shown) fixed inside of case-O, over which the pin moves during the revolution of revolving table 0-.

It will be observed. that the cutting-dies may be removed from the cavities in the table by taking out screws 60, and single dies may be substituted for the double dies shown in the drawings.

The paster may be taken off, and the machine maybe used to cut lifts of any kind, proper dies of course being used for the purpose. A

A registering device of ordinary construction is indicated at x. by the presser-plu'nger, and register the number of heels formed.
