To @ZZ whom t may concern:A Y

Be 1t known that I, JOHN J. HEYS, of Lynn,

Y in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Heel-Pressing Machines, which will, 1n connection with the accompanying drawlngs, be hereinafter fully described, and specltically defined in the appended claims. ln sald drawings Figurel is a front elevationof my machine. Fig. 2 is a side elevat1on taken at the left of Fig. l. Fig. 3 isa vertical sectional elevation on line Z, Fig. 1. F1g. 4 1s ahorizontal sectional plan view taken on l1ne X, Fig. 2. Fig. 5 isa detail sectional view.

The object of my invention is to automatically feed the cut and nailed together heels of b oots and shoes to an automatic pressing device constructed and arranged to press the heel blanks on every side; which next delivers the blank out of. the machine by the act of admitting another blank to the pressing devlees.

The invention consists in a machine ernbodylng divers devices and combinations thereof which will be next herein described in connection with the accompanying drawlngs, and then defined in the appended claims.

Referring again to said drawings,A A represent the side frames of my machine, which are formed of cast-iron of adequate size andY strength, and which at the front are reinforced by the wrought metal rods B B which are inserted in hollow bosses of the frame and at thelriends are secured by nuts, as shown. Said side frames are united by the cross girts C C, which also engage said rods B B, and the girt rods D D, as shown. A pinion shaft a Journaled in the lower portion of the machine carries a pinion h that meshes with and drlves gear c, it being itself driven by a belt on pulley CZ shown in part in Fig. 1 and fully 1n Fig. 4. Said gear c is mounted on crank shaft e, which shaft impels pitman f which at lts opposite end is connected with pivot rod h that is arranged at the meeting ends of knuckle joint g g, which at its lower end is pivoted to lower girt C, while at its upper end 1t1s pivoted to cross head 'i which it causes to move up and down as it is crooked and straightened through pitman f and crank shaft e as rotation of the gears takes place.

'Upon cross head c' are arranged the curved 4 molds j 7' that press the side and rear edges of 55 the heel blanks. Saidmoldsj are pivoted by links 7cto rods B, so that when the cross head isin its depressed position said link draws the molds farthest apart and when it is in its most elevated position the` molds will be 6o nearest vtogethenthey sliding on the cross head and thus alternately compressing the heel blank and then releasing it. The top side or plane of the heel blanks is pressed by the broadened end of die w the stem of which is inserted invtop girt O Where it is secured by set screw v2, and the breast of the heel bears against the shoulder at the intersection of arm m and carrier Z. The heel blanks are carried between the halt dies 7' by carrier 7o Z extended from arm m pivoted at n to a projection p extending from cross head il; while an extension t of arm m passes below pivot n and carries a trundle that enters the curved slot q cutin the lside of block 3, secured at l.the front of the machine.

The office of said groove and the engagement of the trundle ot projection t therein is that as the cross head rises the arm m will be swung on pivot n to the rear, and the part t will move to the front; 8o

and the reverse movement occurs when the cross head is lowered. The heel blanks are held and delivered to the molding dies by a trough-like piece, 4, supported by cross head i', which piece has an upwardly extending 85 slide downward as the bottom one is removed 9o from the stack onto carrier Z.

To move the bottom heel blank from the stack in angle plate 6 to carrier Z, a rock shaft 7 is journaled to the side of the machine and on the rear end of said shaft is secured arm 9 5v 8, carrying trundle 9, that travels in the cam groove in the periphery of wheel 8 secured on crank shaft e; an arm 11 is secured to the front end of shaft 7, and rising above trough 4, it carries a pitman 12 that isconnected roo with and reciprocates expeller 13 sliding in trough 4c, which travels just far enough to force the bottom heel blank onto carrier Zand thereby forcing ofi" the preceding blank that had been pressed. A chute 14 is so arranged that it receives and conducts away the heels as they leave carrier Z as already explained.

As the strain on cross headvl is considerable, I extend an arm 16 therefrom to the rear, and in this arm I secure the rod 15, which passes through arm 17, also extending to rear from upper girt; C, so that said rod will slide therein and Will aid in holding cross head t' 1 true and level at all times.

The molds j can be formed separate from the main part that is pivoted by links 7.5, so that when it is requisite to change to a larger or smaller size of heels it will only be necessary to change the mold proper, leaving in the part so pivoted. The recess in cross head ris Somewhat larger then carrier Z and on said carrier is removably secured a plate 18, which will be changed as different sized heels `are to be pressed; said plate, when lowf ered, resting on cross head 't' and being in 1 closed by the molds when molding the heel.

Among the advantages of my machine are the facts that the fingers of the operator are never nearer the molds than when stacking 1 the 'heels inthe crib; so that there is no possible danger of mutilation; and by such sys- 1 tem of feeding a number of heels to the machine at the same time one boy can tend two or more machines, and if desired, the ma-` chine may be made duplex; that is two machines run by the same belt, so as to bring both machines into as small a compass as possible, and in such case one machine would be arranged to be under pressure when the heel in the other was liberated.

In Figs. 2 and 5 the arbor 7, Whereit passes through the hub of arm l1, is shown by dotted lines as formed conical; and a pin 19, is i rigidly inserted in said arbor; While the hub of arm 11 is formed with a slot 20 cut through its shell to receive said pin; in order that if arm 11 should meet with undue resistance said arbor could move in its hub to the distance required by cam 10, and so remain till arm 11 is liberated.

I claim as my invention- 1. In a heel pressing machine the combination of pinion b duly rotated, gear c on crank shaft e impelled by said pinion, pitman f driven by shaft e and arranged to actuate knuckle joints g g; cross head c', molds j j, top mold w, and carrier arm 'm with carrier Z, all substantially as specified.

2. The combination of sliding molds jj, top mold w, the rising and falling cross head and carrier Z extended from pivoted arm m., substantially as specified.

3. In combination with cam 10, and arm S, thereby driven, the arbor 7 impelled by said ,cam and its arm and the arm 11,carrying expeller 13, and secured to said arbor bya conical bearing and a pin inserted in a slot in its 1 hub; whereby said arbor can move when arm 1l, is held fast, substantially as specified.

4t. The die blocks j pivotally attached and resting on the moving cross head overhead mold w, carrier l, arranged to fit in a cavity in cross head t', arm m and block 3, formed with groove q to receive the trundle of said arm, all substantially as specified.

5. The combination with the molding de vices of expeller 13 connected by a pitman 4With arm 11, said arm, the rock shaft 7, arm

substantially as specified.
