SPECIFICATION forming part of Letters Patent No.44'7,317, dated March 3, 1891. Application filed September 12, 1890. Serial No. 364,736. No model.)

To all whom it may concern/.- Be itknown thatI, J OHNA. HALL, of Union, in the county of Carroll, State of New Hampshire, have invented certain new and useful Improvements in Heel-Making Machines, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a side elevation of my improved machine; Fig. 2, a front elevation of the same; Fig. 3, a rear end elevation, the shaft being shown in section; Fig. 4, a vertical transverse section showing the cutting-die and plunger; Figs. 5 and 6, plan views of the nail-plates; Fig. 7, a bottom plan view of the nail-plunger; Fig. 8, a bottom plan view of the driving-plunger head; Fig. 9, an elevation of the nail-wire support; Fig. 10, a top plan view of the same; Fig. 11, a top plan view of a portion of the base; Fig. 12, a plan of one of the completed heels, and Fig. 13 a sectional elevation illustrating the nail-rods and supports in operative position.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates especially to machines for cutting and nailing shoe-heels; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, represents the body or base of the machine, upon which a vertical standard 13 is mounted, said standard being provided at its top with two earsO, in which a horizontal shaft D is journaled. A loose gear E is mounted on the rear end of the shaft 1) and is provided with spokes b. The rim of the gear is provided near the outer end of each spoke b with a radially-arranged socket Z.

being in position to engage the arm 71 of the rod g. A t-readle H is pivoted to the floor between the bed A of the machine, and a vertical treadle-rod j passes through said bed, the upper end of said rod being connected by a pivoted curved bar 76 with the upper ends of the lever 11. Said bar is slotted at land plays on a pin m in said standard. A horizontal driving-shaft p is mounted in the rear of the standard B and bears a driving-pulley q and a pinion 0", which meshes with the gear E. Between said pinion and drivingwheel a rod if is mounted and driven vertically by an eccentric Q; on said shaft. A horizontallyarranged cutter-lever w is pivoted to the bottom of the base A, its rear end being pivoted to the rod t. The forward end of said lever is provided with a knife (shown in Figs. 1 and 2,) which engages the under side of the base A, said base forming a cutterblock therefor. A guard-rail z is secured to the base of table A around said knife, said knife being employed to trim the. stock from which the heel is formed. On the forward end of the shaft D a crank-disk 15, provided with a crank-pin 16, is mounted. A vertical plunger-rod 17 is fitted to slide on the stand ard B, its upper end being connected by a pivoted lever 18 with the crank-pin 16, and

. its lower end being provided with a head 19,

provided with a metal face 20. A hollow eutting-die 21 is provided with a cutting-edge 22, said die being of a shape suitable to form the heel. One face of the die is provided with a vertical slot or opening, at theedgesof which are gage-marks 24.

table A is provided with an opening 25 ,(shown in Fig. 11,) and above said opening a steel wear-plate 26 (shown in Fig. 5) is disposed, said wear-plate having a central circular opening 27, around which are arranged three (Shown in Fig. 2.) The IOO radial openings 28. A plate 29, (see Fig. 6,) provided with openings 30 and 31, adapted to register with the corresponding openings in the plate 26, is disposed on said plate 26 and supported by adjusting-screws 32, whereby said plate may be leveled. A block 35, having a head fitted to slide in the die 21, is provided on its lower end with a spindle 36, which works in the openings 27 and 30 of the

plates

26 and 29. An arm or pointer 38 on said block projects through the slot 23 of the die, the position of said arm in relation to the gage-lines 2% determining the thickness of the heel being formed. A curved lever 40 is pivoted on the machine-frame, the head 41 thereof projecting into the opening 25 of the table A, into engagement with the spindle 36 of the block 35, said lever being counterbalanced suificiently to support said block. The block is provided with a series of vertical nail-openings 45, in which verticallyarranged stiff steel rods or wires 46 (see Fig. i) are fitted to slide. Two adjustable stops *7 are respectively secured to the tableA by set-screws, (see Fig. 2,) said stops prevcntinglateral movement of the die 21 when in use. A guard I (shown by dotted lines in Fig. 1) may be arranged around the plunger-head 19 and die 21, if desired. A screw-plug 50 (shown in Fig. 9) is disposed below the opening 25 in the table A, (see Fig. 13,) beneath each wire 46, said plugs being adjustable vertically in said table. A circular plate 51 is pivoted to rotate on the top of each plug 50, and is provided with a radially-arranged slot 52, in which the lower end of the wire l6 rests, said plate permitting a slight lateral movement of said wires.

In the use of my improvement, the die 21 being adjusted, as shown, and secured by the steps 47, nails 55 are inserted in the openings 4:5 of the block 35 with their heads resting upon the upper ends of the wires 46. The shaft 19 being in motion drives the shaft D geared thereto, operating the plunger 17 and forcing its head 19 against the cutting-edge of said disk. The eccentric-rod t, driven by the shaftp, operates the knife 11 by which the stock is first trimmed. Said stock is then disposed by the operator onto the cutting-edge of the die 21, and is driven by the plunger 19 into said die and onto the nails 55, the points of said nails as the first lift of the heel is thus laid onto the die being flush with the cutting-edges thereof. As succeeding lifts are disposed on the die and cut by the plunger, the block 35 is depressed thereby, the wires 16 still supporting the nails and cansing them to bedriven through the succeeding lifts. The arm 38 on said block indicates to the operator when a sufficient number of lifts have been cut and attached, as described hen the heel is completed, by depressing the treadle H the operator throws the shipping lever 11 into the path of the arm 7L of the rod 5 causing said rod as it strikes said lever to be withdrawn from the socket I) in the gear E, which now works loosely on the shaft D, stopping said shaft and the plunger. By depressing the onter end of the lever 40 the block is forced upward in the die 2l,ejecting the heel therefrom. Scraps or small pieces of leather may readily be employed with this device in forming the heel is, the operator holding the edges of said pieces together over the die. By means of the index on the die, the sizes of the nails being known, the number of lifts in the heel may be so accurately regulated that the top lift may be attached without removing the body of the heel from the die. The

openings

28 and 31 in the

plates

26 and 29 being radial allow for the spring of the rods 46 under the blow of the plunger. Said plate 26 serves to prevent wear on the adjusting-screws 32 on the table of the machine. 13y removing the block and

plates

26 and 29 and wires 40 the die 21 may be employed to cut heel-lifts, which fall therethrough and through the opening 25 of the table A.

Having thus explained my invention, what 1 claim is- 1. In a heel-making machine, the combination of a body provided with a table, a hollow cuttingdie disposed on said table, a plunger sliding in said body above said die, a crank-shaft connected with said plunger, a gear-wheel E loose on said shaft, provided with sockets (l, a driving-shaft provided with a pinion meshing with said gear-wheel, aboss fixed on said shaft and provided with a tubular arm f, a rod g, adapted to slide in said arm to engage said sockets and provided with a lateral arm at its inner end, a.shipping-levcr 1', adapted to engage said arm for withdrawing said rod from the sockets, and means for actuating said shipping-lever, substantially as described.

2. In a heel-making machine, the plug 50, adjustable on the machine-body, in combination with the lever-supported block 35, fitted to slide in the cutting-die and provided with nail-openings 45, and the rods 46, supported on said plugs and working in said openings, substantially as described.

3. In a heel-making machine, the combination of a crank-actuated plunger, a hollow cutting-die provided with a gage-opening, a lever-supported block fitted to slide in said die and having an index projecting through said slot, and nail-rods mounted on adjustable supports and working in openings in said block, substantially as described.
