IMPROVEMENT IN MACHINES FOR ARRANGING NAILS FOR BEING DRIVEN INTO HE ELS Oli SOLES.

0F BOOTS AND SHOES.

Specification forniing part of Letters Patent No. 146,152, dated January 6, 1874; application filed December 3, 1873.

To all whom it may concern:

Be it known that I, JEREMIAH hLWArsoN,

of Sharon, of the county of Norfolk and State of Massachusetts, have invented a new and useful Machine for Arranging Nails for Being Driven into the Heel or Sole of a Shoe or Boot; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top View, Fig. 2 a side elevation, Fig. 3 a front view, and Fig. 4 a longitudinal and vertical section, of it. y

The remaining figures are hereinafter referred to and described.

In I such drawings, A denotes the frame for supporting the main operative parts of the machine. Within this frame there are disposed, as shown, two pairs of inclined rollers, B B O O, the lower pair being below and in advance of the upper pair. Over the upper portions of the upper pair of said rollers is an inclined spout or hopper, D, which is open at its end next the rollers, and at its opposite end is fastened to the frame. Extending within such spout near its lower end is a rotary brush, E, provided with wire teeth, arranged as represented, such brush being fixed upon a horizontal shaft, on. The said shaft is provided with a pulley, b, to receive an endless band, 0, proceeding from and around a pulley, d, on a driving-shaft, F, which is arranged in the frame in manner as represented. The brush,

by being revolved in the direction of the arrow a, serves to prevent the too free discharge of the nails from the hopper. Each pair of rollers, B B G G, are geared together, as shown at e e f f there being on one of the shafts of each pair a grooved pulley, .g or 9 Endless bands h h going around the pulleys g g and pulleys i i on the drivingshaft', serve to impart motion to the pairs of rollers. The hopper D at its lower end is provided with a mechanism for agitating it. This mechanism is shown in side view in Fig. 5, and may be thus explained: Studs k 70 projectfrom the gear f over a lever, Z, pivoted to the frame A. This lever by a rod, m, is connected with an arm, n, extended from the spout, such arm being connected with a post, 0, by a helical spring, 10. During each revolution of the gear f the spout will, by means of it--the lever l, and spring p--be .vibrated up and down. In the outer surface of one or each of the upper rollers B B there 1s;a groove, q, made lengthwise, as shown in Flg. 6, which 1s a side view of such roller. This groove, while the rollers are revolving and have nails between the1n,is to tip a nail into a vertical position in case it should tend to maintain a position parallel, or about so,to and upon the rollers. The bite of the upper rollers or the space between them terminates against a grooved guide or abutment, 0", into which the nails in succession pass, and, by which they are one after another introduced into the bite of, or between,the lower rollers 0 C. There the bite of the upper rollers, a holeor passage, 8, leading to an inclined spout, t, arranged as shown. Waste or imperfect nails, as well as the crooked ones, will be discharged through the passage and upon and by the spoutwithr out droppingbetween the lower. set of rollers.

()11 the hopper being supplied with shoenails, (such as taper from heel to toe,) and the machine being set in operation, the nails will be delivered from the hopper upon the upper pair of rollers, which rollers, revolving in the directions denoted in Fig.1 by arrows b 0 will cause the nails to assume upright positions with their points downward, and to gradually work their way down toward the abutment, from which they will drop successively int-o the bite of the lower rollers G 0. Should the bite of the lower rollers become fully charged with the nails, the surplus passing down the upper rollers will drop out of the machine, the uneven or defective or crooked ones being discharged through the passage 8 in the grooved abutment, a side viewof which abutment is shown in Fig. 7. The box a of the upper journal of the upper roller B should rest against a spring, I), interposed between one end of it and a shoulder, 0 the same being so as to enable the box to move later:- ally, or the roller to give way a little, should any two of the nails get across one another. y

Were it not for such movement of the roller away from the fellow roller, the nails would be liable to become jammed between them,

so as either not to separate or to be productive of injurious. consequences. I

Underneath the lower set of rollers G C Price.

1s, through the abutment r and in line with there is arranged upon a shelf, 29, a set of jaws or nippers, u a, a top view of them being shown in Fig. 8. These nippers are to seize the nails and advance them into a vertical channel, 11, down which they are successively to be driven by a driving mechanism, to be hereinafter explained. It consists, in part, of a driver, Gr, (shown in Fig. 3 and in end view in Fig, 9 and in top view in Fig. 20,) projected from an upright slide-bar, I-I, arranged as represented. A connecting-rod, I, pivoted to said bar H, and to a crankpin, K, projecting from a cam, L, arranged on the driving-shaft, serves to effect the vertical motions of the bar H. From the rear side of the bar H a cam, w, is extended, as shown in Fig. 21. This cam rests against a projection, m, from a lever, y, arranged as represented arid connected at its free end to a spring, 2, fixed to the frame A. The cam is to move the lever backward, and the spring is to give to it a forward motion, in order to enable it to impart like movements to the nippers by means of studs or pinsco a extended up from the said lever into oblique slots 11 b made in the nippers. These slots serve with the pins to open and close the nippers, as well as to aid in moving them longitudinally. Each nipper is provided with a friction apparatus to keep it from sliding too freely. It consists partly of a screw, 0, going down through a washer, (1*, on the nipper, and through a slot in the nipper, and also through the shelf. A helical spring, 0 en compassing the screw, bears against the shelf and a nut, dflscrewed on the screw, as shown. The nippers should be elastic, in order to conform to the nails, as they may vary in thickness.

Fig. 10 is a vertical section of the channel 0), and the nail pressers or devices for holding the nail from dropping out of time into and through the channel 11. These pressers consist of slides f f arranged as shown, and provided with helical springs g, for forcing them up to the nail. Below the channel 1; is what I term the rotary distributer L, which is shown in top view in Fig. 11, in side elevation in Fig. 12, and in bottom view in Fig.13. It consists of two disks, k i connected by a shaft, 1 The upper disk is perforated with a range of holes disposed in a circle, and the lower disk has a corresponding number of holes arranged as the nails are to be when inserted in a heel or in the nail-carrier X, a top view of such carrier being shown in Fig. 14. Each of the holes of the upper disk IL3 is connected with one of those of the lower disk i by one of a series of tubes, 70. Furthermore, there is a notch, 1 made in the lower disk 1' from its periphery, and there is fixed 011 the shaft 6 above the upper disk, a ratchetwheel, m. A

bent lever, n carrying an impelling-pawl, 0, is arranged so as to turn freely on the shaft and above the ratchet-wheel. The distributer is supported within and by a tubular standard, M, in a manner to enable such distributer to be freely revolved horizontally. The tubusaid arm a belt, 19, which proceeds from a friction-pulley, q, arranged to turn upon the driving-shaft F. Pivoted to the bent lever n is a rod, 0, which is also pivoted to the upper end of a lever, 8, arranged as shown, and pro- I vided with a spring, 15 for pressing it against the cam L, hereinbefor'e mentioned. During each revolution of the cam, the lever s, the spring t the rod 4*, the lever n pawl 0, and ratchet-wheel m will effect one movement of the distributer, which distributer will remain at rest for a time, in order to receive a nail. As the nails pass into the distributer, they drop through its tubes and rest upon the disk 0. After'the distributer may have received its full complement of nails, it will stop revolving, such being caused by mechanism to be next described. 7

Fig. 15 is a horizontal section of the machine, taken through the distributer, so as to show the driving-shaft and mechanism in'the lower part of the frame.

A catch-lever, u, (shown in top view in Fig. 16,) is to operate'with the notch l to stop the distributor from revolving. This catch-lever is pivoted to the frame A, and to the sliding part c of a clutch,'B, carried by the drivingshaft F. The cam L, although onthe driving-shaft, is fixed to such sliding part c, so as to be revolved by it when in engagement with the fixed part 20 of the clutch. There is a cam, S, fixed to the cam L as shown, and underneath a lever, T, disposed as represented. The free end of this lever is fastened to a spring, as, whichoperates to draw the lever downward. The said lever carries a foot, a from which a cam, 3 (shown more particularly in Fig. 17, which is a transverse and vertical section of the lever with the cam'attaehed,) projects. This cam is to actuate the lever-catch u in one direction, or force it back, a spring, 2, arranged as shown, serving to move it in the opposite way. The foot a that projects down from the lever T rests upon a yielding slide, b arranged as shown, and provided with a spring, 0 to force it forward.

Furthermore, there is disposed underneath the shelf N a bent lever, (1?. (Shown in under side view in Fig. 18.) From one arm of said lever a stud, 0 projects up through a short slot, f made in the shelf. The other arm of the lever d is pivoted to a slide-rod, g ,'provided with a spring, 71/2, for forcing it forward. (See Fig. 2.) The said rod has projecting up from it a fork, i that entersa groove, It, made in and around the friction-pulley q, hereinbefore mentioned. To. co-operate with and revolve the pulley q, there is fixed on the driving-shaft a disk or friction-wheel, 1 In advance of the nail-driver G, and fixed to the frame A, is a spring, U, formed as shown in Fig. 3, and in end view, as represented in Fig. 19. The spring U serves to force the nail- .driver G (shown in top view in Fig. 20) out of the nail-passage preparatory to each ascent of the driver, and to keep it out thereof until it may have arisen above the nail next to be driven downward by it. In front of the yielding slide 1) is a stationary stud or short post, m erected on the shelf N. After the distributerL may have been supplied with tacks, the

nail-carrier X (shown in Fig. 14) is to beplaced 011 the shelf N, and underneath the disk 0, and so that the stud or post m may be straddled by the fork n of such carrier. This having been done, the carrier is to be moved aside upon the post as a fulcrum, and against the stud e of the lever at, so as to move said lever, and thereby cause the friction-pulley q to be borne up against and revolved by the disk P. This will cause the belt 19 to be wound on the pulley g whereby the disk 0 will be moved laterally from underneath the distributer L, so as to allow the nails in the distributer to fall out of it into the ranges of holes of the carrier. On withdrawing the carrier charged with the nails, the disk 0 will at once be returned to place underneath the distributer,

which will beunlocked, and next will be again intermittently revolved and charged with nails. On applying the nail-carrier X to the stud m i such nail-carrier is to be pressed against the yielding slide 12 so as to force it backward from underneath the foot a of the lever T, and allow such foot to rest on the carrier. On withdrawing the carrier the lever of course will be drawn downward by its actuatingspring, and the cam projecting from the foot will operate or move the catch-lever, so as to unlatch the distributer, and throw into en gagement the parts of the clutch by which the mechanism for turning the distributer is put in action. From the above it will be seen how shoenails, after being put into the hopper of the machine, will be dropped therefrom upon the upper pair of inclined rollers B B, and by them arranged points downward, and delivered to and between the lower pair of rollers, and fromthem be delivered successively into the vertical nail-receiviu g passage, and driven therefrom into the distributer, and, finally, discharged therefrom into a carrier for being inserted in or applied to a heel.

1. The combination of the grooved guide or abutment r and the two pairs of inclined rollers B B O O, arranged and applied together,

as and for arranging and feeding shoe-nails, as set forth.
