IMPROVEMENT IN MACHINES FOR NAILING BOOTS AND SHOES.

v Specification forming part of Letters Patent N 0. 169,661, dated November 9, 1875; application filed I February 5, 1875.

To all whom it may concern:

{Be it known that I, FRANCIS M. SHAW, of Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Machines for Nailing Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. 1

In the said drawings, Figure 1 is a side elevation, and Fig. 2 a top view, of anail-driving machine embodying my improvements. Fig. 3 is a detailed sectional view of the headstock, the cross'head, the driver, the drivertube and spring nail-retainers, the nail-re ceiving tube, and showing sundry parts adjacent thereto. Fig. 4 is another detailed sectional View taken through the awl-stock, thcawl, the driver, driver-tube, and nail-retaining jaws. Fig. 5 is another detailed sectionalview, showing the screw-transferrers, their connecting-gears, and the arrangement of the said transferrers with respect to the nail-receiving tube. Fig. 6 is another sectional detailed view, taken longitudinally and vertically through one of the nail-reservoirs, and showing the parts immediately adjacent thereto.

My invention may be said to be an improvement upon the well-known automatic peggingmachine; and consists in dispensing with the mechanism for holding, severing, and feeding the peg-wood, and substituting therefor mechanism, as hereinafter described, whereby the machine is adapted to thedriving of headed nails, the nails being conveyed from one or more reservoirs, carried to and inserted in the soles of boots and shoes automatically.

In the drawing, A denotes the base or frame the driving-shaft; O, the head-stock, which is securely afiixed to one end of the frame. D is a cross-head, which slides horizontally on the he ad-stock"G. E. is a block, which slides vertically in the cross-head D. This block E has the awl-stock that carries the awl at nectedwith the head-stock O is a frame, G,

which is securely bolted thereto, and carries the nail-feeding mechanism, next to be described.

Pivoted to the frame G, at H H, is a rocking frame, I, which, at its rear part, supports two elevated frusto-conical nail-reservoirs, J J, each having one or more flanges or radial shelves, 0,, upon its inner surface, as shown in Figs. 2 and 6. K K and K K are inclined slotted barsor ways affixed to the frame I, and respectively extending up into the interior of the nail-reservoirs, as shown in Fig. 2, a portion of the reservoirs being broken away in order to exhibit the same. These ways are formed with beveled inner edges to receive the nails, and support them by their heads while traveling down the ways. The lower end of each nail-reservoir has a wide elastic head, 0, of rubber or its equivalent, inserted therein, such having a hole made through it of sufficient size as to allow the ways to pass through it, and also the nails, when suspended in the ways by their heads. An elastic washer, d, is firmly secured against each elastic head by a retaining-block, e,

affixed to .the ways, as shown in Figs. 1, 2,

and 6. Each of the said ways is so arranged as to operate with the stationary sectional ways ff affixed to the frame I, as shown in Figs. 1, 2, and 5, and by simply moving the rocking frame I either to the right or left either pair of the movable ways may be brought, as circumstances may require, into alignment with the stationary ways. The employment of thetwo reservoirs is to enable nails of different lengths to be used, as may be desirable, without stopping the machine or changing the reservoir, as would be required were the machine provided with but one inciined way.

Supported in suitable hearings in the frame. G is a shaft, L, which extends horizontally. of

the machine, and has on its front enda male screw,--g,- whichoperates'with another screw,

g,-i1w.hich. is supported in bearings in. the frame an arran er in e same lOIlZOll a J ane G, d g 1 th 1 t 1 1 with the screw g, and in such close relation therewith as to permit their threads to rotate withouttoncliing, the two threads being cut tance apart as to receive and support the heads of the nails between the two. These screws .are. connected by gears s 3, (having a like number of teeth, as shown. in Fig. 5,) such screws being disposed in front of the stationary ways f f, and receiving the nails between themas they drop from" the said ways. These screws have not their threads extending to their extreme outer ends, but terminate at a point in a vertical plane over a -hollow receiving-tube, M, which is affixed to'--the"front "end-0f the frame G, and intowhich the-nails successivelyd'rop when released from the-threads of the screws. The' rotation of the screws 'is' effected by a spurgear, l, 'on"the shaft L, which engages with a gear, m,:disposed on the driving-shaft, each -of the'gears land m having a like number of teeth, iuorder that the "shaftL an'd the driv in'g -shaft shallperform alike number of revolutions, and thereby cause the screws to' v make a-single revolntion', and discharge a nail. at each revolutionof the driving-shaft, a h olebein'g made in the sole, the sole fed along, a'ndthe. driverra'ised and forced downward at each revolution'ofthe driving shaft.

.gDi'sposed nearone end of the shaft L is a friction-wheel, N, which is so arranged as to bear against the surface of either of th'enailreservoirs,'as'may bedesired, and serving-to:

impart rotation'nthereto, and thereby raise the nails which may lodge on? the partitions,

which,;-'when'the latter shall have been raised into a verticalposition over the ends of the inclined ways, will deposit more or less of the nails thereon. The? tube M, having its mouth directlyiunder J the discharging end 'of the screwtransferrersg g, extends down and opens into. thedriver-passage 4 near its upper end at aslight inclination thereto, such driver-passage ,b'ein g formed-in a toe, a, which isaffixed .to' the under'part of the head-stock 0;. do areitwo. spring-retainers,'which are affixed to the toe-part n, the same being formed .w-ithli'ps to extend down and close soleqiritowhich the nails are to be driven conin "opposite directions, and being of such dis- EGQAEGK stitutes no part of my invention, I would remark that'the jack employed-in the ordinary automatic pegging-machine may beused, or any other suitable for the purpose, as the support and guiding ofthe boot or shoe, whether being pegged or nailed, are precisely similar.

Having described my invention, its opera tion is as "follows: If we suppose the reservoirs to have been supplied with nails, and thedriving-shaft to have been put in revolution, the friction-wheel N will cause the reservoir with which it is in connection to rotate, and, when its shelves have been brought to their highest point andover the forked ways, will discharge the nails therefrom, a part falling on the ways, and will, by the concussion of the driver, be caused to fall between the ways, and be suspended therein "by their heads. Should any fall sidewise upon the ways upon reaching the opening in the rubber head, the

latter, by-impinging against the same, will,

by its rotation, remove them laterally-from; the'ways, while'the nails properly suspended by their'heads in the ways will be caused, by the continued concussion of the driver, to passdownthe ways K'K or K" K into the sta-' tiona'r'y ways f f, from which'they'will pass" into the screw-transferrers,by which they will be carried forward, and a single one at a time dropped into the mouth of the tube M, or into the nail-passage in the toe n, the action of the screws and the-driver being so timed that the nail shall be dropped into the tube when the) driver is down. The point of the nail, im-' pinging against the side of the driver, will be;

retained thereby until the driver vis raised, when the nail will drop' into the driver-passage in the toe a, where itwill be retained the spring or retainers until the driver shall next descend,'wh en the nail will be driven into the sole; 7 Y

I I would remark-that, if desirable, a single arrange the frame G that the nails, when discharged-'from' the screw -transferrers, shall drop directly into the nail-passage win the toe n. a Y 7 e WhatI claim as my invention 1s- 1. In a machine for nailing boots and shoes,
