IMPROVED MACHINE FOR MAKING NAILS.

tin tlltbltlt numb tn in tlgrsc fitters than nit mulling tint at ilgt 5min TO ALL WHOM IT MAY CONCERN- Be it known that I, JACOB RUSSELL, of the city of Brooklyn, in the county of Kings, and State of New York, have invented a certain new and useful Improvement on Machines for Cutting and Heading Hails, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawing, forming part of this specification, and in which- Figure 1 represents a side'clcvation of a. nail-cutting and heading machine constructed according to my improvement.

Figure 2, a central longitudinal vertical section thereof.

Figure 3, a plan of the same; and v Figure 4, a transverse vertical section of themachinc in part, taken as indicated by the line re re in fig. 1.

Like letters denote corresponding parts throughout the several figures.

The nature of this invention consists ina novel combination in a nail-cutting and heading machine, with a straight or direct nail-plate feed, of cutters, nippers, grippcrs, and headers, arranged for operation together on aframe or bed, having an oscillating movement about an axis perpendicular, or nearly so, with the horizontal clipping edges of the cutters; and said invention further consists ina peculiar arrangement of the nippers relatively to-the cutters and headers in nail-cutting and heading machines, and operating to turn the cut blank by striking it at or about the middle of its length on to-its flat prior to its being gripped for heading; also, in so operating headers on opposite sides of the feed as that by giving them, in addition to their heading action, a united oscillating movement in a crosswise direction relatively to the feed, the blanks are successively acted upon by the opposite headers alternately.

Referring to the accompanying drawing, A represents the base of the machine, on which rests or over which is arranged a horizontal frame, 13, that is so hung or supported on a vertical, or nearly so, shaft or axis, G, as to be capable of oscillating horizontally The lower frame or base A, which is stationary, carries at its forward end, by uprights a a, the nail-plate feeding table D, which may be set inclining downwardly towards the cutters S S, and slide through grooves in the uprights, so as to be adjustable relatively thereto. The upper frame B carries, by suitable uprights or supports, the several operating parts of the machine, including the cutters, nippers, grippers, and headers that, in addition to their several or respective motions, have a horizontal oscillating movement in common with the base 13 on the axis 0, which latter-may be described as perpendicular, or nearly 'so, to the clipping edges of the cutters. This oscillating movement serves to vary or reverse the action of the cutters, so that, in their cut across and through the nail-plate as it is fed down or along the stationary table D, they will alternately, as they are oscillated from one side to the other, out in oppositely tapering directions, thus giving the nail blanks their required taper without oscillating or turning the plate out of which they are made. The nail-plate E, shown by black lines in fig. 1, and by red lines in figs. 2 and 3, is fed down or along the table 1) through a forward guide, I1, up to and for action on it of the cutters by dogs 0 c, that book through a slot in the fecd-table, on to the rear ends of the plates, and urge them forward by cords and weights, d. But one of these dogs may be in action at a time, or they may operate on separate plates simultaneously, one in rear of the other, for short ii'itcrvals, each dog, after having urged its plate a certain distance, being tripped by coming in contact with an inclined plane, 0, when the succepding plate in the rear will continue, by the action of its dog, to press forward the remaining portion of the first plate, till the whole, or nearly the whole, of it is utilized or cut up, and so on for any number or series of plates, one following up the other. The one cutter, S, is carried by a block, F, attached to or forming part of the main oscillating frame 13, while the other cutter, S, is secured to a head-block, forming part of a cross-roeking beam, G, that is hung by bearings, f, in supports on the frame 13, and has arms or levers, 9, running backwards, by which the cutter S has its up" and-down motion given it to effect the cut by the rocking of the beam G through pitman 7%, connecting said arms or levers witlrcranks or eccentric-pins, 2', attached to or connected with a main driving-shaft, H, of or to which I may be the driving-pulley. In rear of the cutter S are arranged springs d J, which may be constructed to serve as gauges to the nail-plate, or separate gauges may be provided, but which serve, as the nail blank j is I cut, to hold it till and whilsta nippcr-rod, K, comes forward, and, catching the blank near its lower edge, turns it over on to the flat for the proper formation of the head and grasp. of it by the grippers. After thus turning the blank, which is done by striking it at the middle of its length or thcreabouts, so as to avoid tipping up of the blank cndwise, said nipper-rod forms a rest, in conjunction with the springs J J, for the blank, till the gripper 01' grippers L get hold of it, said grippers being divided, and the nipping-rod K passing centrally thercthrough. So soon as or immediately after the grippers have got Fair hold oi the blank, either one ot' two headers, M M, according to the side to which the whole working mechanism is oscillated relatively to the nail-plate, is brought to bear against the head of the blank and forms the head, after which, the grippers and nipper having retired, the headed nailvdrops below.

It will be obvious that as the cutters oscillate on an axis, C, across the nail-plate, which is stationary in relation thereto, not only is the'cut established in oppositely tapering directions, and so the turning or oscilla tion of the plates avoided, but that each blank cut will,bfthe oscillation of the cutters, be delivered or fed into the machine alternately in closer proximity to the one header than the other, and the thickest end of the blank adjacent to the nearest header, so that, though the two headers may simultaneously make heading strokes, only one of them can operate at a time on a blank, and each one alternately. The nipper-rod K, acting as described, may be operated by a lever, N, and yoke-rod O, worked by a cam, P, on a connter-slmi't, Q, deriving its motion by gear 70 is from the main shaft H, to project the nipper-rod forward, while a spring, u, may be employed to draw it back when relieved from thrust on it by the cam. The gripper or grippers L may also be similarly operated by means of a lever, s, hung on a fulcrum shaft, Z, and acted upon by a cam, V, on the main shaft, and

' be drawn back by the spring in. The headers M M may have their reciprocating motion given them to effect the hcading'of the blanks, as they, in common with the cutters, nippers, and grippers, oscillate with the frame 13 by means of levers T, to which said headers are attached or form part, said levers being' secured to rockingbars U, working on pivots or bearings r, and being acted upon by lifters u, through projections 0, on the cutter rocking-beam G, which, as it vibrates, will, by the connection described, give the necessary reciprocating or heading action to the headers. It is almost unnecessary to observe that the cams and other contrivances which give motion to the cutters, nipper, gripper, and headers are so pitched or arranged relatively to each other as to secure to each of these functional devices its proper and timely action, as hereinbcf'ore described.

,What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a stationary nail-plate feeding table, or its equivalent, of cutters, nipper, gripper, and-headers, arranged for operation together on a bed or frame having an oscillating motion about an axis perpendicular, or nearly so, with the horizontal clipping edges of the cutters, substantially as specified.

2. The arrangement, relatively to the cutters and headers, of the nipper K, operating to turn the blank by striking it at or about the middle of its length, essentially as herein set forth.

3. Imparting to theheaders M M an oscillating movement in unison towards and from opposite sides of the nail-plate feed, in addition to their heading motion, by means substantially as shown and described.

JACOB RUSSELL.
