JOHN WOOT'ION, OF BOONTON, NEW JERSEY.

NAIL-MACHINE.'

To all whom t may concern.'

Be it known that I, JOHN VVoorroN, of Boonton, in the county of Morris and State of New Jersey, have invented a new and Improved Machine for Making Nails and Spikes; and I do hereby declare that the following'is a full, clear, and exact description of 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, is a longitudinal vertical section of the same. Fig. 3 is a sectional plan of the same in a plane passing through the center of the working parts. Fig. 4, is a front view of the rolls. Fig. 5, shows the description of nail or spike produced by the machine.

Similar letters of reference indicate corresponding parts in the several figures.

This machine is intended chieiiy for the purpose of manufacturing square nails or spikes tapered on all sides to a point; an operation which has never to my knowledge 26 been successfully performed by machines which eifect the drawing out or tapering by means of rolls. My invention consists in a certain combination and arrangement of rolls whereby spikes of the above form or 30 other forms can be manufactured in a very perfect manner.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, is the framing of the machine. B, B, are two feed rolls having V shaped groo-ves, which when united form a square. These rolls receive from the main shaft C, through the united agency of a crank on the said shaft (not shown) a hooked rod, E, connected therewith and a studded wheel, F, on the lower roll, an intermittent rotary motion; the distance of each movement being sufricient to feed through a suitable quantity of the rod (a) of iron, from which the nails or spikes are to be made, to make one nail or spike. every feed by means of a stud on the side of a lever (g1) which works on a fixed fulcrum v on the framing the said stud entering Y one of a series of holes in the side of the wheel, F, but at the proper time for the feed the stud is withdrawn by the action upon the lever (g) of a cam (7L) on a vertical shaft,

O. Close behind the feed rolls are a pair of shears (Z), the lower portion of The rollers are held secure after which is stationary, but the upper part 1s suspended from a lever, G, at the top of the machine which receives a motion from a` cam, H, on the main shaft, C, in such man-` ner and at such intervals, that immediately after each feeding movement of the rolls ceases, a piece of the rod (o) which has been seized between a pair of rolls, I, I', whose shafts J, J, occupy a vertical position side by side in the machine. i

The condition of the machine represented in Fig. 2, is that when the shears have just cut off the piece. The rolls I, I', have taper V shaped grooves (c, c) which as the rolls move in contact with each other form a die whose transverse section is a square, the size of the back part of the said grooves being such as to receive the full size of the rod (a) and the front part terminating nearly in a point. The dies are geared together by toothed segments (d, ci.) and receive a reciprocating circular motion through a crank K, on a vertical shaft O, which gears by bevel gearing with the main shaft C, and a connecting rod, L, connecting with an arm, M, on the shaft of the roll, I'. The rolls I, I', receive the piece of rod as they move forward, and as they retreat, draw it out nearly or quite to a point, but can not be made to leave those corners which have been formed in the angles of the dies without fins or feathers, and therefore another pair of rolls, N, N', similar to I, I', are employed to finish the drawing and pointing of the nail, the latter rolls being immedi* ately behind the first, but having their shafts e e, placed horizontally in the machine one a ove the other so that the position of the nail in them, is the reverse of what it was in the first rolls, and the corners which were formed in the angles where the rolls I & I unite will be in the backs of the grooves of the rolls N N and the fins, feathers, or rags left on the corners by the first rolls will be rolled down. The rolls N, N' are geared together by toothed segments (e, e) and have like I, I a reciprocating circular motion, which they receive from a crank, P, at one end of the main shaft, C, and a connect-ing rod Q, which connects the said crank with an arm, It, on the shaft ofthe lower roll N'. The rolls N, N', move back at the time the rolls I, I', move forward, and thus when the latter have finished their operation the former seizes the blank and takes it from them and immediately after commences to tion and heads it. VThe arrangement -andv manner of operating the header is the same as in many otherfmachines it being attached to a lever, X,.which is attached by a cam, Y, on the main shaft. l

The main shaft, C, receives rotary'motion by'spur gearing from a shaft (j) which is driven by anysuitable motive power.

It will be observed onreference to the drawings that in this machine the rolls'instead of being as in the nail and spike machine in commonuse employing rolls, complete cylinders, a're only segments of cylinders, and the length of their surface in the directionof theirmotion is only about equal to the length to which they draw out the nail or spike. The object of thus making the rolls of segments is, that they may be so arh ranged as to allow those, N, N, to take the partly finished nail or spike from` those I I which could not be done by cylindrical rolls as it is necessary that the rolls N, N when thrown forward to receive the partly finishedl nail or spikeshould beV opposite those I I as shown in Fig. 3. `Neither could this be conveniently effected by the segments with a rotary motion and for that reason I give them a reciprocating motion upon their aXes of an extent only just suiicientto produce the required action.

able to make the rolls of cast iron and to secure to them steel dies, as in other rollingnail and spike machines, and then the rolls should be m'ade wide enough for strength, and the dies may be made narrow enough for convenient operation.

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

The two pairs of segmental rolls, I, I, and N, N', combined arranged, and operating, substantially as described so that the first pair bring the nail or spike, nearly or quite to the desired form, and the second may complete it, and by their reversed position finish off the finned, feathered or ragged corners, which were formed by the junction of the former rolls, as herein set forth.
