JULIUS B. SAVAGE, OF. SOUTHINGTON, CONNECTICUT.

NUT-MACHINE.

Specification forming part of Letters Patent No. 22,310, dated December 14, 1858; Reissued July 21, 1868, No. 3,050.

To all whom it may concern:

Be it known that I, JULIUS B. SAVAGE, of Southington, in the county of Hartford and State of Connecticut, have invented a new' and Improved Machine for Making Nuts; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a front elevation of my invention. Fig. 2, is a transverse vertical section of ditto, taken in the line 50, m, Fig. 1. Fig. 3, is a transverse vertical section of ditto, taken in the line 3 y, Fig. 4. Fig. is a horizontal section of ditto, taken in the line .2, .2 Fig. 1.

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

This invention consists in the employment or use of a cutting device, dies, punch and a series of adjusters and conveyers arranged substantially as hereinafter fully shown and described, whereby the blanks are out 01f from the bar properly compressed or formed and punched, ready for the tap,

' the several parts working automatically.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a bed piece which is properly supported at a suitable height and B, B, B, are three uprights attached to the bed piece and each having a guide plate O, attached, the guide plates having a sliding bar D, fitted in them. In one bar D, a cutter E, is fitted. To another a die F, having a flat or smooth horizontal face is attached and a punch G, is attached to the other. The upper ends of the bars D, are each attached to one end of levers H, the fulcra of which are in the upper ends of the uprights B, and the opposite ends of the levers are attached to connecting rods I, the lower ends of which are secured to eccentrics J on a driving shaft K. On the bed piece A, a horizontal die L, is placed. This die is simply a flat rectangular metal bar having a smooth face, the die being a trifle thicker than the nuts to be made and a trifle wider than double the width of the nuts. The die L, is operated from the shaft K. by means of a tappet a, on said shaft which tappet acts against a toggle bar or plate Z),

a spring 0, attached to the under side of the dieL, giving the return motion to the die.

M, is a stationary die plate attached to the bed piece A, in line with the die L.

N, is a stationary block attached to the bed piece in line with the cutter E.

O, is a shaft which is placed at one end of the bed piece and is rotated from the shaft K, by bevel gearing d, (Z, as shown clearly in Fig. 4:.

On the shaft O, a tappet e, is placed, and this tappet actuates a sliding plate P, the inner end of which is notched and forms a jaw, the plate P, being in line with a stationary plate or jaw Q, on the bed piece. A spring f, gives the return movement to the plate P. The two jaws P, Q, are beneath the punch Gr.

To one end of the shaft O, a crank pulley R, is attached and S, is a connecting rod one end of which is secured to the pulley R, and the opposite end secured to a slide bar T, which is fitted in proper guides attached to the front edge of the bed piece A.

To the bar T, two uprights g, g, are attached said uprights forming the bearings for a rod U, which has an arm V, attached. The lower end of the arm V, acts against a spring guide 72, which is attached to a plate 2', secured to the lower part of the bed piece. To the rod U, a series of feeding and adjusting arms j, is, Z, 121, n, are attached. The arm j, is a conveyer and adjuster both, the arm 7c, is a conveyer only, the arm Z, is a conveyer and adjuster, the arms on, n, are conveyers. To the outer end of the bar T, a short bar 0, is attached at right angles, and to the outer end of the bar 0, a short bar IV, is attached parallel with the bar T, the bar IV, being in line with the cutter X, is a stop which is attached to the bed piece A, directly back of the cutter E.

The operation is as follows :Power is applied to the shaft K, in any proper way and the bar Y, from which the nuts are formed is of a width corresponding to the desired width of the nuts. One end of this bar is heated and the heated end is passed by the operator underneath the cutter E, and against the stop X. The cutter E, descends and cuts off a blank which is square or has its sides of equal length, the cutter being operated by the lever I-I, rod I, and cam J, which are connected to it. hen

the blank is cut off the bar WV, moves inward and throws the blank within reach of the conveyer j, which, as the bar V, moves back or outward, passes over the blank and catches behind it. The bar it will be understood is attached to the bar T, and consequently moves with it, and all of the conveyer-s and adjusters y, 70, Z, m, n, being attached to the rod U, move also simultaneously with the bar V, as all are attached to the bar T. The conveyer j, in common with the others is elevated so as to pass over the blank as it moves toward. it, by the arm V, and spring guide 71,- the lower end of the arm bearing against the spring or elastic guide in consequence of a spring a acting against it, the conveyer and adjuster j, being depressed while moving in the direction indicated by arrow 1. The conveyer j, carries the blank in front of the die plate M, and the die plate L, then advances and compresses and smooths two opposite edges of the blank while the conveyer j, returns for a succeeding blank cut off from the bar by the cutter E. As the die plate L, recedes from the stationary plate M, the conveyer j, again moves inward with a succeeding blank, and a rod 6*, attached to the end of the conveyer j, turns the blank previously cut off so that as the die plate L, again moves toward the plate M, the two opposite sides of the nut will be compressed and smoothed. The conveyer 7:, then moves the blank along a certain distance in the same direction as before and the conveyer At this moment the jaw P, is actuated by the tappet c, and said jaw compresses the blank between itself and the jaw Q, while the punch Gr, descends through the center of the blank the jaws P, Q, centering the blank.

It will be understood that the blanks follow each other successively and several blanks may be cut from the bar Y, before being reheated.

It will; be seen that the several parts work automatically and but little attention or manipulation is required the bar Y, only being required to be properly presented to the cutter E.

Having thus described my invention what I claim as new and desire to secure by Letters Patent,- is,

The employment or use of the cutter E, dies L, M, F, and punch G, in connection with the conveyers and adjusters j, 70, Z, m, n, and the aws- P, Q, or their equivalents, the whole being arranged and combined to operate as and for the purpose set forth.
