IMPROVEMENT IN BOLT-MAKING MACHINES.
Specication forming part of Letters Patent No. 128,853, dated July 9, 1872.
i Specication describing an Improved Mah chine for Heading Bolts and Screws, invented by AUGUsTrNE CHARBoNo, of the city and county of Worcester and State of Massachusetts.
This invention is designed chiey for heading the blanks of screws for screw-wrenches but it is applicable to heading other screws and bolts. It consists in a novel arrangement oi' and .means of operating a gauge by which the length of the screw or bolt is gan ged.
In the accompanying drawing, Figure 1 is Fig. 2 is a section of the same atthe dotted line x w-in Fig. 1, and Fig. 3 is a similar section taken at the dotted line y y in that gure. Fig. 4 is a view of the blank of a screw forv screwwrenches.
Similar letters of reference indicate corresponding parts in all three figures.
A is the bed of the machine, of square form and having formed on two sides, at right angles to each other, boxes a a', of which one,a, contains the bearings for the driving-shaft B, and the other, a, the bearings for a shaft, C. The middle portion of the driving-shaft is formed to constitute a crank, b, and the corresponding portion of the other shaft, G, has a cam, c, provided on it; said shafts are geared by miter-wheels on their adjacent ends. In that portion of thebed opposite the crank ofthe driving-shaft there is a parallel opening constituting a way, e, which is -arranged opposite 'the shaft. F is a slide, which carries the headingplunger Gr and moves at right angles to the shaft B. Motion is transmitted to it by a vibrating arm, D, and block E. The former is concavely rounded to fit the crank b at one end, and at the other it is rounded to fit the concave end of the block E. The headingplunger has a recess or cavity, s, in its end for the purpose of forming the pivot of the screw. The cam c, on the shaft C, operates the movable jaw of the forming and holding dies, and for this purpose an arc of its greatest radius is concentric with the shaft G to hold said movable die stationary during the operation of the heading-plunger. Opposite the cam there is in the bed a parallel opening constituting a way, f, in which the movable die-block H slides. It has interposed between it and the cam abl0ck,l, and,when necessary, one or more packin g-pieces, J. The stationary die-block K is arranged in the end of the way f in such position that the line of its face is opposite the center of the heading-plunger G. The faces of this and the movable`die-block are similar, except that one is provided with the knife or cutter r and the other with a recess to receive said cutter. In each there is a holding portion, fn, to grip and hold the rod or blank to be headed, and an enlarged portion, o, which forms the heading-die and receives the plunger G. On the top of the stationary die-block thereis secured a gauge, M, consisting of a spring, which is secured at one end so as to be capable of adjustment, and has its other end turned at nearly a right angle, as shown at t, to form a stop, which projects over the end of the stationary die-block and gauges the length of the screw or bolt blank to be formed. A tappet, N, secured adjustably on the sliding die-block pushes the gauge aside and moves it out of the way, of the headingplunger as said block moves toward the other. L L are two cap-plates, which coverthe ways e and fand secure the blocks within them. Each is provided with a slot; through one a pin, g, on the sliding die=block projects, and a pin, t', on the heading-plunger block projects through the other. A spring, P, provided with two arms, is arranged on the bed, so that its arms, bearing against the said projecting-pins g and i, force the slide F and block H back when not thrown forward by the crank b and cam c.
A heated bar of iron of the size of the body of the intended screw-blank is fed through a guide and between the dies till it ends touches the gauge M. The movable die then slides forward and the cutter cuts off a piece of the required length, which is griped between the dies. It also throws back the gauge out of the way of the plunger, which then moves forward within the dies and upsets the ends Claim.
of the piece of rod eut off, and forms the head of the screw-blank or bolt, and the cavity s in The combination of the adjustable springthe end of said plunger forms the journal or gauge M and the adjustable stop N with the pivot of said screw, shown in Fig. 4. The stationary and movabledies, substantially as sliding die and the plunger then move back and for the purpose speeied.
