NATES PATENT OFFICE.
EDWARD .KA-YLon, oF rrrrsnae, PENNSYLVANIA.
`IMPRQVEM ENT IN lsoLT-lvlAcl-urlas.
Specication forming part of Letters Patent No. 49,532, dated August 22, i365.
To all whom fit may concern:
Beit known that I, EDWARD KAYLoR, of the city ot' Pittsburg, in the county ot' Allegheny and State ot' Pennsylvania, have invented a new and useful Improvement in Bolt- Machines; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the annexed drawing, forming part of this specification, which. is a perspective representation ot' my improved machine.
To enable others skilled in the art to construct and use my improved bo1t-machine,I will proceed to describe its construction and operation.
In thedrawing, a is a strong rectangular frame supporting the machinery. b b are two cross-pieces, which serve as supports and bearings for the header-arm c and the wedge-arm d, by which the die e is advanced to hold and shape the shank ot the bolt in the cavity t',
i formed by the closing of the dies e and e. i At the rear end of the machine is a transi verse horizontal cam-sliat't,f, from the revolution of which motion is communicated to all parts of the machine. On this camshaftfare. three eccentric-cams, g g g2, on the periphery of each of which rests a roller, li h 11,", one of which is placed in a fork at the rear end ofthe wedge-arm d, the header-shaft c, and cutterlever 7c, respectively. As represented in the drawing, each of these rollers h h' h touches its cam at the point ot' its circumference nearest to the center otl the shaft, so that the die e is open, the header l is drawn back, and the cutter m is raised, and so that any further motion of the main shaftfand its attached cams i gg/g iwould cause the die c to move toward the stationary die c, the header l to advance, and the movable cutter m to descend toward the stationary cutter m.
l The die c slidesin bearings in the frame with "al horizontal,` movement parallel to the tace of `the stationary die e anu to the axis of the header l, this motion being effected by means tf the wedge-shaped head d ot' the shaft d, i which passes between a pair of Jrriction-rollers, n, one attached to the frame of the machine d the other to the side ot' the movable die e. y e returnmotion ot' the die e, when the wedge 1d s Withdrawn, is caused by the spring s and odg. The axis ot the header lis in the same horizontal line as the center of the cavity t' in the stationary die e, and the motion ofthe header is in that axial line.
The cutter-lever k has its l'ulcrum iu the standard p, and near the forward end of the leveris the cutter m, which depends perpendicularly from the lever la, on which it slides by means of the loop t, and on which it is set in the required position by the set-screw u. The lower cutter, m', rises perpendicularly from a slide, c, which works in grooves in the frame ofthe machine, so that it can be slid in or out toward or from the front end of the die e'. It is set in any required position by a screw, o, or by a key hidden from view in the drawing. The cutters m 'm' are directly in front of the cavity ot' the dies e e' when closed, and the top of the stationary cutter is in front of the axial line, or a little below it, so that by the descent of the upper cutter, m, which is set so as to graze the lower cutter in passing it, the rod from which the bolts are made is severed as by a pair of shears. j usted to the required distance from the end of the dies to make the bolt of any desired length without alteration of thedies.
As the cams gig cause the shafts d andcto advance to close the diesand press the header l against the rear end ot' the dies withoutdrawing` them back again, the return motion is effected by the springs s s, and the roller h" on the lever 7c is kept down on the circumference of its cam g" by the spring w, or by a weight. l
The operation ot' my machine is as follows:
The cutters m m are adjusted at a distance from the rear end of the dies e e equal to the required length of the bolt when finished. The rod from which the bolt is to be made, being rst heated, is inserted into the machine over cavity in the dies made to shape the head',and i and at the same time the upper cutter, m,de
The cutters m m are ad` What I claim as my invention, and desire to secure by Letters Patent, is
The use, in bolt-machines, ofthe detached cutters m m', placed in frontot' and susceptible of adjustment to and from the face ot' the griping-dies, in combination with the screw o and slide e, for adjusting the lower cutter, and the l lever k and loop t, for operating and adjusting the upper cutter, substantially as described, for the purposeof cuttingoff the blank to make 'any desired length of bolt Without requiring any change ofthe dies.
In testimony whereof I, the said EDWARD .y
KAYLOR, have hereunto set my hand.
