OF ALBANY,

YORK.

MACHINERY FOR HEADING BOLTS, 85o.

Specicaton of Letters Patent No.

T aZZ 'whom it '1n/ay conce/rn.'

Be it known that I, EDWARD PAYE, of the city and county of Albany, in the State of New York, have invented a new and useful Machine for Heading Bolts, Spikes, Rivets, &c.; and I do hereby declare that the same is described and represented in the following' specification and drawings The nature of my invention consists in a permanentrpivot with a hole in the center to which a die is fitted against which die the end of the rod to be headed is driven while it is held in a pair of jaws closed by a cam, and connected to a sliding hammer traversing upon rods or ways pressed back by cams and forced forward by springs so as to upset the end of the rod held in the jaws by striking it against the die in the pivot at the same time the head is squared by four sliding hammers which traverse in scores across the end of the pivot, being operated by grooved cams in a collar which is tted to turn on the pivot which collar also carries the cams which press back the sliding hammers.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation, referring to the accompanying drawings in 301 which the same letters indicate like parts in each of the figures.

Figure 1, is a plan or top view. Fig. 2 is a sectional elevation through the line e, s, of Fig. 1. Fig. 3, is an elevat-ion of the front end-some of the parts are represented as broken 0E to show others.

A A is a strong frame made in the form represented supported by the legs B B. The head stock C is fastened to the frame by the bolts b b and is supported by the projections a a. The head-stock C has the projection or pivot D cast with it, with a hole in the center for the die E, which is fitted to it and secured by the nut 0. The pivot D has two scores across the end at right angles to each other one of which is seen at F.

In each of these scores there is a sliding hammer Gr-(see a side elevation Fig. 4)

which hammers are forced forward, that is the two which stand opposite to each other, at the same time by two cams in the collar H, which is fitted to turn on the pivot D,

one of which cams is represented at I. The

sliding hammers Gr are drawn back by the pivot eZ which extends into the groove J in the collar H. The face plate K fastened to 9,506, dated December 28, 1852.

the pivot D by the screws e e holds the slid lng hammers Gr in the scores F; this face plate also ts a rabbet in the collar H and holds it on the pivot D.

The collar I'I has the gear L on its back end which gear is turned and also the collar by the gear M on the shaft N to which shaft a gear or pulleys may be applied so as to communicate the power requisite to operate the machine. The shaft N turns in a box on the top of the head-stock C and in a box on the stand O which stand is fastened to the frame A; and a fly wheel P is fastened to the shaft N to equalize the motion. The stand Q is fastened to the frame ik and supports the ends of the rods R R the opposite ends being supported by the headstock C as represented. The traversing halnmer S is itted to slide on the rods R R and has the stud T fastened to it with a friction vwheel f in the end against which the cams U U act and press the hammer S back it being forced forward by the spiral springs V V on the rods g g which rods are fastened into the end of the fralne A; the spiral springs V T act against the end of the frame AA and the cross-head VV fastened upon the traverse rod X by the pin L, which rod X extends through the hamlner S which is fastened to it by the screw i, and through the arm Y fastened to it by the screw 7' and pin 71;, and the end of the frame fr in which it traverses to operate the hammer S which hammer has a cavity in the top to which the jaws Z Z are fitted, which jaws have a score in each of them to fit the rod of the bolt m; the jaw Z is pressed back to the position represented by dotted lines by the spring 711 placed between the on the pin p also represented by dotted lines in Fig. 1. The jaw Z is forced up to the jaw Z by the cam g on the end of the lever 7 which lever vibrates upon the screw s in a cavity fitted for it in the hammer S. rIhe rod of the bolt m is stopped by the arm Y so as to form the bolt of the desired length the arIn being adjusted to the proper position on the rod X for that purpose. The gage or stopt traverses in the stand u is fastened to the frame A. It is raised by the spiral spring QJ so as to stop the hammer S and is drawn down by the lever w which may be depressed by the foot whenever it is desirable to' release the hammer S to head a bolt.

The machine having been constructed and completed as above described, and some
