' IMPROVEMENTQIN MACHINES FOR uPsrrnue coLLARs ON VEHICLE-AXLES.

Specification forming part of Letters Patent No. 207,208, dated August .20, 1878 application filed July 10, 1878. g

ence being had to the accompanying draw-' ings, making part of this specification, in which- Figure 1 is a perspective view of a machine for the manufacture of axles with my inr-v provements applied. Fig. 2 is a plan View of the same, showing the die-holders closed. Fig. 3 is a vertical cross-section on the line as a; of Fig. 1. Fig. 4 is the same on the line yy of Fig. 1. I

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

My'invention relates to machinery for upsetting collars on vehicle-axles of any kind; and it consists in the combination of devices hereinafter explained and claimed.

In the drawings, A represents the framework sustaining the machine; B, the driving- .wheel for operating the machinery which drives the sliding hammer a through the medium of the adjustable pitman b. The dieholders 0 C are hinged to the frame A, and secure in position the compressing-die d and holding-die (1. Each of these dies is divided longitudinally into two halves, the upper half of each being secured in the hinged die-holders, and the lower half secured to the bed-plate E in the frame A. The holding-die d is rigidly fixed in position in the die-holder, while the compressing-die d has a longitudinal movement within the die-holder from and toward the holding-die, being forced more or less to the rear by the springs c e, and again carried forward by the sliding hammer a during the process of upsetting the collar on the axle.

()n the opposite side of the frame to the hinged die-holders is hinged the catch F, which slides over the die-holders and secures "exactly equal to the angle of the cam formed upon the face, whereby I secure an abutment at right angles to the line of the groove, whatever may be the position' of the revolving abutment.

By means of this cam.-faced abutment I am enabled to increase or diminish the length of the groove for holding the axle, and thus readily adapt my machine for axles of varying lengths.

In applying my machine to the upsetting of collars on axles, I first take the bar of iron and round a sufficient portion of one end to make the arm and collar of the axle of the exact size for the arm, which is fully inclosed in the sliding dies (1, the end resting against the interior of the'dies d, which forms the abutment for the arm end of the axle during the operation of forming the collar. The collar of the axle is made by compressing or upsetting the round portion between the sliding dies 11 and the fixed dies d.

The operation of my machine is as follows: The upper section of the die-holders and dies being thrown up, as shown in Fig. 1, the axle is introduced into the machine, the arm end lying on the compressing-die d, with the round overthe space between the two dies, and the opposite end resting against the abutment H, which is turned in position to accommodate the exact length of the axle-bar. The hinged die-holders, with the holding and.compressing dies, are then brought down in position and secured by the catch F. The holdingdies d close around the bed of the axle-blank, holding it firmly in position, while the hammer it drives forward the compressing-die d and upsets the collar of the axle in the space between the dies. When the die-holders are raised from the catch and thrown up and the sliding hammer withdrawn; the springs e 0 2a In combination with the holding and throw back the compressing-die, and the axle compressing dies 01 d, the cam-faced abutment is ready to be lifted from the machine H, substantially-as and for the purpose set Having thus described my invention, what forth. a I claim as new, and desire to secure by Letters j Patent, is' v 1. The holding and compressingdies d d, with the hinged die-holders G G, catch F, Witnesses: sliding hammer a, and cam-faced abutment PAUL K. LEONHART, H, constructed to operate substantially as and JOHN EWING SPEER. for the purpose set forth. I
