SPECIFICATION forming part of Letters Patent No. 751,491, dated February 9, 1904. Application filed January 20, 1903. Serial No. 139,729- (No model.)

To all whom it may concern..-

Be it known that I, WILLIAM D. FLORANCE, a citizen of the United States, residing at Dallas, in the county of Dallas and State'of Texas, have invented certain new and useful Improvements in Upsetting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention comprises a machine for repairing worn axles by upsetting the same in a die of larger size, so that the axle will be enlarged to fit the old box.

The object of the invention is to form a simple, cheap, and efiicient machine for this purpose.

In the accompanying drawings, Figure 1 is a perspective view of the machine with an axle in position to be upset. Fig. 2 is a top plan view of the machine. Fig. 3 is a plan view of a tool used to engage behind the collar of the axle. Fig. 4 is a perspective view of the die detached. Fig. 5 is an end view of the movable abutment, and Fig. 6 is a vertical crosssection showing the holder for the die.

Speaking generally, the machine comprises a movable receiver acting as an abutment to hold the axle, a die to receive the spindle thereof, and a plunger acting longitudinally against the end of the spindle to upset the same. The plunger and abutment are actuated by hand cam levers, as more fully hereinafter explained.

Referring specifically to the drawings, 6 indicates the bed-plate, with which is cast a stock or holder 7 to receive'the die 8. This die is made in one piece, and the shape and size of its bore are according to the result desired. It is held against endwise movement in the stock by shoulders 8, but can beremoved through'the open side of the stock when desired.

The movable abutment or holder for the axle is indicated at 9 and has a longitudinal recess, as at 9, on a line with the die and open at the side, as shown, to permit the entry of the axlespindle into the die. The abutment is slidable longitudinally to and from the die between undercut guides 10, formed on the bed-plate, and is moved by a cam-lever 11, which is pivoted on the bed-plate to swing horizontally, and its cam-face 11 works in a corresponding recess formed in the under side of the abutment-block. At 12, Fig. 1, is indicated an axle in position to be upset, and 13 indicates a forked-size tool which fits over the axle behind the collar thereof and sustains the thrust 1 on the spindle. Several of such tools may be supplied for use, of different sizes,'to accommodate axles of different sizes. For the same purpose dies of various sizes may be provided.

The upsetting plunger or tool is indicated at 14. This is headed to fit over the axlethreads and come against the shoulder at the outer. end of the spindle, so as not to mar the threads. The plunger works in the bore of a guide-piece 15, cast on the bed-plate, and is What I claim as new, and desire to secureby Letters Patent, is V p The combination with a bed, and a die-stock projecting upwardly therefrom and open at one side, of a perforated die in the stock having projecting shoulders bearing against the ends of the stock, a sliding abutment opposite one end of the die having a groove lengthwise thereof to receive the work, and a plunger opposite the other end of the die.

1n testimony whereof I afiix my signature in presence of two witnesses.-

WILLIAM '1). FLORANCE.
