.MACHINE FOR MAKING AXLES.

SPECIFICATION forming part of Letters Patent No. 524,092, dated August 7, 1894. Application filed July 6,1893. Serial No. 479.711. (N0 model.)

To all whom it mag concern:

Be it known that I, OAMILL'EMEROADER, of Braddock, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Axles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, which show a horizontal sectionalview of my improved machine.

My invention relates to the manufacture of axles, having enlarged portions or collars, and it consists in an improved machine employed in manufacturing such axles, all as herein} after more fully described and set forth in the claim.

In the drawings, 2, 2, indicate the formingdies, having registering matrices 3, which to- .gether compose the mold-cavity within which the axle is formed. 'These matrices extend the entire length of the dies, the mold-cavity being open at each end and having near the ends annular recesses 4, 4, to form collars upon the finished axle. At the ends of the mold-cavity are located the piercing plungers 5, 5, having rounded ends which are adapted to pierce the ends of the blank and force the metal laterally into the annular recesses of the matrix dies. The two sets of plungers are carried by hydraulic cylinders 6, supported in a framework 7, and the method which I employ in connection with this apparatus is as follows:

A heated blank, consisting of a bar of iron or steel, of proper length, and, if desired, re-

sired for the middle portions of the axle, being placed between the forming-dies, they are forced together, thus forming the intermediate portion of the axle and at the same time clamping the blank securely in place. The plungers are then forced inwardly, and plercing the ends of the blank, force the metal outwardly into the recesses of the mold-cavity,

In a machine for making axles, the oombiduced to or approximately to the shape denation with a pair of matrix dies for forming and clamping the axle blank, of two piercing dies at right angles to the matrix dies and arranged to enter the open ends thereof, and force the metal laterally to form the collars,

and mechanism for operating said dies; substantially as described.

In testimony whereof I have hereunto set my hand.

CAMIILLE MEROADER.
