TO ALL WHOM IT MAY CONCEHN:

Be it known that we, A. B. CANDEE, of Hamden, in the county-of New Hav'cn, and L.,S. TAYLOR, ot Southington, in the county of Hartford, and State of Connecticut, have invented a new Improvement in Machine for Making Axle-Nuts; and we do hereby declare the following, when taken in connection 'with the accompanying drawings, and the letters of reference marked thereon, t'o be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification, and represent, in-

Figure 1,V atop view,

Figures 2, 3, 4, and 5, detached views to illustrate the operation,

Figure 6, transverse section through the dies, and'in Figures 7 'and 8, perspective views of axle-nuts, such as are manufactured by this machine.

This invention isdesigned for the manufacture of the nuts which are used upon the outer end of carriageaxles, for the purpose of securing the wheel thereon, and the invention consists in the arrangement of a pair of dies which receive and cut eti' thel blanlr from the'bar of heated metal, and transfer the. said blank toa position opposite the requisite punches, and by the operation of which said punches thenut is formed in the same die which'transiers the blank.

To enable others to construct and use our improvement, we will-proceed to describe the same as illustrated in the accompanying drawings.

A is the bedplate, supporting, in bearings B B and C C, two shai'ts D and at right angles to each other, and the two geared together, so as to-revolve at equal, velocities.

F is one part of a die, operated by a cam, G, on the shaft D.

I H is t-he otherpart ofthe same die, operated by acum, I', on the shaft E through a rod, J, Aworking against the outer end of the die H. I

The die is formed or attached to the inner endof whatI are termed dies F and H, and are arranged so that when in the position as seen in iig. 1, the heated bar is placed before the die F through a block, K; then, as the machine is in operation, the die H moves upto andgrasps the rod between the two dies F and H g then the'said two dies advance together to the position in iig. 3, cutting oii` the blank from the bar as it bearsaganst the openingthrough the block K. Having been thus cutand transferred to this point, there is arranged, at right angles to the said two dies, apunch, L, fixed to a slide,'M, operated'by a cam, N, the said punch L being constructed so as to give to the inner end of the nut the proper form, as seen in iig.` 7 or 8; and the said punch, moved forward iuto'dies F and H, forces the metal intothe said dies to'form the exterior of the nut; then a punch, a, within the punch L, is forced forward by a cam, P, and pierces the nut; then, the punches retreating, the dies open, and discharge the completed nut, receive a new blank, and operate as before described.

The cut-o` block K is arranged so as to be removed, as occasion may require, for repairs, or when it has become wornrby the cutting od" ofthe blanks against itsinner surface.

"Having thus fully described our invention, what we claim as new and useful, and desire to secure by Letters Patent, isil The cornbination'oil the cut-oliv block K, griping-dies F and H, die L, and punch a, all constructed, arranged,

and operating in the manner substantially as described.
