JOSEPH OVEN, OF DUNELLEN, NEV JERSEY.

AXLE-STRAIGHTENER.

SPECIFICATION forming part of Letters Patent No. 328,137, dated October 13, 1885.

Application filed June 12, 1885.

To all whom it may concern: v

Be it known that I, Josnrn OWEN, a citizen of the United States, residing at Dunellen, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvementsin Axle-Straighteners, oi' which the following is a specification.

My invention relates to improvements in devices for bending or straightening axles; and the purpose of my improvement is to provide a machine which is simple in construction and capable of being readily adjusted to axles without their being removed from the carriage, and is arranged for setting or straightening any portion of the axle, in whatever direction it may be bent.

'In the accompanying drawings,which serve to illustrate my invention, Figure l is a side elevation of my improved device, shown applied to an axle. Fig. 2 is a top view of the arm of the same. Fig. 3 is a cross-section taken on line x of Fig. 2, and Fig. 4 is a side view of the supporting-block.

Let a in general represent a supporting block or saddle provided with a suitable recess, b, for receiving the bed-iron of the axle c, which lits into it, as shown in Fig. Ll.V The entire inner surface of the recess is cushioned, preferably with leather, to prevent the marring of the axle or the rubbing on? of the paint of the wood-work. The cushion d extends over the exposed upper edge of the saddle, and is secured by a screw, e, io its outer surface, thus preventing any danger of rubbing the wood-work in the operation of inserting or removing the axle. A similar tapering recess, e', is provided in the top, bottom, and side portions, for receiving a tapered pin on the end of the detachable arm f, in which arm are mounted the pressure and lifting screwbolts, by which means the arm may be changed from one to the other side ofthe block, according to the direction in which the power should be applied. rlhe rear part of the arm f is provided with an aperture, through which the axle passes, and its inner wall is cut away to form a shoulder at the point h, which bears against the shoulder t' on the axle. j is a screwbolt adapted to give a downward pressure, and k is a similar bolt arranged to draw upward. The end of the axle is supported in Serial No. 168,543. (No model.)

the eye h, formed in the bolt 7c. The bolts j and 7c are arranged to have a lateral movement on the arm f, so that they are readily adjusted at any point over the axle where power is required. 'Ihe upper portion of the arm f is provided with a slot, Z, extending nearly from end to end, and movable blocks m and m', carrying the screw-threaded bolts j and 7c, are arranged to traverse to and fro in this slot. The carrier m has a screw-threaded aperture for receiving the screw-boltj. Lugsnl n are provided on its upper portion, which rest on the edge ofthe arm, and side flanges, a', on its bottom part are made to bear against a shoulder, b', formed within the slot, by which the carrier is held in position. The screw-bolt j, which is designed for giving a downward pressure on the axle when in the position shown iu Fig. l, has a square head, c', and is secured at its lower end by means of a pin, d', to a swivelblock, o, which has its under surface made concave to adapt it to fit over the axle, as shown at p.

The carrier m is provided with a smooth hole, d", through which the screw-bolt passes, and in which it has a free rotary movement. Side iianges, q, on the top edge of the carrier prevent it from slipping through the slot.

The screw-bolt 7c serves as a lifting-screw for straightening out a downward bend in the axle. h is an eye formed on the lower end of the bolt for receiving the axle-arm. a' is a screw-nut working on the bolt.

The arm j' is detachably connected to the supporting-block a by means of the pin Q', itting int-o the socket c in the block. Instead of the pin, however, I may use a screw passing through a screw-threaded aperture in the end of the arm, when by turning the screw until its end fits up tightly in the socket an accurate connection is effected.

As both screw-bolts are movable, it follows that the power desired may be applied at any the axle is drawn up to a horizontal position.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. In a device for straightening axles, the combination of a supporting-block, a bent arm detachably secured to said block provided with a longitudinal slotted portion, and adj ustable movable screw-bolts arr. nged Within said slot7 as and for the purpose set forth.

2. The combination of a supporting-block provided With a tapering recess in three of its sides with a bent arm provided with a conical plug for attachment to said block, and having a shoulder portion adapted to bear
