No. 452,135. v Patented May 12,1891.

UNITED STATES PATENT (J ICE.

CHARLES \V. HUNT, OF VEST NEl V BRIGHTON, NEXY YORK.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 452,135, dated May 12, 1891.

Application filed February 16, 1891. Serial No. 381,597. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES W. HUNT, a citizen of the United States, residing at Vest New Brighton, in the county of Richmond and State of New York, have invented an Improvement in Railway-Oar Trucks, of which the following is aspecification.

In railway-car trucks such as shown in my patent, N 0. 347,936, a single axle with a pair of Wheels upon it has been pivoted at thecentral part by a sleeve around the axle and a triangular frame hinged to the frame of the car. In this construction of car-trucks there is often considerable bending strain upon the king-bolt, especially so when the journalboxes are connected by links to the frame.

My present invent-i011 is intended to relieve the king-bolt from lateral or bending strain; and it consists in an arm extending out from the sleeve and bearing against guides upon the frame, so that the strength of the arm or bearer is availed of for maintaining the bearer and king-bolt in a vertical position and preventing'the bending-strain coming upon the king-bolt.

In the drawings, Figure l is a plan view representing the present improvement as applied to a pair of truck-wheels, and Fig. 2 is a vertical section at the line 00 a: of Fig. 1.

The wheels B are upon the axle O, and there is a cross-bearer or sleeveE between the two wheels and over the axle, and the truck or frame A may be of either wood or iron, and itmay be either between the wheels or outside of the same, and any suitable connection may be provided between the axle-boxes and the frame. The king-bolt 5 serves to connect the sleeve or bearer E to the car, and this king-bolt 51night pass into a cross-beam of the car itself 5 but I prefer to employ a triangular frame L, through which the kin g-bolt 5 passes, and the base of the triangular frame L is represented as connected by the crossshaft or hinges 4: to the car or truck frame. An arm G extends out laterally from the sleeve or cross-bearer E, and such arm passes in between two supports 6 and 7. Thesesupports 0 and 7 may be directly one above the other, or they may be one in front of the other. I have represented

such supports

6 and 7 as upon the triangular frame L, and

the arm G between such supports is free to be moved by and with the sleeve or bearer E, as such bearer E and the axle assume a more or less inclined position to the center of the all circumstances the pair of truck-wheels, 1

axle, and sleeve can swing upon the king-bolt 5 in either passing around a curve or in travcling upon a straight track, and the arm G between the

supports

6 and 7 relieves the king-bolt of any strain tending to bend such king-bolt, because the arm G holds the bearer E in its proper upright position, but at the same time allows for the turning of the parts upon the king-bolt.

In cases where springs are applied between the hanging links and the axle-boxes, it is preferable to make use of the triangular frameL and to provide the

supports

6 and 7 for the arm G upon such frame, because the parts are held in their proper relative position at the same time that a rising-and-falling motion of the car-body'or truck-frame upon the springs is allowed for. The flanges of the car-wheels B are on the outside, as shown, because with one pair of wheels and an axle swinging upon the king-bolt the outer flanges are found in practice the most reliable for giving the proper horizontal movement or swing to the axle in entering and leaving curves in the track.

I claim as my invention 1. The combination, with the car wheels and axle, of a bearer on the axle and between the wheels, a pivot connecting the bearer with the car body or frame, and an arm extending out from the bearer, and supports against which the arm is permitted to move horizontally and by which the bearer is retained in normal position, substantially as set forth.

2. The combination, with the car-frame and the pivoted frame, of an axle and pair of Wheels, a sleeve or bearer over the axle between the wheels, a king-bolt connecting the bearer and the frame, an arm extending out from the bearer, and supports upon the frame,

the arm, between which such arm is allowed a limited horizontal motion, substantially as Set forth.

Signed by me this 12th day of February, 1891.
