APPLICATION TILED AUG. 23, 1905.

UNITED STATES PATENT oFFIcE.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed August 23, 1905. Serial No. 275,387.

To all whom it may concern:

Be it known that I, WILLIAM F. KIEsEL, Jr. a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented a new and Improved Brake-Rigging, of which the following is a specification.

This invention relates to improvements in brake-riggings for railway-car trucks, and more particularly to the brake-rigging adapted for use in connection with the four-wheel car-truck described in my application for Letters Patent of the United States, Serial No. 269,144, filed July 11, 1905.

The objects of my invention are to provide a simplified arrangement of the brake-rigging comprising independent duplex brakes for each side of the truck; to dispense with brakebeams, the brake-heads being suspended directly from hanger-supports attached to the wheel-pieces; to locate the operating levers and links above and clear of the bolster, and to operate the two independent riggings through the medium of an equalizer-bar coupled to the brake-operating system. 1 attain these objects by arranging and assembling the several parts of the brake-rigging and applying them to my improved truck in the manner illustrated in the accompanying drawings, in which Figure 1 represents a side elevation of the brake-rigging at one side of the truck with truck shown sectioned on a longitudinal line through the center plate; Fig. 2, a plan view of the complete brake-rigging, showing portions of the wheel-pieces and the manner of attaching the riggings thereto; Fig. 3, a half end view of the rigging, showing also one of the wheel-pieces in vertical transverse section; and Fig. 4, a detail plan view of one of the brake-lever-connecting bars.

Like numerals indicate like parts in the several views.

The truck comprises a center plate 1, supported upon a transverse bolster and springbeam 2, hung from the wheel-pieces 3, as described in my aforesaid application. At the v inside of the vertical members of each of the wheel-pieces is riveted a hanger-bearing 4, which consists of a flanged casting having a projecting body portion, at each end of which are formed transverse upwardly-inclined lips 7,in which are inserted the horizontal members of the U-shaped shackles 8, to the free ends of which are coupled the brake-heads 9. The hanger-shackles are held in place between the lips 7 by means of blocks which fill the openings between lips and are secured in place by bolts passing therethrough. The brake-heads are each coupled to the lower end of the vertical levers 10, which rise above the'bolster and are coupled together at their fulcrum-points by the connecting-bar 11, which passes across above the bolster. This connecting-bar is double-sided, with a web adjoining the sides at the bottom between ends, the cross-section of the bar being of substantially U shape. The forked ends of the connecting-bar embrace the sides of the levers 10 to maintain them in vertical alinement and provide bearings for the fulcrum-pins at each side of the levers.

One of the levers on each side of the truck is coupled at its free end by a link 12 to the Vertical lug 5, which projects upwardly from the hanger-bar 4: in line with the lever pairs 10. The other lever 10 of each pair is coupled at its free end by a link 18 to the equalizer-bar 14, which passes transversely across the truck above the center plate, said equaliZer-bar being coupled at its center, by means of a link at 15, to the brake-operating system.

At the center of the hanger-bearings there is provided a rectangular guideway 6 to receive one of the springfollowers forming part of the side-motion spring attachment between the bolster and wheel-pieces, as described in my aforesaid application.

When operating the brakes, as will be seen from an inspection of Fig. 1, a pull to the left on the equalizer-bar will throw the lower end of the right-hand levers to the right, thereby setting the brakes on the right-hand wheels, and the left-hand levers will be forced over to the left by the action of the right-hand le. vers on the connecting-bar 11, thereby setting the brakes against the left-hand wheels. By this arrangement of the separate brake-riggings on each side of the truck I dispense with all bottom hamper, leaving a free and clear space below the car axles and bolster, all the operating parts of the brake-riggings being located above the bolster. Each brake acts independently of its fellows, the brakelevers constituting, in elfect, equalizer-bars, whereby the braking force will be applied in equal degree upon each one of the wheels.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a car-truck, the combination of independent brake-riggings on each side of the truck supported from the wheel-pieces, an

equalizer-bar passing across the truck at a point adjacent to and above the center plate or pivot-point of the truck, operating-levers in both riggings coupled to said equalizer-bar, and a connection between said equalizer and the brake-operating system.

2. In a four-wheel truck, a brake-rigging comprising brake-heads suspended at points opposite each of the four wheels, vertical levers coupled to the brake-heads, bars passing over the top of the truck-bolster and coupling together the pairs of levers on each side of the truck, links coupling the free end of one lever on each side to fixed points on the truck, and connections between the free ends of the other two levers and the brake-operating system.

3. In a four-wheel truck, the combination, with the wheel-pieces, of hanger-bearings attached to the inside of each wheel-piece, hangers suspended therefrom opposite each of the four wheels, brake-heads carried by the hangers,vertical levers coupled to the brake-heads, bars coupling together the pairs of levers on each side of the truck, links coupling the free end of a lever on each side to the wheel-pieces, a transverse equalizer-bar coupled to the other two levers and having a central pivot-point positioned above the center plate of the truck, and a connection between said central pivotpoint of the equalizer and the brake-operating system.

4. The herein described hanger bearing comprising a flanged casting adapted to be attached to a wheel-piece, said casting being provided with transverse upwardly-inclined lips at each end to receive brake-head hangers, and having a vertical lug to receive the-eye of a lever-link.

5. In a brake-rigging, a pair of vertical levers coupled to longitudinally opposite brakeheads, in combination with a connecting-bar passing over the top of the truck-bolster and uniting the two levers at their fulcrum-points, one of said levers being coupled at its free end to a fixed point and the other lever being coupled at its free end to the brake-operating systern.

6. The channeled two-sided connecting-bar having forked ends, substantially as and for the purpose herein described.

7. The combination, with a truck comprising wheel-pieces and a transverse bolster, of a brake-rigging composed of brake-heads suspended from the wheel-pieces at each side of the bolster, brake-levers rising therefrom, and operating-links and connections located above the bolster.

In testimony whereof I have aflixed my signature in presence of two witnesses.
