SPECIFICATION forming part of Letters Patent No. 757,345, dated April l2, 1904.

Application filed October 30, 1903. SerialNo. 179,213. `(Nt model.)

To @ZZ whom, it may concern: h

Be it known that I, WILLIAM G. PRICE, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Brake-Rigging; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.-

This invention'relates to improvements in car-trucks, and particularly to brake-rigging therefor.

The object in view is the supporting and disposing of a brake-rigging in such manner as to minimize or totally overcome vibrations due to the application of brake-shoes.

A further object is the support of a brakerigging in such manner as to obviate the necessity for the interposition of springs for carrying the same, whereby the brake-shoes may be maintained at a given fixed height.

A further object is attained by the mounting of the present improved rigging in such manner as to enable the removal of the truckframe bodily without interfering with or deranging said rigging. A

With these and further objects in view the invention consists in combination, with a cartruck frame and wheels,of equalizer-bars connecting the axles of said wheels and a brakerigging carried by said bars.

It still further consists in certain other novel constructions, combinations, and arrangelments of parts, as will be hereinafter fully described and claimed. -I v In the accompanying drawings,F1gure l represents a top plan view of a portion of cartruck provided with a brake-rigging embodying the features of the present invention. Fig. 2 represents a view in side elevation of the same. Fig. 3 represents a vertical transverse section taken on the plane of line 3 8 of Fig.

2. Fig. 4 represents an enlarged fragmentary horizontal section taken on the line 4 4 of Fig. 2.` Y

The bolster of the common types of cartrucks is usually cushioned in such manner as to absorb as much of the vibration of the truck as possible to prevent jarring and shakplane of ingiof the car carried thereby, but, as is well known, the application of the brakes usually occasions sufficient vibrations to be felt in the l car despite the interposed cushions, and by thepresent invention I contemplate' obviating the vibrating of the frame of a car-truck by the supporting of the brake-rigging independently thereof, as will be seen from the accompanying drawings, in which- 1 indicates the frame of a car-truck, preferably of the type illustrated in applications for patents previously filed by me. Wheels 2 2 carry said frame by means of their axles 3 3,

i journal-boxes 4, and equalizer-bars 5, connecting said boxes and provided with cushioningframes 6 6, upon which the said frame l rests, each set of boxes 4 at one side of the frame 'being provided with an interposed equalizerbar 5, consisting of parallel plates spaced apart at each end by a lug 7, carried by the respective boxes 4, said plates being secured together by bolt 5 8, extending therethrough and through the lugs 7 The ends of each bar 5 are bent and rest upon the upper surface of the boxes 4, the plates constituting each of said bars having their ends spaced apart a distance suiiicient for permitting verticalk movement of the respective side frame making up the general frame 1 between the said plates. Arranged transversely of and secured to the frame are transoms 9 9, between which is supported a car-body-supporting bolster 10 upon cu'sh ioning-springs 11, supported by said transoms. As the opposite sides of the frame i l and the surrounding parts are exact duplicates, I have illustrated but one side, and the tion of each of lugs 13 surrounding bolt 14 is slightly narrower than lthe space between the plates forming bar 5, and a bracket 15 is interposed between the lug and the outer of said plates, said bracket extending in an inclined plane upwardly and inwardly and being formed at its upper end with a hook 16. A similar bracket 17 surrounds the inner end of bolt 14C, with Yits lower end resting against the inside face of the inner plate of bar 5, and said bracket extends upwardly and is formedwith a hook 18, fitting snugly within the hook 16, a link 19 being pivotally supported within said hooks by a bolt 20, extending therethrough. The lower end of each link 19 supports a brakeshoe 21 by means of its web 22, pivotally connected to said link by a bolt 23, passed through Y the lower end of said link and web. A jaw projects from each of the webs 22 and consists of links 24 24. Extending between and pivotally connected to each set of links 211 is an operating-lever 25, the lower ends of each set of operating-levers 25 on one side of the frame beingv pivotally connected together by a suitable turnbuckle 26, whereby actuation of one lever is designed to actuate the other in an opposite sense. One of the levers 25 has its upper end left free to contact with one of the transoms 9, and to the upper end of the other of said levers is connected a draw-bar 26, said bar at its forward end pivotally engaging one end of an evener-bar 27, any suitable draft device 28 being applied to said evener for actuating the same. A rod 29 connects the end of evener 27, to the frame 1 by bolt 30, a spring 31 being interposed in the length of said rod for normally retaining the evener-bar in position for supporting the brake-shoes out of contact with the wheels 2.

Each brake-shoe 21 is held against lateral play in one direction by means of the flange of the given wheel 2 and is retained against lateral movement in the opposite direction by the flat portion 32 of bracket 33, carried by the 'inner end of bolt 14:. rlhe equalizer-bars 5 on the opposite sides of the frame are bound together and held against lateral movement independently of -each other by means of tie-rods 34 34C. A bracket 35 is secured to each bar 5 near each end of each turnbuckle 26, and each of said brackets has its lower end extended beneath and curved about the turnbuckle for receiving and supporting the same in case of accident to the brackets 15 and 17 or other supporting parts.

In operation the evener-bar 27 is drawn forwardly, whereby the upper end of thelever 25, to which the bar 26 is attached, is moved forwardly, applying its respective shoe to the wheel 2, and swinging on the bolt connecting the same, with links 25 as a fulcrum, moves the turnbuckle 26 and the lower end of the opposite lever 25 rearwardly for applying the shoe actuated by the last-mentioned ever.`

Aside from the advantage gained by the positioning of the brake-rigging in the preventing of vibration I accomplish a further obviously desirable advantage in the omissionof the common brake-beam. By the use of the evener-bar the brake-shoes may allbe applied simultaneously without the necessity of a connecting brake-beam between the same.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a frame, of a cartruck and an equalizer-bar, comprising a plurality of parallel members separately formed, of a brake-shoe hung from a laterally-projecting bracket supported by said bar.
