v To all 'whom t may concern.'

Be it known that I, JEssE SEYMOUR VVATI-IEY, a citizen of the United States, and a resident of Butte, in the county of Silver Bow and State of Montana, have invented a new and Improved Brake-Rigging, of which the following is va full, clear, and exact description.

This invention relates particularly to brake rigging, and its object is to provide a cai` truck with a brake rigging, wherein the rods may pass above and below the motors, by virtue of a diagonally-disposed equalizing lever, to apply the brakes simultaneously to all of the wheels. These and further objects, together with the construction and combination of parts, will be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the views, and inA which- Figure 1 is a top plan view; Fig. 2 is a side view in elevation; and Fig. 3 is an end view in elevation.

Referring generally to the drawings, 1 indicates a plurality of car wheels which are connected in the usual manner in pairs by axles 2. These axles are provided at their outer ends with the usual journal boxes 3, which are adapted to support a car truck frame 4:.

For the purpose of carrying out the objects of the. invention, there are provided brake shoes 14, which are of such structure that they engage both sides of the flanges of the wheels, so as to prevent them from moving transversely and thus eliminating loose rattling. These brake shoes are further provided with ribs 15 on their back sides, whereby the shoes are strengthened and reinforced, so that they can be worn down quite thin; before being discarded, and further whereby suitable means for attaching the supporting and operating members for the shoes is afforded. Connected to these ribs, for the purpose of supporting the shoes, there are provided hangers 16, which are pivotally supported on the frame 4L in any suitable manner, but preferably so that when the braking force on the shoes is released, the shoes are automatically swung by gravity to a position out of contact with the wheels. Also connected to the ribs 15 are toggle arms 17, which are also pivotally connected together at a point 18, at which point a link 19, is also pivotally secured at one end. The opposite end of the link 19 is pivotally connected to a short arm 20 on thel brake shaft 21, which is rotatably supported on the frame 4t in any suitable manner. This brake shaft 21 is also provided with a long arm 22, whereby it may be operated. The opposite end of the long arm 22 is pivotally connected to a link 23, which in turn is pivotally'connected at its opposite end to a transverse lever 24. It will be noted by reference to Figs. 2 and 3 that this transversev lever 241 is diagonally disposed and is pivoted on an inclined pivot 25 intermediate its ends, so that the link 23 may pass beneath the motor, and a link 26, connected to the opposite end of the lever, may pass above the motor.

The link 26 and a similar link 27 on the first end of the lever 211 are provided with hooks 28, whereby they may be attached to opposite ends of the car.

One or both of the toggle arms may be provided with a turn-buckle 29, whereby the wear in the shoes la may be taken up, to provide an accurate adjustment.

It will thus be seen that there is provided a new and improved bra-king mechanism of an efcient character and in which the links connected to the lever 24 may pass above and below the motor usually found in an intermediate position.

While I have shown one embodiment of my invention I do not v. ish to be limited to the specific details thereof, but desire to be protected in various changes, alterations and modifications which may come within the scope of the appended claims.

Having thus described my invention, I

. claim as new and desire to secure by Letters Patent:

1. The combination with a car truck having wheels to support the same, of brake shoes adapted to engage said wheels, hangers for supporting said brake shoes on said truck, toggle arms engaging said brake shoes and pivotally connected together, a brake shaft on said truck, a link connecting each pair of said toggle arms to said brake shaft, a lever arm for operating said brake shaft and secured thereto, alink connected to said lever arm, a diagonally-disposed lever having an inclined pivot connected to said last-mentioned link and adapted to operate the same, and links connected to said lever' fatvopposite sides of vthe pivot thereof and extending in opposite 'directions Vin vertically spaced relation.

2. The combination with a car truck having wheels t0 support the same, of brake vshoes adapted to engage the wheels, hangers for supporting said brake shoes on said ear, toggle arms engaging said brake shoes and pivotally connected together, a brake-shaft on said truck having a pair of short angular arms, a link connecting ea'ch oflsaid short angular arms to apair of said toggle arms, a lever arm carried by the brake shaft and depending therefrom, a link pivotally connected to the lower end of said lever arm, a diagonally disposed lever having an inclined pivot andhaving connection with said last-mentioned link at one side of its pivot, and links connected to said lever at Vopposite sides of the pivot thereof and ex- Copies of this patent may lge obtained forlve cents each, by addressing the Commissioner of Iatents.
