BRAKE FOR ELEVATED RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 510,292, dated December 5,1893.

Application filed March 29, 1893.

To all whom it may concern:

Be it known that I, WATSON L. REYNOLDS, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new 5 and Improved Brake for Elevated Railways, of which the following is a full, clear, and we act description. g'lhe object of theinvention is to provide an improved brake, especially adapted for use on elevated railways, and which will have an improved gripping action on the track rails, as hereinafter particularly described and claimed.

Reference is to be had to the accompanying drawings forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a carriage provided with my improved brake, and a portion of the track, the carriage being designed for suspending a car. Fig. 2 is a transverse sectional elevation, the section being taken substantially on the line 22, Fig. 1. Fig. 3 is a plan view, the track being in section on line 3-3, Fig. 2. Fig. 4 is a detail per spective View, on a large scale, illustrating one pair of brake shoes; and Fig. 5 is a detail perspective view showing certain details of the brake operating devices.

The carriage and the track and rails form no part of the present invention. Their construction is briefly as follows: The carriage comprises a frame work B, running wheels 0, and the safety wheels D,of which the run- 3 5 ning wheels 0, ride on the track rails E,

while the wheels D travel beneath such rails.

The rails E, as shown, are T-shaped in cross section,theT-l1ead being disposed vertically,

and the stem of the T being secured to the lower flanges on the I-beam F, of the track,

one of the rails E being thus located at each side of such beam.

The brake shoes A, are arranged in pairs,

as best shown in Fig. 4, to bear upon the top and bottom of therails E, which may be of any suitable form other than that shown.

The shoes are pivotally secured in pairs to a bracket or yoke A, secured to a rock shaft A the shaft having bearings in the frame B at each side of the track, as at a. The yokes Serial No. 468,135- (No model.)

A are each bent into U-shape at top and bottom to receive the shoes A, and the pivot bolts a are passed through such yokes and loosely through the shoes. At the back of each brake shoe a bowed plate spring a is placed between the shoe and the bend of the U-shaped terminal of the yoke, and a set screw a threaded into the yoke is adapted to bear on the spring at about its center, thus causing the ends of the spring to press 6c on the back of the shoe at each side of the pivot, thereby maintaining the shoes in parallel and permitting them to yield and accommodate themselves to the rail when the yokes are rocked as hereinafter explained. To the squared outer ends a of each rock shaft A is secured the upper end of an arm A and to the lower ends of each arm A there is secured one end of a link A the op posite ends of such links being secured to the arms A of the shaft A, which extends transversely through the frame B, one of the arms A being extended downward beyond its link A to provide a lever A for throwing the lever mechanism described and thus by the rocking of shafts A causing the shoes A to bear firmly against the top and bottom of the rail.

Any suitable means may be employed for throwing lever A such as a chain A leading in practice over suitable rollers (not shown) to the car platforms, to be actuated by the attendant in any suitable manner.

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

1. In a railway brake, brake shoes arranged in pairs, pivotally supported from a common rock shaft and spaced apart to embrace a track rail, and means for rocking the shaft, 9c the rocking of the said brake-shoe shaft serving to apply and release the brakes, substantially as described.

2. In a railway brake, a brake shoe pivotally supported from a rock shaft, for operation against a track rail, and having a plate spring bearing by its ends on the back of the shoe, the rocking of the said brake-shoe shaft serving to apply and release the brakes, substantially as described.

arms to the first named ones, substantially as described.
