TRACK-BRAKE FOR CARS.

SPECIFICATION forming part of Letters Patent No. 376,363, dated January 10, 1888.

Application filed June 9, 1887. Serial No. 240,754.

To all whom it may concern.-

Be it known that I, J OHN- S. BOKEKNKO'ITER, of Norwood, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Track-Brakes for Cars, which improvement is fully set forth in the following specification and accompanying drawings, in which-- Figure I is an under perspective view of a street-car to which my invention is applied; and Fig. 2 is a transverse view forward of the locking device, showing the latter in engagement with the rails.

The object of my invention is to provide an efficient and simple device, whereby street;

railway and incline cars may be readily and reliably stopped; and it consists of parts hereinafter described, reference being had to the accompanying drawings by suitable letters and figures corresponding to like letters and figures in specification; and it consists of an operative mechanism,whereby apair of brake- V shoes are brought laterally into engagement with the innersides of the rails, taking alocking-hold under the caves of the rail-crown.

In order to carry my invention into effect, I provide on either side between the wheels a downwardly-projecting arm or stud,A,rigidly secured to the bottom of the car A. Upon this studis a sleeve, B, which conforms in shape thereto, and which slides up and down a limited distance, for purposes hereinafter set forth. This sleeeve B'hasits lower end turned laterally, forming a rigid integral extension.

, formed oblong,

Projecting outwardly from the sleeve isa stud, E, carrying a friction-roller, F1 Upon this lateral extension is formed integrallya second sleeve, 0, into which sleeve is placed a sliding plate or short bar, D, which moves laterally with respect to the car. This plate D is at a suitable point turned vertically downward, thence outward, the latter portion being and outwardly somewhat rounded. j

In order to bring the device into action, two movements are required-viz., a downward movement of the main sleeve B upon the stem A and an outward movement of the lockingplate against the rail P. The first movement is effected by using the following mechanism: A vertical shaft, Q, provided at its top with (No model.)

a handle, R, working over a notched segment, S, is suitably journaled, and extends beneath the bottom of the car, its lower end provided with vertically-proj ecting arms U U. To these arms are respectively secured connecting-rods T T. The other ends of'these rods join to the forward ends of stiff bars V V, that extend rearwardly to and connect with the sliding lock-plates at P P.

About midway of the bars V'thereis a rigidly-pendent plate, L, secured to the bottom of the car. This plate is provided with slots through which the bars V pass, and which slots serve as fulcrum-bearings for the bars in operating the sliding lock-plates D.

The vertical movement, which i'eally should have been described first, is accomplished by the following mechanism: Pivotally secured to the pendent plate L is an arm, 0, which rearwardly of the plate is formed with two prongs,Y, extending, respectively, to the vertical sliding sleeves upon the vertical pendent rigid stem. These prongs are provided with slotted or forked terminations to engage with arigid stud, J, projecting from the sleeve, so as to compel its movement up or down on the stem when required. The forward extension of the pivoted arm is, by means ofa short conmeeting-rod, T, joined to a foot-lever, G. This foot-lever extends upwardly through the bot tom of the platform and terminates with a foot-plate within easy reach of the operator.

Although my device is eminently adapted to street-cars, it is obvious that the sphere of its usefulness extends much farther, and will be applicable to railroad-cars, or cars of any description operating on rails.

Having described my invention, what I claim as new is- 1. A locking device for cars, consisting of retractile plates brought into and out of engagement with the sides of 'thetrack-rails, said plates being operated by adual system of compound leverage, mounted as described, and

terminating forwardly with suitable engagement-points in reach of the operator, substan tially as herein set forth.

2. A brake for railway-cars, consisting of two pendent arms on the lower side of the car-body, one on each side, each carrying a sleeve provided with an inwardly-projecting brake-bars, and a pulley or friction wheel on the outside of each vertical sleeve,which rests on the track when the sleeve is depressed, 15 substantially as herein set forth.

right-angled or horizontal sleeve at its lower I end, said horizontal sleeve having therein a horizontal sliding bar with its outer end depressed or bent downward and provided with a shoe which comes in contact with the inner In testimony that I claim the foregoing I side of the railway-rail, said sleeve and brakel have hereunto set my hand, this 24th day of bar being manipulated by suitable levers in I February, 1887, in the presence of two wit reach of the brakeman, substantially as here- I nesses. in set forth.
