CHOCK AND GUARD FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 502,145, dated July 25, 1893.

Application filed April 8,1892. Serial 110.428.314- (No model.)

To alt whom it may concern:

Be it known that I, WILLARD T. SEARS, of Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Chocks and Guards for Railway-Cars, of which the following is a specification.

Myinvention has relation to car fenders and brakes; and it has forits purpose the provision of means attachable to a street or other railway car which may be automatically operated, in case a person or any unusual objeot is encountered upon the track, so as to be brought into position to prevent such person or object from passing under the wheels or such parts of the car as would do serious harm, and whereby, also, the wheels of the car may be automatically. chocked and the progress of the car effectually stopped.

To these ends my invention consists of a fender for cars comprising the construction and combination of parts as hereinafter described and claimed.

Reference is to be had to the drawings hereto annexed, and to the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may. be, wherever they occur.

Of the drawings: Figure 1, is a side elevation of part of the truck and body of an electric street railway car, as now commonly constructed. Fig. 2, is a top plan view of the same. Fig. 3, is a side elevation of the lower portions of the body, truck, and truck frame of a horse railway car. Fig. 4, is a top plan view of the same. I

In the drawings: adesignates the car body.

I) is the platform, in front of the splash board 0 on the forward end of which, as shown in Figs. 1 and 2, are arranged the means for controlling the brakes and motor.

at designates the truck-frame supporting the journal-boxes for the bearings of the wheels 6.

f designates bars or levers at the sides of the car, each pivotally connected at a point intermediate of its ends with one end of a link bar g, the other end of which is pivotally connected with a suitable part of the truck-frame. At their forward ends the bars f are connected with the ends ofa fender, which may be of angular form as shown, or of any other suitable shape, which fender may consist of a bar h of necessary strength and width provided on its lower face with a brush i of rattan, reeds, or other flexible material, which extends normally to a line safely escapingthe surface of the road or pavement, anditslower surface may be made to conform to the common curved form of the road-bed between the rails.

j designates a frame secured to the truck-, frame and extending forward under the platform 17, and having springskconnected therewith and with the fender to support the latter in normal position. The said springs 10 will be of such strength as to hold the guard up from the road-bed under ordinary circumstances but so as to yield, and allow the guard to be depressed in case it encounters any unusual object on the track.

Z designates a chock secured to the inner end of each barf over each rail, so that in case the guard encounters an obstacle onthe track and is (as it will be) depressed thereby, the chock Zwill be swung inward and carried downward through the medium of the bars f and link bars g upon the rails and wedged between the same and the tread of the wheels. The surfaces of the chocks may be serrated so as to more fullyimpinge upon the surfaces of the rails and the tread of the wheels, and the height and form of the chocks maybe such as tocause them to act against the brake or brake-cushions of the wheels.

In the use of my invention it will be seen that should a person or any unusual object be encountered on the track, such person or object coming into contact with the fender will immediately depress the same so as that the brush will be brought into contact with the road-bed and prevent the said person or object from passing under the fender or car. At the same time the chock Z will have been automatically forced inward and downward, so as to have become wedged between the rails and wheels and eifectively chocked the latter and stopped the progress of the car. It is to be noted that it would not be without the scope of my invention if the fender and chock were constructed so as to be depressed or otherwise actuated by means under the control of the driver or motorman.

I have contemplated the use of means of Ioo different form and arrangement for supporting and actuating the fender and chock, some of which include modes of using them independently, and in some cases employing one without the other; but in all it is proposed that in case an unusual object is encountered on the track the chock shall be interposed between the rail and tread of the wheel as described.

Ilaving thus described the nature of my invention and explained away of constructing and using, the same, though without attempting to set forth all of the forms in which it may be made or of all the modes of its employment, I declare that what I claim is i 1. A fender for cars, comprising in its construetion a brush, and springs connected with the fender and car body or truck or trucktwo subscribing witnesses, this 6th day of 0 April, A. D. 1892.
