SAFETY DEVICE FOR. RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 320,390, dated June 16, 1885,

Application filed June 9, 1884. (No model.)

To all whom, it may concern.-

Be it known that we, SIGWARD PEDERSEN, a resident of Chicago, Illinois, and THOMAS SERNENDINGER, of Philadelphia, Pennsylvania, both citizens of the United States, have invented certain Improvements in Safety Devices for Railway-Cars, of which the following is a specification.

One object of our invention is to preventinjury to persons or property falling upon the track in advance of the wheels of a streetcar or like vehicle, another object being to insure the quick stoppage of the car when there is an obstruction of any character upon the track. These objects we attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a longitudinal section of part of a street-car with our improvements Fig. 2, the same with some of the parts in a ditferent position; Fig. 3, a transverse section of part of the car; and Fig. 4 a detached view, on a larger scale, of a brake-wheel, forming part of our invention.

A is part of the frame of the car, and B one of the axles of the same, to which, at the most available point, is secured a brake-wheel, 1), preferably constructed as described hereinafter. Beneath this wheel is a bar, F, hung at the front end to a bracket, a, on the frame, and acted upon by a spring, I), which tends to depress it, the rear end of the bar resting upon a cam, d, on a rock-shaft, c, which is adapted to bearings in a hanger, i, and has an arm, f, connected by a rod, 9, to an apron, G, hung to the front portion of the frame, and of such length that its lower edge isbut a few inches above the track. Under ordinary circumstances the apron hangs vertically, and the bar F is free from contact with the brakewheel, as shown in Fig. 1, but in the event of the apron meeting with any obstruction it is forced rearward, as shown in Fig. 2, thus, through the medium of the rod 9 and arm f, operating the shaft 0 and its cam d, and cansin g the elevation of the bar F, the upper edge of the latter, which is preferably roughened, as shown, being thereby pressed forcibly against the brake wheel 1), so as to prevent the further rotation of the same and the axle and stop the car. Persons falling upon the track are thus prevented from being crushed by the wheels, the tendency of the apron being to sweep them forward on or off of the track without injury while the car is moving the shortdistance previous to its being stopped by the brake. Damage to valuable property falling upon the track is likewise prevented, while on the other hand the car cannot be derailed by contact of the wheels with obstruc tions upon the track.

To prevent persons or property falling upon the track between the wheels, we use guards H, hung to the sides ofthe car and hanging down to within a short distance of the ground, the front edges of these guards extending to the front of the car-body and serving as guides for the apron G, projections m on the latter bearin g on the ends of the guards II, as shown in Figs. 1 and 2. Ihese guards II have openings II for the axle-boxes 13, as shown in Fig. The lower edge of the apron, and

preferably also that of each guard II, is fur-- nished with a strip, p, of rubber or other elastic 1naterial,so as to relieve the shock caused by striking any object upon the track, and prevent injury to the person by violent contact with the guard or apron.

Various forms of brake-wheel may be adopted for instance, the wheel may be clothed with wood or rubber; but we prefer a wheel made as shown in Fig. 4,in which srepresents a block of rubber made in sections so as to be fitted to the axle and confined be tween opposite disks, t 1, also made in sections for convenience in fitting them to the axle, to which they are bolted or otherwise secured. The disks have internal prongs, y, which project into the rubber blocks and efi'ectually prevent the turning of the same independently of the disks. Bolts, a, passing from disk to disk through the rubber block, also aid in preventing the block from turning, and serve to confine the disks laterally to the block and prevent spreading of the latter.

IVe claim as our invention- 1. The combination of the axle having a brake-wheel, 1), the bar F, the pivoted apron G, and devices, substantially as described, whereby on the yielding of the apron the bar is pressed against the brake-wheel, as set forth.

2. The combination of the apron G, the axle names to this specification in the presence of and its wheel D, the arm F, and. the rock-shaft two subscribing witnesses.
