SPECIFICATION formingpart of Letters Patent N o. 658,031` dated September 18, 1900.

vApplication filed November 4, 1899. Serial No. 735,745. (No model.)

To all whom it may, concern:

Be it known that I, WILLIAM T. VAN DOEN, acitizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Railway- Cars; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accom panying drawings, which form a part of this speciiication.

Myinvention has forits object the production of mechanism to prevent the derailing of railway-cars.

The invention is applicable to either what are generally known as steam-railroads or to street-railways.

It consists in a combinationof devices and appliances hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation,with parts in section,of a railway-car axle and adjacent mechanism. Fig. 2 is an end elevation of the same on a reduced scale.

In carrying out the invention, A represents the car-axle; B, the Wheel; C, the journalbox; D, the rail, and E the railway-ties.

t. The Aabove parts are of the usual or ordinary construction, and as my invention is applicable to any of the ordinary or usual forms or constructions of railway-cars I have only shown the parts mentioned.

Instead of the axle terminating in the journal-box C, as is ordinarily the case, I extend the axle through the end of the journal-box and key to it in any suitable manner-as, for instance, by the set-screws f-two collars F F. Between these and journaled -on the axle is what may be termed an antifriction roller Gr.

H represents one of a series of arms or braces, preferably made of angle-iron in cross-section to give the requisite strength, securely engaged to the tie E, on which the rail D rests, by bolts I-I and a plate H', the idea being to make the arm H so securely engaged to the tie that any elevations or depressions of the tie will carry the arm with it. The arm is extended upward and laterally and is provided on its under side witha rail J, the head j of the rail being closely adjacentto or, if desirable, in contact with the antifriction-roller G.

The operation of the mechanism is obvious. Should the wheel B attempt to leave the'rail D, the roller G will at once come in contact with the railJ, and any further elevation of the wheel D will be thereby prevented, so that with my device as just described the derailment of the car is impossible.'

Of course the antifriction-roller Gr might, if desired, be dispensed With and the rail .l brought down, so that it will bear directly on the axle; but as more or less frictionwill be developed when the axle comes incontact with the rail J itis perhaps desirable to provide the antit'riction-roller G. So, also, if desirable, the arms H might be strengthened or braced by any of the Well-known means in the art Without departing from the' spirit of the invention. So, also, While I prefer to ex tend the axle to form the bearing against the rail .I yet any other form of bracing-arm might loe extended from the car to come in contact with this rail J, the idea being to provide on the car some sort of an extending arm which will come in contact with a continuous surface along the road-bed and prevent the abnormal elevation of the car-Wheels from the track.

What I claim isfl. In a railway-car, the,combination with the rotary axle thereof and its journal-box said axle projecting laterally beyond the j ournal-box, of a continuous rail or track above the end of the axle with Which it can come in contact when the axle is abnormally elevated, substantially as described.

2. In a railway-car, the combination with the journal-box and the-rotary axle extended laterally beyond the journal-box and pro vided on its end with an antifriction-roller, of a continuous rail or track above said roller against which the roller can bear when the axle is abnormally elevated, substantially as described. Y

In testimony whereof I sign this specification in the presence of two Witnesses.
