LOUIS SEILE, or VIENNA, AUSTRIA-HUNGARY.
AUTOMATIC RAILWAY-BRAKE.
SI PEGIFIGATION forming part of Letters Patent No. 737,029, dated August 25, 1903.
Application filed May 29, 1902. Serial No. 109,476. (No model.)
To all whom it may concern:
Beit known that 1, Louis SEILE, a subject of the Emperor of Austria-Hungary, and a resident of Vienna,Austria-Hungary,have invented certain new and useful Improvements in Automatic Railroad-Brakes, of which the following is a specification.
This invention intends to effect an auto-, matic putting on of the brakes in an absolutely sure way with railway-trains provided withcompressed-air, steam, or similar self-acting brake apparatus if a car is subjected to an excessive jolt by derailment, breaking of an axle, or the like. This is effected by providing a member upon one or all axle-bearings of the car, furnished with two stops in a certain height one above the other, while there are provided on the underframe of the car on fit places organs acting upon the brake as valves or as cooks, for instance. Such a brake-valve is opened by a swinging arm and in the same manner closed. Under ordinary circumstances {the lever-arm'rests half-way between the two stops of the above-said mom-- her and is not affected by the ordinary jolts. In the case of excessive jolts the; lever-arm of the brake-valve is hit by one of the two stops, and thus sets the brakes. This leverarm is constructed in such a manner as to discontinue the connection between the leverarm and the valve or similar organ as soon as the latter has been opened by the arm. If, therefore, a successive jolt or jerk should move the lever-arm in the opposite direction, this has no efiectupon the brake-valve. The brake-valve remains open, and the setting of the brakes is thus surely effected.
Figures land 2 represent the scheme of such an arrangement. Fig. 1 shows the position of rest; Fig. 2, the position of setting the brakes.- Figsr3 and 4 represent the lever-arm seen from above and from one. side.
The rod 77. is fixed in a suitable manner on the axle-bearing of a car, showing the two stops 0 and 0 adjustably secured in the position shown. The steering organ f, acting upon the brakes, is on the underframe of the car A and is influenced by the motions of a movable arm h If the arm k comes into the position represented by Fig. 1, the steering organ is so placed that it has no influence.
upon the brakes. The stops 0 o are so placed upon the rod n that they do not come into contact with the arm k by ordinary jolts. By, an excessive jolt, which renders the action of the train-brakes'necessary, one of the stopsas, for instance, the upper one 0-contacts with the arm h which is then swinging into the position represented by Fig. 2 and bringing thus the steering organ f in such a position as to act upon the brakes.
The steering organ f is closed or opened by turning the axle Z, on which before is wedged up a lever 0. This leverp has a pin en v gaging a longitudinal slot g on the rear part 65 of the prolongation h of the lever-arm 7L2, if f the lever-arm k and the lever 12 are in a horizontal position, Fig. 1. If by a stronger jolt the lever h is brought into an oblique position -as, for instance, that represented by '70 Fig. 2-the pin it is moving in the slot q into the interior-i. 6., toward the pivoting-point of the lever-hwhile the steering organ is opened by a turning of the axle g. As soon as the lever k h has come into a certain position-to, say, about forty-five degrees against the horizontal position-the pin gets into cross-slot 1', provided in the lever h, and will pass out from the slot qthrough the crossslot r, and thus become disengaged from the lever h by a further movement of the lever. If by a further jolting the lever is moved backward, the cross-slot r will pass above the pin 70 without acting upon the'lever por the braking organ.
What I claim, and desire to secure by Letters Patent, is
In combination, the brake-valve, an arm for operating the same, a pivoted lever having a longitudinal slot and a transverse slot leading therefrom to the sides of the lover, a pin on the arm engaging said slots, 2. rod connected with the truck and stops on said rod for contacting with said lever, substantially as described.
In witness whereof I have hereunto set my hand in presence of two Witnesses.
LOUIS SEILE.
