HERMANN BIERMANN, OF BRESLAU, GERMANY.
ARRANGEMENT FOR PREVENTING ACCIDENTS ON RAILWAYS.
SPECIFICATION forming part of Letters Patent No. 596,047, dated December 28, 1897. Application filed March 20, 1896. Renewed May 21, 1897. $e1'lal No. 637,625. (No model.)
merchant, of Paradiesstrasse, Breslau, in
the Kingdom of Prussia, German Empire, have invented new and useful Improvements in an Arrangement for Preventing Accidents on Railroads with Running Trains in Case of Breaking of Axles, wheels, or Springs, of
which the following is a specification.
By this invention there is provided apparatus for the prevention of railway-trains leaving the rails. I
In carrying out this invention regard has been had to the fact that, in the case of wheels or axles breaking the carriage slightly drops at the part where the breakage has taken place.
According to this invention each of the Wheel-axles is surrounded by a forked frame bearing two running-rollers which are so arranged as to come slightly above the rail 'when the train is in motion and only to come in contact with the rail when the carriage drops in consequence of breakage of awheel or axle. The rollers then serve as supports for the carriage, thus enabling the carriage to travel a short distance farther on the rail when theaccident takes place. At the same time they also actuate an electric apparatus which is connected with an alarm appliance and also with the brake or with the enginedrivers lever.
In the annexed drawings, Figure 1 shows the apparatus attached to a'railWay-carriage; Fig. 2, a View of the forked frame; Fig. 3, the arrangement of the electric contact; and Fig.
4, the connection between the frame, the alarm appliance, and the air-brake.
With reference to the drawings, a denotes the frame, which is arranged in a strong and long guide-box c by means of a pin 1), the box being arranged at the bottom of the carriage above the wheel-axle. The pin b rests on the box iby means of a ring cl and holds the frame a, with its running-rollers f, slightly above the rail. In adjusting the rollers the oscillation of the body of the carriage on its springs must be taken into consideration, and there must therefore be some provision by which the position of the rollers f can be altered vertically. When the carriage drops slightly in consequence of the breakage of a wheel or axle, the running-rollers f come into contact with the rail. The running-rollers are so strongly constructed that they enable the train to travel on for a short distance and prevent the carriage from falling over. As soon as the running-rollers f come into contact with the rail the dropping of the carriage at the same time causes a spring electric contact g, arranged at the bottom of the carriage, to be closed by means of the pin b, so that the current of an electric circuit 2', fed by an accumulator-battery h or some similar arrangement,is brought into action. In the circuitt'an alarm apparatus 70 and a motorl are provided. The shaft of the engine Zhas a toothed wheel m, which gears into a toothed. quadrant 0, which is connected with the lever n of the air-brake. There may also be inserted in the electric circuit 2' a means of working the engine-drivers lever or other appliance.
The above-described device acts in case of Wheel and axle breaking as well as in spring breaking.
Having now described my invention, what I claim, and desire to secure by Letters Patcut, is--- In an arrangement for preventing accidents on railroads the combination of forked frames provided with rollers and surrounding the wheel-axles and engaging with the rails in case of wheel, axle or spring breaking with an electric circuit in the train and connected with safety and alarm apparatuses; said electric circuit including a contact device adapted to be operated by the forked frame as and for the purpose set forth.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
