JOHN PAULAUSKI, OF CHICAGO, ILLINOIS.
SAFETY DEVICE.
1,1sav1o.
Application fiIed September 14, 1914.
To all whom it may concern Be it known that 1, JOHN PAULAUSKI, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety Devices, of which the following is a specification.
This invention relates to stops or safety devices for mine cars, the same being de signed to prevent the running away of a car on an inclined passage-way or gallery in the event of said car breaking loose from the train; and the invention has for its object to provide a simple and eficient device of this kind.
With the herein stated object in view, the invention consists in a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in'which Figure 1 is a plan view of the invention, and Fig. 2 is a side elevation thereof.
Referring specifically to the drawing, 5 denotes a passage-way or gallery in a mine, the same having a track 6 on which travel the trains of cars which transport the products of the mine. As shown in Fig. 2, the passage-way or gallery is inclined, in view of which provision is made for stepping a car if the same should break loose from the train; or to stop the entire train if it should get beyond control and start to travel back down the incline.
The safety stop device comprises a buffer beam 7 having a reduced rear end 8 which is slidably mounted in an aperture in a rigid horizontal bracket arm 9 mounted on the wall of the passage-way 5 and projecting outward from said wall in the direction of the track6. Between the bracket arm and a shoulder on the bulfer beam formed by the reduced end thereof, is interposed a coiled spring 10 which opposes the rearward or inward movement of said beam. The aperture in the bracket arm 9, through which the part 8 passes, is wide enough to allow the bufier beam to swing transversely of the track 6. A spring 11 between the buffer beam and the wall of the passage-way normally holds the former swung over toward the track a suflicient distance so as to be in the path of the cars traveling on said track. A chain 12 connecting the buffer beam to the wall of the passage-way limits the outward swing of the beam. The bulfer beam is supported in horizontal position by a brace Specification of Letters Patent.
Patented Apr. 20, 1915.
Serial No. 861,592.
ted in Fig. 1 As soon as the cars pass,
the bufier beam swings back to the full line position. If, however, a car on the train should start to travel down the incline, the buffer beam at once acts as a barrier to stop the same. The impact of the car or the train against the buffer beam slides the same rearward against the tension of the spring 10, and the latter therefore serves to cushion the movement of the beam.
A sufficient number of the hereinbefore described safety stop devices to adord complete protection will be mounted in the passageway or gallery.
I claim:
1. A safety stop device for cars, comprising a buffer beam mounted to swing transversely of the line of travel of the car and to move in the direction of its length, yielding means opposing the last-mentioned movement of the beam in one direction, yielding means normally holding the beam in the path of travel of the car, said means allowing the beam to swing inward when the car is traveling in one direction, and means for limiting the outward swing of the beam.
2. A safety stop device for cars, comprising a buffer beam, a bracket arm having an aperture through which the beam passes loosely, said beam being free to slide in the aperture and to swing therein, yielding means opposing the last-mentioned movement of the beam in one direction, and yielding means normally holding the beam in the path of travel of the car, said means allowing the beam to swing inward when the car is traveling in one direction.
3. A safety stop device for cars, comprising a buffer beam mounted to swing trans versely of the line of travel of the car and to move in the direction of its length, yielding means opposing the last-mentioned movement of the beam in one direction,
allowing the beam to swing inward when JOHN PAULAUSKI the car is traveling in one direction, means V V and a pivoted brace bar loosely connected S. J.LEHRER, to the'beam. H. G. BATCHELOR.
Copies of this patent may be obtained for five cents each, byaddressing the f Commissioner of Patents 7 Washington, D. 0.
