D. J. PARMELE, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO HIMSELF AND J. H. CURRIER, OF SPRINGFIELD, ILLINOIS.
IMPROVED RAILWAY-CAR BRAKE.
Specification forming part of Letters Patent No. 84,963, dated December 15, 1868.
To all whom it may concern:
Be it known that I, D. J. PARMELE, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Car-Brake; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference bein g had to the accompanying drawings forming part of this specification.
rlhis invention relates to improvements in car-brakes such as are operated by the power of the moving train. It consists of an improved arrangement of mechanism for instant- 1y throwing a pair of friction-wheels into gear, to the shaft of one of which the brake-chain is attached, the other being arranged on the caraxle.
Figure l represents a longitudinal sectional elevation of a car with my improved apparatus applied thereto. Fig. 2 represents a plan view of the bottom of the same, and Fig. 3 represents an end view of the same.
Similar letters of reference indicate correspondin g parts.
A represents a frictionwheel, made of vulcanized rubber or other suitable material, and arranged upon the car-axle. b represents a similar wheel arranged on a shaft, c, having one stationary bearing and one movable in a vertical direction. The cord or chain d for operating the brakes is attached to the shaft c in a manner to be wound thereon when the said shaft rotates. The movable bearing of the shaft c is arranged on the lever c pivoted to the bottom of the car at f, and connected at its other end to the vertical rod g, which terminates at its upper end in a hook which takes over the segmental hook IL of the swinging trigger i. By this arrangement the frictionwheel b is held out of contact with the wheel a. lc represents a cord running from one car to another of a train, and having rings suitably connected to it to take over the upper ends of the said triggers, so arranged that when it is desired to set the brakes into operation the pulling of the rope by the brakeman or the en gineer will swing the triggers so as to disconnect the hooks It from the hooked upper ends of the rods g and allow the friction-roller b to fall upon the roller a and be set into motion to wind up the brake-chains d in a manner well known. The rings in the cords k, after tripping the rod g, will slip off the upper ends of the triggers and allow the rope to be drawn sufficiently to trip the brakes of other cars, as may be desired.
1n this manner the brakes of all the cars may be set into operation by one person; or only one or a port-ion of thebrakes maybe set in operation.
When it is desired to throw the brakes out of action the brakeman will be required to go from one car to another and raise the rods g` and hook them onto the triggers, and also place the rings over the ends of the triggers.
Handles may be suitably connected to the said rodsfor raising them. The rods g may be weighted, if required, to give additional adhesion of the friction-wheels.
I claim as new and desire to secure by Letters Patent- The combination, with the lever e, of the hooked rod g, hooked trigger 1'., and cord k, provided with rings, substantially as and for the purpose described.
