AUTOMATIC UNCOUPLING DEVICE.

SPECIFICATION forming part of, Letters Patent No. 368,157, dated August 9, 1887.

Application filed May 9, 1887. Serial No. 237,598. (No model.)

To all whom it may concern:

Be it known that I, GEORGE J. LUBBERING, a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Auto matic Uncoupling Devices, of which the following is a specification.

This invention is especially adapted to be used upon coal-cars as employed upon elevated trackways. It is adapted to be used on all cars which are attached to cables, and more especially to that class which are attached to one end ofa cable.

The object of my invention is to automatieally uneouple acar as it arrives at the point of destination, all of which will be set forth in the description of the accompanying drawings, making a part of this specification, in which Figure 1 is a plan view of the elevated trackway, and the frame of a car with my improvement attached. Fig. 2 is a perspective View of the uncoupling device. Fig. 8 is a top plan view of Fig. 2.

1 represents the track way; 2, the ties or sleepers supportingthe track; 3, the car-trucks; 4 the cable for pulling the car; 5, the car-axle; 6, the coupling-bar provided with slot 7, into which the eye 8 of the cable-swivel enters. 9 represents the other portion of the swivel attached to the cable 4.

10 represents an oscillating lever pivoted to the aXle by a bolt, 11.

12 represents a lug or downwardly-projecting arm of the lever.

13 represents a draw-bar carrying the bolt or pin 14. on its inner end. This pin passes through eyes formed in the end of the drawbar 6, which is preferably made by doubling over the metal and welding the two parts together, as shown in Fig. 2.

15 represents a spriugcompressing-rod. It is supported by car 16 on the lever 10 and by car 17 on draw-bar 6.

18 represents the head, forming the springseat at one end, and the car 17 forms the other seat of the coiled spring 19. The spring 19 normally holds the lever 10 and drawbar 13 in the position shown in Figs. 1 and 2, and the bolt 11 passes through the eyes of the drawbar and the swivel-eye 8, in which position the car is securely coupledto the cable 4.

In order to automatically uncouple the car, a tripping-block, 20, is placed in proper position upon the ties of the track,-so that the lug 12 of lever 10 will strike the inclined edge 21 and, as the car passes along, will pull the lever 10 and the draw-bar 13 into the position shown in Fig. 3, releasing the coupling or con-- nection of the car to the cable. The spring automatically pulls the coupling-bar back into position.

In Fig. 1 the illustration represents the two ends of an elevated trackway for coal-cars, and two tripping-blocks 20 are in position to uncouple the car at each end of its route while in motion, and allow the car to go forward to its destination.

This contrivance is very cheap, simple, and effective, and avoids danger to the operator in uncoupling the car.

Having described my invention, what I claim as new is 1. The uncoupling device composed substantially of the lever 10, coupling-arm 13, draw-bar 6, slotted to receive the eye of the cable, and the tripping-block 20, attached to the track, substantially as specified.

2. In combination with the axle of a car, the slotted draw-bar 6, the coupling-arm-13, the lever 10, and the spring and rod attached to the draw-bar and lever, substantially as specified.

3. In combination with the uncoupling device consisting of the lever 10, draw-bar 6, the coupling-arm 13, the compressingspring 19, operated by the lever 10, and tripping-block 20, substantially as specified.

In testimony whereof I have hereunto set my hand.

GEORGE J. LUBBERING.
