IMPROVEMENT IN COUPLINGS FOR ST EAM OR AIR BRAKES.
Specification forming part oi Letters Patent No. 123,776, dated February 20, 1872.
Specification describing certain Improvements in Steam, Air, or other Pipe-Couplings for Railroad Cars, by SAMUEL N. GOODALE, of St. Louis, county of St. Louis, Missouri.
My invention consists of two devices to accomplish the object, and may be classed as double and single coupling: The first may be used on railroad cars for connecting-pipes which convey any compressed power to the cylinder and brakes on such railroads as oocasionally or frequently reverse their cars from end to end, while the latter or single coupling is more simple, and may answer between such cars as are never turned around. Either of these couplings makes a tight joint, through which steam, air, gas, or any other substance may be used.
Figure 1 is a side elevation of my double coupling. Fig. 2 is an end view of the same.
Fig. 3 is a side elevation of a single coupling. Fig. 4 is an end View of same.
In Fig. 1, A is the double coupling, made of brass or other metal, having on each end a ground-joint, D, which is inserted into another ground-joint, which is attached to a flexible hose, or directly to the connecting-pipes. In either case a shoulder is provided having on one side an incline, B B. This shoulder has also a groove, through which, as it is coupled, it passes a steel spring with a point projecting, as at O O. This spring is firmly attached to the double coupling A, and, as it is turned, by hand or otherwise, is made to draw the connectingpipes or hose together, making them steamtight. Fig. 3 shows the single coupling, with male and female groundjoint D. (-J represents the springs, which are made elastic, so that, by switching or running a car from the track, it will be more readily separated without breaking the'pipes or hose. To aid in coupling and uncoupling, handles are provided, as
indicated by E, and the flexible hose connect,
