STEAM-PIPE COUPLING FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 602,821, dated April 26, 1898.

Application filed March 30, 1897.

T0 aZZ whom it may concern.-

Be it known that I, CHARLES E. BENSON, a citizen of the United States, residing at Wallingford, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement Applicable to the Steam-Pipe Couplings of Railway-Cars, of which the following is a description, reference being had to the accompanying drawing, wherein the figure is a side view of the apparatus embodying said improvement with one of the sphere-boxes and its sphere represented as cut in a vertical section with which the axis of the sphere coincides. This section is longitudinal of the cars to which the apparatus is attached.

The object and purpose of the improvement is denoted by its title, it practically being a coupling, with its parts attachable to and detachable from each other, for connecting the steam-pipes now ordinarily carried beneath railway-cars.

In the accompanying drawing the letter a denotes a part of the railway-car, practically a cross-timber at the front end of the platform, and the letter I) denotes a loop ordinarily carried by such a platform encircling ordinary car-coupler parts.

The letter 0 denotes what may be termed the sphere-box, practically a chambered casting attached by bolts to theloop b. The ordinary steam-supply pipe lets steam into the chamber of this sphere-box through the orifice (Z. The letter e denotes What is practically a metallic sphere of true and regular outline hung in said sphere-box and universally rotatablethat is, rotatable in any direction. It is held to its seat by the spherecollar f, which is exteriorly screw-threaded and takes into a corresponding interior thread carried by the sphere-box.

The letter 9 denotes packing which makes a fluid-tight joint between the sphere and the sphere-box.

The letter h denotes a set-screw for holding the sphere-collar firm and fast in any desired adjustment. The screw takes its bearing upon the sphere-collar through the intermediate soft-metal cushion i, so as not to injure the screw of the thread.

The letter 7.; denotes a tube adapted to have Serial No. 630,016. (No model.)

both reciprocatory and rotary motion in the sphere e.

The letter Z denotes packing which makes a fluid-tight joint between said tube and said sphere, said packing being held to place by the tube-collar m. That tube-collar is held to any desired adjustment by the set-screw n, which bears upon the thread of the tube-collar through the intermediate soft-metal cushion 0.

The letters f denote wrench -sockets by which the sphere-collar may be rotated.

The letter m denotes wrench-sockets by which the tube-collar m may be rotated.

In order to be able to hold the sphere e and tube is from rotation while one rotates the tube-collar m, there is a hexagonal or many sided cap p, fixedly attached to the tube in, which will drop into and fit to the mortise e in the sphere. As a consequence of this construction a person can grasp the tube is with a pipe-wrench and hold it and the sphere nonrotatable while one rotates the sphere-collar f.

The letter r denotes, as a whole, a checkvalve, which will stay closed when there is a normal pressure of steam in the sphere-box; but the moment that pressure is released it will open under the influence of its spring and permit the water of condensation to escape from the sphere-box.

The tube It is designed to be of a suitable metalbrass, for instance-as far as the pipecoupling t and of iron or the like below that. It is intended in the summer time, when it is not necessary to use this apparatus, to detach the lower iron part of the tube and close the stub with a plug.

Each of the tubes It has a proper chain-support it. Each is equipped with one of the cooperating joint parts, the construction and operation of which are matters well known in the art. It is necessary in attaching and detaching these joint parts from each other that the tubes is should be capable of various movements, all of which are permissible by means of the construction of parts hereinbefore described. The joint parts '0 and 12' may well be those of the well-known Sewall coupling.

I claim as my improvement- In combination, the sphere box, the unitatableas to each other, all substantially as versally-lrotatable sphere hung in said box described and for the purposes set forth. with fluid-tight joints between the two, the tube adapted to have reciprocation and rota- 5 tion in said sphere with fluid-tight joints be- Witnesses:
