To all whom it inag ronce'rn Be it known that I, IIALBERT E. SMrri-r, a

' citizen of the United States, residing at Seibert, in thecounty of Kit Carson and State of Colorado, have invented certain new and useful Improvements in Train-Pipe Couplings; and I do hereby declare the follow- Ing to be a fuILclear, and exact description 1 -of the invention, such as will enable others v make and use the same.

This invention relates to improvements in I skilled in the art to which it appertains to pipe couplings especially designed for cong necting the air pipes upon railway cars.

The invention has for its object to provide a train pipe couplingof simple and efiicient whereb construction including a novel typeof joint,

a limited lateral swinging movement the'free ends of the coupling is permitted, thereby facilitating relative move ment of the adjacentends of cars of a train. Another object is the provision of a simple and efficient guardor protective housing for l coupling, partly broken way, illustrating a the couplingdesigned to prevent injury to i the coupling duringtraveling of the train.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of arts as-will be hereinafter specifically descri ed, claimed andillustrated in the accompanying drawing in which:

Figure 1 represents a side elevation of the I fragment of a railway ca Fig. 2 represents a fragmentary longitudinal sectional view through the coupling. Fig. 3 represents a "fragmental detail view of one of the cou- {pling elements removed. Fig. l repr'esents a horizontal sectional view on the line 4-4 of Fig. 1. Fig. 5 represents a detail sec' f. tional view on the line 5-5 of Fig; 1, and-j Fig. 6 represents fa fragmental detail view.

of the valve in the coupling pipe.

Referring to the drawing in detail, where.

in similar reference numerals designate corresponding parts throughout the. several :views, the numeral 8 indicatesthe mam air pipeywhich is connected at each end of the car with a horizontally disposed cylinder 9 rigidly secured beneath the car and stationary relative thereto. A longitudinally slidable couplinglpipe 10 is slidably" mounted through the outer headvll of each cylinder 9, projects into the latter and is normally retained in outwardly extended position by the tension of a sprlng 12 engaged at one the corresponding flange. o

and with the inner end of the cylinder and at the opposite end with the flanged extremity 13 of the slidable coupling pipe 10. A substantially C shaped pipe 14 isconnected at its central or web portion in the outer extremity of the coupling pipe 10 and the spaced vertically alined free ends ll? thereof are pivotally connected with the 1101- low head 16 of the coupling pipe 17 movable upon avertical axis. A suitable type of valve 18 is arranged in the slidable coupling pipe 10 intermediate the flange 13 and joint pipe 14 for controlling the passage f fluid through the coupling'pipe and operable by a rod 19 extended laterally of the car, which latter is designated generally by the numeral 20. l

Alhanger designated generally by the numeral 21 for supporting the slidable coupling pipe 10 and C pipe 14: includes a track 22 suitably secured .to the car and a roller 23 movable longitudinally upon the track 22 and connected-with theupper ver tical member oi the C shaped pipe 14: by' a bracket 24.

A hollow tubul r plunger 25 is slidably mounted within and projects a'distance outwardly of the outer end of the pivoted cou-' plingpipe 17 and is provided with a flared.

inner end 26 snugly fitting vwithin said tremity26 of the slidable plunger 25 and at g A its-opposite end with an annular flange 28 formed adjacent the inner extremity of the pivoted pipe 17-. A pair of gaskets 29 hay mg peripheral grooves are positioned upon the plunger 25 and are slidable thereon and receive the angular flanges 30 and 31 ofthe plunger'25 and a coupling sleeve 32, respectively. An annular sealing cushion or gasket 33, formed of rubber or other suitable let.

material, is removably secured ii -the outer end of the sleeve 32 and is provided with anoutwardly directed flange 34 overlying the end of the sleeve 532 and ada ted to engage the coupling car soa's to provide an air tight coupling between the hollow plungers 25 in the coupling members at the adjacent ends of the cars.

l rusto-c'oiiical guards 36 are. secured at their small ends to the pivoted coupling pipes 17 and are adapted to engage each other at their relatively large ends, as illustrated in Figs. 1 and 2 when the carsare Y secured tothe slidable pipe, and a spring actuated coupling member carried by the 5 couplingmember' carried by said plunger.
