Original application illed March 9, 1922, Serial No. 542,297. Divided and this 1924. Serial No. 707,379.

[o all whom 'it may conce/Mt:

Be it known that I, EDWARD C. Postr, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Couplers, of which the following is a specification.

My invention relates to a hose coupling, especially a coupling intended for detachably uniting the hoses or equivalent flexible, metal, tubular elements on the ends of the train pipes of adjacent cars of a railroad train.

The primary object of my invention 1s to provide a novel, simple coupling of economical construction of which the mating coup- 1ers may be brought into a preliminary engagement by a lateral movement of one member toward the other (without the usual rocking or angular movements characteristic of the gravity type of coupling) and then drawn into fluid tight relation with thelr gaskets pressed one against the other to complete the coupling operation. More specifically, my invention contemplates the formation of one of the elements of the coupling with a projecting lug and the other with a sliding member which is forced into engagement with said lug, so as to draw the couplers. The term coupler is used to detric or equivalent device. By the term coupling I intend to include both mating couplers. The term .coupler7 is used to denote one of these members. The coupling may consist of two members, each constructed :n accordance with my present invention, but .a single coupler as constructed may be mated `with another coupler differently designed so long as the other coupler is provided with engaging parts of suitable configuration and properly placed to effect an interlocking engagement with the corresponding part of the other coupler.

The invention consists in the new and improved constructions, arrangements and devices to be hereinafter described and claimed vfor carrying out the above stated objects, and such other incidental objects as will appear from the following description of a preferred embodiment of the invention as shown in the accompanying drawing.

In the drawing:

Fig. 1 is a plan View, with certain parts in section, of a coupling of two identical couplers made in accordance with my invention. I

Fig. 2 is a side elevation `of the coupling shown in Fig. l.

Fig. 3 is a view, in perspective, `of the sliding member employed in the construction of the invention shown in Figs. 1 and 2.

Fig. 4: is a fragmentary view inelevation of the sliding member showing the other sidc of the same from that shown in Fig. 3, an

Fig. 5 is a view in perspective of the actuating cam for moving the sliding member of a coupler into locking engagement with another coupler as shown in Figs. 1 and 2.

In the drawing I have shown my improved coupling made up of two, preferably though not necessarily, identical couplers A and B. Each of these couplers consists of a head 10 provided with the usual fluid passage therethrough and with a gasket 11 of suitable construction fitted in theend of such fluid passage so as to bear against a corresponding gasket of the mating coupler when said coupling is in its assembled operative position. Thecoupler heads are each formed on one side' with an undercut lug 12 and on the other side with a forwardly projecting arm 13 having outstanding parallel flanges 14:, 15 between which is arranged a sliding member 16. This member is provided at its forward end with a head 17 projecting through an opening 18 in the arm and formed` with an undercut curved lug 19 adapted to engage the lug l2 on the mating coupler. The rear portion of member 16 .is formed with a recess 20 and with upper and lower slots 21, 22. The sliding member 16 is actuated by means of a rotary cam or eccentric 23 arranged in recess 20 of the sliding member and held in place by means of a stud 24 which is fixed by cotter pin 25 .in the flanges 14, 15 and extends through slots 21, 22 in the member 16 and through ay perforation 26 in the cam 23. The cam is provided with a suitable handle 27 and to allow the necessary amplitude of movement to the cam the back wall 28 of the sliding member 16 is cut away as indicated at 29 and the side of said member is grooved out, as indicated at 30. The cam 23 is adapted to bear against the back wall pplication led April 18,

4of the coupler,

28 of the member 16 and. against the surface 31 thereof defining the recess 2O at its forward side.

The sliding member 16 is applied in its opeiative'position vby .inserting the recessed end 32 through the opening 18 of the arm 13 so that the fiat surface 33 of the end 32 will slide along on the flat surface 34: of the side theinnerface35 held in sliding engagement with the surface 36 lof the coupler and the outer faces 37-87 ofthe lug 17 held in sliding engagement with the inner lface of the arm 13 so as to prevent any appreciable angular or lateral displacement of the Sliding member.

Operation lVhen connecting the couplers, the handles 27 of the rotary cams of both couplers, when both couplers are of the type shown, are turned toward the outer ends of the arms 13. Such movement of the cams mov-es the sliding members 16-16 outwardly 'toward the end of the arms 13-13 and thereby permits a preliminary engagement of the couplers to be effected by moving one toward the other sidewise. After the preliminary engagement is made the cams are rotated, as far as necessary, in the opposite direction to bring the gaskets 11-11 of the couplers into intimate contact. The curved 'surfaces of the lugs 12-12and that of the co-engaging lugs 19-19 are such as to automatically align the center of the couplers when one of vsaid. curved surfaces is forced against another, thereby ensuring that the coengaging faces of the gasket 11-11 will bear latwise against the other. The movement of the sliding member 16 is positive in both directions.

While I have described my invention in one specific embodiment, it is obvious that modifications in structure might be made lwithout departureL from the principle of the invention. Therefore I wish it to be understood that the invention is not to be considered as limited to the particular constructions, arrangement and devices shown and described except so -farfas the claims hereto appended are specifically so limited.
