HOSE-COUPLING.

Specification of Letters Patent.

Patented July 13, 1920.

Original application filedl January 24, 1916, Serial No. 73,885. Divided and this application filed'April To all 'whom t may concern.'

Be it known that we, EDWARD A. RUSSELL and iii-mirra l. iluminan, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and-useful Improvements in Hose-Couplings of which the following is a specification.

Our invention relates to hose couplings, particularly to couplings for connecting the hoseV or equivalent elements in the steam train lines on railway cars.

The rinci Jal ob'ect of the 'nvention is P l l 1 to provide a hose coupling, of simple construction and of the straight port type, suitable for use in this connection, by means of which the coupling and uncoupling operations may be effected without the rocking movement of the coupler elements characteristic of vthe Sewall or gravity type of couplers, suoli rocking movements being objectionable because necessitating a bending of the hose, and also because, by rocking the coupler elements with the gaskets in contact, the engaging faces of the latter lare likely' to be crushed, frayed, or otherwise injured. i Y

A. further object of the invention is to provide a coupler so constructed that theV gaskets will be brought into close and accurate contact lwith each rother to provide a steam tight joint even when one or both' of the gaskets have shrunk or, for other reasons, are shorter than they are intended to be.

fr further object is to provide a coupling in which the gaskets` may be separated when desired lto permit the discharge of water of condensation from the train line without requiring the couplers themselves to be disconnected, one from lthe other.

A further object is to provide a coupler having the characteristics above noted, which can be mated with any of the standard gravity straight port couplers 'now in use on railroads, couplers of this class being all much alike but differing in certain respects'as to details of construction.

A further object is to provide a coupler adapted to be positively locked with the mating coupler element without the employment of any of the special locks'such as are now in use on many steam train pi po coui plers.

Serial No. 288,903.

The invention consists of the noveland improx-"ed constructions, arrangements and devices, to be hereinafter described and claimed, for carrying out the above stated objects, and suoli other objects as will appear from the following description.

This application is a division of our c0- pending application, Serial No. 73,885, filed January 24, 1916.

Our invention is illustrated in a certain preferred embodiment in the accompanying drawings, wherein i Figurel 1 is a side elevational view of a coupler embodyingour invention. l

Fig. 2 is an enlarged plan `view of the two coupler heads, showing them in the position they assume just before being brought into coupled relationship; and i Fig. 3 is a longitudinal sectional view taken along the line of Fig. 2. 1

Like vcharacters of reference designate like parts in the several ligures of the drawings. Y i

ris the two elements of the coupler are exactly alike, we will describe the left-hand element by the use of reference numerals, with the understanding that the corresponding parts of the other element are indicated on the drawing by corresponding numerals distinguished by the exponent letter Lca.

The -coupling member or head 10 is formed preferably with the usual projecting locking arm 11 provided with an undercut cam lug 12. On the other side of the coupling member is an undercut cam lug 13. These lugs, or as they may be called, gravity cams, engage with' the corresponding cam lugs on themating coupler arm 11a. Preferably-the coupling members are provided with means whereby they will be held in proper alinement before the gaskets are moved into contact with each other, and subsequently as against any tendency there may be for the members to rock 'on their cams when force is applied to the gasket holding or conduit members for the purpose of Vbringing the gaskets together. Vith these ends in view, the undercut groove 14 in the arm 11 is closed at the bottom as indicated at 14', forming a stop for the interlocking lug A13a of the mating coupler member. This prevents the coupling members from being rocked when the Vgaskets are pressed together so as to produce a gap between the gaskets at the top; such tendencyy ,beingl due tothe arrangement ol?L the locking Vlug centers below the axis ofthe gaskets. The lug 13 is -ormed on the top with a projection 13 and the arm 11a of the other coupler member is provided With a stud 15 which bears against this projection. f lhis arrangement prevents the weight '0f thswuplias members freni precludes a gap between the gaskets at the bottoml and holds the coupling members in alinement with each other before the gasketsare in @Oste-@1 The arrangement alsepermits the Complimenti?, Q1; either Coupling member with any stand-and coupler head O, thel gltwlty type @he `feessie for" ormingfthe lue With the ureiectiou inst-@edf Of placingthestiitl 1:5? leerer is t0 perm-it the con PhDs-1119: Q; `Ptlll?
