T0 and whom it may concern.-

Be it known that I, SAMUEL M. BEERY, a citizen of the United States, residing at Chicago, 1n the county of Cook and State of Illinois, have lnvented a new and usefulImprovement 1n Hose-Couplers, of which the following is a specification.

My invention relates to improvement in hose-couplers of the class employed upon railway-trains for coupling together between cars the hose-extensions of steam and air pipes; and my ob ect is to provide a coupler of the class named of an improved construction adapting it more particularly, in the sense of mak ng it especially desirable, for use in connection with steam pipes.

In the couplers hitherto generally employed it has been usual to provide the coupler members wlth rubber gaskets, affording the meeting faces at the passage through the coupler, and 1t 1s found in practice that the heat of the steam has an injurious eflect upon the rubber requiring frequent renewal of the gaskets. Attempts have been made to overcome the dl fiiculty of employing rubber-gaskets by substituting therefor gaskets of an unyield- 1ng material which is not deleteriously affected by the heat of the steam, and rendering them yielding by means of confined springs, behind the gaskets in the coupler passage, which tend to force the meeting faces of the gaskets yieldingly together to afford steam tight joints and compensate for wear. The springs in the construction descrlbed being in the passage through the coup ler become heated by the steam to an extent which in time impairs their temper and consequently their utility. In my improved con struction I employ springs to press the meeting faces of the coupler members yieldingly together, which are so placed with relation to the steam passage as to be beyond the destructive influence of the heat.

It is further my object, to provide a coupler of the class named which shall be of a particularly durable and comparatively simple construction and in which the detachable parts may be quickly removed and replaced with new ones when desired.

In the drawings-Figure 1 is a broken view showing my improved coupler applied to hose-pipes, with the members in engagement;

Fig. 2, an enlarged view of one of the coup ler members; Fig. 3, a broken section taken on line 3 of Fig. 2, and viewed in the direction of the arrow; Fig. 4, a section taken on line 4 of Fig. 2, in the direction indicated; and Figs. 5 and 6 plan views respectively of opposite sides of the spring.

A is a coupler member comprising a head portion A, and the usual shank portion or nipple A I prefer to form the passage through the member as shown, whereby the fluid in passing through my complete coupler follows an S-shaped course without meeting with abrupt angles or obstructing surfaces, all of which would tend by increasing the friction to obstruct the free passage of the fluid. In the meeting surface 15 around the mouth of the passage is an annular socket 25'. Set into the socket is an annular gaskets, which may be of the form shown in cross section, and afford a meeting face 8 which should project, in practice, aboutone-sixteenth of an inch beyond the surface t. The gaskets may be of any suitable and preferably unyielding material which will not be deleteriously affected by the steam or heat thereof. The gasket is held removably but firmly in place by means of aclamping ring 0' having a lip 1" which engages a recess 15 at one side of the socket t. Atits opposite side the ring may be fastened in place with a screw r all in a known manner. On the head portion adjacent to the shank is a lug or projection q affording a socket q, the face g of which is substantially parallel with the surface t. At the outer end of the head is a lug or projection 19 provided at its outer end with a shoulder 1). At one end of the socket portionq is a pin or stop (1 Thus far described the coupler head is in its general construction like the standard coupler heads provided, with the exception that the usual shoulder at the edge of the surface q is aflorded by a spring B. The spring B is bent to present an attaching part it and a body-portion n, which describes substantially the arc of a circle, the center of which is at the center of the gasket 8. The spring is bent longitudinally to produce the shoulder 01 and has a curved bifurcated end n aflording a socket n. In the fastening end at is an opening n which registers with a threaded opening a tapped in the surface of theproection q. When in place the spring 13 extends at its part n against the surface at one end of the projection q where it is secured in position by means of screw m passing through the opening 11. into the threaded socket n Along its arm portion the spring extends across the surface g with the forks at its free end embracing opposite sides of the pin g whereby the latter extends in the socket n Between its ends the arm portion is out of contact with the surface 1 but bears at its end a against said surface. The shoulder n of the spring fills the place of the shoulder usually provided upon coupler members and cast integral with the projection q to engage the shoulders p of the other members. In attaching two of the coupler members together their meeting faces are brought into contact and the members are turned in the usual way to cause the shoulder 10 of each member to pass behind the spring shoulder 02 of the other member. The parts are so constructed with relation to each other that as the shoulders 10 pass across the springs B they compress the latter in the direction of the surface q The resilience of the springs which thus bear against the shoulders 19' at opposite sides of the gaskets press the meeting surfaces of the gaskets together and produce a steam tight joint. sufficient resilience to compensate for ordinary wear of the meeting faces 8 and will insure a tight joint even when the gaskets are worn down to the surfaces of the rings 0. Owing to their location the springs are comparatively far removed from the passage through the coupler, whereby the temper of The springs B have due wear of the shoulders will render the" coupler members useless. In my improved construction as the shoulders 19 bear against a yielding surface the wear upon them is very much reduced, and in the event that a shoulder n becomes worn, or a springB is injured or broken in use the spring may be readily taken off by removing the screw m and replaced with a new one. The spring is placed in position by simply passing it across the surface g until its socket 92 engages the pin g and then. fastened in position with the screw m asdescribed. Being held at one end by the screw m and at its opposite end by engagement with the pin (1 the spring is held firmly and durably in place.

What I claim as new, and desire to secure by Letters Patent, is

A hose-coupling member, having the socketprojectiou q, a projection p presenting a shoulder, and a stop g and a spring B bent to afford an attaching end n, at which it is secured to the projection q, curved resilient body-portion n, end 72 bent to bear against the surface of the projection q and recessed to engage the stop and a shoulder n on the body-portion of the spring between the lateral edges thereof, substantially as and for the purpose set forth.
