To al?, whom, t may concern:

Be it known that I, SHERMAN NV. DAY, of Avonmore, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Hose- Oouplings, of which t-he following is a full, clear, and exact description.

This invention relates to couplings for hose or a series of hose on railway-cars and the like, and the object is to provide a simple device that will be automatic both in coupling and uncoupling, so that the same will require no personal attention when cars are coupled together or separated.

rlhe coupling may be attached by bolts or otherwise to the draw-head of the car-coupling, or it may be attached to the sill or framework of a car at one side of the drawhead. In either event the hose coupling should be slightly forward of the car-coupling, so as to insure a close connection when cars are brought together. p

The invention consists in the construction and novel arrangement of parts, as will be hereinafter specified, and particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of two couplingsections embodying my invention and showing the same separated. Fig. 2 is a plan View of the same on an enlarged scale and showing the sections as connected, and Fig. 3 is a partial elevation and partial section on the line 3 3 of Eig. 2.

Referring to the drawings, Adesignates the coupling draw-head, of box-like or hollow construction and having the hollow shank portion A', designed to ,be slidably attached to a car-coupler draw-head or other support, and a buffer-spring a is designed to give a yielding motion to the coupling-section when two sections are brought together in the actV of coupling cars. I Y

One side of the coupling-section is closed by a rigid wall a', which is transversely rounded or curved at the forward end a2, and the opposite side is closed by a yielding wall a3, which has Walls a4 respectively connected with its top and bottom edges and projected about half-way across the coupling-head. A plate a5 is rigid with and extends from the rear end of the wall a3, and screw-bolts a6 pass through holes in this plate and engage in tapped holes in the portion A of the coupling. A rubber or similar yielding cushion a7 is placed between the plate a5 and the outer side of the portion Al; and the outer end of the yielding wall or section is preferably flared outward or bell-mouthed, as shown, to facilitate. the entrance of the rigid side wall of an approaching sect-ion. The inner end wall of the yielding section is transversely curved, as at as, to correspond with the curve of the end a2, so that when these parts come together there will be a cam-like action to force and hold the coupling-blocks B closely together. By this construction a projecting tongue is formed by the wall d and its end a2.

It will be seen that when two coupling-sections are in coupling position the aforesaid tongue of one section will enter the space between the yielding wall and the adjacent side of the other section, and the edges of the top and bottom walls a4 of the two sections will meet, thus providing a closure to protect the interior parts from rain, snow, or the like.

B designates a rocking valve-block having trunnion-bearings in the coupling-head A, and having a port or a number of ports b extended through it. The inner ends of the ports b have nipple projections b', from which iiexible hose connections b2 extend to valves B', which communicate with the trainpipes B2. l have here shown three valves B for controlling a like number of train-pipes, but it is to be understood that a greater or less number may be used without departing from the spirit of my invention. Y

A valve-stein b3, common to the plugs of all the valves, extends outward through the top wall of the portion A of the coupling-head, and a crank-arm h4 on said valve-stem has a link connection b5 with a crank-arm h6 on an extended trunnion of the valve-block B, so that the several valves willbe closed or opened by the movements of the valve-block.

The outer or contacting face of the valveblock B is provided with a gasket t7, of yield- IOO ing material, so that when two blocks are engaged the contact will be practically air and water tight, and the rear edge of the block is provided with a stop-fiange bs to prevent the forward slipping of one block relatively to the other.

As a means to hold the two coupling-heads together I provide a rib or projection b on the rigid wall of one head to be engaged by a corresponding depression 7110 in the yielding wall of the other head, and to automatically rock the valve-block to close the valves as the two coupling-sections are separated I employ a spring bu, attached at one end to the block and at the other end to the head.

In operation upon bringing two cars together the valve-block of one coupling-head will engage with the block of the approaching coupling-head, and the two blocks will be rocked to the position shown in Fig. 2, and the ports of one block will register with the ports of the other block, and at the same time thel several valves will be opened, thus allowing the passage of the elements in the pipes from one car to the other. Then the cars are separated, the springs Z111 will rock the blocks to the position shown in Fig. 1, thus closing the valves.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A hose-coupling comprising a head, a rocking valve-bloek therein having a port, a valve carried by the head, a connection between said port and the Valve, and a connection between the block and valve whereby said valve may be open ed and closed by the movements of the block, substantially as specified.

i. A hose-coupling comprising a head, a yielding side portion therein, a rocking valveblock in the head and having a port, a valve, a flexible hose connection between the port in the block and the valve, and means for controlling the Valve by the rocking of the Valve-block, substantially as specified.

3. In a hose-coupling, the com bination with a head, of a rocking valve-block with which the hose communicates, a Valve commanding the hose, and an operati Ve connection between the Valve-block and the Valve, substantially as described.

4. In a hose-coupling, a head having a hose terminal carried by the head, a spring-wall at one side of the hose terminal, the wall being vertically extended and having top and bottom edge flanges, the flanges being extended approximately to the center oi' the head, and a tongue rigid with the head and carried opposite the yielding wall, the tongue bcingeapable of passing inward of the springwall of a companion head and the springwall being capable of pressing and holding atongue inward against the head, substantially as described.

5. In a hose-conpling, a head having means for connection with a companion, a valve block rockably mounted in the head and having a port therein, a valveblock having a plane side capable of hermetic connection with the corresponding side of the companion block, and a hose communicating with the port, substantially as described.
