=Richton, in the county of Perry and State of Mississippi, have invented a. newand useful Coupling for Air-Brake Systems, of which the following is a specification.

This invention relates to couplers for use in connection with the pipes of air brake systems and its object-,is to provide a device .of this character which is simple in constructionand the members of which are designed to automatically couple when the cars are coupled and to uncouple when the cars are se arated.

lurt her object is to provide a coupler of this type which utilizes all of the parts of an ordinary airbrake coupler, with the addition of certain parts designed to make the coupling and uncoupling operation automatic. a

With these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention has been shown In said drawings:-Figure 1 is a side elevation otthe coupled end portions of two cars and showing the present improvements applied thereto, the air pipe couplers being shown in engagement with each other. Fig. 2 is a plan view of the coupler shown in Fig. Fig. 3 is a view similar to Fig. 1 but showing the members of the coupler disconnected. Fig. 4 is an enlarged view partly in section and partly in elevation showing the automatic cut-off valve.

Referring to the figures by characters of reference A designates a car structure having hangers 1 depending from each end thereof, the hangers at each end constitut-v ing supports for a pipe 2 mounted to rotate therein. each of the pipes 2 and each of these rin s has a rod 4: secured to it and extending bachward therefrom, the rod being loosely mounted within the bottom portion of a hanger 5. A spring 6 is coiled about each of the rods and bears at its ends against the hanger 5 and the ring 3 respectivelysogas' to hold the hangers 1 normally in a predetermined position. A valve casing isseeured teens end Rings 3 are loosely mounted on of the pipe 2 and is connected, by means of .ordinary valve 9 located atthe end of the air pipe 10 mounted on the car structure A. A rod 11 is secured to the car structure and supports, at one end, a stem 12-which is secured to and moves with a valve 13 designed to swing within the casingi7 and to cut oft" pipe is'turned to a predetermined position.

A branch pipe 14 extends from the pipe 2 drawheads 'B of the car structures, this branch pipe being perpendicular to the pipe 2 and havinga short flexible hose 15 secured to it in any preferred mannera's by means serves as a connection between the branch pipe 14 and the coupler head 17 which is of the ordinary construction. The short section 15 of hose does not destroy, to an ob jectionable extent, the rigidity of the coupler head 17 relative to the pipe 2 but, at the same time, permits a slight flexing of the parts so as to allow for any up and down or side lations of the twocars when the parts are coupled.

That end of the pipe 2 farthest removed from the valve casing 7, is provided with an arm 18 extending forward from the end and rearwardly extending lever 19. A guide this lever projects through it and is designed to be limited in its movement thereby, it being understood that, when the parts are uncoupled, this lever 19 is free to swing forward against the outer end of the guide loop 20 and at the same time perlnit'the pipe 2 to partly rotate and to thus swing the coup tion shown in 3. Secured to theopposed car structure A and in the path of the lever 19, is an elongated loop 21 constituting means for setting the lever when the cars move toward each other, this setting of the lever causing the coupling member to move upwardly. Another loop 22 is secured-directly above the loop 21 and to the sanm structure, this upper loopb'ein-g so located'that when the lever 19 is forced upwardly icy-the loop 21, its-upper end will swing into the upper loop '22. .lt is of course to he understood that the adjoining communication with the pipe 2 when said at'the center thereof and directly. under the of'the car and merging into an upwardly a hose section 8 of flexible material, to the of a clamping band 16. The hose section 15 movement thereof due to the changing reloop 20 is secured to the car structure and.

ling member 17 downwardly into the posiends of the two meeting cars are provided with the same parts which have already been described, and Jthat both ends of a car are also similarly provided.

The normal positions of the levers 19 are at the outer ends of the loops 20 and resting thereagainst, the coupling member 17 being thus held downwardly extended as shown in Fig. 3. With the parts thus located, the valve 13 in each casing 7 is in closed position.

When two cars are brought together and while the draw heads thereof are coupling, each of the loops 21 pushes against the opposed lever 19 and swings it backward against its car structure A. The two pipes 2 will thus be simultaneously rotated so as to swing the coupler members 17 upwardly and as these members are located directly at the centers of the car ends, it will be apparent that they will be brought into engagementwith each other and will interlock as they are raised. Moreover the'rotation of the pipes 2 causes the valves 13 to open the pipes 2 and establish communication between them and the air pipes 10. As each lever 19 moves upwardly, its upper end passes into the loop 22 of the opposed car structure. It will be apparent therefore that the two members 17 of the air brake coupling will be brought together and locked simultaneously with the coupling of the drawheads B.

When the cars are uncoupled and move apart, the upper loops 22 pull upon the levers 19 and move them toward the outer ends of the guide loops 20. The pipes 2 are thus forcibly rotated so as to swing the coupling members 17 downwardly and disengage i them and as the pipes 2 thus rotate they are i closed by the valves 13. The parts are thus ready to be again coupled together when two cars are coupled and in the manner heretofore set forth.

By utilizing a coupler such as has been described it becomes unnecessary for the per son to reach between the cars for the purpose offastening the parts together. Attention is directed to the fact that the coupler members 17 and their connections 15 are located directly under the drawlieads B and are protected thereby from any injury by any objects which might fall over the ends of the cars. It will be further noted that the coupler which has been described utilizes all parts of the ordinary forms of air brake couplings, the same employing in addition thereto, the revoluble pipe 2, the lever 19,

the coupler member.
