head is formed with a ball and socketjoint' 20 to permit comparatively free motionzin order to compensate for the movementiof the cars. It is held rigid by four springs 21, which through the medium of in and an emergency angle cock 24 which may be face, the air pipe opening through said 4 used for switching cars while the train l ne is changed. The train pipe is also connected with a T-connection 25 arranged to permit the ordinary hose connection to be made thereto, so that a car equipped with the coupler may be connected to one not so equipped. The train pipe in rear of the emergency angle cock is provided with a lateral portion 26 connected by swing joints 2? with the train proper and with that portion extending forward to the coupler. In advance of the lateral portion the train pipe is held under spring tension, through the medium of a spring 28 encircling the same and bearing at the inneraend against a hanger 29 dependent from the car body and at the forward end against the collar 30 carried by the train pipe proper. This insures a suiiicient tension on the trainpipe when the couplers are connected to maintain a tight connection.
The operation of the coupler will be apparent from the' drawing, it being understood that as the heads approach they will be guided into alining positions and the movement continued until the ends of the casings are engaged by the clamps 13 and the lever 15 operated to open the valves. ()n separation of the couplers the valve will be automatically closed in an obvious man- What is claimed is: 1. An automatic an" coupler comprising a coupling: head having an incl ned bearing face, a guide plate and clamp members carried by the head to receive and engage the opposing head,-a,va1ve in the air pipe, a
a lever for operating the valve and a dog car to close" the valve, a band carrying the dog,
said band being engaged by the leverin the coupling movement of the heads to open the valve. r
3. An automatic air coupler comprising a coupling head having an inclined bear ing face, the air pipe opening through said face, a guide plate and clamp members carried by the head to receive and engage the opposing head, a valve in the air pipe, a le ver for operating the valveand a dog carried by the head to engage the lever of the opposing head in the operation ofthe head to close the valve, a band carrying the dog, said band being engaged by the lever in the coupling movement of the heads to open the valve, said band and dog being spaced apart to permit the slight operating movement of the heads without affecting the dog.
4. An automatic air coupler comprising a coupling head having an inclined hearing face, the air pipe opening through said face, a guide plate and clamp members carried by the head to receive and engage the opposing head, a band carried by the guide Y CHARLES H. MONROE.
