AUTOMATIC PIPE-COUPLING.

The train-pipe and connections therefrom to the shoe of the automatic pipecoupling do not show in the right-hand part of Fig. 1, the view being taken at such an angle that these parts are located behind the coupling members.

Upon the end of the car shown at the right in Fig. 1 I have indicated in dotted lines the ordinary train-pipe 18, angle-cock 19, hose 20, and coupling 21, which may be readily coupled by hand with the coupling 17 of hose 16 in case one of the cars is not provided with an automatic pipe-coupling device.

My improved hanger 11, as shown more in detail in Figs. 2, 3, and 4., comprises a casting having an opening 10, in which the curved spring 9 of the half-section is supported, and also having a hollow cylindrical portion 22, in which the spring-buffer 23 is located. This buffer .23 is cup-shaped and has an arm 24-, which is pivoted at 25 in a hollow upward extension of the cylindrical portion 22. In the hollow cylindrical portion is located the volute spring 26, which extends into the cupshaped buffer 23, where it is provided with a cap 27, which bears against the inner wall of the buffer. The spring-bn [fer normally holds the curved spring 9 of the half-section against the forward part of the hanger in the opening 10, but at the same time allows same to yield during the act of coupling and to move about sufficiently to accommodate itself to the motion of the cars while running. The hangers are suspended by means of the brackets 28 from the car-couplers 29 and are secured to the brackets by bolts 30, which pass through the elongated holes or slots 31 in the upper part of the hanger. By this means the position of the hanger may be adjusted forward or backward, and in order to secure the hanger in position the face of the upper part or head 32 of the hanger, which is clamped against the bracket, is provided with a roughened surface, such as a series of grooves or corrugations 88, as shown more clearly in Fig. st. In this way the hanger is securely held against displacement. The half-section of the automatic pipe-coupling also has attached thereto a chain 35, which is suspended from the outer end of the arm 34, the arm being secured to the bracket 26.

It will thus be seen that my improved automatic pipe-coupling may be adjusted to any position and that the air-pipes of cars provided with my improvement may be automatically coupled and uncoupled, while at the same time if any one of the adjacent cars is not provided with an automatic pipe-coupling the pipes may be readily coupled by hand.

Having now fully described my invention,

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

1. In an automatic pipe-coupling device for cars, the combination with the half-section of the automatic coupling, of the trainpipe on the car, and an intermediate pipe connection adapted to be detached from the half-section of the automatic coupling and connected to the hose-coupling of an adjacent car.

2. In an automatic pipe-coupling device for cars, the combination with the half-section of the automatic coupling, of detachable means connected to the train-pipe and adapted to be connected either with the half-section of the automatic pipe-coupling of the same car or with the ordinary hose-coupling of an adjacent car.

3. An automatic pipe-coupling device for cars comprising, a half-section or shoe of the automatic coupling, and a detachable pipe connected at one end to the train-pipe and adapted to be connected at its other end either with the half-section of the automatic pipe-coupling of the same car or with the hosecoupling of an adjacent car.

4. An automatic pipe-coupling device for cars comprising, a yieldingly-supported halfsection or shoe, a short pipe-section connected to the shoe and provided with a hand-op-,

erated coupling member, a flexible pipe attached to the train-pipe of the car and having at its end a coupling whereby it may be coupled either with the pipe-section of the shoe or with a hose of an adjacent car.

5. In an automatic pipe-coupling device for cars, the combination with a half-section of the automatic pipecoupling suspended beneath the car-coupling, of a train-pipe on the car, and anintermediate detachable pipe connection adapted to couple the train-pipe either with the half-section of the automatic coupling of the car or with the hose-coupling of an adjacent car.

6. A hanger for an automatic train-pipecoupling device comprising, a casting having an opening therein, a cup-shaped buffet-having an arm pivoted in said opening and a vo- In testimony whereof I have hereunto set my hand.
