l/Vestinghouse or other coupler terminal of the proper train pipe. This provides for revolution of the section carrying the coupler as distinguished from rotation of the tube within the head and gives revolution about the joint and in a plane instead of the conical path of movement which is caused by swinging a diagonally placed coupler about the end of the pipe.

My illustration is intended to be conventional in that the head, tube, supporting mechanism pipe joint and coupler parts shown are selected from among various such parts capable of use with my invention and that the individual types of this mechanism shown need not be used to practice my invention.

In Figure l the head 10 is secured by bolts 11 to a yoke 12 which straddles a block 13 at the lower end of the bracket 14 carried by any fixed car part 15. The rear 16 of the yoke is adapted to be pressed against the back face 17 of the block 13 by a spring 18 held to its duty against the rear face of the yoke by a bolt 19. This bolt is secured within the block 13 at one end and carries a nut 20 and washer 21. This general form as so far described is shown in a copendingapplicat on filed by Edward A. Robinson for connecter for train pipes Serial Number 412,645, filed September 25, 1920, and is one only of many constructions with which my invention may be used. n

As in the Robinson application, the head is shown as having forwardly spring-pressed connecter tubes 22 which carry gaskets at their forward ends at 23;. and which, are pressed forwardly within recesses 24: by springs 25 abutting against collars 26. The tension and extent of normal projection may be adjusted by nuts 27 with any desired locking mechanism for them. I

In the Robinson construction each tube is free to turn about its axis and the pipe coupler parts connect with the head and swing with the tube about the axis of the tube. lVith the relatively low pressure of these springs 25 this is entirely feasible when the connecters are not united to the connecters on other cars, but with additional spring pressure the turning of such a tube becomes This is so far true that in one construction. where a tube through the head is subjected to the axial pressure of the main connecter spring, it was found impracticable to make it turn in the head.

However, the rotation of the tube for the purpose of swinging the couplers for the pipes about the tube axis presents the two difiicul ties that the tube cannot be turned while the pipe is under pressure from connection with another car and that the parts carried by it swing through the path corresponding to the surface of a cone twisting the coupler at the same time that it revolves about the tube.

With my construction I avoid rotation of the tube and even accidental swinging of the parts carried by it about any axis of the tube by preventing rotation of the tube.

One method of preventing the rotation of the tube is shown in Figures 3 and 4 where it will be seen that a key 28 is fitted into the head 10 and is splined into the tube so as to allow longitudinal play of the tube while preventing rotation.

In Figure 5 another means of preventing tube rotation is shown as applied to the middle tube. in it the head 10 is mounted upon a resiliently held tubular support 29 keyhole-slotted at 30 so that the angularlyextending fitting 31 and other parts can be inserted for assemblage but cannot swing with the tube. The tube is here screwed into the fitting by a spanner wrench.

I insert a joint conventionally shown at 32 between the part 33 connected more directly to the tube and the part 34 rigidly connected to the half coupler 35 interiitting with the half coupler 36 carried by the train pipe hose 3?. I

By this construction the rigid section 38 swings about the joint in a diagonal plane which is always the same and which may be selected to bring the two half couplers together to the best advantage without requiring torsion of the train pipe.

Two forms of joint are shown in Figures 7 and 8. In Figure 7 the parts 33 34 are duplicates except for the bolt-receiving construction and that one carries a ring 39 and the other a groove #10. Packing 41 assists in forming the seal.

T he spring bolt 42 is secured to one of the parts at one end, is coiled at 13 to. give it longitudinal spring and passes through the other part to a "nut 44 resting upon packing 45. A cap l6 covers the nut and packing and may itself be fluid-tight.

In the other joint the parts 33 34 meet in opposing flanges a7, 48, spaced by packing a9. One of the flanges is threaded to receive a cap 50 which engages the other flange also to draw the flanges together.

It will be evident that various changes may be made by others interested in obtaining part or all of the advantage of my invention without copying it and it is my purpose to include herein all such changes as come within the reasonable spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1.
