UNITED STA JOHN WARE, OF PINEVIlILLE, KENTUCKY.

CARF'PIPE COUPLER.

Application filed February 18, 1927. Serial No. 169,286.

This invention relates to a pipe coupling for railroad trains, the general object of the invention beingto provide automatic means for Coupling together the train pipes astwo cars are coupled together, so that it is not necessary for the trainmen to couple said pipes.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and. specifically pointed out in the appended claim. 7

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a fragmentary side view of a pair of cars showing the invention in use,

Figure 2 is a section on line 22 of Figure 1. r I

Figure 3 is a section on line 33 of Figure 1.

Figure 4 is a section on line 44: of Figure 1.

Figure 5 is an enlarged sectioned .view through one of the coupling means showing the pipes in section.

Figure 6 is a sectional view showing the valve means of two pipes in closed position and just before the parts assume a position where the valves will be opened.

As shown in these views, I place a depending bracket 1 on each end of each car in which is rotatably arranged a block 2 which has its trunnions 3 positioned so that the block can rotate about a vertical axis. Each block has an arm t which is connected with opposite sides of thebracket by the springs 5, these springs tending to hold the block in its middle position. A square shank 6 passes horizontally through the block and a coupling head 7 is carried on the outer end of each shank. A coil spring 8 is arranged between the head and the bracket and tends to hold the head and shank extended, but will permit the head and shank to move toward the center of the car when another head strikes the first head. Each head is of substantially conical form, with its base outermost so that a flaring socket is provided in the head which acts as a guide for the pipe of the other car when two cars are moving to coupling position. Each head 1s d1- vided in half, with thehalf 7 hingedly connected with the stationary partof the hinge 9, this hinge being a spring one, so thatthe part 7 norniallyremains in contacting relation to the stationary part. The hingepart 7 .has an opening 10 therein in which-is arranged a shouldered .member 11 which is normally held in its innermost position by the coil springs 12 on the bolts 13 which also act as guides for the member 11. A valve casing 14: is carried at the inner end of the socket of each head and this casing is connected by a pipe 15 which passes through the shank 6, with'the flexible pipe 16 which is connected with the train pipe. Each casing carries a valve 17 which is normally held upon its seat 18 by a spring 19, the outer end of the stem of the valve being beveled, as shown. An extension pipe 20 is connected with an extension of the casing by means ofa flexible tube 21, so that the extension pipe 20 is flexibly connected with the casing and the extremity of this extension 20 is also provided with a-valve casing 22 which carries a valve 23 which is a duplicate of the valve 17 and the stem of this valve 23 is also beveled so that when a valve in an extension 20 comes opposite a valve in the casing 14 of another car, the two valves will be opened so that fluid can pass from one car to the other. The parts are provided with suitable gaskets 24 to make a tight joint when the two parts come together. The casings are provided with rounded parts 25 so that as the rounded part on one casing engages the rounded part on the other, the casings will move apart and in this movement the hinge sections will be moved outwardly and then as the rounded parts pass each other, the spring hinges will force the sections closed and firmly pr-ess'a casing 22, against the casing 14 so that the valves will be opened.- The parts will be held in coupling positionby the shoulder on member 11 engaging the rear part of the casing 22.

From the foregoing, it will. be seen that I have provided means whereby train pipes. will be automatically coupled together when the cars are moved to coupling position and as soon asthe cars are uncoupled, the parts of the pipecoupling will automatically separate as the hinge sections will be raised by the pressure of the casing 22 on the shouldered member 11'to permit the extension pipe 20 of one coupling element to pass out of the coupling head of the other element.

IJI

It is thought from the foregoing description that the advantages and novel features of my invention Will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several I parts, provided that such changes fall Within the scope of the appended claim.

What I claim is A pipe coupling for cars comprising a head having a flaring mouth, said head being formed in sections, one section being hingedly connected with the other, a spring connected with the hinge, a spring pressed shouldered member carried by thehinge section, a valve casing in the head, a spring pressed valve controlling the outlet of the 'pipe of one car in the head'of another car;

In testimony whereof I aflixmy signature.

JOHN WARE.
