AUTOMATIC TRAIN-PIPECOUPLING.

SPECIFICATION forming part of Letters Patent N o. 619,401, dated February 14, 1899.

Application tiled October 17, 1898. Serial No. 693,764. (No model.)

To all whom it may concern/.-

Be it known that I, JOSEPH E. FoEsYTH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Automatic Train-Pipe Couplings, of which the following is a specification.

My present invention is primarily designed to aiford an improvement on the automatic train-pipe coupling set forth in my application, Serial No. 681,883, iiled May 27, 1898; and it relates to a simplification of the construction of the section in the train-pipe behind the coupling rendered telescopically yielding to permit the coupling, which is attached to the draw-bar, to follow the reciprocatory movements of the draw-bar under the influence of its spring.

Referring to the accompanying drawings, Figure l is a longitudinal broken section of a car with the train-pipe upon it for air, steam, or water and the coupling both shown in elevation and connected together by my improved device for the purpose; Fig. 2, a section taken at the line 2 on Fig. 1 and viewed in the direction of the arrow; Fig. 3, a section taken at the line 3 on Fig. l and viewed in the direction of the arrow; and Fig. 4, a section taken at the line 4 on Fig. 1 and viewed in the direction of the arrow.

A denotes the bottom of a car carrying the sills, one of which is presented at B, between which the draw-bar C, terminating in the draw-head C', is confined in the usual or any suitable manner.

E is the coupling for the train-pipe D, (airpipe, steam-pipe, or water-pipe.)

The coupling illustrated, which is suspended from the draw-bar and draw-head, as shown, involves the construction set forth in my aforesaid former application, lbut may be of any other construction suitable for use with it of my present improvement,which relates to means for connecting the coupling iiexibly with the pipe D. This pipe extends along the outer side of a sill B, being supported in hangers r r on the car-bottom, and the hanger fr near each end of the pipe on a car is of the loop shape shown in Fig. 4 to allow the end portions to yield in vertical direction Within the limits of their springy quality, for a purpose hereinafter explained.

At each end of the pipe D it is connected with the coupler E, as shown of the end presented to view in Fig. l, by means of my improved connecting means F, involving as its preferred construction the following: A socket 1o projects at a right angle from the end of the pipe D, which may be extended nearly to the end of the car. A plug o, preferably tapering, as shown, extends from one end of an elbow n, fastened at its opposite end to one extremity of a pipe-section m, the connection being that of a swing-joint to permit this pipe-section to turn or swing freely back and forth on the socket p. At the opposite extremity of the pipe-section m it carries a similar elbow n', terminating in a plug o', like the plug o, and fitting, like the latter, in a socket p', extending at a right angle from the rear end of the coupling E.

The connection F requires, of course, to be of suflcient length to reach from the plane of the pipe D (indicated at the dotted line a: in Fig. 3) to that of the coupler E, (indicated at in the same figura) and it thus occupies the oblique position in which it is shown, though it is quite'feasible to cause it to depend perpendicularly toward the coupler from a rightangled extension of the pipe D, a construction which is too obvious to require illustration.

As will be seen, the device F affords a comparatively inexpensive and very simple and easily-applicable flexible connecting medium between the train-pipe and the coupling, which yields to permit the coupling to yield correspondingly with the draw-bar under the reciprocatory movements to which it is subjected in use. Strain upon the connection and the coupler, which would ensue were the pipe D unyielding toward its end portion by the arc the lower end of the pipe-section m would then have to describe in being swung by the movements of the draw-bar behind and ahead of a perpendicular line from the end of the train-pipe, is avoided by the loose support r to the end portion of the pipe, whereby it may yield from its normal horizontal position under the swinging movements of the connection F. As will also be seen, my improved connecting device eec- IOO tually supplants the more cumbersome and expensive telescoping connection shown in my aforesaid application.

While the particular construction shown and described of my improved connecting device is believed to be the best for its purpose, I do not limit my invention thereto, since without departure from it the device and the manner of its connection may be variously modified by those skilled in the art.

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

l. In combination With a car, a train-pipe and an automatic coupling therefor suspended on the draw-bar, and a metal pipe-section extending obliquely from said pipe to said coupling and connecting them flexibly together, substantially as and for the purpose set forth. l

2. In combination with a car, a train-pipe and an automatic coupling therefor sus-V pended on the draw-bar, and a pipe-section extending obliquely between and having swing-joint connections at its opposite ends .respectively with said train-pipe and coupling, substantially as and for the purpose set forth.

3. In combination with a car, a train-pipe D terminating in a socketp, and an automatic coupling E therefor suspended on the drawbar and having a socket p at its rear end, and a pipe-section fm, terminating at its opposite ends in plugs o and o' rotatably confined, respectively, in the sockets 1J and p to connect said coupling yieldingly with said train-pipe, substantially as described.
