TRAIN-LINE COUPLING.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed December 14, 1910. Serial No. 597,336.

To all whom it may concern:

Be it known that I, JEAN BAPTISTE GENIN, a citizen of the United States, residing at St. Albans, in the State of Vermont, haveinvented new and useful Improvements in Train-Line Couplings, of which the following is a specification.

My invention which will be hereinafter fully set forth and claimed relates to antomatic couplings in the pipe lines for air and steam on railway cars.

The object of my invention is a valve and coupling for automatically connecting the adjacent ends of the pipe lines for air and steam on railway cars, so as to dispense with the use of flexible coupling devices for the signal, air brake and heating pipes. Also, to simplify the form of construction for the purpose described, so that the valves and other connecting parts may be readily removed and renewed and in order that a tight connection may be made between the adjacent ends of cars by a movable member of the valve so as to prevent the loss of steam or compressed air.

My invention is designed to be used with any ordinary form of supporting and guiding device, such, for instance, as is shown in the United States Patent, No. 862,068.

In the drawings is shown a. practical plan of embodiment of my invention in which- Figure 1 is an end elevation of a railway car showing the application of my invention. Fig. 2 is a side elevation of the same, and Fig. 3 is a longitudinal vertical section on a larger scale of the valve and adjacent part.

On a car, A, is shown a draw bar, B.

C is a spring secured to the draw bar B and carrying a rod, D, in such a manner as to give sufficient play to compensate for the inequalities and curvatures of the track over which the car travels. The rod D carries a plate, E, having guiding wings, e, which guide the couplings on adjacent ends of cars so that they register. The construction above described may be of an well known character and type, but pre erably as that indicated in the United States Patent, N 0. 862,068.

At the rear of the plate E and forming a part thereof, is a block or structure, E (usually a casting) formed in its front face with a series of recesses, 2, each of which terminates in a perforation, 3, and forming a shoulder, 4, between the recess and perforation, as shown in detail in Fig. 3; there being one recess and perforation for each line of piping.

Each perforation 3 holds a short pipe, F, having a screw-threaded end, f, projecting at the rear and a screw-threaded flange, f within the recess 2. This pipe is capable of having a sliding movement in the perforation 3, and has a coiled spring, F disposed upon it between the shoulder 4 and that formed by the flange f Upon the end f may be secured a bend or elbow, F or any other connecting piece with a line pipe, such as the signal pipe, F the air-brake pipe, F and the heating-pipe, F The movement of the pipe F in the perforation 3 is to accommodate the expansion and contraction of the line-pipe and the strain caused by the inequalities and curves of the track, with the spring F maintaining proper contact.

Upon the flange f is screwed a valve casing, G, having a spline, g, working in a groove, 5, formed in the recess 2 in the block E The object of this spline and groove is to prevent rotative movement of the casing when assembling the parts. This casing is constructed medially with an internal swell, g, on which is formed a spherical valve seat facing rearwardly and a spider, g, with a bearing for the valve stem. G is the valve disk fitting the valve seat and having a stem G which is carried inthe bearing of the spider 9 and projects beyond the valve casing and its extension and is provided with a head, 9

The front end of the casing G is formed with a socket, 6, somewhat conical and terminating in a concavely rounded seat. In this is inserted a cylindrical sleeve, H, with a spherically seated end fitted in the seat of the socket 6; said sleeve and socket in the casing forming practically a universal joint of limited range. The sleeve H is formed with a spider, h, which in its bearing carries one end of the valve stem G and be tween said spider and the head 9 is coiled a spring G. This spring keeps the sleeve H seated in its socket and the valve G upon its seat, while still allowing a certain amount of movement of the sleeve in its socket.

It will be noted that this construction V necessary flexibility of the wfin the cars pass around curves, ghtjoints are still maintained.

ice operates as follows: Two cars arebr 'ght together on the same track, the wing Yon one car engage the wings e on the op "osite car and the adjacent ends of the ve ve casing are directed together so that they rpgfster and so that the heads g of the valve stems meet. The springs Gr are compressed and the valve disks G leave their seats, permitting the medium contain'edj the pipe line to flow freely from one carto the other. When adjacent cars are uncoupled, the spring Gr becomes free and closes the valve and thus retains in the pipes of each car whatever medium they may contain.

I claim as my invention 1. In a train pipe coupling device, the combination of a structure having a series of perforated and shouldered recesses, a valve casing in one of the recesses, a connecting pipe in the perforation forming a shoulder with the valve casing, a spring coiled upon said pipe between the shoulders formed in the recess and the valve casing, a valve seat and spider formed within said casing, a valve disk fitting said valve seat and a stem held in said spider and carrying said valve disk and having a head projecting from the casing, substantially as set forth.

2. A train pipe coupling device comprising a member having a perforated shouldered and grooved recess, a flanged connecting pipe within said perforation and with its head in the recess, a valve casing disposed in said recess and connecting to said pipe and a spline on said casing disposed in the groove of the recess, substantially as set forth. 7

3. In a train pipe coupling device, the combination comprising a supporting memher, a valve casing carried by said supporting member, a valve disk and stem opening rearwardly in said valve casing and having the stem projecting beyond the front end and a deflectable sleeve carried in a socket within said valve casing and cooperating with said valve, substantially as set forth.

4.. In a train pipe coupling device, the combination of a valve casing having a spherical valve seat facin rearward, a valve disk fitting said seat, a efiectable sleeve in the end of the casing, a spider within said casing, a spider within said sleeve, a valve stem carried in said spiders and having a head projecting from said sleeve and a spring coiled upon said stem between its head and the spider in the sleeve and holdin the sleeve and the valve upon their seats, su stantially as set forth.

5. In a train pipe coupling device, the combination with a guiding device, a structure forming a portion of said guiding device and having formed therein a series of perforated and shouldered recesses, a valve casing in each recess having a valve seat, a valve disk fitting said seat, a valve stem carrying said valve disk and projecting beyond the valve, a defiectable sleeve in the end of the valve casing and spiders in the valve casing and sleeves supporting said valve stem, substantially as set forth.

6. In a train pipe coupling device, the combination of a valve casing having avalve seat, a valve disk in said casing. a defiectable sleeve at one end of the valve casing and means of maintaining the sleeve and valve normally seated, substantially as set forth.

In testimony whereof I affix my signature in presence of two subscribing witnesses.

JEAN B. GENIN.
