TRAIN-PIPE COUPLING.
class employed in con ling trainpipes be-,
tween railway-cars, an has for its principal object to provide a coupler in which the parts will be automatically connected when the cars are moved'together and automatically disconnected as the cars are separated, each of the coupling-sections being so constructed as to permit the necessary yielding when coupling at different heights or when the cars are on curves.
A further object of the invention is to pro' vide a yieldably-mounted coupling, so arranged as to hold the parts incoupled position Without frictional wear during the run ning of the train. 1
With these and-other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arran ement of parts hereinafter fully describe illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advanta es of the invention.
In t e accompanying drawings, Figure 1 is an elevation, partly in section, of a train-pi e coupling constructed in accordance with the invention. Fig. 2 is a sectional plan view of the same. Fig. 3 is atransverse sectional view on the line 3 3 of Fig. 2. Fig. 4 is a detail perspective view of one of the coupling members, a part of the yieldable coverin of the nozzle or male member being bro en away.
Similar characters of reference are employed to indicate corresponding parts throughout the several figures of the drawings.
To each of the cars, preferably at a point under the draw-head, is secured a bracket 10, the web of which has openings for the assage of securing-bolts 11. The bottom 0 the bracket is approximately cylindrical in form, and is provi ed with a circular openin for the reception of the circular shank 15 o the coupling member 16, and said shank is much- Specification of Letters Patent.

smaller in diameter than the opening inorder to permit free yielding when the couplers are connected at different levels and to ermit free play while, the cars are trav ing around curves. The cylindrical shank is provided with a pair of diametrically-opposed ongitudinal grooves 17 for the reception of threaded studs 18, which .maintain the shank in an approximately central position and at the same time limit its outward movement.v The shank is provided with an enlarged head 19, between which and the bracket is arranged a helical compression-spring 20, tending to thrust the coupling member outward to the position shownin Figs. 1 and 2. The head 19 has a threaded connection with the cylindrical body portion 21 of the coupling member, and in this bod portion there is formed an openin 22,- 'aving a tapered mouth to permit the ready introduction of the nozzle or male member 23 of an opposing coupling. The opening 22 is arranged at a point to one side of the longitudinal .aXisof the coupling, and on the opposite side of such axis isthe nozzle or ma e' member 23. This nozzle projects some distance beyond the body portion of thei 'coupler and has a tapered end portion to facilitate its entrance into the opening 22, and the outer surface of the nozzle is threaded or roughened and receives the sleeve 25, that is formed of rubber or other yieldable material, which when introduced into the opening 22 will form a practically air-tight joint.
Arranged within the coupling valve 27, that moves to c ose der the ressure of air and when the cars are uncoup ed prevents the escape of air through the opening 22; The nozzle when entered in this opening pushes the valve to the open position, as shown in 2.
The rear end of the s ank 15 is connected by a hose or flexible pipe 29 to the train-pipe A, a flexible connection being necessary in order to permitthe free yielding ofthe coupling members as the cars move together. The construction is such that the couplings will be automatically en aged as the cars are moved to ether, and when so engaged the sprin s wi 1 hold the parts connected without any ictional play between the nozzles and member is a position unconnections a; to permit coupling with cars which are not provided with the train-pipe coupling forming the subject oi the present invention.
I claim 1. In a train-pipe coupling, a bracket having a guiding-opening, a coupling member having a shank portion disposed within said guiding-opening, the shank having a pair of ongitudinal grooves, studs projecting inward from the bracket and entering said grooves, a spring tending to force the coup ling member outward from the bracket, and means for connecting the shank to the trainpipe.
2. In a train-pipe coupling, a hollow coupling member provided with an opening at one side of the center of its outer end, a nozzle,
and a yieldable covering for carried by and firmly secured to said nozzle.
In a trainpipe coupling, a hollow coupling memher having at its forward end a flared opening and provided with a projecting nozzle that opens within the coupling, and. a pressure-closed valve arranged within the coupling and adapted to close the passage through the nozzle and through said flared opening.
In testimony that I claim the foregoing as my own I have hereto a'llixed my signature in the presence of two witnesses.
