To all whom it may concern: f v stock which it is desired to automatically Beitknown that I, GEORGE D.

Rigidly secured on the lower end heads at the ends of the car or other rollingof said standard is the resilient push-rod D,

which passes through a tubular stem D rigidly connected with the bar 0', and in which are provided coiled springs, as shown more clearly in Fig. 4, one of which engages above said resilient push-rod D and the other of which engages on the under side thereof. Said springs and the resiliency of said rod act when the coupler is forced rearwardly, thrown out of a perpendicular, or deflected laterally to return the same immediately to alinement. Rigidly secured on the standard D above the oscillator-case is the cross-head E, at the ends of which are secured, integrally if preferred, the forwardly-projecting parallel rods E E. On the outer ends of said rods, respectively, are the conical heads e and the funnel-shaped sockets e, as shown in Fig. 2. Said conical heads and the socketed heads 9 are complemental and are adapted to engage each with the complemental part of the coupler carried on the car with which the coupling is to be made, as shown in Figs. 1 and 2. The trainpipes F, G, and II' are adjustably engaged and supported in said standard D, as shown, one below and two above the oscillator-casing and passing through apertured enlargements on the standard D and firmly secured therein in an adjusted position by means of set-screws Said pipes are provided on their inner ends with couplings f g 72, adapted to secure thereto the usual hose-pipes f 9 ]L2, and at the outer ends with heads or fittings f g 71 Each of said heads is provided on its front face at its bottom and sides with inwardly-turned fiaugesf to engage the gasket f, in which is provided a bottom and lateral grooves, as shown in Figs. 6 and 7, to secure said flanges. Said flange f is emitted at top of said head to permit the gasket to he slipped readily into position or to be removed therefrom. Adjacent to the outer end of each of said pipes is provided a stay of metal I, provided with clips, which engage around the pipes F, G, and H and serve to rigidly connect the same near the heads and act to hold the same in uuvarying relation.

The operation is as follows: The casing C is adapted to reciprocate backwardly and forwardly on the guides, while the plate C is adapted to oscillate through a considerable are on the ridge or edge 0. When two cars equipped with devices embodying my invention are brought together in coupling relation, when the draw-heads come into position to engage the conical heads on one of the automatic couplers engages in the complemental socket-heads of the other, thereby directing the ends of the train-pipes into register as the draw-head is coupled. The air and steam pipes when forced into alinement by the interaction of the conical head and said socketheads are not only brought into exact register thereby, as shown in Figs. 1, 2, and 4, but the adjustment of said pipes is such that when in coupled position'said pipes and the oscillator-casing of each coupler are forced rearwardly against the tension of the spring b b on the thrust-rods, which are of suflicient be Varied without departing from the principles of my invention.
