AUTOMATIC TRAI N-PIPE COUPLING.

TQ all whom t may concern.'

Be it known that I, FRANK H. RUTHER- FORD, a citizen of the United States, and a resident of Chicago, in the county of Cook 4views of details of my invention.

and State of Illinois, have invented certain new and useful Improvements in Automatic Train-Pipe Couplers, of which the following is a clear, full, and exact description.

My invention relates to automatic trainpipe couplers', and its object, in addition to automatically engaging the coupler and establishing a perfect communication with the pipe system of the other cars of the trains connected therewith and adapt itself to any angle required by the exigencies of the train and cars thereof, is to enable it to move with the car-coupler and its draw-bar, and thereby avoid the necessity of providing automatic adjustment for it in orderto accommodate itself to the movements of said carcoupler; and its object is also to greatly reduce the length of the automatic coupler and to reduce to a minimum the wear of the coupler and its support. ,Y

In the drawings, Figure l is a side elevation of the ends of two connected cars having my improved automatic cou'f` 1ers applied thereto. Fig. 2 is a longitudinal central section through one of said couplers detached froml the car. Fig. 3 is a section of the body ofthe coupler, taken on dotted line 3 3, Fig. 2, and drawn to a larger scale. Fig. 4 is a plan view of the under side of the end of the carrier of a car having my in iprovements applied thereto, with the automatic coupler shown in dotted lines. Figs. 5 and 6 are Fig. 7 is a side elevation of a modified form of my improvement.

Referring to the drawings, A represents the end of the car to which my improvements are applied. B represents the center sills thereof, and C the car-coupler and its draw-bar.

The car-cou',r ler may be of any desired design, and the, rigging for securing the'drawbar of said coupler to the car may be constructed in any suitable manner, so long as it yields to and modifies the sudden strains and concussions to which the car-coupler is subject.`

My improvements comprise an automatic train-pipe coupler, a carrier therefor, and,

means for detachably connecting said carrier to the draw-bar in such manner that the said carrier will move bodily with the draw-bar under normal conditions, but will bodily wrench loose therefrom without injury to itself or the train-pipe coupler carried thereby should the car-coupler and its draw-bar be torn from the car.

The carrier D of my invention consists of a longitudinally-disposed bar which is prefer-l ably less in length but about the same width as and is placed parallel with and under the draw-bar. Its forward end is bent downward to form a hanger d, the lower end of which is formed into a ring or annults E, through the opening in which the train-pipe coupler extends, as will hereinafter be more fully explained. The carrier is secured to the coupler by means of a bolt depending down from the bottom of the draw-bar near its head, which bolt e extends into a slot f, made longitudinally in the bend of the carrier. rIhe portion of the slot in the bend of the hanger has its lower part made wider, so that when assembling the equipment the head of the bolt may be passed therethrough and its shoulders catch under -and supportv the forward end of the carrier. The rear end of the carrier is preferably made narrower and bent upward and then forward to form a hook G, the upper horizontal portion of the bend of which is adapted to enter the eye of a suitable staple g, secured yto and depending from the underside of the draw-bar near its lower end. p

At about the bend of the hook Gr carrier D is provided with transversely-projecting arms h h, which extend past andif desired, may

ride upon the longitr.dinally-disposed horizontal guide-rails H H, which are parallel to each other and have their upturned extremities secured to the under side of the center sills of the car. Should the cotpler be torn from its moorings, the carrier D world` move with the draw-baruntil the bolt e prlls out of slotf and the staple g would move away from hook G. When this happens, the forward end of the carrier and the automatic cor pler F would fall; but I limit the extent of this fall by means of a chain I, one end of which is secured to the forward end of guide-rails H and the other end to a suitable eye y', secured to and projecting up from the forward end of said coupler F, as shown. I also relieve the strain on this chain, when the draw-b ar is torn from its moorings, by a ch ain J that limits the forward `movement of said coi pler. One end of this chain J is secr red to an eye K, secured to the bottom of the car a suitable distance to the rear of the draw-bar, and the ICS other end of which is secured to an eye llc, projecting rearwardly from the bend of the hook G of said carrier.

The automatic coupler F is constructed substantially the same as that illustrated and described in the application for Letters Patent of the United States filed by me June 13, 1906, Serial No. 321,547, except that the rear end of the cylindrical extension 4 of the body extends back of the anni-.lus and provided with a partly-closed end 2 and is provided with a circumferential flange 3, which is adapted to bear against the rear surface of the ann'ilus E. The horizontal position of the coupler is maintained by means of a comparatively heavy helical spring 5, the smallest spiral of which is seated in a circular groove 6 in the rear of end 2 and the largest spiral of which has its end 7 extended to the center thereof and then extended axially to and through an opening 8 in the center of head 2, where its extremity is formed into an eye and linked or articulated with an eye 9, extending through opening 8 from the center of a pivotal head 10. head 10 consists of a circular plate which is-passed up through a l longitudinal slot in the bottom of the cylindrical extension 4 of the coupler and fits l within and is adapted to have edgewise contact with the inner circumference of said cylindrical extension. This head is provided with a screw-threaded shank 13, that passes through a suitable tapped opening in the lowermost segment of annulus E and has a nut 14 on its lower extended end, by tightening which said head can be readily securedin position in the same transverse plane as the annulus and at right angles to the axis of the coupler when the latter is in its normal position.

The helical spring 5 is an expansion-spring, and the pressure which its smallest spiral exerts against the head 2 normally keeps said head bearing against the annulus E sufficient to keep the coupler in a horizontal position, substantially as shown in Fig. 2 o'l' the drawings. In order to prevent the wearing away of the contacting surfaces of the pivotal head 10 and the cylindrical extension 4 of the coupler, I face the inner circumference of said extension with steel 15, and l. provide-a steel rim'16 for the circumferential edge of the head 10. The edges of said pivotal head are rounded, and the inner circumference of the annulus is likewise rounded, so as not to interfere with the movement of the coupler to any angle which its engagement with other train-pipe couplers may require.

In Fig. 9 I show a modified form of my invention, in which the principal difference is in the omission of guide-rails H and the substitution therefor of hooks M. The latter are secured to and depend down from the center sills near the end of the car on each side of the car-coupler and-in such position that whenI the automatic couplers have been carried by the draw-bar of the coupler suiiiciently forward toward the adjacent end of the car to a point beyond which it would be dangerous for them to go arms h 7L will catch against said hooks and when the automatic coupler is freed from the car-coupler will fall into and catch in said hooks.
