COMBINED AIR-BRAKE AND CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 482,382, dated September 13, 1892.

Application filed April 26, 1892.

.To all whom it may concern.-

Be it known that I, PHINEAS PELTON, a citizen of the United States of America, residing at Persia, in the county of Harrison and State of Iowa, have invented a new and useful Combined Automatic Air-Brake Hose- Goupling and Automatic Oar-Coupling, of which the following is a specification.

My object is, broadly, to combine suitable mechanism with an automatic ear-coupling whereby a continuity of passages suitable for conveying compressed air is automatically established between the air-conducting pipes secured beneath cars when the said cars are coupled together and the said air-passage is automatically closed, as required, to prevent the escape of compressed air when the cars are separated.

Another object of my invention is to produce an improved carcoupling especially adapted for use in connection with the said air-brake hose-coupling.

My invention consists, primarily, in the construction of a spring-actuated valvestem communicating with the air-conducting hose or pipe of the car to which it is attached and with an air-passage leading through the connecting-plates and in the means for normally holding the valve closed and automatically openingit when two cars are coupled together.

My invention consists, further, in the construction of the said connecting-plates and in the means employed whereby they may conform to the movements of the cars and inequalities in their surfaces, &c.

My invention consists, further, in the construction of the means employed for automatically turning the valve-stein, as required, to open the valve when the cars are coupled and to close the same when uncoupled.

My invention consists, further, in the forma tion and manner of connecting the car-coupling devices with the air-brake hose-coupling apparatus and in certain other minor details, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure l is a top or plan view of two complete couplers in engagement with each other, the one being attached toa car, parts of which are broken away to show the means for normally holding the couplers in proper position relative to each other. Fig. 2 is an enlarged Serial No. 480,665. (No model.)

transverse sectional View through the line 33 .r of Fig. 1. Fig. 3 is a side elevation of the parts shown in Fig. 1. Fig. 4. is a horizontal sectional view of one of the couplers. Fig. 5 is a perspective view of one of the connecting-plates. Fig. 6 is a perspective View of the valve-stem. Fig. 7 is a perspective view of a complete coupling device secured to a car, as required in practical use.

Referring to the accompanying drawings, the reference-letter A is used to designate the car.

A represents the draw-bar, secured to a car in a common way. Its outer end is divided longitudinally into two parts. The part designated by the symbol A projects forwardly beyond the other part and has an enlarged head. The forward end of this portion A is inclined forwardly and outwardly at A to engage a mating coupling and direct it into proper position relative thereto. A is a linkcavity formed therein, and Na pin intersecting the said link-cavity, as required, to adapt the device for use with a link-and-pin coupling.

Bis a formation on the outer side of the part A having a cavity 13 and a Wall E at right angles to the part A said wall having a downwardly and forwardly inclined front face for purposes hereinafter set forth.

The other portion of the forward end of the draw-bar is designated by the letter O and has a hook O pivoted therein and projecting forwardly therefrom. wardly and rearwardly inclined front face and This hook has a downis supported in an approximately-horizontal position, as required, to engage the wall B of a mating coupling and enter the opening B and thereby couple the cars together. 0 represents means for elevating the said hook, as

required, to uncouple.

D is a spring connected with the draw-bar and with a portion of the car to normally hold the coupler in such a position that the meeting faces of the parts A will engage each other and at the same time allow the requisite lateral motion.

Having thus described the car coupling mechanism, I shall now proceed with a description of the air-brake hose-coupling;

F represents the air-conducting pipe, secured beneath a car. F is a flexible hose-section connected therewith, having a coupling piece F secured to its end, and F is a mating coupling-piece screwed into the lower end of a vertical bore F extended through the part A H is an intersecting bore extending horizontally therefrom to the approximate central portion of the inner face of the part A.

11 1's a connecting-plate rectangular in form and placed in a cavity in the inner face of the part A It is secured therein by having a flange 1-1 formed on its ends to be extended under the flanges H formed or fixed to the part A One of these flanges H is preferably removable, as required, to provide for removalof the plate H J is a bore extended through the plate H and preferably larger at its outer end.

J is a spring-cushion having an opening in its center preferably formed of rubber and interposed between the plate H and the part A as required, to allow the said plate to conform to a mating plate and be held in close contact therewith. It will now be obvious that a continuity of air-passages is provided from the pipe F to theouter face of the plate H K represents a valve-stem placed in the said bore F and extending therein below the bore H. This valve-stem has a bore K extending from its lower end upwardly to the bore K which is in alignment with the bore H and adapted to communicate therewith when the valve is in proper position relative thereto and to be shut olf when the valve-stein is turned in the bore F N is a pawl actuated bythe spring N and secured to the top of the valve-stem K and normally extending forwardly, in which position the bore K will be shut oif from communication with the bore H. Its outer face is adapted to contact with the inclined forward face A of a mating coupling and be swung rearwardly, in which position the said bores will communicate and provide a continuity of air-conducting passages.

In Fig. 4 there is illustrated by dotted lines a fixed vertical jaw, as required, to adapt the device to be coupled with cars provided with a hinged vertical jaw.

In practical operation when two cars providedwith the coupling devices come together the hooks will reciprocally engage the walls B and thereby couple the cars, the pawls N will be moved rearwardly, as required, to open the valves of air-conductin g passages, and the plates II will remain in close contact with each other, as required, to produce an air-tight joint by reason of the pressure of the cushion J and the lateral pressure of the spring D.

I do not desire to be understood as limiting myself to the particular form of car-coupling used nor to location of the parts relative to each other; but
