COMBINED CAR AND AIR-BRAKE COUPLING.

SPECIFICATION forming part of Letters Patent No. 307,902, dated November 11, 1884.

(No model) T0 all whom it may concern:

Be it known that I, JOSEPH F. BA'rcHELoR, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Cornbined Car and Air-Brake Couplings, of whicl is accomplished will be described in connccl tion with the accompanying drawings, which illustrate what is deemed the best means of carrying the invention into effect.

Figure 1 is a side view, partly in section, of the ends of two cars with the improved couplers connected. Fig. 2 is a top view of two couplers separated. Fig. 3 is a front end view of brake-coupler. Fig. 4 is a longitudinalvertical section of the brakecoupler. Fig. 5 isa plan view of the valve.

The letter A designates the end of a car, and B the ordinary bui-'ters between the cars. rlhe draw-head O has the usual endwise movement by the operation of a slot, a, and a fixed bolt, I), passed through the slot. A spring, c, serves to keep the draw-head pressed endwise toward the end of the car.

The car-couplingE, in this instance, consists of the well-known hooks, which are pivotcd to the draw-head, and thereby have a lateral movement. Any other known suitable form ofcarcoupler may be used instead ofthe hooks. Springs to bear on the side of the hooks may be employed, as usual, to keep the couplerhooks engaged, and chains d and the usual levers (not shown) maybe employed to uncouple the hooks. These parts lare all well known. lhe car-coupler draw-head has a hollow front end, C, and a brake-coupling head, F, consisting of any suitable elastic material, like rubber, is fixed to a shank, e, which is adapted to slide endwise into the hollow front of the drawi' head.- A spring, f, within the hollow head keepsthebrake-couplingheadprojected. The elastic head F has a circular face, g, and a central hole, g', for the passage of the tluid, air, or steam, which operates the brake. Then the brake-coupling heads of two cars come in contact, the springs f will press them together tightly, but will yield to allow the elastic head F on each to set against the vouter front end, h, ofthe draw-head, as shown in Fig. l. As the heads are elastic, they will thus, together, and compressed between the draw-heads, produce an air-tight connection. The hollow drawhead has a passage, t', and a port, Z, and between thema valve, 7c. The valve consists of two circular plates, n, o1' one plate and a seat for it. The plates have two openings or ports, a, and one plate is fixed to a spindle, n, which is adapted to make a quarter-turn. lVhen the valve is open, the ports n in each plate coincide, and when closed the cut-offs n of one plate cover the ports ofthe other. The spin dle al projects through the top of the drawhead, and has an arm, at, attached. A spring, or", bears against the arm and keeps the Valve normally open. A lever, n, is pivoted to the car-platform, and projects above it, anda chain, nl, connects the lower end of the said lever and spindle-arm. By these or equivalent devices the valve may be closed at any time by aperson on the platform. rIhe usual brake-pipeG extends along below the bottom of the car to the brake-cylinder. (Not shown.) As the brake-pipe is immovable, a flexible hose, F, is used to connect the brake-coupling port Z on the draw-head with the said brake-pi pe, there` by providing for the endwise movement of the draw-head. From this description it will be seen that when the draw-couplers E on two cars are connected, the brake-couplers F will also be in Connection, as shown in Fig. 1, and said draw-couplers will keep the brake-couplers toget-her.

To insure that thebrakecoupler heads,when approaching each other in the operation of coupling up, will come together properly, so that their faces g will exactly coincide, I employ a curved or slanting guide-arm, I, which projects from one side at the front end of the draw-head. The operation of this projecting guide-arm to prevent lateral displacement will be understood by reference to Fig. 2. As each of two approaching draw-heads has a projecting guide-arm, I, on an opposite side, neither draw-head can deflect laterally. I also employ a groove, j, on the side of the draw-head opposite that whereon the guide-arm is attached. A portion of the groove has parallel sides p,- but near the front end of the draw-head the sides of the groove curve or spread apart, as at p', to form a Haring entrance. The guidearm of one drawzhead occupies the groove of the other. The upper and lower curved sides at the entrance of the groove serve to direct the arm I into the groove and prevent the draw-heads from deiiecting vertically. Thus by the guide-arms and grooves having curved sides or Haring entrance the brake-coupler heads are brought together properly.

In order to provide for connecting one of these brakecouplers with any style of V4brakecoupler now in use, a special port, q, is made. A yoke, 1', and screw s at the port serve either to stop the port or to connect therewith an ordinary hose-coupling. By this device a car with my couplers may be made up in a train with cars with a different coupler.

The couplers are designed for use with air, steam, or vacuum brakes, and may therefore be used with the Westinghouse automatic brake, for which it is adapted.

Having described my invention, I claim and desire to secure by Letters Patent ofthe United Statesl. The combination, substantially as set forth, of a draw-head, an elastic coupling for iiuidpressure brakes on the front end of the draw-head, a connection for the passage of duid between the said elastic coupling and the brake-pipe on the car, and a car-coupler to connect the draw-head with another drawhead, whereby when the cars are coupled the elastic coupling for the brakes will be compressed between the draw-heads.

2. The combination, substantially as set forth, of a hollow draw-head, a car-coupler attached to said draw-hcad, an elastic brakecoupling head on the front end of the drawhead, and a hole` in the elastic head, which is in communication with the brake-pipe on the car.

3. The combination, substantially as set forth, of a hollow draw-head, a car-coupler attached to said draw-head, a brake-coupling head having a shank adapted to slide into the hollow draw-head, and a spring to press the brake-coupling head outward.

4. The combination, substantially as set forth, of a draw-head, a brake-coupling attached thereto, a valve to open and close the passage in the said brake-coupling, and a 1ever on the car-platform, connected with the valve, whereby a person on the platform may at any time open or close the brake-valve.

5. The combination, substantially as set forth, of the draw-heads, a guide-arm attached at one side, and projecting in front of each draw-head, and a fluid-pressure brake-coupling, and also a car-coupler, both attached to a draw-head.

6. The combination, substantially as set forth, of a coupling for fluid-pressure brakes, and a head to which the coupling isattached, having at one side a guide-arm projecting in front and at the other side a groove for the reception of a guide-arm.

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