UNITED STATES PATENT rrrcn.l

RICHARD J. EDWARDS, OF GALENA, ILLINOIS.

PIPEacouPLING.

SPECIFICATION forming part of' Letters Patent No. 400,759, dated April 2,1889.v

Application filed October 23, 1888. Serial No. 288,957. (No model.)

To all whom'it may concern:

Be it known that I, RICHARD J. EDwARDs, a citizen of theV United States, residing at Galena, in the county. of J o Daviess and State of Illinois, have invented certain new and useful Improvements in Combined Car and Air-Brake Pipe-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings, in

which-- Figure 1 represents a side elevation. of the adjacent ends of two freight-cars coupled together according to my invention; Fig. 2, av

.of the valve in the air-brake pipe.

This invention has relation to that class of car-couplings covered by a patent issued to` mainly, toprovide such couplers with simple lforth.

and improved means, whereby the air-brake hose-couplings are uncoupled and the shut-off cock closed at the same time and by the same movement that operates the car-coupling devices, as will be more fully hereinafter set In the accompanying drawings, A A represent the adjacentends of two freight-cars;

vB, the usual or any improved draw-bars provided with the draw-heads C; D, the upper coupling-pins attached to the draw-heads by means of chains; E, the lower lcoupling-pins inserted in the lower pin-apertures in the draw-head'and supported by means of a pivoted operating-lever, F; G, the sliding dog in the draw-head, which is adapted to support the coupling-pin; H, the pivoted lever in a recess, in the draw-head adapted to operate the saidsliding dog.; I, the depending gravitating rod hung upon the said lever H and adapted to operate it, andfJ the transverse operating-shaft journaled in the beams of the car andprovided with a crank-arm, J', to

tions K operate the leVerF and operating-handles J at itsend at the sides ofthe car.

The parts are constructed and operated in substantially the same manner as in` my former, patent above mentioned, and a more minute description is deemed unnecessary in this specification. There are, however, la few important part-s which I will now point out. Inlthis device the sliding dog is not operated automatically to drop the pin, as in the former patent, but it is operated by hand, the lever H being placed back in a recess in thedrawhead out of the way, so that the couplingdink Awill not strike against it upon entering. I

prefer this construction'to that shown in my former patent, in that itv willV preclude the possibility ofthe lever H becoming broken orV injured in any way. In this invention I also place on the crank-arm J a loose anti-friction grooved roller, by means of which the lever F is elevated. This roller permits the lever to be elevated in a steadier and smoother manner, asis evident. I also provide the under side of the draw-head'with depending integral guards C', to preventthe pin E, rod I, and lever F from being injured in any way.

I will now describe the devices employed for detaching or uncoupling the hose-coup lings of the air-brakes.

' The letter K designates the main air-pipe of' the air-brakes provided with the usual Valves or stop-cocks, a, near the ends of the cars and connected to the flexible hose-sec- The stop-cock or valve a is operated by means of a lever, b, secured to the stem of the plug of the cock, this lever b being provided with a leaf-spring, c. When* this arm or lever b is in a horizontal position, as shown in Fig. 2, the passage is closed, and when turned down to the position shownA in Fig. 7 the passage through the air-pipe is open. This valve-arm b is turned up to close the valve by means of a crank-arm, cl, on the rock-shaft J, the arm d bearing against the v yielding spring c to prevent and reduce con-l rock-shaft that when the cars are uncoupled the arm will at the same time be turned up suiiiciently high to close the stop-cock or cutoff, thus preventing the escape of compressed air.

The ends of the flexible hose-sections K are provided with twin coupling devices L, provided with suitable interlocking flanged lugs.

I prefer to use in connection with my invention the Westinghouse detachable coupling, and I have shown that construction of device in my drawings. This hose-coupling is uncoupled by a partial revolution of its two sections, and for t-hat reason I prefer to use it. It is evident, however, that l may employ other detachable hose-couplings that uncouple in substantially the same manner without departing from the invention.

Secured on the outer faces or sides of the sections L ot' the hose-coupling by means of screw-bolts or cast integral therewith are upwardly and forwardly projecting' rigid arms L', which are connected by means of suitable chains, f, to crank-arms e on the rock-shafts J, as shown. The chains f pass over pulleys g, secured to the bottoms of the cars.

It will be observed that by drawing on either one of the chains j', by means of one of the rock-shafts and crank-arms, the coupling-sections L L will be elevated and rotated a sufficient distance to become disengaged from` each other, as shown in Fig. 2.

The crank-arms e are so located on the rockshafts that the hose-couplings may be detached by the same movement and at approximately the same time that the cars are uncoupled and stop-cock a closed. It will therefore be observed that by one partial revolution of one of the rock-shafts the whole operation o'f uncoupling is accomplished.

Among the many advantages derived from using my invention is that the whole operation of uncoupling the cars and air-brake` couplings and closing air-pipes may be accomplished without 'the slightest danger as well whenu the cars are in motion or standing` still.

It will be observed that I may use my invention with equal advantage for uncoupling steam-conveying pipes.

To uncouple the cars and shut the stopcocks a, the levers or handles J are moved forward, and to uncouple the hose-couplings they are moved in the reverse direction.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the cars, transverse crank-shafts journaled upon the cars, conducting-pipes upon the cars provided with flexible hose-sections, pipe-couplings on the ends of these lieXible sections, these couplings being provided with interlocking lugs and upwardly-extending arms, and chains connecting the upwardly-extending arms with the respective crank-shafts on the cars, whereby the couplings may be uncoupled, whether the cars be in motion or at rest, substantially as described.

2. The combination, with the cars provided with draw-bars and draw-heads, of the coupling devices, multiple crank-shafts journaled on the cars and adapted to operate the uncoupling devices, the air-pipes provided with the flexible sections, the pipe-couplings provided with interlocking lugs and arms, chains connecting these arms with the cranks on the respective crank-shafts, valves in the air-pipes, arms on the stems of these valves, these arms being adapted to be operated by cranks on the crank-shafts, whereby by a single movement of one of the crank-shafts the coupling devices may be uncoupled, the pipe-couplings uncoupled, and the valves in the air-pipes closed, substantially as described.

3. rlhe combination, with the cars, of the multiple crank-shafts journaled in the cars and provided with operating-handles, the airpipes provided with stop-cocks, arms on the stems of these cocks, these arms being adapted to be operated, by the cranks of the cranksl1afts,ilexible hose-sections on the ends of the air-pipes, coupling-sections on the ends of these ilexible sections, these coupling-sections being provided with interlocking lugs and rigid arms, and the chain for connecting these rigid arms with the respective crank-shafts, whereby the said stop-cocks maybe closed and the hose-sections detached at one operation, substantially as described.

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