CAR-CO UPLING.

SPECIFICATION forming part of Letters Patent No. 267,082, dated November 7, 1882.

Application filed July 11, 1882.

To all whom it may concern:

Be it known that I, JOHN R. HOWARD, a citizen of the United States, residing in Sour, erville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Self-Acting Elastic (Jar-Coupler, (and tomy knowledge and belief the same has never been in use,) of which the following is a specification.

The object of my invention is to self-couple ,cars of various heights and on the sharpest curves, and have them disconnectfrom the sides of the car by a fly-back frictionless lever disconnection; also, to have them disconnectfrom the top of the car by a lever that works conjointly with or independent of the fly-back lever disconnection; also, to have the whole train elastic when coupled together, so as to avoid that sudden jerk which is caused by starting and stopping; also, to have a double fastening to do away with all danger of the train breaking apart while in motion. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an inverted plan of the machine; Fig. 2, an inverted elevation of the machine. Fig. 3-a sectional viewalso represents the machinecoupled, and shows in detail the mechanism of the difterentconnections of the coupler-head. Fig. 4: is a section of the line It in Fig.3, and shows a view in detail of the fastenings. Fig. 5 is a cross-section of Fig.4; Fig. 6, an end view, and shows the mechanism for disconnecting from the top of the car.

Similar letters refer to similar parts throughout the several views.

The wooden sills A A-and the iron crossheads B B constitute the frame-work of the machine. Through these cross-heads the shaft 0 moves back and forth. On this shaft, between the cross-heads, are two heavy spiral springs, separated by a band or collar that is keyed to the shaft. The neck of the shalt has an angulated hole in it and a band or collar the same distance from the cross-head as the shaft is to move back. The rear end of shaft has a washer or collar keyed on it a like distance fromthe rear cross-head, to allow for the advance. On the band which forms the shoulder on shaft G and on the band which separates the spiral springs areartns extending per- (No model.

pendicularly. Through the endof these arms the small shaft S moves back and forth. ()n this shaft, between the arms, are confined two spiral springs, separated by a band keyed to the shaft. The tension on these springs is such as to reduce the heft of coupler-head 1) (when connected with shaft S)to the minimum. The shaft 0 connects with the coupler-head l) by a bolt and makes a joint that gives vertical and lateral motion. The coupling-screw E conmeets with the shaft S, with a welded eye; the

swivel end bolts to the center, on the top side of coupler-head D,close to outer rim. By manipulating this screw the coupler-head is kept adjusted, all of which is shown in detail in Fig. 3.

Thecoupler-head D is a hollow casting, which has an aperture sufficient to receive atthe same time the opposite end of fastening-bar F, (see Fig. 5,) which bar has a projecting and hookshaped end. It also has legs which slide into grooves in the coupler-head. Between these legs the pawl G is attached by a bolt passing through coupler-head D, the legs of fasteningbar F,and the pawl. On the back of this pawl is an extension, which hinges to the rod H, which rod has a spiral spring on it. The end of rod goes out through a hole in the side of coupler-head D, all of which is shown in detail in Fig. 4.

To the rod Hthe lever I connects and ships into a standard, and on the end of said lever is hooked a looped connection, which moves in a slide-plate that is fastened to the under side of coupler-head 1). Through this looped connection the lever-bar J rests free and clear. Said lever works on a pivot on the plate K and rod L, which rod runs from the lever M, over the sills A A, down to lever N. There is another rod that runs from lever M, under the sills A A,to lever N, which has the spiralspring Q, confined on it close beside the sill A. There is a piece of the rod L left out from sill A to lever N, so as to show the under rod and the spiral spring 0, as seen in Fig. 1. These pawls G G are operated to disconnect the couplerheads by pulling either of the levers M or N outward from either side of the car. 0n letting go the handle it immediately flies back, so the lever-bar J will play clear in the looped connection, and the pawl G in coupler-head D is ready to fasten. The eyes on the handles by said shackle.

on lever Mand N are for the purpose of receiving hooks on the outer edge of car, so as to hold the levers there andprevent the cars from coupling when necessary.

The device which holds coupler-head D in the center of car has a wrought-iron bed-piece with lugs, through which a bar, 1?, with a spiral spring, P, secured thereto between the lugs, moves laterally. On the end of bar next to coupler-head D is a roller, and to keep this roller perpendicular there is a short pin in the rear lug-hole, which fits into a groove on the top side of the bar, which prevents it from turning.

The yoke W, which goes around couplerhead D and fastens to the buuterU, is of round bar-iron. The back of coupler-head D rests hard against it, as shown in Fig. 2. There is room on the other side for the coupler-head D to spring over when rounding the sharpest curves. It is also deep enough to allow the coupler-head D to depress or elevate, for in coupling cars by this method it is necessary for one coupler-head to depress one-half of the difference and the other elevate one-half, so the fastening-bars F F will enter straight their respective sockets in coupler-heads D D.

The mechanism for disconnecting from the top of the car consists of a chain, a guarded swivel-pulley, rod, and lever. The chain is shackled to rod H. (See Fig. 6.) The leverbar I is connected at the same time to said rod The chain then goes around the guarded pulley, care being taken to have the chain slack enough for the movement of coupler-head D. It then connects with a rod flush with the under side of the cross-beam of the car. Saidrod goes through a hole in the cross-beam to the platform, where it connects with the lever, the endof which is hinged to the platform. The handle rests between the ears on a short standard. By raising the bandle of this lever the fastening disconnects. If it is a box-car, the rod must be lengthened, so the lever will be at the top of the car. This lever works conjointly with or independent of the fly-back disconnection. On Fig. 6 a part of the yoke W is broken out to show the connectionsof the levers which operate the pawl G.

To connectthis coupler-head with the oldstyle link and pin it is necessary to remove the bolt that secures the fastening-bar F to coupler-head D and detach said bar. Then replace the bolt through two short pieces of pipe, to take the place of the legs of bar removed to keep the pawl Gin its proper place. Then push the hook-shaped end of the bar into the funnel-shaped socket in coupler-head D, so it will fasten. The legs of the bar will then project outward. The ends of said legs are of sutficient size to admit of a hole large enough 1 for a pin of sufficient strength to pass perpendicularly through said legs, so the old-style link can be-connected between said legs by said pin.

Having fully described my invention, what I desire to claim and secure by Letters Patentis- 1. In a car-coupling, the coupler-head D, provided with a funnel-shaped socket and the pointed hook-shaped fastening-bar F, rigidly secured thereto, substantially as described.
