CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 349,726, dated September 28, 1886.

Application filed December 11, 1885. Serial No. 185.395. (No model.)

the coupler to be readily detached on any grade, and thus enable the train to be cut in two when moving on upgrade or making a flying switch without necessitatinga slackening of speed.

A further object is to provide detaching and automatic coupling devices that shall be simple and durable in construction, of small initial cost, and adapted to be applied or combined with draw-heads, so that they may be used in connection with cars furnished with the ordinary links.

With these ends inview my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view of the draw-heads of 'two adjacent cars provided with my improved coupling. Fig. 2 is an end view of one of the couplings, partly in section. Fig. 3 is a longitudinal section of the two couplings when connected. Fig. 4 is a perspective view of one of the couplings, and Fig. 5 is a modified form of lock-bar.

A A represent the draw-heads of two adjacent cars, each provided with my improvement. As the draw-heads are similar in construction, I will describe one of them only.

Draw-headAis constructed with the flanges B and 0, formed on each side of the recess D,

by means of which lateral displacement of the opposite draw-head is prevented, the forward portion of the draw -head forming a guide, E. Within the draw-head is formed a socket, F, in the rear of which is pivotally secured the locking-jaw G by means of a vertical bolt, H, secured in the head. The jaw is provided with thelaterally-proj eetingshoulder I, the forward portion of which is beveled, as shown, whereby the jaws upon opposite draw-heads are conveniently forced into the interior of the recess D, and the inner edges of the shoulders I are clamped in position. Extending through the outside ofthe drawhead and opening into the socket F is formed the slot or opening J, through which passes the arm K,- secured to the rear of the lockingjaw G, or formed integral therewith, as preferred. The outer end of said arm is pro- Vided transversely with the perforation L, adapted to receive a link, M, or other connecting device attached to the gravity-bar N, the said bar being 'pivotally secured betweenthe arms 0, formed integral with the draw-head at or near the top thereof. The inner end of the gravity-bar N is beveled downwardly and inwardly, as shown, and the link or connecting device M is attached thereto in such manner that when the bar is adjusted horizontally relative to the draw head the shoulder I is drawn within the socket F. Near the center of the gravity-bar is pivotally attached the rod P,which extends to the top of the car, and is provided at its upper end with the handle I Q. To the top of a car, or near thereto,-is secured a rest, R, provided at its outer end with a hole, S, through which passes the rod P. The bar is loosely mounted at its lower end in a suitable socket, which will permit the bar to be rotated. The rest R is provided with a hook, S, to which one of the arms, T, of the bar is secured when it is desired to elevate the gravity-bar and prevent the operation of the coupling devices.

When in use upon platform-cars, the car may be provided with a suitablehoolgand the lower arm can be used to secure the rod in elevated position. When it is desirable to dispense with the rod P. the locking-jaw G can be locked out of possible action by inserting a pinthrough the perforation U, formed in the arm K.

When the cars are coupled, by raising the rod P, the gravity-bar N is elevated and the locking-jaw G will be drawn. into the socket F, thereby detaching the couplings. When the rod P or gravity-bar N is lowered, the lower beveled end thereof will bear against the end of the arm K, thereby forcing the locking-jaw out of the slot, and the sameis ready for adjustment.

In the modification shown in Fig. 6 the draw-head is provided with the recess D and the flangesB and C, by means of which lateral displacement is prevented. The guideframe a, is provided transversely with the verticallyelongated slot 12, in the rear of and adjoining which is secured the laterally-extending bracket 0, the head d of which is provided with the vertically-elongated slot 6. A locking-jaw, f, is located in the said slots 12 and e, and is secured to a gravity-bang, by means of the arm or pin h, which is rigidly secured thereto, the said pin passing through the elongated slot t,

v formed in the side of the bracket 0. The gravity-bar g is pivotallysecured to the side of the bracket, and is loosely attached to the pin h by means of the vertically-elongated slot j, formed in the pivoted end of the bar.

The action of the modified form is similar to that described in the preferred construction, and the same can'also be provided with rod P, adapted to be operated as described.

By my improved car-coupler the cars may be automatically coupled without requiring the-brakesman to enter between the cars, as the locking-jaws are in constant adjustment unless otherwise placed. The cars can be conveniently uncoupled from either side or from the top.

As it is evident that many slight changesin the construction and relative arrangement of parts might be resorted to without departing from the spirit of my invention, I would have it understood that I do not restrict or limit myself to the exact construction and arrangement of parts shown and described.

I am aware that it is old to provide a drawhead with a bell-crank lever pivoted at its elbow Within the coupler, and provided at one end with an arrow-head forengaging a similar device on the adjacent draw-head and at its opposite end with a weight; and also that it is old to construct a draw-head with projecting parts for engaging correspondingly-shaped recesses in the adjacent draw-head, and with a pivoted jaw for engaging the jaw of said adjacent draw-head, and hence I make no claim, broadly, to such constructions.

Having fully described my invention, what I Patent, is

1. In acar coupling, the combination, with a draw-head and locking-jaw secured thereto,

of a gravity-bar pivotally secured to said drawhead and pivotally connected with the jaw, whereby the same is automatically locked, substantially as set forth.

2.' In a car-coupling, the combination, with a draw-head having a slot formed in one side thereof, of a locking-jaw pivoted in said slot and a gravitybar pivotally secured to said drawhead and pivotally connected to said jaw, whereby the jaw is automatically locked, substantially as set forth.

3. In a car-coupling, the combination, with a draw-head and aslot or recess formed in the guide-bar thereof, of a jaw pivoted in said recess, an arm formed laterally on the jaw extending through said guide-bar and pivotally connected to a gravity-bar, whereby the jaw is automatically locked, substantially as set forth.

4. In a car-coupling, the combination, with a draw-head having a recess or slot formed therein, of a locking-jaw pivoted in said recess and pivotally connected with a gravity; bar and means for locking the jaw out of possible engagement, substantially as setforth.

5. In a car-coupling, the combination, with a draw-head and a locking-jaw secured thereto, the said jaw having a laterally-extending arm through said bar, of a gravity-bar pivotally secured to said arm, and an upright rod pivotally secured to the bar, and means for lockingthe rod in vertical adjustment, substantially as set forth.

6. The combination, with a draw-head provided with a side extension, of a lock'bar pivotally secured in said extension and a gravity-bar for automatically throwing the lock-bar into locked adjustment, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

DAVID LIPPY.
