CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 748,874, dated January 5, 1904.

Application filedlllarch 13, 1903- Serial No. 147,531. (No modem clear, and exact description as will enable any one skilled in the art to which it appertains to make and .use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a car-coupling, and more particularly to that class of carcouplings usually known as the J anney type, and consists of a pair of coupler-heads, each provided with a pivoted knuckle, and means for locking the knuckles in engagement with each other.

One object of my invention is to provide means for preventing one of the couplingheads from falling down upon the track when it is broken off or pulled out, thus endanger ing the remaining cars of the train.

Another object of my invention is to provide means for rigidly coupling-theheads together when one or both of the knuckles have become disabled.

My invention consists in part in the combination,with a draw-head and pivoted kn uckle, of a forwardly-projecting stop rigidly carried by the upper face of said knuckle, said stop being elevated above the upper face of the coupler,whereby vertical play is permitted between the said coupler and a second coupler with which it cooperates.

My invention alsoconsists in various other novel features and details of construction, all of which will be described in the following specification and pointed out in the claims affixed thereto.

In the accom pan ying drawings, which illus-.

assumed by the parts when one of the heads is broken off or pulled out.

Like marks of reference refer to similar parts in the several views of the drawings.

10 represents the drawbars, each of which is provided with a coupling-head 11 of any usual form. Each of the-coupling-heads 11 is provided with a knuckle 12. The knuckles 12 are pivoted in position by means of the usual knuckle-pins 14, passing through eyes 15 on the heads 11. Each of the knuckles 12 is provided with a rearwardly-extending frame 16, which is held by means of a pin 17 or any of the usual and well-known devices, so as to lock the knuckles in engagement. In order to prevent one of the draw-heads from falling upon the track when it becomes broken off or pulled out, I provide each of the knuckles 12 with a forwardly-projecting stop 18, which stop is formed integral with the upper face of the knuckle 12 at a point intermediate of its length. The stopsl8 are elevated above the faces of the draw heads by means of standards or stems 19, Figs. 4 and 6. By thus raising the stops 18 above the faces of the draw-heads vertical play is allowed between the two draw-heads, and two cars can be coupled together when their draw-heads are not exactly upon the same level, as often happens in practice. In case one of the drawheads breaks off or is pulled out from the car. carrying it it will drop down, as shown at the right hand of Fig. 4, until its stop 18 comes in contact with the upper face of the draw-head 11 of the opposite car. This will prevent further movement of the draw-head, and the weight of the rear end of the drawhead will cause the two draw-heads to be clamped, owing to theinclined position taken case only one of the knuckles becomes disabled the short bar 20 is used, as shown in Fig. 2, one end of the said bar 20 being secured to the knuckle 12 by means of a pin 22 and the other end secured to the drawhead by means of a pin 23, passing through an opening 24, one of which is formed in each draw-head. In case both knuckles become injured the heads are connected together by means of the long coupling-bar 21, as shown in Fig.3, the bar being held by means of two pins23,passingthroughthe openings24 above referred to. By using solid bars having openings in their ends when the draw-heads are rigidly connected together no play is allowed between them, as would be the case if ordinary coupling-links were used.

I am aware that it has heretofore been proposed to provide the draw-head of a car with stops arranged in pairs above and below the head and engaging directly with the head or knuckle of the opposite car. I am also aware that it has been proposed to provide the drawhead of a car with stops pivotally mounted on the knuckle-pin. I am also aware that it has been proposed to provide the knuckle of a draw-head with a pair of stops formed integral with the pivoted end of the knuckle andengaging directly with the draw-head or knuckle of the opposite car. I am also aware that it has been proposed to couple two drawheads of the Janney type together by means of ordinary coupling-links after the knuckles have become injured, and hence I do not claim such constructions.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a coupling device, the combination with a draw-head and pivoted knuckle, of a forwardly-projecting stop rigidly carried by the upper face of said knuckle intermediate of its length, said stop being elevated above the upper face of the coupler, whereby vertical play is permitted between said coupler and a second coupler with which it cooperates.

2. In a coupling device, the combination with a draw-head and pivoted knuckle, of a forwardly -projecting stop formed integral with the upper face of said knuckle intermediate of its length, said stop being elevated above the upper face of the coupler, whereby vertical play is permitted between said coupler and a second coupler with which it cooperates.

The combination with a pair of cooperating coupling devices, each provided with an opening for the passage of a coupling-pin,

of a pivoted knuckle for each of said coupling devices, each of said knuckles also being provided with an opening for the passage of a coupling-pin, a pair of coupling-bars of unequal length, each provided with a pair of openings, and coupling-pins for rigidly connecting said coupling devices by said coupling-bars when one or both of said knuckles are disabled.

In testimony whereof I have hereunto set my hand and affixed my seal in the presence of the two subscribing witnesses.
