CARI-COUPLING.

SPECIFICATION forming part of Letters Patent No. 608,056, dated July 26, 1898. Application filed March 7, 1898. Serial No. 672,932. (No model.)

T0 at whom, it may concern.-

Be it known that we, HERMFJNEGILDE Lor- SELLE and AIME LoIsELLE, of the city of Winnipeg, Manitoba Canada, have invented a new and useful Improvement in Oar-Couplings, of which the following is aspecification.

The object of our invention is to provide a simple, cheap, and effective car coupling which shall couple the cars automatically when they come together, which will not come apart accidentally nor cramp and bind in turning curves, and which may be adapted also to coupling with cars having the ordinary construction of draw-bar and the ordinary link-and-pin coupling. 7

It consists in the peculiar construction and arrangement of the draw-heads, couplingjaws, and means for operating them, as will be hereinafter more fully described, and pointed out in the claims.

Figure 1 is a side elevation of the two drawbars with parts of the car sustaining the same, the draw-bars being disconnected and one of them broken away in section to show the means for coupling with cars having the or-" dinary form of draw-bar. Fig. 2 is a plan view of the two draw-bars coupled. Fig. 3 is a perspective detail of one of the couplingjaws, and Fig. 4 a similar view of one of the special forms of links for coupling with ordinary draw-bars.

In the drawings, A. represents one of our improved draw-bars. This may have the usual connection with the timbers of the car to adapt it to either freight or passenger cars and is made with a hollow metal head having an open front and top. In the back end of this hollow head, near the top, there is hinged upon a horizontal bolt 1) a vertically-swinging jaw B. This jaw has an elongated barrel 1), which envelope the horizontal bolt b and has a perforated lug b at the top, by which it is lifted, and its front end is turned inwardly at- Z) to form a grappling-hook. This hook is on its inner face formed into corrugated surfaces which intermesh or fit into similar corrugated surfaces on the face of the jaw of the other draw-bar, while the outer face of these hooks are made tapered or wedge shaped, so that when the two grappling-hooks of the opposite draw-bars come together one will ride up over the other and, dropping behind, will have its corrugations interlocked with those of the other face. This makes a positive connection of the two hook-shaped jaws, but gives sufiicient play, so that they do not cramp and bind in turning curves.

The two draw-bars of our car-coupler couple automatically when they come together, so as to avoid all danger involved in going between the cars and are disconnected or uncoupled by hand either from the side or top of the car as follows: C is a rock-shaft journaled in bearingson the sides of the car and having a cranked portion 0 in the middle, which is connected by short rods or links 0 with the perforated lug on top of the hook-shaped jaws. These rock shafts are provided at their ends with crank-arms n or hand-Wheels, by turning which either jaw may be raised about its horizontal center bolt, so as to be lifted above and out of engagement with the other jaw. To operate this rook-shaft from the top of the car, a rod M extends upwardly to the top of the car and is there connected to an elbow-lever L.

To enable our draw-bars to couple with those ordinarily in use employing a link-andpin connection, we form the draw-bar with a lower chamber or throat in the thickened same is formed also a vertical pin-hole d. In this throat there is arranged a special form of link E,-(see Fig. 4,) made of a rod of iron bent into a loop shape at one end and at the other having one end bent around the shank of the other in the form of an eye, while the other and longer end is extended at right angles to' the body of the link and formed into a handle 6, which projects outside of the draw-bar and by which the link may be "handled from the side of the car without going between the cars. This link embraces a coupling-pin p in our draw-bar and may be protruded by the handle far enough to receive the coupling-pin of an ordinary draw-bar, as shown in Figil, or be drawn back into its throat and out of the way.

To prevent the accumulation of snow, rain, or dirt in the head of the draw-bar, a taper ing bottom is formed with a discharge-hole h in the center.

In defining our invention with greater clearness we would state that we are aware "lower lip D of the draw-bar, and through the r more heavily than the next or when the carspass over uneven rails or a rough road-bed. To prevent the separation in vertical direction is the object of the corrugation on the adjacent faces of the coupling-jaws, and said corrugations are made in a peculiar way, as follows: Referring to Fig. 3, each jaw has in the middle a recess with a lip at top and bottom of the recess, and just beside this recess is a lug partially closing the end of the recess and having a notch at the top and bottom of the lug. Two corrugated jaws of this character intermesh perfectly and lock against vertical as Well as sidewise motion.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a car-coupling the combination of a draw-bar having a hollow coupling-head, open at the top and front end and having a drainage-hole in the bottom, and two coupling-jaws hinged at their rear ends upon horizontal axes and having their front ends made with tapered noses each provided on its inner grappling-face with a central recess having a lip at top and bottom of the same, and also a lug partly closing one end of the recess and having a notch above and below the lug substantially as and for the purpose described.

2. A car-coupling having a pair of jaws pivoted 011 horizontal axes and having tapered noses and grappling-faces, each face having a central recess with a lip at top and bottom of the same, and a lug partly closing one end of the recess and having a notch at the top and bottom of the lug substantially as and for the purpose described.
