CARS-COU'PLING.

SPECIFICATION forming part of Letters Patent No. 322,814, dated July 21, 1885.

Application filed May 1G, 1885.

To all whom it may concern:

Be it known that I, ALBERT L. ERLER, a citizen of the United States, residing at Lawler, in the county of Chickasaw and State of Iowa, have invented new and useful Improvements in Car-Couplings, of which the following is a speciiication.

This invention relates to improvements in car-couplings, and particularly to that cla-ss in which a hinged bail and hooked draw-bar are employed to couple the cars. The bail is hinged to rods having a yielding or spring connection with the bed-frame of the car independent of the draw-bar,which latter is pivoted to the bed-frame and is held parallel to its draft by a connection pivotally attached to the rear end bars to abut and readily pass one another when the cars come together, and to reduce the abrasion caused by the one sliding against the other when'coupled.

The invention consists in the construction, arrangement, and combination of parts, as more fully hereinafter set forth and claimed.

In the accompanying drawings, Figure l represents a vertical longitudinal section of a portion of two cars with my improvements attached; Fig. 2, a sectional plan view of the same on line x .tof Fig. l. Fig. 3 is a bottom plan view of a part of a car-body to more clearly show the coupling-connections; Fig. 4, a front view of a car-body with my improved coupling; and Fig. 5 shows the draw-bar.

The coupling bail or link A is hinged to rods B, which pass through openings in a sill-bar, C, and are connected at their rear ends to springpulls d, seated within the bolster M of the carframe. The pull-rods pass through a metallic bushing iitted within the bolster, and have coiled springs d thereon with their points of resistance between washers on the rods, and sockets (Z2, formed within the bolster. Pins di pass through the forward ends of thepull-rods (No model.)

d, to limit their inward mov-ement and hold the bail-connections in their normal positions. The draw-bar E has a top hook formation, a, forward of which a long narrow roller, e, is journaled in plates e,secured to the upper and lower sides of the draw-bar, the sides of said draw-bar tapering or converging to the side of the roller. mortise or recess in the sill-bar C, and is pivoted therein by a bolt or pin, F. A loop-rod, G, is pivotally connected with the rear end of the draw-bar by a screw or pin, f, passing through an eye, g, formed by doubling the rod on itself. The ends of the rod G pass through openings in the bolster and extend a The draw-bar passes through a slight distance beyond the same, and are connected by a cross-head, g. Coil-springs g2, on the ends of said rods between the cross-head and bolster, normally serve to keep the drawbar parallel with the draft of the car, and permit a slight forward yielding of the draw-bar in case of any abnormal strain coming thereon. To allow for such forward movement of the -draw-bar, the opening therein, through Which the pin F passes, is slightly elongated, asl clearly shown in Fig. 2, while the pivot-connections F g allow the coupling ends of the draw-bars to have a limited lateral movement, so that they may pass each other on either side in coupling.

To operate the bail, chains I are attached to a shaft, J ,vertically journaled in suitable bearings to the front of the car-body, and are connected to the arms of the bail, the one passing direct, the other passing over a pulley, K,

mounted in a bearing attached to the car nearly over the side of that side of the bail farthest from the operating-shaft. A

When it is desired to couple the cars, the brakeman rotates the shaft J from the top of the car by means of the hand-wheel j, thereby raising the hinged bail,which is limited in its upward movement by contacting with the bottom of the car-body, so that it stands at a forward inclination from the car, and when the shaft is released the bail will fall and en gage the draw-bar hook of the carto be coupled.

To assist the gravitating movement of the bail, its forward end-is weighted.

To uncouple the cars, it is only necessary to rotate the shaft J, when the chains will be IOO Wound thereon and cause the disengagement of the bail from the draw-bar of the coupled ear.

It will be seen that when the cars come together the draw-bars of each will guide past and overlap one another, and allow the momentum of the moving car to spend itself on the bumpers N on either side ofthe draw-bars.

I claiml. In combination with a draw-bar having a-top hook, a, and pivotally connected with shaft vertically journaled to the front of the car at one side of itsfc'entifchains attached to said shaft, the one passing direct to the nearer side of the bail and the other passing over a pulley attached to the car nearly over the other side of the bail to which the chain is attached,substantially as shown and described.

4. 'Ihe herein-described earcoupler, con` sisting of a draw-bar, E, having a top hook and aslot, and pivotally connected to the carframe by a pin, F, passing through said slot, a loop-rod, G, pivoted to the rear end of said draw-bar and held under tension by springs in line with the draw-bar and the car, in combination with a bail, A, hinged to rods B, connected to the bolsters of the car by springs,

substantially as described. l

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

' ALBERT L. ERLER.
