CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 453,978, dated June 9, 1891.

Application filed February 26 1891- To all whom it may concern:

Be it known that I, ELIAS FRANTZ, of Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Couplings, of which the following is a specification.

The present invention consists in improvements applicable to existing railway-cars having pin-and-link couplings, whereby the same are rendered automatic in coupling, and may be uncoupled without necessitating a trainman passing between adjacent cars.

The present improvements are illustrated in the accompanying drawings, wherein- Figure 1 shows in longitudinal vertical section two adjacent draw-heads, the couplingpin of one being shown elevated and that of the other lowered; and Fig. 2 shows a plan view of one of the draw-heads.

In the drawings, A A are chambered drawheads of two adjacent and approaching railway-cars.

B B are the coupling pins thereof, and C is a coupling-link.

Each pin B is pivotally connected at its upper end to the front end of a bar D, the rear end of which is pivoted to a stationary verticalbraoket E, fixed to the draw-head. When the bar D is raised, the pin B is out of connection with the link 0, and when lowered the pin enters the link and so couples the cars. The bar D is maintained in its elevated position by a toggle-joint, the upper member F of which is pivoted to the bar D, and the lower member G of which ispivoted at a to the draw-head or a fixed part thereof. The two members F G of the toggle-joint are connected by a knuckle-joint b. By bending or breaking the joint between the two toggle members F G, the bar D, and with it the coup- This' is automatically effected by the entrance of the coupling-link 0 into the draw-head, having its coupling-pin elevated- The lower toggle member G constitutes in itself a lever, since it is provided with a downwardly-extending extension or tail 11 below its pivot. To this extension is pivoted and suspended by a knuckle-joint c a pawl I. This pawl I is free at all times to Serial No. 382,945- (No model.)

swing forward on its pivot, but cannot swing on its pivot backward beyond a vertical plane when the bar D is raised. When the coup ling-link O enters the d raw-head, it encounters the pawl I, which is then located within the chamber of the draw-head, thus forcing the pawl I and the lower toggle member 0 to swing backward on the pivot 01,, and consequently breaking the joint between the tWo toggle members and allowing the couplingpin to drop into the link. In order to uncouple it, it is only necessary to lift the bar D. This can conveniently be done by a bail J, extending beneaththe bar D, said bail being carried by a rotary shaft K, extending to the sides of the car and having operatinghandles L. If when the uncoupling is effected the pawl I comes in front of the end of the link, it will not interfere with the with drawal of the link, since the pawl will swing forward out of the way.

. I claim as my invention.

1. In a car-coupling, in combination with the draw-head, the bar D, pivoted thereto, and at its front end the coupling-pin, and toggle-joint F G, pivoted at opposite ends to the said bar D and described.

2. In a car-coupling, in combination, the draw-head, bar D, toggle-joint F G, pivoted at opposite ends to the said bar and draw=head, and the swinging pawl I, connected to the said toggle-joint and adapted to be engaged by the coupling-link to trip the coupling-pin, substantially as described.

3. In a car-coupling, in combination with the bar D, pivoted to the draw-head, having the coupling-pin pivoted thereto, and togglejoint composed of the members F G H, the bail J extending beneath the bar D, and having crank-shaft K L, substantially as described.

4:. A chambered draw-head, a coupling-pin, a bar pivoted at opposite ends to said drawhead and pin, and a toggle-joint consisting of two members connected together by a knuckle-joint, the upper of said toggle members being pivoted to said bar, and the lower of said toggle members being pivoted to the draw-head, substantially as draw-head and having a portion extending In witness whereof I have'hereunto signed below said pivot, in combination with a pawl my name in the presence of two subscribing connected by a knuckleoint to said downwitnesses.

wardly-extending portion of said lower toggle ELIAS FRANTZ. 5 member, said pawl hanging Within the cham- \Vitnesses:

ber of the draw-head when said bar is raised, LEWIS GUTTENTAG,
