CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 454,550, dated June 23, 1891.

Application filed February 5,1891. Serial No. 380,340. (No model.)

To all whom it may concern..-

Be it known that I, JOHN W. WAGNER, a citizen of the United States, residing at Dalton, in the county of Vayne and State of Ohio, have invented certain new and useful Improvements in Car-Couplings; and I do hereby declare that the following' is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this speciiication, and to the letters of reference marked thereon, in which- Figure I is a View of a portion of a drawhead. Fig. 2 is a view showing a draw-head in proper position with reference to a car, illustrating the position of a draw-head properly attached or coupled. Fig. 3 is a top view of the draw-heads, showing them properly located and attached together. Fig. 4 is a view of a portion of a draw-head, showing its pivoted jaw released. Fig. 5 is a view showing the pivoted jaw removed. Fig. 6 is a longitudinal section of one of the draw-heads. Fig. 7 is a detached View of the locking-bar. Fig. 8 is a detached view of one of the springs. Fig. 9 is a detached view of the pivoted jaw, showing a link connected thereto.

The present invention has relation to careouplings; and it consists in the different parts and combination ot' parts hereinafter described, and particularly pointed out in the claim.

Similar letters of reference indicate corresponding parts in all the gures of the drawings.

In the accompanying drawings, A represents the draw-head, which is attached to a car in the ordinary manner. To the drawheads A are pivotally attached the couplingjaws B, which jaws are curved so as to form the hook a. The arms C are substantially of the form shown in Figs. l, 3,-1, and 9, and, as shown, two arms are located upon the coupling-jaws B. The opposite sides of the drawheads A are provided with the concaved extensions b, which are for the purpose hereinafter described.

IVithin the draw-head A is located the locking-bar D,'which bar is provided with the arms d, said locking-bar being for the purpose ot' holding the pivoted jaws B in the positions illustrated in Fig. 3.

In use, when it is desired to couple thev draw-heads A together, the pivoted jaw B in one of the draw-heads is released by drawing together with the arms O, to turn on the bolt E until the arms O have passed the arms CZ ot the locking-bar D, at which time the jaws B will be locked or hooked together, and at the same time the locking-barD will be automatically forced forward by means of the springs F, thereby securely locking the pvoted jaws B.

To the locking-bar D are attached the rods H, which rods are for the purpose of holding in proper position the springs F. It will be understood that as the locking-bar D is drawn backward and out of conta-et with the arms C the springs F will be contracted and said springs will be free to expand when the locking-bar D is released.

For the purpose of providing a means for drawing the locking-bar D backward-the shaft I is provided, to which shaft is attached the chain or cord J, and the chain wrapped around the shaft; or, if desired, a lever may be provided to attach the'chain and operate the same, as it is immaterial as to the means used for drawing the locking-bar backward. It will be understood that if a shaft such as I is used it should be journaled to the car.

For the purpose of providing a means for coupling to draw-heads not provided with my improved device I provide the notches K, which notches are for the purpose of receiving one end of the link L, the opposite endof said link being entered in the draw-head in the ordinary manner.

For the purpose of providing a means for coupling cars of unequal height I provide a series of notches, such as K, and locate the link L in the notch, which will give the link L the desired adjustment. The link L is properly held to the pivoted jaws I3 by means of the pin M.

ICO

For the purpose of providing` a guide for the looking-barD the partition N is provided, and Ithe arms d located one above said partition and the other below it, said partition also serving the purpose of strengthening the draw-head.

It will be understood that the chain J is to be attached to the looking-bar D in any con- Venient manner.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isw

of two witnesses.
