WILLIAM C. WATSON, OF PATERSON, NEW JERSEY.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 510,660, dated December 12, 1893. Application filed October 4,1893- Serial No. 487,175. (No model.)

To all whom it may concern:

Be it known that 1, WILLIA C. Wnrsoiv of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Car-Couplings, of which the following is a specification.

This invention relates to that class of couphugs the principal elements of which are books pivoted and having lateral movements Within the draw-heads, the coupling action being effected by the engagement of two such hooks one on each of two cars to be coupled.

I will describe in detail a car-coupling embodying my improvement and then point out the novel features in the claims.

Figure 1 in the accompanying drawings is a plan view, partly in section, of one member of a car-coupling embodying my invention. Fig. 2 1s a side view of the same. Fig. 3 is a front view of the same.

Similar letters of reference designate corresponding parts in all the figures.

A is the draw-head of the hollow construction common to couplings of its class and having pivoted within its rear part the rear end of the shank B of the coupling-hook B, the said hook being pivoted by a pin a to the drawbar 0 and being capable of a limited sliding movement in slots 0 provided in the top and bottom of the draw-head as indicated in dotted outline 'in Fig. 1. The front end of the draw-head is closed as shown at cl, on that side toward which the hook moves for-coupling and has an opening in the other side as shown at e e 111 Fig. 3, to permit the movement ofthe hook in a direction for uncoupling, and in order to keep this opening closed the coupling-hook B has provided on its back a lateral wing f shown in Figs. 1 and 3, the said wing sliding across the face of the draw-head over said opening (2 e. A spring 0 is applied within the draw-head to act upon the coupling-hook to keep it constantly pressed in a direction for coupling.

H I J designate a lever for pushing aside the coupling-hook B for uncoupling, the said lever being pivoted into the draw-head by a pin g, which constitutes its fulcrum, not being connected with the coupling-hook but being arranged to move the said hook aside by simply pressing against it, the said lever projecting through and from the draw-head sothat it may be operated by hand by a man standing at the side of the car without going between two cars. This lever is represented in Fig. l as of peculiar form having a T-head I J from near the middle of which the arm H to which the power is applied is projected in the form of a hook is from which it is extended in any form, as straight, convenient for operation. The lever thus constructed, so far as its operation is considered, is like that of an elbow-lever of which the arm H to which the power is applied, would be extended in one direction directly from the fulcrum g and the other arm at the end of which is the point of application J, would be extended in another direction directly from the fulcrum.

The object in making the lever of the .T- headed and hooked form above described is to facilitate its insertion into the hollow drawhead which, if it were in the form of an ordinary elbow lever, would require more room than could conveniently be provided within the draw-head between the shank of the coupling-hook and the side of the draw-head. To provide for the insertion of the head I J of this lever into the draw-head, a long slot Z is provided in the side of the draw-head in front of the fulcrum 9. To insert the lever the end I of its hooked portion is first inserted through the slot with the arm H nearly parallel with the side of the draw-head and then by gradually drawing out the said arm H and pushing back the head I J of the lever the end I of the head is brought into a suitable position to permit the fulcrum pin g to be droppedin through the openings provided in the drawhead and the leverrespectively. An opening .011 is also shown in the draw-head opposite the fulcrum g, but this opening is immaterial.

' To operate the coupling-hook by the method above described the arm H of the lever which is accessible from the side of the car is pulled toward the outer end of the draw-head. When this leveris released the spring always throws the hook into the coupling position. If, however, it should be desired to provide for the operation of the uncoupling lever H I Jfrom the platform or roof of a car, such provision may be made by means of a crank or cam applied to said lever in connection with an upright shaft and hand wheelin amanner which is common and Well understood.

\Vhat I claim as my invention is- 1. In a car-coupling, the combination of a hollow draw-head, a couplinghook having its shank pivoted in the rear portion of said drawhead, and an uncoupling lever pivoted in and projecting laterally through and from the draw-head and bearing against one side of the said hook for the purpose of pushing aside the said hook, substantially as herein set forth.

2. The combination with the hollow drawhead havinga slot Z on one side, the couplinghook B B pivoted Within the said draw-head to move laterally therein and a T- headed hooked lever H I J passing through said slot Z and having its fulcrum g in the said draw-
