CAR==COUPLING.

SPECIFICATION forming part of Letters Patent No. 640,225, dated January 2, 1900. Application filed March 31,1899. Serial No. 711,272. (No model.)

To @ZZ 107mm 'nmyconccrm Beit known that I, WILLARD F. RICHARDS, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Car-Couplings, of which the following is a specification.

This invention relates to a car-coupling of the Master Oar-Builders type in which the 1o coupling-knuckle is locked by a verticallymovable lock which is arranged transversely in the draw-head and connected by a longitudinal horizontal pivot to the knuckle side of the draw-head, while the free end or head x5 of the lock is arranged on the opposite or guard-arm side of the drawhead. A coupling of this kind is described and shown in my application for Letters Patent iiled February 2l, 1809, Serial No. 706,327, to which referzo ence is made for a more complete description of such coupling.

The object of this invention is to provide the lock of this coupling with an actuating device which is operated from the knuckle 2 5 side of the draw-head by an upward pull in order to render the coupling suitable for use on cars with low platforms-for instance, iiat cars, in which the platform is arranged so closely to the top of the draw-head that no 3o room is available above the draw-head for an actuating device.

In the accompanying drawings, consisting of two sheets, Figure l is a front view of a draw-head provided with my improvements,

the view being partly a front elevation and partly a vertical cross-section and showing the. lock in its lower locked position. Fig. 2 is a similar view showing the lock raised. Fig. 3 is a perspective view of the actuating- 4o lever of the lock. Fig. 4f. is a perspective view ot' the lock. Fig. 5 is a front elevation of the draw-head, showing' the front portion of the knuckle removed and the tailpiece of the lock in cross-section. Fig. 6 is a longitudinal vertical section of the lower portion of the drawhcad in line G (5, Fig. l. Fig. 7isa horizontal longitudinal section through the draw-head in line 7 7, Fig. 1.

Like letters of reference refer to like parts 5o in the several figures.

A represents the chambered drawdlead,

which conforms to the well-known contour-l lines adopted by the Master Car-Builders Association and which has at one side the usual guardarm a. B represents the coupL 55 ling-knuckle, which is pivoted to the opposite side of the draw-head and which is composed,

as usual, of the coupling-ears h, hub h, and tailpiece b2.

O represents the lock, which engages with 6o the tailpiece h2 of the knuckle for retaining the latter in its closed position. The lock is arranged transversely in the draw-head and pivoted in the chamber thereof, on the knuckle side, bya longitudinalhorizontal bolt or pin D, so that the head c of the lock, which hooks over the tailpiece of the knuckle, reaches over to the guard-arm side of the chamber and is capable of swinging vertically in the same. 7o

E represents the kicking-lever or kicker whereby the knuckle is automatically thrown into its open position when released by the lock. This kicking-lever may be operated in various ways-for instance, by a spring device similar to that which is shown in Letters Patent of the United States No. 554,310, granted to me February 1l, 1896, or, as shown in the drawings, by a nose c", which is formed on the upper side of the lock in such a posi- 8o tion that it strikes the rear arm of the kicking-lever in the act of fully raising the lock, and so swings the lever forwardly and opens the knuckle.

F represents a friction-shoe which may be used in the lock for holding the same more securely against accidental upward movement. The shoe is pivoted in a recess in the head of the lock and bears against the adjacent inner side of the draw-head when the 9o lock is in its lower position.

The lock is provided on its l'ear side with a depending stiffening rib or web G, which terminates below the pivotal portion or hub of the lock in an actuating heel or arm g.

Il represents the actuatingdever whereby the lock is raised for releasing the knuckle. This lever is arranged transversely and vertically underneath the pivotal portion or hub of the lock and is pivoted on a longitudinal roo pivot t'. The short arm 7a of this lever pro jects upwardly and bears with its inner inclined face against the outer side of the heel g of the lock, while the long arm h of the lever projects outwardly through an opening 7c in the knuckle side of the draw-head and is connected by an upwardly-extending operatingchain Z with an operating-lever L. The latter is mounted on the inner end of a horizontal rockshaft m, which is arranged on the knuckle side of the draw-head. This shaft is operated at its outer end by any suitable means.

By raising the outerarm h of the actuatinglever H its inner arm h is swung inwardly and by pressing against the heel of the lock swings the latter upwardly, as shown in Fig. 2, thereby releasing the knuckle. Upon releasing the actuating-lever H the overhanging Weight of the head of the lock returns the latter and the actuating-lever to their former positions.

I claim as my invention 35 Witness my hand this 24th day of Marchi WILLARD F. RICHARDS.
