CAR-COUPLING.

Specification of Letters Patent.

Patented Feb. 20, 1906.

Application filed October 30,1905. Serial No. 284,987.

To all whom, it may concern.-

Be it known that I, GUsTAF A. HERMAN- SON, a citizen of the UnitedStates, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Couplers, of which the following is a specification.

My invention relates to improvements in car-couplers.

The object of my invention is to provide a car-coupler of a simple, efficient, and durable construction composed of the fewest possible parts and each of a simple plain form caable of being easily cast or manufactured which will properly perform all necessary or required functions, including the setting or supporting of the lock in position for coupling and also in position for uncoupling and the automatic throwing of the knuckle open and which at the same time will afford great additional security and safety over the couplers heretofore in use in case the pivot-pin breaks or becomes lost or mischievously removed.

My invention consists in the means I employ for accomplishing the above objects or resultsthat is to say, it consists in a coupler of the ordinary Master Car-Builders type in connection with the forked draw-head of a knuckle pivotally connected thereto and having its rear arm or tail furnished with a transversely-extending slot or passage-way, and an upwardly-extending incline or cam, and a vertically-movable lock provided with an integral knuckle-throwing leg fitting in tail, and having a foot or projection adapted to engage the upward incline or cam on the knuckle-tail, and thus throw the knuckle open when the lock is lifted to the required extent.

It further consists, in connection with these parts, in having the knuckle-throwing cam or incline on the knuckle-tail on the pivot-pin side of the transversely-extending slot to thus bring such cam or incline nearer the pivot or center of motion of the knuckle, so

that the cam or incline may serve to throw 'the knuckle completely open by an easy movement and without unduly lengthening the transverse dimension of the knuckle-tail. As in my invention, the knuckle-throwing leg of the lock extends throughlthe tailof the knuckle in the transverse slot therein. It also serves as a strong and efficient means for holding the knuckle in the draw-head independent of the pivot-pin in case the latter should break, be removed, or become lost.

My invention further consists in connection with the before-mentioned parts, in providing the lock with a lock-set ledge or shoulder adapted to engage the floor of the draw-head for setting orsupporting the lock in position for uncoupling. The lock is preferably provided with a further lock-set ledge at the lower end of its knuckle-thrower leg. The lock is further provided; with a lock-set ledge or shoulder adapted to engage the tail of the knuckle for supporting the lock when the knuckle is partially open. The rear arm or tail of the knuckle is further provided with a ledge or shelf engaging the lower end of the knuckle-thrower leg of the lock to support the lock in its raised position when the knuckle is completely open.

My invention further consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a central vertical longitudinal section of a car-coupler embodying my invention. Fig. 2 is a similar view showing the lock in its raised position. Fig. 3 is ahorizontal section on line 3 3 of Fig. 1. Fig. 4 is a section on line 4 4 of Fig. 3. Fig. 5 is a detail horizontal section on line 5 5 of Fig. 1. Fig. 6 is a detail horizontal section of the draw-head. Fig. 7 is a detail front elevation of the lock. Fig. 8 is a detail perspective view of the knuckle, and Fig. 9 is a detail section on line 9 9 of Fig. 8.

In the drawings, A represents the drawbar; B, the draw-head having the customary pivot-arm b and guard-arm b.

C is the pivot-pin, I) the knuckle, and F the gravity-lock, the same having a knucklethrowing leg f and a lock-set leg 7. The knuckle D has the customary front arm or nosed and rear arm or tail (1. The rear arm or tail d of the knuckle has a transverselyeXtending slot or passage-way (Z to receive the knuckle-throwing leg of the lock F. This slot or passage-way d in the knuckletail ispreferably curved about the pivot of the knuckle as a center and has a slight enlargement OZ in its front wall (1 to permit the lock to tilt slightly forward at its lower end and backward at its upper end to enable the lock-set shoulders or ledges f 2 f on. the lock to properly engage the lock-set ledges or shoulders I) b in the bottom web or floor 5 of the draw-head adjacent to the openings b b therein, through which the knuckle-throwing and lock-set legs f f of the lock F project. The knuckle-tail d is also provided on the outer or pivot-pin side of the slot d with an upwardly-extending incline or cam 0Z adapt ed to be engaged by the foot or projection f on the knuckle-throwing leg f of the lock F, and thus cause the knuckle to be automatically thrown open when the lock is lifted to the required extent. The tail or rear arm (1 of the knuckle D is also furnished with a shelf or incline (1, adapted by its engagement with the lower end of the knuckle-throwing leg f to support the lock when the knuckle is open. The lower end of the knuckle-throwing leg f of the lock is provided with a beveled or inclined face f 5 to adapt it to properly ride up the incline or shelf d the knuckle swings open. The lock F is also provided with a shoulder or ledgef, adapted to engage the knuckle-tail and support the knuckle thereon as the knuckle begins to swing open. The knuckle D also has on its tail or rear arm a hook or projection d", which when the knuckle is closed engages the pro jection or shoulder b on the draw-head B, and thus affords an additional anchorage for holding the knuckle in the draw-head and in part relieving the pivot-pin C from strain. The foot or projection f on the knucklethrower leg f of the lock F not only serves by its engagement with the knuckle-tail to automatically throw the knuckle open," but also serves as a means for preventing the lock from being entirely removed from the coupler without first removing the pivot-pin O and taking the knuckle itself out. In other words, it prevents the lock F from being raised too high. For this purpose also the knuckle-throwing cam or incline d is furnished with an extension (i slightly beyond the point necessary for fully throwing the knuckle open, and which .by engagement with said foot or-projectionf of the lock prevents the lock from being removed when the knuckle is entirely open. The curved and inclined passage-way (Z in the front wall of the slot d in the knuckle-tail for the foot or projection f 4 of the knuckle-thrower leg f has an open mouth d, so that when the lock is raised to the proper position and the pivotpin C removed the knuckle can be removed from the draw-head and from its engagement with the lock-set leg f and footf This permits the ready removal of the parts and their easy assembling. As the knuckle-throwing leg f of the lock F extends through the knucof the knuckle-tail askletail,it affords a very firm and strong ad ditional means for connecting the knuckle with the draw-head, and as the slot F in the lock F between the main portion of the lock and knuckle-throwing leg f fits closely the portion d of the knuckle-tail thus straddled by the lock and its knuckle-throwing leg the knuckle cannot either open or be drawn out of the draw-head even if the pivot-pin C should break or be mischievously removed. My invention thus affords great additional strength, security, and safety to the coupling and to the train connected thereby.

G is the lifting-lever connected by a chain or link 9 with the eye F of the lock F.
