CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 596,195, dated December 28, 1897.

Application iiled July 13,1897. Serial No. 644,3 89. (No model.)

such as will enable those skilled in the art tov which it ap pertains to make and use the same.

This invention relates to car-couplers; and the object thereof is to provide an improved device of this class which is simple in construction and operation and which is adapted to be connected with both ends of a car, the operation of coupling the cars being automatic and the couplers being adapted to be locked or unlocked from the side or top of the car.

The invention is fully disclosed in the following speciieation, of which the accompany'- ing drawings form a part, in which- Figure 1 is a bottom plan view of the end of a car provided with my improved coupler; Fig. 2, a partial central longitudinal section of the coupler and showing the supports there of also in section; Fig. 3, a sectional end yview of a part of the coupler; Fig. 4, a plan view of a coupler-head and the parts connected therewith, partly in section, and showing in dotted lines the position it occupies when the car is uncoupled; Fig. 5, a plan view showing the coupler-head in the reverse position; Fig. 6, a back view of a movable jaw which is connected with the coupler-head, and Fig. 7 a section on the line 7 7 of Fig. 5.

In thev drawings forming part of this specication the separate parts of my improvement are designated by the same numerals of reference in each of the views, and in the practice of my invention I provide a coupler which comprises a coupler-head 7, which is provided with an outwardly and forwardly directed stationary jaw 8 at one side and at the opposite side with a forwardly-directed stationary jaw 9, with which a movable jaw 10v is connected.

The coupler-head 7 is provided with a backwardly-directed shank 11, and the stationary jaw 9, adjacent to said shank, is provided centrally with an opening 12,which extends therethrough and which opens between the movable jaw 10 and the stationary jaw 8.

The movable jaw 10 is provided with a top plate 13, which is connected therewith by a bolt or pin 14 and a pivot-pin 15, by which the movable jaw is connected with'the stationary jaw 9, and said plate 13 is curved to correspond with the shape of the stationary jaw 9 of the coupler-head and rests upon the coupler-head and said jaw, as shown in Figs. 2 and 5. The movable jaw 10 is also provid ed centrally with a backwardly-directed arm 16, which is of the form shown in Figs. 4 and 6, and the free end thereoc is provided with a curved head 17, which is beveled to correspond with the inner wall of the opening 12 in the coupler-head, and said arm 16 is provided with a forwardly-directed cam or projection 10a and with a backwardly-directed projection 18, on which is formed a head 19, which is provided with an upwardly and rearwardly directed shoulder or projection 20, and the outer ends of the head 19 and of the shoulder or projection 2O are cam-shaped in form,

as clearly shown in Figs. 4 and 6, for the purpose of raising the head 27 of the sliding bar 26 in the operation of coupling the cars.

The shank 11 of the coupler-head passes backwardly through a hanger 21, secured to the end of the car, and which is provided with downwardly-directed jaws 22, which are provided with backwardly-directed arms 23, which support an antifriction-roller 24, on which the shank 11 of the coupler-head rests, and that portion of said shank 11 between the jaws 22 of the hanger is wider than the rear end thereof, and formed therein is a slot 25, in which is mounted a sliding bar 26, which is provided at its outer end with a head 27, which passes into the opening 12 of the coupler-head, and the head 27 of the sliding bar 26 is preferably circular or elliptical in form, as shown in Fig. 2, and is provided at the lower side thereof with an outwardly-directed head 2S and at the front side thereof with projections 29 and 30, and these projections are adapted to interlock with the head 19, formed on the backwardlyedirected eX- tension 1S of the arm 16 of the movable jaw, and the upwardly and rearwardly directed shoulder or projection 20, formed on said head, and in this operation the movable jaws on the adjacent couplers operate in connection with the cams or projections 10 and the plates 13 and force the arms 16 backwardly,

IOO

as will be readily understood, in such manner as to allow the bar 26 and the head 27 to engage the cam-shaped shoulder or projection 2O of the head 19.

Formed in the bottom of the plateI 1 3, which is connected with the movable jawl() and which rests on the stationary jaw 9 of the coupler-head, is an irregular chamber 31, which is shown in dotted lines in Fig. 5, and in which is mounted a spring 32, which is also shown in dotted lines in said ligure, and the free end of the spring bears on a pin 33, which is secured to the stationary jaw 9, and the operation of the spring is to throw the movable jaw 10 outwardly, as shown in dotted lines in Fig. 4.

Passing through the hangers 34, secured to the bottom of the car at each side thereof is a shaft 35, which is provided at each end with a crank 3G, and the shaft 35 passes through the shank 11 of the coupler-head and through an oblong cavity or recess 37 formed in a head 38 at the rear end of the sliding bar 2G, and the shaft 35 is provided with a cam 39, and by turning said shaft the bar 2G may be forced outwardly or inwardly, as will be readily understood, the said cam 39 operating on the forward or rear walls of the cavity or recess 37 when the movable jaw 19 of the eoupler-head is in the position shown in Figs. 1, 2, and 4. If the sliding bar 25' be forced backwardly by the cam 39 on the shaft 37, the head 27 will be disengaged from the cam 2O on the head 19 of the projection 18 of the arm 1G of the knuckle, and the knuckle, together with the arm 1U, will immediately be forced into the position shown in dotted lines in Fig. 4 by the spring 32, in combination with the plate 13 and pin 33, and it will be understood that when the said head 19 or cam 2O formed therein is released from the head 27 of the bar 26 and the knuckle assumes the position above referred to the shaft 35 is again operated and the said slidin g bar 26 is forced forwardly by the cam 39, and when the cars come together in the act of being coupled the knuckle 19 of the one car will engage with projection 10n and plate 13 of the knuckle of the other car and force the same backwardly, and the cam 2O on the head 19 will raise the head 27 on the sliding bar 26 and will pass beneath the same, andthe said head will drop down behind said cam 2O on the head 19 and securely lock the knuckle in the position shown in Figs. 1, 4, and 5, and thereby lock the cars together, as will be readily understood.

The rear end of the shaft 11 of the couplerhead passes backwardly through a easing 40, formed on or secured to the plate 41, which is adapted to be secured to the bottom of the car, and said casing is provided at the front end thereof with an upwardly-directed extension 42, in which are mounted two transverse rollers 43, the shafts of which move in slots 44, formed in the sides of the casing in which said rollers are mounted, and the said rollers 43 project slightly below the base-plate 41 of the casing 40, and the shaft 11 of the coupler-head is provided on its under side with a longitudinal slot 45, which is deepest at the center and the depth of which gradually decreases in the direction of each. end thereof, as clearly shown in Fig. 2, and I also provide a locking-lever 4G, which is provided with a ilat spoon-shaped head 47, which is provided centrally of the upper side thereof with a longitudinal slot 48, which opens forwardly and which extends backwardly approximately to the rear end of the head 47, and mounted in the slot 4S is a frietion-roller 49, which is provided with trunnions 59, which rest in bearings 5l, formed in the head 47 at each side of said slot 43.

Mounted between the rear end of the lever 4G and a suitable bearing 52, secured to the bottom of the ear, is a strong expansive sprin 53, and in the operation of the device the shank 11 of the coupler-head is free to slide within certain limits between the rollers 43 and the roller 49; but it will be observed that the roller 49 cannot be detached from its position by reason of the manner in which it is supported and by reason of the spring 53, which operates to force the rear end of the lever 4G downwardly, and the head of said lever can only move within certain limits, and when backward pressure is applied to the coupler-head and through said couplerhead to the shank 11, which occurs when the cars are coupled, said shank will move backwardly to a predetermined extent, but cannot move far enough to throw the roller 49 out of the slot 45 in the bottom thereof, and when the weight of the car is thrown on the shaft 11, which occurs when the train is in motion, said shaft 1l of the eoupler-head will move forwardly within certain limits, but cannot move far enough to allow the roller 49 to be thrown out of the slot 45, and it will thus be seen that the shank 1]. of the couplerhead is free to move between the rollers 43 and the roller 49 only within certain limits, this movement being sufficient to compensate for the recoil of the coupler-heads when the cars are coupled and to permit said couplerheads to move slightly in their supports when the train is being started, and also to allow for the free movement of the coupler-heads when the train is in motion.

The lever 46 is supported by inwardly-directed shoulders or projections 54 on the opposite sides of the casing 40, which enter corresponding cavities or recesses in the bottom of the head 47 of the lever 4G, and it will be understood that the coupler-heads connected with each end of each car are of the same form and construction, and the movable jaws 10 of the coupler-heads at each end of the car are,when said cars are not coupled, held in the position shown in dotted lines in Fig. 4 by the springs 32, and whenever it is desired to couple the cars the shafts 35 are turned for- IOO ITO

wardly or outwardly and the cars are then run together in the usual manner and the movable jaws of the adjacent couplers interlock, and said movable jaws lO cause the rearwardly-directed arms 16 to rotate or move backwardly, and the cam-shaped heads 19 are forced under the heads 27 of the sliding bars 26 and cause the movable jaws 10 to interlock, as hereinbefore described, when they will occupy the position shown in full lines in Figs. l, 4, and 5, and it will be apparent that the shaft 35 may be operated from the top of the car, if desired.

My improved coupler is simple in construction and operation and is well adapted to accomplish the result for which it is intended, and it will be apparent that changes in and modiiications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, l claim as new and desire to secure by Letters Patentl. In a car-coupler, a knuckle pivotally mounted in the stationary jaw of a draw-head, a curved arm secured thereto and provided with a projecting arm having a cam-shaped shoulder or projection formed therein, a locking-lever mounted in said draw-head and adapted to engage said cam-shaped shoulder or projection, and a plate mounted on said knuckle and projecting over said cam-shaped shoulder and the outer end of said lookinglever, and means for operating the knuckle for the purpose set forth.
