SPECIFICATION forming part of Letters Patent; No. 383,424, dated May 22,1888.

Application iiled November B, 1887. Serial No. 254,192. (No model.)

To all whom it may concern:

Be it known that I, Emir RonnRTsoN Yan GER, a citizen of the United States, residing at Rockwood, in the county of Roane and State of Tennessee, have invented new and useful Im provenients in Oar-Couplings, of which the following is a specification.

My invention relates to improvements in car-couplings; and it consistsin a certain novel construction and arrangement of devices, fully described hereinafter, and specicall y pointed out in the claims.

The improved coupler is illustrated in the accompanying drawings, wherein- Figure l is a perspective view ofthe end of Fig. 2 is a longitudinal section. Fig. 3 is a front view. Fig. e is a transverse section on line ma, Fig. 2.

Referring by letter to the drawings, A designates the body of the draw-head, having the liared mouth B, and the interior of the drawhead is out out or recessed to forni the guideslot C. The follower D operates in this slot, and is preferably square in section, having a round extension, D, at the rear end, on which is disposed the coiled spring E. The said spring bears at one end against the shoulder d, which is formed at the rear end of the squared portion of the follower, and at the other end against the rigid plate F, which is secured transversely across the body of the draw-head near the rear end'. The plate F is provided at the center with an opening or bearing, f, in which operates the rear end of the rounded extension D'. On the upper side ofthe square portion of the said follower is secured a leaf-spring, G, which presses at the free end against the upper side of the recess or slot C. A shoulder, g, is formed on the upper side of the recess C near the front end, in the path of the free end of the said spring, and it will be seen that the forward motion of the follower will be limited by this shoulder, as the front or free end of the spring cannot pass beyond the same. The front end of the follower is beveled downward and rearward and provided at the lower edge with a shallow recess, H, of sufficient size to receive the end of the link I. Theshoulder, h, thus provided (namely, by the recess H) bears on the upper side of the rear end of the link, and as the spring Gr on der the front end of the follower is slightly inclined or beveled rearward and downward, as seen at h', so that when the front end of the follower presses down upon the rear end of the link, as hereinbefore described, the outer end of the link will be held slightly inclined upward, as clearly seen in the drawings.

As before described, the mouth of the drawhead is flared outwardly, and, consequently, when a link is engaged in a draw-head, it will be capable of considerable lateral swing at the outer end around the pin.

The coupling-pin K is secured or received in vertically-aligned openings k 7c in the upper and lower sides of the draw-head.

The front end of the follower is adapted, when the coupling-link is not in place and the pin is raised, to be projected by the force of its actuating-spring under the opening k, which is formed in the upper side of the drawhead, thus preventing the pin from dropping across the opening in the draw-head prennan turely. When thelink carried by an' approaching car is inserted into the draw-head, it strikes uponthe beveled frontend ofthe followerD, and

' is guided by the formation thereof to the recess H, where, being enabled to press directly against the force of the spring E, the follower is depressed or forced back, and the couplingpin is allowed to fall and complete the coup ling by engaging the link.

The upper end of the coupling-pin is provided with a ring, L, in which is secured the lower end of the chain L', and the upper end of the latter is attached to a horizontally-projecting arm, M, which forms part of a vertical uncouplingrod, Ne The said rod N is adapted to operate vertically in guides u u, which are secured to the end of the car or other suitable support, and the upper end of the rod is provided with a ring or suitable handle, O. This rod extends, as shown in the drawings, to the top of the car, within easy reach of the trainhands, and to uncouple the cars it is simply necessary to raise the said rod.

ICU

P designates a small stop or stud, which is secured to the end of the car in such a position that when the uncoupling-rod is raised it may be turned to cause its horizontal arm M to engage the said stop and maintain the pin in the elevated position. The object of this is to enable the pin to be locked in the elevated position when it is desired to prevent the coupling being made.

The unooupling device which I provide is simple, and the operation of the coupler both in coupling and uncoupling is exceedingly direct and reliable, there being no danger of any of the parts failing to operate in the intended and proper manner. Also, the means which I provide for holding the link in the proper position to couple with an approaching car is a great improvement.

Having thus described my invention, I claiml. In a car-coupling, the combination, with the draw-head A, of the spring-actuated follower D, operating therein and having a shoulder, 7a, on the front end, the pressure-spring G on the upper side of the follower and bearing against the uppei` side of the opening in the draw-head, and the link adapted to be engaged at the rear end under the shoulder h, as and for the purpose hereinbefore specified.

2. In a car-coupling, the combination, with the draw-head having a recess or slot, C, therein, provided at the front end on the lower side with an upwardly and outwardly beveled portion, h', of the springactuated follower D, operatinginthe recess C,audhavingashoulder, h, on the front end to pass over the couplinglink, and the spring G on the upper side of the follower, adapted to press the front end of the same down to hold the end of the link depressed, substantially as and for the purpose specified.

3. In a car-coupling, the combination, with the draw-head having a recess or slot, C, therein, and the shoulder g on the upper side of the said recess at the front end, of the spring-actuated follower D in the draw-head, having the leaf-spring G on the upper side to bear against the upper side ofthe recess C and engage the shoulder g, to limit the forward motion of the follower, all arranged substantially as specified.

4. In a car-coupling, the combination, with draw-head A, ofthe coupling-pin K, the vertically-movable uncoupling-rod N, having the horizontal arm M, the chain or other flexible connection between the said pin and the horiv zontal arm lVI, and the stud or stop P on the end of the car, adapted to be engaged by the said horizontal arm when the coupling-pin is elevated, substantially as specied.

5. In a car-coupling, the combination, with the recessed draw-head having a shoulder, g, of the follower operating in the draw-head and carrying a sp1-ing which bears against the said shoulder when the follower is in its extended position, substantially as specified.

In testimony thatI claim the foregoing as my own Ihave hereto affixed my signature in presence of two witnesses.
