FREDERICK O'IT, OF ESTRELLA, CALIFORNIA.

CAR=COU PLING.

SPECIFICATION forming part of Letters Patent No. 395,072, dated December 25, 1888.

Application filed June 27, 1888- Serial No. 278,344. (No model.)

To all whom, it may concern.-

zen of the United States, residing at Estrella, in the county of San Luis Obispo and State of California, have invented a new and useful Improvement in Car-Couplings, of which the following is a specification.

The invention relates to improvements in car-couplers; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

Figure 1 of the drawings represents a perspective View of the end of a car with a coupler embodying the invention attached. 2 represents a plan view of one of the drawheads detached, with the coupling-pin and the frame thereof removed to more clearly show the spring-controlled pin-detent. Fig. 3 represents a central vertical longitudinal section of one of the draw-heads. Fig. 4 represents a face or front View of one of the draw-heads.

Referring to the drawings by letter, Ardesignates the end of a car having the draw-bar, to which the recessed draw-head B is attached in the usual manner.

C is a frame standing vertically from the draw-head, near the outer end thereof, and composed of the side arms, 0 c, and the transverse bearing-bars c 0 respectively, which connect the said arms above the draw-head.

I) is the coupling-pin, which is much longer than in the ordinary style of coupler, and which passes down through the bearin in the bars 0 c and into the pin-openings d in the roof and floor of the draw-head. The inner edges of the arms 0 enter the vertical grooves d in the i sides of the d aw-head, and the lower ends of said arms are reduced and shouldered, as at (Z the slotted bar (I being secured on fcoming detached, either upward or down- Be it known that I, FREDERICK OTT, a citi- I ward.

e is an opening through the coupling-pin, and e is a pin that can be passed through said opening above the upper bearing-bar, c,-

the said pin being connected to the frame C by a cord, F is a detent-plate having the similar trans- 3 verse arms f lying upon the upper surface of the draw-head, which arms are bent downa ward over the sides thereof, where they have Fig. 5

the lateral frontward proj ections, f provided with the vertical buffer end plates, f The said projections f pass through the notches f on the inner edges of the arms 0. The said plate has a forwardly-standing arm, G, that passes under the point of the coupling-pin D when the same is raised, and a rearwardly-standing arm, H, provided with a longitudinal slot, 71, through which the T-shaped pin or bolt I passes, the lateral projections of which overlie the said arni H and hold the detent-plate down on the draw-head. The rear end of the arm H is bent upward andconnected to the lower bearing-bar, 0 by the coiled spring 2', which I forces the detent-arm G under the point of the said ends by the pins (1, that pass through I suitable openings in said bar. The frame C thus has its lower bearing-bar, 0 on top of the draw-head, and its connecting-bar d below the same. The coupling-pin passes up centrally through the space E, between the bearing-bars c 0 and has passed through a longitudinal slot, at a proper point in its length, the stop 6, which, by bearing on the bars 0 c prevent the coupling-pin from becoupling-pin when the latter is raised.

J is the link having the central double bend,

j, by means of which draw-heads of unequal height may be coupled. The said bend permits the ends of the link to stand parallel to each other at different elevations.

K is a spring-rod,with its rear end secured to the outer surface of the floor of the drawhead and with its front portion bent upward through an opening, 7.", in the draw-head in rear of the lower pin-opening, and formed within the draw-head into a rearwardly-projecting hook, in, which engages over the end of the link within the draw-head and holds the link in position to engage.

If desired, a perfectly straight link maybe substituted for the link bent as described.

\Vhen the brakeman on top of the car lifts the coupling-pin, the detent-arm G is forced thereunder by the coiled spring i, and the pin is thereby upheld till the bufter-platesf of the opposing draw-heads strike together,driving back the detent-plate against the action of the spring 27 and permitting the couplingpin to fall. \Vhen the buffer-plates are driven completely inward, they enter recesses in the IOO end of the draw-head and are thereby prevented from breakage.

By means of the pin 6 and opening a the coupling-pin can be held up and not allowed to engage the link.

Haring deseribed my invention, l elain1 1. The combination of the drzuv-head havin g an opening, 7;, in, its bottom, and the spring K, passing through the openiu k and having one end permanently secured. to the under side of the draw-head and its other end bent 1 to the frame C and the detent-plate, as set forth.

3. The eon'ibination, with the (hraw-head, the vertical :t'ra-me, and the coupling-pin, of the detent-plate having the (letent-arm G and the slotted arm Ii, the pin or bolt 1, the coiled spring 1', and the bufier-plates f" on the lateral extensions 01? the detent-plate, subsiantiall y as speeifi ed.

4-. in a eair-eoiqiler, the eoinbinalion, with the recessed draw-heat'l and the link, of the spriugro(l K, having the rearwm'dly-standing hook it on its end within the drmr-luad, subst-antiall y as specified.

In testimony that-I claim the [foregoing as my own I have hereto aftixed mysignature in presence of two witnesses.
