CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 307,228, dated October 28, 188%.

Application tiled March 18, 1881i. (No model.)

To @ZZ `whom, t may conocia.

Be it known that I, EDWARD J. Ronilxn'rs, a citizen of the United States, residing at Ashland, in the county of Boyd and State of Kentucky, have invented certain new and useful Improvements in Car-Couplings, of which the following is a specication.

According to my present improvement the draw-bar of the caris preferably made hollow,

1o and Within the same is placed the link-retaining hook or pull-rod, strain on which is transmitted through the medium of a spiral spring directly to the frame or body of the ear, the draw-bar itself being employed merely as a buffer, transmitting rearward strain to the frame through themedium of the same spiral spring. The draw-bar or buffer is provided with a plate or block, against which the head of the pull- J'od is forced by a stout bar or plate spring.

2o Between this plate or block and the inclined face of the pull-rod the link is forced by theimpact of two cars, and, slipping past the notch or hook ofthe rod, is rmly held in place, the -rod being returned to contact with the plate or block by the springbefore referred to. An L- lever is pivoted at the forward end of thepullrod and arranged to be operated by hand directly or through tliemedium of alever, to elevate or depress the link when coupling, as

3o well as to force the hook away from its bearing-surface when it is desired to uneouple. The pull-rod is made adjustable by screw and nut on its rear end, and provided with a shoulder, between which shoulder and the end of the draw-bar a spring is interposed, Vserving the double purpose oftaking up slack motion between the pull-rod and buffer and of projecting or permitting the retraction of the pullrod, thus adj usting the position of the link to 4o effect a coupling under compression of the buffer-spring.

In order that my invention maybe fully understood, I will proceed to de-scribe it with reference to the accompanying drawings, iu

which- Figure I is a plan view of a car-couplin g embodying my invention. Fig. II is a vertical longitudinal section thereof. Fig. III` is an under side view of the same.

In a car-coupling constructed according to 5o n1 yimprovement the draft-link l is adaptedto be retained by the hook-shaped vend 2 of a pullrod or bar, (i, which transmits strain to draftplates 4 5, capable of forward and rearward movement, respectively, ina socket or yoke in the frame of the car. A draw-bar, 7 preferably of open construction, as here shown, is made hollow for the reception of the pull-rod or hook, and, having bearing at rear against plate 5, is adapted to act as a buffer, transmitoo ting strain through such plate and spring S to the plate l and frame of the car. It will be seen that both forward strain on the pull-rod and rearward pressure on the buffer will be transmitted through the medium of the plates 4 5 and spring S to the frame of the ear. Upon the forward end of the draw-bar or buffer is arranged a block or plate, 9, against which the lip ofthe hook 2 is made to bear by bar or plate spring 10. The front of the hook 2 is in- 7o clined, as shown, to direct the link and aid in depressing the hook for coupling. A forkedshaped L-lever, 1l, is fulcrumed to the hook 2,

g and, hanging down from the buffer, is adapted to be operated by hand or through any usual means for this purpose, either to raise and lower the link when coupling, or to force apart hook 2and block 9, to permit the pulling out of thelink when uncoupliug. Immediately on the pulling out of the link the L-lever l1 being re- 8o leased, the hook 2 is returned to position against the plate 9 by the spring l0. In Fig. III is shown a erankshaft,14, journaled in the drafttimbers, and adapted to be operated to work thelever 1l. rlhebearing ends of the L-lever S5 1l are preferably curved or beveled to allow itto move more freely over the link when operated.

l'n order to prevent any loose motion between buffer and pull-rod, a shoulder or fiange, 12, is 9o formed upon the latter, and a spiral spring, 13, placed between the same and the rear end of the buffer.' This spring serves also the still more important function of lengthening or permitting the shortening of the pull-rod accord-d ing to needto permit coupling to t-ake place in any condition of the buffer.

The amount of compression of spring S and ille relative position ol the buffer and the pull rod are regulated by means of nut or equivalent device adjustable on the inner end of' the pull-rod and bearing upon the plate 4.

The necessary traverse of the d raw-bar when turning curves is ai'iorded by the pressing` i'n of the bullers and pulling out ofthe rod 3,'thus compressing springI S from both ends, the bufl'er and rod being both automaticallx7 returned to position when the curve is passed.

It is evident that, if desired, the plate 5 may be discarded, the spring S in sueli. case bearing` directly against the rear end of the drawbar; but the arrangement here shown is preferred.

Haring thus described my invention, therfol lowing` is what I claim as new and desire to secure by Letters Patent:

I. The combination of draw-bar or buii'er 7, block 9 thereon, and spring rod or bar 2 (i, substantiallyas and l"oi"thepurposes set forth.

2. The draw-bar orbuft'er 7, having bearing block or plate 9, the spring pull rod or bar 2 6, and lever Il pivoted thereto, for the purposes setfortli.

3. In combination with draw-bar 7 and pullrod or hook 2 6, the L-shaped lever 11, pivoted to said hook and adapted to lift the link for couplin` with au opposing draw-bar, and to release the link for uneoupling, substantially as shown and described.

4. In combination with pull-rod 6 and lever 11, pivoted thereto, the crank-shaft 14, jour naled to the draft-timbers for operating suoli lever, substantially in the manner described.
