' vcAR-couPinsca SPECIFICATION forming part of Letters Patent No. 269,106, dated December 12, 1882.

` Appnaeion n1edAugust2s, 1882. (No model.)

To all whom 'it may concern Be it known that we, JOHN G. PEACE and EBEN B. SANKEY, both of Salem,in the county ofDent and State ot' Missouri, have invented a certain new and nset'ul Improvement in Car- Gonplings, o t' which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical section taken on line 1 l, Fig. 2, showing themadjoining ends of two car-bodies Vin outline. Fig. 2 is a top View of two draw-heads, with parts otonebroken away to show the parts inclosed in top view. Fig. 3 is an end view. Fig. 4t is a transverse vertical section taken on line 4 4, Fig. l; and Fig. 5 is a similar view taken on line 5 5, Fig. 1. Fig. G is a detail top view ot' the rock-shaft and lever for raising the coupling-pins. Fig.

7 shows an end view and a side view of the- Sliding blocks within the drawheads.

Ourinvention relates to a car-conpling which is automatic in its operation; and our invention consists in points of novelty hereinafter Jr'ull y described and claimed.

A represents the adjoiningends of two cars, The draw-heads are connected tothe car-bodies in the ordinary manner, except the connecting-bolts B securing their inner ends, insteadof being rigidly secured to them, connect with a badanti-socket joint, as shown in Fig. l, which better allows the vertical movement ot their outer ends.

The parts on the respective cars are dupli- Cates, so in describing our invention it will only be necessary to refer to the parts ot' one' ot them.

C represents the coupling-pin, to the upper inward-projecting end,U/, of whichis connected a hoisting-chain, D, the other end of the chain connecting with the outer end of a horizontal arm or lever, E. rlhe inner part ofthe upper portion of the pin-opening in the draw-head inclines back,formingan eIV1largement,F,which does not extend quite to thethroat ot' thedraw-` head, thus forming -a projection, F', against which the lower endofthe pin rests at certain times, as hereinafter described. 1t will be seen that when the pin is raised by the chain its lower end will swing into this enlargement. F, as shown by dotted lines, Fig. l, and

can be raised either from the top of the car or from either side, in the former case by means ot' a chain, G, connecting with the outer end ofthe arm or lever E byits lower end, and its upper end connecting with the lower end of a pull-rod, G', secured to the end of the car by brackets G2 beneath the foot'board, and in the latter case by means of a rock-shaft, G3, secured to the end of the car by journal-brackets G4, to which ,the inner end of the arm E is secured. G5 are cranks on the ends. of the rock-shaft, by which :it can be turned. The

lugs G5, projecting outward from the shaft, be` tween which the arm'is pivoted by means ot' a pin, G". On the lower part of the arm is a projection, E', which extends beneath the rockshaft. Now, it will be seen that when the shaft is turned the outer end ot' the arm will be raised, but when the arm is raised from the top of the car the shaft remains at rest, so that the unnecessary power required to raise it is avoided. A is a stop, secured tothe end of the car, against which one or both of' the lugs VG6 strike to prevent the arm E being raised too high from the side of the car.

H is a sliding block Iitting in the throat of the draw-head, and having on its innerend a stem or reduced portion, H', which receives one end of a spiral spring, I, secured to it by a transverse pin, H2, the other end of which is connected in the same manner with the outer end of a stationary block, J, held in place by a set-screw, J', passing through from the outside ofthe draw-head. The slidingblock pret'- erably has feet H3, which support it, and in its upper portion is a hole or inortise, which receiygesajreyhml, inserted thron gh the pin-opening aftermthblock has been placed in the throat. The keyprojects up from the top ot' the block and works in a longitudinal groove, B2, in the upper part of the throat ot thedrawhead, passing through the projection F.

The operation ofthe coupling is as follows: .Supposing the cars to be coupled, as shown on the letthand side ofFig. 1,tl1e pin is raised, as described, and as soon as its lower end has Yreached the enlargement F it will assume the arm is connected to the rocklshaft by means of Q A nemico position shown by dotted lines and be supported there. Then when the coupling-link L `is withdrawn the sliding block will be forced forward by the spring, the key striking the lower end of thecoupling-pin, removing itfrom the projection F and causing it to assume aiv vertical position, in which it is supported by the outer endof the sliding block, as shown on the right-hand side ot' Fig. l. Then when the coupling-link enters theinouth of thedruwhead as the cars come together to be coupled,

it strikes the sliding block and moves itin- Ward from under the pin, which then gravitates, and the coupling takes place.

It will be seen that 'acar with our automatic coupling applied will connect with another having the old form of coupling as readily as it will'with one ofits own kind.

If desired, the pin-hole may have u. straight back, the top of the hole being considerably larger than the pin.

We claim as our invention--V l. In combination with a. draw-head having an' enlargement, F, at; rear of middle part of upper portion of the pin-hole, forming proz5' JOHN G. PEACE. EBEN B. SANKEY.
