\ CAR-COUPLING.

' SPECIFICATION forming part of Letters Patent No. 341,492, dated May 1l, 1886.

Application filed March 16, 1836. Serial No. 195,441. (No model.)

fr) all whom it may 0012.061172'.-

Be it known that I, JOHN CHARLES FRE- MONT McGAULEY,a citizen of the United States, residing at Crooked Creek, in the county of Ford and State of Kansas, have invented a new and useful Improvement in Gar- Oouplings, of which the following is a speciiication, reference being had to the accompanying drawings.

My invention relates to an improvement in car-couplings; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

Figure l is a perspective view of inyinveution. Fig. 2 is `a side elevation ot' the saine. Fig. 8 is an inverted plan view. Fig. 4 is a detail sectional view taken on the line a: x of Fig. 3. Fig. 5 is a horizontal sectional View. Figs. 6 and 7 are detail perspective views of the arms e and b, respectively.

This invention is an improvement on the Y car-coupling described in my application for Letters Patent of the United States, Serial No. 187,867, filed November 14, 1885.

A represents the draw-head,'which is provided on one side with the vertically-extending mouth B, and which has the central opening, C, for the usual couplinglink, and the laterally-projecting ears D,which extend from the draw-head on the side opposite the mouth B lower projecting spindle of which is a coiled spring, F, one end of the said spring being attached in the side of the opening made to receive the spindle, and the other end thereof engaging with an arm, G, which is secured on the lower end of the spindle. This spring keeps the detent normally in the position shown in Fig. 5.

In between the ears D is pivoted acouplinghook, II-sueh as described in my application before referred to-the said hook being adapted to enter the month B of the opposing` coupling and to engage with the springactuated pivoted detent therein.

On the under side of the mouth B is secured a casting, I, having rearward-extending di' verging arms K, at the inner ends of which i said arm, as previouslydeseribed,) thedetent 10o In the mouth B is hinged a detent, E, on the tending arms connected to the link N byV means of rods R.

S represents a rock-shaft having its ends bent downwardly to form arms S', the said,

rock-shaft being jonrnaled in horizontal aligned openings that are made in the lower; end of the ears L, and to the said shaft isy firmly attached a pawl, T, which is adapted to engage the opening n of the link when the latter is moved rearwardly, and the rock-shaft is turned upwardly by means of the mechanism to be hereinafter described.

U and U represent rods, which have their inner ends attached to tlierear extending ends of the bell-crank levers by lneans of universal joint-s u. The said -rods are also provided neartheir. inner ends with arms n', which extend at right angles from therods, and are connected to the arms S' of the rock-shaft S by meansof chains n2. The outer ends of the rods U and U are bent to forni handles, as shown, andthe outer end of the rod U is suspended from the front end of the car by means of a cord or strap, V.

Vhen cars provided with my improved form of coupling come together,the couplinghook H of one coupling enters the mouth B ofthe other and engages with the spriugactuated detent E therein, and the cars are thus coupled together,automatically and without the necessity of abrakeinan going between the cars and endangering life' or limb. By drawing either ofthe rods U or U outwardly from the side of the car, (the said rods being connected to the spring-actuated pivoted detent by means of the bell-crank levers, the slidinglink, the arm G, and the chain connecting the link with the is moved yinwardly in the position shown in dotted lines in Fig. 5, and releases the coupling-hook and thus nncouples the car. Vhen it is desired to maintain the detent in this position and thus permit two cars to come together without coupling, as is frequently the case when cars are switched onto or from a siding, the rods U and U, when being drawn outwardly to their full extent, are also turned through about quarter of a circle, causing their arms u to move rearwardly, and thus draw upwardly on the arms S' of the rockshaft, which carries the pawl, and thus causes the pawl to engage with the notch n of the link, thus holding the detent iirmly in a closed posit-ion.

In Fig. 1v I illustrateamechanism by meansA of which the cars maybe uncoupledbya person on top of one of them.

the car near one side thereof, and between the saidl keeper andthe end of the car is pivoted an arm, b, the upperv end ot' which is bifurcated, forming a recess or slot, b', and the lower endot` the said'arm is attached to the rod'U by means of a universaljoint, c. An arm, d, is secured to the said rod near the outer end of the latter. e represents'a lever-arm, which is pivoted in the upper end of the arm b by means of the boltf, which forms thefulcrum for the said arn'nand thelever-arm chas at its inner end a depending arm, e', which bears against theinnerside of the arm b. To the outer end of the lever-arm c is attached a verti cal rod, g, by means of a universal joint, g', and the 'said rod g is guided by means of a keeper, l1., on the front endof the car, and extends to the'upper side thereof. VNear the lower end of the rod g is an arm, g2. 7c represents abellcrank lever, which isfulcrumed on the outer endof the pivotal bolt j'. One arm of this lever is connected to the arm Z of the rod U by means of a chain, 7c', and the other arm of' the said bell crank lever is connected to the arm g2 of the rod g by means of a chain, It?. By drawing upwardly upon the rod g the arm U may be drawn outwardly, and thereby canse the detent E to be swung inwardly in Vthe'draw-head to release the couplinghook,

a representsaA keeper, which is secured on the front end of' and by turning the said` rod g outwardly through a quarter of a circle, the rod U (being connected thereto by 1n cans ot' the bell-crank lever and the chains, as hereinbefore described) is caused to partly rotate, thereby causing the pawl vto engage with the notch in the link N,

Yas liereinbefore described, thus enabling the car-coupling to be operated by a person on the top of one of the cars.

Having thus described my invention, vI claim- 1; rIhe combination, with the draw-head, having the spring-actuated pivoted detent, of the bel1-crank lever connected to the said detent, and the rr. ds U and U/, attached to the said bell-crank levers, whereby the detent may :be moved inwardly against the side ofthe draw-head by drawing outwardly upon either of the rods U and U', substantially as described.

2. In a earl-coupling, the combination of the draw-head having the spring-actuated dee tent, the bell-crank lever, the rods connected thereto, the link attached to the detent, and

having the-notch or stop, and the pawl having` 'the arms S', connected with the rods U and U,

whereby the detent may be swung inwardly by drawing outwardly on the rods U and U, and locked in that position by partly rotating either of the said rods, to cause the pawl to engage with the notch or stop on the link, for the purpose set forth, substantially as de scribed.

3. The combination, in a car-coupling, of

Vthe endwiseinoving rod U', for tripping the
