SPECIFICATION forming part of Letters Patent No. 420,540, dated February 4, 1890.

Application i'lled October 30, 1889. Serial No. 328,705. (No model.)

To all whom, it may con/cern.-

Beit known that we, JONATHAN HOLDEN KINGr and BENJIMAN FRANKLIN REED, citizens of the United States,.residing at Swan Creek, in the county of Warren and State of Illinois, have invented a newr and useful Car- Coupling, of which t-hefollowing is a specification.

Our invention relates to improvements in car-couplings; and it consists in certain novel features of construction, hereinafter described and claimed.

In the accompanying drawings, Figure l is a front view of a car-coupling provided with our improvement. Fig. 2 is a longitudinal section of the same. Fig. 3 is a transverse section on the line x x of Fig. 2, looking in the direction indicated by the arrow.

The draw-head A may be of anydesired size, and is of the usual or any preferred construction. At the front end of the drawhead on the sides of the same we erect the standards B, in the upper .ends of which We journal a rock-shaft C, having a cam-plate or crank-arm D at its center, to which we secure a chain E, carrying the coupling-pin F. The coupling-pin passes through the drawhea'd in the usual manner, and an ordinary coupling-link Gis inserted into the draw-head and engaged by the coupling-pin, as shown. On the upper side of the draw-head in rear of the standards B we secure or provide the brackets H, in which pivot-pins I are secured, and levers J are pivoted on said pins and eX- tend from the same over the top of the drawhead in contrary directions and project beyond the sides of the draw-head. The levers are provided in their lower edges with the notches or recesses K, so that each lever may fit over the pivot of the other lever, and thereby allow the levers to be depressed to their full extent, and the levers are raised by a 'spring L, which has its opposite ends secured to the lugs M on the upper edges of the levers, so that when the levers are depressed the spring will be extended, and when the pressure on thelevers is removed the spring will be constracted and draw the levers together, so that they will move upward. The forward lever is provided with a pivotpin N, which passes through a longitudinal slot O in the rear lever, so that the levers will be caused to operate simultaneously and will not bind togetherwhen in use. A pressure-plate P is pivotally mounted on the pin N, and depends therefrom through a transverse slot Q in the top of the draw-head, so as to bear on the inner end of the couplinglink and depress the same into a recess R in the floor of the draw-head.

From the foregoing description the operation and advantages of our improved coupling are thought to be obvious. Vhen it is desired to couple two cars together, the lin'k is secured manually in one draw-head, and the cars are then made to approach. As the cars come together the lever on either side is depressed, thereby pushingthe presser-plate onto the inner end of the link, so that the said end will be lowered and the outer end raised, and' thus effectually guided into the lopposing draw-head. When lthe coupling has been effected, the pressure on the lever is released, and the spring at once draws the upper portions of the levers together, so that the presser-plate will be raised and the links allowed to assume a horizontal position. IVhen it is desired to uncouple the cars, the rock-shaft will be rotated, thereby lifting the coupling-pin out of engagement with the link, so that the link may be withdrawn from the draw-head.

Our improved coupling is very simple, and by its use the coupling-link will be held in proper position at all times and positively guided into the draw-head..

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

l. The combination, with the draw-head, of

the levers-pivotally mounted on the upper side of the same near the opposite edges thereof, the presser-plate having a common pivotal connection with the levers and depending therefrom into the draw-head, and a spring secured on the upper edges of the levers and connecting the same, as set forth.

2. VThe co1nbination,with the draw-head, of the levers pivotally mounted on the upper sides of the same, and each provided with a notch or recess to engage the pivot of the our own Wehzwe hereto aixed oursglmt'ures other lever, the presser-plate having :L eemin presence of two witnesses.

mon pivotal connection with the levers and JONATHAN HOLDEN KING. depending therefrom info J[.he draw-head, and BENJIMAN FRANKLIN REED.

5 the spring secured to the upper edges of the Witnesses:

levers, as set forth. E. A. ROBERTS,
