HENRY MONROE MARQUELL, OF ALBANY, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 516,607, dated March 13, 1894. Application filed June 9,1893- Serial No. 477,043. (No model.)

.To a/ZZ whom t may concern:

Be it known that I, HENRY MONROE MAR- QUELL, a citizen of the United States of America, residing at Albany, in the county of Delaware and State of Indiana, haveinvented certain new and useful Improvements in Car- Couplings, of which the following is a specilication, reference being had therein to the accompanying drawings.

My invention is an improved car-coupler, and is designed to provide for the automatic coupling of the cars, and also for the uncoupling of the same without requiring the brakeman to present himself to any danger ofinjury from beingcrushed between the cars.

The invention includes a draw-head with a way therein for the link, a pivoted pin adapted to engage the link, and means operating the pin from a position to one side of or above the car so as to release the link.

In the accompanying drawings, Figure lis a side elevation of the end of a railway ear, embodying my invention. Fig. 2?- is a sectional view through the draw-head. Fig. 3- is an elevation ofthe draw-head showing the way for the link.

In the figures, A represents the car and B, the draw-head. This draw-head is made of box form, and is provided on its interior bottom surface with a way 5 which may be formed by two guide pieces with inwardly extending flanges with a space between for the movement of the pin. The link lits snugly in theway or groove thus formed, and the pin is adapted to move in the space between the guides, the end thereof passing through an opening in the bottom of the draw-head, and finds a bearing against the front ,wall of this opening. The link as shown at c is preferably elongated, and is made so in order that it may be disengaged from the pin by swinging the pin to the rear. The

pin is shown at C, and is pivoted at its lower end in the top plate of the drawheadso that it may be swung toward the front, lthus giving reverse movement to its lower end, and freeing it from engagement with the link, as the pin llas free movement toward the rear,-but is limited in its movement toward the front.

In order to couple the cars, it is only nec .essary to bring the oars together, and as the end of the link enters the groove or way formed to receive it, it pushes the end of the pin tothe rear until the link passes under the link of said pin, at which time the link assu mesits vertical position again bygravity, and thus when the cars are slightly separated again, the link is engaged by the pin, and the cars are finally coupled as the end of the pin nds a rigid bearing against the end of the recess or opening in the bottom of the drawhead. While I prefer to use the guide or way 5 for the link, it will be understood, that where cars of different heights are coupled together, it is not essential that the link shall be directed into this guide or way, but simply that it engages with the pin in any part of its length.

In order to readily uncouple the cars without requiring the presence of the brakeman in a dangerous position, I provide a lever f,

operating either the side or top lever after` the cars have been brought together to throw the ends of the link to the rear of the draw-head, the'forked lever presses upon the inclined end of the pin, which throws the lower end to the rear above the level of the link, and thus allows the link to be withdrawn.

Having thus described my invention, what I claim is l. A car coupling consisting of a drawhead, a guide or way in the bottom thereof, adapted to receive a link, a pivoted pin having free movement rearwardly, and a shoulderfor limiting its movement to the front, substantially as described.

2. In combination with a drawhead, a link adapted thereto, a pin pivoted therein, with its lower end freely movable toward the rear, and its upper end extending above the pivot, a stop for limiting the forward movement of the lower end, a rod having a forked end adapted to bear against said upper end, and rod connections from said forked end to the sides and top of the car for operating the same to swing the pin, substantially as described. ro

In testimony whereof I affix my signaturein presence of two witnesses.
