BROOKS BUSH, OF ATLANTA, GEORGIA.

CAR-COUPLING.

SPECIFICATEON forming part of Letters Patent No. 394,909, dated December 18, 1888.

Application filed August 24, 1888. Serial No. 283,679. (No model.)

To all whom t may concern:

Be it known that I, BROOKS BUSH, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Car-Coupling; and I do hereby declare the following to be a full, clear, and exact description of the inven It consists of a draw-head containing a latch and mechanism to operate it connected to the outer corners of the car, an arrow-head bolt, and means of coupling with an ordinary link, the particulars of which will be hereinafter fully set forth and the parts thought to be new pointed out in the claims.

In the accompanying' drawings, Figure l is a cross-section on the line, Fig'. 2, showing' the interior of the draw-head and most of the operative parts. Fig. 2 is a longitudinal vertical section through the draw-head on the line y, Fig. l, showing the details shown in that figure and the arrow-head bolt. Fig'. 3 is a front view of the draw-head, not showing' the arrow-head bolt, but showing thel opening' into which it goes. Fig'. ai is a top view or plan of the draw-head, showing the arrow-head bolt and the sliding' catch by which it is secured and the lever by which the sliding' catch is operated. Fig'. 5 is a perspective of the device and the means of attaching' it, and the chains by which it is operated, to a car. Fig. t is a section on the line 5, Fig. 3, further showing the construction of the sliding catch.

In the several figures, like reference-marks referring to corresponding parts in the several views, A is a draw-head of any approved construction, except that it must be adapted to contain the operative parts hereinafter described-that is to say, the sliding' catch B, the shafts C, the arrow-head bolt D, the

opening E, and pin F. The bolt D (shown in Figs. 2 and 5) has a flange, CZ, in the center, to prevent the bolt entering the draw-head beyond the required distance, and the arrowheads d on the ends. This bolt, being in one draw -head, as shown in those iigures, is caused to enter an approaching draw-head by the conical concavity in the front of the draw-head, as shown in Figs. 3 and 6 and by the dotted lines in Fig. 2. From the bottom of this conical conoavity is an opening in the interior of the draw-head, of a slightly greater size than the arrow-head on the bolt D, which hole passes not only through the front of the draw-head, but also through the sliding catch B. The sliding' catch B is recessed on its back side, as shown in Fig. 6, to make a face level with that of the inner side of the drawhead for the shoulder of the bolt-head to bear on. The top side of the hole through this sliding' catch is beveled, as shown in Figs. 3 ando and by dotted lines in Fig'. 2, and it is obvious that the arrow-head on entering will raise the catch and pass through, when the sliding catch will fall, partly by gravity and partly by the force of the springs G, Figs. l and 2.

The two draw-heads working together should be alike in all respects, and, with the arrow-head bolt in one of them, the operation just described is that of coupling' them. To uncouple them, the operation consists in raising the catch B, which is done by the levers H and the key J. The shafts C are pivoted in the draw-head, the preferable manner being by the blocks K and L, and have on their forward ends cranks 7i, on which are rollers 7L', and in their middle portions the upwardlyprojecting double cranks H. These double cranks cross each other, as shown in Figs. 1 and 2, and the key J, having bearings in the top and bottom ot' the draw-head, passes between them. It is obvious that .the pressing apart of the upwardly-projecting cranks will raise the cranks 7L and with them the sliding catch B and release the arrow-head bolt, and that the turning of the key J will accomplish this result. At the top of the shaft j of the key J is a lever, M, which should extend in the direction of the face of the draw-head and be provided with an eye, mi, as shown in IOO Figs. 1, 2, and 5i. To the eye ym are attached the Chains N, that extend to a peint at or near the side et the ear, as shown in Fig'. 5, and have a sullieient slaekness to permit the lever M te swing' the required distance in either direction to turn the key and raise the sliding;l eaieh, as above deserihed. To prevent the key turning farther than is necessary to raise the catch te the required height, the abutting-pieces l proj eet inwardly treni the sides of the draw-heaifl, against which the cranks ll ahnt.

To Couple with the ordinary link, it passed into the opening' E at the top of the draw-head and Afastened hy the pin l, the parts havingr prolmrtions aeeori'lingl io the strength ol' the metal l'rom whiell lhe drawhead is made.

Having,r thus described my invenl ion, what I claim as new, and desire to seeurehy Leti ers Patent elf the ll'nited States, is

l. lu a ear-eounling', the draw-hezul, the eraiikm'l shalts, the sliding' eateh, aud arrowhead holt l), iu combination with the releasing' devices Consistingl ol the vertical sha'lt provided with a lever, )1, and key .'l, and the chains N, extending lirom said lever to points near the sides of the ear, substantially as i shown and deserihef'l.

BROOKS BUSH.
