UNITED STATES PATENT sIMoN .I. KEIM, on OATASAUQUA, PENNSYLVANIA, AssIeNoR OF ONE- HALF HIS RIGHT TO WILLIAM YOUNGER, or SAME PLACE.
IMPROVEMENT IN CAR-COUPLINGS.
Specification forming part of Letters Patent No. 200,311, dated February 12, 1878; application filed March 27, 1877.
To all whom it may concern:
Be it known that I, SIMON J. KEIM, of Catasauqua, Lehigh county, Pennsylvania, have invented a new and useful Improvement in Oar-Coupling, which improvement is fully set forth in the following specification and accompanying drawing, in which- Figure-l is a plan. Fig. 2 is a side elevation. Fig. 3is a longitudinal section. Fig. 4 is a front-end view.
The object of my invention is to make the railway-cars self-coupling, so that by simply pushing the cars in contact they will become securely fastened without any assistance from the brakeman.
A is the draw-head; B, the buffer; G, the draw bar. The draw-head is made double, having an upper recess, a, and a lower recess, a or there may be several recesses, so that in the event of two cars coming together having draw-heads of difierent heights there will be no difficulty in coupling them.
A falling bolt or tongue, 0, is pivoted to the shaft e, which passes] through the draw-head above the recess a and a similar bolt, 6', is
pivoted to the shaft 0 which passes through the middle web of the draw-head. Each of these shafts has a lever-arm attached. (Shown in Fig. 2, and lettered h h These arms are connected on the outside by a link, K, which is weighted at the bottom by a ball, M, or the link itself may be heavy enough to act as a weight. An eye, k, is made at the top of the link, into which a chain may be hooked, and the bolt or tongue operated from the platform of the car.
The bolt 6 is held vertically in the position shown by the weighted levers, and as soon as the cars are forced together for coupling the end of the draw-bar. O forces the bolt 6 into its recess d, and as soon .as it has passed the bolt falls and the pull of the draw-bar brings the toe of it in contact with the stop m on the lower side of the recess a. The operation of the upper and lower bolts 0 c is the same, and the movement of one is communicated by the link K to the other. forced into the recess d the lever h takes the position shown by dotted lines, Fig. 2.
The buffer B is made with two funnel-shaped mouths, corresponding with the recesses a a and the central web is pointed at g, so as to facilitate the entrance of the draw-bar 0 into one or the other recess.
I claim- 1. The combination, in a draw-head, of a series of bolts pivoted on shafts one above the other, levers at the ends of said shafts, and a weighted link uniting said levers, substantially as and for the purposes specified.
2. The combination in the draw-head A of the two recesses a (t the falling bolts e 0 the stops m m on the lower side of the recesses, the levers h W, and the weighted link K connecting them, as herein described.
