IMI-ROVED RAILWAY-CAR COUPLING.

Specification .forming part of Letters Patent No. 107,008, dated September 6, 1870 antedated July 15, 1.870

I, RENSSELAEE A, COWELL, of Cleveland, 1n the countyof Cuyahoga and State of Ohio,

have invented certain Improvements in Caror bumper, formailwaycars, having suitable open spaces cast in the head for the reception of thelink b,conp1ingpin c, and pallet d. The space or chamber a, in which the pin c plays,

is as long as the pin, and isl provided with a shoulder, c', upon which the head vof the pin rests, and below which it cannot pass. The top .ot the chamber a is covered with a cap, e, secured by a small bolt 'and nut, f. vThe cap c has a hole, b', through which a rod or chain, g, passes, attached to the eye of the pin. The cap e prevents the pin being withdrawn from lts chamber a, and, consequently cannot be misplaced or lost. Thepallet d is pivoted at d', and is operated by the link b. B is a rubber spring, through which the link bis passed,

leaving a suicient portion of the link projecting at either end to enter the draw-head.

The face of the draw-head against which the spring B bears is not made as `flaring as it usually is' in the ordinary draw-head, in order -to give the spring a better bearing, the linkentering just sufficient to allow the pin to drop through it into place. The link, when placed in one draw-head, by this means is held in a horizontal position, and is always readyfand easily enters the opposite draw-head. v

A coil spring of steel, embracing the link b, s

may be used instead of the rubber, or an elli-ptic spring may bev used instead of therubber, for the same purpose, but I prefer the rubber, for the reason that it is simpler, more readily applied, and not liable to be broken or to get out of order. l

The use ofthe spring B is to keep the drawheads spread to the extent of the link, and to take up the jarring by the concussion of cars, thus rendering a train devoid of the annoyance of sudden jerking and jarring in starting and stopping trains. The spring yields sufficiently for cars running on a curve, and will also prevent cars jumpingthe track.

When the cars are to. be uncoupled, the 'pin cv is raised in'its chamber a, and as soon as the .lin-k is withdrawn, the pallet d falls, and the pin rests upon it, ready to'be again coupled. The link, raising the pallet, lets the pin fall into place It will be seen that the chamberqc', in the lower side ofthe drawhead, is turned back slightly in its downward direction.l This is to prevent the pin being worked u-p by the link drawing upon it.

I am aware thatthe pallet for holding the pin upis not'new; therefore, I do not claim it.

Thiscar-couplingis particularly adapted to passenger-cars. A What I'desire" to secure by Letters Patent 1s 1. The -opening; a', when made at an angle to the passage a,as shown, to receive the coupling-pin and p revent its working up, as

. set forth.

2. The combination and arrangement of the drawlhead A, inclined passages a and 1t/,pin c, shoulder c', cap e, rod or chain g, and the pivoted pallet d, all constructed and operating asherein described.

E. n. eoWELL.
