RAILROAD-CAR COUPLING.

Specication of Letters Patent No. 23,282, dated March 15, 1859'.

To all wwm-t may concern: Y

Be it known that We, NOAH H. W'ENT- woR'rH and MARTIN L. AMES, of the town or" Somersworth, in the county of Stafford and State of New Hampshire, have `invented a neiv and useful mprovement in Car-Couplings; and We do hereinT dee-lare that the following is a full and exact description of the same, reference being had to the accompanying drawings and to the letters and marks thereon.

Of the drawings forming part of this specication, Figure 1, represents the conpling in the condition for holding the cars together; Fig. 2, the condition when ready for being separated; and Fig. 3, shovvs one of the parts of the coupling only with the latch or catch inclined downward by the iorce of the spring.

Each part of this coupling is made up of a frame or case (n), having a latch or catch (Z2), a lever (c), a shaft (cl) to which is affixed the latch andthe lever, a crankarm (c) for operating the shaft (f) and two cams g, g), the one being under the latch and the other (9') being under the lever, and a spring (fr) for forcing the latch downward and holding it in position when the parte are coupled.

It will he seen that when both of` the parte of the coupling are aliixed to cars, the latch of the one part will, by the proper movement of the car being given, readiljT pass over the bar of the other part of y the coupling and catch and be held in its connecting position, provided the lever of the other part is depressed, and thus the catches of both parts of the coupling will hold the one to the other. Vvhenever it is desired to unconple, turning the crank-arm (e) will elevate the cams (g, g), the one cam acting directly on the latch or catch and the other cam acting indirectly through the lever. Under this arrangement both shafts become the means of operating on both latches, and `both levers act as guides to the latches as Well as levers. Each crank-arm (e) can he actuated independently or several of them may be operated conjointly by any convenient means for that purpose. This arrangement of the latches and levers With the cams and shafts makes a very sure and steady coupling.

Having thus set ont our invention vvhat We claim as newY and desire to secure by Letters Patent is,

Combining with each latch or catch a lever as herein described, and providing the latch and lever when thus combined With the cams and their shafts and crank-arms for actuating them, as and for the purposes set forth.
