' Letters Patent No. 84,049, dated November 17, 1868.

IMPROVE!) CAR-COUPLING. fl The Schedule referred to in these Letters Patent and making part of the same.

To all persons to 'whom these presents may come Be it known that I, JOHN H. GHADWICK, of Bristol, inthe county of Bristol, and State of Rhode Island,have invented an Improved Railway-Carriage Coupling; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is aside elevation,

Figure 2, a longitudinal section, and

Figure 3, a front elevation of a railway-carriage drawbar with my invention applied to it.

In such drawings, A denotes thedranbar, having within it a chamber, B, provided with a flaring mouth, C. The mouth, at its junction Ii with the chamber, is rectangular in shape, and the ont endof the chamber is a vertical plane.

b A 1passage or slot, c, leads out ofthe top of the cham- A lever, D, provided with two curved armsb c, extended from it in manner .as represented in fig. 2, is arranged within the chamber B, and projects out of the chamber, or through the slot a thereof, in manner as shown inithe said figure.

rllhe upper arm f of the lever has a weight, e, fastened to it, there being a staple, g, projected from the weight for the purpose of attaching a rope or a chain, h., to the Weight. A

The fulcrum d of the lever D is a pin going through the'lever and the two opposite sides of the chamber B.

'lhe draw or connection-rod E, used to eii'ect the coupling of two cars having draw-bars provided with a chamber and coupling-lever, made and arranged substantially as described, is' shown at E, it being furnished with two projections or shoulders l l, and two wedged v or'pointed rods k la, v formed and disposed as shown in vfig. 2. f

When the connection-ibex E, which projects from the draw-bar of one carriage isin the act of being moved toward and into the chamber ofthe draw-bar of another carriage, the forward nose k of the bar E will be forced against the lower end of the auxiliary arm c of the lever D, and will thereby move the lever on its fulcrum, so as to enable the nose k to pass into the circular space between the arms b c. The bar E continuing to advance, will move the arm b below the fulcrum (l, and consequently will move the lever 'in an opposite direction, and the bar E down, so that when next pulled back, such bar E will catch upon the part, "n, between the mouth c and the chamber B thereof, and thereby cii'ect the coupling of the bar E to the draw-bar.

The weight e, with the auxilliary arm c, serves tokeep the bar. E in connection with the part, nl.. On-

raising the weight and the arm f of the lever D, the arm b will be forced against the nose 1c of the bar E, so as to elevate the .shoulder l of such nose above thc abut' ment or part, fin, and thereby enable the bar E to be drawn out of connection with the draw-bar.

1 am aware of the invention described in the United States' patent, No. 5,961, dated December 12, 1848, and granted to Daniel R. Pratt, for a car-coupling, and make no claim thereto.

With my invention it will be seen that I do not employ an open link for connecting the two. carriages, and that my coupling-bar E catches or hooks upon a part,

"In, of the draw-bar, in order for the connection of such two bars. Also, that while the cars are coupled, it is so held in connection by the lever D.

'I therefore claim the arrangement and combination ofthe arms b c, and part or abutment, fm, with the lever D, the draw-bar chamber B, and its mouth O, substantially as described, the whole being`to operate in manner and for the purpose specied, with a connectionbar,- E, made as set forth.
