IMPROVEMENT IN CAR-columnas.

The Schedule referred to in thee-e LettersvPatent and making pan of the same.

To all lwhom it may concern Be it known that I, WILLIAM WIMER, of Union City, inthe county of Randolph, State of Indiana, have inventedcertain new and useful Improvements in Car- Gouplings; and I do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings making part of this speeicaionfin which- Figure 1 is aside view ot' the coupling and section of car.

Figure 2 is a top view of fig. l.

Figure 3, a detached section.

Like lettels of 'rete-rence refer to4 like parts in the different views.

This invention relates to a railroad car-coupling, the nature of which is such that it is self-coupling,

,thereby avoiding the necessity of' goin'g between the cars for that purpose.

A more full and complete description of the same is as follows, viz:

In fig. 1, A represents aseotion .of a car tn which the coupling is attached. Said coupling is constructed in two sections, B C, each section being attached to the under side of a car by any appropriate device.

Said section consists of two plates of iron connected -to each other by studs or bolts D, and which forms the head or buffer of the coupling.

Between the plates of one section are arranged pair ofhooks, F F, tig. 3.

Hook F is pivted in the plates by the stud D, iig.

1,-whereas the hook E is pivoted therein by the shaft G, towhieh it is attached and operated as will hereafter be shown.

The two'- hooks are connected to each other bythe link H, and are operated conjointly for coupling and uncoupling the cars.

I is a spring, whereby. the hooks are closed upon each other in the act of coupling.

Having. thus described the construction andan-angement ofthe coupling, the practical operation of the same is as follows, viz:

It will be observed that the two hooks project from the buffer-head in a horizontal direction, which, as the cars approach the stud I) of section C, impingeupon thc outer curves of the hook, and forces them laterally apart and allows the stud to pass in the back of the barbs; the hooks are then sprung together by the spring I, thus inclosing the stud and completing the. act ofcoupliug The cars are uncoupled by opening the hooks, thereby liberating the stud, and which may be kept thus open bythe dog J being made to engage in a notch, a, out in the collar k on the shaft G, whereby the hooks wereopened for the liberation of the studs.

The shaft G is operated for opening the hooks by means ofthe hand-wheel L, thereby avoiding the danger of going between the cars for the purpose oifun- `coupling them. The shaft may also be operated by? the rod M,to which it is connected byan-arm, N, actuating as a lever, so that the cars can be uncoupled without mounting to the top to obtain access to the hand-wheel above referred to.

The cars when thus connected cannot become disconnected in consequence of any sidestrain exerted upon the coupling, though the strain be sufficient to `open the hooks; thestud cannot slip therefrom, but will be securely retained by one or other of the hooks,

as the direction of the draft maybe.

Should the hook not be required for coupling, they may be dispensed with, anda link, fig. 4, be used in place thereof, by inserting the pins D in the holes c, and in this way converting the coupling immediately into that of the link and pin in ordinary use.

What I claim as my improvement, and desire to secure' by Letters Patent, is

The hooks E F, link H, spring Land studs D, in combination withthe shaft G, arm N, and rod M, substantially as and for the purpose set forth.
