IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 216,420, dated June 10, 1879; application filed April 16, 1879.

To all whom it may concern:

Be it known that I, SAMUEL HUDNALL Lass- WELL, of Weston, in the county of Platte and State of Missouri, have invented certain new and useful Improvements in Gar-Couplings; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a' front View of a box-car provided with my improved coupling. Fig. 2 is a side elevation of the front end of the same. Fig. 3 is a longitudinal section of the drawhead, and Fig. 4 is an enlarged perspective view of the mouth or opening of the draw-head.

Similar letters of reference indicate corresponding parts in all the figures.

This invention relates to automatic carcouplings; and consists in the detailed construction and combination of parts hereinafter described, and particularly pointed out in the claim.

In the drawings, A is the tubular draw-bar, which works against a buii'er-sprin g, a, .between two guides, b b, which prevent or control lateral play. The front end of the drawbar, constituting the draw-head B, projects up above the body of the bar, and is beveled off in front, as shown at c a, forming two parallel flanges united at the bottom by the lower part, 01, of the draw-head, and also united at the point where the rounded parts 0 c begin by a cross-bar, e. The upper part of the draw-head,

between the side flanges, c c, is open, for the insertion of the coupling-tongue O, which is pivoted upon a pin, f, bet-ween flanges c 0, just back of the cross-piece e.

The coupling-tongueGconsists offourpartsviz., an upward-projecting curved toe, g, a

sleeve, h, through which the pivot-pin or bolt f is inserted, a fiat web, 2', which impinges upon the cross-piece e, and the downward-projecting catch or tongue 75, the lower end of which impinges upon the raised or shouldered lower part, d, of the coupling-head.

Inside of the head B is arranged a spring, D, with its free front end projecting forward so as to bear against tongue k, when this is tilted upward and backward by the insertion of the link.

E is a bent lever, havin g its fulcrum in bear-.

ings Z Z in the front of the car, and operated from the roof of this by its handle E, which is inserted through a keeper, m, and may be kept in any given position by the catch or look spring 02.

The lower end of lever E forms a shoe, E, which works back of the toe gof the couplingtongue 0, so that when the lever-handle E is thrown back, throwing the shoe E forward, this will engage with the curved toe g, and, tilting it forward, tilt tongue it back, which admits of the withdrawal of the link in uncoupling the cars.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States In a car-coupling, the draw-head B, divided by the cross-bar 0 into an upper open and a lower closed chamber, and provided with a transverse pivot-bolt, f, set back of and above the cross-bar c, the pivoted tongue 0, having an upper curved toe, g, flat web 2', and catch or tongue 70, spring D, and bent lever E E E, all constructed and combined to operate as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

SAMUEL HUDNALL LASSWELL.
