CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 317,178, dated May 5, 1885.

v Application filed December 20, 1884. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. NIEHAUs, of the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Car-Oouplings, of which thei'ollowingis a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specication.

Figure lis a horizontal section at l l, Fig. 2. Fig. 2 is a vertical longitudinal section at 2 2, Fig. 1. Fig. 3 is a front endview of a drawhead. Fig. 4 is a transverse section at 4 4, Fig. 6. Fig. 5 is a transverse section at 5 5, Fig. 6. Fig. 6 is a side view.

A is part of the draw-head body, secured to the car in any usual or suitable manner.

B is the recess to receive the end of the link O, which link may be of ordinary construction. It must, however, have sufficient length to allow the working of the latch D upon its pin E when that end of thelink is in its inner position, as shown at m, Fig. 2.

The top andy bottom of the draw-head are slotted longitudinally at F and G, the latch working in these slots. Y

H is an elevation extending above the floor of the cavity or recess B, said elevation being inclined on the front and rear side, so that the end of the link will freely slide over the elevation in entering and leaving the draw-head and surround the elevation. The slot G may extend to the apex of this elevation, ,as shown, so as to avoid any tendency in the link to bend the latch, as the elevation may extend above the level of the point of bearing of the link upon the latch, so that the strain of the link upon the latch may be in direct line with the elevation. By the use of this elevation `the latch may be shortened, so as to lessen the distance it is necessary the link should enter the draw-head to allow the latch to swing within it.

D is a horn on the rear side of the latch D, which holds down the inner end of the link,

l and thus sustains the link in a horizontal position, so that itwill enter the draw-head of another car. This horn may have a knob, D2, to checkthe inward movement of the link when entering the draw-head of another ear.

I are ribs in the upper corners of the recess B, which prevent the inner endof the link flying upward when the cars are coupled and mounting the back of the horn D. tive construction of the elevation H and ribs is such that the end of the link may pass between them with sufcient ease in entering or leaving the recess B.

D3 is a handle upon the latch, by which the latch may be thrown up into the position shown in Figs. l and 3 and in Fig.` 2 at to allow link to be drawn out when uncoupling the cars. The coupling of the cars is automatic, the end of the link forcing the latch upward and backward in entering the recess B.

portions, slot G, and ribs I I.

In a car-coupling, the combination of a draw-head, A, formed with a recess or mouth, B, elevation or tongue H, extending above inclined front and rear portions, slot G, eX- tending up through the rear portion of the elevation or tongue, ribs I I, and latch-slot F, and the latch D, having horn D', formed with knob D2, and a handle, D3.
