CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 326,882, dated September 22, 1885.

Application filed July 13, 1885. (No model.)

To all whom it may concern:

Be it known that I, OLIVER J. MrcHAnLs, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Oar-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 IO thesame,referencebeinghadtotheaccompanying drawings, which form a part ot' this speciiication.

This invention relates to an improved form of car-coupling; and it consists inthe peculiar construction and combination of the drawhead and coupling-pin, substantially as hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a longitudinal vertical section of the drawhead, and Fig. 2 is a perspective View ot' my improved form of coupling-pin. Figs.. 3, 4, and 5 are longitudinal sections of paired drawheads in diii'erent relations, Fig. 3 showing the coupled position while in use, Fig. 4

5 showing the coupling-pin on the right as set for self-coupling with the link striking it, and Fig. 5 shows the saine pin drawn back about to be tilted by drawing upwardly the chain. Fig. 6 is a view of one end of a car provided with my draw-head and coupling devices.

More particularly my invention is as follows:

The coupling-pin A is an L-shaped device forming,su lostantially,a right-angle,and at the angle projects laterally on each sidethe pivots 5 or trunnions b,the angle back of these (marked c) being rounded off to substantially describe a circular face on the axis of said pivots.

rIhe draw-head D is of the usual massive form in front,with its faces converging to the 40 link-opening c, from which a horizontal slot or groove, j', extends backwardl y into the draw-head, forming a cavity ot' suiiicient length and width to accommodate the link g in all its movements for coupling and uncoupling and during the oscillation ot' the car in motion. A vertical slot, It, is formed lengthwise of the draw-head along its center,and of a width just enough greater than the thickness of the pin A to allow the latter to move freely.

5o Slot h has greater vertical depth than thelinkslot or groove f, and is also longer, but only begins at the rear of the enlarged front of draw-head D, where it is formed square to make the abutments t' t' which receive the strain of the pin A when in use. In thelower part of the walls of slot h, I form the horizontal pivot-slots 7c, opening near the front upwardly into the link-slotf,as shown in Fig. l. The link A is slipped in through the front and its pivots b lowered till they rest in the 6o pivot-slots k, wherein they can slide freely forwardly or backwardly. I prefer to make the rear member of the pin A somewhat heavier than the other portion. By reason of the position of the pivots b, the link A always gravitates toward the front or rear,as shown in the figures. I attach a chain, m, to its rear end, which is carried thence up to or near the roof of the car,and by a branch overa pulley, N,laterally along the front of the platform or cartiinbers to a suitable lever, P.

Referring to Fig. 4, the facility for automatic coupling will be readily understood. In the draw-head, at the right of the ligure, the pin A is drawn back and turned over so as to have its front member horizontal,which is the only preparation required. The linkg of the other drawhead,when the cars come together, strikes the now uppermost rear portion of pin A, which, immediately turning on its pivots, so tilts over backwardly, and its front partenters the link and assumes a vertical position. The opposite movement of thelink then,since the pivots b are free to move in that direction, simply carries the pin A bodily forward till it strikes the abutments or shoulders z"i,and the coupling is effected.

To uncouple, the cars are moved together slightly, after which the chain m is used to withdraw the pin A backwardly till it takes 9o the position shown by Fig. 5, when a further pull on the chain tilts the pin, into the position shown by Fig. 4, whereupon the link is free and the car uncoupled.

The cars can thus be coupled and uncoupled with perfect ease without any necessity for the brakeman to risk his life between the cars, all the required manipulations being accomplished with great facility by the use of the chain only.

To accommodate a common coupling-pin, I form the cavity sin the under wall of the draw- IOO head, which forms a socket to sustain the pin in the ordinary position.

I claim as my invention- 1. In a ear-coupling, the draw-head D,hav ing link-opening e and groove f, vertical pinsIot h, and abutments i t', in combination With the right-angle pin A, located in said slot h and adapted to stand with either its front `or rear portion vertical, and having lateral pivots b at its angle, substantially as described.

2. In aear-coup1ing,the draw-head D, having link-opening e, groove f, vertical pin-slot h, abutments z' i, and horizontal pivot-slots lq, in combination With the right-angled pin A, having lateral pivots b, substantially as described.

'my own I have hereto affixed my signature in presence of two witnesses.

OLIVER J. MICHAELS.
