GEORGE WORDEN, OF PITTSTON, PENNSYLVANIA.

IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent N0. 150.454, dated May 5, 1874; applica-tion tiled January 14, 1874.

To all whom it may concern:

Be it known that I, GEORGE WORDEN, of Pittston, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Couplingsy and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, r eference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in car-couplings, and is designed as an improve ment upon patents granted to me January 2, 1872, No. 122,509, and December 31, 1872, N o. 134,503.

In the drawings, Figure 1 represents a longitudinal section of my invention, and Fig. 2 a plan View of the same.

My invention consists in the following parts in combination, whereing A AJL are draw heads of opposing cars. These draw-headsA are constructed substantially in the manner as shown in my previous inventions referred to. Upon the draw-head A are arranged suitable supports and bearings for levers and other mechanism, as will here inafter appear. B is a primary lever, against which ixnpinges the coupling-link F. This lever B moves in a slot made in the upper portion Of the draw-head, and swings upon a pivot, b. O is the` secondary lever, fulcrumed at b, and operated by the primary lever B. D is a pin-lever, operated by the secondary lever O. The pin-lever D swings in a suitable casing placed upon the draw-head A, in which it is fulcrumed at D', and operated by the secondary lever O. At the extremity of the pinlever D is provided a slot, g, in which is hung the coupling-pin E. The construction of the draw-head A, with its weighted slide A2, is substantially the same as shown and claimed in my patent of .December 31, 1872,' before mentioned. Y

The link F is held in proper position in the drawhead A1 by the action of the weighted slide A2, which enables said coupling-link to properly enter the flaring mouth of the drawhead A., As the link F enters said draw-head A it impinges against theprimary lever B,

which, in its action, lifts the secondary lever 0, which, in its turn, elevates the pin-lever D by its gravity and that of its lever D, drops into position, and the cars are automatically coupled. To uncouple, it is only necessary to elevate pinlever D, which may be done directly, or by any suitable mechanical device. This disengages Athe coupling-pin E, and the link F may be drawn out, the primary lever B ,being so constructed as to swing free from said llink.

It will be seen that, in this invention, I have improved on the devices in my previous patents referred to in the following points, viz: A decrease in the number of parts, and consequent decrease in friction; a decrease in cost of construction; greater simplicity; more direct action, and less liability to derangement. I have also placed my primary lever B in the roof of the draw-head A, instead of the door, as shown in my previous patents. By this, the coupling-link is less liable to be obstructed in its entrance by the coupling-pin E.

By this system of levers it will be observedthat a much shorter draw-head can be used, whereas, when a single lever is, used, it neces sarily requires a long lever-arm, and also a correspondingly long drawhead in which to operate said lever and its pin. It is obvious that, by my invention, a short draw-head may be employed, thus aifording the advantages of economy of room, cheapness of construction, and greater strength.

What I claim is- The combination of the draw-head A, primary lever B, secondary lever O, pinlever D, and pin E, substantially as and for the purposes specified.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of January, 187 4.

GEORGE WORDEN.
