J. PINNEY. LINK LIFTER.

No. 478,932. Patented July 12, 1892.

LINK-LIFTER.

SPECIFICATION forming part of Letters Patent No. 478,932, dated July 12, 1892.

Application filed November 6 1891. Serial No. 11,094. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN FINNEY, a citizen of the United States of America, residing at Portland, Multnomah county, Oregon, have invented certain new and useful Improvements in Oar-Couplers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to that class of carcouplings which is provided with devices for raising the link; and the invention consists in the peculiar construction, arrangement, and combinations of parts hereinafter more particularly described, and then definitely claimed.

In the accompanying drawings, Figure 1 is a side View of a coupling provided with my improvement. Fig. 2 is areversed plan of the same.

Referringnow to the details of the drawings by letter, A represents an ordinary car-coupling, in which is mounted a rock-shaft B,car-

rying on its opposite ends the arms 0, one of which is connected to a cog-wheel D. The free ends of the arm 0 are connected by a cross-bar E, which is so arranged as to raise the coupling-link F when desired.

At G is shown a lever havingatoothed segment 9 on its pivoted end, which segment gears with the cog-Wheel D.

Under the bed of the car is pivoted a lever H, having handle h, and which is connected with the lever G by a chain I.

The operation is as follows: WVhen it is desired to couple two cars together, the operator takes hold of the handle h and by moving the outer end of the lever toward the coupling pulls on the chain I, and thus operates the lever G, causing the segmentgto act on the cogwheel D, and thus lift the arms 0, which will cause the cross-bar E to act on and raise the link F to the desired elevation to enter the mouth of the opposite draw-bar. By this means cars can be coupled without any danger to the operator, thus saving many lives now lost by going between cars to couple them.

If a duplicate of the lever H is attached on the opposite side of the car, the coupling can be done with equal facility on either side, although for all practical purposes a single lever H is sufficient.

What I claim as new is- The combination, with a draw-bar, of the arms 0, carrying cross-bar E, a cog-wheel D, connected to the arms, a lever G, having toothed segment g meshing with the wheel D, a lever H, and a chain I, connecting the levers G and H, all substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses, this 28th day of October, 1891.

JOHN FINNEY.
