CABLE -LIFTING MECHANISM.

aracrrrcatrxorr forming part of Letters Patent No. 347,785, dated August 24, lacs? Application filed February 1'2, 1586. Serial No. 191,683. (No model.)

To all whom, it may concern:

Be it known that I, JOHN J. Farmers, of the city, county, and State of New York, have invented'certain uewand useful Improvements in Cable-Lifting Mechanism for Cable-Road Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to mechanism for cable-road cars, by which the cable may be grasped and lifted from its normal position on its carrying-pulleys and brought between the jaws of the cablegri p on the car by the operation of a suitably-arranged hand-operating mechanism.

The mechanism embodying the invention will be explained by the following description, and the features considered as new will be specially indicated in the claims.

In the drawings, Figure 1 is a side elevation view of a car-trnck, the wheels on one side being removed, and provided with my improved cable-lifting mechanism mounted thereon. Fig. 2 is a plan View of the same. Fig. 3 is a cross-section on plane 00 0c of Fig.2, and Fig. 4 is a detail side view of the cableclutching-jaws.

Referring to these views in detail, A represents the frame of the truck, which frame may be of any suitable construction, it being preferably a frame rigidly connecting the axles B B of the truck and adapted to carrying thereon a cable-gripping mechanism. Such gripping mechanism is designed to be attached midway between the axles to the cross-bars D. At each end of the truck is a cross-bar, E, constructed with a vertical guide-bearing, F, through which passes the cylindrical plunger G, to the lower end of which are hinged the cable-jaws H, which are provided with friction-plates I-shaped and secured to said arms, so as to jointly form a grasp about the size of or a little larger than the cable J. This hollow plunger is pivotally suspended by connecting-rods K from the weighted levers L,looselyhung on the crank-shaft M, jonrnaled on the frame of the truck. Through these levers M the plunger is counterbalanced by the movable weights U, or by springs or any like means, and is thus held up so that the jaws H are sufficiently above the normal position of the cable to clear -it and its carryingpulleys.

Pivoted to each of the j aws H is a toggle-link, O, and these links are at their other ends pivoted to the lower end of the crank-rod P, which is pivoted at its upper end to the arm Q, this arm being rigidly attached to the crank-shaft M, and the cranks R of the shafts at each end of the truck being connected so as to operate together by the rod S, which is attached to any suitable hand-operating mechanismsuch as a handwheel or hand-lever and usually located on the car-body within convenient reach of the conductor of the car.

T indicates (in dotted lines in Fig. 1) the grip, by which the cable is attached to the truck of the car. This grip may be of any form, the form shown, however, indicating a fixed upper jaw, U, and a movable lower jaw, V, while W indicates levers at each end of the grip for raising and lowering the movable jaw, the grip being of the kind that takes the cable sidewise.

The operation of the mechanism is as follows, the position of the parts being as shown in Fig. 3, but with the jaws open, and the position of the cable when running on its carrying pulleys being as indicated in broken lines. The conductor through his hand-lever or hand- Wheel pulls the rod connecting the crankshafts and forces down the crank-rods attached to the toggle-arms until the links 0 strike the stops H. XVhen the cable-jaws are extended, these crank-rods can be pushed no farther through the cylindrical plungers, and the further revolution of the crank-shafts causes theplungers to be pushed down through their bearings, so as to bring the cable-jaws on either side of the cable, as seen in dotted lines in Fig. 3. This downward movement of the hollow plungers lifts their weights so that in this position of the parts they do not counterbalance the plungers, and the plungers will remain as placed when the conductors handoperating mechanism is reversed. Upon reversing such hand mechanism the backward revolution of the crank-shafts causes the cable-jaws to first close together under the cable and then to lift the plungers, with the engaged cable, to a line with the open jaws of the cablegripping mechanism, as seen in full lines in Fig. 3. Ihe gripping mechanism may now -be closed, and then the hand mechanism of the cable-lifting devices can be released, when 1o ping devices the cable is held evenly between the gripping-jaws. In some cases, however, a single lifting mechanism might sufficeybut generally it is better to have the cable lifted at two points, so that that portion of the cable 15 passing through the grip may be along a straight line parallel with the clamping-faces of the grip.

In an application for a patent filed by me of same date as this application, and numbered 20 189,600, I show a form of grip particularly adapted for use in connection with the cablelifting devices here shown; but various other forms of grips are equally suitable.

The parts of these mechanisms may be 2 5 changed as to shape and construction without essentially altering their purpose and operation; and I do not, therefore, confine myself to the exact construction here shown.

I" hat I claim as new is- 1. In combination, in the herein-described cable-lifting mechanism, the jaws H, pivoted to the counterbalanced plunger, and the crank-rod P, attached to said jaws and to connections extending to handoperating mechanism, substantially as and for the purpose set forth.

2. In combination, the jaws H, the counter balanced plunger G, carrying the same, the crank-rod I for operating said jaws and attached to the crank-shaft M, and the connecting-rod S, all substantially as set forth. 7 3. In combination,theplungerG ,suspcndcd from the weighted levers L and carrying the jaws H, the links 0, and crank-rod P, the crank-shaft M, and connecting-rod S.

4. In combination, the two cable-lifting mechanisms arranged to engage the cable at points on both sides of the gripping mechanism, each consisting of a verticallymoving counterbalanced plunger carrying cable-lift ingj aws, and a crank-rod connection arranged to move said plunger and operate said jaws, substantially as anll for the purpose set forth.
