CABLE-CARRIER.

SPECIFICATION forming part of Letters Patent No. 571,440, dated November 17, 1896 Application filed August 15, 1896. Serial No. 602,847. (No model.)

To all whom, it may concern.-

Be it known that we, EYVIND LEE IIEIDEN- motor usually derives its energy from an overhead feeder-wire, as in ordinary trolley systems. The motor serves to propel the car and thereby to transport the burden. The load is slung between suspenders which extend from the car and from a guide-trolley mounted on the cableway at a defined distance from the car. In common practice the suspenders take the form of the familiar block and fall, the fore and aft ropes running to a winch mechanism on the car actuated by the electric motor. Provision is made for propelling the car and for working the winch simultaneously, or again, if there be different winches for the separate falls, for working the winches in unison or independently, as may be requisite.

The invention is peculiarly fitted for transporting logs or like unwieldy burdens over a lateral cableway to the skid, chutes, landings,

or main-track line of the. system.

In the drawings like parts have like designation throughout.

Figure 1, Sheet 1, is a side elevation view of the car, the guide-trolley, and the tackle supportinga log. Fig. l is a rear view of the car. Fig. 2, Sheet II, is a plan view of the car, showing the motor, propulsion-sheaves, and the winch mechanism; Fig. 3, Sheet III, an interior side elevation, the car-body being in section.

The cableway a is supported in any suitgenerator at the skidway-station may conveniently serve as a source of supply for the current, which passes thence by feeder-wire Z2 and trolley-pole c to the motor cl, mounted on the car 6. The feeder-wire is strung along in familiar fashion in near relation to the cableway, while the pole and motor are of any usual approved pattern.

Upon the cableway a. travel the wheels f, having straps g at the axles thereof, and a distender h, affixed to the respective axles to determine the distance between the wheels. At one end the cross-braces i unite the carbody with the strap of the front wheel. At the opposite end a tie-rod k with turnbuckle Z thereon unites the rear wheel and car. By shifting the turnbuckle the tension on the drive-belts for the car may be varied. A guide-trolley m moves along the oableway in defined position to the car, the strap n of the trolleybein g flexibly united for such purpose to the rear end of distender h through the medium of connector 0, jointed thereto by bolt 19. The flexible relation of the trolley to the car-sustaining wheels enables the system to pass curves of short radius along the cableway without risk of jumping the track.

Upon a suitable frame Awithin the car is journaled the electric motor (Z in mesh by pinion q with the gear-wheel 'r of main shaft 3. Near its opposite end the shaft 3 loosely carries the companion sheaves 15, about which pass the d rivebelts u, extending thence overhead and front and rear to the sheaves 1) at the carrier-wheels f. Each of said Wheels f and its adjacent sheave t are rigidly united and revolve upon a common axle. By this provision whendrive-sheavest at the car are caused to revolve the overhead wheels fnecessarily partake of the movement, and thus the car is propelled.

gear-wheel 3, affixed to counter-shaft 4 of the The counter-shaft journals on the frame A and loosely sustains the winch-barrels 5, between which is a double The clutch enables either winch to be brought into action, as the operator may desire. Ratchet 7, affi Xed to one of the winches, encounters pawl 8 to prevent the barrel from unwinding. This expedient ordinarily comes into play after the winch has raised the load to suspended position and the car is being propelled to transport the burden. At such juncture the clutch 9 on main shaft 3 is thrown off from pinion 2, which latter being no longer positively driven rides loosely on shaft 3, and thus, except for pawl and ratchet 7 8, must that the main shaft through its clutches controls not only the propelling-Wheels, but also 1 the winch mechanism, and at times may compel their simultaneous action, as in effecting a flying lift of the burden.

Generally a single winch serves for raising and lowering the load. For this purpose the tackle consists of companion block and falls to suspend opposite ends of the log or other burden. Guide -block 10 and hookblock 11 with cable 12 are carried by trolley m, while car-block 13 and hook-block 14: with cable 15 are sustained from the car. The free ends of cables 12 15 move through block 14 and pass thence to the winch. Grippinghooks 16, carried from the straps of blocks 11 14:, seize the log and stoutly hold it in sus pended position.

The exterior or companion winch 011 counter-shaft 4 may be used at times for one of the lifting-cables, in which event the front an d rear falls for the bu rd en each has its own winder. Ordinarily the dual winch comes into play at other occasions, being used for snaking out logs from difficult or remote position preparatoryto transportation. The electric motor affords the requisite power immediately at command to aid the loggers in snaking their burdens to the traveling car.

Obviously the details can be varied according to the skill of the mechanic without essential departure from the principles of the invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination with the cableway and with the traveling car suspended therefrom, of the electric motor mounted on said car, the winch mechanism driven by said motor, the guide block separately sustained upon the cableway at a defined distance from the ear, the car-block and the dual tackles extended between each block and the winch mechanism therefor, substantially as described.

2. The combination with the cableway and with the traveling car suspended therefrom, of the electric motor mounted on said car, the companion winches driven by said motor, the guide-block sustained upon the cableway at defined distance from the car, the car-block and the separate tackles for each block and its corresponding winch, substantially as described.

3. The combination with the cableway and with the traveling car suspended therefrom,

of the electric motor mounted on said car, the

car-propelling wheels and the winch mechanism independently driven by said motor, the guide-block separately sustained upon the cableway, the carblock, and the separate tackles extended between each block and the winch mechanism therefor, substantially as described.
