TRAVELING HOIST.

Speccaton of Letters Patent.

Patented Oct. 4, 1921.

Application filed Uctober 1Q, 1919. Serial No. 329,595.

To o-ZZ whom 'it may concern.'

Be it known that I, RICHARD L. Neuen-RT, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Traveling Hoists, of which the following is a specification, reference being had to the ac ompanying drawing.

My improvement relates particularly to hoisting and carrying mechanism wherein a cable or wire rope or similar member forms an elevated track on which is supported a depending carriage which is made to travel on said track by means of ropes or cables leading to a station at or in the direction of one end of said track and being there connected with drums or windlasses, a cable or rope depending from the carriage and serving as a` load-line or picking-up line which is raised and lowered to handle the loads which the apparatus is to transport.

One object of the invention is to provide such an apparatus adapted to raise and transport heavy loads over a relatively extended range, both longitudinal and lateral. For example, the apparatus is intended to collect saw-logs scattered over an extended surface and deliver them on railway cars or elsewhere. For this service, an extremely strong equipment is required; but strength must be attained with the least possible weight of the traveling part of the equipment, for said part of the equipment is usually supported by a long cable supported only at its ends. On account of the lateral range necessary and the lateral oscillation during` carrying, special features must be embodied in the traveling part of the equipment. lt is a further object of my invention to provide such features. A further object of the invention is to so control ropes or cables as to prevent their twisting and over-lapping and consequent kinking and entangling.

In the accompanying drawings,

Fig. lO is a section between the two middle disks of said pulley;

Fig. ll is an elevation, partially in section, of one of the grooved rollers for staying the edges ot the disks oi" the multiple pulley;

Fig. l2 is an end view, partially in section,

of the same rollers. Referring to said drawings, A is the elevated track upon which the carriage, B, travels. Said track is ordinarily a wire cable of ample strength and of suliicient length to permit operating over a considerable area. For logging this cable is sometimes as much as twenty-five hundred feet long. The ends ot-this cable are attached to firm supports at suitable elevations above the ground, as is well known. The body ormain part of the carriage comprises two grooved wheels", B1, each having an axle, B2, which is horizontal and transverse to the course of the cable. Ear-h end ot each of said axles rests in a bearing, B3, formed in the adjacent upper end of a U-shape trame member, B4. A horizontal frame member B5, extends across each U-shape member and has its ends secured to the ends of the U-sliape member a little below the wheels, B1.

In the lower part of each of the U-shape members is a bearing, B6. An axle, B7, extends horizontally through said two bearings and forms' a support for a multiple pulley, C. Said pulley comprises a. bushing. C1, .spacing rings, C2, surrounding the bushing, four sheet metal disks, C3, separated from each other by said spacing rings.

ond and the third and fourth disks and each.

of said rings is secured to the adjacent disks by means ot bOlts or rivets, C7. The thickness of the spacing rings, CA1 and C, is proximately equal to the thickness ot the cables to be applied to said pulley, in order that the coils ot each cable must rest upon each other and not side by side. This prevents entangling' and wedging and consequent cutting. Six stayingv rollers, D, each having` four circumferential grooves, D1, are applied to the peripheries ot the disks, C3, to stay the disks against lateral bendine, each ot the grooves ot said rollers receiving the edge of one of said disks. Two ot said rollers are supported on axles, D2, extending horizontally through the horizontal framev members, B5. Another two et said rollers are supported on horizontal axles, D2, extending through the U-shape members, Bt. Another of said rollers is supported onv an axle, D2, which rests in a U- shape yoke, D, which has its arms extending across the pulley, C, and overlapping` and secured to the U-shape members, B4, b v bolts or rivets or otherwise. The sixth of said rollers is support-ed on a horizontal axle, D2, which is supported in two extension plates, D4, said plates are upright and located opposite each other and overlap the adjacent parts of the U-shape' members and are suitably secured to said members, as by means ot bolts or rivets. Between the plates, D4, are two grooved guide pulleys,

.D", each having an axle, D, resting in said plates.

VAt the right of the U-shape member, B4,

is the articulated extension, E, ot the carriage. Said extension comprises two grooved rollers, El, resting on the track cable, A, and having' axles, E2, and a guide pulley, E3, having an axle, Et, and parallel upright plates, E5, located at opposite sides ot the cable, A, and supportingthe axles. E2 and E4. A horizontal'tork or clevis, E,

lhas its arms extending across and secured to the outer. upright, side taces'ot the frame members, B5. The fork extends horizontally toward the carriage extension, E, and has in its right hand portion a horizontal bearing, El, through which extends a horizontal tube, ES, which is smaller than the bearing. At each side ot the bearing, E@

made concave and the adjacent faces of the nuts being; made convex. Thus the tube 1s left free to turn on its axis and laterally in the'bearing, E7. Thus a universal joint is formed between said tube and the main frame of the carriage. The right hand end of said tube is split along an upright plane, and the two arms, El, thus formed are made to overlap the outer side faces of the plates, E, and said arms are secured to said plates by riveting or otherwise. A

forked brace, E11, has one'end secured to the tube, ES, while itsv other end is secured to the lower ends of the plates, E5. The function of this brace is to Ygive rigidity to the extension ot' the carriage.

t A grooved roller. E12, having an axle, E13,

is seated between the U-shape members, B4, at the right of the tube, ES, the axle, E13, being seated in the U-shape members at the proper elevation to bring the upper part lof said pulley to the level ot' the bore of said tube.

The ropes or cables whereby the carriage is made to travel on the track, A', and whereby the load to be hoisted and transported is r -Ved or lowered will now be described.

A rope or cable, F, is attached to the lett hand part otl the carriage frame and extends thence horizontally to a drum, F1. A rope, (l, is attached to the right hand end oli' the carriage extension,-E, and goes thence over guide pulleys. G1, to a drum, G2. By drawing the rope. F, and releasing the rope, G, the entire carriage drawn toward the lett. By releasing the rope, E, and winding the rope, G, on the drum, G2. the entire carria ,qe is drawn toward the right on the track, The rope, H, which is to carry a load, L, extends upwardto and acrossjthe guide pulley. E3, and thence horizontally and'lett-V ward between the plates, Eiyandthrough the tube, ES. and-over tne guide pulley, E12.

IOO

guide pulley, D, and to the drum, Il, to Y which said rope is attached. A rope, J, extends between the other outer twofof said disks and to the ring', C6, which separates said disks. There said rope is suitably secured; and said rope extends thence lettward'over the lower ot the two guide pulleys, D5, and to the drum, Jhrto which the rope is attached. Y In assembling the apparatas, either the rope, I, or the rope, J, is wound on the pulley, C, while the other rope is not wound or is wound in the opposite direction. Turning-the drum. I1, for drawing the rope., I, (if that rope is wound on the pulley. C, and the rope, H, is at the time unwound) will cause Vthe rotation of the pulley, C,- in the proper direction toV wind the rope, H. on said pulley, whereby the load, L, will be lifted. To lower the free end of the rope, H, to receive or discharge a* load, the drum, I1, is to be released and the drum, J1, rotatcd.`

One form 'for securing the cables, I and'J, and the load-line, this shown in Figs'. 8, 9 and 10. l,The spacing rings,- C? and C5, are

each provided with a gap, C8, through which the cable which is applied to said ring is passed. Between said rings and the axle, B7, portions of the disks are cut out to leave spokes, C9. Through the openings thus yformed, the cables can be reached and brought around the axle and secured by clamps, C10.

It is to be observed that the drums, F1, I1, J1, and G2, may be closely grouped for convenient control, as is well known in this art.

The tube, E3, and the guide rollers, E3, and E12, are brought as close as feasible to the track cable, A., in order Vthat lateral swaying of the load on the rope, H, or lateral range of the rope to take a load may take place with ease and with least strain upon the extension, E, of the carriage. ln other words, the aim is to give the depending part of the rope, H, and the carriage extension, E, freedom for pendulum movement on the cable independently ot late-ral swaying of the main part of the carriage, so that that pendulum movement can take place without compelling corresponding lateral movement of the. main part of the frame, and also so that any lateral strain placed upon the main part of the trame through the ropes, F, G, l, and J, or otherwise, will not be transmitted to the carriage extension E. Furthermore, the universal joint whereby the two sections of the carriage are articulated allows the two sections to adapt themselves to varying curvature of the track cable. Y

lt is to be observed that the various features of my improved carriage are suited to the attainment of strength with lightness. Attention is specially invited to the combination oi' the disks, C3, and the rings, C4 and C, and the grooved rollers, D, whereby the edges of said disks are stayed. These features make for lightness. InY the absence of the grooved rollers, D, the disks and other parts of the pulley, C, would have to be much heavier. rlhe forming of the universal joint between the main part of the carriage and the carriage extension also makes for lightness. 'lf the two sections of the carriage were not thus articulated, the carriage would have to be made much heavier in order to fit it to resist the strains which would be put upon it.

Attention is also directed to the fact that each of the cables, F, G, I, and J, has both ends secured to parts which allow no twisting and consequent kinking of the cables when they are slack. Thus a serious defect in similar apparatus now in use is avoided.
