To ulZ who-m it may concern:

Be it known that we, TnoMas Srnxcun MILLER, a citizen ofthe United States, and a resident of South Orange, in the county of Essen; and State of New Jersey, and Josneu H. Dlcsixsmv, a citizen of the United States, and a resident of Atlanta, in the county of Fulton and State of Georgia, have invented a new'and Improved Hoisting and Convey- '10 ing Den'ce, of which the following is a full,

clcar, and exact description.

Our invention relates to improvements in hoisting and conveying devices, and in the drawings accompanying herewith is shown as embodied in a eableway for collecting logs.

Our invention comprisesnovel parts and combinations of parts which will be hereinafter described and particularly set forth in the claims.

Figures 1 and 2 are elevations of cablewa rs employing our inventionin two slightly different forms. Fig. 3 is a side elevation,

. Fig. 4 an end elevation and Fig. 5 a horizontal'section of the carriage, shown in Fig. 1. Fig. (i is a plan of the operating parts of the carriage shown in Fig. 1. Fig. 7 is a plan of the operating parts of the carriage as shown in Fig. 2. Fig. 8 is a detail partly in section,

showing a construction suitable for the friction hoisting-drum and the friction slackpulling-l l m m hoisting and conveying devices which employ a traveling load carriage, much dilli cully is experienced in causing the fall when unload d to prom My take up the slack in the loweriug'or fail rope. The weight of'the securing tackle on the end of the fall th- 40 gether with the weight of the rope end and sometimes an additional weight secured thereto, is usually relied upon to pull out the slack amount in our present invention we have provided a slack puller or means for paying out the hoist rope so that a prompt and rapid'paying out of this rope ma he socured.

In' both Figs. 1 and .2, Sand 5' represent, respectively, head and tail supports for a cableway, A thctraeliway cable, ll the h'oist or fall rope, and 'l the traction or carriage hauling rope. The head and tail support-s are provided with suit-able guides for the various ropes. Three friction rope drums D, D and D are shown driven by a suitable engine; 1) having the. traction rope connected therewith; D and D having the rope or ropes connected therewith by which the raising and lowering of the load and the fall rope is secured. Each of these friction ropedrums may be of the construction shown in Fig. Swherein the driven spur-wheel 1 fast upon the shaft 2 carries a V-shaped friction ring 3 entering a corresponding recess in the flange 4 of the rope-drum 5 which is loose upon the shaft 2 and is pressed toward the spur wheel 1 in opposition to the coil spring 6 by the cross key 7.

A band-brake S is applied to the exterior of the flange 4. \Vhen neither the handbrake nor the'friction ring engages the ro a: drum it pays out its rope freely. When t re band-brake is disengaged but the friction ring is engaged, it hauls in its rope. When the friction ring is disengaged and the hand brake is engaged, it holds its rope stationary. When the brake is lightly engaged, the paying out of the rope is under tension. When the friction ring is so lightly engaged as to friction I'(lp(.(l[UiHS D, D andl), the oper- 'ln the operation of cable-waysand other ator althe engine is enabled to operate and control the tluee ropes B, and T in the manner hereinafter described without. ermitling any substantiallyundesirable s ack in any of said ropes.

Upon the trackway cable is atrolley- F from which is suspended. a load carriage E comaining the drum I, which receives the hoist or fall rope H. and the drum or drums loo are fixedlyor consisth .20 The dri Q a 878,482 g integrally connected to ether, and to respectively, are secure the ends of the runs of rope. B and C by which the hoist rope is operated: The drum-part G, which re-' mixes the slack pulling run of rope C, 15 preferably slightly larger than the drum part G which receives the hoist-operating run of IO e B, thus' necessitating less power to over aul therope B than would be required .10 were both drums of substantially the same 7 diameter, thus enabling us to employ a relativel light'siack pulling rope C. V e have shown the fall H as containing only a single run of rope and the drum 1 as of only one part or barrel but we do not wish to limit ourselves in this regard, since it is evident that the runs of fall-rope ma be manifolded to multipldy the power oft e hoist to any extent desire connection between the drums G and I is town as the intermeshing gear wheels J and J so that when one drum turns the other must also, but We do not wish to limitourselves to this form of driving con- .25 nection. The traction rope T, as shown in Fig. 1, is substantially an endless rope coupled to the carriage E;

. Instead of the construction above described, that indicated in Fig. 7 may be so employed. In this form the two drums G G are merged into one drum (3! which 'receives the loop of the single rope composed of the two runs B, C, which communicates its motion to the drum b its frictional grip 55 thereon. The fallrope' rum I is a storage drum of sufiicient capacity to accommodate the maximum length of fall rope which will I be needed. The drum G2 preferably contains an elliptical groove with sufficient 40 wraps of the rope therein to give the rope a sufficient grip on the wheel; though other gri ping means maybe substituted.

t is evident that by opgerating the hoist operating the runs of rope C, or B, C, the

fall rope may be raised or lowered at will and 6,5 We are aware that the Dusedau Patent.

the speed of lowerin is independent of the weight ofthat part 0 the rope then out, or of I the attaclunentis thereto. It will therefore be possible to lower it at a greater rate of SO-uspeed than when! its weight alone relied u on. The use of fall rope carriers may be .a o obviated with all the troubles attendant thereupon.

In moving the carriage along the trackway the hoist operating rope or ropes must he wound in or mid out to correspond with the I u movement oi the carriage if there is to he no hoisting or lowering of the'load. Two drums D and I) are therefore required to operate 80 this rope. The frame E is supplied with different points of attachment ortho sus pendinglink f, as by the holes a so that the suspension point may be shiftgd as necessary to make the ropes pull right. i

No 566,849, dac zfie tembei' 1, 1896, describes two operative y connected drums mounted on the load-carriage and containing a-fall-rope, a run of hoisting ropeand a run of slack-pulling rope, said runs of hoisting re esfand slack-pulling rope constituting di erent parts of the same-endless rope and extending from the load-carriage drum, respectively, in op osite directions to o posite ends of the tree ray and'operated by the same drum at the engine. In our construction, on the-contrary, the tail ends of our slack-pulling ro C or C and hoisting-rope B or are hot 1 at the'carriage where said tail ends are connected together and with the of the ropes to drums eared together as are the drums B and I oi Figs. '6 and 7. Our hoisting and slack-pulling rope runs are in versely wound on the drum or 'drum parts and preferably leave the drum-or drum parts at points respectively below and above the same. In our construction two distinct friction-rope-drurns D" and D are employed for operating the slack-pulling and hoisting 160 ropes, respectivelygso t at bv inhauling on both of said drums in unison t 1e drum mechanism on the load-carriage may be held sta-v tionary as the carriage moves toward the head-support and vice versa, by payin out on the drums D, D in unison, the m mechanism on the load-carriage may he held stationary as the load-carriage travels toward the tailsupport. But when it is desired to operate the drum mechanism on the load-carriage in either direction, it may be done by hauling in on one of the drums D or D while the slipping of the friction of the other drum permits it to pay out under suffic1ent tension to maintain any required tautness of said hoisting and slack-pulling ropes. 1

Although we meter that the rope-drum mechanism.should consist of three distinct rope-drums operativcly connected together, as shown in Fig. (i, and the three ropes B, C and ll should be distinct and separateropes each connected with one of said rope-drums, nevertheless either two of said ropwdrums may be mergml together and either two of said ropes may he nwrgud together; as, for

example, in Fig. 7, where the rope-drums (l, i, of Fig. (i. are nu'lgmi into the rope-drum or sheave (F, and the ropes li and l of Fig. (3 are merged into the continuous I'Qlll' B, U, 1:30

making the combination of the drum G with the ropes B, C the substantial equivalent of the drums G, G and ropes B, C.

. way, we do not limit ourselves thereto since certain of the principles of our invention mightbe embodied in apparatus with the traveling drums mounted upon other forms of cdnveyance.
