Application filed December A28, 1901; Serial No. 87,564. (No model.) l

To a/ZZ whom t may concerm. Y

Be it known-'that-I, JAMES G. DELANEY, a citizen of the United States, and a resident of New York city, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Hoisting and Conveying Device, of which the following f is a full, clear, and exact description.

My invention relates to improvements in hoisting and conveying devices, and is herein illustrated as applied to a cableway, although it is evident that it may be employed as well in connection with any other form of tramway.

My invention comprises the novel features hereinafter described and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view` of a cableway constructed in accordance with my invention. Fig. 2 is a side elevation of engine-drums such as are requiredv for operating such a cableway. Fig. 3 is a sectional side elevation of the carriage, taken between the side plates or frames thereof, dotted lines H being added to indicate the position of the hoist-actuating rope. Figs. 4 and 5 are end and side elevations of a modified form ofcarriage. Fig. 6 is a top plan view of the block carrying the carriage-operating ropes at the tail end of the cableway.

A carriage C is provided with wheels l 2, adapted to runupon any suitable form of trackway, said trackway, as shown, consisting of the supporting-cableA. .A traction-rope B of the usual endless type is provided,by means of which the carriage may be caused to .travel along the trackway as desired. At theheadsupport or tower the runs of this rope pass, respectively, over the pulleys 3 and 4' and then p about a drum E of the engine, which is looselyT Y The carriage-frame is herein for simplicity shown as consisting of-two plates. Between these plates are journaled the wheels 1 and 2, which run upon the trackway and support the carriage, and the chain or hoisting pulley, sheave, or drum 8, which should preferably be a pocket or a sprocket wheel, which is adapted to engage the hoisting-chain I. When the hoisting member 8 is of the pocket or sprocket form shown it constitutes a clutching hoist member, which progressively clutches and releases the load-suspender I within each cycle of movement, andy therefore enables the point of suspension of the fall to be maintained in a laterally constant position with respect to the vertical plane through the supporting-cable A. Journaled upon the carriage is a wheel 7 which is adapted to receive asuiiicient number of wraps of a hoist-operating rope H so that power maybe conveyed by the frictional grip of the ropes thereon to raise the load. This rope is an endless one, passing about the pulley 5 at the tail-support, one run passing over each of the pulleys 9 and 10 at the head-support and then passing about the drum D at the engine. This drum is shown' as keyed to the shaft, although it may be provided with a friction-drive and a brake, if desired. It will be observed that in operation the run of the hoist-operating rope H between the sheave 7 and one end of the trackway will perform the function of a hoisting-ropa'while the run'of the rope H between the shea-ve 7 and the other end of the trackway will perform the function of a slackpulling rope to prevent the sagging of the hoisting-run of the rope H during the lowering of the fall. Thus in Fig. 3 the run of rope v-H shown in dotted lines at the left Yof the i sheave 7 constitutes the hoisting-rope, in fact, while the run of the rope H shown in dotted lines at the right of` thesheave 7 constitutes, vin fact, a slack-pulling rope, because1 in lowering the fall it, in fact, Outhauls thehoisting-rope, and thus supports it from sagging.

Power is communicated by any suitable mechanism from the sheave 7 to thechainwheel 8. The means herein shown consist of -the pinion 1l vand gear l2, secured to the respective shafts or so as to turn, respectively,

'A with sheavel 7 and chain-wheel 8, A chain IOO storage-drum 14: is provided, which is geared toturn with the chain hoist-wheel 8 and takes in and pays out the chain approximately as the chain-wheel 8. With the two geared together by the gears 12 and 16, as shown, the

rate of actuating the chain will vary; but the variation in rate will be accounted for in the loop which hangs between. Small guide-pulleys 13, placed one on each side of the chain close to the wheel 8,'take any side pull and prevent the chain from being pulled 0E of the chain-wheel. A clevis 15 may also be secured to the frame and one end of the chain attached thereto and a fall-block be suspended in the loop formed between said clevis and the chainwheel. This will increase the hoisting power of the device over the direct attachment of the load to the end of the chain.

In Figs. 4L and 5 a modified form is shown, in which two chain hoist and chain storage wheels arel employed, one pair on each side of the carriage, and the rope or driving wheel 7 is placed between the carriage-frames. In this construction there are two hoisting-chains I I', repectively pendent from the two parts 8 8 of the hoist on the load-carriage and connected together at the bottom by a yoke 20, which is provided at thev middle with a loadsupporting hook 21. This construction has the advantage of maintaining the load attachment 21 substantially in the vertical plane of the Wheels 1 2 even though the winding of the suspenders I I' upon the hoist parts 8 8 should vary the distance between them. Where the fall consists of only asingle suspender I, there is no means of compensating for any sidewise variation from the vertical plane of the wheels; but where the fall consists of the two suspenders II', yoked together, as in Fig. 4, it enables the two parts 8 8 of the hoist to be so constructe'd that any sidewise movement of one suspender in the course of winding or unwinding can be compensated for by an inverse sidewise movement of the other suspender, so that the resultant may maintain the load-support 21 constantly in the same vertical plane.

In connection with the engine in Fig. 1 I have shown a means for taking up slack or applying tension to the operating-ropes.:

This consists in a wheel 16', which receives one of the wraps of the rope passing about the engine-drum, said wheel being adjustable in any convenient Way toward and from the engine-drum. The means shown, although not the only means which may be used, consists in journaling the wheel in a frame 17,

which is mounted to slide on guides and is controlled in position by the threaded rod 18. At the tail end of the cableway another means 'r for adjusting tension on the ropes is shown. This consists in journaling the sheaves 5,about E which these ropes pass, in a block 6, which is 1 clamped upon the main cable A. This block g has ears for the attachment of ropes or chains by which it may be pulled back until the ropes are suiiciently tightened.

It will be noted that by the use of'a chain hoist-wheel and a chain storage-wheel theY pull of the load is always upon the same point and does not shift laterally of the direction of the cableway. In cableway-carriages containing a drum which is both a hoisting and a storing drum the position of the hoist-rope varies laterally with respect to the plane which includes the supporting-cable and is perpendicular to the hoisting-drum axis. As the hoisting-rope varies from this plane it throws a side strain upon the drum, which as the carriage is suspended tends to cause the hoisting-rope to run off the end of its drum. This tendency is suflicient to prevent the practical operation of devices of this character. The side strain has in such cases been sufficient to` make a cable climb over iianges of considerable depth.

By my invention the draft of the hoistingchain is kept at all times in a direct line beneath the supporting or trackway rope and there is no side strain tending to pull the chain off of its wheel. 'The avoidance of side draft might be secured by having the chain coil upon itself; but this would greatly vary the power of the hoist, which result would ordinarily be very objectionable; By my construction the draft is always central and the power is constant. By using a chain of sufficient length it is possible to bring in loads from a great distance in either side of the line of the cableway, thus increasing its efficiency. To take the side strain necessary to swing the carriage into line with the strain in such cases, the guide-rollers 13 are provided on each side of the chain.- These are not needed after the chain becomes strained, as then the carriage swings so that the draft is central.

While I have herein shown the storagewheel'as geared to the hoist-wheel, it is evident that it may be turned by a frictional connection therewith, in which case its speed may be varied by permitting slip, or it may be connected .directly with the wheel 7, over which the hoist-operating rope passes.'

I have only shown and described the use of a chain for hoisting purposes, not that a rope may not be used, but because a chain lends itself to use with a simple hoist mechanism of the character desired better than a rope does. A grip-wheel or double hoist-.drums might, however, be used with a rope Vinstead of the pocket-wheel and chain.

Since various features of my inventionmay be employed, omitting others, and the parts or elements may be varied to a great extent, I do not wish to be understood as limiting myself to exclude such omissions or variations.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- IOO IIO
