Interposed in thehauling-rope 31 and forming a part of it is the main-tramway carriage or carriage for supporting the hoisting devices. In Fig. 1 this main-tramway carriage is shown as at the station where the excavation is being made and from which the material excavated is to be transported. In Fig. 1 the same carriage is shown as moved along the line to the point of dumping or discharging of the hoistingbuckets. In the form shown the carriage consists of a series of pairs of wheels 36, mounted upon journals 37, said wheels being grooved to rest upon the Wire-rope tram-tracks 23. The wheel-journals 37 are connected together by tie-bars 38, through which said journals pass loosely. Upon the journals 37 are also hung loosely the vertical hangers 39, within whose lower ends are looselyjournalcd the hoisting-sheaves 40. These hoisting-sheaves are in like manner connected together by tie-bars 41, through which the hoisting-sheave journals pass loosely, and from the journal of each hoistingsheave diagonal braces 42 extend to and loosely encircle the journal 37 of the next succeeding pair of tram-wheels 36. The purpose of giving this jointed structure to the framework of thetramway-carriage is to permit it to pass over the rigid supports afforded by the grooved shoes 27 without having the tram-wheels 36 leave the cable tram-tracks. In practice, however taut the cable tramtracks 23 may be originally, the weight of the tramway-carriage when loaded will cause more or less depression of said tracks bet ween the points of support, as is indicated in Fig. 1. This depression would tend to cause the advance wheels of the carriage to leave the cable tram-track in passing over and beyond a support were it not for the jointed structure of the carriage, which permits the jointed sections of the carriage to accommodate themselves to the changes of level. It will be noted that the hoisting-sheaves sustaining the hoisting-bucket 43 are located immediately below the center of gravity of the corresponding tram-wheels 36, and consequently aid as weights in retaining said wheels upon the tram-tracks.

Upon the winding-drum is Wound a hoistin'g-rope 44, which, passing over the sheave 45 of the standard 20, is provided with four continuations connected at a common point 46 and supporting the corresponding hoistingbuckets 43. The function of this hoistingrope is to permit the buckets43 to be lowered into the excavation and filled thereat, and

subsequently to hoist them out of the excavation, and to a sufficient height above the ground to be readily transported. along the line to the point of discharge by the carriage supportingthem. Itis evident that for the purpose of raising and lowering the hoisting-buckets the hoisting-drum 30 should be operated separately from and independently of the haulingrope, actuating-sheave, or live-pulley 29. When, however, the buckets in the elevated position are to be transported by the haulingrope to the discharge or dumping station, it is apparent that the hoisting-rope should be fed or paid out at the same rate of speed as the hauling-rope, in order that the height of the hoisting-buckets above the ground during transport shall remain unchanged. To this end we have provided means for engaging the hauling-rope with the hoisting-rope after the buckets have been elevated, so that as the hauling-rope is operated to carry along the buckets the hoisting-rope will be paid off from the drum 30 at a corresponding speed. The means referred to consist of a stop-block 47, fixed upon the hoisting-rope and adapted to engage with a locking catch or projection moving with the hauling-rope. In the form shown in the drawings the projection referred to is a gravity-catch 48, forked at itslower end to straddle the hoisting-rope and adapted to abut against the stop-block 47 when said gravity-catch is in the lowered position. The gravity-catch is mounted to slide freely within guides made in the frame-work of an auxiliary tramway carriage or truck connected in and forming a part of the hauling-rope. Said auxiliary carriage is provided with front and rear pairs of tram-track wheels 50, connected together by tie-bars 49, and having converging diagonal hangers 51 connected together by cross-braces 52 and supporting a grooved Wheel 53, which underruns the hoisting-rope and is weighted by the depending balance 54.

The gravity-catch 48 is provided with a slotor recess 55 for the engagement of a liftinglever 56, whose actuating-cord 57 extends back along the line and is under the control of the operator, so that by pulling upon the cord the gravity-catch may be lifted out of the path of the block 47, or by releasing the cord the gravity-catch may be dropped into engagement with said block. When at the excavating-station the hoisting-buckets have been filled, they are then raised by the hoistingrope until the block 47 abuts against, raises, and passes the gravity-catch 48, which thereupon drops again into engaging position. The stress exerted upon the hoisting-rope by the buckets and their contents is now permitted to draw back the block 47 firmly against the gravity-catch. The hauling-rope is then actuated to draw the main tramway-carriage toward the dumping-station, and during this movement of transportation the hoisting-rope moves correspondingly, being constantly paid off from its drum 30 by reason of the weight of the buckets and their contents. It is evident that because of the engagement of the block 47 and gravity-catch 48 the hoisting-rope cannot pay off or move faster than the hauling-rope; but it is limited to move at a cor responding rate of speed, so that during IIO . transport the height of the buckets above the the excavating-station to the dumping-station it is evident that the hoisting-rope would be liable to sag unless sustained by supports along the line. It is impracticable, however,

to provide permanent supports for that pur pose, inasmuch as such supports would be in, the line of movement of the carriage and would obstruct its path. To obviate this difficulty we employ a series of removable supports for the hoisting-rope so located, constructed, and

arranged with respect to each other and the remaining parts of the organization that, as

the buckets travel toward the dumping-station, the removable supports for the hoistingrope are successively, one after another, deposited along the line in rear of the traveling carriage at the intermediate supports, and so that on the return of the traveling carriage the said removable support will be successively gathered up and removed from the path of the returning carriage. In the form shown the removable supports consist each of a cross rod or journal 58, from which depend two cheek-pieces 59, between whose lower ends is mounted a friction-roller 60. The space between the cheek-pieces59 is open, so as to receive the prong or forward projection of a horn (51 connected to the auxiliary hauling-rope carriage. The cross-piece orjournal 58 of each of these removable supports is adapted to rest in open bearings 62, mounted upon the intermediate standards 22,asindicated in Fig.4. These bearings occupy a corresponding position at each intermediate standard, but are spaced apart at a progressively-inereasing distance with respect to each other from the most distant intermediate standard 22 to the intermediate standard nearest to the power-stationthat is, assuming the open bearings at the intermediate standard 22 nearest the power-station to be certain distance apart the open bearings of the next succeeding intermediate standard would be at a less distance apart, and so on progressively to the final intermediate standard. The length of the journal or cross-pieces 58 of the series of the movable supports varies in like manner and ratio. Assuming the removable supports to be within their respective bearings and that the hoisting-buckets and consequently the auxiliary carriage is at the remote end of the line with respect to the power-station, said carriage in moving toward the power-station would by means of the horn 61 successively take up and remove the removable supports from in front of the advancingmain tramwaycarriage and would arrange the removable supports upon the horn 61, as indicated in Figs. 1 and 9. To insure a closer and more compact arrangement of the removable sup ports upon thehorn, we make the cheek-pieces 59 of the several supports of unequal length, as shown in Figs. 1 and 9, so that the frictionrollers 60 will be in different horizontal planes. On the return movement of the buckets toward the dumping-station the auxiliary carriage drops the removable hoisting-rope supports at their proper posts, the removable support having thelongest cross-piece or journal being caught by the more widely-spaced open bearings of the intermediate standard through which the auxiliary carriage first passes, and so on to the last intermediate standard through which the auxiliary carriage passes.

While we have illustrated and described our improvements principally with relation to the excavation of earth and its transportation to a dumping-station, it will of course be understood that we do not restrict ourselves to such employment of the various features of our improvements, but contemplate the employment of the several devices for analogous objects and indeed for all useful purposes to which they may be severally or jointly applicable. Nor do we limit ourselves to the exact construction of the various details, butintend to employ such equivalents therefor as fairly fall within the scope and spirit of the invention.

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