CARRYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 516,084, dated March 6, 1894. Application filed October 30, 1893. Serial No. 489,472- (No model.)

To aZZ whom it may concern:

, Be it known that 1, JAMES G. DELANEY, a citizen of the United States, residing at New York, in the State of New York, have invented certain new and useful Improvements in Conveying Apparatus, of which I do declare the following to be a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.

My present invention, while applicable in part to other types of conveying apparatus, has relation more particularly to that type in which asuspended cableway is employed as a means for hoisting and conveying skips or like load carriers from point to point and in which provision is made for dumping the loaded skips. This class of cableway conveying apparatus is particularly well adapted for bridge building, open pit mining, quarrying, sewer and canal excavation and like work and is in a very general use for such purposes. In the construction of this type of cableways it is customary to sustain the cableway by means of a tower or towers set at opposite sides of the work, over which passes the main sustaining cable the ends of which are securely anchored. Upon this main cable travels a load carriage to which is attached an endless or traversing cable that passes over sheaves upon the tower or towers and around a winding drum of the engine that is located adjacent one of the towers. It is the common practice to connect to this lead carriage one end of a hoisting or .fall rope that serves to sustain a fall block beneath the carriage to which fall block the skip is suitably attached and the opposite end of this hoisting or fall rope passes over the tower adjacent the engine and around a winding drum of the engine. By means of the endless rope or cable the load carriage can be drawn back and forth along the cableway or track and by means of the hoisting or fall rope and fall block the skip can be raised and lowered as desired. It has heretofore been the practice also to attach to the load carriage a third rope or cable known as the dump rope whereby one end of the skip may be raised in order to discharge its load and this dump rope is also passed over the tower adjacent the engine and is connected to a suitable winding drum thereof.

In the operation of the above described apparatus, it is the common practice after the skip has been loaded and hoisted, to uniformly wind upon the drums of the engine the hoisting or fall rope, the endless or traversing rope and the dump rope, until the load carriage is brought to the point at which the load is to be dumped and when this point is reached it is customary to stop the traversing or endless rope and then by reversing the engine, unwind and pay out the hoisting or fall rope while checking the movement of the dump rope, thereby permitting the fall block to descend and so incline the skip until its load is discharged.

My present invention has for its object to enable the skip to be so inclined as itis hauled in to the dumping point, that when such point is reached, the load of the skip will be discharged without the necessity of arresting either of the ropes or of stopping and lowering the skip. This object of invention is accomplished, (and herein the invention broadly resides,) by providing suitable means whereby a differential drawing in of the hauling cable and the dump cable can be effected in order to impart a difference in travel to said cables for the purpose of efiecting the dumping of the load of the skip, as it is drawn inward.

It is manifest that in carrying out the broad feature of my invention any suitable means may be employed whereby a differential drawing in of the hauling cable and dump cables can be efiected, but in the preferred form of my invention I employ for one of these cables a drum having a section differing in diameter from the section on which the main body of the cable is wound in order to enable a variation in the speed of travel of the cable to be secured at the propertime. I do not wish the broad feature of my invention to be understood however, as restricted to th e particular means shown whereby the differential drawing in of the hauling cable and dump cable is eifected for the purpose of discharging the load of the skip, since many ways of efiecting a diderential drawing in of the cables to secure the dumping of the skip in transit may suggest themselves to the skilled mechanic.

My invention presents the first instance, so

far as I am aware, in which it has been proposed to effect the dumping of a skip in transit by differentially drawing in the hauling and dump cables and I wish my claims as 5 hereinafter expressed to be understood as commensurate in scope with my invention.

Figure 1 is a diagrammatic view of a cableway excavating apparatus equipped with my improvements. Fig. 2 is a plan view showing such parts of the hoisting engine as are necessary to the illustration of myinvention. Fig. 3 is an enlarged detail view of a portion of the cableway showing the load carriage thereon and showing the fall block and skip beneath such carriage. Fig. 4 is a view in side elevation of a part of the cableway showing one of the fall rope carriers in place thereon. Fig. 5 is a front view of one of my improved fall rope carriers.

A and A designate the towers by which the cableway is suspended in usual manner, and B designates the engine whereby the winding of the ropes or cables is effected. The cableway is shown as comprising a main or sustaining cable 0, a traversing or endless cable D, a hoisting rope or cable E, a dump rope or cable F and a button rope G, the ropes with the exception of the main cable and but ton rope passing over appropriate sheaves upon the towers A and A.

H designates the load carriage that is furnished with the usual traveling wheels 71 that rest upon the main cable C.

Within the main frame of the load carriage H are journaled the sheaves e and f over which pass respectively the hoisting or fall rope or cable E and the dump rope or cable F, one end of the hoisting or fall rope E being connected to the load carriage as at e and one end of the dump rope or cable F being fastened to the load carriage as at f. The dump rope or cable E sustains the fall block K, to the hook is of which are attached the chains k that support the skip L. The dump rope or cable F passes around a sheave f jou rnaled at one end of the skip L and thence upward and over the sheave fand the tower A to the hoisting engine B.

The engine B comprises the usual winding drum or pulley B whereby the endless or traversing rope or cable is driven and comprises also a drum or winding section B for the fall or hoisting rope, and a similar drum or section B for the dump rope or cable, the ends of these ropes or cables being attached to their appropriate drums or drum sections. I have shown the drums or drum sections B and B as divided by an annular flange (7 although this is not essential.

From the construction of the parts as thus far defined it will be seen that when revolution is imparted to the winding drums B and B and to the drum B of the endless or traversing rope or cable, the hoisting or fall rope E and the dump rope F will be wound at uniform speed as the carriage is; moved along the cableway and toward the engine.

In order to efiect the dumping of the skip L when it has reached the proper pointfor such purpose I make provision whereby a different rate of travel may be imparted to the hoisting or fall rope and to the dump rope, so that the skip which has thus far been maintained in horizontal position may be tilted in order to discharge its load. Without departing from the spirit of my invention this variation in the rate of travel of the two ropes may be effected in any convenient manner, as for example by providing that part of one of the cables, preferably the dumping cable,

shall be wound around a body of larger diam eter than the remaining part of such cable, the difference in the diameter or size of the body around which part of such cable is wound.

being effected in any convenient manner.

In the preferred form of my invention I provide a supplemental drum or drum section B adjacent the drum B for the dump rope, this drum B beingof somewhat greater diameter than the drum B so that when the dump rope is shifted from the drum B onto the drum B a more rapid winding of the dump rope will occur therebylifting the end of the skip L and causing the load to discharge therefrom. Preferably the annular ring or flange b that extends between the drum sections B and B is furnished with notches or cut-away spaces b to permit the ready passage of the dump rope F from the drum B on to the drum B and in order to cause the rope F to pass from one drum to the other,I prefer to employasuitable shifter M such for example as that illustrated in Fig. 2 of the drawings. The shifter M is shown as comprising the slide bar 'm that carries the rollers m and is mounted in manner free to move back and forth within the brackets m that are carried by a suitable supporting bar or frame m this bar or frame m being preferably located at a slight distance above the level of the engine. The slide bar m being mounted in manner free to move back and forth will shift automatically with the winding and the unwinding of the dump rope or cable F, but when it is desired to throw the cable F from the drum B on to the drum 'B, the bar m/will be shifted to the extreme position shown by dotted lines in Fig. 2 so as to cause the cable F to pass on to the supplemental drum 13. Preferably the slide bar m has connected thereto a pivoted bell crank lever N to the opposite arm of which is attached a shifting rod N that leads to the front of the engine where it will be in convenient reach of the operator. Hence, it will be seen that when the skip Lis to be dumped, it is only necessary for the operator at the engine to throw thedump rope F from the drum B on to the drum B as the skip approaches the point at which the load is to be discharged, thereby causing the dump rope to be wound up more rapidly than the hoisting or fall rope and so raising the end of the skip L as to discharge the load. Upon the main cable G is mounted my improved fall rope carrier P, it being understood of course that any desired number of these carriers will be employed, corresponding to the length of the cableway. Between the bars of the carrier P is journaled the roller 10 that travels upon the main cable 0 and at the lower end of the carrier P are journaled the rollers p and above these is the roller 19?, rollers 19 serving to sustain the endless and the hoisting or fall rope and the roller 19 serving for the dump cable. At the top of the carrier P are journaled the rollers 19 between which extends the button rope G" that is furnished with buttons g in the usual manner. The rollers 19 will be fixed at different distances apart upon the various carriers so that the carriers will be distributed at proper points along the cableway.

By providing the carrier P with the rollers 7) and 10 these carriers will travel freely down the catenary curve of the cableway, following closely to load carriage H in its descent and it is obvious that as each carrier P reaches its appropriate button g it will be arrested, thereby, and at such point the rollers 10' and 2 will serve to sustain the several cables. When the direction of travel of the load carriage H is reversed, it is obvious that the fall rope carriers P will be gathered up in readi ness to again descend the cableway when the load carriage is again drawn outward. By providing the fall rope carrier 1 with the rollers p and 9 it will be seen that the necessity for employing a horn or arm upon the load carriage to gather up and distribute the carriers is unnecessary.

It is manifest that the details of construction above set out may be varied within wide limits without departing from the spirit of my invention and to such details therefore,l do not wish my invention to be understood as restricted.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-
