HOISTING AND CONVEYING APPARATUS.

SPECIFICATION forming part Of Letters PatentNo. 602,726, dated April 19, 1898.

Application filed December 4, 1897. Serial No. 660,823. (No model.)

T0 at whom it may concern.-

Be it known that I, JEREMIAH CAMPBELL, a citizen of the United States, residing at Chelsea, in the county of Sufiolk and State of Massachusetts, have invented a new and useful Improvement in an Apparatus for Hoisting and Conveying, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

Theinvention relates to ahoisting and conveying apparatus having a long continuous trolley-boom mounted upon and crosswise a car-truck or other support to extend any desired distance from each side thereof, combined with a single trolley and single steamshovel adapted to be used at will upon the boom upon either side of its center or upon any other part or the whole length thereof and to be transferred from one side to the other or one operative position to another without disconnecting the trolley or shovel from their operating ropes or engines, the boom, trolley, and shovel being combined with a trolley-engine and a shovel-engine, both mounted upon the car truck or support in a manner to permit the movement of the trolley, shovel, engines, and operating connections simultaneously from one operative position to another.

In the drawings, Figure 1 is a View principally in side elevation of my improved apparatus. Fig. 2 is a view in end elevation thereof. Fig. 3 is a view in horizontal section upon the dotted line 3 3 of Fig. l and in plan of parts below said line. Fig. 4 is a view, enlarged, in side elevation of the top of the tower to show the arrangement of sheaves thereon. Fig. 4 is a view in horizontal section upon the dotted line A rof Fig. 4. Fig. 5 is aview in plan, enlarged, of an engine for operating the trolley equipped with a winding-drum; and Fig. 6 is a view, enlarged, of a trolley-engine equipped with a windingspool instead of a winding-drum. Fig. '7 is a detail side view of the trolley.

A represents a car or truck having wheels a, supported by rails ct upon a trestle A or other suitable support. The car has mounted upon it a long boom or tramway B at any required distance above the floor b of the car.

The boom extends any desired distance from each side of the car and is preferably centrally attached to the car by any desired arrangement of stays Band suspending-chains B Ithas two parallel sections or parts 1) 19 which are separated from each other throughout the length of the boom, leavinga clear unobstructed space 11 between them for the travel of the shovel-operating trolley and guy-ropes.

The boom must be of a sufficient height above the bottom of the car to permit the shovel to pass between it and the bottom of the car from one side to the other, either for the purposes of transferring the shovel from one operative position to another or for con-' tinuous use crosswise the car. The boom carries tracks 0 0, upon which the trolley C is supported and upon which it is adapted to be moved from one end of the boom to the other. It is so moved by means of an engine having two winding-drums, one of which winds a draw-rope connected with the trolley to draw the trolley from the center toward one end of the boom, the second windingdrum meanwhile paying out rope, while the second winding-drum and rope operate to draw the trolley from the center of the boom in a reverse direction to the opposite end of the boom, the first-named winding-drum meanwhile paying out its rope. The winding-drums may be combined as represented in Fig. 5, if desired.

In lieu of two winding-drums an endless draw-rope wound about a spool and the ends of which are connected with the trolley may be employed, the spool being operated by the engine to turn in either direction to draw the trolley from the center outward to either end of the boom.

It will be understood that the weight of the shovel will always move the trolley from either end of the boom inward to or near the center of the boom.

The trolley-operating rope is lettered c and one section extends from the trolley to the end I) of the boom, about the sheave b thereon, backward to the sheave 17 near the center of the boom, and thence to the trolley-engine D. the trolley, about the sheave b at the end b of the boom, and then backward to the sheave The section 0 of the rope extends from 12 near the center of the boom, and thence to the winding-drum or spool of the trolleyengine.

The trolley carries the two pairs of sheaves c and the set a is used for guiding the shovel-operating ropes e e of the shovel E when the shovel is operated upon the side of the boom to the left of the car, as represented in Fig. 1, and the set 0 is used for guiding the said shovel-operating ropes when the shovel is operating upon the side of the car at the right hand of Fig. 1.

The shovel E preferably is of the clam-shell variety, and it is filled and discharged in the usual or in any well-known manner. Its operating-rope e is a hoisting and lowering rope, by means of which the shovel is hoisted and is lowered, and the rope e is actuated to close the shovel and open it. These ropes extend from the shovel over one set or the other of the trolley-sheaves c 0", according as the trolley is at one side of the center of the boom or the other, and the hoisting-rope 6 passes between the sheaves e e at the top of the tower E, (see Fig. 4,) thence over the sheave e to a winding-drum of the shovel-operating engine F. The opening and closing rope e passes between the sheaves e e and the sheave e to a winding-drum of the shoveloperating engine.

The shovel-engine is operated to wind or unwind the hoisting and lowering and the opening and closing ropes during the hoisting of the shovel and the transfer of the shovel according as the trolley is moved upon the boom, and where the trolley with the shovel passes the center of the boom from one side to the other upon passing said center it becomes necessary to pay out the hoisting and lowering and opening and closing ropes until the trolley has reached the position upon the boom at which it is desired the shovel shall be discharged of its contents. It is also necessary that the means for suspending the ropes in the tower shall be such that they may be moved by the trolley from one side of the center to the other side of the center of the boom and still maintain engagement with suitable sheaves and also be held separated and operated, and it is for this reason that the system of sheaves represented in Fig. 4 is used. Three sheaves for each rope are there represented. Two of them are in opposed relation to each other and only one of each of these pairs is used at one time, the ropes transferring automatically from the seat on one side to the seat upon the other side as the trolley passes the center of the boom. The ropes atother, and the sheave e occupying a like relation to the sheaves e a I The guy-rope G passes from the shovel over a sheave g at one end of the boom and over a sheave g in the top portion of the tower and thence downward through a sheave g on the operating-weight g and thence upward to the top of the tower, where it is fastened.

When the shovel is operating upon the opposite end of the boom from that containing the sheave g, the guy-rope then runs through the opening between the bottom of the car and the boom and over a roll 9 on the car. (See Fig. 1.)

Preferably the trolley-operating engine D is at one side of the cross-opening Z2 between the boom and the bottom of the truck or car, and the shovel-operating engine F is upon the other side thereof. Any suitable type of engine may be used. Each may be inclosed in a small house, and there may be a station upon the top of each one, a station D for the operator of the trolley and trolley-engine, the other, station F, for the operator of the shovel and shovel-operating engine. The car may also have a part of its floor shaped to form a hopper H, into which coal may be dumped and through which it may be fed to a tramcar H, movable upon the tracks h h on the trestle below the car A, or the hopper may deliver into any other desired receptacle.

While I prefer that the shovel-operating ropes and guy-ropes extend to the top of the tower and from thence to their operating engine and weight, respectively, yet they may run horizontally to turning-sheaves by which their course may be directed to the engine and to a weight below the boom. I prefer, however, to use the tower.

The shovel is operated to take up and deliver coal or other material in the manner of the ordinary clam-shell shovel, and the trolley is also operated to transfer the shovel horizontally. The apparatus differs from the ordinary hoisting device in that it is so constructed and arranged that the shovel and trolley may be used upon either side or end of a long boom and worked upon that side only, and they may be transferred from working position upon one side of the boom to working position upon the other without removing or disconnecting any part of either the shovel or trolley and by simply moving the trolley and shovel from one end of the boom across the center to the other end thereof, and they may be used for transferring coal or material from one end of the boom across the center to the'other end of the boom or from or near one end of the boom to its center, or, in fact, upon any part of the boom desired, and the boom and also the trolley and shovel-operating engines and devices are supported to be simultaneously moved by their supporting truck or car from one operative position to another at will. This enables coal or other material to be taken from fig,

any position or pile within the range of the apparatus and transferred to any other position or pile or to be loaded into tram-cars or other carriers.

The trolley-operatin g engine is constructed so that it may draw the trolley by the trolleyrope in either direction at will from the center of the boom, and the trolley-rope may, as I have above stated, be operated by a drum or by a spool, and in Fig. 5 I have shown a winding-drum for this purpose and in Fig. 6 a winding-spool. The winding-drum ofFig. 5 is in two parts, one of which is adapted to wind in one direction and the other in a re-- verse direction. The engine is constructed to drive the drum or spool in both directions and consequently has two cylinders, pistons,

and driving connections with the drum or spool. It also has appropriate mechanism for throwing the drum or spool into and out of connection with its operating-shaft at will and for reversing the engine at will and for holding the drum or spool locked or stationary at will.

Ordinarily where two engines are employed for operating the apparatus two operators are necessary, one of which controls the vertical movements of the shovel and the opening and closing thereof, and the other of which controls the horizontal position of the shovel. These operators are stationed, preferably, over the engines, as specified, and operate their respective engines by means of suitable controlling-levers.

It will be noticed that the boom is so supported and its support so constructed that there is an unobstructed space below the boom and across the car or support and also above the boom and across the car or support from one end of the boom to the other, and that therefore the trolley-shovels and their operating-ropes are free to be moved from one end of the boom across the car or other support to the other end of the boom without requiring the removal of any part of the boom, car, or support or anything above or below the boom.

In Figs. 1 and 3 there are shown upon each side of the main trestle-work A additional trestles A for supporting the tracks upon which run tram or other cars for conveying or transferring coal or other material to either side of the hoisting and conveying apparatus.

While I have described the shovel as 0perated by two ropes-namely, a hoisting-rope and an opening and closing ropeI would say that I do not confine myself to the manner of its operation, and it may be both hoisted and lowered and opened and closed bya single rope or by more than two ropes, if desired.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
