HOISTING, CARRYING, AND DELIVERING APPARATUS.

PECIFICATION forming part of Letters Patent No. 329,546, dated November 3, 1885.

Application filed July 2, 1885. Serial No. 170,531. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM A. FRY, a resident of Washington city, in the District of Columbia, have invented certain new and useful Improvements in Apparatus or Machinery for Hoisting, Carrying, and Delivering Heavy Bodies, such as Earth, Stone, 8vo.; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being .had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a simple, efficient, and economical apparatus whereby large and heavy bodies may belifted or hoisted, carried when raised, and deposited or delivered at the desired point-as, for instance, at another place in an excavation, or into cars, wagons,'orvessels; and it is also applicable for loading and discharging coal-vessels, lifting out of hatchways and carrying the coal to and delivering it in the coal-yard.

The special construction, arrangement, and operation of the devices will clearly appear from the following.

In the drawings, Figure I is a view in elevation illustrating an apparatus embodying my invention and in position for actual use as adapted for hoisting earth, stone, &c., from deep excavations, carrying it directly back for again filling up such excavations step by step after the underground work-such as masonry, sewers, Sta-have been progress -ively built; Fig. 2, an enlarged partial view in elevation showing the balance frame and connections and an engine supported on such frame; Fig. 3, a detail showing a clip enlarged; Fig. 4, a partial view enlarged showing the articulated carriage and its connections; Fig. 5, an edge view of one of my traversing takeup devices enlarged; Fig. 6, a drum and its connections enlarged, for tightening and holding the cable; and Fig. 7, an end view of the balance-frame.

A is a metallic or other fixed or standing rope, secured at both ends, and serving as a track for the carriage. It is either moored at both ends by anchoring in the ground, as shown at 1 in Fig. 1, or to some xed object;

or it may be so secured at one end ouly,while its other end is fastened to a frame, B, and on this frame the steam-engine 3 for working the apparatus is preferably supported. This frame B is a triangular balance-frame composed of an upright part, 4, a long horizontal part, 5, and diagonal braces 6. This frame I prefer to provide with wheels to run on a railwaytrack, as shown, and the steam or other engine is placed on one end of it, and the weight of the engine not only serves to ballast and steady the frame, but, being placed at the greatest practicable distance from that point, 7, which receives the main thrust and strain when the apparatus is at work, it effectually overcomes any tendency of the frame to be pulled over with that point as a fulcrumpoint. This arrangement also permits the frame to be put on wheelsand placed on a short railroad-track prepared for the purpose, and which greatly facilitates the shifting of both frame and engine from time to time as the work progresses and advances forward.

Two or more stationary or standing ropes, A, may be used with the same frame and engine, as found desirable; and each standing rope is provided with its own jointed or articulated carriage, C, by the aid of which the buckets 8* or other bodies are hoisted, carried and lowered, and deposited. This carriage is of peculiar construction, its frame being substantially a pendent parallelogram jointed, pivoted, or articulated at each of its four corners, 8 9 10 1I, so that when running on aninclined rope the points or corners 10 11 may hang vertically from the points 8 9 under all changes of position of this carriage on its track. The upper grooved guidewheels, 12, of this carriage run on the rope A, and the lower ones, hung at 10 l1, are used for the hoisting-rope D, which rope is clipped or fastened securely at any desired point to the rope A, whence it passes over the grooved pulley 105; thence downward to and around a grooved pulley, 13, mounted in a frame, 14, provided with a hook on which one of the buckets 8* is hung when in use, and thence upward and around pulley l1 i and thence to and over pulleys 15 16 on the balance-frame ICO B to the lifting-drum E on the bed of the en- For traversing the carriage and its suspend"- ed bucket.. or other article along the ,line of. the work, a traversing-rope, F, is employed, one end of which is connected in any suitable manner to the carriage, as shown, for instance, at

2; thence it extends to and over pulleys lZ and v 18 on the frame B, and thence t0 the drum G of the engine, the revolution of which serves to wind or unwind it at the will of the attendant at the engine. i

As I claim nothing new in the construction of the engine itself, it needV only be said here that the engineer can by any well-known means, as by simply turning a lever or otherwise, throw either or both drums into or out of gear or action at will at any time to wind or topermit the unwinding of either orboth of the ropes D or F, and thus either the hoisting or the lowering may continue either while the carriageis running or not running. The hoist;- ing or lowering may also be stopped while continuing to run, or the running oi' the car-. riage may be stopped while the hoisting or lowering is going on. Two or more hoistingcarriages, C, may be hoisted and run at the same time by simply providing two or more rope-tracks, A, and the hoisting and travers.- ing ropes as above, and guide-pulleys, one

balance-frame, B, and one engine answering for all.

H H H, dsc., represent a series or set oi' from drum 20?! of' H to a similar take-up, H,

similarly placed on the track and ropes, and a rope, I@ similarly extends from the drum on H to a similar take-up, H, and so on for the series, the rope from the last of these small drums being secured to the balance-frame B. When the traversing-.rope isin action to cause ythe carriage to dump or deliver itsl load, thev first one, 'H, of this series of devices is pushed forward by the advancing carriage@ as it. or

any projection thereon comes against it, and as it moves forward the friction of pulley.2.0 on the track A causes this pulley to. revolve, and thus winds up on its drumV 20* the rope I, which reached from it to H', and so on in succession,these devices H H, Snc. arepushed each one toward the next,l and their rope connections. I Iv I, &c., wound up, and notv leftto hang down, as otherwise they would do. I

thusA avoid all liability of their becoming in any way entangled or twisted or obstructing u the proper. action of .the apparatus. lhen the carriage C runs. back, which it wil-l-` do-by its own Agravity on an inclined track, all these devices Ii.' ,H3 kan., also run Lbalrhy their 0WD gravity, and the wound cord or rope of the one nearest the balance-frame B first runs out, stopping the device at its original place of suspension on the `track A.` Then the next oneunwinds its cord till it runs out, and so on, each one successively resuming its original place if the carriage be run back far enough. Clips K, of any appropriate kind, may be used to fasten the hoisting-rope D to the cable or rope A. Adesirable form o f such clip is shown on an enlarged scale in Fig. 3. By tightening its nuts 7c it binds and clips these ropes iirml y together as closely as may be needed. The shifting of these clips to a different position upon the rope allows the limit of descent of thel buckets, &c., to be Varied as hundred feet or more, so that when the appa- 'Y ratus is ready for working,a long range of work or of excavating and of iilling up after excavating may be done withoutneed of moving the engine and balance-frame, or of re.- moloring the rope or cable A; but when such moving is done therailway-track L may be extended accordingly over the ground last filled up. In some cases (dependent on the IOO character of the work) the cable, A need not be inclined. In such case the empty bucket-s orthe carriage may be pulled back by a cord or rope instead of by gravity. As arule,it is better to make a full hoist of the bucket. or

other article to be raised and carried before causing it to run or travel toward its: place of delivery. I tighten the cable or cables A to the required degree by means of' a, drum, M, on the frame B, and this drum may beheld from revolving by a common ratchet and pawl; but. I prefer to use a worm and gear, as shown at 231m Figs. 2 and 5. which serve` both to tighten thel cable and to lock` the drum. It willbe seen that. work may be continued almost the entire distance between the balanceframe Band the moored end 1 of cable` A before-it will be needful to shift the apparatus to a new' position. i .l

The. machine works very easily and rapidly 'and I ffnd by practical use that it. willdo the rwork of many men andl many horses and carts IIO road construction, certain kindsof tunneling,

and the like; and by shifting as desired the position of the balance-frame and engine the raised articles can be deposited at any desired point` within a. circle whose radius is equal to the distance which the carriage may travel on its cable, this rlexible cable and its connections readily permitting this, as there is no trestle-work for supporting atrack tobetaken down and rebuilt.

For many purposes therailWay-track Lmay be dispensed with-as, for instance, for discharging from vessels into Warehouses and for varieties of light work,and where the work is not a progressing one-and the flexible trackcable A may be fastened at that end where the power is applied directly to the ground or to a building or any fixed object.

I claim as my improvements in apparatus for hoisting, conveying, and delivering earth and heavy articles- 1. In combination, the metallic standing or track rope, the jointed or articulated traveling carriage C,hung thereon, the hoisting-rope D, and traversing-rope F, these parts being arranged for joint action, substantially as set forth.

2. In combination with the standing-rope A, the hoisting-rope D, adjustably fastened thereto by clips, and a traveling carriage, substantially as and for the purposes set forth.

3. In combination, the track-rope A, hoisting-rope D, fastened thereon, traversing-rope F, balance-frame B, and a steam-engine supported on such frame, all substantially as set forth.

4. In combination with the hoisting, traversing, and track ropes, and with a railway in line substantially with the course of the excavation, a railway-carriage adapted for such track, and ballasted at its rear end by the engine which operates the hoisting mechanism. 5. In combination with the track-rope A, hoisting-rope, and traversing-rope, the series of wheeled devices H H 8m., provided with Wheels 20 21 22, for running on said ropes, and connected together and to the balance-frame by cords or ropesI I', 85e., as and for the purposes set forth.

6. In combination, the track-rope, hoistingrope, traversing-rope, and a series of take-up devices H H', &c., connected as described, and each provided with a drum for automatically winding up the slack of the cords or ropes I l', &c., all substantially as set forth.
