CHARLES W. HUNT, OF WEST NEW BRIGHTON, NEW YORK.
IMPROVEMENT IN ORE-HOISTS.
Specification forming part of Letters Patent No. 170,442, dated November 30, 1875 application filed April 10, 1875.
To all whom it may concern:
Be it known that I, 'OHARLEs W. HUNT, of West New Brighton, county of Richmond and State of New York, have invented new and useful Improvements in Hoists for Unloading Ore and other substances from a vessel and putting the same into cars or other receptacles, of which the following is a specification:
In the drawing accompanying this specification, Figure l is a side elevation, showing the hoist in position for use. Fig. 2 is also a side elevation, but with the track H swung back over the dock, leaving the water-way clear of all obstruction, as it is when the hoist is not in use. Fig. 3 is a front elevation, showing the position of the track H, cross-piece F, and braces E E when the hoist is not in use. It also shows the frame-work of the hoist and the position of the hinges 0 and 0 Fig. 4 is a plan, showing one of its positions when in use. The dotted lines show its position when swung back over the dock when not in use. Fig. 5 shows the support and hinge O to a larger scale.
In the drawing, A shows the vessel from which it is desired to take ore or other sub stances. H is an inclined track upon which the car or truck G runs. The track H is sup ported at its outer end by braces E E, Fig. 1, and at or near its upper end by the iron 0, (shown in Fig. 5.) The track-timbers are firmly secured to the lower ends of O at O and 0 G is a pulley or block to which the tub B is attached. D is the hoisting-rope running from the engine or horse power placed in any convenient place over the block M, thence over a loose pulley on the car G through the block 0, and the end fastened to the frame-work of the car G. L is the car into which it is proposed to put the ore to run to the bins and deposit its load. The track H has the space between the rails suited to the gage of the car Gr, the wheels of which have flanges to keep them upon the track. At each end the rails of the track H are firmly secured together. At
7 the bracket 0 are hinges secured to the permanent frame-work of the hoist at O and 0 Fig. 3, upon which, as a center, the track H turns. The outer end of the track H is supported by' the cross-piece F, which, in turn, is upheld by the braces E E, which are hinged at P P and at F F. The track H is hinged to the cross-piece F at F The arrangement of these hinges is such that horizontal lines from the vertical axis of P to F 0 to F and P to F will be equal and parallel.
It willbe seen from the above arrangement of the joints of motion that the track H can be turned on the axis 0, so that the car G can be adjusted horizontally to any point within its radius, as at G G At the same time the cross-piece F and the braces E E adjust themselves to the changed position. The car L is placed under, or nearly under, the axis 0, permitting the bucket B to be dumped into it.
The above-described arrangement of joints also permits the track H to be swung around to R over the dock, the cross-piece F, track H, and braces E E then assuming the position shown in Fig.3. When the track H is placed at any point, as at G the block M is changed to the corresponding position M to make the rope 'D lead in the direction of the track H.
The operation of the hoist is as follows: The car G is brought directly over the hatch of the vessel A; the bucket or tub Bis placed in the hold of the vessel and filled, the block 0 is hooked to the tub. The horse or engine then, starting the rope D in motion, raises the block 0, and the. tub attached, until the block 0 strikes the frame-work of the car G. The rope continuing in motion, thecar G and tub are drawn up the track H until directly over the car L, (shown in Fig. l at H,) where it is dumped. The rope D then being slackened, the car G and empty tub run down the track H until the car G strikes an obstruction, U, when the car stops. The rope continuing to slacken, the block 0 and tub attached descend perpendicularly into the hold of the vessel, when it is refilled, or another one attached, and the operation repeated. The track is secured in any position by the stay-ropes T T in an obvious manner.
Where it is desired to unload from two hatches of a vessel at one time, two hoists are built at a distance apart that will accommodate the average size of vessels that are to be unloaded. When a vessel is to be unloaded that has the hatches at a greater or less distance apart than has been calculated for, the projecting ends of the track F are moved apart or toward each other, as may be required to bring the car Gr directly over the batch of the vessel, when the unloading can go on without inconvenience.
It is evident that the inclination of the track H'or the braces E E can be greater or less than shown, as may be required, to suit the position the hoist may occupy, the particular kind of carG, or the different arrangements of the rope D that the circumstances may make it expedient to adopt. The obstruction U can be placed in any position on the track H.
I do not claim supporting the track H by the braces E E and cross-piece F; but
What 1 do claim is 1. The arrangement of the joints of motion of the track H, braces E E, and cross-piece F, substantially as described in my specification, viz., in Fig. 4.
2. The projecting track' H,swinging or turn-,
ing horizontally on an axis at or near the supporting frame-work, in combination with the traveling car G or its equivalent.
3. The support and. hinge O, in combination with the trackH, the arrangement of; these hinges being such that lines from the vertical axis of P to F and from O to F and from P
