CHARLES STEVV ART SCHENCK, OF N ElV YORK, N. Y.

COAL-ELEVATI NG ORAN E.

SPECIFICATION forming part of Letters Patent No. 425,552, dated April 15, 1890.

Application filed July 10, 1889.

To all whom it may concern.-

Be it known that 1, CHARLES STEWAR S JHE1 IOK,a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Coal- Elevating Cranes; and I do hereby declare the following to be a full, clear, and exact-description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to facilitate the transfer of coal by means of a crane from ships, canal-boats, or other sources of supply to a storing-ground. To effect this general object I employ a crane mounted on a turn-table and provided with an upwardlyinclined endless conveyor or elevator and a trough or casing therefor, the latter having gates for opening and closing apertures in its bottom at intervals, the said conveyor or elevator being directed at will to discharge at any point of a circle of large radius.

The novel features of my invention will be hereinafter more particularly described, and set forth in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of the crane embodyingmy invention, with its turn-table and supporting-frame, the bulk-head, hopper, and storing-ground. Fig. 2 represents a detail plan view of a part or the conveyor and conveyer trough or casing with attached devices. Fig. 3 represents a vertical section through the same. Fig. 4 represents, on an enlarged scale, afplan view of the devices for operating the turn-table with proximate parts. Fig. 5 represents a vertical section taken on a plane parallel to and by the side of shaft B Fig. .6, the shafts and gearing being shown in elevation. Fig. 6 represents a plan view of the turn-table, its guard, the elevator-shoe, a part of the elevator, and the devices for driving the latter and supporting it. Fig. 7 represents a detail side elevation of said devices, the said guard being broken away in part to show sundry details of the tightening devices. Fig. 8 represents a detail sectional view, still further enlarged, taken on a plane parallel to and by the side of shaft L, Fig. 5, through a part of the turn-table frame and devices Serial No. 317,061. (No model.)

therein. It is practically a mere enlargement of the right-hand part of Fig. 5. Fig. 9 represents a detail view in cross-section through the discharge-spout of the -conveyer on the line 0000, Fig. 1. Fig. 10 represents a part of the same in longitudinal vertical section. Fig. 11 represents the same in longitudinal horizontal section. Figs.12 and 13 represent additional detail views of the clutch mechanism and shifting devices of the shafts.

In the aforesaid drawings, A designates a turn-table provided with standards B and an opening 0. The said standards receive and support. bearings B, which receive hollow trunnions, hereinafter described, in which is journaled a short horizontal shaft B provided with a sprocket-wheel B for engaging and actuating the chains c of an endless conve yer E. An upright pole D is set into said opening 0, and provided with stays D and a fixed platform D having on it awindlass or drum D From this Windlass a cable (6 passes to and over a pulley in a block cl, hung to the upper end of said upright, and thence obliquely downward to a chain c, attached to the casing E of the conveyer. This cable and this chain may be duplicated, as shown. By means of said drum and cable the elevator or conveyer may be raised and lowered as desired/the lower end thereof turning on shaft 13 The chains 6 are'provided with plates or blades 6 at right angles to them, which carry the coal upward in the usual way to the discharge-spout F. The coal is supplied to said conveyor near the lowest point thereof by a flexible tube G, descending from a hopper H, into which the coal is poured in unloading the vessels.

In the bottom of the conveyor casing or trough E are gates E moving endwise in guides E Each gate closes or opens at will an aperture in the bottom of said trough or casing, and to that end is operated by alever E pivoted at c to an attachment of said casing, said lever havinga longitudinal slot c in its lower part and receiving therein a stud 6 which extends laterally from said gate. The coal is carried by the upper run of the endless conveyer chain c and discharged through the spout F; but some particles of coal and coald ust will return with the lower.

run of said elevator-chain, and if not allowed to escape from the elevator-casing will clog the action of said chain. By opening one or more ofthe gates aforesaid this material is allowed to escape. In some instances, especially in case of a temporary partial obstruction of the spout, a considerable amount of coal may thus return to be dropped by said gates. The said 'conveyer is driven by a steamengine or other suitable motor and by a main shaft J, directly connected to said motor. This main shaft carries a fly-wheel J and a bevel gear-wheel J the latter driving a similar wheel 70 on an upright shaft K, carrying another bevel gear-wheel 7a, which in turn drives a similar wheel Z on a horizontal shaft L, carrying anotherbevel gear-wheel Z. This latter drives yet another bevel gear-wheel m on an upright shaft M, carrying another bevel gear-wheel 'm', which drives a similar wheel "m loose on shaft 13 aforesaid. The gear-wheels J 2 k 70' Z Z 117. 0% m hereinbefore mentioned, may be friction gear-wheels, as shown in the drawings, although it will often be preferable to provide them with teeth in view of the heavy work to be done. This wheel m may be locked at will to its shaft in the ordinary manner, so that both will turn together by means of a clutch-pulley m splined on said shaft, as shown in Fig. 12. This clutch is operated in the usual waybya shifting-lever N, which has alongitudin al slot n, receivingapin n, extending laterally from said clutch-pulley. Said shifting-lever is pivoted at its lower end toa lug n on turn-table A. The main shaft and the first upright shaft are journaled in the supporting-frame O of the structure. Said upright shaft is exactly in line with the center of the turn-table, so that the turning of the latter will not disengage the wheels 70 and Z. main shaft also causethe rotation of the turntable, the horizontal shaft L being provided with a gear-wheel L, which meshes with the teeth of a circular rack P, that is fixed on frame 0. This wheel L is loose on shaft L, except when locked by a clutch-pulley P and its shifting-lever P The operation of clutch ing and unelutching is substantially identical with that already described for shaft B A circular guard-frame Q, fast on supporting frame or platform 0, surrounds said turn-table, and is provided on its inner face at the bottomvvith a metal ring Q, having a shoulder q, overlapped by a similar shoulder 'r on a ring R, attached to the outside of said turntable to prevent the latter from rising out of its proper position. Said turn-table rests, as usual, on conoidal anti-friction rollers s, which are located Within a channel formedby two circular corresponding facing-plates S and S, the former being attached to the turn-table, the latter to the supporting-frame.

Thefollowing devices are used for taking up'the slack of the endless elevating chain e At their upper ends these pass over a sprocket-wheel 13, similar to B, but having 15 longitudinally of said elevator.

The same motor and the bearings t of its shaft tmovable on guides A bifurcated adj usting-rod T takes hold of said shaft on each side of said sprocketwvheel and is The operation of the 'crane is as follows: The elevator E being properlytightened and The lower end of said elevator is pro the coal supplied steadily through hopper, H, the clutches are shifted to engageand the steam-engine or other motor put at work.

The gearing hereinbefore described will then cause the turn-table and everything thereon to move in a partial rotation, sweeping the discharge-spout over said storage-ground in a circle of shorter or longer radius, according to the elevation given said spout. At the same time the coal is continuouslydelivered through it; or theshaft B may be kept out of action by unclutching until the desired point is reached, andthe pinion driving the turn table shifted out of action in the same way. The coal will then be delivered at one point.

of the storingground only as soon as the;

shaft B wis again clutched for operation. By reversing the engine the sweep. of the elevator is reversed also,

sive storing-ground very neatly, exactly, and quickly to any degree and to arrange differ-, ent grades and kinds of coal severally. with convenience. The gates under the elevator are particularlyimportant in insuring its, work without clogging.

r05 I Thesedevicesenable me to fill any part or all parts of an exten-,

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

1. In coal elevating and delivering mechanism, a rotary turn-table and gearing for operating the same, in combinationwith a crane mounted on and turning with said table,

an endless elevator, its closed casing hinged at the lower'end to supports on said turntable for motion in a vertical plane, connec: tions between said crane and said elevator for raising and lowering the upper and outer end thereof, a hopper arranged'to discharge into the lower end of said elevator, and a spout on the upper and outer end ofsaid elevator for delivering the coal,-substantially as set forth.

2. In combination with a closed casingand an endless elevator traveling therein, guides E attached to the sides of said casing at thev bottom thereof, gates E sliding in said guides longitudinally of said casing, each gate closing an opening in the bottom of the latter and being provided with a lateral arm 6 levers pivoted on arms a of said elevator-casing, each lever being provided with a slot 6 in its lower end, which receives the end of the arm 6 of one of said gates, a hopper for supplying coal to one end of said elevator, a spout for discharging it from the other end thereof, and

anti-friction rollers s in said channel, the fixed annular rack P, the pinion L, engaging said rack, the shaft L, jonrn aled in attachments of said turntable, the main shaft and gearing by which shaft L is driven, an endless elevating-chain and easing carried by said turntable, sprocket-Wheels over which said chain passes, a shaft M and gearing connecting the shaft L aforesaid With the shaft of the lower sprocket-Wheel, and clutching devices whereby the main shaft is allowed to operate the turntable only or the elevating-chain only, or both together, as may be desired;

In testimony whereof I affix my signature in presence of two Witnesses.
