o'r'ro ELIAS BARENE, on NEW YORK, N. Y.

COAL-GONVEYER.

To all whom it may concern Be it known that I, Orro E. BARENE, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Coal-Conveyer, of which the following is a full, clear, and exact description.

This invention relates to conveyors or apparatus for handling coal or other articles of merchandise in bulk.

Among the objects of this invention is to provide a conveyer of the class indicated including an endless series of buckets and adapted for free operation in any position of adjustment with respect to movement laterally around a vertical axis or with respect to vertical adjustment parallel to said axis.

The foregoing and many other objects of the invention and also the means for accomplishing the same will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a side elevation of the conveyer shown in operative relation to a scow or barge; Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 3; Fig. 3 is a transverse section on the line 33 of Fig. 2; Fig. 4 is a sectional detail 011 the line 1-1 of Fig. 1; and Fig. 5 is a transverse section on the line 5-5 of Fig. 4.

The several parts of this apparatus may be made of any suitable materials and the relative sizes and proportions, as well as the general design thereof, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed.

By way of illustration of a preferred embodiment of the invention, I show a stationary framework understood to be located at or upon a wharf or adjacent a railway track and including a foot piece 10 and a head piece 11 in vertical alinement with each other. The main portion of the conveyer comprises a rigid frame 12 including a vertical mast 13, an inclined boom 14 and a horizontal brace 15. The mast 13is pivoted at 10 and 11 to the fixed support members aforesaid and hence is adapted to swing laterally around the axis of said pivots. The parts of the frame 12 are preferably Specification of Letters Patent.

constructed of channel members and in duplicate as indicated, for instance, in Figs. 1 and 5, the two parts of each member being spaced from each other in parallel relation. The brace 15 at its inner end is extended beyond the mast 13 and may serve as a platform for any suitable type of motor 16 or other machinery.

As above intimated, the conveyor includes an endless series of buckets 17, each bucket being connected to and suspended between a pair of endless chains 18. The chains may be of any suitable or conventional construction and are operated over suitably arranged sprocket wheels, a pair 19 of such wheels being journaled adjacent the top of the mast 13 upon a power shaft 20 adapted to be driven from the motor 16 by means of a belt 21 operating from the motor shaft over a speed reduction pulley 22 connected to tie power shaft 20. Since the motor is mounted upon the platform constituting a part of the frame 12, the motor shaft and power shaft will always be maintained in proper operative relation irrespective of the lateral swing or adjustment of the conveyer.

The conveyer buckets 17 may be of any suitable form and are mounted between the chains 18 preferably in a certain definite or fixed relation as distinguished from buckets which are pivoted to their carrying chains and adapted for normal upright position. The loops of the chains remote from the sprocket wheels 19 are guided along or within a boot 23 at the bottom of which are mounted a pair of sprocket wheels 24 serving to guide the buckets 17 around the said bottom for the proper cooperation of the buckets for filling with the openings at the sides of said bottom. Said openings may be varied in extent, if desired, by the use of slides 25 shown in Fig. 2. The chains also are guided on the inner sides of the boot along channel guideways 26 whereby the buckets are kept properly spaced from one another and the sides of the boot. It will be understood that the boot may be shifted about in any direction with respect to the bottom of the scow S without materially interfering with the operation of the conveyor chains or buckets, especially with reference to lines radial with respect to the axis of the frame 12. Movement laterally of said radial planes is provided for by the lateral swing of the frame.

In order to compensate for variations in tide when the conveyer is employed for unloading scows or barges, and also to provide for variations in depth of the vessels or carriers to be unloaded, I make the boot adjustable vertically in the following simple manner: The boom 14 extends upwardly and outwardly from the bottom of the mast 13 at a substantially 45 degree angle which gives a spacing effect for the boot 23 outwardly from the foot piece 10 as well as providing for the vertical movements required. A trolley 27 comprising a yoke :28 and rollers 29 is adjustable longitudinally along the channels constituting the boom 14. Pairs of idler sprocket wheels 30 and 31 are carried by said trolley 27 preferably upon the same axes as the rollers 29. Said pairs of idler sprockets guide the ascending and descending runs of the conveyer chains, and by shifting the position of the trolley along the boom 14 I provide for a variation in elevation or depression of the boot, the relation of the power end of the conveyer re maining practically unchanged. As a suitable means to control the position of the trolley and hence the elevation of the boot, I provide a counterweight 32 having a chain or cable 33 extending thence over a drum 3% adjacent the top of the mast l3 and thence outwardly over a pulley 35 at the upper end of the boom and thence extending clownwardly to its point of connection 36 with the yoke 28. The boot may be manipulated in any suitable way, either by hand or by a crank 37, and the position thereof may be controlled, if desired, by means of a pawl 38 operating upon a ratchet 39, it being under stood that the counterweight may have any desired heft with respect to the weight of the boot and parts associated therewith.

When the conveyer is operated in the direction of the arrows, and the boot is inserted into the mass of material to be elevated, the buckets will automatically fill as they pass the bottom of the boot and the material therein will be carried upwardly and inwardly and be deposited, as the buckets swing upwardly, into any suitable form of chute 40 for delivery into a car, wagon or other receptacle. The weight of the boot will always insure proper tension upon the conveyor chains.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a coal conveyer, the combination of an upright frame including an inclined boom, a conveyer including an endless chain of buckets, one end of the conveyer being connected to a fixed point on the frame, the opposite end of the conveyer being suspended below the boom, a member movable along said boom and cooperating with the intermediate portion of the conveyer for varying i the position of the suspended end thereof, a counterbalance for said member and the portion of the conveyer suspended therefrom, said counterbalance including a flexible connection operating over the vertical frame and along said boom, and means associated with the fixed end of the conveyer for operating the endless chain of buckets in a uniform manner irrespectve of the position of adjustment of the opposite end thereof.

2. In a coal conveyer, the combination of a main frame, means to support the same in a vertical position, an endless conveyer comprising a pair of spaced chains and a series of buckets rigidly connected thereto and between the same, a power shaft j ournaled upon said frame, a motor to drive the power shaft aforesaid, a pair of sprocket wheels connected to said power shaft and through which the conveyer chains are operated from the motor, the buckets remote from the power shaft being adapted to automatically fill with bulk material, and means to vary the position of the intermediate portions of the chains with respect to the frame, said means comprising a trolley, idler sprocket wheels mounted thereon and cooperating with said chains, a counterweight, a flexible connection between the trolley and counterweight, and means to control the operation of the trolley and counterweight, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

OTTO ELIAS BARENE.
