SPECIFICATION forming part of Letters Patent No. 745,038, dated November 24, 1903.

Application tiled August 1, 1903. Serial No. 167.853. (No model.)

To ctZZ whom it may concern:

Be it known that I, EDWARD C. CARTER, a citizen ot the United States,residin g at Evanston in the county of Cook and State of Illinois, have invented certain new and useful Im provements in Ore-Docks, of which the following is a specification.

This invention relates to that class of docks which are built particularly for the purpose of storing ore and discharging the same into large vessels for the purposes of transhipment, and has particular reference to the construction and arrangement of the ore-pockets and chutes thereof, as will more fully hereinafter appear.

The principal object of the invention is to provide an ore-dock with simple, economical, and efficient ore-pockets andl attached mechanisms. Other and further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists principally in an oredock in which there are combined a pocket having an inclined bottom and a dischargeopening, door mechanism closing the same, so as to prevent or permit of the discharge of material,and a dischargechute pivotally connected to the dock adjacent to the door mechanism and of a width substantially equal to that of the ore-pocket and narrowing in width from the point of reception to the point of discharge.

The invention consists, further and finally, in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure lis a front elevation of a portion of one type of .ore-dock as it appears when constructed in accordance with these improvements; Fig. 2, a vertical sectional elevation taken on lines 2 of Figs. l and 3 looking in the direction of the arrows; Fig. 2", an enlarged plan sectional detail taken on line 2a of Fig 2; Fig. 3, a plan view, partly in section, taken on the line 3 of Fig. 2 looking in the direction of the arrow and showing the dischargingchute; Fig. ,a side elevation of the discharging-chute; and Figs. 5 and 6 are cross-sectional elevations of the discharging-chute, taken on lines 5 and 6, respectively, of Fig. 4.

' In illustrating and describing these improvements I have only illustrated and will describe that which-I consider to be new, taken in connection with so much as is old as will properly disclose the invention to others and enable those skilled in the art to practice the same, leaving out of consideration other and well-known elements, which if set forth herein would only tend to confusion, prolixity, and ambiguity.

In the art to which this invention relates it is well known that in the use of ore-docks the pockets are usually provided with but one discharge-opening, which permits the ore to be discharged from the4 bottom central portion of the pocket only. The principal objection to an ore-pocket constructed in this manner is that it permits the ore to accumulate in the lower side corners of the pocket and to form abutments by which the material is arched during the discharge of the same. In this construction, therefore, but a small portion of the material lodged in the pockets can be discharged at one operation, the result being that considerable time, labor, and ex'- pense are involved to break the arched material-generally from below-by manual labor before the remaining material can be discharged.

The principal object, therefore, of this invention is to provide an ore-dock with an ore pocket or pockets in connection with discharging-chute mechanism, all so constructed and arranged that this lodging of material in corners and arching of some in the pocket is prevented, all of which will be understood and appreciated by those skilled in the art.

In constructing an ore-dock in accordance With these improvements I build a main supporting-frame and underpinning of the dock in any desired manner well known to those skilled in the art, and which it is therefore unnecessary to further describe or illustrate herein. This ore-dock I provide with an orepocket a, having a bottom portion l), inclinn ing downwardly and outwardly toward the front wall c of the same, which is formed by a portion of the dock-framework. This liront Wall is provided opposite each pocket with two upwardly-extending posts d d, providing a discharge-opening, but really dividing it into three discharge-openings e, close-d by a bottom portion.

It is very desirable to have these doors independently and easily actuated, and for this purpose each door is made independent ofl the other and provided with gudgeons g at the upper portion of their lateral edges slidingiu grooves t' in the vertical posts. The lower part of the doors is therefore free to swing outwardly when released, and it is necessary to provide means for locking the same to prevent such movement and consequent discharge of the material until the desired time or times. In order so to do, locking-bolts j are provided, slidably mounted in straps 7s and actuated by means of an operating-lever Z. The arrangement is such that when the doors are in their closed position the locking-bolts are arranged to enter perforations in the walls of the door-platesm just outside of the pocket. As soon as the bolts are withdrawn from the locking-perforations the weight of the discharging material presses the lower end of the door outwardly, thus minimizing the resistance to raising the door, so that counterbalancing-weights n, which are connected with the upper edges of the door by means of the cable p, are readily effective to assist in raising the door or doors and uncover' one or more of the discharge-openings, so as to permit the material to pass out.

It is highly desirable to provide a dischargechute of such construction and-arrangement that it will receive all of the material passing out through either one or all of. the dischargeopenings and at the same time be of such a width at its discharge end that it can readily enter the hatchway of an adjacent vessel and prevent the spilling of material, as well as provide for the necessary bail and yoke mechanism. VIn order to accomplish these results, a discharging-chute q is provided, which is pivotally secured at its receiving end to the door-plates m, as at o, and is of a width substantially equal to that of the discharge-opening, the ore-pocket, and its inclined bottom, but which gradually narrows in width and increases in depth toward its discharge end r.

In Fig. 3 the narrowing of the width ot' the discharge-chute is seen, while in Figs. 4, 5, and 6 the gradual increasing depth of the chute can best be observed. Yoke mechanism tis provided and passed around the lower part of the chute adjacent to its discharging edge and provided with lug mechanism u, to

Iwhich`the ordinary bail (not shown) may be secured, as is usual in such instances.

I claimM y l. In an ore-dock, the combination of a pocket having an inclined bottom and a discharge-opening, door mechanism closing the same so as to prevent or permit the discharge of material, and a discharge-chute pivotally connected to the dock adjacent to and underneath the door mechanism ot a width substantially equal to that of the ore-pocket and narrowing in width from the point of reception to the point of discharge, substantially as described.

2. In an ore-dock, the combination of an ore-pocket provided with a bottom portion inclining toward the bottom and front of the pocket and with a discharge opening or openings at the lower front portion thereof, a plurality of independently-actuated doors closing such discharge-opening, and an ore-chute pivotally secured to the dock adjacent to and underneath the discharge-openings of a width substantially equal to that ot the door-openings and increasingin depth from the receiving to the discharging portion, substantially as described.

3. In an ore-dock, the combination of a pocket provided with a bottom portion inclining downwardly and forwardly toward the front of the ore-pocket and with a plurality of discharging-openings at or near the lower portion of the pocket, a plurality of independently-actuated door mechanisms for opening and closing such discharge-openings, and a dischargerl chute pivotally secured to the ore-dock adjacent to and underneath the discharge-openings of a width substantially equal to that of the discharge-openings and increasing in depth and decreasing in width from its receiving to its discharge end, substantially as described.

4. In an ore-dock, the combination of an ore-pocket provided with a downwardly and outwardly inclined bottom portion and-with a discharge-opening of substantially the width of the pocket at the lower outer end, a plurality of door mechanisms closing such dischargeopening, and an ore-chute of substantially the same width as the pocket pivotally secured to the ore-dock adjacent to and underneath such discharge-opening and gradually decreasing in width from its receiving to its discharging end, substantially as described.

5. In an ore-dock, the combination of an ore-pocket provided with a downwardly and outwardly inclined bottom portion substantially the entire width of the ore-pocket and with three dischargeopenings-one central and two side-at the lower forward end of such pocket of substantially the same width as the pocket, three independently-sliding doors i'or opening and closing such dischargeopenings, and a discharge-chute pivotally secured to the orc-dock of a width substantially equal to the pocket at its receiving end ,and gradually narrowing in width to its discharge end, substantially as described.

6. In an ore-dock, the combination of an IIO anisms attached to such door and a discharging-chute pivotally secured to the dock underneath and adjacent to the discharge-openings of a width substantially equal to the ore-pocket at its receiving end and gradually narrowing in Width and increasing in depth.

from such receiving to its discharging end, 2o

substantially as described.
