ORE-BIN.

SPECIFICATION forming' part of Letters Patent No. 705,761, dated July 29, 1902.

Application filed May 3, 1902. Serial No. 105,798. (No model.)

T0 all whom, t `may concern,.-

Be it known that I, GEORGE H. I-IULETT, of Cleveland, in thecounty of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Ore-Bins; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in traveling ore-bins, the object being to con,u struct a bin designed to travel between the source of ore-supplyand the skip-car which carries the ore or mixture of ore, coke, and limestone to the furnace, with means whereby any given quantity of ore or other material may be positively and quickly discharged therefrom and also with. means for prevent-` ing the accidental loss of material in transit.

With these ends in view my invention con' sists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims. v

In the accompanying drawings, Figure l is a view in side elevation of a bin embodying my invention. Fig. 2 is a view in transverse section of same. Fig. 3 is an end view of a modification, and Fig. 4 is a plan view of same.

1 `represents the -bin=body, mounted on wheels 2. This bin runs on a track 3 and is divided into a series of transverse compartments Il, each of which is open at the top and provided with an inclined side 5, the latter extending from a point near the top of the body to preferably a point beyond the longitudinal center of the bin, so as to cause the material deposited in the compartments of the bin to gravitate toward the perpendicular side of thebin. This perpendicular side of the bin is provided with an opening for each compartment, the said opening starting from the bottom 7 of the Abin and eX- tending up suii'iciently to permit of the free passage of the ore therethrough, and each opening extends approximately the length of its compartment, so as to prevent any choking action when the plungers, to be hereinafter referred to, are actuated to eject the material from the compartments. l

Pivotally secured to the side sill or body of the bin is a door 8 for each compartment.

These doors are each pivoted at its lower end to the side sill or body of the bin andwhen in their upright positions, as shown in dotted lines in Fig. 2, completely close the openings in the compartments and prevent the escape of any ofthe contents. When the doors are horizontal, as shown in full lines in Fig. 2, they project out sufficiently beyond the line or angle ofrepose of ore or other material in the compartments to prev vent it fromgravitating over the ends of the doors.

Each door is connected, preferably at both ends, by chains 9,which pass over pulleys l0 and carry counterweights l1, the latter resting and moving within the spaces between the compartments. These counterweights are sufficiently heavy to hold the doors 8 in their closed positions when the compartments are empty and are suiiiciently heavy to hold the doors when the compartments are loaded and the weight of the ore or other material is against the doors at such an angle or inclination as to prevent the material from4 falling or being jarred out during the travel of the bin.

The doors 8 whenhorizontal rest in aplane with the floors of the compartments and form a continuation of the same, and located within each compartment and normally resting under the inclined side 5 of the latter are the y,

plungers 12.M Each plunger 12 is rectangular in shape `and extends from one end ofthe compartment to the other end, and each has a top plate 13, also extending throughout the length ofthe compartment and of sufficient v width to extend from a point under the lower end of the inclined side 5 to appoint near the outer end of door 8, so that when the plunger is forced outwardly this top plate, moving immediatelyunder the lower edge of the inclined side, forms a false bottom for the compartment.

Each plunger 12 is mounted .in a cylinder 14, located midway each compartment and in a plane below the inclinedside 5. These cylinders 14 are coupled up by a pipe to a com' mon source of steam, oil, or water supply and each is provided with a valve which controls the admission of liuid to the cylinder. If desired, the car Amay be provided `with a motor, pipes, and other apparatus for supplying the IOS operating medium to the cylinders, or the cylinders may be all connected to a common supply-pipe 15, carried by the car, the said supply-pipe having couplings for its attachment to a stationary source of supply, or, if preferred, rack-bar and pinions actuated by suitable motors may be employed for moving the plungers, or, as shown in Fig. 3, the cylinders may be stationary and be coupled up to the plungers carried by the bin.

With the bin thus constructed the doors S when open form continuations of the floor '7 and extend out beyond the perpendicular side of the bin sufficiently far so that the ore lying at the natural incline of repose will not gravitate over the edge thereof, hence permitting the employment of openings as high and as wide as may be necessary to insure a free passage of the ore without any clogging or arching of the ore in the bin.

I have described the improvement as applied to moving bins; but it is evident that it can be applied to stationary bins, and when applied to the latter the pivoted doors may be dispensed with and the iloor continued out to support the ore in its natural inclination. Vit-h a movable bin it is essential that pivoted doors be provided, so that they may be closed up to clear obstructions and also to prevent the material from being jarred out by the motion of the bin.

In order to discharge the contents of a compartment of the bin, the plunger is actuated to force the material out through the opening in the perpendicular side of the bin, and as the plunger is withdrawn or moved inwardly the door assumes an inclined position due tothe counterweights and remains so until again forced downwardly by the outward movement of the plunger. The advantage of this system of discharging ore from the bins over that heretofore used is that it will positively eject either crushed hard ore, coke, or limestone or very soft line wet ore. Again, it is necessary in practical use at a furnace to draw out small quantities of ore at a time into a larrie or scale-car in making up the mixtures required for making iron, and in the ordinary bins if the doors are made large enough to insure a free movement or discharge without arching or clogging the chances are that an excess of material will escape. To overcome this, various devices have been designed, none of which up to the present time have been uniformly successful; but with my apparatus, wherein the floor extends beyond the natural incline of repose of the material in the bin and is forced beyond this natural incline by plungers, the opening in the compartments can be made large enough to insure a free movement of the ore and the discharge of large or small quantities to a nicety.

It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention, and hence I would have it under stood that I do not restrict myself to the particular construction and arrangement of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
