ORE-CHUTE AND TRAP-DOOR.
SPECIFICATION forming part of LettersIPatent N 0. 700,789, dated May 27, 1902.
Application filed December 27. 1901- Serial No. 87,508. (No model.)
To all whom, it may concern.-
Be it known that we, JOHN A. LINDALL and NILS MATTSON, citizens of the United States, residing at Two Harbors, in the county of Lake and State of Minnesota, have invented certain new and useful Improvements in Ore- Ohutes and Trap-Doors; and we do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
The object of our invention is to provide a new and improved attachment for the opening and closing of passages leading from pockets or receptacles to spouts or ore-chutes and to regulate the flow of coal, ore, or other materials which are usually loaded from one receptacle to another by way of spouts or chutes which is simple in construction and serves to increase or diminish the flow of ore or other substance from one receptacle to another by the means of opening or closing the passage through which same is to pass.
The invention consists of certain 'parts which will be described hereinafter and then pointed out in the claims. 1
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a top plan view of a receptacle in which any material may be placed whichit is intended to transfer by way of spout or chute to a vessel or car, said figure also showing the top View of our improved mechanism for the opening and closing of the outlet from said pocket and the upper end of the rod used for loosening of the ore in the pocket. Fig. 2 is a bottom plan View of a pocket or other receptacle, showing th e'doors or gates closed by full lines and open by dotted lines'and beinga transverse sectional view of Fig. 3 on lines m as. Fig. 3 is a bottom plan View of a receptacle,usually an ore-dock or an elevator, showing our improved opening and closing attach ment applied and the rod extending down into the receptacle usually employed in loosening the materials in the pocket, the outlet from the pocket being closed by means of doors 7) b.
Fig. 4 is an enlarged View of the rod used for loosening of the ore extending down through the upper deck, at which end a lever may be applied projecting down in the pocket and engaging a bracket placed at any suitable place over the doors used for the regulating of the flow of ore from the pocket. Fig. 5 is an end elevation of Fig. 4.
The invention consists of the following partsmamely: two operating cranks,two doors for the opening and closing of the outlet from the pocket, one shaker rod with suitable brackets, three cog-wheels properly mounted rods extending from the top of the receptacle down to the lower part thereof, the regulatingdoors being secured on the said rods and suitable pegs or projections being made a part of the doors for loosening of the materials in the pocket when the said doors are opened.
The arrangement and construction of the mechanism are as follows: Two iron rods a a are preferably put in, extending down to the lower edge of the pocket,where same are properly secured to some suitable timbers. Two suitable doors I) b are secured at the lower end of said rods, said doors being provided with suitable pegs or projections c a. At the upper end of said rods a a suitable cogwheels (1 d are secured. Said cog-wheels interpose each other and are operated by a crank or lever 6. One of said cog-Wheels also interposes another small cog-Wheelfimounted at any suitable place and secured on a rod or bracket g. 'Said cog-wheel may be operated by a crank or lever j. A suitable stopper h is provided, into which lever e may be placed when it is desired to keep the doors closed. Shaker-bar t' is preferably placed close to the outer side of the pocket and made in such proportion that the upper end projects through the top of the pocket, ,where a levermay be applied ,to thesame, and that part of the bar provided with the projections is placed un der the cover of the pocket and extending down to withina few inchesfrom the upper edge of the trap-doors, where said shaker-rod interposes a bracket which acts as support for said shaker-rod.
The operation is as follows: When it is desired to open the mechanism from its normal position, as shown in Fig. 3, lever 6 may be on suitable rods or brackets, and suitable moved in the direction shown by the arrow in Fig. 1, which operates the cog-wheels cl d. Said cog-Wheels operate rods a (L and doors I) 12, secured to the said rods, and the doors will open and allow the ore to pass through. In opening the said doors pegs c 0 will engage the materials in the pocket and have a tendency to loosen the same. If for any reason it should be deemed desirable to stop or regulate the flow from the pocket before same is empty, cog-wheel (1 may be operated by means of lever j, said cog-wheel being made quite small and the lever being made long in proportion, so that a complete stoppage of the flow of materials may take place. If for any reason the ore or materials placed in the pocket or receptacle should become so packed that it will not flow, a lever may be applied to the upper end of shaker rod, (shown in Fig. 4,) and by moving said rod back and forth it has a tendency to disturb the ore and dislodge same, so as to facilitate the How of same.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, i s
1. In a mechanism for regulating the flow of ore or materials in transporting same from one receptacle to another, the combination of two rods extending from the top of a pocket down to the lower end of the same and there secured, suitable trap-doors being secured on said rods, said doors being provided with suitable pegs or projections, suitable cog-wheels being secured on the upper end of said rods, said cog-wheels intermeshin g with each other, a suitable lever beingsecured on one of said rods, a suitable stopper to engage said lever, a smaller cog-wheel intermeshing with one of the main cog-wheels secured on the rods, said smaller cog-wheel being actuated by a lever, substantially as described and shown.
2. In a mechanism for the regulating the flow of ore or materials from a pocket or other receptacle, the combination of rods provided in or about the sides of a pocket, extending from the top to the bottom of same, doors being secured on thelower end of said rods and suitable cog-wheels being provided at the upper end of said rods, said cog-wheels intermeshing each other, a smaller cog-wheel intermeshing one of said large cog-wheels, both of said cog-wheels being operated by a lever, which lever engaging a suitable stopper, a
- suitable shaking-bar provided with a series of projecting pegs preferably placed at right angles, substantially as described and shown.
In testimony whereof we aflix our signatures in presence of two witnesses.
