To all whom it may concern:
Be it known that 1, GILBERT HENRY DAVID- SON, a citizen of the United States, and a resident of Morenci, in the county of Graham and Territory of Arizona, have invented a new and Improved Elevator, of which the following is a full, clear, and eXact description.
This invention relates to improvements in elevators, and is particularly useful in washing, separating and raising ore concentrates and the like.
An object of the invention is to provide a simple, strong and efficient elevator for raising ore concentrates and the like from washing tanks or separators, and discharging the same at a point remote from the container.
A further object of the invention is to provide a device of the class described, having carriers for raising material from a tank or container, and means for guiding the carriers so that they are inverted and discharged at a point in line with the direction of travel of the carrier.
A still further object of the invention is to provide a device of the class described, serving to elevate the material from a tank or container, and having means for advancing the material of greater specific gravity toward the elevator carriers and permitting the material of lower specific gravity to escape from the container.
The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of refer ence indicate corresponding parts in all the views, and in which Figure 1 is a longitudinal section of the elevator on the line 11 of Fig. 2; Fig. 2 is a transverse section on the line 22 of Fig. 1; Fig. 3 is an end elevation of the device show ing a part broken away; and Fig. 4 is an enlarged longitudinal section of a detail.
Before proceeding to a more detailed eX- planation of my invention, it should be clearly understood that the same is designed particularly for elevating" or raising granular material such as ore concentrates and the like, from tanks, containers or separators. However, the underlying principle of the I carrier arrangement of the elevator can be used in connection with elevators designed for other purposes, for instance, those used in simply advancing material from onepoint to another. 'My invention when used in ore concentration and similar operations facilitates the separation of the material of greater and of less specific gravity, as will appear more clearly hereinafter. The device is also particularly useful in connection with tanks for washing granular material and for removing the material from the liquid with n said tanks. I prefer to employ a special form of tank or container as is shown in. the drawings, though the construction of the same can be varied if so desired, to suit individual preference or special conditions.
Referring more particularly to the draw ings, I provide a tank or container 1 which may be fashioned from any suitable material and has the side 2 near the inlet end inclined. If so desired, a chute or inclined guideway 3 can be used for directing the material into the container. At the opposite side, the container has an overflow 4. permitting the escape of the liquid 5 within the container.
An inclined frame 6 having sides 7 and cross-members 8, has the lower end arranged in the container 1 adjacent to the inlet end of the same, as is shown most clearly in Fig. 1. The sides 7 of the frame carry bearing brackets 9, 10 and 11. The corresponding pairs of brackets are alined and have shafts 12, 13 and 14., respectively, journaled therein. The arrangement is such are near the upper and lower ends respectively, of the frames, while the shaft 13 is arranged between the end shafts. The respective shafts carry drums 15, 16 and 17.
An endless flexible band 18, fashioned from suitable belt material is arranged upon the drums 12, 13 and 14, and has the opposite runs 18 and 18 crossed between the drums 12 and 13. Adjacent to the crossing of the belt runs the frame 6 has a transverse in'ember 19, and at the opposite side supports 20, carrying a similar transverse member 21. A shaft 22 is mounted upon the members 19 and 21 and extends between the belt runs, having a roller 23 tapered toward the ends and serving to separate the belt runs and prevent their engagement. The band 18 has carriers 24., presenting laterally disthat the shafts 12 and 14 I posed flanges 25,- secured by rivets or screws 26 to the band. It will be understood that the carriers may be of any suitable form and may be mounted upon the band in any preferred or common manner. The carriers are preferably arranged so that they are sub stantially parallel to the horizontal plane when'traveling in the normal direction of the band or belt runs.
I provide a discharge hopper 27, adjacent to the drum 15 and arranged to receive the material elevated by the carriers. The arrangement is such that the run 18 of the belt has upwardly moving carriers. The crossing of the belt runs causes the carriers to deviate from the normal direction of movement, and to be inverted in passing over the drum 15 before they reach a point permitting them to discharge the material carried, into the discharge hopper 27. This arrangement permits the placing of the discharge hopper in a most advantageous location. Ordinarily, when the carrier belt runs are not crossed, the discharge hopper must necessarily be placed at the upper side of the inclined band. Owing to the inclined position of the frame carrying the traveling belt, it is difiicult to place the discharge hopper close to the run of the belt without interfering with the operation of the same. My arrangement, however, permits the discharge hopper to be located directly under the inverted and discharging carriers as is shown most clearly in Fig. 1.
A shaft 28, journaled in suitable bearings 29, located at opposite sides of the container 1, has a reel 30. The shaft 28 has a pulley31, connected by means of a belt 32 with a driving pulley 33. The latter is mounted upon a shaft 34, journaled upon bearing supports 35 secured to the sides of the container 1 and the sides 7 of the frame 6. The shaft 34 has a driving drum 36 engaging the under side of the belt run 18 and driven thereby, and in turn actuating the reel 30 through the belt 32 and the pulleys 31 and 33. As the reel arms rotate they pass into the container and advance the materiaLtoward the carriers. The heavier material, which settles near the bottom of the container, is pushed by the reel arms toward the carriers, while the lighter material nearer the top of the container is not acted upon by the reel and passes with the liquid over the overflow 4 and thus escapes from the container. The material is introduced into the container at the inlet end 2 and slides down the inclined side to a position where the major part of it is seized by the carriers and elevated to the discharge hopper 27. The moisture in the material on the carriers drains 0H as the latter advances toward the discharge hopper and thus the material reaches the latter with little adhering moisture.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent I 1. In a device of the class described, a traveling carrier for elevating material from a container, and means for guiding said carrier whereby the same is inverted to discharge at a point in line with the direction of its travel.

In a device of the class described, ,carriers mounted to travel, and serving successively to elevate the material from a container, and means for guiding said carriers whereby said carriers deviate from the normal direction of their travel and are inverted to discharge at the same side as the normal direction of their travel.

A device of the class described, comprising a container, carriers mounted to travel and to elevate material from said container, and means for guiding said carriers, whereby said carriers deviate from the normal direction of travel and are inverted, said carriers being further guided to discharge at a point in line with the normal direction'of their travel.
