To all whom it may concern: 7
Be it known that I, OWEN I-IAWKINs, a citizen of the United States, residing at Globe, in thecounty'of Gila' and State of Arizona, have invented a new and Improved Ore-Separator, of which the following is'a full, clear, and exact description.
This invention generallyrela-tes to a new and improved means for separating or classifyingmaterial according to various sizes.
In the present application it is more par ticularly for use in the milling and concentrating of mineral ores. Ithas for one of its objects the provision of a means whereby the materials may be more readily and thorough'ly separated. 7
Another object is to provide an improved method for use'in that class of separators in which the crushed or ground ore is fed to a screen mem'berwith water or other liquid, the undersized material'and liquid pass ng through said screen and the over-sizedmaterial being retained and collected above said screen. Heretofore there has been a tendency for the screens to become'blinded or clogged, thus permitting a considerable portion of the under-sized material to be carried away with th'eover-sized material and so preventing a proper separation.
Another object of this invention is to overcome the above objection and provide a means which precludes the possibility of the screen becomingblinded or clogged, thus affording a means whereby practically all of the undersized material will be separated from the over-sized material.
By under-size is meant that material which will pass through the openings-of the screen, and over-size, that which is too large to pass therethrough.
In. order to accomplish the above-named objects there is provided an inclined screen member reciprocating longitudinally, and a member located below and cooperating with said screen, so arranged that a series of impinging currents of water strikes the lower side of the screen. In the structure shown there is provided a series of steps arranged beneath the screen, with the intersection of the tread and riser portion spaced from the tread a sufficient distance to permit the downward flow of the water thereover to carry with it the under-sized ore which has passed through the screen. As the water passes over these points of intersection, there is formed a wave or crest of Water Specification of Letters latent. Patentd Aug. 5, 1919. Application filed March 12, 1919. Serial no. 282,098;
whichimp'inges against the lower side of the screening member, part of which water passes therethrough and tends-to, loosen por tions of material which have become clogged in the openings,l1and carries any remaining J A S AT N OF m portionsofunder-sized material through the?" 1 screen'as the water again: passes downward from the screen to the next successive step.
This process is repeated throughout; the length -of the inclined surface. I
part of this specificatiomsimilarcharacters of reference refer to correspondingpartsiin the several views, in whi-ch,-
Figure 1 is a longitudinal sectional view In the" accompanying "drawings, forming showing the relative arrangement ofthe.
feeding hopper, sc reening member, "the means for'obtaining the series of impinging. currents to same, and the actuating means for. effecting the reciprocating longi tudinalmovement therebetween; V
Fig. 2 is a sectional view taken on the line 22 of Fig. l with supports removed; and
.:Fig. 3 is a plan view looking down at'th'e' upper part of the separator.
In the accompanying drawing-the preferred form of my invent on is shown as comprising an inner framemember having sides 1 and a screening member 2, connecting the bottom thereof, said inner frame member having bearing blocks 3 suitably secured to the side members thereof, and adapted to slide on guides 4, which are in turn mounted upon-the side portions 5 of an outer launder.
The said side portions 5 are suitably connected by a connectingmember 6. Thelaunder is supported in an inclined position by a frame structure comprising supports 7 and the connecting member 8. Any suitable means is provided for securing the reciprocating longitudinal motion of the inner frame member relative to the outer launder. To effect this movement there is provided a driving member 9 mounted on a crank shaft 10 in'bearing blocks 11, which are suitably secured to the stationary side portions 5 of the outer launder. Reciprocating motion is imparted to the inner frame member by means of connecting rod 12 having one end j ournaled in a bearing 13 which is suitably connected to the inner frame member and the other end with V V the crank shaft 10.
In the bottom of the outer launder there is 7 the surface of the tread portion being inclined in such position as to carry the water or other material down the launder. The upper part of the riser is spaced from the. lower side of the screen a sufficient distance to permit a certain portion of the water to 7 material which have become clogged in the screen member, thus keeping the screen open at all times. This process of having the water pass through the screen is repeated a number of times throughout the length of the launder. This, in connection with the longitudinal reciprocating motion .of the screen member brings all parts of said screen member under the cleaning efi'ec't of these series of waves or falls which are formed by the water flowing over the series of steps. After the water has passed through the screen from the bottom it will alsohave a tendency to carry with it any remaining under sized material. Itis thus seen that by providing a launder ofsufiicient length that all of the under-sized material may be carried through the screen and collected at a suitable point 17, The motion of the'inner frame member further tends to carry the over-sized material to the bottom of the launder where it: may be deposited on receiving members 18. s I In operation the crushed or ground material carried in the wash water is fed to the screen member through a hopper 19.
What I claim is:
1. In. an apparatus of the class described, an inclined frame member, a screen therefor, a series of stepped portions arranged below said screen to cause a plurality of independent currents of water'to strike the bottom of said screen member and a means for obtaining relative movement between the screen member and the stepped member.
2. In an apparatus of the class described, an inclined screen member, a series of stepped portions beneath and adjacent to said screen member and means for obtaining a reciprocating movement between the screen member and the stepped portions.
3. In an apparatus of the class described for separating material carried in a wash water, an inclined movable screen member and relatively fixed meansspaced'below and adjacent to said screen member to cause water flowing thereoverto strike the bottom of said screen member;
4. In an apparatus of the class described, a stationary inclined launder, stepped portions therefor, a movable screen member spaced above andadjacent to said steps and a means for obtaining a reciprocating motion of the screen member with respect tothe stepped portions.- 7
5. In a separating. device for straining crushed ore carried in a liquid, an inclined frame member, a screen therefor, steps spaced from and positioned below said frame'member, said stepshaving the edges thereof separated from the screen a sufficient distance to form as the liquid flows thereover a series of impinging waves or crests which strike the said screen and a means for obtaining relative motion between the said steps and said screen. i
6. In a separating device for screening crushed ore carried in a liquid, a frame member, a screen therefor, a trough, steps therefor having the edges thereof separated from the screen a sufficient. distance to form as the liquid flows thereover a series of impinging waves or crests which strike the screen and means for obtaining relative motion between the steps and the screen member.
