MAGNETIG onE-sEPAnATon.
.To aZZ. whom t may concern:
Be it known` that I, HENRY H. WAIT, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and -useful Im rovement in Magnetic Ore-Separatore, of which the following is a full, clear, concise, and exact description. My invention relates to a magneticv oreseparator; and its object is to provide an improved simple machine which will be especially efficient for the concentration of ores or mixtures of materials in the presence of water and in Which materials 'of different specific gravities, some of whichy are magnetic, may be Separated by a single o eration. Briefly, my invention contemp ates the provision of means whereby the separating action of a powerful magnet is augmented by vibratory motion in a fluid medium which carries the material in proximity to the I will describe my invention inl detail by reference to the accomy anying drawings, which illustrate the pre 'erred embodiment thereof, and the arts, improvements, or combinations whicllfI regard as novel will be pointed outv inthe appended claims.
In the drawings, Figure 1 is a vertical sectional elevation of the machine. Fig. 2 isa flsiansverse vertical section on plane 2 2 of lg. 1; modified'form of armature-cylinder for the se arators. i
he same letters of reference indicate the same parts wherever shown.
In general the princi le ofv this machine is to pass the material to e treated through a fluid medium, such as water, to which fluid a vibratory motion is imparted by any suitable means, and to associate a powerful magnet (preferably moving) withthe apparatus in such a way as to attract the more permeable particles'of the mixture, the vibratory motion in the fluid serving to bring the material being treated into intimate relation to the magnet to loosen or assist inthe segregation of the material, so that the influence of the magnet upon the permeable particles in the mixture will be rendered more effective, and
also to reduce a further separation of the gravities. f

Fig. 3 is a detail view illustrating a 2 Patented April 23, ).907. A
As shown in the drawings, a magnetic separating-cylinder a is arranged torotate on a horizontal axis between the poles N and S of a suitable field-magnet, said poles being placed refspectively above and below the cylmder, an said cylinder is arranged to rotate in a trough containing Water or other suitable fluid medium. A
An inclined screen or support b is provided immediately below the surface of the cylinder, the space between the cylinder and screen forming the working passage through which the material being treated is caused to progress. A chute E is shown, through which the material is fed into the working passage. I
Between the magnetic cylinder and the pole-piece S there is of course an intense magnetic flux, `and this flux is preferably caused to converge toward the surface of vthe cylinder by means of permeable projections or teeth upon the vsurface of the latter, from which teeth the lines of force are dis- It is understood that in magnetic attraction the movement of the particle is along converging linesof force, and it will be seen that when the material passes through the dense field existin between the cylinder a and pole-piece S t ie more permeable particles will be drawn up toward the surface of the cylinder.
A reciprocating piston H in .one compartment of the trough is shown for giving a vertical vibratory or oscillating motion to the' l Water, and the screen or support b is finely perforated, so that this vibration in the' fluid Will be transferred to the materials in the working passage. The pole-piece S is also preferably perforated, as shown, to allow the vibratory motion to be communicated as directly as possible to the fluid at the place where separation takes place.
A suitable divider-plate c is mounted With its edge close to the surface of the cylinder near-the point Where the screen b turns down and .away from said cylinder-that is to say, where the material as it progresses along the passage leaves the region of the magnetic field. This divider is so placed that .the nonmagnetic material passes down on one side of it and leaves the machine at the spout e, while the magnetic material is carried over beyond the dividing edge and is finally released IOO on the other side and discharged through thel spout f. The -vibratory motion in the fluidposite the'mouth of the working passage in front of what maybe termed the magnetic v divider c. The agitation of the water in the a spout g. The magnetic particles Fig. 3 shows such a discharged at f,
working passagetends particles of non-magnetic 'fore rise toward the top, so that they will be carried on past the divider d to 'be discharged through spout e, while the heavier particles will not be carried on, but will drop dow/n in front of said plate d and may be discharged through to make the lighter carried on' until they have vpassed the farthest divider c,either because they have adhered to the surface of the cylinder, and so been positively carried over, or because their apparent or effective specific gravity has been so modified by the presence ofthe magnet that they are held suspendedl in the water so near the top of the stream of lore that'its natural fiow carries them over.
The location of the separating-cylinder between opposing magnet-polesl of opposite polarity, as shown, is advantageous, because the magnetic pull on the armature and also its weight may be approximately balanced, and also`because a neutral point is established upon the surface of the cylinder at a point between the poles at which the attracted material will be released.
The spaces between the teeth are preferably filled with wax or .other suitable non-magnetic meterial, so that the physical surface of the cylinder is comparatively smooth to avoid unduly churning the water in its rotation.
The cylinder may be grooved instead of being toothed-that is to say, the dispersions of the fiux can be from lines o r narrow areas continuing clear around the circumference. grooved construction with considerable spacm between the circumferential ridges to a low the -`Water to passto and fro more readily. ,i
The operation of the machine has already been indicated as an incident to the descripytion of its structure. The ore is fed into the chute E, and the armature A is caused to rotate in the.4 direction ofthe arrow. The piston His also caused to reciprocate, as by the eccentric mechanism shown. The result will- .be not only a very eicient magnetic separation of the permeable particles from the rest of the ore, but alsov a gravitational separation of the-heavier particles from those Which-are lighter, the magnetic product being vproduct at g.
will be said cylinder and magnet-pole an the lighter non-magnetie-- product at e', and the'heavier non-magnetic' I It will be evident to those skilled in the art that many ymodifications may be made in the machine \illustrated withoutl departing from the general ideas herein set forth.
