IMPROVEMENT IN ORE-SBPARATORS.

The Schedule referred to in these Letters Patent and making pat; at the same.

I, HOSEA Biinl ot the city, county and State of New ii'ork, have invented an improved Ore-Separator, of which the following is a specification.

Nature and Objects of the Invention.

M y apparatus is designed to sort into various (llllll ities, according to gravity, metallic ores reduced into 11 wml imli fi l li ll- 'lhc slimes from the stamps, for instance, are discharged in regulated quantities into an ascending body of water, which carries the relatively lighter portions to one point of.disehargc, and allows the heavier to sink iutoanothcr receptacle.

The special .poiuts of invention which distinguish my apparatus from those which have preceded it are:

First, the distribution o comminnted ores, of varying degrees of fineness, to separate trunks, in each of which the rate of motion of the column of water is adjusted to the specific requirements of the grade of ore in said trunk.

Second, the emission of the commiuutod ore through an annular throat at the end of the feed-pipe, atwhich point; it meets the upward current of water, which thence flows in an annulo-oylindrical trunk within an outer casing, or dowucast trunk of similar character.

Third, the coaxial arrangement of the downcast water-trunk, npcast water-trunk, and central feed-cylinder, giving a compact form, and one not subject to induce irregular currents, or such as may have uncqual force at ditierent parts of their course.

General Description.

The upper port-ion of the apparatus, which distributes the ore or slimes into the trunks, is exhibited in figs. 1 and 2, and to those views the first part of the description will partichlarly refer.

A is a sponsor pipe, which conducts the slimes from the stamping-mills or grinder, and delivers them into The the smaller end of the perforated cylinder B. perforations at the imluction-eull are liner, or the meshes of the wire-cloth are smaller, as the case may he, than at any other point, becoming coarser toward the larger cud oi the cylinder. Difi'crcnt sections of the length oi the cylimlerhave ditlbreutgrades of linencss, so as to distribute to each trunk an :unn-oxhuately even quality of ore.

The cylinder has a rotary motion by means of a crank or band.

C is a water-pipe, with branches 6 t", which convey water from the tank 0 into the cylinder, and distribute it in sprays through numerous holes. The cutering shares are supposed to have water enough to convey the finer particles through the meshes or apertures near the entering end of the cylinder, and the pipe 0 is shown as destitute of holes for a. portion of its length.

Beyond this closed portion the pipe is perforated, as is also the companion pipe 0 which enters from. the other end of the. cylinder, the object being to atiord a .sullicient amount of water to encourage the passage of the various grades of Slimes or comminuted ores through the meshes of varying openness, as they are successive] y traversed.

.lfig. 1 shows four trunks in position to catch theresults of the sifting arrangement described, but I do not limitmysclf to any particularnumber.

The shaft b passes through the cylinder B, and is supported in such a way as not to interfere with the passage of the pipes which convey the water.

The slimcs which pass from the sifting or gradingcyliudcr B are received in the successive hoppers 1) l) l)" D", which convey the graded qualities to the respective trunks E E E" 19", in each of which the said ore is subjected to the action of water, to sort it according to gravity into two parcels. It. will be apparent from the description that the truukE will have the finest quality and 15" the coarsest, the tbrmer being perhaps an almost impalpahle powder, and the latter having particles perhaps as large as cubes of one-eighth inch on their sides.

The ore and water falls into the central cylinder F of the washer, and is thence distributed into the upcast water-trunk G, passing against the periphery of the cone or valve H, which regulates the feed, and which is adjustable vertically by the nuts h h, so as to vary the width of the annular opening according to the size of the particles of ore, and the other possible requirements of the process, such as those resulting from comparative poverty or levity of the gang, &c.

Each trunk is' supplied with water by means of a pipe, K, from the tank 0'. The water is received in the funnel l. belonging to the tank, (see figs and 1,

es ll strikes'against the are as it issues from the annular opening bounded by the cone H and the lower edge of the cylinder 1".

The cfl'cct ot the upward column of water is to car ry up all the particles which have less than a certain speeitic gravity, or which present a certain amount; of surface to the current, while those of a heavier description will sink to the bottom of the tank J. The said lighter particles tiow out at the spouts L, and are treated according to their character. The heavier particles are removed, as occasion may require, from the man-hole or shovel-hole M.

The description just given applies in general terms to each of the trunks, the operation proceeding simultaneously in each, but a variation occurs in the area of opening around the valve H, and, also, in. the amount oi'watcr ali'orded to each trunk, according to the grade of the me under treatment.

The valve H may be of other forms than that represented, the annular character of the throat or feedopening being maintained. I do not desire to confine myself to any particular form of valve.

The tank 0 has an overflow-pipe, and the water in the tank is thereby k pt at a constant height, so that its regulation may remain uniform, when once adjusted.

The co-avial fll'i'nligel'nenii of the cylinders J G F,

ducts, and the ore-supply pipc, serveto distribute the water to the ore in an equable manner, reasonably free from counter-currents and special determination of the water to particular points. Were the water introduced at one or several points it would produce edthe ore, and would thus fail to exert a uniform action thereupon over the whole sectional area, at which takes place the critical selection by gravity, determinin, the destination of the individual particles.

What I claim as new is-- 1. The cylinder 13, having meshes or perfiirations of varying fineness at different parts of its length, and acting in connection with the necessary ore-c r spout and water-pipcsto distribute the graded ore to different trunks, substantially as described.

2. The combination of the adjustable valve H with the co-axial cylinder J G F, operating, as described, to emit an annular stream of ore against an ascending: current of water, for the purpose stated in the specification.

3. The co-axial' arrangement of the cylinders J G I", constructed and operating as dcscrihet To the above specification of my improvements in ore-separators]. have signed my hand this 7th day oi May, A. 1). i870.
