To aZZ whom it may concern: I

Be it known that 1, JOHN W. PrIrLLrr-s, a citizen of the United States, residing at Sil- .ver City, in the county of Lyon, State of raters and more particularly to that class of separators which are utilized to separate ores from liquids.

The primary ob ect of the invention is to provide a separator which will efliciently same.

perform its function in completely separating the-ore and liquid introduced therein.

The invention includes among other features novel means for removing the liquid and ores from the machine during the proccss of separation.

The device is of such construction that. the mixture will not he directed against the walls of the separator until it has entirely entered the same, the means for so directing the liquid being a rotary disk which is located adjacent the middle of the device.

As a further novel feature, the-invention includes means for removing an separated ore which may collect in the bottom of the se arator.

- 11 tlie'accompanying drawings, Figure 1' is a view in elevation of the separator. Fig.

2 is a vertical sectional view through the Fig. 3 is a top plan view of the same.- Fig. 4 is a horizontal sectional view on the line -i-:i of Fig. 2. Fig. 5 is a vertical sectional View through the lower end of the casing of the separator, showing a slightly modified form of theinvcntion, and, Fig. 6 is a detail perspective view of the scraper.

Referring more specifically to the drawings, the numeral 10 denotes the upper portion of thc'frai'ne in which my separator is mounted. A shaft 11 has a hearing in the frame 10 and upon. the said shaft,-al ovc the l'ra n c, is secured a pulley 12 around which is engaged a bolt 13 from a drive shaft (not Shown) l):\' l1l0i1HS 0f which the shaft 11 is rotated. To prevent upward movement of the shaft 11 in its bearing in the frame 10,

a collar 13 is secured upon the shaft by means of a set screw 14. and bears a ainst,

the under side of the frame 10.

The separator includes a casing com--- posed of major and minor frusto-ccnical sections 15 and 16 respectively, each oi which is provided at its base with an annular flange 17 by means of which the ens are united. its upper end with an inwardl directed annular flange 18 .to the under side of which is secured .the upturned ends of arms 19 which radiate from a collar 20 secured to the shart 11;. in any suitable manner. These arms 19 support the casing as will be readily understood and cause rotation of the said casing with the shaft 11. Formed in the upper end of the minor section 16 at its junction with the flange 18 is anannular series of openings 21 which constitute an outlet for the liquid separated from the mixture introduced into the separator as will be hereinafter fully explained. Secured in any desired manner to the under side of the frame 10, is an annular trough 22 which.

has its inner. side lying close to the sideof the minor section 16 below the openings 21 and its outer side 23 extending with its upper edge above the plane occupied hythe series of openings. -Leading from the sin-- nular trough is a spout .Z with'which is connected a pipe 25 through which. the Waste liquid is discharged. in order that the waste liquid as it is discharged through the openings 21 may be directed into the trough 22, I provide an annular deflector plate 26 which is secured at its inner edge to the flange 18 and which has its'outer edge directed downwardly, as at 27, into the trough 22 and in the direction of the outer side 25 of the'same.

It will, oi course, be understood that the raw material to be separated is introduced into the separator from thetopand in order of therasing adjacent its upper end, an annular shield 28 is provided, the said shield edge of the annular iangc 18 and depends therefrom, and has its wall tapered upwardlyv annularly as at .27, to receive the upper end The seetionlG is provided at to prevent the same from reaching the sides of a sloeve-shaftglSi, which is disposed upon the shaft- 11 -arid has. its lower end resting 5 being secured at its 11 per end to the inner upon a collar 29 which is secured by means of a set screw 30 to the said shaft 11. Secured upon the sleeve-shaft 28 adjacent its lowerv I I upper and outer edges with upwardly directed extensions 33 to the outer edges of which.

and the said wings proper are secured s irally disposed blades 34 which contact with the inner face of the major section. The extended portions 33 terminate in a plane In above the junction ,of the two sections and the up er ends of the blades 34 are tapered to con orm to the taper of the wall of the minor section 16 to prevent lodging of ore in angle formed by the connection of the two 2 sections. Each of the wings 32 is provided with an opening 35 to allow free circulation of the liquid during the process of separation.- Secured to-the shaft 28 and the upper edges .of the wings 32 in a plane below that occupied bpthe lower edge of the shield, is a circular te 36 upon which the raw material, is thrown, by means of the said annular shield 28. From this plate the material is thrown by centrifugal force upon the sides of the casmg and is acted upon by the spirally arranged blades 34, which force the waste liquid upwardly and through the openings 21 and allow the heav particles of ore to descend. The taper of t e minor section 16 is such that 3 should any particles of ore be .carried by the I liquid against the inner face of this section, the said particles will by reason of their I gravity and the centrifugal force exerted, drain back to be acted upon by the blades 34. 4 In the'preferred form of my invention, the wings 32 and blades 34 terminate short of the lower end of the maj or section 15 and this said end 1s provided witn an inwardly directed an: nular ange 37 upon which the particles of ore are designed to lodge. Secured to the sleeve 28 is a scraper 38 which is formed of sheet metal and has its blade ortion bent longitudinally at right angles to orm a portion 39 which lies vertically with res and a portion 40 whichlies parallel to the said flange. I The portion 39 is notched as at 41, I to receive the flange 37 with the lug 42, formed by notchin the said plate, ying against the under si e of the flange 37 to pre- ,-vent vertical movement of the scraper. The

ortion of the blade located above the notch.

1s ada ted to scrape the surface of the flange 37 an the portion 38 of the scraper revents the ore from running over the said b ade portion 39. curved in'a direction opposite to the direction of rotation of the casing ,of the separator in order to direct the accumulated ore from the flange 37 into a suit-able receptacle (not shown) 1 I trough.

ect to the flange 37 The scraper has its outer end In the form shown in Fig. 5, the spiral blades extend to the extreme lower end of the major section 15 and deposit the sepa- I rated ore directly into a suitable receptacle, the flange 37 in this'case being omitted.

I In practice, the pulleys 12 and 31 are of such size that shaft 11 and sleeve shaft 28' will be rotated at different speeds, the shaft '28 more rapidly than the shaft 1 1.
