To all whom it may concern:

Be it known that I, CHARLES ALLEN, a citizen of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented new and useful Improvements in Classifiers and Separators, of which the following is a specification.

This invention relates to devices used in mining for separating solids and liquids in the treatment of pulp and slime's; and has for its object to render the discharge orifice of the settling or separating tank adjustable and to make all parts which are subject to wear easy of removal and replacement.

In devices of this type an inverted coneshaped tank or a tank that is a combination of cone and cylinder is employed, the apex of which carries a spigot for the discharge of the settling solids, the liquid and suspended particles overflowing the top of the tank. Pulp is fed in a continuous stream to the tank. It is desirable to vary the size of the opening of the spigot for different conditions of operation in order that the discharge of solids may be in proper proportion to the rate of settlement. This I accomplish by providing a swinging plate carrying two 'spigots of different size m0vable into place beneath the apex of the cone and both removable from a socket in the plate, whereby other and different sized spigots may be substituted and worn ones replaced. Also in devices of this kind as heretofore constructed. the valve either seats interiorly of the cone on the upper face of the spigot or if on the lower face it is so fixed that it cannot be conveniently replaced, or without interruption of the normal operation of the cone, and since the wear in a device of this kind occurs almost wholly on the valve and spigot the device rendered useless during the replacement of the worn parts. By making the spigots removable and arranging the valve beneath to seat on the lower face exteriorly of the cone, I can employ removable valves and spigots and also make the area of discharge opening, adjustable by hand to compensate for wear, without interrupting the operation of the cone.

In the accompanying drawings:

Figure 1 shows a vertical, sectional view of the lower portion of the tank fitted with a swinging plate carrying a plurality of removable spigots. i

Fig. 2 shows an inverted plan view of the same.

Fig. 3 shows a view, similar to Fig. 1, with a ball valve carried removably on a lever arm and seating against the lower, outer end of the spigot.

Fig. l shows a vertical, sectional view of a complete device, including the removable and adjustable spigots, a ball valve capable of removal and adjustment, and automatic mechanism for controlling the position of the valve.

A cone-shaped tank 10, of any suitable form such as is used in classifiers, slime separators, slime thickeners and the like, has its apex provided with a cone-shaped. casing 11, the lower end of which carries a flange 12. Pivoted upon the flange, by

means of a bolt 13, is a plate 14 in the shape of a sector, which plate has two sockets shouldered at 15 to receive each a spigot 16, the latter being provided with a flange 17 resting upon the shouldered portion of the socket. These two spigots have discharge orifices 18, each of a dilferent size, and either may be moved to position beneath the open end of the cone in register therewith. The sector has the opposite ends of its arcuate portion provided with hooks 19 to cooperate with a clamping bolt 20 carried by the flange 12, diametrically opposite to the bolt 13 and when one of the spigot-s is in operative position beneath the open end of the cone, the adjacent hookshaped member is engaged by the clamping bolt 20, whereby the plate is retained in position.

By reason of the shouldered socket in the plate 14 to receive the flanged spigot, said spigots are easily removable when the plate is swung from beneath the flange 12 of the casing 11. Therefore, new spigots may be substituted for worn ones or other spigots with different sized orifices 17 may be made use of, whereby to vary the volume of discharge from the cone. Also the spigots may beremoved and the full size of the opening in the cone taken advantage of for discharging the material therefrom.

While it is within the purview of my invention to employ the removable and replaceable spigots without valve mechanism of any kind, merely making use of the different sized spigots in the same plate to regulate the discharge, I may, and preferably do, employ in association therewith a valve of a type to be easily replaced and so arranged as to offer no obstruction to the swinging movement of the plate 14:.

As shown in Figs. 3 and 4:, this valve may comprise a ball 21, preferably of rubber or other elastic material, supported by a pin- I tle 22 removably carried on the intermediate portion of a lever arm 23, the latter tulcrumed at one end on a bracket 24c formed upon the-casing 11 and havin its opposite end arranged to receive suitable operating connections. The ball valve 21 is rotatable upon its pintles to expose new surfaces for wear against the spigot 16 and is readily removable for replacement or to permit non-interference with the discharge from the spigot, the lever arm at this point being made in two bowed parts 25.

, As shown in Fig. i the ball valve 21 may be seated in a socket 26 formed upon the lever arm, said socket being provided with an opening to permit the pulp and slime to pass through when the ball is removed. in this form the ball. may be'turned in any direction to present new surfaces to wear. Also in this form I have shown the lever arm .23 connected to and operated by automatic mechanism 27, similar to that shown and described in my Patent No. 1,1 17 ,356, issued July 20, 1915. Obviously a disk may be substituted for a ball,-such disk being made removable and its position changed without interfering with the operation of the cone or swinging plate, and other changes in the construction and arrangement of the several parts herein shown and described may be employed without departing fromthe spirit of my invention as disclosed in the appended claims.

The purpose of varying the size of the spigot is to proportion the volume or" discharge of solids in accordance with their rate of settlement, as otherwise a condition will exist where if the pulp be unusually thin and the rate of settlement of solids consequently slow, the volume of discharge will be too great and result in carrying off liquid and suspended particles at the bottom in stead .of the top of the tank, and, on the other hand, if the pulp be thicker than usual the normal size spigot will clog-up or fail to discharge with sufficient rapidity.

Having thus described my invention, what I claim anddesire toisecure by Letters Patent is- 1. A separating and classifying device for pulp comprising a settling tank having a discharge orifice at its bottom, means for supplying a continuous stream of pulp to the tank, the solid particles settling to the bottom of the tank and escaping through the orifice therein and the liquid and suspended particles overflowing the top of the tank, and means for varying the size of the discharge orifice for proportioning the discharge of solids in accordance with their rate of settlement, said means comprising a holdercarriedby-the tank, and a plurality of spigots of varying sizes removably car 'riedby the'holder and movable each into position beneath the discharge orifice.
