an improvement in i at different speeds at different points or areas throughout the mixture.

This invention includes a shaft, a cone, and

rings open at both ends and surrounding the shaitand discharging through an opening in the cone, and extending to or a short distance into each other and in the cone, and either the cone or rings or both may have baflies or fins 5 therein if desired to facilitate the action upon the liquid solution undergoing treatment therethrough.

In the accompanying drawing: Fig. 1 is a View showing a cone and shaft with two rings, the dotted lines. showing possible extensions of the rings; Fig. 2 is a View showing the same general arrangement horizontally disposed instead of vertically as in Fig. 1;

Fig. 3 is a view showing a slightly modified form in which the rings are fastened to the 1 walls of the tank; and

Fig. 4 is a plan View of the mixer shown in Fig, 1. i

The letter A, represents the usual tank; tie a rotary shaft; 2 is a cone;.and3 and 4 are cylindrical rings of different diameter, the smaller 3 of which extends to the opening in the upper. end of the larger ring Land the larger ring 4 extends to theopening in the smaller end of the conei2. The dotted lines in Fig. 1 indicate that the ends of the two rings may be extended somewhat, the smaller ring into the larger ring, and 45 the larger ring into the smaller opening of the cone.

Obviously, the number of rings might be varied as one alone might possibly serve very well, or there, might be more than two. i

These rings might be secured to the shaft I as is the cone 2, to rotate withthe shaft, or the rings might be supported from the tank and re main stationary.

In Fig. 2, the same elements are disposed horizontally instead of vertically, merely as an indi- 1938, Serial No. 186,718

cation that either, or in fact any other, position is contemplated.

In Fig. 1, full and dotted lines indicate baifies or fins 5, which might extend lengthwise axially of the cone alone, or of one or more of the rings, or of the cone and one or more of the rings. These, preferably, extend as illustrated, in the general direction of the Shaft.

In addition to the showing in the four figures of the drawing, the invention also contemplates an inverted position or a position just the reverse of that shown in Fig. 1.

The foregoing constructions have been tried out and have proven to have very special advantages over many known structures for mixing materials hitherto employed.

I claim:

1. A revolving cone mixer which includes a shaft and a plurality of rings, all concentric with one another, and each discharging into the other, at least one of the rings having a baffle or fin extending longitudinally thereof, and at least two cones of different pitch discharging toward each other, and having inlets at their smaller ends outside of and surrounding the rings, W

2. A revolvingcone mixer which includes a shaft and a plurality of rings, all concenctric with one anothenand each discharging into the other, one at least of the rings and cones having bafiies or fins extendinglongitudinallythereof, at least two cones on the shaft having unobstructed interiors discharging in a direction toward each other, and into which cones one of the rings discharges. i

3. A revolving cone mixer which includes at least two cones having free and open centers, each having inlets at their smallerends, the

cones of different pitch and'discharging at their larger ends toward each other, and one outside of the outer rim of the other, a shaft to which the cones are secured, and rings of different diameters concentric with the shaft and with one another and discharging through the ring next adjacent, and one ring discharging into the smaller end of a cone.

4. A revolving cone mixer including a cone, rings and a shaft for rotating the cone, onering discharging into the next adjacent ring and one into an end of the cone, the cone and at least one ring having inlets outside of the next adjacent ring as well as through the rings.

5. A revolving mixer including a shaft having two cones rotated thereby, said cones discharging at their larger ends toward each other and having inlets at their smaller ends, and a ring each other and having inlets at their smaller discharging into one cone and a second ring ends, and a ring discharging into one cone and discharging into the first-mentioned ring. a second ring discharging into the first-men- 6.
