FRANK E. MARCY, OF SALT LAKE CITY, UTAH,` ASSIGNOR, BY MESNE ASSIGNMENTS,

TO ALLIS-CHALMERS MANUFACTURING- COMPANY, A CORPORATION OF DELA- WARE.

AGITATOR.

`Specification of Letters Patent.

. .Application filed February 2'77, 1909. Serial No. 480,359.

To all/whom t may concern.'

Be it known that I, FRANK E. Manor, a

l citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented avcertain new and useful Improvement in Agitators, of which the following is a specification.

This invention relates to improvements in the construction of agitators and in particular to such construction as` applied to agitating tanks for liquids such for instance as Pachuca tanks for the agitation of slimes.

Thel object of the invention is to provide a simple and efficient methodof main! taining a constant circulation of liquid within a tank by the application of mechanical means.

Aclear conception of the invention can be obtained by referring to the accompanying drawings in which like reference char-- acters designate like parts in different views.

Figure 1 is a central vertical section of an agitating tank constructed according to the invention. Fig. 2 is a plan view of same.

The tank 1 having the conical bottom 2 is held in a vertical position by the braces 9. A ipe 3 having the flange 7 upon its lower end) is held in a vertical position in the center of the tank 1 by means of radial braces.

4. A short pipe 8having its axis at right flange 7, so that an opening through the wall of the pipe 8 forms va connection between the interior of the pipe 8 and that of the pipe 3. The pipes 3, 8, are supported 'within the tank so that solution may freely enter at the ends of the horizontal pipe/'8 and they are readily detachable and removable from the tank. A horizontal shaft 6 supported by the bearings 5 in the bottom 2 of the tank 1 passes through the pipe 8 so that its axis coincides with that of the pipe 8. The shaft 6 supports a pulley 17 on the exterior of the tank 1 and the screw.,

pumps 10, 11, on the interior of the tank 1 and the pipe 8. These screw pumps 10, 11,

. are locatedin the inlets of the'pipe 8 and are right and left hand in, construction. The vmotor 16 is connected with the pulle 17 through the medium of the belt 18. The discharge opening 12 in the bottom 2 of the tank 1 is located in the center of the tank 1 directly above a gate valve 13. The elbow ted through the pipe 15.

14 leading from the gate valve 13 may lead to any desired source. The inlet 15 is attached to a supply of compressed air or liquid not shown.

In operation of the device the solution to be agitated'is admitted into the upper part of the tank. The -motor 16 is set in motion, causing the screw pumps 10, 11, to revolve and force the liquid up through the pipe 3. The solution may freely enter horizontal pipe 8 at its ends and the iniiowing solution serves to prevent packing of any solids that may be in suspension in the bottom portions of the tank.l As the, liquid rises in the pipe 3, it is iinally discharged from the top opening of said pipe 3 and iiows back toward the'bottom 2 of the tank 1. If there be solids in the solution and they should tend to clog the lower part of the tank 1,v

air or liquid under pressure can be admit- In discharging the contents of the tank 1, the gate valve 13 is 'opened and the material passes outA through the elbow 14.

It should be understood that it is not desired to be limited to the exact details of construction shown and described, for yobvious modifications will occur to a person skilled in the art.

It is claimed and desired to secure by Let-V ters Patent:

1. In an agitator, the combination of a tank, an upright pipe centrally therein and supported thereby, a lower pipe connected transversely to said upright pipe and having an endfreely opening into said tank whereby solution may enter freely at said end of said pi'pe, a single shaft extending into said lower pipe, pumping means on said shaftwithin said lower pipe, and driving means on said shaft without said tank.

2. In an agitator, the combination of a tank, an inverted T-pipe in said tank, said pipe being spaced from the tank, and means 'in the horizontal portion of said T -pipe for pumping the tank contents through the upright portion of said T- ipe.

In testimony whereo .I aiix my signature in the presence of two witnesses. F. E. MARCY. vWitnesses: A
