` suchy agitation as will accomplish the results to produce agitation ofthe liquid contents of the tank. l

It is an object of my inventionto promote souoht in an aaparatus si'mnleof construction, inexpensive to manufacture, anc. sanitary in its e'ect upon processedl food prod# ucts. lt is a further object of my invention to promote the aforesaid objectsin a device from which the peripheral flow, of liquid .from the tips of"the .propeller blades is avoided, as I find that in case of some liquids sought to be processed l 4@get a superior result when liquidis'propelled from the pro-J` c. peller in a stream `at a moderate rate of" i l l particular embodiment, l wish it to be un-k speed. Other objects of my invention and the invention itself will be better understood by reference to the drawings accompanyingthis specification, and in which drawings,

Figure l shows an embodiment of my in vention shown mostly in cross section.

Figure 2 shows a plan view ofthe tank mechanism of Figure l, the view of Figure 1 being taken on a line l-I of Figure 2.

Referring to the drawings, at fig-A. are shown curved side walls of atank herein illustrated as cylindrical, and at B, is shown the bottom wall thereof., herein kshown as downwardly curved. Near the bottom wall of the tank, l perforate theside wally at a point C to admit a propeller shaft l) having on the end insidek the vtank a propeller E. Mounted on the opposite end of the shaft,

outside the tank, is provided a pulley l), by`

the propeller through the said space, de-

pendingon the direction of rotation of the said propeller.

Around the said propeller and preferably carried on the tipsvof the blades thereof, is mounted a metallic cylinder F, for a pur- .pose later to be made apparent.

' Whenthe propeller is rotated, the liquid f contents of' thetank are closed to traifel through the cylinder Fl and againstfthe opposite side wall of the tank, being deflected ythereby in all directions. n y n The tendency of the liquid contents of the tank torotate as Va whole is very much restricted by the. presence'of the cylinder F, which also restricts tbetendency'of the propellerjtov throwv olf particles of the liquid peripherally. ln this way greater flow of current is had traveling parallel with the axisofrotation kof the propeller shaft, said flow being of'considr-irable strength, though. f

of moderate velocity ascoinpared ywith the f peripherally flung currents, which other- .wise might be had in other constructions; alsothe tendencyof thepropeller to set up a rotary motion of the tank contents,ab`out an axis constitutingan extension of the propeller shaft, is notso great. l

Having thus described my invention in a derstood that l` do not limit my invention to it,'but am aware that numerous and eX- -tensive departures may bev made from the lembodiment herein illustrated and described and without departing from invention.
