SPECIFICATION forming part of Letters Patent No. 34,553, dated October 10,1899. Application sea Data; 27, 1898. 8.51.1 na'vooAsv. (No model.)

nia, have invented certain'new and useful Improvements in Mechanism forChurning and Aerating Liquids; and I do hereby declare the following to be a full, clear, and enact description of the invention, such as will enable others skilled in the art to Whichit appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to improvements in mechanism for churning and aerating liquids; and it consists, substantially, in the construction of an agitator on the lower end of a hollow vertical shaft, driven by suitable gearing, the wings of the agitator being made of inner and outer shells joined at their front edges, so as to leave chambers therein opening backward, the lower ends of which chamberscommunicate through like chambered radial arms communicating with the opening in the lower end of the hollowshaft. The wings of the' agitator are also so inclined that the rotation of the" agitator operates to throw away the fluid radially and'upward from the central portion of the bottom of the receptacle in which it operates, sons .to produce a partial vacuum at that point into which air passes down through the hollow vertical shaft and out through the chambers in the radial arms and wings of the agitator, so as to be distributed through the fluid in which the agitator is operated, thereby thoroughly aerating it.

In the drawings, Figure l .is an end view in elevation of my machine. Fig. 2 is a side View of the same, partly in elevation and partly in section. Fig. 3 isa top view of the fluid-receptacle of my machine, showing the removable deflectors in place therein. Fig. 4: is a side View of the agitator removed from the shaft. Fig. 5 is a view of the lower end of the agitator looking upward. Fig. 6 is a plan view of the upper end of the hollow shaft, showing the screened cap thereof. Fig. 7 is a sectional view of the upper end of the hollow shaft and the screened cap thereon.

In the drawings thus illustrating my invention, A is the base, which is provided with feet a a at itsfront end and is secured at its rearend in an upright frame B, provided with feet 17. In this upright frame B there is a gearwheel O mounted, the bearing 0 thereof being adjustable up and down in a slot b in the upright B, so as to admit of the use of different-sized gearwheels 0. This gearwheel 0 is also provided with a removable handle 0 for turning it by hand, and it is also provided with apulley C on the hub thereof, so that it can be operated by means of a belt, if desired.

From the front side of the upright B two arms D D extend forward over the base'A and are joined near their outer ends by a transverse piece D and in bearings d d in the upper end of the uprightB and the crosspiece D there is'mounted a shaft E, having a spur-gear e on its rear end intermeshing with the gear-wheel'G and on its front end a,

bevel-gear c. In the outer ends of the arms D D there are bearings 61 62 in which a vertical hollow shaft F is mounted and rotates, and: on Ithel shaft-F there is a bevel-gear f, which'inte'rmesh'es with the bevel-gear e on the shaftE; On this bevel-gear f there is a sleeve f, the lower end of which rests upon the top of the bearingd and in this sleeve there is a set-screw f by means whereof the bevel-gear f and its collar f can be secured to the shaft F, the shaft F being thereby adapted to be adjusted up and down and secured at any heightdesired. Upon the: top of the shaft Fthere is a removable screened cap f to prevent dirt from passing down through the hollow shaft F. Upon the lower end of the shaft F there is removably secured an agitator constructed of a vertical hollow tube G, open at the lower end and adapted to telescope over the shaft F and be secured in place thereon by means of a transverse pin 9 passing through holes in the sleeve and shaft. To this tube G there are secured,

preferably, three wings H, secured at their upper ends equidistant from each other to the tube G and at their lowerends to radial arms I, extending outward from the lower end of the tube G. The wings II, I make of .of the arrows in Fig. 3.

two plates h and h, joined at their front edges and open at the rear, so as to form chambers 7L2 therein, extending from the top to the bottom thereof. The radial arms I are also constructed in like manner of upper plates 1' and lower plates 1'', being joined at their front edges and open at the rear, the inner ends of the lower. plates c" extending partially under the open end of the tube G, so as to form chambers or passages extending from the opening in the lower end of the tube G to and into the lower ends of the chambers 71, in the Wings 11, so that air passing down the hollow shaft F and tube G during the rotation of the agitator passes out through the chambered arms I and up into the chambers 71 in the wings H and is dis tributed from the rears of said chambers into the fluid being agitated thereby. The outer ends of the radial arms I and the lower ends of the wings H are joined by braces J, adapted to hold them firmly against the strain exerted thereon when the agitator is being rapidly rotated in fluid.

The receptacle within which the agitator operates is an ordinary circular vessel K, which stands upon the base A, concentric with the shaft F, and is adapted to be removed when the shaft and agitator are raised. It is also provided with a removable cover L, divided into halves and recessed to fit around the shaft F. In the receptacle K are placed two or more curved deflectors M, provided at their upper ends, on their inner edges, with arms m, adapted to extend to and hook over the upper edges of the top of the receptacle K, and the outer edges of the upper ends of the deflectors are also provided with hooks m, adapted to hook over the edge of the top of the receptacle, while at the bottoms of the deflectors there are secured triangular braces m adapted to engage the inner surface of the receptacle and prevent the backward movement thereof, so that the braces on and m and the hooks m hold the deflectors M in place. These deflectors M are cut away at their inner lower corners to allow room for the operation of the agitator, and are also perforated with holes m through which a portion of the fluid in the receptacle passes when the agitator is being revolved in the direction For emptying the receptacle K a nipple is provided near the bottom thereof, on which a hose 7c is placed, the outer end of which can be raised, asillustrated in Figs. 1 and 2, to prevent the fluid from escaping from the receptacle K.

In operation the fluid to be aerated is placed in the receptacle K and the deflectors M placed therein.' The shaft F and the deflectors are then lowered into the fluid until the bottom of the deflector is adjacent to the bottom of the receptacle K. The cover L being then put into place, the agitator is rapidly revolved in the direction shown by the arrows in Fig. 3 by means of the gear-wheel O. This operates to produce a partial vacuum under and within the wings of the agitator, which operates to draw a strong current of air down through the hollow shaft F and the tube G, the greater portion of which passes out into the chambers in the radial arms I and a portion thereof up into the chambers in the wings H, and is thereby distributed through the fluid, which is also driven against the curved deflectors M, a portion thereof passing through the holes on therein and the balance passing the inner lower corners of the deflectors M and by this means becomes thoroughly intermixed and aerated.

It will be observed from the foregoing description that all of the parts of the machine coming into contact with the fluid can be speedily removed and cleaned without seriously disturbing the mechanism of the machine.

Having thus described myinvention, so as to enable others to construct and operate the same, what I claim as new, and desire to se cure by Letters Patent of the United States, is

The combination, with a vessel for holding liquid; of an agitator comprising a tubular shaft, radial arms I V-shaped in cross-section and secured to and projecting under the lower end of the said shaft, and spirally-arranged wings I-I V-shaped in cross-section and having their ends secured to the said shaft and to the free end portions of the said arms, the grooves in the said wings and arms forming air-passages and being in communication with the said tubular shaft; and means for rotating the said agitator in the said vessel, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK V. FOULKE.
