ssneets-sheet 5 Patented June 17, 1924. a fl unites stares NOAH. WALKER, or PHILADELPHIA, rnnNsYLvAnIAQ BEVERSIBLE AGITATING APPARATUS FOR rL-orns.

Application filed December 10, 1921.

To all whom it may concern Be it known that I, 'NOAH WALKER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in I Reversible Agitating Apparatus for Fluids,

of which the following is a specification.

One object of my present invention is to provide improved apparatus of simple and durable construction which will be operative to efiect the flow or movement of liquid in a container and in which the apparatus is capable of changing the direction of said movement of the liquid.

Another object is to make my improved apparatus of such construction that it will include two similarly operative propelling devices positioned relatively close together and actuated from a common source to effect said movement of the liquid.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a front elevation of my improved apparatus showing the same positioned relatively to a container; a portion of the container being illustrated in section,

Figure 2 is a view of said apparatus looking in an opposite direction from that in which the device is illustrated in Figure 1, and

Figure 3 is a side view looking in the di rection of the arrow at in Figure 1.

Referring to the drawings, I have illustrated my invention in connection with a container 12 having a horizontal partition or board 13. This container may be of any desired construction for holding liquid up to a level above the board; it being one of the objects of my invention to provide the apparatus for any purpose or condition to eflect the flow of liquid in an alternating manner upward and downward through the holes 14 and 14 in the board .13.

Referring specifically to the apparatus of my invention, 15 represents an actuating head including a base 16 which may be made of cast metal and adapted to set upon the top of the container 12, as clearly shown in Figure 1. A standard 17 has a flanged bottom 18 which is boltedto the base.

The standard 17 has a recess 22 which dep n m t t p surface and he pp r Serial No. 521,557.

sides of the recess are provided with bearing caps 25 and serve as bearings for a horizontally disposed transverse shaft 26; said shaft extending across the recess 22 and projecting beyond the'outer ends of the bearing portions 23 and 24 and caps 25. The standard 17 has opposed lateral projections 27 and 28 which at their outer ends provide bearings for two propeller shafts 29 and 30; said propeller shafts extending through holes in the base 16. Said projecting ends of the transverse shaft 26 have bevel gears 31 and 32 respectively secured thereto and which meshwith bevel gears 33 and 34 which are secured on the upper ends .of the propeller shafts 29 and 30 respectively atpositions above the lateral bearings 27 and 28.

The shaft 26 has a gear wheel 35 secured thereon; said gear wheel being positioned so that a portion of itextends into the recess 22. The opposite ends of the hub of the gear wheel 35 are adapted to abut the outer opposed end surfaces of the bearing portions 23 and 24 and bearing caps 25.

The propeller shafts 29 and 30 have blade propellers secured thereto; said propellers being located within the respective holes 14 and 14 of the board 13; the blades of said propellers being pitched at opposite angles so that when the propeller shafts rotate in unison in opposite directions they will serve to both move the liquid in the same direction through the holes 14 and 14*.

I mount upon thebase 16 power driven reversing means 36 of a suitable character. In the form of my invention illustrated said power driven reversing means includes a wheel 43 which can be rotated in either direction by the action of said reversing means. The wheel 43 drives the wheel 35 and thus the wheel 35 can be rotated in either direction and the propeller shafts and propellers can be rotated in either direction.

By the structure above set forth the liquid can be moved through the holes 14 and 14 first in one direction andthen in an opposite direction,

Reference is hereby made to my applicav 1,498,217 rarest c rries.

parts of the portions 23 and 24at opposite tion for U. S; Patent filed March 13th, 1924,

tion may be changed without departing from 111ySGlf to the precise construction set forth,

but consider that I am at liberty to make such changes and alterations as fairly come Within the scope of the appended claim. 7

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is In apparatus of the character described, a central supporting 'structure including upright portions spaced apart providing bearings; a transverse shaft mounted in said bearings; a driving Wheel mounted on said shaft and extending into the space between said upright portions; gear Wheels on said transverse shaft at positions outside of said upright portions; upright propeller shafts;

bearings at opposite sides of; said first supporting structure, said propeller shaftsbeing mounted in said latter bearings; gear Wheels on said propeller shafts meshing With the gear wheels on said first shaft; a base upon which said central supporting structure is mounted: and power driven reversing means on said base for rotating said transverse shaft and operative upon said first wheel in the direction of a plane passing between said upright portions.

In. Witness whereof I have signediny name to this specification in the presence of two subscribing Witnesses. I
