4 Claims.

This invention relates to an apparatus for cleaning cesspools as used in and around canning factories and is preferably built into the cesspool so that it is always installed and ready for immediate operation.

The general principle of the device comprises a circular top portion and a conical lower portion with a division wall about midway down into the circular portion. The conical portion leads to an ordinary drain.

Located in the conical portion is an elevator driven from a suitable source of power and adapted to collect the solid matter and convey it away to some suitable place of disposal.

The division wall is provided with half its area perforated to discharge the liquid portions of the accumulations in the cesspool and its other half imperforate except for a large opening just over the elevator.

Arranged just above the division wall and moving in close relation thereto is a sweep arm for moving the accumulated material around over the division wall to separate the liquid from the solids and have them discharge in their proper channels.

It is therefore a principal object of the invention to provide a cesspool cleaner that is power driven and permanently installed for immediate operation.

It is a further object of the invention to provide a cesspool cleaner that will be permanently installed and be provided with a division wall that will separate the liquid from the solids.

It is also an object of the invention to provide a cesspool cleaner wherein there is a moving element to agitate the accumulations to facilitate separation of the liquids from the solids.

It is also an object of the invention to provide a cesspool cleaner wherein an elevator is provided for accumulating the solids as discharged from the cleaner and convey them to a suitable place of disposal.

With such objects in view as well as other ad vantages inherent in the invention, consisting in the parts and combinations hereinafter set forth and claimed, it is understood that the several necprovements in their applications to the particular construction chosen to illustrate the invention.

Referring now to the drawing, Fig. 1 is a plan of the apparatus.

Fig. 2 is a. vertical section somewhat offset from the center to show the elevator in solid lines and the tank proper in central section.

Fig. 3 is a cross section of the elevator and housing therefor.` I

l represents the tank proper with the circular or cylindrical top portion and the conical lower portion.

2 is the division wall having the perforated section 3 and the imperforate section 4 with the opening 5 for the discharge of solids. 6 is the sweep arm that travels over the top surface of the division wall to move the material around and agitate it so the liquids and solids will separate readily.

'l is the elevator for receiving the solids that are passed through the opening 5, which may be of `any length desired or necessary to convey the material to a suitable place of disposal, and is made up of suitable chains 8 with flights 9 moving through the housing 10.

The sweep arm and elevator are driven by means of the belt 11 coming from a suitable source of power and the mitre gears l2 and 13 and 14 and 15 and short chain 16.

The liquid portion of the accumulations passes down through the cone section of the apparatus and passes through the opening 1'? to a drain.

The operation seems self evident without a special description. Material is dumped promiscuously into the tank l and with the arm 6 sweeping across the top surface of the division wall 2 the accumulations are agitated and stirred so that the liquid portions will pass through the perforations 3 and the solids will be swept through the opening 5, drop ontov the elevator and be conveyed away. 95

What I claim as new and desire to secure'by Letters Patent is:

l. An apparatus for accumulating a mixed mass of material and separating the liquid from the solids comprising a tank, a division wall in said tank one half of which is perforate and the other half is imperforate except for a discharge for solid material, means for agitating the material to better effect separation and means for accumulating the solid material and removing it to a place of further disposal.

2. An apparatus for accumulating a mixed mass of material and liquid and separating the liquid from the solids comprising a tank, a division wall arranged horizontally across said tank having a perforated portion adapted to pass liquid and an imperforate portion with a port adapted to pass solids, a sweeper arm for moving the mass over said Wall so separation can take place and separate means for receiving the solids and liq uids and moving them away.

3. An apparatus for accumulating a mixed mass of material and separating the liquid from the solids comprising a tank, a division wall in said tank and an open bottom in said tank, a portion of said division Wall being perforate for the passage of liquid and the other portion being imperforate except for a discharge for the solid portion of said matter, means for agitating said mass of material to cause the liquid to pass through said perforation and out of the bottom of said tank, a conveyor under the discharge for the solid material to receive said material and convey it to a place of disposal separate from the liquid.

4. An apparatus for Iaccumulating a mass of material and separating the liquid from the solids comprising a tank having an open bottom, a division Wall in said tank a portion of which is perforate for the passage of the liquid portion of said mass of material and the remaining portion of which is imperforate except for a discharge at one side of the center of said tank, means for agitating the mass to cause a separation of the liquid which passes through the perforations and out the bottom of the tank, a conveyor under the discharge for solid material to receive material from said discharge and convey it to a place of disposal separate from the liquid.
