CISTERN CLEANER.

SPECIFICATION forming part of Letters Patent No. 382,864, dated May 15, 18818,

Application tiled December 28, 1887. Serial No. 250,255. (No model.)

To all whom it may concern.'

Be it known that I, JOHN H. BREESE, a citizen of the United States, residing at Minne apolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Cistern- Cleaners, of which the following is a specification.

This invention relates to a portable device for taking up the sediment and contaminated water in cisterns or tanks without removing the whole contents thereof.

The object of the invention is to provide a device of this character of great simplicity and economy of construction, free from movable parts or mechanism liable to get out of order,

and in accord with scientific principles.

Figure 1 of the accompanying drawings is a central vertical section of this improved cisterncleaner in position at the bottom of a tank or cistern, ready to receive the sediment and dirty water therefrom. Fig. 2 is a similar view, the dirty water and sediment being represented as iiowing into the cleaner. Fig. 3 is an enlarged central vertical section of thisim proved cisternfclean'er.

Similar numerals of reference indicate corresponding parts in the different gures.

The hollow body 10 of this improved cisterncleaner is composed of any suitable material in any desired form, but is preferably constructed in the form of an ordinary vertical dasherchurn or truncated cone, and in such case the body is surrounded by hoops 11. This body is provided with a iixed bottom, 12, preferably located a little above the lower edge of the body. Short legs 13, projecting downward from the lower edge of the body, serve to elevate it slightly above the bottom of the cistern or tank into which it may be placed to permit the water to ilow under said bottom. The bottom 12 is provided with a central aperture, and atube, 14, xed to said bottom, extends through said aperture upward into the body of the cleaner and terminates below the top thereof. This tube is preferably provided with aiiange,15, through which screws 16 are passed for attaching it to the bottom 12. A supplemental sliding tube, 17, is telescoped over the tube 14 to render the latter extensible.

The top of the body 10 is closed by a removable cover, 18, which is secured to the body by suitable hasps or fastening devices, 19. The

'joint between the cover and the body is preferably provided with a packing-ring, 20, to render the joint air-tight. The cover 1S is provided with a central hole, 21, and opposite said hole with a socket, 22, for receiving a tubular handle, 28. The socket and handle are shown as screw-threaded. This tubular handle may be extensible, if desired, as shown in Fig. 1, and is provided at or near its upper end with a closing device, 24, which may be in. the form of a detachable plug, a turning plug, the hand of the operator, or in other equivalent form. The socket 22 may be castintegral with a disk or collar, 25, and a portion of the .fastening devices may be also formed integral with said disk, the disk being attached by nails or screws to the cover 18. l

The operation of this improved device is as follows: The plug or stop-cock in the handle being closed, the body of the cleaner is lowa ered or pushed down through the body of water or other liquid in the cistern or tank to be cleaned to the bottom thereof, as illustrated in Fig. 1, being held in vertical position while being submerged. The body being iilled with air, for which there is no escape during the sinking, no water can enter. As soon as the device is in position the operator opens the handle or removes the plug therefrom,whereby the air within the body is free to escape, and the weight of water in the tank causes water to rush rapidly through the interior tube into the annular space within the body surrounding said tube, from which the air is driven. This rush of water carries with it the sediment beneath and surrounding the body and lodges it in the interior thereof. The operator then lifts the body out of the cistern, takes off the cover, and pours out the iilthy contents. i This operation is repeated when the area of the cistern or tank to be cleaned is such as to require a repetition..

The object of the telescopic tube is to enable the interior tube to be adjusted to suit the height of water in the tank. When the water is not very deep, only a short tube can be emthe tube is elongated to a point near the top of the body, so that a larger quantity of Water and sediment can be removed at one operatiom ployed; but when the water is sufficiently deep- The advantages of this improved cisterncleaner are that the air is conducted through the tube and discharged above thelevel of the water, whereby the water is not riled by the escape of the air; that the body has a xed tight bottom which does not permit the filthy contents of the cleaner to escape into and contaminate the body of water in the cistern when the cleaner islifted out; that there are no valves in the body of the cleaner liable to become clogged by dead rats or large objects which may be found at the bottom of the cistern, and lno valve-hinges to get out of order. On the contrary, thetube is always open for the free entrance of the dirty water, sedimentand other refuse as soon as the air is permitted to escape from the interior of the body.

I claim as my invention l. Thecombination of a hollow body provided with abottom having an aperture, a tube open at both ends and extending upward from said aperture within said body and terminat ing below the top thereof, and a tubular handle connected to the top of said body, substantially as described.

2. The combination of a hollow body provided with a bottom having an aperture, an extensible tube open at both ends and extending upward from said aperture within said body and terminating below the top thereof,

and a tubular handle connected to the top of said body, substantially as described.

3. The combination of a hollow body provided with a bottom having an aperture, a tube open at both ends and extending upward from said aperture within said body and terminating below the top thereof, a tubular handle connected to the top of said body, and a closing devicefor said handle, substantially as described.

4. The combination of a hollow body provided with a bottom having an aperture, an extensible tube open at both ends and extending upward from said aperture within said body and terminating` below' the top thereof, a tubular handle connected to the top of said body, and a closingplug for said handle, sub stantially as described.

5. The combination of a hollow body provided with a bottom having an aperture, a tube open at both ends and extending upward from said aperture within said body and terminating below the top thereof, a detachable cover for said body, a hollow handle secured to said cover, and a closingplug for said handle, substantially as described.
