This invention relates to an orderly and satisfactorily usable implement expressly designed to cooperate with a suction pump or the like to expedite and render easy the satisfactory removal of accumulated sediment from a cistern or similar water containing reservoir.

It is a matter of common knowledge that persons in sparsely populated areas are often dependent wholly upon the use of cisterns for their home water supply. At best, cisterns are objectionable in that the water not only becomes stale, but is frequently contaminated and rendered substantially unt for human consumption. To a large extent impurities in the water can be traced to lthy sediment which accumulates in the bottom of the structure. Thus, periodical cleaning of the cistern is necessary if sanitation is to prevail.

Many make-shift ways and means are resorted to in cleaning a cistern, Frequently, it is necessary to substantially empty the cistern in order to satisfactorily clean out the accumulations and sediment. Since the cistern relies for its water supply from rain water entering through a downspout, it is not always convenient r practicable to bail out the water, since the supply can be rep-lenished only bly a downfall of rain. Repeatedly faced with these inconveniences I have discovered the need for means which may be relied upon to satisfactorily suck out the sediment without materially disturbing the main body of water. It follows therefore that the present invention has to do with an implement where-in the principal novelty resides in the construction of a satisfactory intake nozzle usable in connection with a carry-olf pipe.

Other features and advantages will become more readily apparent from the following description and drawings.

In the accompanying drawings wherein like numerals are employed to designate the corresponding parts throughout the views:-

Figure 1 is a View showing a conventional cistern structure and illustrating the manner in which the sediment removing and cleaning tool or implement is utilized.

Figure 2 is an elevational View detailing the nozzle which, as before stated, is the essence of the invention.

Figure 3 is a bottom shown in Figure 2.

Figure 4 is a central or transverse sectional plan View of the nozzle view through the structure illustrated in Figure 2.

Figure 5 is a fragmentary detail view showing the pipe connection.

Figure 6 is a fragmentary elevational view of a portion of Figure 2 observing it from the opposite side.

In the drawings in Figure 1 the cistern, which may be of conventional construction, is denoted by the numeral 1. It is provided with an entrance opening 8 and suitable rain spout and vent pipe connections. So far as the invention is conl0 cerned the construction of the cistern is of course immaterial and cisterns obviously Vary in construction. The sediment to be removed is denoted by the numeral 9. The sedime-nt carryoff pipe is indicated at IU and is connected with l5 a pump or other suitable suction means (not shown). It is utilized as a handle so that the tool can be swung back and forth and properly manipulated within the restricted water containing compartment. The lower threaded end of the pipe is joined to the threaded iitting I I on the neck I2 of the intake and scraping nozzle I3. The nozzle I3 is in the form of a suitable light weight one-piece metal casting and is preferably semi-circular inside elevational view. In addition to being substantially crescent-shaped, the nozzle as shown in Figure 4 is generally tapered in transverse dimension as indicated at I 4 in Figure 4. In practice the nozzle is used With a sweeping and shovel-like motion and for this reason the bottom or extreme lower end I5 thereof is inclined and provided with a plurality of intake ports I6 which form a grid or screen through which the sediment is drawn by the suction produced through the pipe line I. Surrounding the grid-like tapered bottom is a rim including a main longitudinal ange I'I, and transverse end flanges I8 having somewhat the same inclination as the apertured bottom I5. These three flanges Il and I8 coordinate with the bottom in 40 defining a scraping and shovelling adapter pocket. Thus, the sediment can be collected in the pocket and sucked up through the openings IS without undue clogging. Or to state the problem otherwise the flanges I'I and I8 cooper- 45 ate with the apertured bottom I5 in providing effectively controllable scraping and accumulating means to loosen the sediment and to allow it to be evacuated through the nozzle and handle forming pipe I. Under ordinary circumstances this simplified and economical tool satisfies the need and can be operated in an orderly and effectively controllable manner. In practice, it has been observed that the nozzle head is gentle in its operation and removes the sediment rapidly and continuously without unnecessarily stirring up the sediment or mixing it with the water above. It follows, therefore, that this broomlike nozzle equipped tool or implement is a highly satisfactory cistern cleansing accessory or dev1ce.

Attention is called to the wide area of entrance provided by the apertured grid-like bottom l5 in relationship to the restricted discharge neck I0. Further emphasis is attached to the guardlike flanges I3 and I9 mutually cooperating in facilitating the scraping, pocketing and intake action.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considerin-g the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary. A

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

I claim:-

In a cistern cleansing implement of the class described, a relatively flat hollow nozzle forming head provided with a downwardly and forwardly inclined apertured bottom and longitudinal and transverse coordinated guard flanges depending below said bottom.
