Which- Figure l denotes a front elevation, and Fig. 2 a vertical section, of a pump lower box provided With my invention.
In carrying out such invent-ion I provide the box A with a conical or other proper shaped strainer, B, which I usually make ofiine wire netting or gauze, it being to cover tbe'mouth a of the box; and, furthermore, I arrange below such strainer, and connect to the box, an
Y auxiliary one, C, having' large openings in its the auxiliary strainer being made to encompass the main one. This auxiliary strainer is to catch and retain the sand and foreign matters that may t'all from the main stra-incr while water or a liquid may be iu the act of being drawn up through it, or afterward, and there-- by prevent such matters from dropping back into the inductionpipe, so as to gather therein.
By raising the box out ot' the pump-barrel the matters collected in the lower strainer can be easily removed therefrom, such-lower strainer also serving' to protect the upper one in other respects. v
I claim- In combination with a pump-box, A, and a main strainer, B, extended across the induct ot' said box, au auxiliary strainer, C, provided with one or more openings, b, all being substantially as represented.
