145 Lowe, George Gregory, 2 High Street, PortlandTown —Inventor.

Self-cleansing sanitary cistern. By affording facilityfor the rapid and entire discharge of its contents, thisinvention proposes to prevent the accumulation of filthand sediment in house cisterns; and, by conducting thewaste and discharge pipes into the house drain, both topreclude local dampness arising from overflow, and effec-tually to cleanse the latter by constant flushing.

Though the cylindrical form of cistern with a conicalbase is, in all cases, preferable, the principle of this inven-tion is equally applicable to any other form which maybe topically convenient, and to any material used in theconstruction of cisterns.

The novelty of the plan is stated to be that of passingpersons from the window of the house on fire to the nearwindow of the neighbour’s house adjoining, in a directhorizontal line, right or left, in lieu of lowei*ing themdown as in the ordinary way. This is accomplished byhaving bracket-hooks of a peculiar construction, pro-jecting about 12 inches from the face of the brickwork,permanently fixed to the front of the house at the upper-most floor, by passing the end or stem of the hook throughthe brickwork, and screwing up the plates tight by nuts
