    Q A.D. 1857.—N° 2949. Provisional Specification. Manning's Impts. in the Treatment of Sewerage, and in Apparatus used therein. in by means of force pumps, whilst the other pipe admits compressed air into the vessel, which air is also forced in at a considerable pressure by the aid of air pumps. At the bottom of the inner vessel is a discharge pipe for the delivery or discharge of the solid matter into hermetically closed barges, or other convenient receptacles for the removal of the same. A cock or valve 5 is fitted to the discharge pipe and to the sewerage pipe, so that when the vessel is full the supply cock may be closed, and the pneumatic pressure will force the fluid matter through the perforations and charcoal into a third outer chamber or tank, where the water, now made pure and clear, is collected, and thence runs off in an innoxious state. The solid matter collects in the inner 10 vessel and is forced through the discharge pipe, when the cock or valve is opened by the pressure above referred to; suitable outlet pipes may be used for carrying off the gases if found desirable. In order to prevent the choking of the pipes which supply the vessel with sewTerage, I propose to construct depositing tanks at the mouths of the sewers ; such tanks being fitted with 15 gratings which will trap all large refuse matter and allow the ordinary solid matter to pass through to the bottom of the tank, where agitators are used for keeping the sediment from depositing. By this means the finer portion of the solid matter is kept well stirred, and is drawn up by the pumps, whilst the larger portions of the solid matter may be periodically removed by lifting up 20 the grating with the matter upon it and inserting another one. To facilitate this suitable shafts may be sunk at those places where the depositing tanks and gratings exist. The sewerage matter collected and carried off in the barges, before referred to, may afterwards be dealt with in any manner for the purpose of rendering the same applicable to the purposes of manure, &c. 25 LONDON: Printed by George Edward Eyre and William Spottiswoode,
