    2 A.D. 1873.—N° 3541. Provisional Specification. Milnes’ Improvements in Apparatus for Utilizing Sewage. comparitively free from solid matter; the sewage after passing the pits and grates may be caused to pass through filtering strata of divers sorts. The means I employ for removing the deposits from the pits are as follows:—On the crown of the sewer over each pit an opening is made B or left when built of a size to correspond to the size of the pit. Through this opening I lower a tube of iron or other material by means of a crane or other equivalent means on to the top of the pit; the bottom of the tube fits close to the top of the pit so as to exclude the flowing sewage at the top of the pit, and yet not hinder its escape past the tube. 10 The top of the tube I construct so as to conform to the shape of the opening in the crown of the sewer, so as to effectually prevent the escape of offensive gas during the operation of emptying the pit. I then lower a bucket or buckets with valves or moveable bottoms into the pit, and when the proper depth is reached I cause the said valves or bottoms to 15 be closed so as to retain the manure in the bucket, which is then raised by a windlass or equivalent means, and the manure is deposited in a cart or other receptical. Instead of a bucket or buckets I may prefer to employ an Archemedion screw or equivalent contrivance to lift the manure from the pits. 20 LONDON: Printed by George Edward Eyre and William Spottiswoode,
