“ That patent shows a portable receiving cask connected from its top, by a flexible pipe, with the vault, and by another flexible pipe with an air-pump, which has secured to it a deodorizing vessel. The air is exhausted from the cask and passes through the air-pump into the deodorizer, and the contents of the vault rise into the cask. The cask has no heck-valve, and is described as placed suitably near the vault. ”

“ There is an air-pump, by means of which a vacuum can be formed and maintained in the cask, and a deodorizer, through which the air drawn into the pump is expelled by the working of the pump. The suction-pipe and the air-pipe are both of them tubular, flexible connections. There are caps for closing the necks after the barrel is filled. There is inside of the cask no check-valve, but there is a float-valve, so arranged with reference to the opening of the air-pipe that the fecal matter lifts the valve and closes the passage when the barrel is sufficiently full. ”

“ After removing the seat or floor, the receptacle, B, is suspended from a block and tackle over the opening, and the cask or receptacle, B, is then lowered into the vault until the funnel, O, enters the fecal matter about ten inches, whereupon, by operating the suction-pump, the receptacle or cask becomes filled with the feces until it reaches the float-valve, f, which presses against and closes the orifice of the tube leading to the pump. ”
