I is a discharge-pipe from receptacle, extending therefrom into the boiler A.

J is a Well in receptacle B, near the end thereof, from which discharge-pipe I extends.

K is a blow-off cock from Well J.

L is a dome on receptacle B.

M is a pipe extending from'dome L, and N is a bl0W-off cock in pipe M.

O is a deflector-plate in receptacle B.

The manner of operation of my mechanical purifier is as follows: When the injector C is opened, the feed-Water from the supply is forced therethrough through pipe D, nozzle F in injector E, and into the receptacle B through the discharge Gin injector E. At the same time hot Water from boiler A is drawn through pipe H and forced through discharge G into receptacle B along with the cold Water. Such hot waterin its passage through discharge G is intermingled with the cold Water discharged through nozzle F. The cross sectional area of receptacle B is considerably greater than the combined cross-sections of pipes G and II, (as Well as of discharge-pipe 1,) and the contents of such receptacle B are substantially at rest vWhile passing through the receptacle, there being a slow current through the receptacle toward the discharge end thereof when the injectors O and E are forcing Water into the receptacle B through such receptacle and into the boiler from the discharge end of the receptacle through pipe I. As such Water extends through the recep tacle B, the Water being in a highlyheated condition, the matter or substance desired to be taken from the Water Will be precipitated in the receptacle B, and Where, as I at all times prefer, the Well J and deflector-plate O are used such substances as are of greater specific gravity than the liquid contained in the receptacle B Willbe deposited in such Well J, from which it can be Withdrawn by open- -in g the blow-off cock K.

Where the dome L is used, substances of less specific gravity than the liquid contents of the receptacle B will be collected in such dome and can be'removed therefrom by opening the bloW-off cock N.

Having 'th us described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A receptacle for liquid consisting of a horizontal cylinder, an injector discharging into the receptacle, at one end of the cylinder on the upper side thereof, a pipe extending to the injector from an ordinary feed-wa ter injector, a second pipe extending to the injector from the boiler whereby hot and cold water are forced into the receptacle, a discharge-pipe through the center of the head of the discharge end of the receptacle extending therefrom back to the boiler, a dome near the discharge end of the receptacle, and a Well in the receptacle between the dome and the discharge end; substantially as described.

2. A receptacle for liquid consisting of a horizontal cylinder, an injector discharging into the receptacle at one end of the cylinder on the upper side thereof, a pipe extending to the injector from an ordinary feed-Water injector, a second pipe extending to the injector from the boiler whereby hot and cold Water are forced into the receptacle, a discharge-pipe through the center of the head of the discharge end of the receptacle extending therefrom back to the boiler, a dome near the discharge end of the receptacle, and a well in the receptacle between the dome and the discharge end with a deflector-plate extending from the upper side of the cylinder adjacent to the dome into the Well and near to the bottom thereof 5 substantially as described.
