AUTOlVfATlIC CELLAE-IURAXNER.

To all whom t may concern:

Be it known that l, ALEXIS R. Prism, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented eercjtain new and useful improvements in Automatic Cellar-lDrainers, of which the following is a specication, reference being had therein to the accompanying drawings.

The invention relates to an automatic drainer for cellars, sewers and other excavations arranged to discharge water noiselessly therefrom without attention by the user, the parts being so disposed as to be accessible for repair or replacement and being otherwise arranged to combine simplicity with accura-cy of operation.

'llhe invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claim.

ln the drawings, Figure 1 is a view in vertical section of an apparatus that embodies features of the invention; and lFigs. 2 and 3 are views in section showing1 a modification of an ejector.

As herein shown an ejector casing 1 has a pressure inlet arm 2 opening into a conical throat 3 with a discharge outlet nipple Il to which a suitable drain pipe 5 may be connected. A suction nozzle 6 is removably secured in the casing with its jet mouth concentrically within the throat 3. A suction pipe 7 is connected to this nozzle. rlhe lower end or mouth ofthe suction pipe is suitably secured in an opening of a dome 8 on a cage 9 that may form a foot rest for the drainer and at any rate has an apertured side wall as a strainer. An outwardly closing check valve may be placed in this cage and may be of any suitable design. As shown herein an annular valve seat 10 is sealed by a vertically movable closure 171 held in a depending stem 12 that reciprocatesin a guide bushing 13 of the cage. `Stop pins 1A may limit the upward movement of the closure.

` A Hoat operated-valve controls the How VV'through the inlet arm 2. This may be of any type, but preferably, consists of a casing 15 havin a air of alined valve seats 16 with a dou le anged closure 17 thereon,

this closure being arranged to have a balanced action. A stem 16 depending from the closure, passes through a suitable packing gland 19 and a guide bushing 20 in a depending arm 21 of the casing. A float 28 has a central guide sleeve 22 loosely reciprocable on the stem, adjustable stop collars 23 limitings its movement.

lin li1 igs. 2 and 3 a modification of the ejector is shown in which the exhaust opening 241 is directly in line with a jet nozzle 25 that is supplied through a pressure inlet 26, and is disposed in the interior of the casing in substantial alinement with the suction inlet 2'? and the passage or interior of the casing that connects this suction passage with the outlet 2li. ln both constructions the jet nozzle, either suction or pressure, is removable and interchangeable with other jet nozzles to vary the proportions and consequent capacity of the ejector, or to meet different conditions or requirements of service. lWhen the water level in the place in which the drainer is inserted, has reached the level sufficient to cause the iioat to raise the stem, the ejector at once proceeds to draw water through the suction pipe owing to the aspirator action of the throat and suction nozzle and continues such action until the float has fallen sudiciently to close the valve. The limited movement of the float independently of the valve allows the collection of a certain amount of water around the drainer before action results. While the foot valve or check in the suction pipe is an advantageous feature it need not be used unless desired.

Ubviously, changes in the details of construction may be made without 4departing from the spirit of my invention and l do not wish to limit myself to any particular form or arrangement of parts.

What l claim is j n an automatic drainer, the combination with an ejector having a drain pipe, and a suction pipe vertically alining therewith, of a cage supporting said suction pipe, a pressure inlet arm carried by said ejector intermediate the ends thereof, a valve carried by said arm for admitting fluid under pressure 2' Liieiez to seid ejector, e depending 2guide erm carfied by said Valve, a Valve stem extending through the arm of seid Valve into saidyalve to control the Supply of iluid to said pressure inlet arm, adjustable Stop collars on said Valve stem, and e float movable upon said Valve stem and limited in its movement thereon by said stop collars and adapted to i actuate seid stem at e time determined by the Volume of liquid to be drained. lo ln testimony whereof ll eiiix my signature in piesence of two Witnesses.
