FLUID-EJECTOR.

SPECIFICATION forming part of Letters Patent No. 372,024, dated October 25, 1887.

Application led March 5. 1887. Serial No. 229,42. (No model.)

To all whom, it may concerns `pipe, but below the ejector.

Be it known that we, CLARENCE, M. KEMP 'and CHARLEs E. KEMP, citizens of the United States, residing at Baltimo-re, in the State of Maryland, have invented certain new and useful Improvements in Fluid-Ejectors; and we do hereby declare the following -to ybe a full, clear, and exact description of the invention, such as will'enable others skilled in the art to which it appertains to make and use the same.

Cur invention relates to that class of Huidejectors illustrated and described in Letters Patent No. 356,647, granted to us January 25, 1887, in which a valve is located inthe supply-pipe leading from a main, and the valve-operating mechanism is given a quick movement to produce a sudden pressure through the ejector, and thus give an effectivemomentum to the static water.

' Our improvements consistinchanges in the form of the valve and connectingparts,where byit can be located and operated in the press" ure-pipe without being inimmediate connection with the ejector and set in any direction, vertically, horizontally, or at an angle,without changing its parts or operation. It is illustrated n the accompanying drawings, in

,which- Figure l is a side view, partlyin section, in position in a well or tank; Fig. 2, aview when used in a horizontal position; Fig. 3, a detail partly in section, and Figs. 4, 5, and 6 details.

In the drawings, A is awell or other receptacle from whichwater or other liquid is to be ejected; B, a pressure pipe; C, an ejector, and D the discharge-pipe.

In the form illustrated in the drawings, the valve and valve mechanism are located on avertical line with the ejector and discharge The valve portion is composed of an outside casing, E, a central chamber, F, and a lower water-chamber, G. yThe pressure-pipe is connected to this water-chamber. To one end of the valvecasing is connected the ejector C, which at its opposite end is connected to the discharge- 1 e. p LLI is a valve on a stem, I. It is located in the water-chamber G, andcloses the passage m between that chamber and the chamber F. A N is a gnide,which may be cast on the valveseat o, or otherwise'connected thenewith. The

stem I is passed through this guide, and is directed and steadied thereby so as to hold the valve squarely to the under side of the seat o. The guide is channeled to permit the liquid to pass up around it. The valve-stem is provided with an upper collar, p, and a lower collar, 19.

R is a spindle, provided with a flange, r, to which is attached a crank-arm, r. It is passed through a boss, r2, on the valve casingcrank extends between the collars p p. The crank acts as a lever, as hereinafter described, and a cam or other suitable mechanism may be substituted therefor. The boss r2 is screwthreaded internally, into which is inserted a screw cap, S, through which the spindle R is passed. The inner end of the cap, when screwed into the boss, forms a seat for the iange 1' of the spindle and also a tight joint at that point. A collar, s', on the cap its snugly against the boss. The spindle R turns in cap S and boss r, and it is cut out alittle at its central portion, r3, in order that it may turn thehmore freely.

L is a lever, keyed tothe end of spindle R and provided with a float, W. Instead of a cap, S, alug can be used, bored for the spindle The with an opening and plug on opposite side of 8o casing for the introduction of spindle.

The ejector C andthe valve-casing, as before suggested, may be placed vertically,lhori zontally, or at an angle, or the valve-casing may be placed in one directionand the ejector in another.

In Fig. 2 the valve-and casing are shown in a horizontal position and the ejector and discharge-pipe at a right angle therewith.

The operation of the apparatus is as follows: Before the valve is operated the water or other liquid from the pressure-pipe fills the chamber G, thus increasing the head-pressure,which acts against the valve H, aiding to hold the valve against its seat. As the water or liquid in the receptacle or cellar rises above or surrounds the ejector, it flows therein through ports c c?, and as it continues to rise it lifts the float and lever until the spindle R is made to revolve, which movement actuates the crank or cam, turning it against the lower collar, p', of the valve-stem and forcing the valve from its seat. At that moment the water from the pressure-pipe and water-chamber rushes in above the valve, giving to the valve a quicker throw, continues on through the central chamber, giving to the water in the ejector such momentum as to create a vacuum, whereby the water in well A is discharged through discharge-pipe D, until the water in well A has subsided, and the float and lever, falling therewith, the crank-lever r is carried against the upper collar, p, partially closing the valve, when the rushing water from chamber G to E through ortice m carries the valve the balance of its throw and seats it.

The operation is automatic and the receptacle can be almost or altogether drained, according to the situation of the valve-easing and ejector. y

lt will be seen by our improvements that little or no packing is required, the valve when closed being Iliade watertight not only bythe weight of the float, but bythe pressure of the water-the greater the pressure the more tightly is it held closed. As the cranklever working the valve is within the valve` chamber and acts directly upon the valve and is located 011 the discharge side thereof, the parts are free from friction and respond quickly and freely to the action of the lloat-lever and the water-pressure. By the water-pressure against the rim or flange on the spindle a tightjoint is also formed at the pointof connection of screw-cap and spindle head, thus avoiding the use of packing there. By our improvements, also, the ejector need not be immediately connected with valve, but may be placed at any desired distance from the valve, and two or more ejcctors may be employed, if desired, and set in any desired po- Sition.

XVhat we claim isl. ln a device for ejectiug liqhids, the combination ofthe pressure-pipe, discharge-pipe, and ejector with a valve receiving motion from a loat and lever, with connections extending into interior of valve-frame and there engaging with valve.

2. The combination of ejector and pressure and discharge pipes with a valve receiving motion from a lloat and lever, with connections extending into interior of valve-frame and there engaging with valve on discharge side of saine.

3. In combination with the valve and its connections, the spindle or lever provided with a flanged head or collar and plaeedwithin the valve-casing, and forming a seat or joint against the inner part of casing or cap, and a float lever for operating the said spindle.

4. The combination ot' the pressure-pipe, discharge pipe, and ejector with a valve located in the pressure-pipe, receiving its movement through a float or diaphragm, and connections making a turning or revolving movement.

5. The combination of a prcssure-pipe with a ioat and connections, a valve moved positively a certain distance by means ofthe float and connections, and the balance of its throw quickly by the fluid-pressure and the detachable ejector, whereby the ejector can be placed at any desired point on the pressurepipe away from the valve, substantially as described.

6. In combination with the valve-chamber and fluid-chamber, the valve mechanism composed of the valve, valve-stein, guide-plate, .and collars on the valvestem, and the spindleearrying the crank-arm to operate between Said collars, substantially as and lfor thc purpose described.

In testimony whereof we affix our signatures in presence ol' two witnesses.
