SPECIFICATION forming part of Letters Patent No. 295,293, dated March 18, 1884.

Application filed February 21, 1883. (No model.)

To @ZZ zutont t may concern.:

Be it known that I, LoUIs SoHU'rrn, of Phiiadelphia, in the county of Philadelphia, in the State of Pennsylvania., United States of America., have invented certain new and useful Improvements in Jet-Ejectors, of which the following is a specification.

The present invention consists in the peculiar construction and relative arrangement of the severai parts oi' a steani-ejector for the purpose oi' producing an apparatus of the smallest possible size in cross-section.

Itelerring to the accompanying drawings, Figure 1 represents a vertical central crosssection of my apparatus. Fig. 2 is a side'elevation ot' the same. on the line of Fig. 1.

In proceeding to construct my apparatus I iirst cast complete in one piece a body, I, of the forni represented in the drawings, with two attened sides and a semici'rcular lower end. vWithin this body there is formed a revertible opening or passageVG, which communicates at its upper end near one side of the body with a tnbular neck or throat, which is threaded eX- ternally to receive the couplingi'or connecting the steam-pipe D therewith. At its opposite and inner end the passage GfV terminates in a steam-nozzle, A, the mouth of which is extended in an upward direction. At its lower end the body has formed upon it a tubular central neck, which is threaded internally to receive and suspend the suction-pipe F, through which the water or other fluid to be elevated may be drawn into the apparatus. Into the top ofthe body, directly over the nozzle A, I screw the combining-tube C, the lower end of which is expanded to encircle the steam-nozzle A, and the upper end of which is made of iilcreasing diameter toward its delivery end.

It will be observed that the tube C is provided with au external thread and screwed into place in the top of the body I, this construction permitting the tube to be readily re- Fig. 3 is a cross-sectionmoved in order to give access to the interior ofthe apparatus in the event of its becoming necessary.

To the upper end of the mixing-tube C-,I connect, by asuitable coupling-joint, the vertical delivery-pi pe E;

It will be observed that the steam-pipe D and delivery-pipe E stand in a vertical position, and that they connect with the top of the body near opposite sides thereof, so that they serve jointly to sustain the weight of the body and ofthe pendent suctionpipe F. This arrangement admits ofthe Weight being distributed between the two upper pipes, and also disposes of the weight in such manner that the devices have little or no liability to vibrate when in action.

Around the steain'pipe D, concentric therewith, I mount a second pipe, H, the lower end of which is attached to a coupling to receive the steam-pipe.

pipes D and H for the purpose of preventing the condensation of the steam by the cold fluids in which the apparatus is ordinarily submerged.

I am aware that various ejectors have been constructed with steam and delivery pipes at the top and a suction-pipe at the bottonnand LOUIS SCHUTTE.
