B` L. COUTANT 'EJECTOR Filed NOV. 50 1921 @lll/ l Patented June I2, 1923.

UNITED STATES BENONI L. COUTANT, OF JACKSONVILLE, FLORIDA.

EJECTOR.

Application led November 30, 1921.

To all whom t may concern:

Be it known that I, BENoNr L. COUTANT, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Ejectors; and I do hereby declare the following to be 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. n

My invention relates to certain new and useful improvements in ejectors of a type wherein fluids or gases under pressure are utilized for effecting the bodily movement o1 material.

An object of the present invention is to produce an ejector of comparatively simple construction formed of a single casing or housing, the ends of which areeasily packed against leakage and closed by novel end de-v vices which serve to support the suction and discharge nozzles of the ejector and also maintain the packing out of contact with both the inducing medium and the material being moved.

Another object of the invention is the production of an ejector in which the cooperating suction and discharge nozzles are centrally supported in adjustable relation, one toward the other, the adjusting means being located within one of the end closures and readily operated without danger or' distorting the effective relation of the nozzles or disloc-ating t-he packing and causing leakage.

A further object of the inventionv is to provide an ejector comparatively inexpensive. to manufacture and to maintain, in that the several parts used are standard fittings, and the quantity of packing heretofore used is reduced to the minimum,

Other objects will in part be obvious, ret erence being had to the specication and claims hereto appended.

In the accompanying drawings in which I have illustrated an embodiment of my invention, l i 4 Figure 1 is a longitudinal sectional view through my improved ejector; n

Figure 2-is a transverse sectional. view von the line 2-2 of Figure 1; and y Figure 3 is a transverse sectionalview on the line 3 3 of Figure 1.. i, y

My present invention has been designed with a view to producing an ejecting device capable of many uses, someof whichare Serial No. 518,910.

eral parts as properly fall within my invenf tion as rhereinafter particularly defined.

Referringto the drawings, the ejector includes a sleeve casing 1 about the suction and ldischarge nozzles and serving to house the several parts in a compact and particularly neat manner. The interior of the sleeve forms the chamber 2 into which fluid,y air or other gas is admitted under pressure through the inlet 3, the boss l of which is preferably formed integral with the sleeve 1 as shown. Any suitable conduit may be attached to the inlet, and the inducing material of the ejector admitted from any suitable source of supply (not shown). l

Located within the sleeve 1 are two nozzles cooperatively associated and termed `for purposes herein, a suction nozzle 5 and a discharge nozzle 6. f

The suction nozzle 5 is relatively long and extends into the sleeve 1 a distance slightly beyond the inlet 3 as shown. The outlet end 7 of the suction nozzle 5 is beveled as :shown at 8 and together with the inlet beveled end 9 of the nozzle 6 permits the forming of a hollow cone-like `jet of fluid or gas in its pas sage from the chamber 2 through the discharge nozzle 6, thereby inducing suction in the nozzle 5 andpmovement of the material therethrough in the direction of the arrow shown in Figure 1.

The respective innermost ends of the nozzles 5 and 'are spaced from and supported centrally yof the sleeve 1 by means of the spider-like frame 10.` Each spider is provided with an opening 11 into which the nozzle end 'is fitted, lthe arms or projections 12 bearingagainstthe interior wall of the sleeve as shown. In practice these spiderf like supports can be secured either to the nozzle when assembling and inserted within f the sleeve, or they can be attached to the in? terior oit' the said sleeve and the-nozzle ends inserted therethrough as will be Aunderstood. It will be 'seen however that a rigid support is provided :tor the respective ends of the nozzles which will not interfere with the free passage of the inducingl medium in ythe chamber 2, and that the relative adjustment of the nozzles one toward the other is readily permitted Without distortingthe alinement oi said nozzles. rIChis I regard as an important factor, and together with the additional nozzle supporting means now to be described, constitutes a simple and controllable feature for ejectors never before known.

The respective nozzles 5 and 6 extend through andare supported by novel end closure devices 13 and 14. The closure 13 comprises a collar l5 slidably mounted upon the nozzle 5, and provided with a threaded flange 16. The flange 16 vscrews into the interiorly threaded portion. 1T of: the sleeve 1. Set screws 18 pass through the collar l5 and engage theA nozzle 5 and more especially slightI depressions'l) *formed therein. The collar 15 serves as a support for the nozzle 5v and the set screws permanently establish `its relation to the sleeve as iixed or station- 20 ary.

Associated with the flanged collar 15 is a capsection 2O arranged and adapted to be threaded upon the exterior threads 21 of the sleeve l. A packingmaterial 22 is interposed between the collar 15 and the cap 20, the latter being screwed relatively tight against the packing to prevent leakage.

The hend closure la is ot' similar construe a tion and includes the flanged collar 23 having a threaded portion designed to be screwed into the interiorly threaded portion 24 of the sleeve l. Set screws 25 pass through the collar 23 and are adapted to engage relatively long or groove-like depressions 26 formed in the sleeve 6. rlhe nozzle 6 is slidably mounted in the collar 23 and is adjustably held therein by means of the set screws 25. A cap 27 is associated with the collar 23 and is screwed upon the exterior-ly y threaded end 28 of the sleeve l. Packing material is interposed between the cap end vand collar, said packingbeing easily introduced and removed fromany direct. contact with either the induction material or the substances being` moved. A lock nut 2() is abutted against the cap 27 as shown.r said nut being rscrewed upon the threaded portion 80 of the nozzle 6.

' In operation, any fluid such assteam, or

any gas such as air is admitted under pres- .slui'e'to the chamber 2 from where it finds its way in a hollow cone-like spray between the interior and exterior beveled ends 8 and 9 of thenozzles 5 and 6. The angle of the bevels induces forward travel ot the spray'in the' direction of the arrow strong enough to produce 'suction in the nozzle or pipe 5.

`The''material beingv moved is drawn or ysuckedthrough the nozzle 5 and discharged "al`ong with the current of the inducing material out of the discharge nozzle 6. Any i suitable connection can be attached to the nozzle 6 for facilitating the delivery oi lthe Tnaterial to the desired destination. For iny stance, in cleaning cars, as an example, I attacha hose to the nozzle G and allow same to hang out the car window. I then direct a vcurrent of compressed air from the air line of the car through the ejector as the inducing medium, connecting a suitable suction nozzle to the threaded end oi' the pipe or nozzle 5. j

In regulating the flowing intensity of the inducing medium, the cap 2.7 is unscrewed and the set screws 25 loosened, whereupon the nozzle 6 can be moved toward or away 'from the nozzle rIhis movement is etected longitudinally 01"' the ejector and by reason of the collar and spider supports does not permit of any change in the longitudinal alineinent of the nozzles, thereby keeping the annular spray opening of uniform contour, but varyinO necessarily the quantity oi' induction material admitted.

I prefer to have but one ot the nozzles adjustable, but itwill be understood that I do not limit myseli1 to the one shown and described herein; nozzles 5 and 6 may be movably associated toward and away from each other.

Having thus described ,my invention what I claim is:
