'Application med June 89, 1928. -Serial No. 289,250.

This invention lrelates to a device for in' jectingmaterials into an air stream or body of fluid substance, and relates partlcularly to an injector device especially suitablefor adding a 'fluid', 'such as oil, in atomized form,

to' the fuel mixture being drawn into the cylinders of an internal combustion motor.

The most extensive utility of my invention is' in' combination with'internal combustion motors, as above indicated, wherem it is employed to deliver continuously a predetermined amount of atomized lubricant into the' air and hydrocarbon mixture constituting the fuel stream of the m0tor,for

the purpose of. lubricating those partsof the motor forming part of, or being as sociated with, the upper part of the-engine cylinder, or what is commonly known as the of the 'character designated, in which a very ellicient and constant delivery of oil v is accomplished, in' which the quan- -tity of oil delivered may be controlled to '25 vsult the conditions required by any gasoline engine, in which all of the lubricant placed in the deviceis used, and in'which simplicitfy. and economy of-producti'on of a device this character is accomplished.

'30 Further objects and advantages willi-be made evident throughout the following parts of the specification. Y

vReferring to the drawing which is for illustrative purposes only,A Y Y 35 "F'g. 1 is a vertical cross-section throu h a device embody' g the vprinciples and e e- 'f ments of the invention. Fig. '2 is a section derived on theplane re resented by the line 2-2 of Fig. 1.". 31's a view showingthe bottom of the Ijuncture plate used in this 'preferred -form of the invention at the lower ends of the induction and transfer tubes.,

Fig. 4 is a fragmenta sectional I'View `ing the invention.

In the embodiment of the invention shown i'n Fig.' 1,' I'employ a hollow 'receptacle'. 10

seating another form-o deviembodyconsisting ofl-'a`cup-like body' or v'e'sse'el"4 11 e0 and aca'p 1 ortion 12 vsecured to. the utler 'open end o the vessel 11i 'by -some'sui le means such as by 4interengaging threads' 13,

there'being a dividing late v1'4 situated-'ML- tween the vessel 1 1' an the cap 112 serving y 515 to divide the 'interior of the into -device is vattached Tis in o 'a primary compartment 15 anda secondary compartment 16. `Extending ,de wn from the upper part 17 of the cap 12 is 'an air l 'inlet pipe 18 which has communication with the exterior through suitable apertures such as the holes 19 which extend laterally vthrough the wall of a recessed plug. 20 threaded into the upper wall 17 ofthe cap 12, this plu 20 bemg removed when it 1s desired to'ii' l the lower chamber 15 with a liquid. The inlet pipe 18 projects through an opening 22 in the dividing Wall 14, and has on its lower end the juncture plate or body 23. v

A member 24, which for the purpose of description shall be termed the elevator or transfer t'ube, extends upwardly 'frein the juncture plate 23d in position adjacent and parallel to the'inletpipe 18 and projects' through'the dividing plate 14. The junc-v ture plate 23 is proximate to contact with lthe bottom' 25 of, the' vessel 11. and has recesses 27 formed in the' bottom 'thereof' which are preferably in the form of grooves" communicating with the' lower open en'ds of the members 18 vand 24 and extendin .to vthe sides 28 ofthe juncture fplate 23.v he receptacle O is provided with an outlet" 30 situated in the cap 12, this outlet being threaded or otherwise suitably equipped for attachment of a tube 31 for connecting the combustion'motor. Disposed between the device with the suction side of an internal outlet 30 andf the compartment 16v is a wall 33 having anopening 34 which maybe fully or partly closed by aJilow regulating screw;

' preferably inthe orm of a knob.

When the .combustion .motor to which the 35 threadedinto the upper wall 17 of thevv is "exerted through the tu '31 on the inte- .v

rior of the compartment 16', creati 'therein' a'condition of partial vacuum which' is in turn transmitted throug'ha nozzle .38

in the Adividing plate'14-to the upper-'portion of the primary'compartment 15 ix'i'which a oil 'isplaced as indicated at '39. The

' Pressure 'existing' on the 'exterior of 'the receptacle 10 causes'air to owinwardly Ythroughthe inletpipe` 18 as indicatedfbyY 18' flows laterally under the juncture plate a5 ration, a suction of the elevator pipe 24 through which it may u passing up through the elevator tube 24 into the secondary compartment 16 and part passing up through the body of oil, as illustrated by bubbles 44.

That portion'of the air which passes up through the elevator tube 24 is in open contact with the liquid in the lower compartment, owing to the `fact that the intercommunicating channel 27 is open on its lower side. Such condition insults in liquid being lifted or elevated through the tube 24 into., the upper compartment 16, `from which it normally would flow back `into the lower compartment 15 through the orifice 38', by gravity. The portion of air which bubbles' up through the liquid body in the lower compartment, as indicated at 44, picks up fine* particles of liquid from the liquid body fill-V ing or partly filling the lower chamber 15. This flow of air in seeking outlet must pass through the orifice 38 which is rovided with upwardly turned enclosing wa 1s whereby to give a nozzle effect and to produce a decided atomizing effect on the liquid which is see-k ing to flow down through the orifice 38,

fthereby subjecting the air to an additional and principal impregnation by atomized parbe ticles of liquid, which liquid in the present illustration of the invention may be understood to be lubricating oil. The flow of air, which passes through the elevator tube 2 4 also' causes atomizationof particles of oil which is being elevated, therefore, all of the air lstreamwhich passes out through the outlet 30 of vthefdevice is'amply impregnated with lubricant suitable for treatment of the enginecylinders and their associated parts. The amount of lubricant delivered to the engine may be regulatedby manipulation of the member 35. Although I have in Figs. 1, 2 and 3, shown the preferred form 'in which idesii-e to practice the invention, it is" possible to employ the several combinations of elements compnsing'the'inveiitions in other forms, as will be recog'mz'ed from Fig. 4 in which 50 indicates the lower rtion ofa cup or container which is divided by'horizontal wall members into chambers 51, .'52, 53 and, 54. 'I he wall members 55, 5 6 and 57 are respectively perforated at 58, 59 and 60, to permit the air inlet pipel-to roject down into the bottom chamber 51. he lower end of the member 61 projects through a plate 63 having a flat lower lsurface instead of the grooved lower surface employed in the preerred forml ofthe' invention.. The aii'l which flows through the inletpip'e 61 into the lower chamber is; spread outilaterally by the plate which surrounds the discharge end of the air inlet member, part of this air flow entering and rising thrqu h a transfer or 4elevator tube 65, through w ch the flow of air carries liquid into the second chamber -52. -A part of the air which has'entered through the inlet pipe 61 bubbles up through the body of liquid 66 which has been`placed in the chamber 5l and passes successively through the orifices 58, 59 and 60 which may or may not be provided with\ upwardly or downwardly directed enclosing lips, and

,which orifices are shown of annular form owing to the passagetherethrough of the inlet pipe 61. Each lof the chambers 52, 53 and 54 ma be fed with, liquid which is drawn upt rough interconnecting elevator tubes 70, and 71, as shown. In Fig. 4 the progress of the air in upward direction4 is indicated by 'arrowsf72. It will be noted that in this alternative form of the inventionthe'various principles of the invention are employed, although the general appearance of the structure may differ from the preferred form. It is intended that the scope of the invention shall not be considered -as confined to-this simple disclosure, but is to be limited only by the claims. Fclaim as my invention:
