In the drawings, 10 is a metal body in teriorly fashioned with a forwardly positoned clearance open space 11, said body be-1 ing preferably tapered at its forward end as at 12, the clearance space continuing through said tapered portion to the open end of the outlet portion 13.

The rear end of the body may be cast solid therewith as at 14, or cast separate and welded or otherwise secured thereto, said solid portion being provided with a centrally bored at its forward end with the inclined substantially concaved formed wall portion 16.

Raised portions 17 and 18 may be integrally formed in connection with the body and are provided with open ways respectively at 19 and 20 to facilitate entry-way 19 for the admission of air and 20 for the admission of oil.

21 is an air inlet pipe and 22 is an oil said ipe a nozzle is attached which is re ferre to generally as 24. The forward end nozzle is interned and its marginal edges relatively spaced to form the jet openportion 15 and is preferably fashionedL ing 25 and is also fashioned as at 26 in a manner to present inclined circumferential walls `leading to the jet opening.

v27 is a spirally fashioned block or filler member dimensioned to snugly fit within the interior bore of nozzle 24. The forward end of the block member is preferably fashioned on straight transverse lines to facilitate thru its abutment with t-he wall members of the nozzle a substantially conically shaped clearance way intervening between block member and nozzle opening. -l

28a is a spiral spring member interposed-y between the rear end of block 27 and an abutment portion within the nozzle adapted to hold block member 27 in proper functioning position. The construction of the nozzle as herein exemplied is one that is preferred because of convenience in manufacture.K However, the spiral block may as a matter of course be made an integral part ofthe nozzle or may be otherwise sup orted in connection with the nozzle as may desired.

In the practical working of my device it is intended that oil shall be delivered to the conductor tube and nozzle thru an open way which said open lway will serve as well to permit the entry of air delivered into the chamber portion of block 1.0. I have provided herein an open ended elbow fashioned member 28 attached to tube 23, the same being positioned to receive a gravity discharge communication with the oil inlet opening '20 in the block member.

33 is a valve member fitting within the central bore of sleeve member 30 and is fashioned with the right angled perforation 34 at its forward end that registers its opposed ends 'respective with oil in et opening 20 and a perforation in the forward end of tubular member 30 whereby when the tubular and valve supports are in register oil will be conducted for discharge into oil conductor tube 23. The valve stem 35 is provided to facili.- tate turning the valve to effect at option reg- .ister or non-register of the communicating ways from theoil supply tol the conductor way leading tov conductor tube 23, leakage of oil being guarded against as by means of stuling box 36, or by any other suitable means that may be desired.

Oil conductor tube 23 and its associated nozzle and elbow joint parts at its front end portion may be supported within a central bore within plate 37 which said plate may be fashioned in the manner of a taper as shown herein and fixed within the transverse area of the clearance supports within the block at a substantially angular juncture of the tapered walls of said block and may be secured in position by means of a set screw as 38. The rear end may be supported in the manner shown as by means of a bifurcated bracket member 39 connected with a rod member 40 that extends rearwardly therefrom and being carried in the longitudinal perforation in the cast portion 14 of body member 10, or rod 40 may if desired be rigidly connected with conductor member comprising tube 23 and elbow member 28.

For purposes of co-ordinating discharges of the oil and air mixture delivered thru tubular member 23 and nozzle 24 and the auxiliary air blast delivered thru orifice 13 at the forward end of block member 10, I have provided means for adjusting the nozzle and tubular member for optional longitudinal projection or retraction which means as shown consists of the rod member 40 and the screw threaded as at 41 and the screw member 42 thereon thru which thru relative co-operative action and in'conjunction with the rear wall of body member 10 said rod may be advanced or retracted at will.- To the end-that the rod shall be maintained in a definite position, screw member 43 actively connected with thel block member is provided, which may be utilized to fix the rod in a definite and determined position. Also coil spring member 44 is provided the same being seated in pocket 45 in the cast portion of body 10, said spring surrounding the rod and abutting its opposed ends respectively against the rear wall of said pocket and bracket member 39 thereby imparting a forward pressure against the air and oil conductor parts bein capable of adjustment under the tension o? said spring.

In the carrying out of the purposes of my invention it is designed that air shall be delvered thru air duct 21 into the open areaway within block member 10 and that such air may at option enter conjunctionally with oil thru elbow member 39 for mixture with the oil designed for ultimate discharge thru nozzle 24; also that such air supply may also be provided with an optional course exteriorally of air and oil conductor to provide a pure air blast for and about the nozzle dischange way. Further it is designed-that the auxiliary air supply shall be active under a limited resistance and that the discharge of the same shall be distributed and deflected for the purpose of producing a cone fashioned discharge and to this end I have provided a plurality of curved tubed member 46 which are supported at their rear ends in perfor-ations in plate member 37 and arranged in said plate in a circular manner about the axially disposed central opening in said plate thru which nozzle projects and that the forward ends of said tubular member shall be disposed in and about the nozzle substantially as shown and the forward ends of said tubular members may be attcned as at 47 if desired to facilitate the presentation of a comparatively long and narrow discharge way. IVith this relative arrangement of auxiliary air discharge tubes 46 with respect to nozzle 24, the air and oil and air blast may be so related as to bring about the best'combustion results, such regulation being accomplished as herebefore noted thru and by means of relative adjustment of said nozzle with respect to the clearance opening 13 in the forward end of block member 10.

In carrying out the function capabilities of my invention it is necesary that air and oil shall be supplied to the device under proper delivery means. However, as such requirement is well understood as being required in device in the ractical and patent art, I have not present any illustration of such compression means. I have shown herein my preferred form of embodiment of my invention. However, the same may be changed as to form, proportion and relative arrangement of parts without departing from the purposes herein contemplated, therefore, I do not desire to limit myself to the forms, proportions and relative arrangement of parts in exact detail :1s-herein exempliied but claim Vall forms that fall legitimately within the lprinciple herein disclosed.
