To all whomz't may concern.
Be it 4known that I, PIERRE PLANTINGA, a citizen of the United Statesnresident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Oil Sprays for Carburetors, of which the following is a'speciication, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. g 7
This invention relates to a spraying device which is particularly useful in connectionl with -carburetors and has for its object to provide a spraying device capable of distri uting the oil in a rain spray throughout the entire area of the checker brick and so constructed.y as to be capable of withstanding the high temperatures ofv the carburetor chamber. A further object of the invention is to provide a spra nozzle that will properly distribute the oil at low pressures as well as at high pressures making it possible to regulate the How of oil by varying the pressure under which it is supplied to the nozzle, making it unnecessary to provide adjustable flow regulating means in the nozzle. i
The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of tlie various mechanical forms inf which the principle of the invention may be applied.
In said annexed drawings:

F1g. 16 is a plan viewE of the washer shown in Fi 15.
Fig. 11 o the drawing shows the portion of the gas generating apparatus to which my invention relates. In said figure is shown the carburetor chamber 1, partially filled with checker bricks, and provided with a gas passage 3 communicating with the gas generator. The top ofthe carburetor chamber 1 has a central o ening 4 communicating. with an upwar y extending casing 5 which communicates with the secondary blast conduit 6. Disposed centrally'of the casing 5 is the oil nozzle 7 which is supplied Awith oil an oil pi e 8.
In deliverin oil to a carburetor chamber it is desira le that the oil be delivered uniformly to al1 parts of the checker brick. The usual types of spray loz'zles adapted to discharge liquid in a uniform rain spray, however, cannot be used in carburetor chambers for the reason that their Vconstruction is such that they are quickly de stroyed by the intense heat to which they are` sub'ected; It is necessary that the parts o the nozzle be so constructed as to be free to expand and contract without distortion and without-setting up disru tive stresses therein. For this reason t e -type of spray nozzle which' has been most commonly used is one of the sin le orifice type in which the oil is discharge through an annular converging orifice 1n the form of a divergin conical stream commonly called an um rella spray. The nozzle which constitutes the present invention is designed to obtain a very uniform distribution of oil in a rain spray with a nozzle of the umbrella spray producing t section through l Aand a'dischargel head which will be shown in after described.
The nozzle discharge head comprises 4an outer casting 12 screwed upon the lower end of the body member. an inner nozzle head 13` secured within the casting 12, Vand a washer member 14 secured within the inner head 13. The inner nozzle head 13 has a peripheral, flange 15 fitting within the upper portion of the casting 12 and resting on an internal shoulder 16 therein. The flange 15 is of slightly greater diameter than the threaded lower end of the tubular body member 10 and is clamped between the shoulder 16 and the end of the tubular member 6 when the casting 12 is screwed onto said member. The inner head 13 has an internal shoulder 17 adapted to receive the peripheral flange 18 of the inner washer 14.
he flange 18 is retained against the shoulder 17 by means of split retaining ring 19 fitting in a peripheral groove inside the head 13. The casting 12 has a converging conical inner surface 20 below the shoulder 16 terminating in a restricted central passage 21 and a short conical discharge portion flaring outwardly from the passage 2l. The inner nozzle head 13 has a converging conical outer surface 23 below the flange 15 the same direction with yres which is concentric with the conical mner surface 20 of the casting 12 when secured]V therein.' The surfaces 20 and 23 form be tween them an annular outer dischargeorifice 24. The inner surface of the inner nozzle head 13 terminates below the internal shoulder 17 in a converging conical portion 25 similar to the inner surface 20- of the outer casting. The conical portion 25 ter minates in a central flared aperture 26. The inner washer 14 has a depending ste'm with a conical pointed end 27. When the washer 14 is secured within the inner nozzle head the conical point 27 is concentric with the inner conical surface 25 of the inner nozzle head 13 and forms therewith an inner annnlar discharge orifice 28. 4The peripheral flange 15 of the innerhead`13 is `provided with a series of passages 29 all slanting in ct to axial planes. The passage of the oi through the slanting passages 29 imparts a whirling mo- Y tion thereto. The peripheral flange 1.8 of
the inner washer 14 has similar slanting passages 30 preferably slanting in a direction opposite to that of the passage 29 (as clearly shown in Fig. 3) for imparting a whirling motionto the oil in passing through the inner annular orifice 28.
As indicated in Fig. 2am umbrella spray indicated by dotted lines 31 in said figure is discharged. from the outer annular orifice 24. A second umbrella spray indicated by the dotted lines 32 is discharged from theinncr annular orifice 28. The interference of the two'concentric sprays whirling in opposite directions breaks up the two whirling annular sprays into a rain spray which delivers oil quite uniformly to all parts oi the checker brick.
The passages 29 and 30 may be arranged to slant in the same direction as shownin Figs. 4 and 5. While the result produced in this case is greatly superior to a single umbrella spray the interference between the two sprays is not as great as where the sprays have a whirling motion in opposite directions and the distribution of oil is not as uniform.
In the nozzles heretofore used 'for discharging umbrella sprays, it has been nec.- essary to maintain an oil pressure of from 35 to 40 lbs. in spray. I have found thatthe double umbrella spray disclosed herein operates satisfactorily at a pressure as low as 15 lbs. as well as at the higher pressures. This makes it possible to control the rate of oil feed by varying thev pressure at which the-oil is delivered tothe nozzle making it unnecessary to provide adjustable parts in connection with thenozzle to vary the effective area` of the discharge orifice. This simplifies the constructlon ofthe nozzle and greatly lessens the liability' of the nozzle to get outof order v,duringoperation.v
InFigs. 12 to 16 in vlusive I have shown a modified form of nozzle in which means are provided for varying the effective area order to provide an efficient' of both the inner and outer annular orifices.
Under certain conditions, such as where an unusually large 'variation in the rate of oil flow is desiredy or where extremely exact regulation is required,-regulation of the discharge orifices may be desirable. In this modification the outer casing 33l has its upper end screwed into a T coupling 34 the stem 35 of which is threaded to receive the oil supply pipe. Upon the lower end vof the casing 33 1s screwed a casting 36 similar in all respects to the casting 12 shown in Fig. 1. Between the internal shoulder 37 of the castingv 36 and the lower end of the casing" 33 is clamped an annular washer 38 having slanting passages 39 formed by grooving the inner surface thereof. Slidably fitting within the washer 38 is an inner nozzle head 40 having inner and outer conical surfaces at its lower end similar to the inner and outer surfaces 23 and 25 of the inner head 13 shown in Fig. 1. The head 40 is provided at its upper end with internal screw threads to receive a sleeve 41. `The sleeve41 has upper and lower apertures 42 and 43 therein to Vpermit free passage of oil thereinto. The upper end of the ysleeve 41 passes through and has threaded engagement with a plug 44? screwed into the upper end of the T coupling v34. Above the plug 34 the sleeve 41 has a cap 45 screwed thereon and locked against rotation with respect thereto by a pin 46. The cap 45 carries a hand wheel 47 by means of which the sleeve 41 can be rotated for vertical adjustment to vary the area of the outer annular discharge orifice between the castlng 36 and head 40. Between an internal shoulder 48 inside the head `40 and the lower end of the sleeve 41 is clamped to a washer 49 having slanting passages 50 therethrough. Slidably fitting within the washer 49 is a pin 51 having a conical point 52 at its lower end. The upper end of the pin '51 has threaded engagement with Athe cap 45 and carries a hand wheel 53 at its upper end by means of which the pin 5l maybe adjusted vertically to vary the effective area ofthe inner discharge orifice. The operation of the adjustable nozzle shown in Figs. 12 to 16 is similar to that of the modification previously described. v
