OIL BURNER.

Application filed Ju1 a1,

Brooklyn, res ectively, in the counties of Lebanon and l ings, respectively, and States of Pennsylvania and New York, respectively, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

The invention relates to oil burning apparatus in which the oil is atomized, for example, by low pressure air and discharged for ignition in a highly atomized state thru a suitable tip.

It has for its object aburne'r having means for more efiiciently atomizing the oil and mixing the same with a gaseous medium, more particularly in two stages; and to afford, also, a burner of simple and durable construction in which the flame isadjustable thru movement of the said tip; and wherein, furthermore, the oil supplying nozzle is conveniently removable for cleaning and so constructed as to be readily cleaned.

The nature of the invention, however, will best be understood when described in connection with the accompanying drawings, in which- Fig. 1 is an elevation of the burner.

Fig. 2 is a plan thereof.

-Fi'g. 3 is a longitudinal section burner.

Fig. 4 is a fragmentary section of the sleeve for introducing the atomizing medium.

Similar characters of reference designate I corresponding parts throughout the several views.

Referring to the drawings, the burner i shown to consist of a suitable casing havin a vertically disposed chamber 10 through which the atomizing gaseous m'edium,as air under the requisite pressure, is to be sup plied, the volume of same being controllable by a suitable valve as the butterfly valve 11 provided therein. The upper portion of the casing comprises a body 12 afi'ording a hori-- zontally disposed chamber which is o n to the vertical-chamber 10 and is provide with thru the.

an inlet 13 and outlet 14 axially disposed therein. Fitting coaxially within the body. 12 is a sleeve or tubular member 15 having openings 16 to afford communication with the chamber12 and thru which the gaseous 1923-; Serial No. 654,839.

atomizing medium may enter. Thissleeve is secured to the inlet 13 and its forward end projects beyond the outlet 14:, terminat- 4 111g in a constricted and flarin An intermediate portion of the s eeve is also constricted, as at 18, to formfla Venturi nozzle in conjunction with the oil supply nozzle 20 which is mounted coaxially within said sleeve, the nozzle having an axial bore 21 extending from endto-end and provided with radial outlets22 at the Venturi end. The air velocity is consequently increased 'at this point, its at'omizing efl'ect enhanced and an intimate mixture therewith of the oil supplied thru the radial outlets 22 is secured. The bore of the nozzle is closed atthis end preferably by api-pe plug 23; and, similarly, the opposite end of the bore is closed by a pipe plug 24 fitting in the head 25 of the nozzle. The head 25 serves also to seal the inlet 13 of the body 12 and [is provided with a duct 26 communicating with the bore 21, the former having suita le means "for outside connection to supply oil to the nozzle. By this expedient, the nozzle with head is conveniently removable; and by unscrewing the

plugs

23 and 24 from the ends thereof, the bore is open thruout and ma readily be cleaned when this becomes necessary.

Surrounding theforwardend of the sleeve 15 and havinga sliding fit with a portion of the same and with the body portion 12 to close substantially the outlet 14 of the latter, is an adjustable tip 30, tubular in form and having an opening 31 at its outer end coaxial. with the flaring outlet 17, the

wall of the tip and the outer end of the sleeve being separated and forming a tapering annular'space between the same. The tip, moreover, is provided with openings 32 to afi'ord communication between the inteintimate mixture of oil and airproduced is.

outlet 17.

' rior of the body'portion and the said tapercarried forward by the air delivered thru the annular space to the outlet 31 of the tip where it is further atomized and mixed and discharged for ignition with a blowing effeet, the swirling motion heretofore referred sleeve an the outlet 14 of the body portion. To effect this reciprocation of the tip, a yoke 35 is arranged over the burner appa'ratus with its arms at either side thereof,

and the ends of said arms are secured to the tip 30 at diametrically opposed points. Thru an opening 36 in the back of the'yoke is inserted a stud 37 which is threaded into the head 25 of the oil nozzle, said stud carrying a collar 38 within the yoke; and at its outer end a hand wheel 39 is adapted to shoulder against the back of the yoke. so that in turning the said hand wheel, the yoke is correspondingly advanced or retracted to adjust the tip 30. In order to limit the extent of the reciprocation, the arms of the yoke are provided with open notches or slots 40 in the upper edges there of and into which fit corresponding pins 41 secured in the body portion 12, the same acting as stops thru engagement with the respective sides of the notches.

We claim 1. An oilburner, comprising a casing provided with an inlet for a gaseous medium, a sleeve longitudinally arranged therein and in, communication with the interior of the casing, said sleeve having an axial outlet and a constricted intermediate portion, the portions of the sleeve immediately in advance and succeeding said constricted portion flaring in opposite directions, an oil supply nozzle mounted coaxially therein and having radial outlets in proximity to the constricted intermediate vportion of the sleeve.
