VALDEMAB F. LSSOE, OF BROOKLYN, NEW YORK..

OIL-BURNER.

Specification of Letters Patent.

Application tiled December 16, 1908. Serial No. 467,741.

fatented May 10, 1910.

To all whom-it may concern:

Be it known that I, VALDEMAB F. LssoE, a citizen of the United States, and a resident of the borough of Brooklyn, in the county of Kings and State o New York,

- have invented certain new and useful Imrovements in Oil-Burners, of which the allowing is a specification.

This invention relates to oil burners, and its or anization comprises means for spraying nel, oil and the like into a mixing chamber and sub-dividing it in said chamber by a. multiple series of transversely-acting ture is deliver-e nected thereto that do not come in the path' currents of a spraying medium such as steam or air under ressure. The said currents enhance the division of the. oil into a fine s ray, and tablish the intimate mixing of t c oil andlspra ing medium before the inixfrom the burner.

The invention is characterized' by means for at ali times maintaining operative, the a purtenanccs that control the quantities of tlie fuel and the spraying medium which are to be mixed, irrespective of the effects of expansion and contraction to which the burner is subjected, by virtue of changes of tem rature.

T e objects of the invention are secured. by locating the operative means for changing the discharge capacities .of the fuel and the spraying medium outlets in close proximity to said outlets, so that changes of temperature will not interfere with the adjustments of said outlets and their etiieient operation. The said operative means are further characterized by having parts conof any stops und the like, which would 4hinder their operation when subjected to changes of length and form by changes of temperature, due to the spraying medium or the furnace for which the burner is pro.

vided.

The burner is further characterized by u fuel or oil strainer which is 4directly con nected to the burner, and by the disconnection of which means are obtained for its easy cleaning, as well as for the cleaning of the burner. c

Referring to 'the drawings, Figure 1 shows a top plan Viewr of a burner exemplifyinff the invention, Fig. 2 represents a parta vertical section or Fig. 1- on the line 2, 2, Fig. 3 represents a fra nentary ortion o f the right hand end of (Fig. 2 wilt some o f theparts shown in full, Fig. 4 is a side elevation of Fig. 1, Figs. 5, 6, 7 and 8 show sections of Fig. 2 respectively on the lines 5 5, 6 6, 7-7 and 8-8, Fig. 9 represents nected with u boiler with natural draft, Fig.4

13 is a left hand front view of Fig. l2, Fig. 14 represents the burner with a boiler having forced draft appurtenances, Fig. l5 shows.

a front elevation of a water tube boiler with a number of the burners connected thereto and Fig. 16 represents a partial section of Fig. 15 on the line 16, 16.

llie burner is shown with a body comprising respectively the outer and inner cylindrical steam or air tubes and 3l. The tube 30 is supported by a bushin 32 having the flange 33 with-the-openings or the bolts 34. A dial plate 35 with the scale 36 and elongated openings37 is located adjacent to the outer face of the flange 33. The inner face of said tiange bears a inst the front 38 of a furnace with whic the burner is connected; and the bolts 34 clamp the dial 35, the fiange 33 and the front 38 of the furnace together. A pointer for the scale 36 is fastened to the outer tube 3f) and carries the operating handle 46. On the inner 4tube 31. The ring 48 also constitutes the bottoni of a stutling box between the said outer and inner tubes of the burner. A gland 49 bears against the packing 5G, and a screw cap 51 is provided for said atutiin bo'x. A drain cock 57 is connected with t e tube 30- 'lhe outer end of the tube lOris threaded at 52 to sup )ort thc spraying head to be described, an adjacent to said threads is formed an inner collar 53 having openings 54, and the large threads 55 of very course pitch that support the threads 56 formed on the outer surface of tho oil barrel 58. The barrel 58 .it its rear end is threaded at 78 for the oil pi e or conduit 59, and ut its front end is threa ed for the oil nozzle 60. The nozzle 60 is iluted on its outer cylindrical surface as shown at 61, and has formed The spraying head comprises the ring .Q EEST AVinLABLE Copy 957,614

The oil chamber 83 has formed at. its rear end a neck 95, which is threaded on its outer cylindrical surface for a cap 96, and the latter fornis therewith a stuffing box havingr the packing 9T; From the lower portion of thc oil chamber S3 extends the oil strainer chamber 100 which is lthreaded at the lower portion thereof for the foot 101 ot' an oil Strainer, a washer 102 bein'r interposed bef tween the edge of the cham er 10|) and the foot. 101.

A barrel 103 with perforations lOl eX- tends up from the foot 101. Inletbai-rela` 105, 106 are formed with the chamber tot). in the former of which is shown a plug 107 and in the latter the piping 10S with the union 109, and vulve 110, for the introduction of the oil to he used in the burner.

A yalve rod 114 with hand wheel ll is.
