CLOYD C. MOWILLIAMS AND JOSEPH MILLER, 01? SCHENECTADY, NEW YORK.
To all whom it may concern:
Be it known that we, CLoYn G. MCWIL- LIAMS and JOSEPH MILLER, citizens of the United States, residing at Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.
Our invention has reference to an oil burner in which a liquid, usually in the form of a hydro-carbon, is finely sprayed and thoroughly mixed with a as such as air or steam before it comes wit in the region of combustion.
For a fuller understanding of our invention, reference is had to the accompanying drawings, in which- Figure 1 is a central longitudinal section of the burner except the plug through which the fuel enters the burner which section is taken on the line cd of Fig. 4, the pipes which conduct the fuel to the burner being shown in elevation; Fig. 2 is a side elevation of the head which closes the inner end of the casing of the burner; Figs. 3 and 4 are end elevations of the same; Fig. 5 is a central longitudinal section of the head; Fig. 6 is a cross section of the same; Fig. 7 is a longitudinal sectional view on the line c-d of Fig. 4; Fig. 8 is a longitudinal section of the casing for the burner and Fig. 9 is an end elevation of the, same; Fig. 10 is a side elevation of the shaft upon which the turbine and mixer are mounted and Figs.'-11 and 12 are end elevations thereof; Figs. 13 and 14 are side and end elevations respectively of the turbine; Fig. 15 is a detail view of the washer located between the turbine and its bearings; Fig. 16 is a detail view of.
the mixer; Figs. 17 and 18 are detail views of the spring which bears against the hub of the mixer and of the pin which prevents rotation between the mixer and the shaft on which it is mounted respectively; and Fig. '19 is a detail view of the screw which socures the mixer to its shaft.
The'hurner comprises in general a casing A within which is received the head B through which the constituent elements of the fuel, such as oil and air enter the burner and from which they are directed against a rotary member G here shown as a turbine, which is, in turn, connected to a mixer 1). Suitable pipes 1 and 2 carry the constituent elements of the fuel such as oil and air, the flow of which. to the burner is controlled by Specification of Letters Patent.

' valves 1 and 2 in the pipes 1 and 2 respectively. These pipes are joined at 3 from which point the oil and air pass through a common pipe 4, which pipe may be screwed into the head B of the burner at 5 (see Fig. 5). This head is rovided with a chamber 6 where the oil and air entering the burner are received. The end of the head B opposite the pipe 4 is provided'with openings 7 which lead from the chamber 6 to the inner endof the head and are somewhat spirally arranged and are contracted into nozzles at their outer ends so that the air and oil which enter the burner under pressure, on emerging from the opening 7 are directed at an angle against the buckets of the turbine C so as to impart a rotary movement thereto.
The casing as best shown in Fig. 8. The center of this spider is elongated at 9 to form a bearing for a shaft 10 upon the inner end of which, adjacent to the spider 8, the turbine C is secured. A washer 26 is disposed between the turbine C and the bearing for the shaft on which the turbine is mounted. The outer end of the casing A is contracted so that a limited passage 11 is provided between this outer end of the casing and the corresponding end of the shaft 10. The outer end of the shaft 10 carries a diffuser D which comprises a series of blades 12 set obliquely to the shaft 10 on the hub 13. The portion of the hub adjacent the blades is beveled at 14, the extreme outer. end of the casing A being correspondingly beveled at 15, as clearly shown in Fi 1. The outer end of the shaft 10 upon which the diffuser D is secured is made smaller at 16 than the rest of the shaft so that a shoulder '17 is provided thereon. The inner end of a coil spring 18 which surrounds the shaft engages the shoulder 17 while the outer end engages the hub 13 of the diffuser. The diffuser D is prevented from turning on its shaft by a key 19 (see Fig. 18) which engages a groove in the end 16 of the shaft and a corresponding groove in the bore of the hub of the mixer. mixer is kept in engagement with the sprin 18 by means of a screw 20 which is receive in the outer end of the shaft. The screw is provided with a lug 21 which is received within one of several openings 22 in the mixer and prevents movement of the screw relative to the mixer and the shaft. It will be obvious that by this means the annular opening between the beveled ends of the Patented Mar. 11, 1913.
A is provided with a spider 8 casing A and the hub of the mixer can be nicely adjusted,
The outer end .of the burner is: provided with a hood 23 secured to the casing A by a set screw 24. The .end of the hub immediately surroundingfthelcasing A is pro vided with openings 25.' While we have shown our burner provided'wi'th ahood it will be understood, 'that'ifor certain purposes, such as the heating of boilers, the hood may be dispeusedwith. The operation of ourburner is as follows :-Oil and air under pressure are carried in the pipes 1 and 2 and admitted to theburner through the pipe 4. They then enter the chamber of the plug B from which they pass through the openings 7 and are directed atan angle against the buckets of the turbine 0, producing a rotary movement of the turbine and of the shaft 10 to which it is secured and at the same time partially mixing the oil and air. The mixture then passes on through the burner and is directed outwardly by the hub of the diffuser against the blades 12 of the mixer which are rapidly rotated by the turbine and which thoroughly spray the oil and complete the mixture of the same with the air or steam. The hood 23 confines the flame to the'region where it is desired that cornbnstion-.-.shou ld take place and the-openings 25 m the base of the hood admit air which prevents the flame from hanging in the base of the burner.
While in accordance with the patent statutes we have shown the preferred form of our invention, it is to be understood that numerous changes could be made therein without departing from the spirit thereof.
What we claim as new and desire to secure by Letters Patent of the United States, 1s,
1.111 an oil burner, a casing, a head adapted to close one end of the casing and having a chamber and inclined passages leading inward therefrom, means for conducting fluid fuel to said chamber, a turbine mounted within said casing adjacent the inner end of said head, and a' mixer comprising a series of blades connected to and revoluble with said turbine.
