Patented Nov. 7, 1939 I UNITED s'r'rss This invention relates to oil burners and particularly to an improved burner which maybe used in steam producing boilers on steamships,
and elsewhere, an object beingto provide a con-- struction which is simple and very efiective to secure a desired whirling spray.
Another object of the invention is to provide an oil burner for boilers and the like, wherein means are provided to produce a whirling spray ,without any moving parts and with a minimum path for thexpassage of oil from the supply pipe to the nozzle opening.
- An additional object is to provide an oil burner formed of a minimum number of parts wherein the structure is so formed that the part carrying the nozzle opening may be varied'and the remaining parts adjusted to vary the flow of oil according to the size of the nozzle opening.
In the accompanying drawing Fig. 1 is a vertical sectional View through an oil burner disclosing an embodiment of the invention, the section beingtaken along line 1-! of Fig. 6;
Fig. 2 is a top plan view of the structure shown in Fig. 1;

Fig. 9 is a view similar to Fig. 1 but showing a modified form of the invention;
Fig. 10 is a view similar to Fig. 9 but showing a nozzle block in a different position.
Referring to the accompanying drawing by numerals, I indicates an oil supply pipe which may supply oil under desired pressure from any suitable source. Connected to this pipe is the burner which consists principally of a burner body 2 and a nozzle nut 3. From an examination of Fig. 1 and also of Fig. 9, it will be seen that the complete burner is made from a minimum number of parts. In Fig. 1 there are shown three parts while in Fig. 9 there will be three parts when the burner is complete by the addition of a nozzle nut 3.
The body 2 is provided with a square or hexagonal end 4, whereby it may be readily secured on to pipe I. Extending forwardly from the part' t is an exteriorly threaded portion 5 on which the interiorly threaded clamping nut 3 is screwed until the surface or shoulder 6 presses against the surface l3 of block 62 5 In the form of the invention shown in Fig. 1, a separate oil-deflecting cap 1 is forced into the end of the threaded section 5 until the upper surface of cap i is flush with the upper end of section 5. Cap 1 is really a round disk pressed 0" I into the position shown in Fig. 1 and held therein by friction. This cap is provided with four tangentially and diagonally arranged passageways or apertures 3 which are preferably disposed at an angle of approximately twenty degrees with a plane perpendicular to the axis of the burner, as shown in Fig. 6.
As the oil under pressure from pipe 1 is forced against the inner surface of cap 1, some ofthe oil will pass through the various passageways or jet openings 3 in different directions, whereby the oil is cause to whirl in the whirling chamber 9. From this chamber the oil in a whirling state is projected outwardly through the nozzle opens ing it. The distance which the sprayed oil will travel depends upon the pressure used. However, as the oil moves away from the opening I0, it will whirl and move in a substantially cone shape as it burns so that there will be little or no loss.
By the-arrangement just described, as shown in v 3011 Fig. 1, it will be observed that there is ample space for the oil except in the passageways 8 and opening'lii where the oil is restricted. As these passageways are very short, the burner will function for long periods of time without requiring cleaning. Each of the passageways 8 is of the same size or slightly larger than the opening IB, whereby an appreciable pressure will be produced in the whirling chamber 9 before the oil passes out the opening it in a fine spray.
As illustrated particularly inFigs. '7 and 8, the block I2 may be changed from time to time as" desired so as to vary the opening 10. When the 7 structure is arranged as shown in Fig. '7, the
aperture I 0 is central of the nut 3 as well as central of the block l2 and the passage in the burner member 2. When the nut 3 is screwed down tight the surface 6 will press against the surface or shoulder l3 and clamp the lower surface of the block l2 against the shoulder I3 whether the whirling chamber 9 is large or small. As shown in Fig. 7, the whirling chamber is large,
while in Fig. 8 it is small, but in both instances the outlet' I0 is central of the block.
As illustrated in Fig. 9, an oil-deflecting block I is made integral with the section 5. Aside from this detail the construction is identical with that shown in Fig. 1 and is adapted to receive a block I 2 and clamping nut 3 of the type shown in Fig. 1. When using the construction shown in Fig. 9 with the block l2 and shown in Fig. 5, only three parts are used and these three parts make up the complete burner.
By providing a structure formed of few parts and constructed with very short passageways, the burner will not need cleaning except after long use, and when a cleaning operation is desired it may be quickly done as easy access is secured to all the passageways after the nozzle has been unscrewed. It is understood, of course, that the entire burner could be made of various sizes and used for various purposes without departing from the spirit of the invention.
I claim:
1. An oil burner of the character described including a burner body having an oil inlet at one end and a plurality of oil outlets at the opposite end, said outlets comprising a plurality 36 of diagonal tangentially arranged passageways at an angle of approximately twenty degrees with a plane perpendicular to the axis of the burner with the discharge ends of the passageways ar ranged in a circle spaced from a central point,
:a nozzle block arranged against the end of said burner body, said nozzle block having a central outlet and an uninterrupted open whirling mixing chamber having a, flat topand a fiat bottom, said top and bottom being arranged parallel,
:said nozzle block having a shoulder surrounding the same and positioned to overlap somewhat the outlet end of said passageways, said block having an outlet opening which is proportional to the size of the whirling and mixing chamber and the position of said shoulder being arranged so that the outlet opening is of given size and said shoulder overlaps and closes a certain proportion of the discharge ends of said passageways, and means for clamping said nozzle block in functioning position.
2.
