OIL BURNER.

APPLICATION FI'LED FEB. 24, 1914.

Patented June 29, 1915.

JOHN n5 oowienza, F BAYONNE, NEW JERSEY.

iii-Q8 16.

Ta all whom it may concern:

(L Be it known that I, JOHN B. COWPER, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in OiLBurners, of which 1 the following is a specification.

The present invention has for its most important object the provision of an oil burner of inexpensive, simple and durable construction, whereby the oil is emitted-in the form of a mist or funnel shaped spray composed of completely atomized and highly inflammable oil, without mixing it within the burner with air, steam or'like fluid under pressure. In accordance with this stated purpose of the invention I have provided an oil burner having an outlet and channels through which the oil flows. to the outlet, the said channels being. arranged to direct the oil to the outlet in separate streams or jets which are at an angle to each other and which impinge upon the outer corner of the outlet,-the cross sectional area of said outlet being less than the combined areas of the channels at the delivery ends of the latter, whereby the jets are broken up or deflected by the outlet at the moment of emission. It will be understood that by this definite correlation of oil channels and outlet there is no well or space behind the outlet which receives the oil and interferes with the effectiveness of its motion.

In other words it is a definite purpose of my invention to avoid the discharge of the oil from the channelsinto a well or space behind-the outlet wherein it may have sufii-- fits resulting from the particular correlation of outlet and oil channels herein stated may be see red in a-most practicable Way, I have devised a burner which is further characterized by the utmost simplicity of construction, the accessibility of the partsand the ease with which the parts may be assembled and removed.

OIL-BURNER.

itsscope-as defined-by the subjoinedclaims.

Fig. 3 is a sectional viewof the s ra 'ng block; Fig. 4 is'an elevation of said b ock. Fig. 5 is a view looking at the forward end of the same; Fig. 6 is an enlarged fragmen- Patented June 29, 1915 Application med February 24, 1914. Serial No. 820,491.

parting from the spiritof the invention or tary sectional view intended particularly to show that the jets impinge upon the outer corner of the outlet; Fig. 7 is a rear end view of the burner with the parts assembled; and Fig. 8 is a detail perspective view of a keywhich may be employed to apply or re-v move the holding nut.

The particular burnerherein illustrated embodies three members, to wit, a shell .or body A,- a spraying block B and a holding nut O. The body or shell A is suitably formed for attachment to the part through which the liquid to be sprayed is supplied, being herein shown as provided with threads 10 for securing it to the endof a pipe or tube (not shown) having communication 11 and a rear cylindrical section 12, the diam- '90 chamber having a forward conical section,

eter of the cylindrical. section being less than the diameter of the threaded part 13 of the shell or body.

The spraying block conforms in diameter and external shape to the chamber in "the v a forward wall of the shell or body A, hav- .-ing a forward conicalpart 14 and a rear cylindrical part 15 which respectively fit the conical section 11 and cylindrical section 12 of said chamber. The cylindrical part 15 of the spray block preferably protrudes from the rear end of the cylindrical part 11 of the chamber and is engaged by the holding nut C. The latter is externally threaded to. engage the threads 10 of the shell or body A and is provided with an an lar' opening 16 adaptedto receive a key by which it may be inserted or removed. a

The spraying block B has an internal Fig. 5.

16 in the holding nut 0, one of the functions of said opening 16 being to permit the passage of the liquid to said block. The external surfaceof the conical part 14 of said block has a plurality of grooves forming channels 18, 19 and 20, three such channels being preferred. These channels extend longitudinally of the block and in a slightly spiral direction thereonand their delivery ends are slightly offset from each other at the forward end of the conical section, which latter is slightly flattened, as shown best in These channels receive the liquid at their rear ends, through inlet openings 21, 22 and.23 extending-from the chamber 17 in the block, each channel having its individual inlet opening, as shown.

2-1 designates an outlet opening, formed in the forward wall of the shell or body A at the apex of the conical part 11 of the chamber in said wall. This outlet opening is in the form of a shallow approximately cylindrical chamber. The chamber is made shallow so that its relative diameter bears such relation to its length that the formation of a well behind the outer end of-the outlet openand highly inflammable.

The device is particularly adapted to be used as an oil burner because of the thoroughness with. which it will atomize oil and supply the same in a most highly inflammable condition without requiring the oil to be mixed with air, steam or the like, but it is not my purpose to restrict its use to an oil burner as it may be usefully employed whenever thorough atomization of a liquid is desired.

The internal chamber 17 of the spraying bloclr B is preferably provided with screw threads, as shown'at 25, in order that it may be mounted on a mandrel to be turned in a lathe and in order, further, that it may be conveniently removed for cleaning, an appropriate tool engaging such threads obviously being employed to effect such removal.

Having now described the invention What I believe to be new and desire to secure by Letters-Patent, is V '1. A device of the character set forth comprising a body having a shallow approximately cylindrical chamber forming an outlet opening and means within said body arranged to direct a plurality of jets toward said outlet opening, the outlet opening and means for directing the jets being relatively so arranged that the jets will impinge substantially upon the outer edge of the outlet opening and said outlet opening being of lesser cross-sectional area at its outer end than that of the combined jets.

2. A device of the character set forth comprising a body having a shallow approximately cylindrical chamber forming an outlet opening, a conoidal spraying block arranged in said body and having a plurality of external liquidconducting channels arranged to direct the liquid in a plurality of separate jets substantally against the outer edge of the outlet opening, said outlet opening being of lesser cross-sectional area at its outer end than the combined cross sectional areas of the jets.

3. A device of the character set forth comprising a body having an internal chamber the forward portion of which is"substan tially conical and the rear portion of which is substantially cylindrical, said body also having a shallow approximately cylindrical chamber forming an outlet opening which enters its said chamber at the apex of the conical portion of the latter, and a spraying bloekfitted to said chamber, the said block comprising a substantially conical portion and a substantially cylindrical portion, the substantially conical portion of the block being formed with external approximately let opening in the body.

4. A device of the character set forth comprising a body having a substantially conical chamber and provided with a shallow approximately cylindrical chamber forming an outlet opening which enters said chamber at the apex of the latter, a spraying block fitted to said chamber and a holding nut mounted in the body and engaging the rear end of the spraying block, said spraying block having, a substantially conical section provided with liquid conducting substantially spiral narrow channels arranged to direct the liquid in a plurality of jets substantially against the outer edge of the outlet opening in the body, said outlet opening being of lesser cross-sectional area at its outer end than the combined cross sectional areas of the jets.

5. A device of the character set forth comprising a body having a substantially conical chamber and provided with a-shallow approximately cylindrical chamber forming an outlet opening which enters said chamber at the apex of the latter, a spraying block fitted to said chamber and a holding nut mounted in the body and engaging the rear end of the spraying block, said spraying block having a substantially conical section provided withexternal liquid conducting substantially spiral channels of uniform cross section throughout and an internal rearwardly'open chamber provided with lateral openings to said chamber, and said holding nut'havin'g an opening which registers With the chamber in the spraying block and through which the liquid is supplied to the latter, the channels on the exterior of the block being arranged to direct the liquid in a plurality of iets substantially against the outer edge of the outlet opening in the block, and said outlet opening being of lesser cross-sectional area at its outer end than the combined cross sectional areas of the jets.

. 6. A device of the character set forth comprising a body having a thickened forward wall provided with a chamber the forward portion of which is substantially conical and nally threaded portion rearward of its forward wall and its said wall formed with an outlet opening which enters the chamber at the apex of the conical portion of the latter; a spraying block fitted to said chamber, the said block comprising a substantially conical portion and a substantially cylindrical portion, the substantially conical portion of the block being formed with external approximately spiral channels and the substantially cylindrical part of the spraying block having an internal chamber which communicates with said channels, said channels being so arranged asto direct the jets substantially against the outer edge of the outlet opening in the forward wall of the body and said outlet opening being of lesser cross sectional area than the combined cross sectional areas of the channels; and an extornally threaded holding nut which i s re ceived' by the threaded portion of the body and engages the rear end of the spraying block and has an opening registering with the chamber in the latter.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
