IRVING CORSER, OF

VAPORIZING To all whom it may concern:

Be it known that I, IRVING Consnn, citizen of the United States, residing at Portland, in the county of Multnomah and State of ()regon, have invented certain new and useful Improvements in vaporizing Oil-Burners, of which the following is a specification.

My invention relates to apparatus for burning crude oil, and particularly to a construction in which the oil is vaporized and mixed with air prior to its combustion.

The objects of my invention are to provide a burner and vaporizer of great simplicity and in which the parts are made detachable from each other so that all the parts of the burner may be kept clean.

Another object of the invention is to provide a vaporizer of a simple form which, however, will not burn out, and in which the oil will travel back and forth a number of times prior to being mixed with air and passing to the burner.

The invention further contemplates the forming of the vaporizer with an oil passage or passages of relatively small dimensions so that in case the vaporizer should burn out at any point, the amount of oil issuing from that point would be relatively small, and thus only a small flame would be produced, thus preventing the chance of accident due to the burning out of large pipes, and the consequent flooding of the stove with burning oil.

My invention also consists in certain details of construction and arrangement of parts as stated in the following specification and particularly set forth in the claims appended. i

For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a fragmentary section of a stove, showing my improved burner in place therein; Fig. 2 is a fragmentary horizontal section on the line 22 of Fig. 1; Fig. 3 is a fragmentary section on the line 33 of Fig. 1; Fig. 4 is a longitudinal section of the vaporizing grid; Fig. 5 is a transverse section on the line 5-5 of Fig. 4; Fig. 6 is a transverse section on the line 6-6 of Fig. 4; Fig. 7 is a perspective view of the vaporizing grid detached from the remainder of the mechanism; and, Fig. 8 is a detail. fragmentary section of the supporting plate, the mix- Specification of Letters Patent.

ing pipe being shown in elevation, the section illustrating a modified manner of supporting the mixing pipe upon the supporting plate.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to these figures, A designates a stove and B the grate thereof.

2 designates the base plate of the burner which is preferably cast with the upwardly extending side plate 8, this side plate being slotted, as at 4, in order to act as a support for one end of the vaporizing grid. The upper surface of the base plate 2 is formed with the shallow depression 5 constituting a receptacle for priming. The exact form of this receptacle is of course nonessential to the operation of the invention.

Supported in one end of the slot 4 and at the other end upon the standard 7 which extends upward from the upper face of the plate 2 is the vaporizing grid 8. This grid is cast in one piece and comprises a plurality of parallel barrels 9, each formed with the upper and lower channels or bores 10. These barrels are connected by the transverse webs 11. The ends of the bores 10 are closed by the screw-threaded plugs 12. The channels in each of the barrels are connected at their inner ends by the vertically extending bores 13, while at their outer ends the lower bore of the first barrel is connected by a transverse bore 14 to the lower bore of the second barrel, while the upper bore of the second barrel is connected to the upper bore of the athird or last barrel bv the transverse bore 15. These bores 14: and 15 are closed at their outer ends by means of screw plugs 16. A supply pipe 17 is connected to the uppermost bore of one of the outer barrels 9, and the pipe 18 is connected to the lowermost bore of the other outer barrel and extends upward and enters an opening in the side plate 3. It is here provided with a nozzle 20.

Mounted upon the side plate 3 and extending in therefrom above the grid 8 is the mixing pipe 21 which terminates in any suitable outlet 22. The outer end of the mixing pipe is detachably supported upon the side plate 3 and is also provided with the air inlet openings 23 on the sides thereof. As shown, the outer end of the mixing pipe is provided with the laterally extending placed guide flanges 2% on the plate 3, The plate at is provided with a bolt passing through the plate 3, whereby the mixing pipe is supported in position. It will be obvious that the vapor passing up the pipe 18 will enter the pipe 21 and that it will act to draw air into the openings 23, and that this will be mixed with vapor so as to provide a proper mixture for combustion. The mixed air and fuel vapor will then pass along the pipe 21 and be discharged at the outlet 22 where it will be burned. The flame issuing from the burner 22 will keep the vaporizer hot so thatv the oil passing therealong will be thoroughly vaporized before it passes into the tube 21. It will be seen that the vaporizing grid is so constructed that the liquid fuel is carried in a circuitous course through the grid, longitudinally along each tube, and then back to the entrance end of the tube again, and thence to the tube adjoining. Because of the relatively small bores and the relatively thick walls of the grid, the grid will retain heat, thus adding to its vaporizing qualities. Furthermore, it will be thoroughly and uniformly heated, by reason of the thickness of the walls and also by reason of the fact that the barrels are joined by transverse webs which act to conduct the heat from one barrel to the other and to thoroughly and uniformly distribute the heat. Furthermore, these transverse webs'provide a series of passages by which the heat may pass down and around each of the barrels. The vapo-rizing grid constructed as described is extremely strong and therefore will be amply able to resist the pressure of the vapor, and will not readily burn out.

lVhile I may use any means desired for supporting the vaporizing grid 8, I preferably provide the standard 7 with an opening 25 and rovide one of the bores of the grid with a screw pin 26 instead of a plug, which screw in projects through the opening 25. This, while supporting the inner end of the grid,permits the grid to be easily detached and drawnfrom the slot 4. It will also be obvious that the mixing tube 21 may be easily detached to ermit it and the nozzle 20 to be cleaned, while the detachability of the vaporizing grid 8 permits it to be easily removed and cleaned by removing the screw plugs closing the ends of'the bores.

The fuel pipe 17 is connected to any suitable supply pipe and provided with regulating valves. Preferably, this supply pipe is provided with a main valve 27 and also with a starting valve 28 which controls the passage of fuel to a small pipe 29 which extends through and is supported on the side plate 3 and which discharges fuel into the pan or receptacle 5. One of the chief clangers in oil stoves is the danger of leaving the starting valve open so that oil is continually immediately close, thus shutting ofi the flow 'of oilto the pipe 29.

The principal advantages of my invention reside in the fact that the oil is thoroughly fvaporized before being mixed with air and before passing to the burner, and that this EVELPOI'IZlDg takes place in a cast iron grid of iextremely solid formation, through which the oil is passed along six different channels. The bores of this grid are only a quarter of an inch in diameter, and hence, there is a relatively small amount of oil at any time ,Wlthlll the grid, this oil, however, passing ithrough rapidly and being rapidly vaporized as needed. Hence, if by any chance the grid :should become burned out or crack so that leakage would occur, the opening through which oil or vapor will pass is relatively small, and no flooding of the stove can occur,

nor will there be any chance of explosion. {The burning out of vaporizers constructed Zas ordinarily, is one of the main elements of danger in the use of stoves of this character. EBy my construction, I have minimized and practically obviated all danger of this accident occurring.

The various parts of my burner are so Econnected that they may be easily taken apart so that the interior of the grid may be thoroughly cleaned and so that the interior of the mixing pipe may also be thoroughly cleaned, as well as the burner. There is thus no chance of soot or other products of combustionbein'g deposited upon the inner surface of the pipes and bores and acting as a nonconductor of the heat.

My invention is simple, may be applied to ;any ordinary stove, and has been found thoroughly effective in practice.
