OIL BURNER Filed Aug. 29 1928 Fi /(f. 1
FqfHQ INVENTOR c7- cI-Hasltizz ATTORNEY Patented Sept. 29, 1931 JOSEPH J. HASKIN, OF STOCK'IQN, CALIFORNIA OIL BURNER.
Substitutefor application serial No. 51,943, filed August 24, 1925. This application filed August 29, 1928.
' Serial No. 302,765.
This invention relatesto improvements in oil burners and especially to a type particularly intended for firing locomotive and similar steam boilers, and represents certain features of improvement over my Patent No. 1,029,927 dated June 18th, 1912, being also a substitute application for my application Serial No. 51,943, filed August 24, 1925.
The principal objects of the present invention are to simplify the construction of the burner so that it is easier and cheaper to manufacture; to increase the efficiency thereof by the rearrangement of certain parts; to provide for a more thorough heating of the oil as it initially enters the burner; to provide for the fuel spray being positively thrown in a horizontal direction from the burner so that it enters the fire box in the desired and proper direction; and to construct the shell of the burner so that while it may be made fairly light, no danger is had of the same being warped or frac- W tured by the clamps used to secure the burner in place.
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.
These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.
In the drawings similar characters of reference indicate corresponding parts-in the several views:
Fig. 1 is a longitudinal section of the burner.
Fig. 2 is a cross section on the line 22 of Fig. 1.
Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes one side wall of the burner, formed integral with which is a top wall 2, a bottom Wall '3 and intermediate walls 4 and 5. All said walls'are parallel in a transverse plane and are also parallel in a longitudinal plane for the greater portion of their length. The space between the walls 2 and 4 forms an oil chamber 6; the
space between thewalls'4 and 5 form a hot air chamber 7; while, the space between the walls 5 and 3 forms a steam chamber 8. The forward end of the upper wall 2 slopes abruptly down toward the wall 3 as at 9, and terminates in vertically spaced relation to said wall 3 to form a rectangular and transversely extending nozzle 10.
The wall 5 terminates at short distance inwardly of the nozzle and the sloping wall 9 and makes a closure with the wall 3 as shown at 11. except for a narrow transverse slit 12 which extends the full width of the walls.
I have found from long experience and experimentations with the revious burner that with a nozzle height 0 of an inch, which is a standard size, the horizontal center line of the slit 12 should be exactly of an inch below the horizontal center line of said nozzle. This relative location between the two openings is absolutely essential to insure that the oil spray projected through the nozzle by the force of the steam blast" issuing through the slit, shall go straight ahead into the fire box asis necessary. 4
If. the slit is any higher the spray will be deflected downwardly; and if the slit is lower the spray will be deflected upwardly. In the manufacture of the shell, the casting from which the same is made is cast without the slit. The latter is then formed by sawing through the metal closure 11 from the edges of the transverse walls opposite the wall 1 This is a very simplefoperation to perform and insures that the slit will have the desired smoothness of surface, and will also be the proper height throughout. The integral construction of the transverse andside walls insures thenozzle slit'being always maintained in exactly the propor location when once out, without the pos-- sibility of any deflection dueto warpage or 5 expansion as was the case with the previous device.-
The wall 4 terminates a short distance rearwardly of the wall 9, so as to leave an oil passage therebetween, said termination being also a certain distance rearwardly of the forward end of the wall 5.
At its rear end the wall 4- slopes upwardly toward the top wall 2 in spaced relation to the rear wall 13 of the shell. The wall 2 at this point projects upwardly above its normal plane so as to form a transverse chamber 14 which is substantially the same diameter as the oil pipe 15 which is screwed into the side wall 1, in alinement with said chamber 14.
The rear end of the wall also slopes up somewhat as shown in Fig. 1. A hot air pipe 17 is connected to the rear wall 13, and is located centrally of the width thereof. The center line of said pipe is somewhat above the lowersurface of the major straight portion of the wall 4, while its lower edge is about on a level with the top of the slope of the wall 5.
This pipe 17 extends from said rear wall under and forwardly of the burner to a point adjacent the rear end of the fire box 16. An opening 19 is provided in the latter in alinement with said pipe so that hot gases from the interior will be drawn into the pipe with the operation of the burner. The nozzle is also located so as to project slightly into the fire box through an opening 20 therein. A steam pipe 21, taking its supply from the boiler, is connected to the rear wall 13 of the burner shell centrally of the width thereof, so as to discharge evenly into the steam chamber 8.
As before stated the walls 1 to 5, and 13 are formed as an integral casting, the outer ends of said walls lying in a common plane parallel to the wall 1 and being unconnected along their outer edges.
1 therefore provide a cover plate 22, similar to the wall 1, except that there is no opening therein in alinement with the pipe 15. This cover is adapted to abut against and be secured to. the outer edges of the various walls by the necessary number of screws 23 to make the different chambers tight.
This form of construction is very easy to manufacture. and is better than making the entire device of a one-piece casting, since the use of intricate core work is avoided, and all interior surfaces can easily be in .pected for blow holes and other defects before placing the cover plate 22. T 0 provide a good bearingsurface for the plate against the outer walls, I form outwardly projecting flanges 2st along the top and bottom of the same. Flanges 25 corresponding to the flanges 2l similarly project from the wall 1.
The plate 22 is the same height as the side wall 1 plus the flanges 25, and the top and bottom edges of said plate and flanges 25 are horizontally alined and together form the engaging surfaces for the clamping bars 26 used to maintain the burner in place. Said bars when clamped about the burner therefore will not en age the relatively thin and easily deflected walls 2 and 3 but continuous vertical thicknesses of metal, so that said walls are not subject to any pressure tendin to strain and fracture them.
Owing to the location of the pipe 17 relative to the adjacent surface of the wall 3, the hot air entering the chamber 7 through said pipe is instantly directed against said wall. This will cause the oil flowing through the chamber 1a to be initially heated to degree which will aid in its ready atomizing.
The steam pipe 21 tapping the chamber 8 at the center of its width insures the formation of an even spray of steam through the slit 12, and consequently causes an even flow of the fuel spray to be projected through the nozzle 10.
The upward slope of the wall 5 at its rear end prevents any oil which may rest on said wall from flowing into the pipe 17 when the engine is travelling on an upgrade, and the burner consequently has a downward slope toward its rear end.
From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.
lVhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.
Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:
In combination, an oil burner comprising a substantially horizontal shell having longitudinally extending flanges projecting above and below the top and bottom surfaces of the shell at the opposite side edges of the same, and clamping bars adapted to extend across the burner and rest on the flanges.
In testimony whereof I afiix my signature.
JOSEPH J. HASKIN.
