OIL BURNER Original Filed May 2 1921 improved Patented Oct. 20, 1931 UNITED STATES PATENT OFFICE ALBERT E. GRANT, OF NEW Y RK, N. Y., ASSIGNOR T0 CALOROIL BURNER CORPORA- TION, A CORPORATION OF DELANARE OIL BURNER Original application filed May 2, 1921, Serial No. 466,183.
1927. Serial This invention relates to oil burners and particularly to the nozzle devices of such burners, the general object of the invention being to provide nozzle devices of a new and construction and arrangement whereby they are rendered clean and free of and having an oil passage 45.
oil automatically.
To the above and other ends which will hereinafter appear, the invention consists in features of construction, combinations of devices, and arrangements of parts hereinafter described and particularly pointed out in the appended claims.
The invention will be described in detail 1-: in connection with the accompanying drawings wherein Fig. 1 is an elevation of the nozzle device; Fig. 2 plan view thereof; Fig. 3 is a longitudinal vertical sectional view and Fig. 4 an end elevation looking from the left in Fig. 1.
The present case is a division of my prior application, Serial No. 466,183, filed May 2,
1921, which has eventuated in Patent 1,632,402
1: be employed; and it is also a matter of choice whether the fuel supply means supplies fuel by gravity or pumps it under pressure or otherwise maintains it at a constant level to be aspirated.
The flame-forming nozzle herein shown comprises essentially a steam nozzle such as 23 having a passage 43 directed for instance horizontally and an oil pipe 44 inclined preferably about 45 in the direction of the jet The end of the oil pipe 44 is positioned in the path of the steam jet and is slightly inclined clownward with relation to the axis of this jet so that the passage opens in the direction of the jet. The edge 46 of the oil pipe 44 is Divided and this application filed May 14, No. 191,337.
preferably made thin with the surrounding surfaces rounded off slightly as by rubbing with emery in order to prevent the edge from being split by the impinging steam or other fluid as would be the tendency if the edge were left sharp as cut. The rear point 50 of the edge 46 is slightly higher than the front point or lip 51, as indicated by the angle a in Fig. 1 wherein the deflection of the top edge toward the left has been exaggerated for the sake of clearness. The steam jet striking along the back surface 52 is deflected upward and outward sweeping around the edge 46 on smooth lines and merging finally with the other jet lines. The result is not only the creation of a vacuum but a drawing of the steam particles along the edge 46 keeping it clean and free from any ac cumulation of thickened oil. The point 50 is preferably positioned in the jet above the center line of the opening 43 and for the structure shown in the drawings it has been found that the most efiicient action is obtained with point 51 at a distance of nearly one third of the radius of passage 43 above the center. v
The distance between the nozzle 23 and oil pipe 44 along the axis of the jet will depend upon the particular results desired and upon the steam pressure and the size of the orifice 43. In'the example shown in the drawings the point 50 is spaced from the end of the nozzle about three times the diameter of the nozzle passage 43. In the flame forming nozzle of this invention the diameter of the oil duct or passage 45 is very large and the oil is sucked therethrough from a lower constant level so that a constant resistance is imposed on the oil feed due to the distance the oil has to be raised to reach the edge 46. In the nozzle 23 with a steam orifice 43 of one eighth of an inch and relatively low steam pressure of less than twenty pounds per square inch the oil passage 45 may be one quarter of an inch in diameter. This large oil passage and high suction and direct action of the steam on the edge 46 provide a flame forming nozzle that not only efliciently draws up and vaporizes and mixes theoil but also avoids all stoppage or stufiing of the oil pasice sages. The steam stream surrounds the oil which does not come into contact with the air until at some distance from the nozzle so that the flame never approaches the oil in liquid ionm and the temperature of the oil passage at the edge 6 is constantly tint of the steam.
Relative adjustment of the steam and oil passages may be provided as bv nuts 65 threaded on the nozzle stem 66 and by wormwheel nut 67 threaded on the stem 68 of the oil pipe. The threaded stem 68 passes freely upward through an opening indicated at 6862 in Fig. 3 which is of greater diameter than the stem itself so that up-and-down movements under control of the worm wheel 67 are not interfered with. The worm wheel 67 is burned by worm 69 on rod 7 O and this adjustment automatically locks the parts at each setting. All the parts may be mounted in a single frame 71.
It will he understood that the source of oil suppiy has its level considerably below the 'top of the nozzle 44 so that normally F? the level of the oil in the nozzie is below the top and after operation will always drop back to the normal level.
It wiil be observed that the present invention there is provided a highly efficient- J? nozzle device, the parts of which are readily ad'ustahle to obtain the best. results.
arions changes may be made without .departing from the spirit and scope of the inventaon.
.3 I claim:
1. in an oil burner 'the combination with a jet forming orifice, of means for supplying oil :to said jet comprising a tube inclined in the direction of said jet and having its end out diagonally with relation to the axis of said tube and in a plane coinciding approx-imateiy with thedi-rection of the axis of said orifice and inclined slightly forward with relation thereto, so that said oil tube opens 0 away from said orifice and in the direction of said jet, and the jet striking against the back surface of said tube and deflecting upword and outward sweeps around "the edges of the oil tube opening on smooth lines to draw the jet particles along said edge and prevent dripping of the oil therefrom.
2. In an oil burner the combination with a jet forming orifice, of means for supplying oil to said jet comprising a tube inclined in the direction of said jet and having its end out diagonally with relation to .the axis :of said tube and in a plane coinciding approximately with the direction of the axis of said orifice and inclined slightly forward with relation thereto, so that said oil tube opens away from said orifice and in the direction of said jet, and the jet striking against the hack surface of said tube and deflecting upward and outward sweeps around the edges of the oil tithe openingon smooth lines to draw the jet particles along said edge and prevent dripping of the oil therefrom, said oil tube being adjustable with relation to said orifice by rectilinear movement at right angles to the axis of said orifice so that the end of the oil as my be moved directly across the jet Without changing its angular relation thereto.
3. In an oil burner the combination with a jet tanning orifice, of means for supplying oil to said et comprising a thin wall tube ex tending upward into said jet and having its upper discharge end in substantially the p we of the axis of said jet and formed as an elongated opening of greater length than width and with its longer axis extending in tihe direction of said jet, so that the jet sweeps around the edges of the oil tube opening on smooth lines to draw .the jet particles along said edge and prevent dripping of the oil theaefrom, said oil tube being adjustable at right angles to the axis of said jet. so that the end of the tube is movable along rectilinear lines across said jet in front of said orifice.
