OIL-BURNER AND ATOMIZER-SLOT ADJUSTMENT.

Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed April 7, 1917. Serial No. 160,452.

To all whom it may concern:

Be it known that we, GEORGE B. VON" Boom: and ED IN F. INoLEs, citizens of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burners and Atomizer- Slot Adjustments, of which the following is a specification.

This invention relates to improvements in oil burners of that class which is employed in conjunction with boiler and like furnaces for fuel purposes.

It consists of a structure forming a conduit having superposed passages, one of which conveys the fuel and one steam, comprcssed air, gas, or other vapor, to be used in spraying or spreading the fuel and supplying oxygen to the fire, and, in'conjunction with this apparatus, of ameans for mounting it with relation to the furnace within which it is to operate:

It also comprises a means for adjusting the atomizer slot through which the steam is admitted to be mingled with. the oil, and in details of construction which will be more fully explained by reference to the accompanying drawings, in Wl1lCl1-- Figure l is a longitudinal, vertical section of the burner on line 1-1 of Fig. 2.

Fig. 2 is an end view, looking to the right.

Fig. 3 is a vertical, transverse section on line 3-3 of Fig. 1.

Fig. 4c is a partiahvertical,longitudinal section of a modification, showing the ato mizer slot adjustment.

Fig, 5 is a diagrammatic view, showing the application of the device to a boiler furnace.

In the prior art a form of burncr'has been described, in which the oil is supplied to through a substantially horizontal passage and be delivered at the end, and below this passage is a steam passage, through which jets of steam are discharged to meet the oil which flows downward upon the steam jet, and a transversely corrugated 'table is disposed in front of these discharges over which the jet of steam and oil is discharged and delivered in the form of a fine spray or vapor into the furnace, where it is to be utilized. Constant change in the size and type of locomotive boiler furnaces to which this apparatus is especially adapted, necessitates some means by which to properly fix the burner with relation to the furnace.

In the present construction, A is an in tegral structure containing the upper oil passage 2 and the lower steam passage 3, the discharge end of the oil passage being curved downward in such a manner as to deliver the oil upon an elongated jet of steam which is discharged outwardly in such a manner as to receive the descending oil and convert it into a line spray or vapor which flows over a table 7, preferably having a transversely corrugated surface and side walls or guards to confine the spread of the discharged vapor. The side walls or guards for confining the spray are integral with the burner body, extending therefrom on the opposite sides of the table so that in adjustment said table will move.

vertically between the walls.

In order to properly adjust the slot through which the steam is discharged, there is employed a movable part, over which the steam jet is discharged, and this may be raised or depressed to change the size and relative position of the jet. In Figs. 1 and 3 this adjustment consists of a plate 5 which is fitted into a vertical slot and which is so adjusted in the slot as to leave a narrow jet space through which the steam is discharged horizontally over the table 7. This plate is movable in .the slotin which it fits and may be raisedor lowered and secured by means of bolts passing through bolt holes 8 in the lower part of the plate and securing it to the lowerpart of the burner structure, as shown.

In Fig. 4 we have hown the horizontally corrugated plate 7 as having its lower part perforated or slotted as in- Fig. 1 to receive bolts which pass through this plate and allow it to be raised or lowered to form the necessary slot for the discharge of steam. In this casetlle plate 7 is movable upon a vertical face or provided on the depending wall, said face being set inwardly from the end of the diaphragm or partition 10 so that the angle plate '7 will have its angle, or the rear edge of its corrugated table, opposing the under face of said partition, and by raising and lowering this plate 7 the size of the passage may be readily varied until it is in the position for most effective work, being then secured by means of bolts, as previously described. The plate 5 may also be and both may be ently adjustable, said table being movable between theside walls that extend out from the burner body, as shown in Fig. 1.

In order to properly adjust and fix the burner with relation to a furnace," a flange 11 is cast upon the exterior of the body A, projecting transversely therefrom and havin bolt holes 12 made in it through which b ts may be passed to secure the burner in oil con duithaving a its desired position. A position in which this burner may be roperly securedv is to the lower front endof the fire pan which may be illustrated, as at 13, and to which the burner is bolted, so that a jet therefrom will be discharged toward the interior area ofthe furnace where it is diverged and directed to pass through the boiler hues. With this manner of mounting, it will be manifest that the burner may be readily moved or replaced, so that the combined oil and steam spray may be so directed within the furnace as to be most effective. v c

Having thus described our invention, what we claim and desire to secure by Letters -Patent 15- '1. An atomizer and burner including an oil conduit having a'downwardly discharging forward end, asubjaoent steam conduit having a discharge passage beneath the oil discharge, the steam conduit hdsving a vertical wall depending from the forward edge of the bottom Wall to provide a front face, and means adjustably secured to the front face of the vertical wall for movement to vary the size of the steam passage, the upper edge of said means being roughened.

2. An atomizer. and burner including an downwardly dischargfor confining 1,2ee,e11

ing forward end, a subjacent steam conduit having a discharge passage beneath the oil discharge, the steam conduit having a vertical wall depending from the forward edge of the bottom wallto provide a front face set inwardly from the discharge end of the oil conduit,- and to the depending wall and provided with a corrugated upper face over which the steam and oil are discharged.

3. An oil burner including a steam con duit having a horizontal outlet, a superposed oil assage with a discharge above the steam out ct adapted to deliver the oil downwardly upon the passing jet of steam, a table extending horizontally outward. below the steam jet, and having a corrugated upper surface, and means for adjustably securing the table to vary the size of said steam jet.

An atomizer and burner including an oil conduit having a downwardly discharging forward end, a subjaccnt steam conduit having a discharge passage beneath the oil discharge, the steam conduit having a vertical wall depending from the forward edge of the bottom wall to provide a front face set inwardly from the discharge end of the oil conduit, a table adjustably secured to thedepending wall and provided with a corru gated upper face over which the steam and oil are discharged, and side upstanding walls the discharged fluids. In testimony whereof we have hereunto set our-hands in the presence of two subscribing witnesses. 1 Q
