OIL-BURNER. 7

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed September 22, 1909. Serial No. 518,90a.

To all whom it may concern:

Be it known that I, Gnonon F. MOODY, a citizen of the United States, and a resident of Altoona, in the county of Blair and State of Pennsylvania, have invented a new and Improved Oil-Burner, of which the following is a full, clear, and exact description.

This invention relates to burners of a class in which fuel-oil and air are heated and mixed, forming a finely subdivided fuel that is burned for heating purposes; and has for its object to provide novel details of construction for an oil burner of the class indicated, which is highly effective as a means for welding metal parts together, is economical in the consumption of liquid fuel, affords a hydrocarbon vapor that issues from the burner in blue jets of flame, and is adapted for useful effect as a heating medium that may be utilized for difi'erent purposes.

The invention consists in the novel construction and combination of parts is hereinafter described, and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. 1

Figure 1 is a partly sectional plan view of the improvement; Fig. 2 is a side view of the same; and Fig. 3 is an enlarged transverse sectional view, taken substantially on the line 33 in Fig. 2.

In the drawings 5 indicates a mixing chamber, preferably cylindrical in form, that may be a metal tube of proper dimensions. An air jet-pipe 6, is held centrally and longitudinally within the mixing chamber 5, preferably by means of three clamping screw bolts 7, that are screwed through tapped perforations in the wall of the mixing chamber equally distant from each other, and near the extremity of the pipe that is within said chamber; and as shown in Fig. 1,

this end of the air pipe 6, terminates in a jet nozzle 0. Asupplementary air blast pipe 8 is held parallel with the pipe 6, near the normally lower side of the mixing chamber 5, by a plate metal. clamp 9, located near the rear end of the mixing chamber.

The air jet pipe 6, near its rear end, is bent at an angle toward the supplementary air blast pipe 8, and secured thereto by a T-fitting b, as best shown in Fig. 2., and from said fitting the air blast pipe 8 is extended to a source of air supply under proper pressure. In the pipes 6 and 8, valves 6 and 8 are respectively introduced, for control of the air forced therethrough. The remaining end of the supplementary air blast pipe 8 is extended in front of the mixing chamber 5, and may be bent so as to form an offset 0, therein, which will direct the air current passing therethrough in a proper direction for useful effect.

An oil feed pipe 10 is supported from the air jet pipe 6, and air blast pipe 8, by a clamp 11, that embraces these pipes, thus disposing the oil feed pipe above the air jet pipe at the rear portion of said oil feed pipe. At a suitable point forward of the clamp 11, the oil feed pipe is provided with two branch pipes 12, which extend laterally in opposite directions, as shown,in Fig. 1, and then forwardly parallel with each other, at opposite sides of the mixing chamber. The forward ends 12 of the branch oil pipes 12-, are extended toward each other at a right angle, through the wall of the mixing chamber 5, and their inner ends 0, e, terminate in like jetnozzles that are spaced apart opposite each other. The jet nozzle a that is on the forward extremity of the air pipe 6, is disposed near to and between the jet nozzles c, c.

The rear end of the oil feed pipe 10 is extended toward and connected with an oil supply under pressure, and in said pipe near the valves 6 8 a valve 10 is introduced which serves to graduate the feed of the oil for spraying from the jet nozzles c, e.

While the improved oil burner may be employed as a heating medium for different purposes, its preferred use is for welding joints on a frame for a locomotive engine while in place thereon. To this end, a temporary inclosing wall is built around the portion of the frame which is to be welded, and the heating device is supported thereat, in proper position for directing a blast of flame directly upon the exposed joint that is to be welded. The spraying jets of oil that are now projected toward each other from the nozzles e, e, are met by a forcible air j at issuing from the nozzle a.

The mixed currents of atomized oil and atmospheric air flow from the forward end of the mixing chamber 5, and when ignited burn fiercely with a blue flame, and as a further supply of air may be found advantageous, for blending with the air and oil jets, a plurality of perforations g are formed in the mixing chamber near said jets. The forward portion of the supplementary air blast pipe 8 is so relatively positioned, that the current of air issuing therefrom will be adapted for directing the flame at the front end of the mixing chamber, into contact with the material to be welded, and thus control the welding operation.

It is found in practical operation of the improved heating device, that there is a great economy effected in the consumption of fuel oil, that a moderate air pressure is sufficient for highly effective service, and that a perfect Weld is produced in a comparatively rapid manner.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

1. An oil burner comprising a mixing chamber, an air supply pipe at one end of the chamber and extending along below the same and having an upwardly offset portion at the opposite end of the chamber, said pipe having a branch extending into the chamber, a fuel supply pipe adjacent the air supply pipe, said pipe branching adjacent to the chamber, the branches extending alongside the chamber, and each having a lateral nozzle extending into the chambe at right angles to the inner branch of the air supply pipe and having the inner ends adjacent thereto, means for supporting the air pipe in the chamber, clamps connecting the fuel supply pipe with the air supply pipe and valves controlling the said pipes.

2. An oil burner comprising a mixing chamber, an air supply pipe at one end of the chamber and extending along below the same and having an upwardly ofl set portion at the opposite end of the chamber, said pipe having a branch extending into the chamber, and a fuel supply pipe adjacent the air supply pipe, said pipe branching adjacent to the chamber, the branches extending along side the chamber, and each having a lateral nozzle extending into the chamber at right angles to the inner branch of the air supply pipe and having the inner ends adjacent thereto.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
