Patented Aug. 18, 1931 UNETED STATES HUGH W. CHRISTIE, OF TULSA, OKLAHOMA GAS BURNER Application filed May 10,

This invention relates to burners of the type employing a series of plurality of burner jets which are all connected to a source of gas supply.

The primary object of this invention is to provide a device of the above mentioned character, having an auxiliary pipe extension for accomplishing more complete carburation of the burning fluid or gas.

A still further object of this invention, is to provide a device of the above mentioned character, which is detachable from the main gas supply pipe and which is supported thereon by means of an extension secured to the gas supply pipe which is received 1n one of the carburating pipes of the burner nozzle.

A still further object of this invention, is to provide a device of the above mentioned character in which two gas carburating tubes are connected to two gas burner jets in a normal manner in order that the flames emanating from the jets will be offset from the main gas supply pipe thereby aiiording a greater heating area than if the burners were in single longitudinal alignment with the main gas supply pipe.

lVith the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists inthe novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the accompanying drawings wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a top elevational view of: the burner showing the relation of the auxiliary carburating device connected to the burner jets;

Figure 2 is a side elevation of the invention further showing the arrangement of the carburating pipes secured to the burner nozzle;

Figure 3 is a side elevational view of the invention showing the manner of supporting the carburating tube and the auxiliary carburating tube upon the main gas supply P 1 1929. Serial No. 362,088.

Figure 4 is a cross-sectional view taken on lines l4l of Figure 2 and showing the manner in which the auxiliary carburating tube is connected to the main gas supply pipe and to the burner jet;

Figure 5 is an end elevational View e1nbodying the invention partly in cross-section showing the burner assembled in relation to the main-supply gas pipe;

Figure 6 is a similar view partly in cross section taken on line 66 of Figure 2 showing the relation of the gas burner supply pipe and its nozzle to the auxiliary carburating tube;

Figure 7 is a cross-sectional view taken on line 77 of Figure 2 showing the means for clamping the carburating tube and burner nozzle to the main gas supply pipe; and

Figure'8 is a cross sectional view taken on line 88 of Figure Qfurther showing the clamping device or means for holding the carburating tubes upon the main gas supply pipe and also showing the air vent. in the auxiliary carburating tube.

Referring more in detail to the accompanying drawings which shows the preferred embodiment of the invention, there is illustrated a main gas supply pipe 5, which may be of any desired length upon which is secured or formed bosses 6 and 6 for receiving burner nozzles orjets 7 and 7'. It will be noted that the bosses 6 are smaller in diameter than the bosses 6 which are formed in a manner for the purpose of receiving the main carburating tube and the auxiliary carburating tube which will be later described.

The main carburating tube 8 is provided with a plurality of air openings 9 for ad mitting air to the gas jets 7 whereby a mixture is carburated and formed for passage to the burner jets 10. The burner jets 10 are set forth in Patent 1,67 9,298 and are described in more detail therein. The lower end of the main carburating tube 8 is secured to themain gas supply pipe 5 by a machine screw 11 which engages the boss 6 and holds the carburating tube 8 securely in place. The auxiliary carburating tube 12 which forms the most important part of this invention, 100

is also similar to the carburating tube 8 and is provided with openings for the passage of air 13, for commingling with the gas emanating through the pipe or jet 7 The auxiliary carburating tube 12 is merely suspended above the boss 6 and is provided at its upper end with an extension 14 which has its end communicatively secured to the upper portion of the main carburating tube 8 which is the termination thereof and also to the central portion of the pipe 15 which con nects the burner jets 10.

It may be stated that the gas jets 7 and 7 are screwed into the main gas supply pipe 5 and are provided with the usual openings at the upper end thereof designated by the reference characters 16 and 16.

It is to be understood that any number of the burners including the main carburating tubes 8 and the auxiliary tubes 12 may be secured to a main gas supply pipe 5 if desired and which is usually the custom in connection with this type of heating devices.

As shown in the drawings, the main gas supply pipe 5 is screw threaded as at 17 to receive gas pipe fittings to a gas main or the like, while the opposite end is shown 7 closed as at 18, it may be opened and extended to any desired length upon which the bosses 6 and 6 and the gas jets 7 and 7 may be secured.

It has been found in common practice by providing an auxiliary gas jet with an auxiliary carburating tube mounted thereover communicating with a similar carburating tube and gas jet, that better results are obtained and a better carburating mixture is formed for burning in the burning jets.

It is to be understood, that variations in size and arrangement of the carburating tube may be resorted to without departing from the spirit of the invention or the scope of the sulojoined claims.

I claim I 1. In a gas burner of the character described, a main gas supply pipe, spaced gas nipples secured to the main gas supply pipe,

a gas burner supported over the nipples, said gas burner including a main and auxiliary operating tube having their ends surrounding the nipples at the junction with the pipe.

2. A gas burner comprising a pipe having aboss, spaced nipples communicating with the interior of the pipe one of them being located upon the boss, a tubular member snugly receiving the boss and having openings at the upper portion of the nipple thereon, a second tubular member surrounding the other nipple and having openings, tubular members being connected together at their upper ends and the first mentioned tubular member having a pair of spaced outlet nozzles located at its upper ends. 7

In testimony whereof I affix my signature.

HUGH W. CHRISTIE.
