HYDROCARBQN-BURNER SYSTEM.

Specification of Letters Patent.

Patented June 25, 1907.

To all whom it may concern:

Be it known that I, BENJAMIN F. J AGKSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain. new and useful Improvements in Hydrocarbon- Burner Systems; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accom anying drawings, forming part of this speci cation.

This invention relates to improvements in systems, or devices, for burning hydro carbon for heating urposes.

One object 0 the invention is to so construct -a hydro carbon burner and its mounting that it can be readily applied to an opening in the fire box of a boiler or furnace.

Another object of the invention is to so construct a hydro carbon burner that the atomizer thereof may be automatically cleared from time to time.

Anotherobject of the invention is to so construct a hydro carbon burner system that the supply of liquid fuel may be automatically controlled.

- Another object of the invention is to imrove the general construction of hydro car-' bon burners of the nature herein described.

The invention consists in such -peculiar features of construction and combination of,

parts as shall hereinafter be described and pointed out in the claims.

The drawing represents an elevation, partially in section, of the improved hydro carbon burner system as ap lied to a furnace, as the furnace or fire box 0 a steam boiler.

As shown in the drawings A represents a portion of the walls of any well known furnace, as the fire box of a steam boiler, 1n which it is desired to generate heat for any purpose; B re resenting an opemn in said wall, usually t e door opening, and a 'baflie plate, or block, designed to eflect the heat of the hydro carbon flame in any desired direction.

Adapted to fit in the opening B 1s a box of substantial construction and having the 1nclined wall 5, the top 6 and the bottom connected by sides as 8 this box being deslgnedto form a closure for the opening B, as shown in the drawings, and being furnished with lips as 9 and 10 which "prevent the box from being pushed too far within said open- :M. ,1 an. nlnqn Hus unnnn between the outer surfaces of the box and the edge of the opening B. Through an opening 1n the incllned wall 5 of said box extends the Bunsen tube 1 1 of the hydro carbon burner which is thereby supported in positionby said box. On the tube 1 1 is mounted the pressure chamber 12 furnished with the tubular compartment 13 having the openings -1414 and the lower end opening 15 and, within this com art-, ment 13 is located the atomizer tube 16 aving the contracted orifice end 17 ositioned in the o ening of the end 15 of saidbom artment, t e outer end of the atomizer -tu e 16 extendin through an openingin the wall of g the charm er 12 and being furnished with the casing 18. In this casing 18 is yieldin ly mounted a diaphragm 19 which prefera ly forms one wall of the liquid fuel conduit 20, so that sudden or undue pressure exerted on the fuel in said conduit will effect the deflection of said diaphragm in one direction. To this diaphragm 19 is secured the clearer needle 21 which extends through an opening in the casing 18 into the tube 16, the end of this needle be ng positioned close to and approximately in line with the orifice in the end 17, so that under the deflecting action of the diaphra m 19 a portion of the end of this needle may e projected sufficiently into said orifice to effect the clearin thereof of sediment or of forei n matter lo ed therein.

In or er that the c earer needle 21 may be manually actuated, the stem of the needle is continued through the diaphragm 19 to form the extension 23 which works in the stufiing box 24 of the conduit wall 22. The retraction of the needle 21 being effected by the spring 25 located between a portion of the casing 18 and the diaphragm 19 or, manually, by exerting a retracting strain on the extei sion 23.

Connecting the-conduit 22 with the atomizer tube 16 is the delivery tube 26 which communicates with the interior of the atomizer tube and is of a size suitable for the delivery of liquid fuel thereto. Communicating with the conduit 20 is the fluid fuel supply pipe 27 which is of any suitable length to connect a tank 28 or other source of fluid fuel sup 1y with said conduit. This pipe 27 is preferably furnished with a valve 29, or controlling the supply offluid fuel, and with the valve seat 30 ad acent to which is the diaphragm chamber-31 furnished-with the diaphragm 32 having the valve 33 whichis adapted to seat itself in the valve seat 30 when moved thereagainst by the deflection of the diaphragm 32.

The pressure pipe 34 is designed to be connected with any source of pressure such as air or steam, preferably the latter, and communicates with the pressure chamber 12 and with the upper portion of the tank 28, by the pipe 35, a connection also being made by the pipe 36 between such pressure pipe 34 and the diaphragm casing 31. The flow of the pressure fluid through the pipe 34 being controlled by the valve 37 located between the connection with the diaphragm' chamber 31 and the atomizer.

In order that foreign matter, may be excluded from the pipe 27 the end portion thereof within the tank 28 is preferably furnished with a strainer 38 of any usual construction.

It is of course evident that the pipes and conduits may be of any diameter, length and construction suitable for use in connection with devices of this character.

When working under normal conditions a suitable quantity of liquid fuel is forced from the tank by pressure from the pipe, and passes through the conduit 20 and is delivered by the tube. 26 to the interior of the atomizer tube 16 from whence it is drawn through the aperture end 17 by the flow of the pressure fluid through the pipe 34, the pressure chamber 12, through the openings 14 in the wall of the compartment 13 and thence out of the open end 15. The liquid fuel passing out of the atomizer tube being atomized and becoming mixed with the pressure medium passes through the Bunsen tube 11, drawing with it a proportion of air, which enters through the perforations in the outer portion of said tube, and is finally subjected to combustion within the furnace, the heat products of the. combustion of the gases being deflected in the desired direction by the baffle C.

Should the aperture of the atomizer tube become clogged, a back pressure of the fluid fuel will result and this pressure being exerted on the diaphragm 19 will cause the deflection of the diaphragm and the clearer needle 21 will be forced sufficiently into said aperture to clear the same, the pressure on the diaphragm 19 being then relieved, by the restarting of the flow of the fuel, the spring 25 will be permittedto act to move the diaphragm and its needle backward. This clearance may alsobe efl'ected manually from time to time by pressing against the extension 23.

Thedia hragm 32 is preferably'designed to resist eflection under ressure existing,

under normal use, in the pipe 3 1 but is also designed, to be deflected toward the valve seat 30 by undue increase of pressure in said pipe, as by an undue increase of steam pressure when the i e 34 is connected with the steam supply of t e boiler heated by this device, the result of this deflection of the diahragm 32 being to close the valve 33 against its seat 30 and prevent the flow of the fluid fuel a subsequent reduction of pressure in the pipe 34 permitting the diaphragm 32 to recover its normal position and open the valve for the passage of the fuel. When the valve 37 is closed the sudden increase of pressure in the pipe 34 will effect the deflection of the diaphragm 32 and the closing of the valve 33 against its seat, thus preventing the flow of fuel through the pipe 27 and the resultant waste thereof.

It is not my intention to limit myself to the construction herein shown, or to any particular construction, but only as herein claimed.

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

1. A burner comprising an atomizer tube having an apertured end, a casing mounted on said tube, a flexible diaphragm in said casing, a clearer needle movably mounted in the tube and designed to be actuated by said dia hragm, and a fluid fuel conduit, of which said diaphragm forms one wall, communicating with said tube.

2. The combination with an atomizer tube, a casing mounted thereon, a flexible diaphragm in said casing, and a clearer needle secured to said diaphragm and extending into said tube, of a fluid fuel conduit extending across said diaphragm and communicating with said tube, and an extension from said needle workin through an opening in the wall of said con uit.

3.
