" BUNSEN BURNER.
SPECIFICATION forming part of Letters Patent No. 781,454, datedJanuary 31, 1905.-
Application filed May 25, 1904. Serial No. 209,792.
v To all whom, it may concern:
Be-it known that we, TRUMAN G. PALMER,
residing at the city of Chicago, county of Cook, State of Illinois, and HARRY BARRIN- GER Cox, residing at Washington city, District of Columbia, citizens of the United States, have invented certain new and useful Improvements in Bunsen Burners; and we do hereby declare the following to be a full, clear, and
exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to certain improvestood by those skilled in the art in the light 'of the following explanation of the construction shown in the accompanying drawings, merely as an example for purposes of .illustration and description, from among other constructions and arrangements within the spirit and scope of the invention.
means in a Bunsen burner for attaining increased efiiciency at a reduced gas consumption by liberating, expanding, and fixing the gas fromthe service-pipe, thereby producing 3 a gas of the peculiar proper condition pre- I paratory to and for mixing with the air in the air and gas mixingv chamber to form a combustible mixture of the high efliciency desired.
The invention consists in certain-novel arrangements and combinations of parts, as more fully; andi'particularly described and pointed out hereinafter.
In the accompanying drawings,Figure l is a sectional perspective, showing-a form of Bunsen burner arranged in accordance with our invention. Fig. 2 is a cross-section on the line a; w, Fig. 1.
In the drawings, a is a nipple, tube, or tip in direct connection with the gas service-pipe and receiving the gas under service-pressure. The outlet from this pipe is approximately closed by any suitable means to provide one or more jet-openings or spray-orifices. For instance, the outlet end of the pipe is shown spanned by diaphragm 5, having one or more fine small jet-openings 0, so that the gas underservice-pressure is against the diaphragm. d is a tube removably slipped over or otherwise forming a tightjoint with tube aand' projecting above the same and carrying'or the air-inlet openings 71 above the diaphragm e. The tube g terminates at its upper end at the combustion-point or discharges through the reticulated diaphragm j to the combus:
tion-point above the same, according to the type of Bunsen burner employed.
The gas under service-pressure isforcibly i injected into chamber f inthe form of spray The object of the invention is to provide or jets and is suddenly liberated and expanded therein, creating eddies and currents and cansingia partial mechanical separation and thoroughcommingling and mixing of the molecules and a consequent peculiar preparation of the'gas, reducing the same, to a condition whichicauses the gas thus prepared to most efiiciently mix with the air in the chamber 71, under-thepeculiar requirements of a Bunsen burner. 'The expanded prepared, gas flows at a comparatively slow rate throughthe jet openingsororifices kof the upper diaphragm e and is thereby slowly sprayed or injected into the air and gas mixing chamber h, whereby the gas and air. are therein more thoroughly mixed-andcommingled to produce a combus tible mixture of a high efficiency for the purpose desired. By thus preparing the gas before it is admitted to the air and gas mixing chamber the proper proportions of air and gas can be more accurately maintained than has heretofore been possible and the objectionable excess of gas in the combustible mixture is avoided, and, furthermore, the gas is so prepared that when introduced into said a and gas mixing chamber a combustible mi:
- openings.
ture ofhigher efiiciency than heretofore is produced.
The location of the expansion or liberating chamber f between the gas-service pressure and the point of air-inrush into the mixingehamber maintains said chamber f comparatively cool and prevents superheating of the gas in the chamber.
To enable the chamber f to perform its peculiar function in causing the preparation of the service-gas preparatory to the mixture thereof with air in the air and gas mixing chamber 71., we jet the service-gas into chamber f through one or more inlets and then permit the prepared gas to slowly pass from chamberf into the air and gas mixing chamber in the form of one or more jets. We find it desirable to maintain the gas in chamber f under a reduced pressure, so that it will pass slowly into the air and gas mixing chamber, whereby we attain materially increased efficiency and a reduced gas consumption. The area or capacity of the service-gas inlet into chamber f is fixed whether such area be the aggregate of several jet-openings or of only one opening. The area or capacity of the prepared-gas outlet from chamber f is also fixed and is greater or of larger capacity than that of said service-gas inlet whether said enlarged outlet area is that of one outlet-opening or the aggregate area of several outlet- The essential feature is that the pressure in the chamber f is reduced below that of the servieegas, so that the prepared gas passes slowly through an outlet of fixed area into the air and gas mixing chamber,
: wherebyhighly efiieient combustible mixture is attained with a minimum consumption of gas. We 'find that this highly eflicient combustible mixture cannot be attained where the gas is discharged under high pressure or under the service-pressure into the air and gas mixing chamber even where regulatingvalves or other devices are employed to vary the quantity of gas admitted according to the servicepressure by varying the gas-passages. We prefer to employ gas inlets and outlets of fixed areas whatever the service-gas pressure, the areas of the inlet to and outlet from our liberating chamber being one greater than the other.
It is evident that various changes and modifications can be resorted to without departing from the spirit and scope of the invention BEST AVAILABLE COP described. Hence it is not desired to limit the invention to the exact construction shown.
hat we claim is 1. In a Bunsen burner, in combination, a pipe adapted to receive the gas under servicepressure and closed by a diaphragm having a reduced service-gas outlet of fixed area, a tube removably slipped on said pipe and closed by a diaphragm having a prepared-gas outlet of a fixed area which is greater than the area of said first-mentioned outlet, said tube forming an enlarged unobstructed gasliberating chamber between said diaphragms, and a Bunsen-burner tube extended up from said first-mentioned tube and having an air inlet above said last-mentioned diaphragm and forming the Bunsen-burner air and gas mixing chamber above said liberating-chamber, as and for the purposes substantially as described.
2. A Bunsen burner having an air and gas mixing chamber opening to the combustionpoint, combined with a service-gas-liberating chamber having a restricted inlet of a fixed area for injecting service-gas at service-pressure into said liberating-chamber, and an outlet of a fixed and greater area than said inlet for slowly discharging the prepared expanded gas at a reduced pressure into said air and gas mixing chamber, whereby an efficient mixture is attained in said airand gas mixing chamber, substantially as described.
3. In a Bunsen burner, in combination, a gas and air mixing chamber at one end communicating with the point of combustion for the combustible mixture and at the opposite portion having an air-inlet, and a service-gas liberating and preparing chamber having a restricted service-gas inlet and an outlet opening into the air-receiving end of said mixingchamber and through which the prepared expanded gas is injected at a reduced pressure into said mixing-chamber, whereby an efiicient combustible mixture is attained, said inlet and outlet being of difierent capacities and fixed areas.
In testimony whereof we affix oursignatures in presence of two witnesses.
