THOMAS J. LlTLE, JR., OF PHILADELPHIA, PENNSYLVANIA,
ATMOSPHERIC BURNER.
SPECFICATION forming part of Letters Patent No, 660,580, dated October 30, 1900.
Application filed January 6, 1900 Serial No. 611. (No mollet? To @ZZ whom t may concern,.-
Be it known that l, THOMAS J. LITLE, Jr.,
a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelpha and State of Pennsylvania, have invented certain new and useful improvements in Atmospheric Burners, of which the following is a speciiication.
My invention has relation to a burner in which a controllable quantity of air under pressure is presented and mixed with an illuminating-gas anterior-to its ignition and in which the gas is more thoroughly mixed with air, and the illuminating effect of the gas burned in the presence of a surrounding incandescing mantle is appreciably improved, with economy as to the quantity of gas used in the production of the derived appreciablyincreased illumination therefrom, and in such connection my invention relates to the particular construction or arrangement of the burner for the said purposes.
The nature and scope of my present invention Will be more fully understood from the following description, taken4 in connection with the accompanying drawings, forming part hereof, in which- Figure l is an elevational View of an atmospheric burner embodying the particular features of my present invention. Fig. 2 is a view, partly in elevation and partly in section, on the line c :n of Fig. l of the air-controlling valve-key for the burner-casting. Fig. 3 is a vertical central sectional view of the burner-casting, showing the internal arrangement thereof and the gas and air inlets to the expanding or mixing chamber of the device; and Fig. 4 is a perspective view of the mantle-suspending hook connected with the arch of the air-supply tubing of the burner.
Referring to the drawings, a, represents the J -shaped bu rner-casting,provided with anarrow gas-inlet at', leading from the threaded internal projection ft2 for fitting the gas supply or pipe.
l) is the air-inlet in the curved or crooked portion of the casting and provided with a tubing b', formed into a loop b2, and surrounding the burner proper and leading therefrom to a suitable source of air-supply under pressure. (Not shown.)
1n the curved or crooked lower portion of the J-sha'ped casting, in ontl wall of the same, is provided a threaded air-check valve-key c,
as illustrated in Figs. l and 2 of the draw,
ings, to control the quantitative supply and heating in the passage of the air through the tubing b into the interior of the lower portion of the J'shaped casting in respect to gas mixing therewith and to insure a more thorough admixture of the one with the other before reaching the expanding or mixing chant ber A of the casting aand prior to the ig' nition of the illuminating-gas beyond said chamber A at the cud of the Bunsen or other type of burner as, having a removable perfo rated surrounding cap a4. Through the volurne of air in respect to the quantity of gas introduced into the expanding or mixing chamber A being controlled through the key c a far more perfect mixture and superior quality of gas properly mixed with air is insured in the said chamber and for ignition in the presence of the suspended incandescing mantle d (illustrated in Fig. 1) and with thereby, as practice has demonstrated, a very appreciable increase in the illuminating effect derived therefrom. The mantle cl is suspended from a hook'e, formed or bent one or more times around the arched Aportion of the tubing b and fastened and held in a fixed position in connection with said tubing by means of a threaded jam-nut e', as clearly illustrated in Fig. fl of the drawings.
By forming the burner-castiug in substantially J shape and utilizing the crooked or curved portion as the air-inlet the tubing b may be readily attached to or removed from the casting without the use of elbows or joints, and when attached to the casting the tubing b is firmly supported thereby. This is advantageous for the reason that the tubing b forms the support for the fragile mantle d. The formation of a curved or crooked airin let l) is also advantageous in that the key or valve c for regulating the fiow of air may be located on the casting proper and not` upon the tubing b', which is less firm than the casting.
Having tlius described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is
An atmospheric burner, comprising a substantially J-shaped casting having a crooked IOT) or curved portion forming the inletl for air and a straight portion forming the inlet for gas, said straight portion havingr at its upper end an expanding portion, aJ tubing oonnected to and projecting upward from the crooked or curved portion and arching over the upper end of the straight portion of the casting, a mantle adapted to be supported by the arched portion of said tubing etude valve 1o or key located on ihe crooked or curved portion of thc casting and adapted to control the airinlet, substantially as and for the purposes described.
In testimony whereof have hereunto set my signmture in the presence of two subscribing witnesses.
