BUNSEN TUBE FOR INCANDESCENT LIGHTfH EA I ING, OR COOKING APPARATUS.
SPECIFICATION formingpart ofIJetters Patent N 0. 729,298, dated May 26, 1903. Application filed October 7, 1901. Serial No. 77,887. (No model- To aiZ whom it may concern: Be it known that 1, CHARLES PHILIPP EH- MANN, merchant, a subject of the King of Great Britain, and a resident of 43 Black friars street, Manchester, England, have in-- vented certain new and useful Improvements in Bunsen Tubes for Incandescent Light,
Heating, or Cooking Apparatus, of which'the following is a specification.
In the hitherto known and employed Bun w sen tubes for incandescent burners and cooking apparatus the gas entering from the nozzle flows freely through the Bunsen tube and invention consisting in inserting within the Bunsen tube a resistance by means of which; in the gas and air current various whirlsor' spiral paths are produced,whereby an intense and thorough mixing of the gas and air, and thus a complete combustion of the gas mixture, is attained. The complete combustion is, furthermore, supported by the beforemen tioned inserted resistance inthe Bunsen tube,
as the same consists of a good heat-conducting material, so that it becomesintensely hot and effects a preliminary warming of thegas mixture. I In the accompanying drawings some constructions for carrying the invention into effeet are shown, in which- Y Figure 1 illustrates the employment of the improved device for incandescent-light burners, the view showing a longitudinal section through the burner. Fig. 2 represents a Bunsen tube for cooking or heating purposes in longitudinal section, in which a resistance correspondingto that of Fig. 1 is inserted.
Referring to Fig. 1, in the Bunsen tube 0 upon the gas-nozzle b-a coiled spiral wire consisting, preferably, of copper is so inserted as to rest or bear upon the said noz zle b. The gas coming out of the latter, as'well as the air introduced through the holes f, strikes against the resistance d and receives the beforementioned whirl or spiral path which causes a thorough mixing of the gas and air. The prepared gas mixture passes then in known manner through the burner-crown g of the burner a to the outside of the burner, where the same is completely ignited and consumed. In consequence of the combustion, however, both the burner a and thus, also, the wire spiral (1 become heated at the same'time and give up their heat to the gas mixture flowing through same,and thus warm the latter.
For the burners of heating and cooking apparatus, Fig. 2, the screw-shaped coiled wire d, serving as the resistance, is employed, the
sa-mebeing inserted in the Bunsen tube 0 and placed upon the nozzle in exactly the same manner as described in reference to the inoandescent gas-burner of Fig. 1. Also in this construction by means of the heated burnercrown g the copper wire (1 becomes heated,
and consequ-ently,also,the gas mixture heated or warmed.
When employing this device for cooking and heating apparatus, the further advantage is attained that in consequence of the complete combustion of the gas mixture the formation of badly-smelling vapors is avoided and the providing of special tubes to carry away such vapors thus rendered unnecessary. Having'thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
The combination with the burner-tube having an enlarged chamber atone end, said chamber being provided with air-holes, and a gas nozzle extending into said enlarged chamber, of a resistance-comprising an immovable spirally-wound metallic wire seated upon the gas-nozzle, extending the full length of said tube and impinging the walls of the narrowest portion of said tube to-reeei-ve heat therefrom. f
In witness whereof I'll-3N6 hereunto set my hand in presence of two witnesses.
