WILLIAM II. GRAY, OF ST. LOUIS, MISSOURI.
IMPROVEMENT IN LAM P-BURNERS.
Specilication forming part of Letters Patent No. 113,876, dated April 18, 1871.
To all whom 'it may concern:
Beit known that I, WILLIAM H. GRAY, of the city and county of St. Louis, and State of Missouri, h ave invented a certain Improvement in Lam p-Burners; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing, making part of this specification, in which- Figure l is an elevation of the burner. Fig. 2 is a vertical section in a plane parallel to the at side of the wick-tube. Fig. 3 is a vertical section in a plane at' right angles to the one shown in Fig. 2.
The sameletters of reference are employed in all the figures in the designa-tion of identical parts. f
Thisinvention consists in an improvementupon a lamp-burner for which Letters Patent were granted to George Lupton on the 13th day of December, 1870, andthe novel feature consists in extending thev contracted end of the lower dome to the top of the wick-tube, so
as to form a narrow air-space around the 1at ter, through which the upward currents of -cold Lair, entering through the foraminous base of the dome, pass to the flame, and, impinging against the wick-tube, keep it at such a low temperature that all danger vof setting` fire to the contents of the fountain or bowl by the overheating of the wick-tube is removed.
To enable those skilled in the art to `make I and use my invention, Iwill proceed to describe its construction and operation.
As in the patent referred to, the wick-tube A is extended below the hollow plug or cap A', by which it is screwed into the neckof'a lampbowl to' reach to near the bottom of such bowl.'
The chimneysupporting base B is a circular disk of metal with a large central aperture fitting the hollow cap, on a collar, a, of which it rest-s, with a short downwardly-projectin g annular tiange, b, which is formed on its under side around the aperture. That portion of this base which is covered by the lower dome, l, is finely perforated, and around the edge of the domeare vlarger pert'orations tobe covered by the chimney E.
The dome G is gradually contracted from its junction with the chimney-base, to which it is soldered, presenting an unbroken concave outer surface until its sides come nearly in contact with the wick-tube; thence its sides are carried4 up parallel to the latter, forming an elongated neck or tube, C', which terminates at the upper end of the wick-tube and forms a narrow air-passage, c, around the same. The currents of cold air entering through the perforations of the base B under the dome `are thus caused to impinge against the wick-tube, andI kept in contact therewith until they issue at lthe top, in consequence of 4which the wicktube will be maintained at such a low temperature that its lower end may ysafely be iinmersed in the fluid in the bowl.
The upper dome or detlector, D, which has the usual llame-aperture above the wick-tube,
`is formed with the well-known slitted'tlange D', to serve as a chimney-holder, andrigidly secured to the lower cone by arms or posts d d. What I claim as my invention, and desire to secure by Letters Patent, is
In combination with the wick-tube A, which is extended below the cap A to reach to near the bottom of the lmnp-bowl, the dome C, when constructed with an elongated neck, C', to
form an air-passage around and to the top ot" the wick-tube, substantially as set forth.
In testimony whereof l have signed my name to this specification in the presence oftwo subscribing witnesses. l
