SPECIFICATION forming' part of4 Letters Patent No.` 740,425, dated October 6, 1903.

.tppncaitn ined August so, 1902. serial-nt. 121.598. on man To a/ZZ whom, t may concern:

Be it known that I, CORD EDUARD JOHANNES GRUBE, residing at Alt-Rahlstedt, near Hamburg, in the Empire of Germany, have invented certain new and useful Improvements in Lamp-Burners, (for which I have applied for a patent in Germ-any, and which application is dated February 5, 1902,) of which the following is a specification.A

This invention relates to improvements in lamp-burners in which a wick is employed, and has for its object to prolongthe life of the wick, to increase the efficiency of the wick by preventing the charred part of said wick interferingwith the iiow of the oil or other combustible hydrocarbon employed, to readily extinguish the flame when the wick is lowered, and to limit the height to which the wick can beraised. V

Various oil wick-burners have been provided with a cap covering one side and the rear surface of the wick and arranged so that the cap was moved by and with the wick upon the upward movements thereof until the cap was arrested by stops above and below. The object of these devices was to cause the wick to burn only upon the exterior, to limit the movement of the wickiwithin bounds which were found to be most suitable, and to extinguish the light automatically upon turn-ing down the wick. I InA these devices, however, the cap upon turning down of the'wick could The wick would then withdraw from the cap, and was thereby damaged at its upper end. These prior devices, moreover, .were all of special construction and adapted to only cerf tain makesrof burners. Y

The protecting-ringer wick-cap forming' the present invention is so constructed and arranged that while it is restricted in its upward movement it can move freely in the downward direction, so that the wick-cap upon turning down the wick is not torn away from the latter, but sinks with it into the wick-tube. In'this manner damage to the upper edge of the wick is prevented and the desired position of the wick may-be maintained. Furthermore, the' 'wick-cap is such that it can be readily adapted and applied to any of the ordinary types of oil wick-burners now on Vthe market. The wick-cap is so proportioned that it fits the space between the wick-tubes, and consequently will serve as an extinguisher upon turning downv the wick, although it does not, however, rest upon the wick-tube, but can follow the wick into the tubes.

The present invention therefore consists in the novel burner attachment hereinafter described and claimed, and illustrated in the drawings, in which- Figure l is a vertical section of a burner with my invention applied. Fig. 2 is a transverse section' on line 2 2, Fig; 1. Figs. 3, 4, and are detail sectional views, enlarged, showing the attachment in diiferentpositions.

f In said drawings, A designates abnrner of the Argand type, B the wick-tube, C the wick, and D the dame-deflector, all of which maybe constructed as in the commonly-known Argand burners. My attachment consists of a wick cap or ring E, which lits loosely between the inner wall of the wick-tube and the wick and is provided with an annular outwardly-projecting flange e on its upper end, whichrests upon and extends across the top edge of the wick. This wick-cap is adapted to follow the movements of thewick as the latter is raised or lowered. When raised, the outer side of wick between the outer wall of the wick-tube and the flange of the wick-cap is exposed for the combustion of the hydrocarbon, thus reducingthe liability of a charred part at the top ofthe wick interfering with lthe iiow of hydrocarbon. v

When the wick islow'ered, wick-.cap descends therewith and the aforesaid flange practically closing the space between the inner and outer walls of the wick-tube rapidly extinguishes the dame.

The extent to which the wick can be raised kis limited by a stop carried by the fixed part ICO Having thus described my invention., what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

In combination, a burner having an annu- 5 lar wick-tube, a wiok, a wick-cap tted loosely wick, so that the wick on being turned down is not drawn away fromthe wiok-eap, and means to limit the upward movement of the wick-cap, all substantially as and for the pnr- I5 pose described.
