LAMP.

Patented Jan. 27, 1914.

Application filed December 4, 1912. Serial No. 734,965.

To all r'LC/omit ntaj/ conve/n:

Be it known that I, T .TOMAS OBiunn, a i citizen ot the United States, residing at'` Brooklyn. in the county ot Kings and State. i of New York. have invented certain newI and useful Improvements in Lamps: and l i 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 apperta-ins to make and use the saine,

This-invention relates to lamps and stoves and more particularly to that-type using wicks and has tor an object to provide means for exposing more or less ot' a portion ot the wick so as to-increase or decrease the flame.

A further object of this invention is to provide a. simple device havingthe least number ot parts using' a. wick which does not vary its vertical movement with respect to tht` reservoir of the lamp or stove.

.t further object of this invention is a provision ot' a removable tip which when charred may be thrown a l'ay to avoid the trimming of the wick.

A furthe" object of this invention is a provision of a wick which terminates at the bottom oi the reservoir at. all times so as to absolutely drain the reservoir.

.ft further object of this invention is the provision ot' an adjusting means tor exposing more or less of the wick which adjusting means serves as a support tor a globe or chimney.

A further object of this invention is the provision ot an adjusting means 'tor exposing more or less of the wick which ad3usting means is rotatable to vary its relation with respect to the Wick.

Further objects will be apparent from the following specification, appended claims and drawings. in Which. r

Figure i is a vertical sectional view through a lamp constructed in accordance with this invention, Fig. 2 is a horizontal sectional view on the. line 22 of Fig. l, and Fig. i, is a similar view'on the line 3-3 of This invention provides for a stationary nate at the bottom of the reservoir at all times so as to drain the entire contents ot theI reservoir and has a further provision for trimming of the wick as by a removable tip which may he replaced when charred.

ln retaining the wick in stationary position it is necessary that. some vertically adjustabli` means be provided to expose more or lessI ot the wick so as to diminish or intens' "v the fiame.

Hotel ring' to the drawings there is shown a reservoir l0 havin;r the central air passage ll which terminatesl above the reservoir as shown and is provided with a perforated hood l). The top ot the reservoir is formed to provide an opening 13 which is internally threaded to receive the externally threaded sleeve 14 which sleeve has its interior spared from the air duct 1l to admit the wick 15 which terminates near the top ot the air duct 1l. and at the bottom of the reservoir 1t) so that as long as any oil remains within the reservoir, the wick exerts its absorbing action and conducts the oil to to t'orm a covering over the end o't'the Wick lo to prevent that portion of the wick from burning` and this hood is Jfurther provided with a depending flange 17 which fits Within the air duct ll. The air passages 18 through the hood are disposed so as to directcurrents ot air within the annular llame to promote con'ilmstion and enlarge the iian'ie.

The sleeve 14 is rotatable in the threaded openingy 13 so that rotation thereof in one direction causes a downward motion of said sleeve whereas rotation in the opposite direction raises thosleeve so as to cover more or less ot the tip 16. The sleeve is provided with a. flange 19 which terminates in a bead t'or manipulation thereof and this fiange is also provided with a series ot' erforations 20 to admit air between the g' obe 21 and the tip lf3 to support combustion.

The operation of the lamp is obvious and it is clearly seen that rotation of the disk 14 in one direction covers the tip 16 so as to extinguish the tiame While rotation in the other direction exposes the wick so that the same may be lighted and there is an adjustnient for any range ot' exposure of the wick.

Modifications may be made within the scope of this invention and I do not restrict myseltl to the form'shown which is submitted for illustrative purposes only.

Having thus described my invention, I claim:

1. In a burner, a reservoir, a central duct therein, said central duet rising above the level of the reservoir, a textile sectional Wick about the central duct, a sleeve carried by. 4said reservoir, said sleeve having adjustment with said reservoir by circumferential movement, an annular flange carried by said sleeve and a eap carried by said central duet for said duct and sectional wick.

2. In a burner, a reservoir, a central duct therein, said central duct rising above the reservoir, a stationary wick in said reservoir about said central duet., a longitudinally movable sleeve in engagement with and about said wick, said sleeve having direct threaded engagement with said reservoir, a Cap carried by said central duet and a removable section o-t' textile wick superimposed on said stationary Wick,

il. In a burner for lamps or stoves, a reservoir a stationary sectional wick about said central duet, a sleeve having threaded eonl nection with said reservoir and having longitudinal movement with respect thereto, said sleeve surrounding said Wick sections, a perforated flange carried by said sleeve, a chimney carried by said flange outside of the perforations and a cap carried by said central duct said cap overhanging said duct to form a' shoulder over said Wick sections and said cap having a perforated wall in4 alinement with the exterior of said Wickv sections.

4. In a burner, a movable sleeve serving as a closure for a reservoir and as a regulator for eX osing a wick, said sleeve com prising a tu ular member having a smooth inner surface, a perforated flange formed on the periphery thereof spaced from one end, a bead formed on the periphery of said iiange, said tube having a port-ion of its length cut in screw threads, and said tube being plain for an interval between the sri-ew threads and the opposite end thereof.

In testimony whereof I aix my signature in presence of two Witnesses.

THOMAS OBRIEN.
