LAMP-WICK.

SPECIFICATION forming part of Letters Patent No. 399,277, dated March 12, 1889.

Application filed April 7, 1888.

T0 all 1071.071@ 'it mf/y] con/c0770:

lie it known that I, AUoUs'r MUELLER, of Kansas City, Jackson county, Missouri, have invented a new and useful Improvement in Lamp-ll'icks, of which the following' is a full, clear, and exact description, reference being had tothe accompal'iying drawings, formii'lg a part hereof.

My invention relates to tubular lamp-wicks, andhas for its object to pro videa more cheap, simple, and effective wick than has heretofore been in use.

\Vith these ends in view myii'lvention consists in the peculiar features and arrangement of parts more fully described hereinafter, and pointed out inv the claims.

Referrii'lg to the aceomlianying drawii'igs, Figure l.l is a sectional elevation of a centerdraft lamp provided with my improved wick, and Fig. 2 is a perspective of the wick applied to the center tube of a lamp.

The refererice-letter A indicates the upper portion of my wick, and may be formed integral with the lower portion, or may be sewed or otherwise secured thereto. This upper section, A, is made tubular, and is adapted to slide upon the center tube of the lamp by means of any suitable raising and lowering dcyice. The remainder of the wick consists of the slit portion 1:3 and the lower tubular section, l). The portion l is slit longitudinally, and thus divided into a number of strips, ll', which connect the upper and lower tubular sections of the wick.

The operation of my device is as follows: The wick is placed upon the center tube of the lamp, with the lower tubular section, l, around the bottom of said tube. The upper portion, A, is then slid downward until its top registers with the upper extremity of the center tube, thus causing the several strips "3 to diverge from the center tube and spread over the bowl of the lamp. The lamp is'then filled with oil, and as the wick burns the upper portion, A, is slid upward by any suitable means; but the lower section, Z1, always remains at the bottom of the tube. lVhen the wick has been used until the lower extremity of the upper portion, A, reaches the top of the center tube, a new upper portion is attached and slid down upon the eenter tube, and the operation just described is repeated. Thus by employing my device all the oil in the bowl of a lamp is used lup bei fore refilling becomes necessary, for the reai Serial No. 269,903. (No model.)

son that the lower extremity of the wick always remains at the bottom of thc bowl of the lamp.

The advantages of this form of wick are: As the wick is slit intermediate of its upper and lower extremities, it iiaeilitates placing the same in the lan1p,because thelower tubular portion can be more easily slid down over the central tube, whereas in wicks where the strips are disconnected at their lower ends the operator would be obliged to grasp all of them in his hand and hold them together while inserting the wick into the lamp. In my construction the lower end of the wick will always reston the bottom of the bowl of the lamp by reason of the friction between the wick and the central tube. The strips will diverge uniformly from the central tube of the lamp, and therefore feed a more regular and full supply of oil to the upper portion, as found by actual"'usc. Besides producing these beneficial results, the wick presents a finished, symmetrical, and ornaniental appearance when in use. The wick being constructed in the manner described greatly :facilitates packing, shipping, and handling of the same, as it can be reduced to the form of a flat wick and packed in a Very small com pass. It can be more cheaply manufactured, as it is slit intermediate of its upper and lower extremities, and consequently the ends of the strips do not rcquirebinding to prevent them from unraveling.

ll avin g thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A lamp-wick composed of a pair ol' tubular sections connected together by separated longitudinal strips, inthe manner and for the purpose described.

2. In a tubular lamp-wick, the combination of an upper tubular section adapted to slide upon the center tube of a lamp, a lower tubular section adapted to remain stationary at the base of said center tube, and separated longitudinal strips connect-ing said upper and lower tubular sections, in the manner and for the purpose set forth.

In testimony whereof l afiix my signature in presence of two witnesses.

AUGUST MUELLER.
