WICK-RAIS ER.

SPECIFICATION forming part of Letters Patent No. 511,572, dated December 26, 1893. Application filed August 23, 1892. $e rial No. 443,859. (No modehl To all whom it may concern:

Be it known that I, WILLIAM H. WILDER, a citizen of the United States of America, residing at Florence, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Wick-Raisers, of which the following is a specification, reference being had therein to the accompanying drawings. 7

My invention relates to a wick raiser for oil stoves, and is designed especially to make the connection secure between the spindle support and the part of the stove to which it is attached, so as to prevent disconnection of the parts, which often happens when this connection is made by solder alone, by reason of the great heat in the vicinity of the connection. With my connection, while the solder may be used, it is not depended upon to hold the parts together and may be used or not, as desired.

In the accompanying drawings, I have shown my invention as applied to an ordinary form of oil stove.

Figure 1 is a section taken horizontally of the wick tubes. Fig. 2 is a detail view of the wick raiserand the connecting disk. Figs. 3 and 4 are detail views.

In the figures, or represents the inner and, b, the outerwick tube, between which the wick c is raised and lowered. The usual tube connected to the Wick and. by which it is moved by the raising and lowering devices, is shown at d. To this tube d, a rack e is riveted or otherwise secured, of a suitable length, say three or four inches. The rack'is riveted to the periphery of the tube dand projects therefrom about an eighth of an inch. The outer tube 1) is provided with a vertical recess or groove on its inner face to receive the rack which moves therein.

In order to apply the wick raiser to the rack to operate the tube at, I cut out a small section from the shell of the outer tube b, inline with the rack, so as to insert the pinion f therein to engage the rack e. This pinion is carried on the end of the wick raising spindle g, which carries the ordinary disk h on the opposite end, and by which the spindle is rotated. The spindle has its bearings in an elongated sleeve 15 secured to a disk k which is provided with a flanged opening Z. sleeve is pressed through the opening until its inner end is flush with the inner face of the disk, and in this position it may be soldered to the disk. The disk It is eccentric to the position of the spindle and is substantially semicircular, having an inwardly to rned flange on its circular portion of slightly varying width, so as to fit against the rounded periphery of the outer Wick tube. The disk is also set at an angle to the sleeve for the same reason, namely, to better fit the periphcry of the wick tube. The left hand edge of the disk is straight, and has a flange m, which is'adapted to be bent down over the projecting portion of the tube b, forming the channel in which the rack moves. The pinion engages the rack and the flanged disk carrying the bearing sleeve covers the opening made for the insertion of the pinion,loeing soldered or otherwise secured to the outer surface of the tube 1). The disk is located between the outer wall of the wick tube and the shell inclosing the same, the tubular bearing 1 projecting from the disk and bearing against the'inner face of the shell while the sleeve 1' supporting the wick raising spindle fits the tubular hearing or flange closely, the outer end of the spindle passing through the casing of the lamp, thus providing a construction which prevents displacement of the parts even though the solder uniting them should become softened under the heat.

What I claim is In combination with the wick tube, a rack, a pinion engaging the rack, a disk covering the pinion and abutting against the outer wall of the wick tube, a projecting bearing extending from said disk abutting against the inside of the lamp casing and asleeve supporting the raising spindle engaging said bearing and supported by the casing at its outer end,

substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
