WICK-LIFTER.

SPECIFICATION forming part of Letters Patent No. 513,059, dated January 16, 1894.

Application led April 5,1893,

To @ZZ whom t may concern:

Be it known that I, JOHN REID, of Wheeling, in the county of Ohio and State of West Virginia, have invented a new and useful Improvement in Wick-Lifters, of which the following is a full, clear, and exact description.

The invention is illustrated in the accompanying drawings, forming part of this specication, in which- Figure l shows in side elevation a lamp provided with my improved wick-lifter, part of the bowl being broken away to reveal the interior construction. Fig. 2 is avertical central section through the interior of the bowl.

In the drawings, 2 represents thebowl of a lamp, 3 the central tube, 4 the wick carrier, which is movable vertically thereon and which is connected to the lower end of the wick in suitable manner. All these parts are old and may be varied in construction without affecting my invention.

5 is a vertical rod which extends from the base of the bowl parallel with the wick and is unattached at the upper end.

6 is a spirally-formed wire, which encircles the rod 5, and at its upper end projects-from the bowl through a guide-tube '7, and is provided with a tliumb-piece 8, enabling it to be rotated upon its longitudinal axis. `By reason of the iiexibility of the spiral, the guidetube may be curved or inclined so as to project outwardly, without interfering withsuch rotation.

The wick carrier 4 is provided with one or more pins or projections 9, which extend in proximity to the rod 5, and are adapted to bear against the spiral wire 6. They are preferably two in number and lit on both sides of the rod. The consequence is that if the spiral be turned axially by means of the thumbpiece, its bearing upon the pins will cause the wick-carrier, to be moved vertically on the central tube, and as the pitch ofthe spiral can be great without danger of weakening the construction, a comparatively short turning of the thuinb-piece will sufce to move the wick-carrier with the wick vertically a sufficient distance' for the ordinary adjustment of the wick in the lamp. The spiral wire may be prevented from being moved vertically byprovidingit at its upper Serial No. 469.160. (Nomodel.)

end with a collar 10, which tits a removable nut l1 on the guide-tube. I may, however, dispense with such devices, in which case the spiral may be used, not only by turning 1t as above described, but it can be pulled up lengthwise in order to elevate the Wick rapidly in the manner of the ordinary directlift rods. The lower end of the spiral is preferably free, as shown in the drawings, so as to enable it to` be easilyv screwed into place from the exterior of thelamplbowl when the parts arerst adjusted. I

The advantages of my invention will be appreciated by those skilled in the art.

The device is veryv simple, compact and strong, and the rapidity of its adjustment overcomes effectually the difticulty which has before been experinced in the use of screw wick-litters. l

vWithin the scope of my invention as defined in the following claims, modifications may be made by those skilled in the art, since l. In wick-litters, the combination with a wick-carrier, of a liexible spiral rod or wire which extends into the lamp-bowl from the exterior thereof, and which engages the wickcarrier and is rotatory to raise the same, and an inclined guide tube through which the spiral passes; substantially as described'.

v 2. In wick litters, the combination with a wick-carrier set around the central tube of a lamp, of an upright rod arranged in the lampbowl atl the side of said central tube, and a rotatory spiral rod or wire encircling theiipright rod and rotatory on its longitudinal axis around the same, said spiral rod or wire engaging the wick-carrier and being adapted to raise the same substantially as described.

3. In wick-litters, the combination with a wick-carrier set around the central tube of a lamp, lof an upright rod'arranged in the lampbowl at the side of said central tube, a rotatory spiral rod or wire encircling the upright rod and rotatory on its longitudinal axis around the same, 'said spiral rod or wire engaging the wick-carrier and being adapted to raise the same, and a guide-tubethrough which the upper end of the spiral projects, substantially as described.

4. In wick-lifters, the combination with a IOO Wick-carrier, set around the central tube of a to impart adirect lifbto the wick-carrier; sublalnp', of an upright rod arranged in the lampstantially as described.
