LAM P-WICK RAISER.

SPECIFICATION forming part of Letters Patent No. 472,354, dated April 5, 1892. Application filed November '7, 1891. Serial No. 411,133. (No model.)

To all whom it may concern.-

Be it known that I, HARRY H. HIPWELL, of Long Island City, in the county of Queens and State of New York, have invented a new and useful Lamp-Wick Raiser, of which the following is a full, clear, and exact description.

This invention relates to a novel wick-raising device that is used in connection with tubular lamp-wicks; and it consists in the peculiar construction and combination of parts, as hereinafter described, and indicated in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of the oil-chamber and burner of a lamp with the improved wickraiser in position engaging awick, the chamber being broken away to show the construction of the said wick-raiser. Fig. 2 is a sectional plan of parts shown in Fig. 1, taken on the line 2 2 in said figure; and Fig. 3 is a reversed plan view of the wick-raising device detached from the lamp.

The lamp-chamber A may be of any preferred form and the burner B of an approved construction adapted to receive a tubular wick O, that is held in position at the point of ignition by a center tube a and an outer concentric wall b, as indicated by dotted lines in Fig. 1.

The wick-raising device consists of a flat bracket-plate c, curved slightly edgewise to allow it to lie close to the lamp-wick, as shown in Fig. 2. The bracket-plate c is provided with a sleeve d, that projects from one side at right angles thereto, having a sufficient length to engage its upper end with a perforation in the cap-plate e of the lamp-chamber in which it is secured, so as to lie inclined, as shown in Fig. 1, thereby supporting the bracket-plate at a proper distance below the cap-plate and inclined oppositely to the pitch of the sleeve. The length of the bracket-plate c is proportioned to the diameter of the wick O, and near each end a star-wheel g is imposed thereon and pivoted thereto so as torotate freely, the wheels being loosely secured on the lower surface of the bracket-plate. At a point equally distant from the pivot-centers h of the starwheels 9 a perforation is made in the plate that is a continuation of the bore of the sleeve d, in which a shaft 2 is loosely inserted. On the upper end portion of the shaft i, which projects above the sleeve d, a thumb-wheel m is affixed, and on the lower end of said shaft, that projects below the bracket-plate c, a starwheel at is secured, the diameter of which wheel is so proportioned as to mesh its teeth with the teeth of the similar wheels g. The inclined position of the bracket-plate c and proportionate diameter of the star-wheels g, together with the edgewise curvature of the bracket-plate, will cause the wheels 9 to impinge their teeth upon the tubular wick O in different planes vertically considered, their degree of separation between the pivot-centers h allowing them to bear in such a manner as to impart a spiral progressive movement to the wick, which will elevate it if the wheels are rotated in one direction and depress said wick if a contrary revoluble motion is communicated to the wheels 9 by a manipulation of the thumb-wheel m.

By provision of the bracket-support for the star-wheels 9 any desired degree of separation may be given to the latter when the device is constructed, so as to enable the wheels to engage with the wick at a proper distance apart, which is necessary for the efficient operation of the device.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A lamp-wick raiser comprising a bracket plate, spaced star-wheels mounted to rotate on the bracket-plate in the same plane, a shaft j ournaled in the bracket-plate at a right angle thereto and carrying a star-wheel intermediate of and meshing with the spaced starwheels, and means for revolving the shaft, substantially as described.

2. A lamp-wick raiser comprising an inclined bracket-plate held in the lamp-body and having a central sleeve projected at a right angle thereto,-spaced star-wheels rotatably supported on thebracket-plate in the same 'plane and engaging a tubular wick in the lamp-body, a shaft revoluble in the sleeve of the bracket-frame, a star-wheel at the lower end of the shaft, meshing with the spaced wheels, and means for revolving the shaft, substantially as described.

IOC

3. The combination, with a lamp-body and a burner therein having a tubular wick, of a bracket-plate having a central sleeve and held at an incline in the lamp-body, two spaced star-wheels rotatably supported on the bracket-plate and engaging the tubular wick, and a shaft revoluble in the sleeve of the bracketplate, provided at its upper end with a thu1nbwheel and at its lower end with a star-wheel located between and meshing with the spaced to wheels, substantially as described.
