SPECIFICATION forming part of Letters Patent No. 575,606, dated January 19, 1897'.

Application filed February 17, 1896. Serial No. 579,610. (No model.)

To all whom, it may concern.-

Be it known that I, AUGUSTUS H. JONES, of Meriden, in the county of New I-Iaven and State of Connecticut, have invented a new Improvementfin Lamp-Burners; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be afull, clear, and exact description of the saine, and which said drawings constitute part of this specification, and represent, in-

Figure l, a view in side elevation of one form which my improved lamp-burner may assume; Fig. 2, a view thereof in vertical central section; Fig. 3, a detached view of the tubular wick-carrier and the rack, the pinion coacting with the rack being also shown; Fig. 4, a detached view in inside elevation of the chambered head which receives the pinion and guides the rack; Fig. 5, a detached view of lthe bearing-tube of the gallery.

My invention relates to an improvement in burners for lamps of the central-draft type,

lthe object being to provide a simple, compact,

convenient, and effective burner combining in one device a rack-andpinion wick-adjuster and a vertically-movable gallery constructed to permit a lighted taper to be applied to the Wick without removing the lamp-chimney.

With these ends in view myinvention consists in a lamp-burner having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claim.

In carrying out my invention, as herein shown, the perforated skirt or body A of the burner has located within ita chambered bearing-head B, receiving the pinion C, which is mounted upon the inner end of a shaft O', journaled in the said bearing-head, which is constructed with an outwardly extending sleeve B', forming an extended bearing for the said shaft, the outer end of which projects beyond the sleeve for the reception of a spindle D, provided with a finger-button D, the sleeve bein g secured to the shaft by means of a transverse pin d or in any other approved manner. The inner face of the head is constructed with a vertical guideway or slot c, which receives the upper end of the rack E and holds the toothed edge of the same in engagementwith the pinion C. The

lower end of the said rack is secured to the lower end of the tubular wick carrier F, which is adapted to iit within the outer wicktube G, which formsa member of the burner. The said tubular wick-carrier is constructed, as herein shown, with three vertically-arranged spring wick-gripping jaws F', the upper edges of which are bent inwardly to form wick-gripping teeth f. These jaws, it will be understood, ride upon the inner periphery of the outer wick-tube, while their teeth f project inward sufficiently beyond the inner periphery of the tubular wick-carrier to take into the wick for holding the same.

By rotating the spindle D in one direction or the other through the medium of its n gerbutton D the pinion C will be correspondingly rotated and act through the medium of the rack to positively raise or lower the tubular wick-carrier, and hence the wick.

The gallery H, which is provided, as herein shown, with a globe-holder I-I' and chimneyholding lingers H2, both of which may be of any ordinary construction, is also provided with a depending bearing-tube I, conforming in diameter to the diameter of the central opening of the gallery and spun over the extreme upper edge thereof, as shown in Fig. 2, to form the retaining-flange t'. This bearingtube is cut away to form large lighting-openings I, affording the ready access to the wick of a lighted taper when the gallery is raised, as shown in Fig. l. The webs I2 formed between the lighting-openings inclose springfingers I3, formed integral with the bearingtube and located'at the lower ends of the said openin gs, the said ingers riding upon the eX- terior surface of the outer wick-tube when the gallery is depressed and springing, when the gallery is elevated, into a circumferential groove I4, formed in the upper end of the outer wick-tube, and comprising a square shoulder located at its upper end, against which the springs impinge for preventing the bearing-tube, and hence the gallery, from being disconnected fromthe outer wick-tube, and hence the burner, the `said groove also comprising a beveledlower portion, permitting the springs to ride easilyout of the groove when the gallery is depressed. I do not, how- IOO ever, limit myself to a vertically-1norable gallery constructed and arranged exactly as described.

I would call attention to the fact that in my improved lamp-burner as organized the rack extends upward within the skirt or body of the burner and between the same and the outer wiek-tube, and also between the same and the bearing-tube of the gallery, which is cleared by the rack, so that neither oneinterferes with the other, although they perform their offices in virtually the same main portion of the burner and in closely adjacent parallel vertical pla-nes.

It is apparent that in carrying out my invention some variations from the construction herein shown and described maybe made. I would therefore have it understood that I do not limit myself to the same, but hold myself at liberty to make sneh changes and alterations as fairly fall within the spirit and scope of my invention.

I elaim- In a burner for central-draft lamps, the combination with a burn er-body, of an outer wicktube secured by its lower end thereto and ris ing centrally therein, a verticallyunovablc gallery comprising a depending bearing-tube fitting over the ripper end of the said outer wick-tube and having lighting-openings, a tubular wick-carrier fitting within the'said outer wick-tube and adapted to enga-gc with a wick, a rack secured by its lower end to the said carrier and extending upward into the said burner-body in position so that when the bearing-tubc is moved up and down it will clear the said rack, and so that when the rack is moved up and down it will clear the said bearing-tube, and a horizontally-arranged spindle mounted in the burner-body, and provided at its inner end with a pinion located within the burner-body and meshing into the said rack for raising and lowering the same and hence the carrier, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

AUGUSTUS ll. JONES.
