JEFFERSON F. FOX, OF FOSTORIA, OHIO.

LAM P-BURN ER.

SPECIFICATION forming part of Letters Patent No. 437,684, dated October 7, 1890.

Application filed April 28, 1890. Serial No. 349.704. (No model.)

To all whom it may concern.-

Be it known that I, JEFFERSON F. Fox, a citizen of the United States, residing at Fostoria, in the county of Seneca and State of Ohio, have invented a new and useful Lamp- Burner, of which the following is a specification.

This invention relates to lamps, and more especially to the burners thereof and the devices for raising the wicks therein; and the obj eet of the invention is to provide a wickraiser that may be set to wicks of various thickness as well as disengaged entirely from the Wick when desired.

To this end the invention consists of the usual shaft carrying spur-wheels and men nted in slots in the body of theburner, aretractingrod extending transversely to said shaft and adapted to be set out or in, all as hereinafter more fully described, and illustrated in the drawings, wherein- Figure 1 is a front elevation of this burner complete. Fig. 2 is a transverse section of the same, and Fig. 3 is a horizontal sect-ion below the top plate.

Referring to the said drawings, the letter A designates the Wick-tube having therein the ordinary wick B, and O is the shaft or spindle having spur-wheels D, adapted to engage the side of the wick, whereby when the milled wheel E at the outer end of said shaft is turned the wick will be raised or lowered, all as is well known in this class of devices and as is common in the art.

Coming now to the present invention, T is a tube standing at right angles to the wicktube and just beneath the plate P of the burner, and within this tube is a rod R, having a threaded outer extremity O, as shown. Coiled around this rod, between the outer end of the tube T and a lug L on the rod, is a spring S, by means of which the rod is normally drawn in beneath the plate P. At its inner end the rod R is branched, as at Y, and provided with eyes I, which loosely embrace the spindle 0. Upon the outer threaded end of the rod R is a nut N, beneath which is a washer W, bearing against the end of the tube T.

The operation of this device is as follows: The parts having been assembled and the wick put in place at the lower end of the wicktube, it frequently happens that it is found very difficult to push the wick up to such a point that the spur-wheels D will grasp it. To avoid this difficulty the nut N on the outer end of the rod R is grasped by the operator and the rod retracted. This movement draws the spindle O outwardly away from the wicktube, its ends sliding in slot-ted bearings H provided for that purpose, and the wick has a free and uninterrupted passage through the wick-tube. As soon as the wick has been passed a sufficient distance into the wick-tube, the nut N is released and the force of the spring S throws the spindle C and with itthe spur-wheels D against the wick. The spindle can then be turned to raise or lower the wick in the ordinary manner.

It may be sometimes desirable to use wicks somewhat thicker than usual, and in order to permit this without interrupting the flow of oil through the wick, I have provided the nut N at the outer end of the rod R. Byturning this nut in the proper direction the rod can be drawn outwardly until the teeth of the spur-wheels D will hardly touch a wick of ordinary thickness, after which the thick wick may be inserted and adjusted, as above described. If it should happen that no spindle and spur-wheels were desired at all, the nut N could be turned in to such an extent that they would be drawn completely out of the slots in the side of the wick-tube, through which they normally project, all as will be clearly understood by a person familiar with devices of this general character.

I claim as the salient points of this invention-- 1. The herein-described wick-raiser, the same comprisingaspindle mounted in slotted bearings in the burner, spur-wheels thereon projecting through slots in the wick-tube, an independent spring pressing said spindle normally toward the wick-tube, a rod standing at right angles to said spindle having eyes loosely embracing the spindle and extending through the side of the burner, the outer end of the rod being threaded, and an adjustingnut thereon, as and for the purpose set forth.

2. In alamp-burner, the combination, with the wick-tube having slots in its side, the spindle jou rnaled at its ends in slots in the burner, and the spur-wheels on said spindle project ICC ing through said slots in the Wick-tube, of a tube carried by the burner at right angles to the wick-tube, a rod having a branchedinner end provided with eyes loosely embracing thespindle, said rod passing through said tube, a lug on said rod inside said tube, and a coiled spring between said lug and the outerend of the tube, the whole operating substantially as described.

3. In a lamp-burner, the combination, with the wick-tube having slots in its side, the spindle journaled at its ends in slots in theburner, and the spur-wheels on said spindle projecting through said slots in the wick-tube, of a tube carried by the burner at right angles to V the wick-tube, a rod having a branched inner .my own I have hereto afiixed my signature in presence of two Witnesses.
