'-PECIFICATION forming part of Letters Patent No. 428,463, dated May 20, 1890.

Application filed July 2'7, 1889. Serial No.3l8,8l i. (N0 model.)

To all whom it may concern.-

Be it known that I, EDMUND S. ORooKETT, of WVoonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Lamp- BurnerAttachments; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification. My invention relates to certain improvements in wick-raisers for lamp-burners.

The object of the invention is to provide an exceedingly cheap, simple, durable, and easilyoperated wick-adjuster for lamp -burners, whereby the wick can be raised or lowered from any side of the lamp and without touching lamp or burner, thereby obviating the trouble and danger of having to turn a lamp around to find the thumb-head of the common wick-raisers and avoid soiling the fingers with oil and dust.

These objects are accomplished by and my invention consists in certain novel features of construction and in combinations of parts more fully described hereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side elevation of a burner provided with the present invention. Fig. 2 is a cross-section on the line 00 ac, Fig. 1, looking down. Fig. 3 is a vertical section on the line y y, Fig. 2.

The burner can be of any construction, and in the present instance has the burner-cap a and wick-tube b, in which a wick c is located. A horizontal rotary shaft d is journaled in the lower portion of the burner, and is provided with one or more toothed wheels 6 e, rotating therewith in vertical planes and projecting through vertical slots in the wick-tube into the interior thereof, with their teeth biting into the wick 0, so that when the shaft is rotated in one direction the wick will be raised and when the shaft is rotated in the opposite direction the wick will be lowered. One end of the shaft (Z is extended and is provided with a small pinion f, having rather long teeth. This pinion, if found most desirable, can be formed with an extended hub, through which the shaft extends, and the pinion is secured to the shaft by a screw or the like extending through said ext-ended hub.

Upon the lower screw-threaded end of the burner a threaded extension or coupling 9 is screwed, and is provided with a screw-thread at its lower end to enter the burner-opening of the lamp and at its upper end this coupling is provided with an annular flange 71,, and beneath this flange a ring '5 is screwed, having a corresponding fiange, and a disk or wheel j is loosely held and adapted to rotate between said flanges, which are located such a distance apart as to allow the wheel to freely rotate and yet prevent up and down wabbling of the same, and this wheel is preferably of such diameter as to extend outwardly beyond the burner, so that it can be easily turned, and is located directly beneath the pinion f, and is provided with a circular series of openings 70, through which the teeth of said wheel loosely project, and said openings are elongated and inclined, as shown,so that the teeth can freely enter and leave the same as the wheel is rotated. Thus it will be seen that when the wheel j is rotated the Wick will be either raised or lowered, and but a small fraction of a rotation of the wheel will raise or lower the wick considerably by reason of the difference in size between the pinion and circle of openings 70.

The great ease and rapidity by which the wick can be operated and the extreme cheapness, simplicity, and durability of this article are obvious.

This wick-raiser can be applied to any burner having a horizontal wick-raising shaft without changing the construction of the burner and by merely removing the usual thumb-piece or button from the end of the shaft and then shortening the shaft and placing the gear-wheel thereon and then screwing the coupling-sleeve carrying the flat rotary wheel on the screw-threaded end of the burner.

What I claim is 1. A lamp-burner comprising the hollow body threaded at its lower end, the wick-tube, and the horizontal wick-raising shaft having a pinion on its outer end, in combination with a coupling-sleeve to screw on said body, and a horizontal rotary wheel loosely centered on said sleeve, provided with means to engage said pinion, so that when the horizontal wheel is rotated by the hand the wick will be raised or lowered, substantially as described.

2. In a lamp-burner, the combination of the wick-tube, the horizontal rotary shaft having means to adjust the wick and provided 011 its outer portion with a gear having projecting teeth, a coupling-sleeve screwed on the threaded end of the burner and having a lower EDMUND S. CROOKETT.
