IMPROVEMENT IN LAMP-BURNERS.

To all about it may concern: I

Be it known that I, GEoRGE J. GAPEWELL, of West Cheshire, in thecounty of New Haven and State of Connecticut, have invented a new and useful Improvement in Lamps; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawings, forming a part of this specification.

The principal object of the present invention is to enable the wick of a kerosene-lamp to be lighted without necessarily removing the chimney; and for this purpose it consists in incasing the wick within a suitable-shaped metallic casing, tube, or holder therefor, of the requisite length, which casing is arranged and slides looselyin the ordinary wick-tube of the lamp, being operated by and through a pinion or spur wheel, interlocking with a toothed rack formed by indenting one side of the said holder in the direction of its length, and either moved outward or drawn into the ordinary wick-tube, carrying the wick with it, by turning'the said spur-wheel in the proper directions therefor, and this invention still further consists in a novel manner of constructing or forming the ordinary draft-openings in the cap portion of the lamp, for the admission and supply of air to its flame, whereby the air-currents are caused to be deflected, as they enter the air-ghamber of the lamp, and thus prevented from acting upon the flame with such force or strength as to extinguish it, the importance of which is obvious to all.

In accompanying plate of drawings my in'r provements in lamps are illustrated, Figure 1 being a central vertical section through a kerosene-lamp having my improvements applied thereto; Fig. 2, a horizontal section, taken in the plane of the line 00 00, Fig. 1; Fig. 3, a detail view of the wick-holder of the lamp.

Similar letters of reference indicate like parts.

A in the drawings represents the body portion of the lamp, having a top, B, applied to it, constructed in the ordinary manner practiced therefor, with the exception of the air-openings G to its air-chamber D, which are made in such a manner that the air-currents, in pass ing through them, must enter between the side edges, a and b, of the same, as plainly shown in Fig. 2, whereby they are deflected, as it were, in their course to the flame, and thus prevented from acting upon it with so much force or strength as to extinguish it, the our rents of air by this means being, as is obvious, so retarded in their course that, before reaching the flame, they 'must become heated to such an extent as to produce a more perfect combustion of the same.

F is the ordinary wick-tube of a kerosenelamp, but in the present invention made a little larger around its inside, in which is loosely placed another tube or casin g, G, in ade of a similar shape thereto, having the wick H properly inserted in it. This tube or casing G has a series of notches, 0 0, formed in it, upon one of its sides, at equal distances apart, and extending in the direction of its length, as plainly shown in Figs. 1 and 3, with which notches a pinion or spur wheel, I, engages, secured to a horizontal shaft, J, turning in suitable bearin gs of the top or cap B of the lamp, this shaft having a milled head upon one of its ends for convenience of turning it.

Kis abent'spring, secured at one end to the outside of the lamp-wick tube F, with its other end bearing against the opposite side of the wick-holder G to that with which the pinion I engages, as before explained, the objectof which spring is to hold or bind the said wick-holder G with a sufficient lateral force against the said pinion as to prevent the holdler from fallin g by its own weight through the wick-tube- F, no matter at what height its upper end, L, may be from the upper end of the wick-tube F.

The wick-l1older G it is intended should be made of such a length that its upper end, L, without its becoming disengaged from the pinion I and the wick-tube E, can be brought, by turning the pinion I in the proper direction therefor, above the upper end of the lampchimney M, in position forits wick to belighted, when, turning the pinion in the opposite direction, it can be then drawn down through the length of the chimney to the position desired, and its flame regulated, as with kerosene-ramps of the ordinary construction, the wick, in this instance, remaining stationary in its holder, while it is moved up or down, as may be necessary.

I claim as new and desire to secure by Let chamber of a coal-oil or other lamp as herein ters Pate11t described and shown in the drawings, for the -1.
