BURNER FOR VAPOR-LAMPS.

Specification of Letters Patent No. 26,983, dated January 31, 1860.

To all whom it may concern:

Be it known that I, Annnnrus Gntenn, of Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Self-Generating Gas- Burners for Lamps; and I do hereby declare that the followin is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making part of this specification.

The nature of the invention relates to making the conical socket received into the lamp a nonconductor to prevent the heat from passing downward on the outside of said cone as more fully hereinafter shown.

With reference to the. accompanying drawings Figure 1, is a perspective view of a self generating gas lamp furnished with my improvements. Fig. 2, is a sectional elevation.

A, is the lamp.

B, is the cap which screws into the lamp in the ordinary manner.

0, C is the tube which contains the wick D, the upper portion being furnished with an internal screw, and the lower portion with an external screw, the two being made to fit each other for the purpose of making the tube adjustable in length, above the wick, thereby to increase or diminish at pleasure the product of gas and so increase or diminish the quantity of light without wapte of the burning or illuminating materia E, is the orifice where the gas escapes for combustion, on each side of the orifice E, is arranged a copper conductor F, which conducts the heat down to the tube G, G, which thereby becoming heated communicates its heat to the volatile fluid contained in the wick D, changing it to gas or vapor which then fills the space C within the tube and above the wick, and from whence it issues to the atmosphere through orifice E.

G, is a milled collar by which the screw joint of tube C C, is operated as described to lengthen or shorten the tube. Around the tube C C and secured to its lower end is arranged the hollow cone, or cup shaped socket I. This socket terminates at its top a short space below the flange B of the cap. Into this socket I, is fitted a piece of cork closely encirclin the tube C C and projecting upward far enough above the socket to receive and hold or be held firmly by the flange B on cap B, a space still being left between socket I, and flange B The cork thus arranged and secured and being itself a nonconducting material serves very effectually to prevent the heat supplied to tube C C, from being conducted or communicated in any objectionable degree to the cap B, or lamp A, within.

Outside the lamp and near the cap B, is arranged the flange H, around, and fast to, the tube C C This flange H, is in the form of a cup or the inverted frustum of a hollow cone and is for the purpose of protecting the cap B, and the lamps top from the heat which radiates from that portion of tube C G which is outside of the lamp.

The operation is substantially as follows: The lamp being filled with ordinary burning fluid or other illuminating liquid material, and the wick D, being arranged in the tube C, as shown it immediately becomes saturated by capillary action. Now a small wire brush or other suitable article being filled with alcohol is lighted and held within the conductors F. They immediately become heated andconducting the heat to tube 0 C the fluid in the wick D, is therebyconverted into gas or vapor which fills space 0 and escaping at the orifice E, takes fire and so keeps up the supply of heat to conductors F, so that the alcohol can be then dispensed with'and a beautiful flame of burning gas takes its place.

The material for the construction of the improved burner not already stated'may be such as is commonly employed for like purposes, and corresponding parts.

Having described the construction and operation of my improvement, what I claim therein as new and desire to secure by Letters Patent is as follows:

I claim making the cone piece I, I (which contains the nonconducting cork), with a break in the metal'at the upper end of the cone piece between I, I, and B B this space being occupied by a ring of cork instead of the metal, so that the heat of the In testimony of which invention I have burner and cap may not be conducted down hereunto set my hand in presence of Witthe tube I, I, substantially as herein set nesses.
