UNITED STATES PATENT FFICE CHARLES E. ABBOTT, OF MALDEN, MASSACHUSETTS.

IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 59,534, dated November 13, 1866.

.To all whom it may concern:

Be it known that I, GHARLEs E. ABBOTT, of Malden, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Extinguishers for Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a perspective view of a lampburner, representing my improved extinguisher closed down over the wick. Fig. 2 is a vertical section through the same, with the extinguisher lowered to uncover the wick; Fi g. 3, detail, to be referred to hereafter.

My invention relates to that class of extinguishers for lamps for which LettersFatent of the United States were granted to me on the 3d day of July, A. D. 1866, in which the wick-tube was surrounded by a supplementary tube provided with a lid or cover, which was closed over and thrown back from the wick as the supplementary tube was raised or lowered by operating a rod carrying a toothed wheel engaging with a rack attached to the supplementary tube; and my invention consists in operating this supplementary tube by means of a lever, instead of the toothed wheel and rack before mentioned, thus enabling me to simplify the construction and reduce the cost of manufacture.

To enable others skilled in the art to understand and use my invent-ion, I will proceed to .describe the manner in which I have carried it out.

In the said drawings, Arepresents the perforated casing of an ordinary kerosene-lamp burner, the cap B, which supports the chimney, being secured to a flat metal strip, e, which slides up and down through an aperture in the bottom of the burner in a wellknown manner.

b is the wick-tube, around which is fitted another tube, c, which slides up and down, and is provided with a lid or cover, cl, which is hinged thereto at e, the points upon which it is hung being placed so far above its upper surface as to insure its falling by its own weight when the lamp is held in a vertical position.

necessary degree of friction to hold it in/ place at the required height when the lid cl is closed.

A stop, g, is also formed on the tube c, to prevent the lid el from being thrown back too far, and this stop may have a slight spring, if desired, to assist iu throwing the lid down over the wick.

h is a lever, which works on a rod, l', as a fulcrum. This lever is iiattened at its outer end, as seen in Fig. 1, and at its opposite end is formed an open slot, k, Fig. 3, which may be either straight or curved, and in this slot works a pin, l, which projects from the tube c, so that as the lever h is operated the tube will be raised or lowered to close or open the lid rl, as required, the throw of the leyer being such that the tube c will be carried up sufficiently high to prevent the lid d, when closed, from striking against the top of the wick.

The lamp being lighted, and the parts being in the position represented in section in Fig. 2, when it is required to extinguish the light, it is simply necessary to place the finger on the ilattened end of the lever l1l and depress it, when the tube c will be raised until its lid l is above the surface of the lighted wick, when the lid, being unsupported by the side of the tube b, is free to fall by its own weight over the wick and extinguish the light, while the top of the tube c is closed down, so that all disagreeable odors, as well as the evapo ration of the oil, are avoided; and by the employment of this extinguisher all danger of explosion resulting from the ordinary method of extinguishing lights by blowing them out is prevented.

When the lamp is to be lighted it is only necessary to raise the outer end of the lever h, so as to lower the tube c and uncover the wick.

Claim.

What I claim as my invention, and desire l CHARLES E. ABBOTT.
