CHARLES E. ABBOTT, OF BOSTON, MASSACHUSETTS.

IMPROVED EXTINGUISHER FOR LAMPS.

Specification forming part of Letters Patent No. 55,973, dated July 3, 1866.

i To all whom it may concern:

Be it known that 1, CHARLES E. ABBOTT, of Boston, in the county of Suffolk 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 1 is a perspective view of a lampburner, representing my improved ex ti n guisher closed down over the wick. Fig. 2 is a vertical section through the same, with the extinguisher lowered to uncover the wick.

My invention has for its object to provide a simple, convenient, and eflicient means of extinguishing the light of lamps of various construction, whereby the usual operation of blowing it out and the disagreeable odor occasioned thereby are avoided and myinvention consists in surrounding the wick-tube with a supplementary tube provided with a lid or cover, which is closed over and thrown back from the wick, as the supplementary tube is raised or lowered, by operating a rod carrying a toothed wheel which engages with a rack at tached to the supplementary tube.

To enableothers skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

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

'1) is the wick-tube, around which fits loosely another tube, 0, provided with a lid or cover,

(1, pivoted thereto at 6. At one side of the tube 0, and projecting below it, is a flat strip, f, to which and the tube 0 is secured the toothed rack g, which is raised or lowered (carrying the tube 0 therewith) by means of the toothed wheel h, attached to and operated by the rod 0.

t'is an aperture formed in the upper divisionplate of the burner, to allow of the passage of the rack g and stripf when the tube 0 is lowered, the tube 0 being prevented from sliding olf above the wick-tube by the broad cog k on the toothed wheel h striking against the rack and interrupting its movement in this direc tion. 1 is the wick-regulator.

The lamp being lighted and the parts being in the position represented in section, Fig. 2, when it is required to extinguish the light the rod is simply turned in the direction of the arrow 3, raising the tube 0 until its lid 01 is above the surface of the lighted wick, when the weight of the lid, being unsupported by the side of the tube 1), is free to fall upon the wick and extinguish the light, while the top of the tube is closed down, so that all disagreeable odors, as well as evaporation and danger of explosion to which the ordinary methods of extinguishing lights are liable, are thereby avoided. If desired, a spring may be employed to throw the lid cl down upon the wick, and a spring may also be used between the two tubes I) and c, to increase the friction between them and keep the outer tube in place upon the inner tube at the required height when the lid d is closed.

Instead of the rack g, indentations may be .made in the side of the tube 0, for the toothed wheel h to engage in, without departing from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent as an improvement in extinguishers for lamps, is

The tube 0, with its lid or cover (I, and rack g, or equivalent, operated by the toothed Wheel it upon the rod 0, substantially as set forth.

CHARLES E. ABBOTT.
