IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 126,025, dated April 23, 1872.

clare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a central vertical section of my invention.

This invention has relation to lamps; and it consists in the construction and novel arrangement of the draught-tube and burner, whereby a draught of cool air is allowed to pass through a tapering tube, centrally placed in the oilreservoir, to the wick, which is designed to be arranged in tubular form, and operated with great convenience, as hereinafter described.

In the accompanying drawing the letter A designates the lamp-standard, provided with a receptacle, B, at its upper end for charred wick-clippings and refuse falling through the central tube. This receptacle is made of metal, and is secured to the standard by any desirable means. 1f the standard be of metal, the At the upper for the purpose of connecting the reservoir or bowl. 0 represents the reservoir for the oil, provided with a central tapering air-tube, D, extending up from an opening in the base of the globe to the opening at the top, through The upper end of the tube is smaller than the opening in the top, to allow of the passage of the wick, which extends downward on the outside of the tube into the oil-chamber proper. Internal screw-threads a a are provided in the upper and lower openings of the globe for the purpose of connection, respectively, with the burner and standard. The tapering form of the air-tube D is designed to give a powerful draught. E represents the stationary core of the burner, consisting of two concentric tubes, 0 and 0, secured together by means of an arm or loop, d. The outer tube b is provided with a screwthrcad around its lower edge for the purpose of connection with the globe. Above this screw-thread is an exterior flanch, e, which is provided with openings or slots for the recep- I tion of the studs f of the stationary base 9 of the shell. F represents the burner-shell, provided with a perforated stationary base, g, and an upper rotating burner-cone and chimneyholder, G, the flanch h of the cone-base being bent loosely over the periphery of the base 9 for the purpose of securing the rotary movement. The cone itself is double, consisting of a basecone, h, and upper portion, k, connected by means of a shoulder, l, perforated at i, for the upward passage of the vapor or gas rising from the oil through the notches m into the tapering portion of the wick-tube b. The upper portion 7a of the burner-cone extends upward from the shoulder l in a tapering manner, gradually changing into the cylindricalv form at the top. The inner wall of this cylindrical portion is provided with a spiral thread, n, by means of which the wick is raised or lowered when the burnercone is turned, the wick being kept from rotating by means of the ribs 8, arranged vertically about the exterior surface of the upper portion of the tube a of the core E. The lower portion of this tube is perforated with a number, of air-holes to permit a free communication of the air from the draught-tube to the inside of the wick. Air passes freely into the burner-shell through openings around its base-cone, and through the perforations of the stationary base g. The lower receptacle B in the standard is also provided with openings for supplying air to the draught-tube.

1 Instead of having the upper or perforated portion 0 attached to the burner-core, as above described, this portion may be continuous with the draught-tube, which, in such a case, will extend to the top of the burner.

The wick may be a wide band, or it may consist of two narrow bands, cylindrically arranged around the draught-tube. If this tube is entire throughout its length, no portion being at tached to the burner, a cylinder-wick may be used.

In consequence of the great draught through the tapering central tube of the reservoir, a tall per end and the concentric upper opening, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of ,two witnesses.

ABEL COMBS.
