BURNER FOR OIL-LAMPS.

SPECIFICATION forming part of Letters Patent No. 623,443, dated April 18,1899.

' Application filed January 19,1898. Serial No. 667,180. (No model.)

To all whom it may concern:

Be it known that I, CECIL THROOKMORTON, gentleman, a subject of the Queen of Great Britain, residing at Greylands, Glennies Creek, near Singleton, in the British Colony of New South VJales, have invented a new and useful Improved Burner for Oil-Lamps,

of which the following is a specification.

This invention relates to an improved burner for oil-lamps, which though specially devised for lamps such as those for domestic purposes in which kerosene, paraflin, or like high-grade oil is used is yet applicable to all lamps in which hydrocarbon oils more or less easily vaporized are used.

This improved burner for oil-lamps consists of two main partsa tip and a vaporizingcell, the former forming the top of the latter, the bottom of which latter is in connection with an oil'reservoir. The tip is made of refractory heat-conducting material of more or less porous nature, such as plaster-of-paris or such as fire-clay or the like, mixed with combustible material, but out of which the said combustible material has been burned. This tip is perforated and is firmly fixed to the top of the vaporizing-cell, which vaporizing-cell is filled or nearly filled with fibrous or spongy materialsuch as tow, cotton-waste, or the likeor with other material which will split up or divide the oil.

In one construction of this improved burner, which is used when the oil-reservoir is above the level of the burner, the bottom of the vaporizing-cell is connected to said reservoir by a bent pipe having a regulating-tap or other device, such as a bird-fountain connection or other means, for regulating the amount of oil supplied through the bent pipe to the burner.

In a modified construction of this burner, which is used when the oil-reservoir is below the burner, as in ordinary hand or table lamps, the vaporizing-cell is affixed to the top of the wick-tube, and the ordinary wick terminates in the fibrous or spongy filling in said cell.

In order to the saving of the oil, to the prevention of the charring or burning of the filling material of the cell, and to the speedy extinguishment of the lamp, a movable head is combined with the burner, adapted to stand clear of the tip and to closely fit over the tip when required to cut off the supply of oxygen thereto; but in order that this invention may be clearly understood reference will now be made to the drawings herewith, in which Figures 1 and 2 are cross-sectional elevations at right angles, respectively, of one construction of this improved burner for oillamps specially devised for use on a lamp having the oil-reservoir above the level of the burner, and these views show the extinguishing cap or hood in position closed over the tip. Figs. 3 and 4 are a central sectional elevation and a plan, respectively, of a modified construction of burner for use on an ordinary hand or-table lamp or a lamp having its oilreservoir below its burner, and in these views the extinguishing cap or hood is shown as elevated clear of the tip, and in Fig. 4c the burnercone is removed. Fig. 5 is an enlarged crosssectional elevation of the burner; Fig. 6, a plan of the tip, and Fig. 7 a longitudinal ele vation of the burner. p

A is the tip; B, the vaporizing chamber or cell; 0, the oil-supply pipe or wick-tube; D, an ordinary slotted burner-cone, and E an ordinary chimney gallery or support. The tip A, of refractory and porous material, has perforations A as shown, medially of itslength, and it has grooves A into which spring the upper edges 13 of the vaporizing-cell B, thus firmly holding it in position. The lower parts A of this tip extend downwardly, as shown, into the filling B of the vaporizing-chamber, said filling being of a fibrous or spongy nature, such as the materials before mentioned, or asbestos or any other material which will split up or divide the oil which enters the Vaporizing-cell. In the burners shown in Figs. 1 and 2 this vaporizing-cell Bis connected with branch pipes C to the main supply-pipe O,which has'a tap or valve C or other contrivance for regulating the supply of oil to said vaporizing-cell. In the construction of burner shown in Figs. 3 and 4 this vaporizing-cell B has an inset channel or socket B adapted to tightlyfit over the top of the wick-tube,which wick-tube contains an ordinary wick O as shown, dipping into the oil-reservoir. On the side of the vaporizing-cell Bis hinged at F contained therein burns and so heatssu'ch tip and its downward extensions A causingthe oil in chamber or cell B to vaporize, and this escaping through the perforations A in the tip burns and emitsa good and steady illuminating-fiame.

which operates rod F and lever-F causin the cap or hood F to fall over on its hinge F and closely fit the tip A, and thus cut off the supply of oxygen and smother or extinguish the flame. In using the burners shown in Figs. 1 and 2 it is necessary to out off the flow of oil to the burner by manipulating the tap or valve C? or other regulating contrivances.

It is to be understood that though I have shown what Iconsider to be the best construc- 1 tions of this improved burner, yet I do not confine myself to the precise details described and illustrated so long as the nature of this invention be retained.

In extinguishing the lamp the thumb-piece F is pushed to operate lever F 7 Having now particula rlydescribed and explained the nature of my invention and in what manner the same is to be performed, I declare that What I claim is- 1. In a burner for oil-lamps, the combination with the vaporizing-cell B, and a filling B of fibrous or porous material placed in said cell, of the perforated refractory tip A having in its sides the grooves A into which are sprung the upper edges of the vaporizing-cell and provided on its under side with projections A that are extended into the filling in the vaporizing-cell, substantially as described.

2. In a burner for oil-lamps, the combination of the vaporizing-cell B having a filling B of fibrous or spongy material, the perfo-
