UNITED STATES PATENT EEICE N. NV. VILLIAMS, OF FRANKFORD, PENNSYLVANIA, ASSIG'NOR, BY MESNE ASSIGNMENTS, TO HIMSELF.

IMPROVED LAM P-BURNER..

Specification forming part of Letters Patent No. 35,860, dated July 8, ISC-2.

To all whom it may concern.-

Be it known that I. N. W. WILLIAMS, of Frankford, (Philadelphia, )Pennsylvania have invented an Improvement in (loal-Oil-Lamp Burners; and I do hereby. declare the following to be a full, clear, andexact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in certain improvements(fully. described hereinafter) in the burners of coal-oil lamps, said improvements being made with the view of dispensing with the usual glass chimney, preventing the smoke and disagreeable smell, and avoiding the complex passages and other appliances common to this class of coal-oil lamps.

In order to enable others skilled in the art to make and use my invention I will now proceed to deseribeits construction and operation.

On reference to the accolnpanying drawings, which form apart of this specication, Figure l is a vertical section of my improved coaloillamp burner; Fig. 2, an exterior view of the cap, and Fig. 3 a sectional plan ofthe same.

Similarletters refer to similar parts throughout the several views.

A is a cover screwed into the ,orifice at the top of the reservoir B, containing the coal-oil, a portion only of this reservoir being shown in the drawings.

Through the cover A, which is hollow,p asses the spindle C, on which are the usual wheels for raising and lowering the at wick in the tube D, the latter being secured to the cover. This tube is carried upward to a greater length than those of ordinary lamps,and is surrounded by the elongated casing or cap E, the lower end, e, of which is enlarged and made flaring, so as to overhang the cover A, the rounded top having the usual oblong opening. The' casing E is connected tothe wick-tube D by means of the strips 11, which are eut from the sides of the cap, bent inward, and notched at the ends, so as to :lit to the opposite edges of the wick-tube to which they may be soldered, thereby maintaining the casing in its proper position in respect to the said wick-tube.

In coal-oil-lamp burners as heretofore constructed for the purpose of dispensing with the ordinary glass chimney, chambers for heating the air admitted through perforatious and contracted passages for directing the heated air to the amehave been deemed indispensably necessary to prevent smoke and the disagreeable smell which generally accompany the flame of coal-oil lamps.

I have found, after many experiments, that the most thorough consumption of smoke can be effected by the simple elongated casing or cap E, between which and the Wick-tube is presented a chamber, F, the latter being entirely open below and presenting no obstruction to the free entrance of a plentiful sup.- ply of air, the progress of the latter upward being uninterrupted saving by the bentstripst' ,which occupy too insignificant aspace within the chamber to arrest the current of air through the same.

The air admitted without stint or obstruction below becomes heated in the chamber F, and rushes with such force through the oblong openingf in contact with the tiame as to cause the latter to burn with brilliancy and unaccom'panied with the usual smokcand disagree- The liame of the lamp, too, may be reduced in extent without becoming extinguished, which is the result of a reduction of the fiame of ordinary lamps; hence my improvement is 'especially applicable to lamps required for night use.

The covers of coal-oil lamps are generally so loose as to allow more or less leakage of theV gases generated in the reservoir, these gases causing a disagreeablesmell, which is avoided i by my improved burner, the lower end of the exterior casing, E, being flared and overhanging the cover, so that all vapors passing from the reservoir at the point m will be carried with the air through the. chamber F and consumed bythe flame.

As regards the construction of my improved burner, it will be seen that it is of the most simple and inexpensive character compared with other burners7 in which the complex passages and appliances hitherto deemed necessary for a thorough consumption of the smoke demand tedious manipulation to manufacture and great care to adjust and maintain in proper order.

I claim as my invention and desire to secure by LettersPatent- 1. The exterior casing, E, with its oblong openingf, in combination with the elongated Wick-tube D, when so arranged and connected together as to leave an unobstructed opening below for the free ad mission of air to the chamber between the easing and tube7 as set forth, for the purpose specified.

2. Flaring the lower end ofthe casing E so as to overhang the cover A and permit the gases passing from the reservoir at the point where the cover is secured to the same to pass upward into the chamber l), as set forth.

3. Securing the exterior casing to the Wicktube by means of strips i, bent from and forming part ofthe said casing, as specified.

In testimony whereofI have signed my name to this specification in the presence oftwo sub-4 scribing witnesses.

N. \V. VILLIAMS.
