IMPROVEMENT IN LAMP-BURNERS.

TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known thatl WIQLIAM McOAINE, of' Groton, in the county of Middlesex, and State of Massachusetts, have invented a new-'and useful Improvement-in Burners for Lamps;l and do hereby declare the same to be fully described inthe following specification, and represented in the accompanying drawings, of which- Figures 1 and 2 are vertical sections of a kerosene-burner" with my invention applied toit.-

Figure 3 is a top view of the annulus, to be hereinafter explained, and

Figures 4 and 5 are side elevations of it. l v I In carrying out my invention, I arrange on or about on a level with the top of the wick-tube, and so as to project equally over opposite sides thereof, a thin and narrow metallic'ring, which I aiix to a socket-tube, to t.

upon and encompass the upper part of'the wick-tube. This annulus or ring may be constructed with two projections or ears, to extend upward from it at'opposite extremitiesof its diameter, vand so as to be against the edges of that part of the wick which may project above the wick-tube. I

In the drawings, A denotes the wick-tube, B the body, and C the conical air-deilector of the burner, they being made and arranged in the usual manner. D is the annulus, mounted'on and aiiixed to a socket-tube or clasp, a, and having ears, b b, extended up from it, as represented. The wick-tube is for what is termed 'a hat wick, and the annulus is circular. I

It has been found that the addition of the an'iiulus to and its arrangement with the wick-tube, in manner as' described, createan important improvement in the illuminating properties of the dame of the wick. To

operate to the best advantage, the annulus should not extend below the top of the -wiclr-tiibe.v It contracts the dame at the edges of its base, and extends it, in its middle, justabove the wick-tube, and there directs the air upon it in a manner to promote combustion of the oil to good advantage.

l I do not pretend to explain all' the reasons why the dame .is improved in its light-giving property by my invention, with reference to the common pyramidal air-director, described in R. S. Merrills patent of June 14,-

1859. I have found, in practice, that my invention not only renders such an air-director unnecessary, but causes the dame to give out a better and greater amount of light, and renders it less liable to smoke; therefore,

I make no claim to a conical or pyramidiil air-deflector, to extend around and below a wick-tube, or below and a short distance above it; norv do'I claim either ofthe air-deiiectors, as shown in Figures 6 and 7 of the drawings, of J. C. Ambroses patent, dated April 23, 1861. 'n

The diierene between my deector and these latter is, that its projections, I b, extend entirely above the annulus D, whereas the parts a a, which, in the said iig. 6, correspond to theprojections b-b, arearranged entirely below vthe tops of theparts r r of the ring, whereby any contraction of' the flame widthwise at its base would be counteractedby its breadthwise contraction, occasioned by the parts r r. My annulus is circular, and although operating to conduct air to the flame, leaves, by its lateral extension from the-wick-tube,in opposite directions, ,thelame'a chance to spread in breadth, and thus enables the parte b I: to perform their oce to good advantage. v i I I therefore' claim my' improved air-deector, as made, with its partsb b arranged above the rest of the' ring and with respect .to the t'ubea, so as when in use to contract the flame widthwise at its base,'as set forth.

WM. M CCAINE.
