THOMAS SCOTT WILLIAMS AND FREEMAN AUGUSTUS TABER, OF BOSTON,

MASSACHUSETTS.

Letters Patent No. 105,020, elated July 5, 1870.

To all to whom these presents shall come Be it known that. we, THOMAS SCOTT WILLIAMS and. FREEMAN AUGUSTUS Tanna, of' Boston, in the county of Suffolk and Commonwealth of Massachusctts, have made an invention of a new and useful Improvement in Lamps, or devices for burning candles and do hereby declare the following to be afull, clear, and exact description thereof, due reference being had to the accompanying drawing making part of this specification, and in which- Figure l is a vertical section and,

Figure 2 an under-side view of a portion of a lamp for burning candles, containing our invention or improvement.

This invention is an improvement in a class of lamps or burners in which a candle is forced Anp to and against a cap or cover, over which isv placed .a deiiector or coue,` as it is universally termed, when applied to kerosene-lamps. c

lhis invention relates to means for protecting or insulatiug a'caudle from' direct radiation of heatfrom the inflamed wick of the same, as well as to prevent the flame from creeping downward into or upon the cap or cover of the candle, theobject of such protec,-

tion being to prevent the melting or softening of a considerable portion of the candle bythe said flame, which superfluous softening or liquefaction, it is hardly necessary to say, seriously interferes with the propel' combination of the candle, as it floods its wick, clogs and disiigures the working parts of the lamp, and is objectionable in many respects.

The invention consists in intel-posing between the vupper part of a candle and the main lportion of,its

llame, or the upper portion of the detlector or cone surrounding such dame, and directly over the orifice of the candle-slnmounting cap, a-slotted plate or shield, which, while interfering in nowise with the perfect combustion of the candle, shall, nevertheless, insulate it to a great extent from the direct radiation of heat from the flame-of the wick, prevent downward passage of the ame, and retard and arrest, in a corresponding proportion, the meltingor softening of the candle,

which would intelferewith the successful operation of candlesof this class'. 1 l

The drawing accom panyng this specification exhibits at a the metallic deiector orcone; at b, the cap or inverted cup, which receives the upper end of the candle, such portion of the candlebeing represented in the drawing at c, and a portion of the outer case or shell of the lamp or burner at d, such elements constituting part of a device for burning candles, and being arranged in proper order.-

` Within the upper part of the delicctor a, and immediately below its dame-orifice or apex e, wedispose and affix a metallic plate or bar, j, which extends across t the said burner, and has an orifice, g, formed centrally in it, to coincide with that of the apex e, though preferably of somewhat less area. v

Heat radiated downward from the darne of the wick will be spent, to a considerable extent, upon the shield and the flame itself be cut ol, and divert both from contact with the candle, thus greatly retarding the melting or softening of `the body of the latter.

XVe have made suciently extended experiments to prove the correctness of our theory with regard to the shield j, and thefact that much less diiculty is experienced in the use of the lamp provided with it, from stoppage ofthe working parts from softened or melted parafliue, as is now frequently the case.

A considerable economy in waste of material is also effected by the use of our present invention, 'as little, if any, more is softened lthan is sufficient to feed the wick. l

We are aware that a slotted plate has been used before in-a burner for oil-lamps, toV prevent the heat from passing down through the wick-tube to the oil reservoir, but o ur invention differs from this, in that the slotted plate is not combined with a wick-tube, but with the cone or defiector a, and the cap b, which receives the upper end o f the candle. to prevent the dame creeping down through the orifice in the cap b into the caudleand is so shaped as to cover that portion of the top of the candle exposed by the orifice in the cap, so that the combined action of the cap and the plate is to shield the candle from the direct action of the heat of the dame.

What we claim, therefore, a-nd desire to secure by Letters Patent, is

In a candle-lamp, the combination with the defiec-v tor or cone a, and candle-cap b of the slotted plate or shieldy, interposed between said parts, 'substantially' in the manner and for the purposes set forth.
