KERosENE-'OIL BURNER.

Specification forming part of Letters Patent No. S/LSO, dated April 8, 186;.

To a/ZZ whom t may concern:

Be it known that l, PEELEY D. CUMMINes, et the cityof Portland, in the State of Maine, have invented a new and useful KerosenelOil Burner; and I dov hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, forming a part of this myspecication, in which like letters indicate the same parts, and in which drawings- Figure l is a longitudinal vertical section of my improvement, the lamp cone being thrown back from. over the wicktuhe, wick, and iiaine and there held in position, as hereinafter described; Fig. 2, a longitudinal verticalsection sliowingthe cone elevated above its seat, and with the center of the openin g 'in its top in exact line with the vertical axis of the lamp; I and Fig. 3, a like sectioinshowing the cone upon its seat and in its normal position for ordinary use upon the lamp.` l

In the drawings, A and A indicate the ordinary base and finishing of a kerosene-oil burner attached to the vneck of a lamp B, as shown in the iigures. To this haseand finishingl attach in any suitable manner, by4 soldering or otherwise, a sheathV C,ope`n at each end, and having a slot or opening d from end to end so formed as to inclose and guide a projection e upon a rod f during its verti` cal movement in said sheath.. Thcvrod f, as will be seen in the drawings, .is provided with.

a' circular shoulder gat lits lower extremity,\'

and at its upper extremity sustains a burnercone D, an arm 7i., extending from the base'of the cone,l being soldered V'or in .anyproper manner securely attached totheftop of -said rod, as shown.

'It will be observed that, at. the top of the sheath C a portion of the sheath is cnt away,`

an inclined plane with a shoulder i'eains't which the projection e abuts when'the cone is thrown into the position indicated lin Fig. l, and which projection and shoulder, b'ycomingf in contact, prevents -a further outward movement of LVthe cone, the gravi ty ofr the vcone and rodholding suehparts in such p01 sition when so placed.

Supposing the cone androd'to occupy the position shown in Fig. El, and that it is desir thc \\'ick,thc operator for this purpose will place his .finger against the circular shoulder g with a slightupivard prcssu re, whereupon the rod f will slide up the sheath C untilthe face of the shoulder g strikes against the bottom of the sheath, the projection e meantime traveling in the slotor opening d of the sheath, and, thus the cone l) will he made toassumc the position shown inFig. 2. The operator then by a slight forward thrust of his finger willcausc the cone to assume the position shown in Fig. l, thus leaving the wick and the .top'of the lamp uncovered. -When the cone is made to assume the position shown in Fig. 2, itw-ill he seenthat there can be only one lateral movement of the cone from such position, since, while the projection e is permitted Yto travel down on the incline plane if o'n one sidefof the sheath, it is prevented from moving in the opposite lateral direction by striking t,einst a portion of the top of `the sheath, which is opposite to that cutaway to form the incline plane. A

Again, supposing the cone to he in the position shown lin Fig. l, and'it is desired to re 'turn it to that shown in Fig. 3, the operator to effect this will by a slight quick cant of the lamp toward his person canse the projecl .tion e to ftravel up the inclined plane 1I, thus:

causing the cone to assume the position as shown in Fig..2, whereupon bythe mereforce of-'gravity the cone will be re'tnrnedto its seat onA the shoulder 1120i? thebase of theamp. In .other words, the cone, when' in position as shown in Fig; 1oan he returned tov its positionV as shown in Fig. 3 by its automatic action alone after the impulse is given it, as above described.

-It may,thns be seen that the objectof my invention Vis to soconstruct a lamp-topfoi burning kerosene-oil that the cone can be re moved to dress the wick without the liability of smoking the cone and glass chimncyby makingsuch removal in close relation or contiguity with the wick, and for this purpose I cause the conc ,first to he elevated in a verticaldirection :from its seat above the wick and Haine, and then to he revolved or turned laterally away from the plane of thelninp; and,

. further, that after the'cone is so turned away it maybe hy automaticlactloil with certainty returned in ih@v position shown in Fig. I

would also observe that by my construction' that portion of the metal burner which is pressed by the finger to 'eeet the removal of the cone, beingsituated faraway from the flame and disconnected from immediate contact iyith the main body of the burner, insures 'the operator aga-hist burning his inger during the act of manipulation, and that for the return of the co'ne to its seat no portion of the metal of the burner need be touched.

Itis evident that a burner might be constructed so as to have the `cone elevated in the first 'instance like mine, and 'then turn over and away from the ame, to do which the rod f might be held in au elevated position by the linger of the operatorl or by me ohanioal means, whereupon the cone could be made to turn back in the are of avertioal circle byprovid-ing it with a hinge 'in its arm 71; but this mode I deem objectionable and far inferiforjto that I have previously described. K KKK are hooks risingup from the base ot the cone, and beneath which the fiange at` the base of .a chimney or globe as ordina-- rily usedy upon kerosene-lamps is inserted, after which the clasp I, pivotecl upon the'sorew m, as shown, may be turned with its lip 'It olasping the top ofthe flange, and so confine shown of metal, might Ybe cut out from its flange or nase, anu `in its piace a-coneof glass or other material of same form, having a baseiiange, mig tbe inserted up through thering.

so left, andbe secured therein from beneath in the same manner I haveshown for securing a chimney ori-,top of the base of the metal cone.

vHaving thus described my invention, what I claim as new,"andvdesire to secure by Let-v 3. Removing the cone from its seat upon-V the lamp, first; by a vertical movement'and then by a lateral movement of ft'he. cone, .for the purpose specified.

' Vitness my hand, in the matter of my application for a patent for alcerosen e-oi'i burner, Pthis 12th (lay of March, 1862.
