be a i'uil, clear, and exact description of .the same.

In the drawing--V l Figure 1 is a side view oi' the chimney, partly in section, as indicated by the line n: z, iig. 2,. and applied s Figure 3 showsthe opposite side to .that represented in fig'. 1. f

:This invention relates to a lamp-chimne adapted to a fiat wick-burner, for .coal-oil and otherl ydrocar' bons, the chimney. 'itseif 'bein dastehen iii-me dii-er1 tion in `which .the iiame sp s, said iiattened portion a proximating -in form -an oblate's'pheroid,"andrising a ve a base and contracted neck.

A represents the chimney, which 'is of glu-ss, lhaving the parts a b, the former approximating in form to an obiatc spheroid, the upper part being lather more flattened or narrower than the lower part, as A seen in iig. 2.

The cbimney'has an opening, c, to admit of the passage of air through it, the opening c being directly over the top of the dame on the cone of the burner.

1 The part'bof the chimney, which may be termed the base, is of slightly conical form, and of snch a lengththat, when applied. to or fitted ohra burner, 'it f will extend npwardabont half` wayto the top of the l cone thereof, andV at the lower edge of tho a lian' is shown, so that the chimney may be heid to l,the urner as usual.

B, iig. 1, isthe bnmer, which .is screwed into the top of the fountainof the lamp asu'snai.

D, n conical jacket encompassing the same and E, n cone' or deiiector attached to' thenpper end'of thejacketD.,

These parts, which comprise the burner, may be seen in a patent previously granted, May 6, 1h62.

The/ upper part of the baseb is sunk inward ail around it, as shown ata', to form a neck, and this eontnscts the space or air-'passage d -all around the 'cone The' bue b and neck a are suiiicientiy large to ML mit of an air-passage, d, ot' requisite dimeul w onube- '/tween the jscketand neck, as shown in ii 1; 'an the o of the burner, upon whiehthe jue -t and buse venlence, as many persons cannot use a conti-action, ata', and a.A bulb ilattcncd ill the. tion -in which the 'iiame spreads, substantially nl' rest, isperforated, ltqadnlit ofair passing upward iutoj thejacket and neck, asf will be fully understood by referring to iig. 1.

. '.lbe contlactingpifi the air-passage (l Aall around the cone E quickens me draught inV .the vicinity ofthe base of the dame, and insures a. goed draught through 'the whole chimney and an abundant -supply o t oxygen to the flame, lwhile the oblate spberoidai form of the upper part a of thccbimney insures a nearly equal air-space all arnnnd the flame, the fiat sides of the latter beingoppo'site vthe dat sides of a. l

One Vside ofthe chimney or globe is ground, anl l shown atf, injigs. zzand 3,am1 the opposite si'de, g, is left plain or clear. When, therefore, a subdued light is desired, the lamp is turned so that the groundv s'ide will be opposite'to the person using the '13h85,' and when a full light is desired, the plain or clear si e is turned in said position.` I This isa ver-ygieat" oon- A bright iight without a gronndglobe or chimney, and other-sughi 'prefer a bright or intense light. The suriiice may be 'also ornnmbnted, as shown, if de'sh'ed.- l

vThis chimney admits ofthe lampv heilig carried about from place tosmace with the greatest facility, and at the same timc'comhines all the A:nlvantagea uf the ordinary glass lglobes hitherto u sed' in connection with a glass chimney.

What is claimed, and to be secured by Letters Iat cnt, is-

1. A lamp-chimney iliade with a circular base i, a

direcspecified. '2. A. lnmp-chimney'made with the conical base b, a flange atits lower edge, ands the contraction a betweensaid base -b and 'the' iiattened bnlb, as and for the purposes speciiied.` 3. IA glass lamp-chimney made lwith one side rough ened or ground, Aas land for thepnl'peses set forth. 4. A glass lamp-chimney formed with the i and contraction a', in combination with a lamp-burner having a iiatwick, substantially as set i'orth.-
