IMPROVEMENT IN LAMPS.

Specification forming part of Letters PatentNo. 129,821, dated July 23, 1872.

` My `present invention relates to a lamp-burner of the general character aforesaid; and consists in improvements in the construction of the parts for lessening the expense of manufacture and avoiding difficulties heretofore experienced.

In the drawing, Figure lis a vertical section of the said burner complete. Fig. 2 is a plan of the same. Fig. 3 is a sectional plan at the line w w, and Fig. 4 is a section of the wick-tube and the central disk of the supporting-arms.

The wick-tube a is provided with the ordinary wick-adjuster b, and this is within the screw-socket c, over which is the ratchet-cap d. Diificulty has been experienced in attaching the arms upon-which the glass chimney rests. In some instances they have been of sheet metal, extending from the ratchet-cap,

and in other instances Wire hooks have been i used. These are costly, or else liable to be bent.' I make the arms@ e each of a folded wire, branching apart sufliciently'iat the inner ends to enter two holes in the upper part of the sheet metal of the screw-socket c, and the ends are soldered or similarly attached inside said socket previous to the parts being put together; andin consequence of the divergence of the ends of these arms the wires brace each 4other rmly and make a strong support for the chimney. The perforatedair-distributer g and draught-plate h are made of the same piece of sheet metal, and around the edges of the draught-plate are springs 7c, that rest against the interior of the chimney. These parts have been before used, but the air-distributer has been sunk lower than .the surrounding draughtplate; hence there was a recess, into which the carbon from the wick and from matches was liable to accumulate, and could not easily be cleaned out. To avoid these difficulties I elevate the air-distributer so that it can be wiped off easily, and the removable cone or deflector k is guided in its position by the edge of said-air-distributer, andis held by a hook, 3, upon one side passing'through a mortise in h, and by a projection at 4, at the opposite side, entering a rccess in the flange of the deilector. The arms o, projecting om adisk, 6, that surrounds the wick-tube, hold the air-distributer and deiiector in position around the wick-tube, there being projections at 5 to sustain these arms uponthe wick-tube, and these projections are made by forcing out the sheet metal above and below the disk 6 at each edge of the wicktube. The disk 6 is stiii'ened by a rim around its edge, and the metal thereof is folded up against the sides of the wick-tube so as to make a very irm support by the said disk and arms for the deector..

I claim as my invention- 1. The chimney-support made of the foldedwire arms diverging at the inner ends, and entering holes in the screw-socket of the burner, and secured therein, as set forth.

2. The air-distributer g, raised above the surrounding draught-plate h, and sustained by arms that extend from the Wick-tube, in cornbin ation with the removable deflector, secured when in place as set forth.

3. The disk 6 with a rim around its edge,

and secured to thewick-t-ube in the manner specified, in combination with the arms o, airdistributer, and deiiector, as and for the purposes set forth.

Signed by me this 24th day of May, 1872.
