GEORGE TUPPER BROWN, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE- I-IALF TO THE MCCORMICK A; COMPANY, OF SAME PLACE.

LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 576,025, dated January 26, 1897.

Application filed October 6, 1896- T 0 all whom. it may concern:

Be it known that I, GEORGE TUPPER BROWN, of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Lamp-Burners; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in burners for lamps; and it consists in a combined lamp -burner, chimney-holder, and wickraiser combined with a plug attachment of cork or other suitable material adapted to fit in the neck of abottle or other oil-containing vessel and'hold the burner in place instead of the more complicated fastenin gs commonly used. In my burner the base plate, the spring prongs or fingers forming the chimney-holder, and the bearings to support and hold the wick-raiser in place are all formed out of one piece of sheet metal by stamping. The wick-holder is a single tube extending perpendicularly through the base-plate, the

portion thereof below the base-plate being fitted in the plug. Certain other peculiarities of the device will be hereinafter described, and the drawings illustrate the burner clearly.

Referring to said drawings, Figure l is a side vview of a lamp having my burner applied. Fig. 2 is a view of the burner detached. Fig. 3 is a vertical section through the burn er. Fig. 4 is a plan view. Fig. 5 is a vertical sectional View illustratinga slight modification of the burner.

The circular baseplate A has a shallow flange a on its edge, from which flange rises a series of fingers B, which constitute the chimney seat and clam p. Each of said fingers, as shown in Figs. 1 to 4, has a horizontal groove 1) in its inner face about midway of its length, said groove being preferably formed by bending the fingers, as indicated in the drawings, and the upper ends of the fingers are contracted and slightly curved outwardly, as shown. In two of the fingers B are perforations 19 for the reception of the wick-raiser rod 0, which is provided with a serrated wickraiser c and the usual handpiece 0. The wick-raiser 0 partially projects into the central wick-tube D and thereby keeps rod C $erial No. 608,056. (No modelJ from slipping longitudinally out of its bearings.

The wick-tube is preferably a short piece of round tubing extending through a central opening in the base-plate and fastened thereto by solder.

The tube projects gage the wick.

Fitted on the portion of the tube below the base-plate is a plug E, preferably of cork or compressible material,wl1ich may be fasten ed to the tube or base-plate, or both, by suitable cement or otherwise, and is adapted to fit tightly in the neck of an oil-containing vessel, such as a bottle or globe, and thus secure the burner in position. This plug has a vent e in its side to allow the escape of air when the burner is fitted to the vessel, and to allow the escape of gases, if any are generated in the vessel, so that the oil will not be forced up chimney on the burner.

No screws are necessary on my burner, however, for the fingers are made sufficiently resilient to bite the edge of the chimney and hold it in place, the grooves 12 forming both a seat and a clamp for the chimney.

It Will be observed that the chimney-seat is slightly above the wick-raiser rod, so that the chimney does not rest upon the rod, but is entirely supported by the fingers, and a space is left between the fingers and below the chimney for the admission of air to support combustion.

In the modification shown in Fig. 5 the fingers are shaped to hold a chimney with a straight vertical flange onits bottom, like the ordinary lamp-chimneys now most generally used.

I prefer the other form of chimney,

however, as the fingers clamp it in position sothat it cannot tilt over or drop off the burner.

The extreme simplicity of my invention is The base-plate and one of its chief merits.

fingers are formed out of one piece of metal by an economical stamping process. The wick-tube can be rolled or drawn, and the wipk-raiser and rod are the simplest obtainab e.

It is not upon the small number of parts that I lay stress, but upon the simplicity of their construction and their novel peculiarities.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is

1. The herein-described lamp-burner and chimney-holder, consisting of the base-plate provided with upstanding fingers on its periphery bent at a point above the base-plate so as to form both a chimney seat and clamp for supporting and retaining the chimney above the base-plate; combined with a wickraiser rod journaled in two of the spring-fingers which support the chimney,and the wickraiser on said rod, substantially as and for the purpose described.

2. The herein-described lamp-burner and chimney-holder, consisting of the base-plate provided with upstanding fingers on its periphery bent at a pointabove the base-plate so as to form both achimney-seat and clamp for supportingand retaining the chimney above the base-plate; combined with a wick-raiser rod journaled in two of the spring-fingers which support the chimney, and the Wickraiser on said rod; and a plug surrounding the wick-tube below the base-plate, adapted to fit into the neck of a bottle or other oil-receptacle and secure the burner thereto, all

substantially as and for the purpose set forth.

3. The herein-described lamp-burner consisting of a base-plate having an annular flange on its periphery and spring-fingers risin g from said flange bent as at b to constitute
