IMPROVEMENT IN LAMP BURNERS.

ANSON JUDSON, OF BROOKLYN, NEW YORK.

Letters Patent No. 59,772, dated November 20, 1866.

'S'PECIFIOA'I'IQIN' Of certain improvements in Lamps, invented by ANSON JUDSON, of Brooklyn, county of Kings, and State of New York. I I Nature and Objects .of the Intention.

This invention relates to that class of lamps known as kerosene or coal-oil lamps, and consists in constructing the main body of the burner, including the wick tube, of a single piece of metal, which is done by casting, and also in forming the shell of the burner with vertical slits or openings, for the admission of air to supply the flame, soform'ed that the burner can be cast in a two-part flask and without cores to form these openings, the objects being to make a cheaper burner, and at the same time to avoid the defects and liabilities to derangement which are consequent on making the wick tube and shell of two originally separate pieces.

Description of the drawings:

Fig. l'is a side elevation of the burner complete, with chimney ahd cone attached, and provided with a peculiar device for raising the wick.

Fig. 2 is a central vertical section of the same.

Fig. 3 is a side view of a skeleton frame for a cone suitable for said burner.

Fig. 4 is a plan of the same.

I General Description.

I make the shell, A, and wick tube, B, of this'burner in a single piece, which I accomplish by casting them of a suitable metal, which will stand the necessary heat and otherwise serve the purpose intended.

I prefer cast iron as the most suitable metal for this purpose, it being cheap, easily cast, durable, and otherwise answering the purpose well.

In the form which I have represented in the drawings this burner may be cast in a two-part flask, the parting being at the upper end or rim of the shell, and the hole in the wick tube for the wick being formed by a core. Any holes necessary for the admission of some device for raising the wick may also be formed by projections on the core which forms the opening for the wick.

In the drawings I have represented a needle, D, connected to the burner by a chain, as a suitable device for raising the wick, mortises being made in the sides of the wick tube to allow the needle to pass through the wick. I prefer this construction; but it is obvious that the ordinary toothed wheel, or other devices, may be used for that purposein this burner as well as in others, should such construction be preferred.

To avoid the difliculty in casting which would occur in perforating the shell of the burner with small holes, in the usual manner, for the admission of air to supply the flame, I make the shell of the burner with vertical slits or openings, sofornied that the burner can be cast in a single piece, without the use of cores to form these openings, as represented in the drawings.

I prefer to make the cone also of this burner either wholly of cast iron, as represented in figs. 1 and 2, or in part of cast iron, as represented in figs. 3 and 4, in which latter case I form a skeleton of castiron, as represented in the last-named figures, and make the sides of glass or other transparent or translucent material, orof some material which is a bad conductor of heat. I I

In figs. 1 and 2 of the drawings the chimney is represented as being secured in position by the wellknown device of inward projections on the shell of the burner and a screw, thoughit is obvious that other devices may be used. The projections may be formed by making indentations in the sand after the pattern is drawn, or by other means of forming such projections which may suit the convenience of the manufacturer.

' The shell of the burner, and also the cone, can be easily electroplated, lacquered, varnished, or bronzed, to give it a pleasing appearance.

It will be perceived that by this construction I avoid the ordinary expensive processes involved in the usual construction of burners of this class, while at the same time I avoid the-objection of a joint between thewick tube and the shell of the burner, and secure a more substantial and durable burnerat a less expense.

I claim as my invention- Claims.

First. Making the shell of the burner and the wick tube in a singlepiece, substantially as and to the effect hereinabove set forth.

Second. Making theshell. of the burner with vertical slits or openings, for the admission of air to supply the flame, when said openings are so formed and arranged as to permit the said shell to be cast in a two-part ANSON J UDSON Witnesses:
