GEO. RIMMINGTON, OF SOUTH BROOKLYN, NEW YORK.

LAMP FOR BURNING COAL-OIL, 86C.

Specification of Letters Patent No. 20,373, dated May 25, 1858.

To all whom it may concern:

Be it known that I, GEORGE RIMMINGTON, of South Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Lamps for Burning OoalOil and other Hydrocarbons which Require a Large Amount of Oxygen to Support Combustion; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings. making a part of this specification, in which- Figure 1, is a vertical central section of my improvement applied to a lamp. Fig. 2, is a horizontal section of ditto, taken in the line a, m, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in the employment or use of a perforated cap, formed of two parts and used in connection with two flat wick tubes placed at a suitable distance apart the whole being so arranged as hereinafter fully shown and described, that the flame will be supplied with a necessary amount of oxygen to support proper combustion without the aid of the usual chimney.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a lamp of ordinary construction and B represents a metal cap, which is formed of two parts a, 7), the lower part a, being screwed into the top of the lamp A, as shown clearly in Fig. 1. The lower part a, is of cup or dish-form flaring "outward and upward and surmounted by a vertical rim 0, which forms a shoulder or bearing for the lower edge of the upper part b, of the cap, see Fig. 1.

The upper part b, is of inverted cup, or conical form, and has an oblong slot cl, made through its upper end to receive the upper ends of the wick tubes 6, 6. These wick tubes are what are known as the flat kind, they are placed parallel with each other are secured to the lower part b, of the cap in any proper way and extend down a suitable distance into the lamp A, the upper ends of the tubes being flush with the upper surface of the part 6.

Both parts a, b, of the cap B, are perforated entirely around as shown at f, and the upper part b, is provided with a horizontal projecting part 9 which serves are a handle asshown in Fig. 2.

The cap B may be constructed of sheet metal swaged in proper form, or it may be cast, or may be constructed in any of the known ways. and the top of the lamp A, has a metal ferrule C, attached, provided as usual with a female screw to receive the screw of the cap B.

When the wicks h, shown in red, are lighted the rarified air will induce a current of air through the perforations f, of the cap, between the wick tubes c. e, and upward centrally through the flame as indicated by the red arrows. A current of air will also pass upward at the outer side of the flame also indicated by red a-rows. The flame therefore is supplied with oxygen both externally and centrally and in such quantities that proper combustion will be supported with out the aid of a chimney.

The wicks 71-. may be regulated at any time by removing the upper part b, of the cap B, so that the wick tubes are rendered accessible.

By this improvement the lamp may be carried from place to place with greater facility than if a chimney were employed, besides the flame is not rendered so sensitive, or is not so liable to flicker or give an unequal or unsteady light, as the draft is rendered more equal not liable to such fluctuation as when a chimney is employed.

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

The cap B, formed of two parts a, 6, perforated as shown and used in connection with the two tubes 6, e, the several parts being arranged relatively with each other and applied to the lamp so as to operate as and for the purpose set forth.

GEORGE RIMMINGTON.
