TUBULAR Lanrnnn.

Patented Feb. 2, 1909.

To all whom it may concern:

Be it known that I, FREDERICK K. WRIGHT, a citizen of the United States, and resident of Syracuse,in the county Onondaga and State of New York,have invented a new and useful Improvement in Tubular Lanterns, of which the following is a specification.

This inventionrelates to' the tubular lamps or lanterns in which the flame issues through a slot in the burner cone and the latter is surrounded by a perforated plate on which the globe rests and through which the outside air enters the globe around the burner cone. It is often found in lamps and lanterns of this kind that the flame becomes flaring or drawn out at'its ends far beyond the body of the flame. These drawn-out end portions of the flame often generate considerable smoke, while the body of the flame is smokeless, and this .smoke is deposited to a greater or less extent on the globe opposite the ends of the flame slot. When the flame assumes this objectionable form the difficulty is usually sought to be overcome by trimming off the corners of the wick, but this does not always secure the desired effect.

The object of my invention is to provide the lamp or lantern with means whereby this difficulty is avoided. For that purpose I provide the globe plate with deflectors opposite the ends of the flame slot, whereby the air issuing with the flame from the ends of the flame slot is confined and prevented from spreading and the flame is thereby confined at the ends and prevented from flaring or becoming drawn out.

In the accompanying drawings: Figurel is a perspective view of the lower portion of a tubular lantern provided with my improvements. Fig. 2 is a sectional elevation of the burner and globe plate, on an enlarged scale, the section being taken lengthwise through the flame slot. F ig..3 is an elevation of a tubular lantern embodying this invention.

Like letters of reference refer to like parts I in the several figures,

A represents the oil pot of a tubular lamp or lantern of any suitable or well known construction, B the air chamber upon the oil pot, C the air tubes connected with the air chamber, E the burner seated on the oil pot and provided withtheusual wick tube e, F the burner cone seated on the air chamher and provided above the upper end of the jfrom'turning around the burner cone.

wick tube with the usual flame slot f, and G the globe plate which surrounds the burner cone and rests upon the shoulder thereof.

H represents deflectors which are secured upon the globe plate in line with the flame slot and which project upwardly from the globe plate at a short distance outside of the burner cone. The upper portions of these deflectors stand opposite the ends of the flame slot and at such a distance therefrom that the air current issuing from the end portion of the flame slot strikes the deflector and is thereby deflected upwardly and prevented from spreading laterally. The flame is therebyprevented from becoming drawn out and smoky at the ends and the globe is kept clean and free from smoke.

The upper ends of the deflectors are preferably curvedoutwardly, as shown at h. The globe plate carrying these deflectors is held in the proper position with reference to the flame slot by any well known or suitable device which preventsthe globe plaIte n the construction shown in the drawing the lantern is one of the well known kind in which the globe plate is attached to upright side wires h by which the plate is moved up or down'and which prevent the plate from turning on the cone. The latter is prevented from turning on the air chamber by any of the usual contrivances, for instance, in the usual way by the wick-raiser shaft 71.

I claim as my invention:

1. The combination of a burner comprising a wick tube and a burner cone which surmounts the wick tube and is provided with a flame slot above the same, a. globe plate which surrounds the cone and is movable toward and from the burner, upright deflectors secured to the globe plate and arranged Outside of the cone and opposite'the ends of the flame slot, and means for holding the globe plate with its deflectors in line with the burner slot, substantially as set forth.

2. The combination of a burner comprising a wick tube and a cone which surmounts the tube and is provided with a flame slot above the same, a perforated globe plate surrounding the cone and movable toward and from the burner, and deflectors arranged on said plate and extending therefrom upwardly opposite the end portions of the flame slot, substantially, as set forth.

3. The combination of an oil pot, 711 air the end portions of the flame slot, substan- JO chamber on the same, a b urneriseated on the tially asset forth. oil'pot' and provided 'With Wick tu'be,' af 'Witne'ss my hand, this 14th day of May, burnecrl' eione ieatecili on thle air chamber amp].
