LANTERN OR LAMP.

Specification of Letters Patent.

Patented Apr. 9, 1912.

' To all whom it may concern:

Be it known that I, CHARLES C. Bnmmn a citizen of the United States, residing in Revere, county of Suffolk, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Lanterns or Lamps, of which the following is a specification, reference being had to the drawings accmpanying the same and forming a part thereof. 7

My invention relates to lanterns or lamps.

The object of my invention is to provide means for supplying air to the burner or flame of a lantern or lamp from the top to promote proper combustion.

- A further object of my invention is to provide means to shield theflame of the burner from strong currents on gusts of air, thus to prevent the flame from flickering or from being extinguished. p

In the drawings. which accompany this specification and form a part thereof the figure is a sectional elevation of the lantern showing the construction of my top draft device.

The body 1 of the lantern is provided 'a sliding door 6 which slides upwardly on runways of the usual type in such lanterns.

The top of the lantern is composed of the irregular cone-shaped cover 7 which is part of or may be secured to the body of the lantern 1. The top is provided with an inwardly curving flange portion 8, the purpose of which will be more fully explained hereafter. A hinge-top 9 is pivoted to the portion 7 by any suitable form of hinge,

and it may be provided with a suitable-catch 10 to hold it in its closed position. The,

cone-shaped portion 9 has an inturned edge 11 which is provided with a series of holes 12, 12, etc., to permit the air to escape upwardly. It has a central opening of a size to inclose the cone 13. The cone 13 has attached to its lower end by rivets or otherwise a perforated inverted cone 14 having perforations all around its body'part. This inverted cone 14 has a flange portion 15 which fits in the inside of the top 7 and has L-shaped slots 16 adapted toinclose an inwardly projecting pin 17 to hold the cone 13 and the inverted perforated cone 14 in a the position shown in Fig. 1. Holes 18, 18, etc., are formed in the top 9 so that the upper edge of the holes come slightly below the upper edge of the curved flange portion 8. i

In operation, air is supplied to the burner 4 through the holes 18, 18, etc., flowing upwardly and over the edge of the curved flange 8, thence downwardly through the perforations 19,19,etc.,in the inverted cone 14, thence down on the inside of the lantern to the burners to supply sufficient air for the holes 18, 18, etc., it would strike the side of the inwardly curved flange 8, be deflected upwardly, as shown by the arrows, and pass out through the holes 12, 12, etc., to the spaces 20 under the canopy 21, and be carried out by the cross drafts of air over the top of the cone 13. This construction eifectively prevents strong currents of air and gusts from passing down through the holes 19, 19, etc., in the cone 14 to theinterior of the lantern or lamp. a

The form of the cones and the manner of attaching them together may be somewhat changed without departing fro-m the spirit of my invention. 7 1

What I claim is 1 1. In a lantern, a body casing having an air chamber in its top consisting of an inner imperforate tube and an outer casing having holes mid-way of its height; a perforated plate at the top ofthe casing having an i I i ineans of an inner imperforate tube and the outer casing of the body, the outer casing having holes approximately mid-way the height of said air chamber; a perforated 5 closure at the top of said air chamber; an outwardly and upwardly flaring perforated closure at the bottom of said air chamber secured to the bottom part of the inner imperforate tube and to the outer casing; and 10 an inwardly and upwardly curving wall eX- tending to approximately the top of the holes mid-way the outer casing.

In testimony whereof, I have hereunto set my hand, in the presence of two subscribing Witness, this the 15th day of September, A. D. 1908.

CHARLES C. BRIAND.
