MINOR H. FOWLER, OF NEW YORK, N. Y.

iMP ROVEMENT IN LANTERNS.

I Specification forming part of Letters Patent No. 40, 10! dated October 27, 1863.

To. all whom it may concern:

Be it known that I, MINOR H. FOWLER, of the city, county, and State of New York, have invented a new and Improved Lantern 5 and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in Which Figure 1. is a side view of my invention, the lower part of the lantern being in section, as indicated by theline w 00, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line 3 3 Fig. 1; Fig. 3, a detached view of one of the springcatches pertaining to the same.

Similar letters of reference indicate correspondin g parts in the several figures.

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

A represents the glass globe of the lantern B, the metal cap 5 U, the guards, and D the metal band at thebase of the globe A.

E represents the lamp, the upper part of which is provided with a burner, F, having a flat wick-tube,- a, and a serrated wheel and shaft, G, for raising and lowering the wick.

This burner and wick-adjusting mechanism,

are of usual construction, and, therefore, do not require a minute description.

1 H represents the base of the lamp, which is struck up or formed out of a single piece of sheet metal, with a flange or rim, 1), at its edge, and a plane horizontal part, c, to which the lower edge of the lamp E is attached, the part c ofthe base H forming the bottom of the lamp. This part 0 of the base H is sufficiently larger in diameter than the lower part of the lamp to admit-of openings d being made through it between the lamp and a cylinder, 6, attached thereto. (See Figs. 1 and 2.) This cylinder 0 extends upward about as high as the top of the lamp E, and is of such diameter that the band D, at the base of the globe A, may fit into it. The shaft G extends over the top of the cylinder 0 and projects a trifle. beyond it, so that the thumbwheel f on its outer end will be at the outer side of the lantern, and a slot, g, is made vertically into the band D, to receive the shaft G and admit of the band D passing down into the upper part of the cylinder 0. (See Fig.1.)

By this arrangement the wick may be raised and lowered without detaching the lamp from the lantern, and by an exceedingly simple means, which does not augment in the least the cost of manufacturing the lantern. By having the base H of the lamp constructed, as shown, out of a single piece of metal, with openings d made in it, and the part cof the base made to serve as a bottom for the lamp,

the cost of construction is very materially reduced. The openings cl, it will be understood, are for admitting air into the lantern to feed the flame, or supply it with oxygen and prevent the flame being extinguished by a vertical movement of the lantern. The lamp E is secured in the lantern by means of springcatches I I, which are constructed out of a single piece of metal, as follows: A strip of sheet metal is slotted vertically a distance rather more than half its length, so as to form two legs, it, one of which, i, is secured to the lower part of the cylinder at its inner side, to form a spring, and the other leg, 6, being bent so as to project at right angles through an opening, j, in the cylinder 0, and bent downward at its outer end to form a button, is, for the thumb or finger to press against. The upper parts of the catches are bent so as to have a portion, I, nearly at right angles to the leg 4, and are then bent upward in an inclined position, as shown at m. This upper bent portion of the spring forms the catch, the portions Z catching over a horizontal flange, a, at the bottom of the band D. The inclined portions m of the catches admit of the flange n as it is pressed down within the cylinder 0 forcing inward the catches, so that the flange a may pass below the portions 1 and the latter be forced over the former. By constructing the spring-catches I in this manner they may each be formed of a single piece of metal and constructed at a small cost. The trouble of soldering buttons on the catches is avoided, and no manipulation of any kind required except the securing of the catches to the cylinder 0.

I do not claim, broadly, the arrangement of airoriflces in the bottom of the lantermnor the use of air-tubes in the bottom. The 0011-. struction of such air-tubes involves considerable expense.

Having thus described my invention, whatI may all be formed of a single pieceof metal,

as specified. a

2. The combination of the springs I I, cylinder 0, and rock-shaft G with the band D and slot or opening g, all in the manner herein shown and described.
