IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 58,392, dated October 2, 1866.

To all whom it may concern:

Be it known that I, A. M. DUBURN, of Ohicago, in the county of Cook and State of lllinois, have invented a new and Improved Lantern; and I do hereby declare that the followin g is a full, clear, and exact description thereof, which will ,enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a side view of my invention, partly in section; Figs. 2 and 3, detached per spective views of the wick-adjusting mechanism; Fig. 4, a plan or top view of the same;

Fig. 5, a section of Fig. 4, taken in the line as a0.

Similar letters of reference indicate like parts.

This invention consists in a novel manner of constructing the lantern, whereby all parts of thesame are rendered accessible for repairs and cleansing purposes, the wick rendered capable of being adjusted higher or lower without detaching the lamp from the lantern, and the lamp supplied with a burner which does not require a draft-chimney.

A represents a lamp, which is attached to a flange, B, the latter forming the base of the lantern. The upper surface of this base has an upright annular rim, a, secured to it, with a bead, b, at its upper edge, under which flanges c c on the lower edge of the bottom band, 0,; of the body of the lantern project, as shown in Fig. 1, the lamp A and band (J being by this arrangement connected together, while they are allowed to turn freely.

The lamp is fitted in and withdrawn from the lantern by shoving the flanges 0 through recesses c in the head I), one of the said re cesses being shown in Fig. 1. v

D represents the wire guards of the lantern,

which may be constructed and arranged in the usual way, the lower ends of the uprights being secured to the band C.

The upper horizontal guard, d, has the cap E of the lantern. secured to it by a hinge, c, and said cap is provided with a catch, f, by which the cap is secured down on the guard d when the lantern is in use.

The cap E may be constructed in the usual manner and provided with a handle, F.

G represents the glass globe of the lantern,

the lower edge of which has a metal band, 9, upon it. This globe rests upon spring-supports h h, which are attached to the inner sides of the band C, the globe being allowed to fit within the guards, so that it may be withdrawn therefrom down through the band (l when the lamp is removed, the lower part of the cap E, when secured down on. the guard 01, fitting over the top of the globe G and retaining it in position. The globe may be withdrawn at any time by simply pulling out ward the spring-supports h h, the lamp being previously withdrawn.

H represents the burner of the lamp, which has a flat wick-tube, 2', provided with two plates, jj, at its upper end, which project out horizontally from two opposite sides of the wick-tube, and are then bent over toward the wick, as shown clearly in Fig. l, and have their edges curved and their ends bent down ward, as shown in Figs. 4 and 5.

By this arrangement an air chamber is formed around the upper end of the'wick and the base of the frame is spread, so that it will be thin and have a large area exposed to the air above the edges of the plates jj.

The wick is raised and lowered by means of the usual serrated wheels fitted on a rod, 70,

which passes horizontally into the base of the burner. The outer end of the rod 70 has a square, Z, upon it, as shown in Fig. 3, and through the band C a short horizontal rod, m, passes, with a socket, n, at its inner end to receive the squarel of rod 70. The squarel may be fitted in the socket a by turning the lamp A or the band C, and, the rods k and at being thus connected, the wick may be raised and lowered .by turning the rod in, and, consequently, without removing the lamp from the lantern.

When it is necessary to remove the lamp from the lantern, the lamp or the body of the lantern is turned so that the square l will be out of the socket a, and the rods 1: .m will consequently be detached, the rod m remaining in band 0 when the lamp is withdrawn.

The lamp may be lighted, without? removing it from the lantern, by raising the cap E.
