IMPROVEMENT I N LANTERNS.

Specification forming part of Letters Patent No. 105,339, dated July 172, 1870.

To all whom it may concern:

Be it known that 1, JOHN H. IRWIN, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Lanterns; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, in which Figure 1 is a perspective View of my lantern. Fig. 2 is avertical central section of the same.

Fig. 3 is a vertical section of base-plate; Fig.

or protector, and extending a greater or lesser distance above the top of said protector, and supporting a cap or cover fashioned to permit the escape of the products of combustion either through or beneath it but in .my lantern, herein shown and described, no such band is employed. The globe or protector extends above the top of the guard-frame, and

is so fashioned as to form the top of the lantern, and a seat for a retainin g-sprin g. The cap or cover, through or beneath which the products of combustion are permitted to escape, is hinged to one side of the guard-frame, and shuts down close over the globe or protector.

Similar bands .havealso been employed at the bottom of thelantern to receive and hold globe or protector, and said bands obstruct the light and cause an objectionable shadow to be cast from the lower part of the lantern. I have dispensed entirely with a lower band, such as described, and seat the lower end of the globe or protector upon the bottom plate of the guard-frame, so

that no opaque substance projects above the lower edge of the globe to obstruct the light.

That others may fully understand my invention, I will particularly describe it.

What I denominate the frame of my lantern consists of the base-plate or bottom A, guards B, and top plate, 0. The bottom or base A and the top 0 consist of a single plate perforated in the center. The bottom plate is perforated to receive the lamp D or the candle-socket D, and the top plate, 0, is perforated to permit the globe or protector E to be inserted. The guards B penetrate the plates A O, and their ends are secured by solder at the back of said plates. In this manner the frame of a lantern is made both cheap and strong.

In lieu of a plate at G, a suitable wire may be employed, if desirable to reduce the cost of manufacture to the lowest possible sum.

The globe E is constructed at its upper end so as to form a shoulder, M, surrounding a short neck, N. The globe E thus becomes a fine or top to conduct awaythe products of combustion, without any metallic extension, such as is commonly employed, and a retaining spring-collar, H, is securely seated upon the shoulder M, and is kept in position by the neck N, as shown in Fig. 2.

The cover F may be hinged at one side of the plate 0, and secured by a spring, G, at the opposite side, so that if it is desired to remove the globe for cleansing, or to replace it if broken, the cover F may be thrown back and the globe uncovered. I

A spring-collar, H, is placed within the cover F, and as said cover is closed said sprin g rests upon the upper part or shoulder of the globe, and presses upon said shoulder, so as to retain the globe in place.

The bail or handle I is attached to cars J, which are secured to the plate 0, so that when suspended by said bail no part of the labor of supporting the lantern is sustained by the cap F or top of the lantern.

The lamp D or the candle-socket D is inserted through the opening made in the base A, and is retained in place by the thumbsprings K K.

The globe E rests upon the base-plate A, and the bottom of said globe is about level with the bottom of the oiLpot of the lamp D, so that as the lantern stands upon the ground, or any other surface, the light from the lamp may radiate freely, and none of the light be cut off at the base by surrounding bands.

Air to support combustion finds entrance to PATENT FFIGE.

the inside of the globe by passing beneath its lower edge, and to insure a free passage for it small projections L are made by indenting the metal of the base from the lower side, and the globe rests upon the summit of said projections. A clear space is thus left below the edge of the globe sufficient for the admission of the necessary draft.

From the foregoin g description it will be perceived that I have produced a lantern of singular simplicity of construction and facility of illumination. 1

Having described myinven tion, What 1 claim as new is- 1. The globe E, constructed at its upper end with a shoulder, M, and neck N, as and for the purpose set forth.

2. The globe E, constructed at its upper end as described, and at its lower end so as to sur- J. H. IRWIN. [L s.]
