IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 4S,S5S,dated July 18, 1865.

and letters thereon.

It will be seen by reference to the drawings which form part of this specitication that the guard is attached at its upper part to the dome of the lantern, and is detachable from the oth er parts of the lantern as one piece with the dome, leaving the glass or globe and the bottom, with `thelamp, as distinct and separate parts. This connection of the guard a with the dome b is clearly represented by Figure 1 of the drawings, while the globe or glass c and the bot- Y tom and lamp d and e are shown as separate pieces by Fig. 2.

Fig. 3 is a bottom view ofthe lamp and the flange that constitutes the bottom of the lan tern, the spring-catchesf, that secure the bottom to the lower ring or bar ot the guard Vbeing well shown by this figure. The lamp-pot e is thus placed low down in the lantern, so as to admit a free and uninterrupted current of air to the llame, and the curved tlange surrounding it protects the pot, while it also forms the bottom d ofthe lantern. The flange g, extending upward in continuation of the sides of the pot, gives support to the bottom of the globe. Holes through this vertical ilange admit air, and a hole, h, controlled by a sliding door, i, allows of the lighting of the lantern, this hole being in line with the slit in the burner, and there being in the bottom of the globe a recess,j, in continuation of the track or channel from the hole to the burner. The bottom of the lantern thus made up of the anges and lamp-potis attached to the lower part of the guard by spring-catches f, the outer ends of these catches, which pass over the lbar or rod of the guard, being shown projecting at 7c in the lower portion of the parts represented by Fig. 2, the thumb and nger-knobs m, with the interior part ot' the catches, being shown by Fig. 3.

This construction and arrangement of the parts of the lantern admits ot' easy handling of it and every facility for attaching and detacliing the several parts and the replacing of any broken o r injured piece, while it permits the removal ot' the lamp-pot and bottom as a whole, instead ofrequiring the two movements which have to be made when the bottom and the pot are ofindependentpieces and connected to each other as separate parts.

What Iclaim as my invention, and desire to secure by Letters Patent, is

1. The construction ofthe lamp-pot e, in connection with the flanges d and g, substantially as recited, allowing the guard to be attached to the bottom and the lamp and the bottom to be readily separated from the glass or globe and guard and dome, as herein set forth.

2. The hole h, with the sliding door z', in combination with the reoessj ofthe globe, for lighting of the. lamp, as herein recited.

This specification signed this 5th day of April, 1865.
