' Letters Patent No. 100,57-8, dated,v March 8, 1870.

The Schedule referred to in these LettorsPatent' and making part of the same.

Toa'll afhom t'tmay concern Be it known that I, ARNOLD WITHMAR, of St. Louis, inthe county lof St. Louis, and State of Missouri,` have inventeda new and useful Improvement in Lanterns; and I do hereby declare that the following is va full and true description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon. v Inmy improved lantern it is my purpose `to avoid theuse of a globe, such as isv usually now employed to shield the flame, substituting'therefor an ordinary so-called coal-oil-lamp'v chimney. This is purchasable at every `country `or Itown store, whilst the globes are not such stock in ordinary trade.'

With-regard tothe application of the usual cylindrical rand truncate-ended chimney to my said lantern, and 'with regard to the' actin thereof to give a good and especially a steady light, when said lan- .tern is carried in the open air, and subject to gusts of wind,this invention relates to the arrangement of the lower draught-holes above' the bottomof the glass,

so that direct ingress of ainto the ame is avoided,

and similarly, the top draught or ventilation` holes' are below the upper. edge of the truncated end of 'the glass` "i Lastly, as the .glass in this arrangement'extends x below the axis of the usual wick-shalt and wheel, I

have arranged to operate the wick by a ratchet-'wheel and suspended pawl from below, thusv avoidingr the cutting ofthe glass.

To enable those herein skilled to make and use my said invention, `I will now more fully describe the same, referring herein-to the accompanying- Figure 1 as a sectional elevation, to

Figure 2 as a side view'with -lower parts removed.

A is the usual lantern base or foot; hereupon is the iron fender B, supporting. the top ring C with the usual bail attachment.

Near the upper edge of the base A are the draughtholes c, through which the main volume of air passes to feed the flame. v

Ou its inner surface thereare secured to said base A the spring chimney or globe-rests a', upon which the chimney or globe D is placed and is held.V

Said globe, as indicated inthe figures, Vdoes not ap proximate to the usual spherical globe'now used on lanterns, but the same is the, usual coal-oil lamp chimney. 4

As the bottom edge d of said chimney is considerably below -the line of the openings ct, no direct gusts of wind can pass with such violence to the flame as to Adisturb it.

4pass through the chimney D, I avoid this byam'anging a ratchet-wheel,' F, on the end of said shaft, and

suspend from said shaft the pawlgcarrier f and f', ex-

tending nearly to the bottom of the lantern by holding the lantern up and operating the pawl properly, the wick may then be suitably regulated.

The cap G its within the top ring C this has an upper conical part, g, with perforations y1, these are below the upper end of the chimney D, thus again avoiding direct blasts of wind.

In' order to furnish an outlet for surplus air, which may enter or be in the cap G, I arrange said cap with a cyliudli'cal base, Gl; this passes down Within the top ring O, and has the serrated ends yz, which rest on the chimney D. Between the ends g2 the angular openings g3 act as rel-iet' openings for confined'air in the cap G, as aforesaid.

The chimney D will thus at its upper end be held by the prongs g2, and an air-chamber will be created between the chimney D and said cap, and said airchamber has the exits gl and g3. v

` The cylindrical base. G-1 of the cap and the top ring O, instead of being made to it or slide within each other, as` shown in the .figureamay furthermore be arranged with screw-threads, so that thel same maybe more securely attached if desired. Y

.'In order to prevent the heat of the flame from too strongly heating the cap G, I have arranged within the same the inner cap G2, as shown in Iig. 1. Said inner'cap also acts to prevent the heat from striking the hand of the user in carrying the lamp about when used.

Having thus fully described my invention, What I claim is- 1. The chimney D, 'combined with the cap G Gl G2 andthe openings g1 and g3, arranged in relation to' each other and the chimney substantially as and for the purpose set forth.

2. The lantern described, consisting essentially of the base A with rests et', removable chimney D, draught-holes a, oil vessel E and cap G Gl with openings g1 g, when constructed andarranged as described,

Afor the purpose set forth.

In testimony of my said invention, I have hereunto set my hand, in the presence of ARNOLD WITHMAR. Witnesses: A CHRISTOPH KNICKMEYER, WILLIAM W. HERTHEL.
