Letters; Patent Nb. 86,549, dated .Februar/ry 2, 1869y i i IMPROVEMENT IN LANTERNS.
The Schedule referred to in these Lettera Patent and making pari: of the lampe.
To all whom it may concern.'
13e it known that I, JOHN H. IRW1N,ofChicago,in y
. ence being had to the accompanying drawings, and the letters and figures marked thereon, which form part of this specification.
My said invention relates to lanterns having tubes extending from a funnel-shaped top to the base of the lantern, whereby the heat of the flame of the lamp, rising into said funnel-shaped top, produces a current of air down through said-tubes, so as to supply the burner with oxygen to support the flame; and
It consists in a novelarrangement in the said funnel to gat-her the air, iso-canse it to enter said tubes, for the purpose above mentioned; and v d It also consists in a novel arrangement, whereby the topof the lantern, which holds the upper end of the globe, can be moved or adjusted up and down,'to permit the said globe to -be removed and replaced, when desired, as hereinafter more fully set forth.
To enable those skilled in the art to understand how to construct and use my said invention, I will proceed to describe the same with particularity, making refer,-
ence, in so doing, to-the aforesaid drawings, in which- Fgure l is a central vertical section of my improvemeut;
Figure 2 is a side vieW thereof; and Figure 3 is a bottom view of the funnel aforesaid,
f 4with its attachments.
Similar letters of reference in the several figures'dente'the same parts of my invention. fri -A represents the oil-pot of the lantern, which is sur- The said inverted funnel E is provided 'with a collar,
fitting upon a vertical tube, D, which tube branches out and forms theaforesaid tubes -C O, as shown.
Surrounding said tubeD, resting upon the collar of E, and against the shoulders formed by the tubes C,
is a spring, S, which serves to press down the funnel E,` and thus holds the ling F close down upon and over the top ofthe globe, to hold the globe securelyjn place.
At the same time, when it is desired to remove the globe, 'the said spring will yield, to permit the 'ring F to be raised up from the globe for that purpose.
The aforesaid tube D projects throughy lthe funnelplate E, and is provided with an inner or secoud'fun- Anel or ange, b, which serves the samepurpose, to a certain extent, as the outer flange E, and also prevents the funnel-plate or liange E from being forced on" from the tube by the spring S.
"The heat of the burner, rising, creates a current of l air, through the tubes G, into the burner, while fresh air is admitted through-the perforated plate H, which rises near the glass, forming a shell of cold air next to the glass, angl preventing the heating of the same, androf the metallic top,and, at the same time, mingling with the descending current in the tubes C C, to supply the dame.
One feature in a lantern of this construction is that 'it is a self-regulator, and if the wick should be turned up too high to cause,the same to smoke, the elfect of such condition upon the air-.currents 'supplying the flame with oxygen is to subdue' and reduce the cornbustion, so that it shall not smoke. y
The flanges E b, provided they be arranged above the liauge or ring F, so as to leave a horizontal `unobstructed passage between them and-the said lring F,
'or thetop of the globe, cause the wind, 'blowing laterally against the lantern, to pass upward into the tube D, assisting the aforesaid currents' in the tubes C Q, instead of blowing downward into the globe, which would'be the case if said flanges E t, o r one or Inore of them, were not used, or were arranged Within and below the top of the globe.
Having described the construction and operation of my invention, I will specify what I claim, and' desire to secure by Letters Patent.
1. I claim the arrangement, beneath the funnelplate E, of the prolonged tube D, and one or more tlanges l), arranged substantially as and for the purposes set forth.
2. I claim, in combination with the ring F, funnelplate E, aud tube D, a spring, S, arranged to operate in the manner and for the purposes specified.
