manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—

chamber and conical tube, which consists in placing a tube outside the body of
the lanp, running from bottom to top of same, and entering the air chamber running
round it inside.
T'bis tube is for the purpose of conveying air to the chamber, and by turning
the tube inside the air chamber, in syphon form or otherwise to effectually prevent
accidents by liquid, running out of the lamp, should it happen to be overfilled and
upset, also completely isolating the inlet of air, to the air chamber from the light or
lights, making the lamp absolutely safe, when being carried about.
The following explains accompanying drawing.
A. lamp body.
B. conical tube.
C. air chamber.
D. central tube.
E. tube from bottom of body of lamp for the purpose of conveying air to chamber,
entering it, and running round it inside, in syphon form or otherwise, and terminating
with perforations at end. This entirely prevents the liquid coming out of the lamp
f overfilled, or tipped up at any angle, as it did through the air holes of Patent
No. 15,800, A.D. 1888, and isolating the inlet of air from the light or lights, and
making the lamp absolutely safe when being carried about.
