page_text: I, MAX EULNER, of 15, Schimmelstrasse, Halle-on-Saale, Germany, Merchant,
do hereby declare the nature of this invention to be as follows:-
-
The object of the present claim is a soldering spirit lamp, with which by heat-
ing, with a wick impregnated with spirits, a recipient containing an absorbing
body also impregnated with spirits, we obtain a blow-pipe flame which may be
used for soldering metals, or for any other operation which necessitates a flame of
great caloric intensity.
The apparatus is composed of a hollow cylinder in brass, containing a wick of
a substance which easily absorbs spirits; this tube has its top and bottom closed
and to its lower end another tube is soldered serving as a handle socket. On
the exterior cylindrical side of the large cylinder a third tube is soldered con-
taining a wick impregnated with spirits, having its lower end closed and its upper
end exposed to the air.
A small opening is made in the side of the large cylinder, above the afore-
mentioned small tube, and whose height-reaches the middle of that of the large
cylinder.
If we light the wick of the small tube, the flame produced heats the larger
cylinder, a part of the spirits contained in the wick of this larger cylinder evapo-
rates and passes under a certain pressure, through the small opening made in
the cylindrical side of the larger cylinder, and is forced against the flame of the
small burner, thus forming the flame of the blow-pipe which may be directed as
we wish.
For filling the larger cylinder with spirits when it is exhausted it suffices to
plunge the lamp upside down into a recipient filled with spirits; the dried wick of
the larger cylinder will absorb the spirits, through the small opening, until it
is saturated.

page_text: to be performed, to be particularly described and ascertained in and by the follow-
ing statement:-
This invention has reference to improvements in soldering lamps and my inven
tion consists in a lamp constructed and acting substantially as hereinafter described.
In the accompanying drawing Fig. I. is a sectional and Fig. 2 a full side
elevation of one form of my improved lamp:
In carrying my invention into practice I employ. a tube or equivalent a closed
at the top and bottom ends by covers a¹ and containing a wick or other suitable
absorbent material b and the tube or vessel a has an aperture c for the purpose
hereinafter described.
At the side of the vessel a I provide a smaller vessel d also containing wick or
the like e but this vessel is open at its top end.
I also provide the lower end of the improved lamp with a tube / carrying a
handle i.
The action of my improved lamp is as follows: through the aperture & I intro-
duce suitable spirit or alcohol so as preferably to thoroughly saturate the wick or
other material b. I next also more or less saturate the wick e with spirit or alcohol
and having ignited the wick e the heat generated and impinging against the
vessel a will cause the spirit or alcohol within said vessel a to be converted into
gas which will escape at some pressure from the aperture c into the flame about
as shown at f in Figure II, and the said lamp will thus automatically act as a
soldering lamp and blow pipe until either the flame is extinguished or the spirit
or alcohol is exhausted.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
An improved lamp adapted to be used for soldering in which the blowing action
similar to that obtained from a blow pipe is automatically obtained by the heat
of the flame all for the purposes and substantially as described and illustrated.
