PROVISIONAL SPECIFICATION.
Improvements in Blow-lamps and Soldering-lamps.
We, ARTIDORO FARINETTI, Civil Engineer, and FERDINAND FRANCIS
ERNEST HEYSE, Merchant, both of 15, Secthing Lane, in the City of London,
do hereby declare the nature of this invention to be as follows:-
This invention relates to lamps used by house painters and others and by workers
in metals, and commonly called blow-lamps and soldering-lamps, and it consists in
the following construction:-The body of the lamp is composed of two adjoining
compartments adapted to receive oil or spirit or some kind of liquid. In the top of
the one compartment there is an aperture to hold a wick, and in the other com-
partment there is a tube which is directed towards the flame of the wick, and a
second tube to which an air blowing apparatus is attached, said air-blowing
apparatus consisting of a spray-ball operated by hand and adapted to force a
current of air through the liquid contained in the second compartment and carry
with it the gases of this liquid, blowing a stream of gas and air combined through
the flame of the wick, thus producing a long flame of great heat. Suitable
arrangements are provided whereby a copper bit can be attached to the apparatus,
so that the flame shall impinge upon it and be heated for the purposes of soldering.
A handle is attached at one end of the lamp to enable the user to lift it and move
it in any direction required.

COMPLETE SPECIFICATION.
Improvements in Blow-lamps and Soldering-lamps.
We, ARTIDORO FARINETTI, Civil Engineer, and FERDINAND FRANCIS
ERNEST HEYSE, Merchant, both of 15, Seething Lane, in the City of London,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to lamps used by house painters and others and by workers
in metals and commonly called blow lamps and soldering lamps.
In carrying out our invention we construct the body of the lamp with two
adjoining compartments adapted to receive oil, spirit or other kind of combustible
liquid. In the top of the one compartment we provide an aperture to bold a wick,
and in the other compartment a tube which is directed towards the flame of the
wick and a second tube to which an air blowing apparatus is attached, the said air
blowing apparatus consisting of an air or spray ball designed to be operated by
hand and adapted to force a current of air through the liquid contained in the
second inentioned compartment and carry with it the gases of this liquid so as to
blow a stream of gas and air combined onto the flame of the wick.
To enable our invention to be fully understood we will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a side elevation of a blow lamp constructed according to our
invention.

page_text: Figure 2 is a sectional elevation; and,
Figure 3 is a plan of the same.
a is the body of the lamp and b, c the two compartments, into which it is divided
for the reception of suitable oil, spirit or other combustible liquid.
lu practice we prefer to employ methylated spirit in the compartment b and
benzoline in the compartment e, the said liquids being introduced into their respective
compartments through openings closed by screwed caps d, d. e is the aperture in the
top of the compartment b for the reception of the wick which is supported in a
flanged tube g and is the tube directed towards the flame of the wick fand
connected to the compartment the latter being extended vertically at i and
provided with a horizontal tubular extension j into which a collar formed on the
tube is screwed, a leather or other washer being interposed between the said
collar and the end of the extension j to form an air tight joint. m is the tube also
connected to the compartment c to which tube the air blowing apparatus is attached
by the tube n the said tube m extending nearly to the bottom of the compartment c.
The blowing apparatus advantageously consists of a flexible air ballo (adapted to
he operated by hand) provided with the usual inlet and outlet valves p, q and an
elastic ball connected to the ball o and the tube n and serving as an air
accumulator, so that a continuous stream of air will issue therefrom notwithstanding
the pulsating intermittent supply of air forced therein by the ball o. s is a net
surrounding the ball to limit the expansion thereof in a well known manner.
t is the handle connected to the body of the lamp by the brackets u, u and formed
concave or hollow as shewn clearly in Figure 2 for the partial reception of the
ball o so that when gripped by the hand of the user the fingers serve to operate the
said ball. e is an opening at the top of the handle t through which the junction
tube between the balls o and passes and w is a cup or socket at the lower part of
the said handle for the reception of the lower open part a of the air ball o, an
opening being provided at the bottom of the said cup to allow air to pass to the
opening in the said part a. y is a screwed cap for screwing into the opening e in
the top of the compartment to cover the wick when the lamp is not in use.
By the herein-described construction it will be seen that (assuming the wick to
"be lighted) by operating the air ball o a current of air will be forced through the
benzoline in the compartment c and will carry with it the gas or vapour given off
from the said liquid, the said mixture of gas and air being directed onto the flame
of the wick by the tube thereby producing a long flame of great heat.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
-claim is :-
1. A blow or soldering lamp provided with two compartments adapted to hold
combustible liquid one of which compartments is provided with a wick tube whilst
the other is connected to au air blowing apparatus and provided with tubes
. arranged in such a manner that the operation of the said air blowing apparatus
directs a stream of gas and air onto the flame of the wick, substantially as
-described.
2. The manufacture and use of the improved blow or soldering lamp hereinbefore
described and illustrated in the accompanying drawing.
