An Improved Apparatus for Soldering.

page_text: An Improved Apparatus for Soldering.
We, PHILIPP HEINZ and JOHANN HEINZ, both of Pforzheim, in the Grand Duchy
of Baden, Germany, Factory Proprietors, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improvement in soldering-lamps.
Hitherto such soldering-lamps have only been so constructed that during the
soldering process a cock which conducts the gas being used stands open until all
the soldering work is done.
But such soldering-lamps have this disadvantage that through their employment
very much gas is irremediably wasted.
The subject of our invention is our having hit upon a contrivance for soldering-
lamps which not only exactly regulates the supply of gas according to the need,
during soldering work, but, self-acting, also shuts it entirely off so soon as the
solderer from any cause no longer serves the blow-pipe with air.
The invention consists in the arrangement of a contrivance for shutting off gas
regulated by the atmospheric pressure of. the blow-pipe.
In the accompanying drawing, where the same letters denote the same parts,
Figures 1 to 3 show one view and two longitudinal sections of the contrivance
which forms our invention.
Figure 4 shows a treadle bellows such as can be brought into connection with
a blow-pipe in the case of larger soldering-lamps.
The main point of our invention consists in this, that we provide a blow-
pipe (A) Figure 3, with a branch (a) and bring this branch into connection with
a receptacle (C) of the soldering-lamp by means of an elastic tube or hose (B).
In this receptacle is an india-rubber body (D), which can be lengthenedi out like
a concertina by the letting in of air pressure. Through its expansibility this
body can act on an angle-lever (E) whose top (E1) is rotary. The attachment of
a spring or of a weight (e) which moves radially on its shank, causes the second
arm of this lever to continually compress the rubber body (])).
Concerning other parts of our invention, the angle-lever (E) is fixed with its
top (E1) on an angle (F) Figure 2, which last having bearers at (G) on the
opposite side of the apparatus within a casing (H) by means of a lever (J) fixed on
the axle (F) opens a valve (K) according to the measure of the expansion of the
body (D) or, in other words, according to the pressure of air which takes place,
and also wholly shuts off the gas being used when this air pressure ceases, so
that the small pipe (L) which feeds the flame only remains as long in action as
the soldering work lasts. As well by turning the gas-cock at the joining pipe
of the soldering lamp this flame is extinguished.
The small feed-pipe of the flame is thus in open connection with the gas-
holder (H).
In the case of larger soldering-lamps the use of a treadle bellows (M) Figure 4, is
Such a bellows sends through its hose (N) to the blow-pipe-which

same way regulating the consumption of gas.
From the Figures 1 to 3 it can be easily also seen that with the increase of air
pressure in the blow-pipe (A), which assures the accomplishment of a greater
amount of soldering work, the valve (K) is opened wider whereby more gas can
issue from the bulb (P) than when in fine soldering work only a small current
of air is needed and the valve (K) is only a little opened by (I).
The use of this soldering-lamp is exactly similar to that with lamps of such a
class as have been hitherto employed.

PHILIPP HEINZ and JOHANN HEINZ, of Pforzheim, Grand Duchy of Baden,
Germany, Merchants, 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 an improvement in soldering-lamps. Heretofore such
soldering-lamps have only been so constructed, that during the soldering process
a cock which conducts the gas being used stands open until all the soldering work
is done.
But such soldering-lamps have the disadvantage that through their employment
very much gas is irremediably wasted.
The subject of our invention is our having hit upon a contrivance for soldering-
lamps which not only exactly regulates the supply of gas according to the need
during soldering work, but self-acting, also shuts it entirely off as soon as the
solderer from any cause no longer serves the blow-pipe with air.
The invention consists in the arrangement of a contrivance for shutting off gas
regulated by the atmospheric pressure of the blow-pipe.
In the drawing accompanying my Provisional Specification where the same
letters denote the same parts
Figure 1 to 3 show one view and two longitudinal sections of the contrivance
which forms our invention,
Figure 4 shows a treadle bellows such as can be brought into connection with
a blow-pipe in the case of larger soldering-lamps.
The main point of our invention consists in this that we provide a blow-pipe (A)
Figure 3, which blow-pipe may have a mouth-piece with a branch (a) and bring
this branch into connection with a receptacle (e) of the soldering-lamp by means
of an elastic tube or hose (B). In this receptacle is an india-rubber body (D) which
can be lengthened out like a concertina by the letting in of air-pressure. Through
its expansibility this body can act on an angle-lever (E) whose top (E 1) is rotary.
The attachment of a spring or of a weight which moves radially on its shank,
causes the second joint of this lever to continually compress the rubber body (D).
Concerning other points of our invention, the angle-lever (E) is fixed with its
top (E1) on an axle (F) Figure 2, which last having its bearings at (G) on the
opposite side of the apparatus within a casing (H) by means of a lever (I) fixed on
the axle (F) opens a valve (K) which shuts off the gas being used according to
the measure of the expansion of the body (D).
The small pipe (L) which feeds the flame only remains as long in action as the
soldering work lasts, and is in open connection with the gas-holder (H).

page_text: In the case of larger soldering-lamps the use of a treadle bellows (M) Figure 4.
is recommended. Such a bellow sends through its hose (N) to the blow-pipe-which
can then be freely handled-the requisite quantity of air while always in the
same way regulating the consumption of gas.
•
From the Figures 1 to 3 it can be easily also seen that with the increase of air-
pressure in the blow-pipe (A), which assures the accomplishment of a greater
amount of soldering work, the valve (K) is opened wider whereby more gas can
issue from the bulb (P) than when in fine soldering work only a small current of
air is needed and the valve (K) is only a little opened by (I). The use of this
soldering-lamp is exactly similar to that with lamps of such a class as have been
hitherto employed.
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:-
.
The combination of a soldering-lamp working with a blow-pipe (A) having a
branch (a) and tube (B) fixed to the soldering-lamp and connected with a rubber
extensible hollow drum (D) resembling the bellows of a concertina, which drum (D)
when extended can, by means of an angle-lever (E) acting at a slight pressure,
give a partial rotation to an axle (F), joined to a lever-arm of said axle being a
valve (K) which regulates or shuts off the egression of the gas to the soldering
flame according as the pressure of air blown into the blow-pipe varies or ceases
altogether, substantially as described.
