Improvements in Apparatus for Soldering and other Purposes.
I, GUSTAVUS ADOLPHUS JOHN SCHOTT, of Westend Mills, Richmond Road,
Bradford, in the County of York, Manufacturer, 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 that class of apparatus by means of which a current of
air is driven through a flame, which is directed upon an object, for the purpose of
soldering or fusing it and similar purposes.
The object of this invention is to provide a simple, inexpensive and convenient
apparatus or lamp for these purposes, in which a current of air is employed for
dividing into spray petroleum or similar oils, which when intermingled with the
current of air and lighted, produces a jet of flame of great heat and purity at very
slight cost.
will describe the invention with reference to the accompanying drawings, Fig. 1
of which represents my improved apparatus partly a front view partly in section
and with some portion of outer coverings broken away in order to show interior
arrangements.

The current of air may be produced by bellows, an air pump or any other con-
venient means, and is conveyed through a flexible tube attached to the end "a"
of the metal tube "i" which is provided with a tap "a" at one end and a fine
pointed nozzle "b" at the other, which stands at a right angle with another similar
nozzle ""attached to one end of a metal tube "k," the other end of which is
provided with a strainer "y," which may consist of fine wire gauze or other suitable
material, and reaches to near the bottom of the oil reservoir "h," which has an
aperture, which can be closed by a screw plug "," and through which the reservoir
is filled. When by opening the tap a the current of air is caused to issue
from the nozzle "L" and blow over the nozzle "" it thereby sucks up the oil
from the reservoir, which issues from "7" and is carried along with the current of
air in the form of spray which enter the conical tube or hood "c," drawing with
them a considerable part of the surrounding atmospherical air, and on the oil
spray or vapour being lighted, it burns with intense heat owing to the large amount
of oxygen supplied in this manner to the flame, which is from 4 to 6 inches long
and issues from the small end of the hood " ," which is mounted to pivot round a
stud fixed at "" to a supporting frame ". m to which are also suitably attached
the tubes "k" and "i" before mentioned and a set screw e "which supports the
cone "e" and serves for regulating its position in a vertical direction with reference
to the flame.

When the cone 66

colour perfectly free from soot and at its maximum of heat of about 1300 degrees
Celsius (Centigrade). The flame showing a yellow colour is a sign of the cone
not being in the proper position, which must be adjusted by means of the set
e as before mentioned.

The cone "e can be turned upwards a quarter of a revolution round its pivot,
so as to allow of free access to the nozzles "" & "," which are arranged to be
easily detacheable by screwing from their respective tubes for the purpose of being
cleaned out when necessary. The immersed end of the tube "k" is provided with
a strainer as before mentioned, so as to prevent. impurities from stopping up the
nozzle "" and it is advisable, that the air admitted into the tube "i should also

reason.
In Fig. 2 is represented a suitable and, convenient bellows for use with my
improved apparatus, consisting of the pair of bellows "x," made of india rubber,
which are placed upon an iron frame"y" to which is hinged the treadle "z" for
the foot of the operator, who can thus conveniently work the bellows, whilst having
his hands at liberty for manipulating the lamp.
Having now particularly described and ascertained the nature of. the said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an apparatus' for soldering and other similar purposes the combination of a
reservoir "," with a 'tube "k," strainer "g" and detachable nozzle" "/" sub-
stantially as and for the purposes specified.

2. In an apparatus for soldering and other purposes the combination of a tube "i"
with a tap 66 α and a detachable nozzle "b" and with or without a bellows "
frame "y" and treadle " z" substantially as and for the purposes set forth.
3. In an apparatus for soldering and similar purposes the combination of a
moveable hood or cone с and set screw "e" with nozzles "b". for delivering a
current of air, and "1" for delivering oil spray substantially in the manner and for
the purposes set forth.

4. The general arrangement and combination of parts constituting the apparatus
for soldering and other similar purposes substantially as hereinbefore described' and
illustrated in the accompanying drawings.
