COMPLETE SPECIFICATION.
A New or Improved Soldering Iron.
I, FREDERICK GEORGE CAVE, of Fenny Stratford, in the County of Bucking-
hamshire, Brewer, 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 :-
My invention relates to a new or improved soldering iron as used by tinmen, plumbers
and others, and is constructed upon the principle of a goffering iron, that is to say,
the copper bit is screwed or rivetted upon or into one end of a copper or other
metallic tube, and is heated by inserting within the said tube a hot iron core, and
connected to a suitable adjustable handle by the means of a band surrounding the
said tube and terminating in a pair of spring jaws through which a bolt passes
engaging with the end of the handle, and by the aid of a fly nut or its equivalent,
screwed upon the said bolt, the band is caused to grip the tube and hold the handle
at any desired angle.
My invention is designed to attain the following objects and advantages,
First. The copper nosing or bit when once cleaned and properly tinned remains.
so for a very lengthy period, and does not require to be frequently thrust into a
block of sal ammoniac or its equivalent to keep it in this condition, as hitherto, for
the reason, that the said bit being heated by the insertion of the heated core is not
exposed to, and does not become burned or oxidized by, being brought in contact
with a coke or other fire as hitherto, thereby materially prolonging the life of the.
bit. Second by reason of the handle being adjustable to any angle relatively to
the nosing or bit, the workman is enabled to reach therewith places and parts of his
work not come-atable by any of the soldering irons hitherto made and used, and by
reason of the handle not having to be thrust into the fire with the bit, and
further, by reason of the said handle not being integral with the bit, but swivelled
thereto, the path of conductivity is broken, and the handle remains comparatively
cool even after long use, whereby I am enabled to employ a handle of less length
than hitherto, and consequently lighten the weight of the tool in the workmans
hand. Third, by having two or more cores to fit the one tube or case,
the spare
ones may be in the fire getting hot while the one is in use, and as these do vot
deteriorate by being kept in the fire until wanted, they may be allowed to get red
hot if convenient, thereby saving the need of the workman having two bits in use
upon one job or losing time while waiting to heat his bit if one only be in use.
In the accompanying drawings
Fig. 1 is a longitudinal section of my improved bit with part of the handle
broken away.
Fig. 2 is a cross section of same upon the line A. B.
Fig. 3 is an end view of a core or heater illustrating (as hereinafter explained)
the manner of retaining this within the tube or case.
Fig. 4 is a side view of the said soldering iron with the core partly withdrawn
therefrom and the handle broken away.
I carry my invention into effect by constructing of copper, iron, brass or other
metal, a short length of tube A, to one end of which I attach by screws, rivets or
pins a copper nosing or bit B, partly hollowed out to receive the nose of an iron
core C, when this is heated and placed within A as shewn in Fig. 1. The case or
tube A is surrounded transversally by a metallic clip D, the jaws of which a, b,
receive the head E of a handle F, through which, and the said jaws a screw bolt G,
is passed and receives a butterfly or other suitable nut H, which, when screwed firmly
thereon, serves the double purpose of causing the clip D, to grip the tube A at any

page_text: part of its length, and firmly hold the handle F, at whatever angle the nature of
the job may require, or the workman may find most convenient, this having the
range of a full half circle as shewn by the dotted outline thereof in Fig. 1.
The core C is provided at its outer end with rim c, a portion of which is removed
or flattened at c', (shewn more graphically at Fig. 3) in order that when C is placed
in A this may clear a hooked projection J, fixed upon A, but if then C be partly
rotated, the rim c thereof will engage with J, as shewn in Figs. 1 and 3, and upon
the withdrawal of C the same part rotation is necessary to enable e' to clear J; as
shewn at Fig. 4. A suitable eye or loop K is formed upon, or attached to C, to
permit this to be handled and manipulated as stated by the aid of any suitable tool
or wire having a hooked end capable of engaging with and rotating the same.
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 :-
First. The construction and use of the herein described soldering iron, and the
several parts constituting the same, connected, combined and operating substantially
as and for the purposes herein set forth and shewn by the accompanying
drawings.
Second. In an improved soldering iron, the combination of a copper or other
metallic case or tube A screwed or rivetted to a copper nosing or bit B, constructed
to receive an iron core C, provided with an eye or loop K and rim c, flattened at c¹,
the latter for clearing a hooked projection J, connected to A, the former for
engaging therewith when C is placed in A. The clip D surrounding A, provided
with jaws a, b, receiving the head E of a handle F, with screw bolt G passing
through a, b, and E, provided with a suitable nut H the tightening of which fixes D
upon A and the handle F at any desired angle, substantially as herein described
and shewn by the accompanying drawings.
Dated this 6th day of February 1894.
