A New or Improved Compound for Use in Welding, Tempering, and
otherwise Treating Metals.
I, CECIL URQUHART FISHER, of 1 Furnival Street, Holborn, in the county of
Middlesex, Engineer 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 :-
The object of this present invention is to provide a practical compound of superior
efficiency for the convenient use of blacksmiths and other metal workers for the
purposes of welding, tempering, and refining steel, and for correcting and restoring
to proper condition the quality and life of steel which has been burned or overheated;
also to provide a compound or composition of matter for the purposes stated which
will not deteriorate and become practically useless by standing for a considerable
length of time or under the ordinary conditions of exposure. These objects are
attained by a composition formed of ingredients combined as hereinafter describod.
For producing this improved welding compound, the following named substances
as ingredients are employed and combined in the proportions specified, although some
variation of proportion may be permitted without materially changing the nature
thereof, viz. borax, sixteen parts by weight, sal ammoniac one part, carbonate of
iron one part, and plaster of Paris, four parts.
In making this compound the borax is first heated in an open pan or vessel over a
slow fire, to drive off a considerable portion of the water of crystallization, then the
sal ammoniac together with the carbonate of iron and the plaster of Paris are added
and the mass is thoroughly mixed and exposed to a gentle heat until it is dry. It is
then cooled and comminuted or pulverized by grinding to a finely-powdered form
in which condition it is put up in packages ready for the market and use.
When used, the powdered compound is sprinkled upon the surface of the steel to be
welded or forged, the metal having been previously leated to a red-beat in a manner
similar to the processes heretofore employed.
This compound is also very useful for the purpose of welding cast steel and also
for correcting or restoring to proper condition steel that has been overheated or burned
and for giving renewed life and quality to drills, stone-dressing tools and similar
tools that have been injured in heating and tempering.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A compound for the purpose of welding, toughening and refining steel, consisting
of borax, sal ammoniac, carbonate of iron and plaster of Paris in combination sub-
stantially as herein before set forth.
2. A compound for use in welding, refining, or treating steel, composed of borax,
sal ammoniae, carbonate of iron, and plaster of Paris, combined in the proportions
substantially as specified and prepared in the manner substantially as described.
