PROVISIONAL SPECIFICATION.
Utilization of Refuse or Scoria of Copper-smelting Furnaces as a
Grinding or Polishing Agent or as a Substitute for Emery.
I EDWARD ASKEW BATH of Southview, Sketty, near Swansea, in the County
of Glamorgan, Merchant, do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to utilize the refuse or scoria of copper furnaces as
a substitute for emery or the like, or to provide a polishing powder or polishing or
grinding stones or tools that shall be more economical than emery, whilst possessing
as great, or greater, polishing or grinding power.
In carrying out my invention I take the ordinary refuse or slag from copper
smelting furnaces and select therefrom the most suitable pieces or blocks and then
grind the same in any well known manner, afterwards sifting the powder so produced
through a fine sieve or sifter, or I may when the powder is required for delicate
purposes separate the finer from the coarser parts by elutriation, and for some
purposes the polishing or grinding powder is ready for use.
In forming polishing or grinding stones or other tools, I incorporate the powder
formed as before described with glue or any other suitable agent melted heated and
mixed with a solution of acid and methylated spirit, or with any other desirable
cement, the powdered substance having been previously heated, and the mass
is then thoroughly stirred together and transferred to suitably shaped heated
moulds, pressure being applied if found necessary. The moulds may then with
their contents be baked in ovens or if desired the contents may be removed after
partial baking in the moulds and further baked alone; when cool the stone or tool
is ready for use. I may sometimes mix the powdered slag or scoria with emery or
any other substance and use it either alone as a grinding or polishing powder or
mixed with other materials or cements and formed into wheels tools or the like as
above described; I may also coat linen or paper with glue or other adhesive
substance and sift or spread the powdered slag or scoria (or mixture of slag or
scoria and other materials) over the same whilst still adhesive, so as to produce a
substitute for emery or like cloth or paper.
