Year: 1876

page_text: LETTERS PATENT to William Spence, of 8, Quality Court, Chancery Lane, in
the County of Middlesex, Patent Agent, for the Invention of "AN ANTI-
TARTARIC LUBRICANT." A communication from abroad by Isaac Bernhard, of
Paris France. Merchant.
Sealed the 8th May 1877, and dated the 14th November 1876
PROVISIONAL SPECIFICATION left by the said William Spence at the Office
of the Commissioners of Patents on the 14th November 1876.
WILLIAM SPENCE, of 8, Quality Court, Chancery Lane, in the County of
Middlesex, Patent Agent. "AN ANTITARTARIC LUBRICANT." (A communication
from abroad by Isaac Bernhard, of Paris, France, Merchant.)
The antitartaric materials or compounds hitherto employed have been found
defective not only with reference to the prevention of incrustation but also for
lubricating mechanical parts in contact with steam, the object therefore of this
Invention is to make a compound the elements of which will not affect metal, and
which shall unite the qualities of preventing incrustation and furnishing a lubricant
of the kind required. And the Invention consists in the manufacture of the
compound herein-after described :-
The component ingredients are one "kilogramme" (French measure) of any kind
of soap or saponified grease, one "kilogramme" of potato starch, meal, flour, or
ordinary starch, one "kilogramme" of ox gall or the gall of any other animal. And
the process of manufacture consists in melting or dissolving one "kilogramme" of
soap to fifty "grammes" (French measure) of gall. When the soap is melted or
dissolved a paste is made with the potato starch and nine hundred and fifty
grammes of gall; the whole is then mixed by means of heat. Any kind of meal,
flour, or starch may be employed, and in order to bind the material as required any
kind of glue may be used.
..
The antitartaric material obtained by the use and mixture of the above-named
substances prevents the formation of solid, deposits, whatever may be the materials
in suspension or dissolved in the water. The said material is capable of decomposing
and dissolving deposits previously formed, however hard or thick or of long
standing; it is also adapted for keeping clean the internal surface of boilers and
increasing their heating power.
The lubricating properties of the antitartaric material adapt it for preventing
wear of frictional surfaces of mechanical parts, such as slides, cocks, cylinders, or
pistons in contact with steam.

WILLIAM SPENCE, of 8, Quality Court, Chancery Lane, in the County of
Middlesex, Patent Agent. "AN ANTITARTARIC LUBRICANT." A communication
from abroad by Isaac Bernhard, of Paris, France, Merchant.
This Invention of "An Antitartaric Lubricant" consists in the manufacture of
the compound herein-after described.
The antitartaric materials or compounds hitherto employed have been found
defective not only with reference to the prevention of incrustation but also for
lubricating mechanical parts in contact with steam, the object therefore of this
Invention is to make a compound the elements of which will not affect metal, and
which shall unite the qualities of preventing incrustation and furnishing a lubricant
of the kind required.
The component ingredients of the compound are one "kilogramme" (French
measure) of any kind of soap or saponified grease, one "kilogramme" of potato
starch, meal, flour, or ordinary starch, one "kilogramme" of ox gall or the gall of
any other animal. And the process of manufacture consists in first melting or
dissolving one "kilogramine" of soap to fifty "grammes" (French measure) of gall.
When the soap is melted or dissolved a paste is made with the potato starch and
nine hundred and fifty grammes of gall; the whole is then mixed by means of heat.
Any kind of meal, flour, or starch may be employed, and in order to bind the material
as required any kind of glue may be used.
The antitartaric material obtained by the use and mixture of the above-named
substances prevents the formation of solid deposits, whatever may be the materials
in suspension or dissolved in the water. The said material is capable of decomposing
and dissolving deposits previously formed, however hard or thick, or of however
long standing; it is also adapted for keeping clean the internal surface of boilers
and increasing their heating power.
The lubricating properties of the antitartaric material adapt it for preventing
wear of frictional surfaces of mechanical parts, such as slides, cocks, cylinders, or
pistons in contact with steam.
Besides the economy of fuel, repairs, and grease obtained by the use of the said
antitartaric lubricant, it will be found in practice that the amount of work done by
machines the boilers of which are submitted to its lubricating action will be
considerably increased.
Having thus described the nature of the said Invention and in what manner the
same is to be performed, I hereby declare that what I claim as of the Invention
communicated to me from abroad as aforesaid is, the combination in or about in
the proportions herein-before stated of soap, of starch, or flour with the addition
of ox gall or other animal gall, and a glue of any kind and all kinds of gums.
In witness whereof, I, the said William Spence, have hereunto set my hand
and seal, the Fourteenth day of May, in the year of our Lord One thousand
eight hundred and seventy-seven.
Witness,
FRANK REDMAN,
