COMPLETE SPECIFICATION.
An Improved Polish for Articles of Iron, especially Stoves and Grates.
WILLIAM TIEDEMAN 22 Bandon Road St. James Road Victoria Park in the
County of London Commercial Clerk 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 preparation can be made and used both in a liquid and paste form. The
application in both cases being very simple by means of a brush or cloth and polished
off in the usual way with an ordinary stove brush.
In carrying out my invention a solution of gelatine and glycerine is first made by
dissolving double size in diluted acetic acid (vinegar) of the strength of not less
than 4% of real acetic acid. (The diluted acetic acid to be heated sufficiently
to thoroughly dissolve the size.) The proportions used are, one part of size to three
parts of the diluted acetic acid and to every quart of this compound are to be added
1 oz. of glycerine oz. vegetable black and oz. of nitro benzole. The mixture
thus formed is set aside to thicken, the time required for this operation depending
upon the temperature at the time of manufacture. At a temperature of about 50° F.
a very short time say one or two hours would suffice but at a higher temperature
a longer time is required. This thickening is not absolutely required for the
efficacy of the polish, as by a little shaking of the bottle the different ingredients
become sufficiently amalgamated for use. As soon as the mixture begins to thicken
there is added with as little stirring as possible, but sufficient to well intermingle
some plumbago with the gelatine solution, in the proportion of lb. (more or less
according to quality) of blacklead (plumbago) to every 3 lbs. by weight of the
gelatine solution.
To form a paste two parts by weight of diluted acetic acid is used with one of
size with the same proportions as before stated of glycerine nitro benzole and
plumbago, and to give greater consistence for putting up in boxes there is added
oz. of vegetable black to every 1lb. of the mixture.
The above proportions are approximately given and are subject to variation
according to the strength and quality of the ingredients used.
The advantages to be derived from the use of the polish are-That in addition to
brilliancy it imparts greater depth of colour than the blackleads ordinarily in use.
That it saves time and is more cleanly when in the users hands being immediately
ready for use and requiring no moulding, breaking, powdering or mixing as with
ordinary blackleads in blocks or cakes. That its fragrance makes its more pleasant
in the using than is the case with ordinary blackleads.
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-
1. The invention of an improved polish in a liquid and paste form for articles of
iron especially stoves and grates and that such polish is composed of the
ingredients and proportions hereinbefore stated in the Specification.
2. The sole right to manufacture and use the same either in a liquid or paste form
or in both forms.
