Improvements relating to the Marbling of Enamelled Articles, and
to Apparatus therefor.
GUIDO GNÜCHTEL of Lauter Saxony, in the Empire of Germany Manufacturer
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 the marbling of enamelled articles and to apparatus
therefor.
Household and kitchen utensils and other articles have heretofore in the
enamelling been marbled by coating the article with a thin white (or coloured)
layer of enamel, next squirting coloured (or white) drops upon this layer and then
shaking the article moderately. By this shaking the enamel squirted on to the
ground is distributed in such a manner that only veins remain visible of the said
ground.
This method does not permit of a uniform marbling, and very great skill is
moreover necessary for carrying it into practice.
The aforesaid defects are obviated by the method which forms the subject of my
invention; which differs from the methods hitherto employed by the fact that the
covering enamel is not squirted on to the ground, but is applied to the same by
means of a plate provided with pins or bristles, in such a manner that the drops
formed at the points of the pins or bristles will be deposited upon the said
ground.
The operation of depositing the drops upon the ground is continued until the
latter is entirely covered with drops of uniform size, whereupon I knock gently
In this manner
against the article for the purpose of causing the drops to run out.
I obtain a uniform marbling which produces a pretty effect.
No great skill is required for carrying this method into effect, so that any
workman may do the marbling.
The apparatus used for applying the covering enamel may consist of a plate
provided with a handle or knob, and which carries on one side one or more rows of
pins or bristles which are preferably made of approximately equal length.
In the accompanying drawing
Figure 1 represents a side elevation of such an apparatus, and
Figure 2 a view from below.
A plate a is provided with a handle or knob a', and pins bare secured to the said
plate and arranged longitudinally in four parallel rows.
According to the distance between the pins or bristles the marbling will be
coarser or finer.
It may be observed that neither of the two layers of enamel need be white, as
both layers may be coloured but in this case the colours must be different.
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. A method of producing a uniform marbling on enamelled articles, which
consists in depositing upon the ground provided on the article drops of an enamel
having a different colour by means of pins or bristles which have previously been
dipped into the covering enamel, and which may be secured in one or more rows to
a plate or bar.
Second. For carrying out the method described in the first claim the employment
