Improvements in and relating to Processes for Gilding.
I, OSCAR LIEPMANN, Manufacturer, of Konigs-Wusterhausen, near Berlin, in
the Empire of Germany, 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:-
This invention relates to mechanical devices for preparing and distributing the
liquid mediums necessary to affix gilding surfaces to mouldings, beadings or like
ornamental appurtenances.
This invention consists in an arrangement of jets fed by pressure from a vessel
in which the affixing liquid is contained and which play upon the moulding so as
to cover it with the necessary liquid, while rotary brushes or sponges in advance
of the jets evenly distribute the said liquid over the entire surface of the moulding
or beading previous to the operation of gilding all in the manner hereinafter
described.
At the present time the mouldings or beadings prepared by plane or otherwise
are submitted in their entire length to the gilding operations by first shellacing
and then covering with a thin layer of oil, the operation being conducted usually
by pencil brushes followed by a hand brush carried to and fro; and the object of
the present invention is to supersede this hand-labour, and while at the same time
increasing the efficiency of the work also decreasing its cost.
This invention is illustrated in the accompanying drawings as follows:
Figure 1 is a part perspective view of the brushes and jets in operation.
Figure 2 illustrates a further modification of that shown in Figure 1.
Referring to Figure 1 of the drawings a moulding such as a is fed forward at a
predetermined rate in the direction shown by the arrow, while nozzles d¹ d² d³ d'
from a supply tank, not shown, are arranged in number and position according to
the section of the moulding operated upon to throw liquid upon the beading just
behind the revolving brushes or sponges ww2. These revolving brushes rotate
in the direction shown by the arrows coiled about the shaft and are operated by
any suitable mechanism, and the contour of these brushes is so arranged that it
exactly fits the contour of the beading operated upon.
It is evident that as the beading is fed forward the affixing liquid will be con-
veniently distributed by the brushes, and it is also evident that rotating sponges
and brushes of a contour to suit the beading operated upon could be arranged in
series in conjunction with the necessary jets, so that the required number of liquids
should be distributed and arranged upon the surface of the beading previous to the
act of gilding.
Referring to Figure 2 of the drawings a beading a is also shown with jets dɩ
dd playing upon it, this beading a being of slightly different contour to that
shown in Figure 1. Brushes or sponges w¹³ are arranged to take into this
contour and as the beading is fed in the same direction and the brushes revolve
in the same direction as in the previous modification, it is evident that the affixing
will be evenly distributed over the entire surface of the beading which requires to
be gilded. In this modification a second revolving sponge m is shown which can

page_text: be used to apply colour, shellac or such like, and to work in combination with the
brushes w 102 situated behind it.
Let it be clearly understood that by arranging any number of jets and brushes in
such a way as to distribute any given liquid or powder over the moulded surface of
the beading, the whole operations of preparing the surfaces with affixing fluids,
and covering with colour, lac or metal dust, and polishing may be simultaneously
carried out.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
1. An improved process for gilding in which the beading moulding or like
article to be operated upon is fed forward at a predetermined rate in the path of
jets suitably placed which play upon it and distribute the affixing liquid or other
liquids and powders upon the part to be gilded, while revolving sponges and
brushes of suitable contour distribute the said liquid evenly over the prepared
surface, all substantially as and for the purpose hereinbefore described.
2. The improved process for gilding substantially as and for the purpose herein-
before described with reference to Figure 1 of the drawings.

3. The improved process for gilding substantially as and for the purpose
hereinbefore described with reference to Figure 2 of the drawings..
