I, GABRIEL SCHRÖDER, Manufacturer, of Winkelsfelderstrasse 58, Düsseldorf,
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 the production of certain kinds of ceilings, which are
provided with ornamental ribs forming geometrical patterns. Such ceilings are usually
produced by first making the plastered ground perfectly even and smooth, then
drawing on it the desired pattern, cutting laths or bars of plaster to the required
lengths and fixing them on the ground, so as to follow the pattern, so that the said
laths or bars form the projecting ribs. This process occupies much time and requires
experienced workmen.
To facilitate the production of such ceilings, so as to save time and expense, I
compose the ceiling of specially shaped plates or panels which form geometrical
patterns, each plate having a rim or flange which extends all round the edge and
forins patterns or ornamental ribs either alone or in conjunction with the adjoining
plates; the rim of one plate may overlap the edges of the adjoining plates, so that
there is no joint visible, or it may form a butt joint with similar rims of the adjoining
plates, and have half the width of the ribs, so that two adjoining plates or panels
form together a complete rib.
These plates or panels are fixed one after the other on the plain ceiling ground or
base, which has previously been made smooth, those in the middle of the ceiling being
preferably laid first.
In the accompanying drawings Figs. 1, 2, 3 and 4 represent variously shaped panels
or boards adapted to form ceilings according to my invention; Fig. 5 is a section of
the board shown in Fig. 4; Fig. 6 represents a ceiling composed of two kinds of
boards, such as shown by Figs. 1 and 4; Fig. 7 represents a ceiling composed of three
kinds of boards, such as shown by Figs. 1, 2 and 4, and Fig. 8 a ceiling composed of
three kinds of boards, such as shown by Figs. 1, 3 and 4.
Instead of crosses, squares, triangles, and stars, as shown, or in addition to the same,
other elementary figures may be used to form the boards or plates which compose the
ceiling according to a given system, and by suitable combinations of elementary figures
a great variety of patterns may be produced. The surface of each board between the
rims may be plain and smooth, or it may be ornamented in any convenient manner,
and one or more of the boards may be distinguished from the others by its shape
or ornamentation, for instance, the board which is intended for the centre of the
ceiling.
After the boards or plates have been fixed to the ceiling ground, no further labour
is required, except in some cases to fill up or smoothen the joints between contiguous
boards. The boards are preferably made of plaster of Paris, with or without the
addition of other suitable materials.

page_text: 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. A ceiling composed of flanged boards of different shape, so that the flanges or
rims of adjoining boards fit together and form ornamental ribs or patterns in relief,
substantially as described.
2. The manufacture of a ceiling by making boards or plates provided with rims
all along their edges and of different shapes, but so as to form a system, and
then fixing the said boards to the ceiling ground one after the other, so that the
rims of adjoining boards form together ornamental ribs, substantially as described.
3. Ornamental ceilings composed of flanged boards or plates joined together, so
that their rims form patterns in relief, substantially as described and shown."
