Improvements in Ceilings and Walls.
I, HEINRICH JANSEN, of Dusseldorferstrasse, 83 Duisburg on the Rhine, in
the German Empire, Master Plasterer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
The main distinguishing feature of the ceilings and walls represented in the
accompanying drawings is that a woven fabric, network, matting or plaiting,
such as g, made of textile fibres, or of rush, straw, or other vegetable material,
is retained in position by flat iron bars or rails s, or other suitable rails, and serves
to hold the plaster or other mineral matter which forms the surface of the wall or
ceiling.
In the erection of walls such bars are best arranged on both sides in alternate
succession, as is supposed to be the case in the example shown in the drawings;
the effect of this arrangement being, that the fabric, or plaiting, or equivalent, g,
is stretched at the same time at it is held in its place. In the case of ceilings, the
rails or bars s supporting the fabric or matting may be laid underneath,
between, or over the joists or binders, and may take an arched form, if desired.
In the drawings Fig. 1 is partly an elevation and partly a vertical section of a
wall embodying this invention; Fig. 2 is a horizontal section of the same; Fig. 3
is a vertical section of a ceiling; Fig. 4 is partly a plan and partly a horizontal
section of the same; Figs. 5 to 7 show a form of hook for holding and supporting
the flat bars or rails s; while Figs. 8 and 9 show a somewhat different form of
hook h.
Each nail or hook is provided with a head, wherein are formed one or more
slots, according as the nail is employed for holding one or more rails. These slots
serve for the reception of the edges, flanges, or projections of the said rails, which
they are shaped to fit. According to circumstances, one, two, or more such nails
may be employed in fastening each end of a rail or rod.
The head of the nail may have any convenient shape; for example, it may be
one-sided. The shank of a nail is made of a shape enabling it to be driven is to
the woodwork or masonry, or to be retained or locked therein; the rods being
covered over with suitable plastering or pugging, such as mortar or cement, and
being laid "on edge," when they will impart uncommon strength and rigidity to
the whole structure.
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:
-
held and
1. A wall or ceiling containing a piece of woven or plaited fabric
supported by flat iron bars s or rails, and serving to hold the plaster or other
material forming the surface of the wall or ceiling, substantially as described.
2. In walls or ceilings, chiefly composed of woven or plaited fabric and flat iron

page_text: supporting rails, nails or hooks h having slotted heads adapted to secure the said
rails to the woodwork or masonry, substantially as described.
