PROVISIONAL SPECIFICATION left by the said John Imray at the Office of

JOHN IMRAY, of No. 28, Southampton Buildings, Chancery Lane, in the County
of Middlesex. "IMPROVEMENTS IN THE CONSTRUCTION OF CEILINGS." [A com-
munication from abroad by Carl Stauss, of Cottbuss, in the German Empire.]
According to the present Invention, in place of using ordinary wooden laths for
ceilings, reeds or canes are employed which are by preference interwoven with
wires at distances apart. For this purpose according to one arrangement a layer
of closely woven reeds is first secured against joists or battens of the floor, and
upon this is secured a second layer of loosely woven reeds which may be of a larger
size; the interstices between these serve as a key for the plaster which is applied
in the usual manner, while the closely woven layer prevents the plaster from
penetrating farther than is necessary. The joists or battens to which the reeds are
fastened are by preference at distances apart corresponding to those of the wires with
which the reeds are woven, but if at other distances, then additional wires must be
stretched and secured where the joists or battens occur.
.
Instead of weaving the reeds together by means of wires, either the one layer or
the other, or both may consist of loose parallel reeds or canes. The woven layers
may be fixed directly to the joists of the floor above without intervening battens,
and there may be intermediate boards to afford additional support between the
joists.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Imray in the Great Seal Patent Office on the 17th March 1880.

According to the present Invention, in place of using ordinary wooden laths for
ceilings, reeds or canes are employed which are by preference interwoven with

closely woven reeds is first secured against the joists or battens of the floor, and
upon this is secured a second layer of loosely woven reeds which may be of larger
size; the interstices between these serve as a key for the plaster which is applied
in the usual manner, while the closely woven layer prevents the plaster from
penetrating farther than is necessary. The joists or battens to which the reeds are
fastened, are by preference at distances apart corresponding to those of the wires
with which the reeds are woven, but if at other distances, then additional wires
must be stretched and secured where the joists or battens occur. Instead of
weaving the reeds together by means of wires, either the one layer or the other, or
both may consist of loose parallel reeds or canes. The woven layers may be fixed
directly to the joists of the floor above without intervening battens, and there may
be intermediate boards to afford additional support between the joists.
Fig. 1 of the accompanying Drawings shews an inverted section, and Fig. 2
shews an underside plan of the before described improved construction of ceilings,
and Fig. 3 shews a part full size section of the same. A, A, is the inner layer of
small reeds or canes, woven closely together by wires and secured to the laths or
battens B by nails C, the laths being fixed to the joists D at distances apart
corresponding to the distances of the wires with which the reeds are woven
together, or they may be at double such distances. E, E, is the layer of larger
reeds or canes woven together by wires, and secured to the laths or battens B by
nails F, this layer of reeds is woven somewhat open so as to leave spaces between
the reeds through which the mortar G forming the ceiling passes so as to act as a
key. Instead of providing battens or laths on the undersides of the joists for fixing
the layers of reeds against, these may be fixed directly against the joists and
against the intermediate boarding H, which is for this purpose fixed somewhat
lower down.
Having thus described the nature of this Invention and in what manner the
same is to be performed as communicated to me by my foreign correspondent,
I claim,-
First. The use, for the construction of ceilings, of two layers of reeds or canes
secured, the one below the other, to transverse laths or battens, the upper layer
of such reeds being woven closely together while the under layer is woven open.
Second. Constructing ceilings of a layer of closely woven reeds or canes in
combination with open woven or unwoven reeds or canes to which the plaster
coating is applied substantially as herein described.
Third. In ceilings constructed of two layers of reeds or canes as set forth in the
preceding claims, securing the said reeds or canes to the joists and intermediate
boarding of the floor without the use of special laths or battens, substantially as
herein described.
In witness whereof, I, the said John Imray, have hereunto set my hand and
seal, this Sixth day of March, in the year of our Lord One thousand eight
bundred and eighty.
