Comolele Specification Accepted, 14th Dec.. 1888
We JOHN BASSETT of Sherbourne Street Birmingham. in the County of Warwick
Plasterer and FRANCIS NAPIER SEYDE of Lonsdale Road Harborne in the County
of Stafford Gentleman, do hereby declare the nature of this invention to be as
follows:-
The object of this Invention is the construction of fire proof ceilings and partitions
in an economical and at the same time effective way and this is done in the following
manner.
In applying the Invention to ceilings joists being laid in the ordinary way
triangular strips are nailed on each side of the joists level with the bottom of them to
form skew-backs.and the nails which fix them are left projecting, or the strips may be
dispensed with and nails be driven into the joists and left projecting, boards are then
temporarily nailed to the underside of the joists and the spaces between the joists
filled in with cement concrete to a thickness of 2 or 3 inches. When this is hardened
sufficiently to hold together the temporary boards are removed and the under surface
plastered.
Thus the use of lathing is dispensed with and the joists sufficiently protected to
prevent them readily being affected by fire.
For partitions the nails are driven into the timbers as above described and the
spaces between them being plentifully filled in with cement concrete both sides can
be plastered and a completely solid partition constructed, thus dispensing with
double lathing.
With this construction of ceilings or partitioning a further saving is effected
through it not being necessary to place the timber so near together as in ordinary
work.

page_text: Improvements in the Construction of Fire Proof Ceilings and
Partitions.
We JOHN BASSETT of Sherbourne Street Birmingham in the County of Warwick
plasterer and FRANCIS NAPIER SEYDE of Longsdale road Harbourne in the County
of Stafford Gentleman, 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 :-
The object of this Invention is the construction of fire proof ceilings and partitions
in an economical and at the same time effective way and this is done in the following
manner.
In applying the invention to ceilings, the joists being laid in the ordinary way
triangular strips are nailed on each side of the joists level with the bottom of them
to form skew backs and the nails which fix them are left projecting or the strips may
be dispensed with and nails be driven into the joists, and left projecting; boards are
then, temporally nailed to the underside of the joists and the spaces filled in between
the joists with cement concrete to a thickness of two or three inches, in general.
practice it is found that from one to two inches in thickness is sufficient. When this
is hardened sufficiently to hold together, the temporary boards are removed and the
under surface plastered.
Thus the use of lathing is dispensed with and the joists sufficiently protected to
prevent them, readily being affected by fire.
For partitions the nails are driven into the timbers as above described and the
spaces between them fully filled in with cement concrete both sides can be plastered
and a completely solid partition constructed thus dispensing with double lathing.
With this construction of flooring or partitioning further saving is effected through
it not being necessary to place the timber so near together as in ordinary work.
We do not confine ourselves to the use of any particular description of cement but
prefer to use for the purpose cements which dry and set quickly.
Referring to the accompanying drawings

page_text: It will be readily seen that when the cement (d) or (i) has become hardened it will
be impossible for it to fall out in consequence of the strips (c) or (g) the projecting
portions of the nails (d) or (i) also assisting to form a key."
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The construction of ceilings and partitions without the use of laths by forming
them substantially as herein described with skew backs or with projecting nails
or both.
