Improved Fireproof Floors:
FREDERICK HINTON 50 Kilton Street Battersea Park Road London,
Carpenter and JAMES DAY 451 Battersea Park Road Carpenter do hereby
declare the nature of this invention to be as follows:—
This invention is intended for the purpose of constructing fireproof floors, consisting
entirely of wood. The method of construction is as follows, ordinary joists fixed
in the usual manner, the distance between each joist may be from 9 to 14 inches,
joist next wall in all cases to be firmly bedded in mortar, the spaces between joists
to be filled in solid with wood blocks of any thickness from 2 inches upwards, the
blocking to be 5 inches deep, the under side to be level with bottom edge of joist,
in all cases the blocks must be fixed with the grain vertical, each block to 'be
prepared with a groove on each edge to receive in. x in. fillet which shall be
fixed on each side of every joist for the purpose of carrying blocks, the top edge
of fillet is to be 3 inches from bottom edge of joist.
The blocks are also to be prepared with a further groove on each side to receive
when being fixed a tongue 1 in. x in. the top side to be 3 inches from bottom
edge of joist, this groove and tongue will be horizontal, and is for the purpose of
making the floor completely air tight from the ceiling below to the top of the floor
above.
.
Fireplaces may be treated in the same manner, at the same time conforming with
the present bye laws for buildings.
A floor constructed in this manner would be absolutely air tight and fireproof.

We, FREDERICK HINTON and JAMES DAY, Inventors of 50, Kilton Street,
Battersea Park Road, London,.S.W., 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 object of our invention is to construct an air tight fireproof floor entirely
of wood which shall at the same time conform to the provisions of the bye laws
and regulations now required to be observed by builders and others.
In carrying out our invention we construct a floor as follows:-The joist next
or against the wall in all cases being first firmly embedded in mortar or any other
euitable fireproof material, the remaining joists are placed parallel to each other
as usual at intervals preferably from nine to fourteen inches apart. The spaces
between the joists are filled in solid with wood blocks of any thickness, say from
two inches upwards, the blocking being preferably five inches deep and fixed so
that the underside is Hush with the bottom edge of the joists. The said blocks

cases the blocks should be placed with the grain vertical. Each block is prepared
with a groove on each side to receive a fillet which is fixed for the purpose on
each side of every joist. The blocks are also prepared with a groove on each side
to receive a tongue or projection which will engage with the corresponding groove
in the adjoining block. The said groove and tongue may be of any shape and
placed in any position, but they are preferably straight and horizontal, with the
object of rendering the floor completely air-tight from the ceiling below to the
top of floor above.
Referring to the accompanying drawings in which similar letters denote
corresponding parts throughout the several views,
Figure is a plan of a floor with the flooring boards removed constructed
according to our invention,
Figure 2 is an enlarged perspective view of a portion of the complete floor
showing more clearly the details. of construction and
Figure 3 is a further enlarged view of a single block, in accordance with our
invention, shown detached:
A are the joists, B the blocks, C the side grooves and D the end grooves in the
same; E are the fillets and F the tongues.
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 :-
A fireproof floor in which wood blocks with their grain vertical are filled' in
solid between the joists and formed with grooves or recesses in their sides and
ends to receive fillets or tongues substantially us and for the purposes specified.
