PROVISIONAL SPECIFICATION.
Improvements in Fire-proof Floors, Roofs, Girders, Joists,
and the like.
I, JOHN HOLMES BLAKESLEY, of 39 Victoria Street, in the City of
Westminster, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in fire-proof floors, roofs, girders, joists
and the like.
The fire-proofing material is divided into arches resting on the joists in one piece
backed up by cement or other suitable material.
From these arches depend limbs which hold flat tiles to form a level ceiling on
the underside. One such flat tile under each joist, and other or others filling the
space under the arch. Or the flat tile under the joist may be obviated by enlarging
the depending limbs of the arch horizontally to nearly meet under joist, and the
other tiles may be made in one piece with the arch.
The fire-proof casing in all parts is made of fire-clay, terra cotta, or any other
suitable fire-proof material, and the spaces, are where require 1, filled or levelled
with concrete in the usual way, or can be covered with asphalt or any other
material as desired.
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials and parts may be varied in many ways within the scope of
my invention.
Dated this 2nd day of April 1894.

COMPLETE SPECIFICATION.
Improvements in Fire-proof Floors, Roofs, Girders, Joists,
and the like.
I, JOHN HOLMES BLAKESLEY, of 39 Victoria Street, in the City of
Westminster, Civil Engineer, 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 :—
My invention relates to improvements in fire-proof floors, roofs, girders, joists
and the like.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a vertical section of a single arched block having limbs resting on
jcists with tiles. The dotted lines indicate a separate floor tile which may be fixed
or separate.
Fig. 2, is a vertical section of an alternate design.
Fig. 3, is a vertical section of a single arched block with ends herein termed
"limbs" resting on joists, and projecting limbs at the base.
Fig. 4, is a vertical section of a single arched block having struts, stays or
pendants and limbs to support tiles for ceiling.

page_text: The fire-proofing material is divided into arches or single arched blocks a,
resting on the joists b in one piece backed up by cement or other suitable material.
These arches end in limbs e suitably adapted for the abutment of the arch an for
the attachment of other required limbs.
From these arches depend limbs e which hold flat tiles d to form a level ceiling
on the underside. One such flat tile d under each joist, and other or others filling
the space left vacant under the arch. Or the flat tile d under the joist b may
be obviated by enlarging the depending limbs c of the arch horizontally to nearly
meet under joist as in Fig. 3, and the other tiles may be made in one piece with
the arch a.
In Figs. 1, and 2, I construct single arched blocks a with struts, stays or
pendants and projecting limbs c on each side for resting on the joists b. Beneath
each projecting limb c is constructed a smaller limb g to support tiles d for
ceiling.
If preferable as in Fig. 4, I form a single arched block a with projecting
limbs e for resting on the joists b. The arched block a on the underside is provided
with pendants e, these said pendants are provided with limbs for supporting tiles d
for ceiling.
The fire-proof casing in all parts is made of fire-clay, terra cotta, or any other
suitable fire-proof material, and the spaces, spandriles are where required, filled or
levelled with concrete, asphalt or other material in the usual way or can be covered
with concrete, asphalt or any other material as desired. Or the top may be
levelled by a flat tile attached or not to the arch.
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials and parts may be varied in many ways within the scope of
my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In fire-proof floors, the combination of single arched blocks a struts, stays or
pendants and limbs c resting on joists b with limbs g to receive the ceiling
tiles d, substantially as herein described and according to Fig. 1, of the accompanying
drawing.
2. In fire-proof floors, the combination of single arched blocks a struts, stays or
pendants and sides with limbs c resting on joists b, and limbs g to receive the
ceiling tiles d, substantially as herein described and according to Fig. 2, of the
accompanying drawing.
3. In fire-proof floors, the combination of single arched blocks a struts, stays or
pendants with sides having upper and lower limbs e the upper limbs e resting
on joists b, substantially as herein described and according to Fig. 3, of the
accompanying drawing.
4. In fire-proof floors, the combination of single arched blocks a having limbs c
resting on joists and the pendants e with limbs to receive the ceiling tiles d,
substantially as herein described and according to Fig. 4, of the accompanying
drawing.
5. In fire-proof floors, a single arched block of clay, for the purpose specified.
6. In fire-proof floors, the combination of the single arch a with the struts, stays
or pendants and flat ceiling tile underneath, for the purpose specified.
7. In fire-proof floors, the combination of the single arch a with the flat tile to
form floor above and supports either attached to the arch or separate for the
purpose specified.
