PROVIDIUNAL DPECIFICATION.
Non-conducting Fireproof Substance and Composition, especially
applicable for Use in the Construction of Fireproof Buildings
or Parts of same.
We, WILLIAM HENRY JAMES, of No. 60, Eaton Terrace, Pimlico, in the
County of Middlesex, Builder's Assistant, CHARLES WALLIS, of 73, Brookdale
Road, Hoe Street, Walthamstow, in the County of Essex, Building Contractor,
and WALTER MACKINNON, of 12, Taviton Street, Gordon Square, in the County
of Middlesex, Clerk of Works, do hereby declare the nature of this invention
to be as follows:
This invention relates to a non-conducting fireproof substance and composition,
especially applicable for use in the construction of fireproof buildings or parts
of same, such for instance as the floors, walls, roofing, partitions, and for other
purposes. The object of our invention is to render buildings or other structures
or certain parts thereof absolutely fireproof at a small cost, and light but strong
and lasting. For this purpose we utilize a substance which is a waste product
from blast furnaces, namely the residue known as slag or clinker.
This slag or clinker is chiefly obtained from furnaces used in the manufacture
of iron and some other metals, but that obtained from glass and other like
furnaces we also employ sometimes, according to requirements.
When we refer to the fireproof substance we mean the plain slag or clinker
itself, and when we refer to the fireproof composition we mean the ground-up
slag mixed with Portland cement, lime, plaster, or other fireproof cement, or
mastic.
The fireproof substance may be employed, for instance, to fill-in between
the flooring boards and joists of a floor, in such manner as to embed the joists,
or between the plaster shell of walls and elsewhere as required.
The fireproof composition may be employed for instance as a material for
making fixing-bricks, or for mortar in place of sand, for artificial stone for all
purposes, for casing ironwork or wood in building construction.
The chief advantages to be derived from the employment of this substance
and composition for flooring &c. over other materials hitherto employed for
this purpose, are, its great lightness with strength, it is quicker drying, will wear
longer, is a better non-conductor, more economical by requiring less cement
and water, and with all is as cheap as any.

Non-conducting Fireproof Substance and Composition, especially
applicable for Use in the Construction of Fireproof Buildings
or Parts of same.
We, WILLIAM HENRY JAMES, of No. 60, Eaton Terrace, Pimlico, in the
County of Middlesex, Builder's Assistant, CHARLES WALLIS, of 73, Brookdale
Road, Hoe Street, Walthamstow, in the County of Essex, Building Contractor,
and WALTER MACKINNON, of 12, Taviton Street, Gordon Square, in the County
of Middlesex, Clerk of Works, 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:-
This invention relates to a non-conducting fireproof substance and composition,
especially applicable for use as a filling material in the construction of fireproof
buildings or parts of same, such for instance as the floors, walls, roofing, partitions,
and for other purposes. The object of our invention is to render buildings
or other structures, or certain parts thereof, absolutely fireproof at a small cost,
and light but strong and lasting. For this purpose we utilize a substance which
is a waste product from blast furnaces, namely the residue known as slag or
clinker.
This slag or clinker is chiefly obtained from, furnaces used in the manufacture
of iron and some other metals, but that obtained from glass and other like
furnaces we also employ sometimes, according to requirements.
When we refer to the fireproof substance we mean the plain slag or clinker
itself, and when we refer to the fireproof composition we mean the ground-up
slag mixed with Portland cement, lime, plaster, or other fireproof cement, or
mastic.
The fireproof substance may be employed, for instance, to fill in between
the flooring boards and joists of a floor, in such manner as to embed the joists,
or between the plaster shell of walls and elsewhere as required.
The fireproof composition may be employed, for instance, as material for
making fixing-bricks, or for mortar in place of sand, for artificial stone for all
purposes, for casing ironwork or wood in building construction.
The chief advantages to be derived from the employment of this substance and
composition as a fireproof filling for flooring &c., over other materials hitherto
employed for this purpose, are, its great lightness with strength; it is quicker
drying; will wear longer, is a better non-conductor; more economical by
requiring less cement and water, and, with all, is as cheap as any.
The following is a list of some of its most useful applications, but given only
by way of example, other uses will naturally suggest themselves according to
requirements:-
For fireproof fixing-bricks.
"
use in the construction of partition walls.
"
use as an ingredient in conerete.
"
a material in place of sand for mortar.
"
"
"
use as shingle.
artificial stone for all purposes.
casing ironwork in building and other constructional work.
The slag or clinker being, as obtained from the furnaces, in pieces of various

page_text: reduced to pieces of uniform size. It is gauged as required with water and
Portland or other suitable cement, lime plaster, clay or any other such fireproof
binding material. We prefer, and use chiefly, what is known as fozy slag or slag
breeze, but sometimes ordinary broken slag, and sometimes again these two
combined in proportions according to the nature and position of the work to be
executed.
Assuming for example that it is required to lay or construct a floor with this
fireproof material, we might proceed as follows:
When laying the floor the same system is or can be employed as in the con-
struction of the well-known coke-breeze flooring: centering boards are erected to
within about an inch of the bottom flange of the joists, when the latter are of
iron or other metal, the material, previously gauged as already described, is
then thrown on to the boarding to the desired thickness. The composition must
then remain untouched until quite dry and hard before the centering-boards are
removed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. The combination with a floor, wall, or other structure of the slag or clinker
from blast, glass, or other furnaces, as a fireproof filling or casing for the floor,
wall, or other structure, as described.
2. The fireproof composition consisting of a mixture of slag or clinker from
blast, glass, or other furnaces, with lime, plaster, mastic Portland or other fireproof
cement or binding material, all in a dry, loose state, as and for the purposes
described.
3. The fireproof composition consisting of a mixture of slag or clinker from
blast, glass, or other furnaces, with lime, plaster, mastic, Portland or other fire-
proof cement or binding material and water, as and for the purposes described.
4. The fireproof composition consisting of a mixture of slag or clinker from
blast, glass, or other furnaces, with lime, plaster, mastic, Portland or other fire-
proof cement or binding material, all in a granular or pulverised state and loose
and dry, as and for the purposes described.
5. The fireproof composition consisting of a mixture of slag or clinker from
blast, glass, or other furnaces, with lime, plaster, mastic, Portland or other fire-
proof cement or binding material and water, as and for the purposes described.
6. The fireproof composition consisting of a mixture of slag or clinker from
blast, glass, or other furnaces, with lime, plaster, mastic, Portland or other fire-
proof cement or binding material and water, in block, brick, slab or other massive
form either plain or ornamental, as and for the purposes described.
