HENTHORN STOTT, Junior, of the firm of Stott & Sons 60 Haworths Buildings,
Cross Street, Manchester, and 12 Clegg Street, Oldham in the County of Lancaster,
Architects, Consulting Engineers, Surveyors and Valuers, do hereby declare the
nature of the said invention for "IMPROVEMENTS IN FIREPROOF FLOORING FOR
COTTON AND OTHER MILLS AND BUILDINGS," to be as follows:-
The object of our invention is to construct an economical fireproof flooring for
Cotton, Woollen or other Mills or Buildings in such manner as to be able to dispose
the columns, which pass through each floor, so that when for cotton mills, there
will be no columns in the spaco occupied by each pair of mules, and yet so that
the columns when so arranged for the mules, will admit of the placing either single
or double carding Engines in the carding room below the spinning room with their
lengths in the same direction as the lengthway of the mules, without loss of space
and without the beams for carrying the floor unduly obstructing the light or
interfering with the arrangement of the driving belting as would be the case if
deep girders were used.
By the improved construction and arrangement above referred to, the number of
columns is reduced, which is a great convenience in cotton mills.
There are no columns in the space occupied by each pair of mules, thus there is
no risk of damage by skips or other articles being accidentally left in a position to
be crushed between the carriage of the mule when it draws out, and a column, and
besides these advantages there is also a saving of floor space.
Our invention consists in the combination arrangement and construction of the
parts as follows.
We arrange the columns of cast or wrought iron or other suitable material on
suitable foundations in parallel lines at suitable distances apart, that is, when for
cotton mills, so as to admit, when desired, of a row of double carding engines
being placed between each line of columns in one direction, without loss of space,
and in the other direction (at right angles to the first named) at such distances
apart as to admit of a pair of mules being placed between each line of columns
without loss of space.

page_text: We connect each line of columns in one direction by two parallel lines of girders
or beams of cast, wrought or rolled iron or steel or other suitable material-One
line of the said parallel girders or beams is placed on one side of the columns
and the other line of the said girders or beams is placed on the other side of the
columns; such girders or beams being affixed to and supported by brackets or
cantilevers, cast on or otherwise secured at or near to the top of the columns, one
on each side thereof.
The space between the two longitudinal parallel lines of girders or beams is or
may be filled in by concrete or other cement or material.
Between the longitudinal parallel lines of girders above referred to and at right
angles thereto we place and secure other girders or beams at such distances apart
as will be suitable for supporting arches of brick slabs or arches of concrete or
other fire proof material, and the surface above the arches is made of wood, flags,
tiles or other suitable material to form the floor of the room.

We ABRAHAM HENTHORN STOTT, JESSE AINSWORTH STOTT and ABRAHAM
HENTHORN STOTT Junior, of the firm of Stott & Sons 60 Haworths Buildings,
Cross Street, Manchester and 12 Clegg Street Oldham in the County of Lancaster,
Architects Consulting Engineers, Surveyors and Valuers 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 our invention is to construct an economical fireproof flooring for
Cotton, Woollen or other Mills, Wharehouses and other Buildings, in such manner
as to be able to dispose the columns, which pass or may pass through each floor, so
that when for Cotton Mills, there will be no columns in the space occupied by each
pair of mules and yet so that the columns when so arranged for the mules, will
admit of the placing either single or double cording Engines in the carding room
below the spinning room with their lengths in the same direction as the length way
of the mules without loss of space and without the beams for carrying the floor
unduly obstructing the light or interfering with the arrangement of the driving
belting as would be the case if deep girders were used.
By the improved construction and arrangement above referred to, the number of
columns is reduced, which is a great convenience in Cotton Mills.
There are no columns in the space occupied by each pair of mules thus there is
no risk of damage by skips or other articles being accidentally left in a position to
be crushed between the carriage of the mule (when it draws out) and a column,
and besides these advantages there is also a saving of floor space.
Our invention consists in the combination arrangement and construction of the
parts as follows.
We arrange the columns of cast or wrought iron, steel or other suitable material
on suitable foundations in parallel lines at suitable distances apart, that is, when
for Cotton Mills, so as to admit, when desired, of a row of carding engines being
placed between each line of columns in one direction without loss of space, and in
the other direction (at right angles to the first named) at such distances apart as
to admit of a pair of mules being placed between each line of columns without loss
of space.
We connect each line of columns in one direction by two parallel lines of girders
or beams of cast, wrought or rolled iron or steel or other suitable material-One
line of the said parallel girders or beams is placed on one side of the columns and
the other line of the said girders or beams is placed on the other side of the
columns such girders or beams being affixed to and supported by brackets or
cantilevers applied cast on or otherwise secured at or near to the top of the
columns, one on each side thereof or formed in one piece.
The space between the two longitudinal parallel lines of girders or beams is or
may be filled in by brick arching, slabs or arches of concrete or other fire resisting
material,

page_text: Between the longitudinal parallel lines of girders above referred to and at right
angles thereto we place and secure other girders or beams of cast or wrought iron,.
steel, or other suitable material at such distances apart as will be suitable for
supporting brick arching slabs, or arches of concrete, or other fire resisting material
and the surface above the fire resisting material is made of wood, flags, tiles or
other suitable material to form the floor of the room.
Fig. 1 is a plan view showing on bay of flooring according to our invention.
Fig. 2 is a sectional elevation on a line A-B fig. 1-and fig. 3 is a sectional
elevation on the line C-D fig. 1.
a are columns of one row of pillars, and a¹ columns of another row of pillars.
The space between the two lines of pillars a and a¹ we term a bay,
Upon the upper part of each column a or a' two brackets bare cast or formed
or are applied, secured thereto by bolts or in any convenient manner.
The columns a or a¹ are formed of cast or wrought iron steel or other suitable
material and the brackets are or may be by preference cast or formed with the
column or may be formed of cast or wrought iron or steel and applied or secured
thereto by bolts or otherwise.
To the brackets b we secure by bolts or otherwise wrought iron by preference or
steel or cast iron girder beams c of I or other suitable section so that these beams
extend from the brackets b on one coloumn a or a¹ to those of the next column, one
beam c on each side of the columns a or a¹ and we tie or otherwise secure the two
girder beams c to each other by ties d secured by screw bolts or otherwise at
suitable intervals.
The space between each pair of girder beams c we fill with brick arching slabs
or arches of concrete or other suitable fire resisting material.
Between the girder beams c supported by the pillars a or a¹ we place cross
girders e of wrought or cast iron or steel, by preference of I section and at suitable
intervals, to support arches of brick, or slabs or arches of concrete or other suitable
fire resisting material.
The cross girders c are or may be connected by the rods fat suitable intervals,
to resist the lateral thrust of the arches and strengthen the floor.
The upper surface of the brick work (when used) between the cross girders e is
filled up level by concrete or other suitable material and is or may then be covered
by flags of stone or tiles, or ribs of wood which are or may be bedded upon the
concrete or: cement to which the wood flooring boards g are secured.
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
The combination and arrangement of columns, brackets, beans and brick or
concrete or other fire proof or fire resisting materials forming a fire proof flooring
for cotton and other mills, warehouses or other buildings, substantially as and for
the purpose hereinbefore described and illustrated by the drawings,
