PROVISIONAL SPECIFICATION.
Improvements in Flooring.
We, MATTHEW DEAN GOODWIN and WILLIAM DORWARD both of Motherwell
Bridge Works, Motherwell, in the County of Lanark, Engineers, do hereby declare
the nature of the said invention to be as follows :-
"
This invention relates to flooring designed to replace that known as " section
and others composed of sheets or plates rolled or pressed to special forms for use in
floored bridges and for fire proof floors in buildings and the like. The improved
flooring is built up of narrow flat plates and angle or similar sections of iron or
steel bars which are always obtainable in the market, the plates being fitted in
lengths inclined at or approximately at right angles to each other and secured
together by rivetting or bolting them to angle bars extending longitudinally along
the lines of intersection of the inclined plates so that the flooring resembles a series of
alternate V-shaped ridges and furrows or troughs which may be subsequently filled
up with concrete or other material. The flooring so formed is or may be strengthened
and stiffened by transverse T or angle iron bars bent to V-form to fit the plates to
which they are rivetted at suitable distances apart, and transverse angle bars may be
fitted at intervals to connect the flooring to the carrying girders.

COMPLETE SPECIFICATION.
Improvements in Flooring.
We, MATTHEW DEAN GOODWIN and WILLIAM DORWARD both of Motherwell
Bridge Works, Motherwell in the County of Lanark, Engineers, 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 flooring designed to replace that composed of sheets or
plates rolled or pressed to special forms for use in floored bridges and for fire proof
floors in buildings and the like. The improved flooring is built up of narrow flat
plates and angle or similar sections of iron or steel bars which are always obtainable
in the market, the plates being fitted in lengths inclined at or approximately at right
angles to each other and secured together by rivetting or bolting them to angle bars
extending longitudinally along the lines of intersection of the inclined plates so that
the flooring resembles a series of alternate V-shaped ridges and furrows or troughs
which may be subsequently filled up with concrete or other material. The flooring so
formed is or may be strengthened and stiffened by transverse T or angle iron bars
bent to V-form to fit the plates to which they are rivetted at suitable distances apart,
and transverse angle bars may be fitted at intervals to connect the flooring to the
carrying girders.
In the accompanying drawings which illustrate the invention
Figure 1 is a cross sectional perspective view of the flooring which is composed of
flat plates A, secured together by angle bars B, rivetted thereto. The flooring may
be made to any depth and of such sections as will produce the requisite strength to
suit the various spans or loads for which it may be required.
Figure 2 shews the flooring with the ends of the troughs built into the wall of a
warehouse or other building.
Figure 3 indicates the manner in which the flooring may be supported on a wall

page_text: head, or on a beam, or other flat surface. In this case angle or other frames C, are
inserted to form end bearings.
In Figure 4 the troughing is shown extending over the top of girders D, to form
the decking and side footways of a railway or road bridge and in Figure 5, it is shown
applied to the bottom flange of main girders D, in lieu of cross girders etc.
In cases where it is necessary to curtail the depth from the underside of the girders
to the surface of the covering, the flooring may be supported on angle brackets E,
fixed to the web of the girders as indicated at Figure 6.
Figure 7 shows a section of the flooring strengthened and stiffened by suitably
shaped T- or L-bars F.
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 improved flooring composed substantially as described of flat plates and angle
or like bars rivetted or bolted together.
