PROVISIONAL SPECIFICATION.
Improvements in Corrugated Plates for the Floors of Bridges,
Warehouses, and the like.
1, SAM STRICKLAND of Rose Bank, Borrowash in the County of Derby,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention has for its object improvements in corrugated plates for bridge
and warehouse floors and the like and for use in the construction of tank sides and
bottoms and for other purposes such as troughs made in one, two or more
corrugations, fire boxes of boilers and the like.
Iron, steel and other corrugated metal floor plates have hitherto generally been
made from sheets pressed in one, two or more corrugations but with the same
section running from end to end of the same plate. These methods present
difficulties in making good connections to the main girders or supports, to which
the plates have to be secured, there is also a difficulty of getting rid of the water
from such flooring without leading the same to the main girders or supports, which
is a source of constant decay to the latter.
In carrying out my invention I cause each end of the corrugated plate to be
flattened, or flattened and flanged or boxed up in any suitable manner so as to
lead the water or drainage clear of the main girders or supports and so as to provide
a convenient means of fixing the ends of the said corrugated plates, their full
width, to the flange or web of the main girders or members or to any other con-
venient beds or supports. The plates may be cambered or made with falls to lead
to drainage holes, the latter being placed in any suitable positions in the flooring
and connected to any convenient gutters, downpipes or conduits.
It will be evident that my improved plates may be flattened or boxed up in a
vanety of ways for the different purposes for which they are required and they
may be pressed or formed with flanges of any size, angle, direction or description
for fixing to the different supports, or to form a gutter or gutters at the side or
sides for leading off the drainage from the floor.

COMPLETE SPECIFICATION.
Improvements in Corrugated Plates for the Floors of Bridges,
Warehouses, and the like.
1, SAM STRICKLAND of Rose Bank, Borrowash in the County of Derby,
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 has for its object improvements in corrugated plates for bridge
and warehouse floors and the like and for use in the construction of tank sides and

page_text: bottoms and for other purposes such as troughs made in one, two or more
corrugations, fire boxes of boilers and the like.
Iron, steel and other corrugated metal floor plates have hitherto generally been
made from sheets pressed in one, two or more corrugations but with the same
section running from end to end of the same plate. These methods present
difficulties in making good connections to the main girders or supports to which
the plates have to be secured, there is also a difficulty of getting rid of the water
from such flooring without leading the same to the main girders or supports, which
is a source of constant decay to the latter.
In carrying out my invention I cause either or both ends of the corrugated
plate to be flattened, or flattened and flanged or boxed up in any suitable manner
so as to lead the water or drainage clear of the main girders or supports and so as
to provide a convenient means of fixing the ends of the said corrugated plates,
their full width, to the flange or web of the main girders or members or to any
other convenient beds or supports. The plates may be cambered or made with
falls to lead to drainage holes, the latter being placed in any suitable positions
in the flooring and connected to any convenient gutters, downpipes or con luits.
My improved plates may be flattened or boxed up in a variety of ways for the
different purposes for which they are required and they may be pressed or formed
with flanges of any size, angle, direction or description for fixing to the different
supports, or to form a gutter or gutters at the side or sides for leading off the
drainage from the floor or the like.
In further describing my invention reference will be had to the accompanying
sheet of drawings which will be deemed to form a part of this Specification.
Figures 1 and 2 are perspective views shewing the application of my invention
to corrugated metal floor plates suitable also for the bottoms of tanks and the like;
on Figure 1 both ends A. B. of the corrugated plate are shewn boxed up and
in Figure 2 the near end C is shewn boxed up and finished with a flange while
at the end D it will be seen the ends of the corrugations are boxed up and a
gutter E is also formed at the side for conveying the water or drainage away,
drainage holes F being provided in any suitable position or positions. It will
be readily understood from Figures 1 and 2 that these plates may be rivetted,
bolted or otherwise fixed to the main girders or supports in a variety of ways
and that different forms of boxing up may be employed.
Figure 3 is a sectional view shewing the application of my invention in forming
a flashing piece G at the junction of the corrugated plate H with the vertical
side I of a louvre ventilator.
Figure 4 is a similar view to the latter shewing the application of my invention
as a flashing piece J under the lower edge of a piece of glass roofing or
skylight K.
Figure 5 is a sectional view shewing the application of my invention to the
formation of a ridge when the sloping sides of the roof are formed of corrugated
plates L. M. In this instance a plate is first pressed as shewn upon Figures 6
and 7 which are a plan and section respectively, the section being taken upon
line a. a. of Figure 6, the flat central portion N is then bent or formed into the
ridge roll O of Figure 5 and the whole firmly rivetted or otherwise secured to the
lower corrugated roofing plates L. M, or in other suitable manner.
Although I have only illustrated a few applications of my invention it will be
evident that it may be applied to a variety of purposes in which corrugated plates
are used.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The improvements in corrugated metal plates used in the construction of floors,
roots, tanks and for other purposes, consisting of boxing up or flattening the ends
or other portions thereof in various manners and for various purposes; drainage

page_text: holes and gutters, flanges or other means of securing the same to the main girders
supports or constructional work being provided, substantially as described and
illustrated.
