Improvements in Corrugated Plates for the Floors of Bridges, }
Warehouses, and the like.
I, 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 budge
and warehouse floors and the like and for use in the construction of tank sides and
bottoms and for other purposes, such for stance as troughs made in one, two or
more corrugations, fire boxes of boilers and the like.
In order that my invention may be the more readily understood have caused
to be annexed to this Specification two sheets of drawings, the different figures
and letters of reference upon which will be deemed to form a part of this
Specification.

a bridge and illustrating two different applications of my invention.

Iron, steel or other corrugated metal floor plates have been made from sheets
pressed in one, two or more corrugations but with the same section 1unning
through from end to end of the same plate. These methods present difficulties in
making good attachments to the members to which the plates have to be secured.
In cari ying out my invention cause each end of the said plate to be flattened, as
shewn upon the left hand sides of Figures 1 and 2, and also upon Figure 5; or
flattened and flanged as shewn upon the right hand sides of Figures 1 and 2, and
also upon Figure 6.
By these means each plate can be attached, its whole width, to the member to
which it has to be vetted or other wise secured. I further effect an improvement
by providing recesses A in suitable positions in or near the side drains, thesu
recesses having holes or perforations B therein through which all drainage flows
and is carried therefrom by any suitable conductor or conductors. The plates
are pressed or formed, as will be seen upon referring to the drawings, with a
cambe from the middle thereof to the drain holes B and also from the ends to the
said drain holes, thus allowing all drainage to flow to the drain holes and preventing
any water or drainage from running to the girder to which the flooring may be
connected. It will be seen that the flange C on the end of the plate taken in
connection with the flattened out portion thereof forms a gutter D along each side
of the floor.
It is evident as already stated that my improved form of corrugated plates and
methods of connecting to the main supports may be used for a variety of purpose>
such as in the construction of tanks and the like, but
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 18:
1. The improvements in corrugated metal plates for the flooring of bridges,

without flanges and outlets for drainage and with falls towards the said outlets
substantially as described and illustrated.
2. The improvements in corrugated metal plates for the construction of tank
sides and bottoms, troughs, fire boxes of boilers and the like the said plates being
flattened at the ends and rivetted or otherwise secured in any well known manner
to the members or main supports and substantially as described and illustrated.
