PROVISIONAL SPECIFICATION.
Improvements in or relating to Corrugated or Channelled Flooring
for Bridges and other Structures.
I, JOSEPH SHEWELL of Albert Hill, Darlington in the County of Durham,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of corrugated flooring
for bridges and other structures. Hitherto such floorings have been usually made
with plain open ends so that the surface water readily gets past the ends of the
flooring unless stopped by cement, asphalt or the like." A leakage of water is in
fact often liable to take place.
Now my invention is designed to avoid any possible leakage, and enable the
flooring to be firmly united to the main girders of the structure.
In carrying my invention into effect, I flange the ends of the corrugations so as
to make the flooring a kind of trough or channel with closed ends. By means of
these flanges, the surface water cannot flow past the ends and the flooring also can
be securely united to the main girders by these flanges and very readily made
water-tight.

Improvements in or relating to Corrugated or Channelled Flooring

I, JOSEPH SHEWELL,. of Albert Hill, Darlington, in the County of Durham,
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 improvements in the construction of corrugated flooring
for bridges and other structures. Hitherto, such floorings have been usually made
with plain open ends, so that the surface water readily gets past the ends of the
flooring unless stopped by cement, asphalt or the like. A leakage of water is in
fact often liable to take place.
Now my invention is designed to avoid any possible leakage, and enable the
flooring to be firmly united to the main girders of the structure.
In carrying my invention into effect, I flange the ends of the corrugations so as to
make the flooring a kind of trough or channel with closed ends. By means of
these flanges, the surface water cannot flow past the ends, and the flooring also can
be securely united to the main girders by these flanges and very readily made
water-tight. Moreover, they stiffen the web of the main girder.
In order that my invention may be more thoroughly understood, I append the
accompanying drawings of part of a bridge; in which-
Figure 1 is a transverse section of part of the flooring and part of the girder of
a bridge:
Figure 2, section at right angles thereto :

:.
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 is :-
1. The improvement in or relating to corrugated or channelled flooring for
bridges and other structures, which consists in forming the corrugated flooring
pieces with terminal flanges substantially as and for the purposes described.
2. The arrangement of corrugated or trough flooring securely united to the main
girders substantially as set forth.
