PROVISIONAL SPECIFICATION.
Improvements in and connected with Water-tight Doors, Scuttles,
and the like for Ships.
1, HENRY MECHAN, of the Firm of Mechan and Sons, of Neptune Works,
60, Elliot Street, in the County of the City of Glasgow, North Britain, Engineer,
do hereby declare the nature of this invention to be as follows, that is to say:-
My said invention has for its object the constructing of water-tight doors,
scuttles, and the like and their frames for ships in an improved, simple, and
economical manner.
In carrying out my invention I form the door of a single steel or iron or other
metal plate, without riveting on edge flanges as is usually done, but with edge
flanges produced in the plate itself by means of an hydraulic press. I also by the
same means and at the same time form a shallow groove or recess in the plate just
within the edge flanges to receive the strip of rubber or compressible material by
means of which the water-tightness is obtained. The door plate may also, at the
same time have bucklings or corrugations formed in it.
I also form the door frame out of a single plate by means of an hydraulic press
in which press the door opening is cut out, and the frame has formed on its inner
edge the Hange the edge of which bears on the rubber or compressible strip of the
door, when the latter is closed.
The fastenings and other parts may be constructed and arranged as heretofore.

COMPLETE SPECIFICATION.
Improvements in and connected with Water-tight Doors, Scuttles,
and the like for Ships.
I, HENRY MECHAN, of the Firm of Mechan and Sons, of Neptune Works,
60, Elliot Street, in the County of the City of Glasgow, North Britain, 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, that is to say :-
My said invention has for its object the constructing of water tight doors,
scuttles, and the like, and their frames for ships in an improved simple and
economical manner.
In carrying out my invention I form the door of a single metal plate, having
produced in itself the edge flanges and a shallow groove or recess just within them
to receive the compressible material by means of which the water-tightness is
obtained.
I also form the door frame out of a single plate, in which the door opening is
cut and its edges are pressed to form the flange which bears on the compressible
material of the door.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings, to be
hereinafter referred to, and showing, a water-tight door as made according to my
invention.

page_text: Figure, 1, of the drawings is a front elevation, Figure, 2, a horizontal section, and
Figure, 3, a vertical section, of the door and frame.
Figure, 4, is a back elevation of the door.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
I form the door, A, of a single steel or iron or other metal plate, without
riveting on edge flanges as is usually done, but with edge flanges, B, produced in
the plate itself by means of an hydraulic press. I also by the same means and at
the same time form a shallow groove or recess, C, in the plate, A, just within the
edge flanges, B, to receive the strip of rubber or compressible material, D, by
means of which the water-tightness is obtained. The door plate, A, might also at
the same time have bucklings or corrugations (not shown) formed in it.
The door frame, F, is also formed out of a single plate by means of an hydraulic
press in which press the door opening is cut out and the frame has formed on its inner
edge the flange, G, the edge of which bears on the rubber or compressible strip, D,
of the door, A, when the latter is closed.
The fastenings and other parts may be constructed and arranged as heretofore.
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. Forming a water-tight door, or a scuttle or the like for ships, out of a single
metal plate having the edge flanges and a shallow groove or recess produced in
itself substantially as hereinbefore described.
2. In combination a water-tight door and its frame each made by means of
nydraulic apparatus out of a single metal plate and the door having a shallow
groove for compressible material and the frame having a flange to bear on that
material substantially as hereinbefore described.
