PROVISIONAL SPECIFICATION.
Improvements in the Making of Ships' Side Lights.
I, HENRY MECHAN, of the Firm of Mechan & Sons, of Neptune Works, 60,
Elliot Street, in the County 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 making of ships' side lights in an improved
manner.
In carrying out my invention I form the frame for a side light by cutting an
aunular plate of sheet steel or other metal and first stamping or shaping it to form
a cylindrical flange to fit in the opening in the ship's plating. By subsequent
stamping or pressing operations I form a projecting rim or bead round the corner
of the frame, to be afterwards finished by turning to serve as the narrow bearing
to be in contact with the rubber packing on the dead-light or on the glazed frame.
The operation may be reversed; namely, by forming a groove or recess in the
stamped frame to hold rubber the bearing projection being formed on the brass
glazed frame. At subsequent operations the frame ring has welded upon it the
several lugs for the hinges and other fastening parts. The dead-light is formed by
suitably stamping or shaping a plate of iron or steel, a hinge piece being afterwards
welded upon it, whilst it is shaped with a projection opposite to the hinge part, such
rojection being formed into a pair of jaws to engage with the swivelling screw
fastening which secures the dead-light when closed.

Improvements in the Making of Ships' Side Lights.
I, HENRY MECHAN, of the Firm of Mechan and Sons, of Neptune Works, 60,
Elliot Street, in the County 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 making of ships' side lights in an improved
manner.
In carrying out my invention I form the frame for a side light by cutting an
annular plate of sheet steel or other metal, and first stamping or shaping it to form
a cylindrical flange to fit in the opening in the ship's plating. By subsequent
stamping or pressing operations I form a projecting rim or bead round the corner
of the frame, to be afterwards finished by turning to serve as the narrow bearing
to be in contact with the rubber packing on the deadlight or on the glazed frame.
The operation may be reversed; namely, by forming a groove or recess in the
stamped frame to hold rubber, the bearing projection being formed on the brass
glazed frame. At subsequent operations the frame ring has welded or otherwise

light is formed by suitably stamping or shaping a plate of iron or steel, a hinge
piece being afterwards welded or fixed upon it, whilst it is shaped with or has
fixed to it a projection opposite to the hinged part, such projection being formed
into a pair of jaws to engage with the swivelling screw fastening which secures the
deadlight when closed.
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 ship's side light as made with my
improvements.
Figure, 1, of the drawings is a side elevation, and Figure, 2, a vertical section as
at right angles to Figure, 1. In these drawings the same reference letters are used
to mark the same or like parts wherever they are repeated.
I form the frame for a side light by cutting an annular plate, A, of sheet steel or
other metal and first stamping or shaping it to form a cylindrical flange, B, to fit
in the opening in the ship's plating. By subsequent stamping or pressing opera-
tions I form a projecting rim or bead, C, round the corner of the frame, A, to be
afterwards finished by turning to serve as the narrow bearing to be in contact with
the rubber packing, D, on the deadlight, E, or on the glazed frame, G. At
subsequent operations the frame ring, A, has fixed to it the several lugs, H, J, K,
L, and M, for the hinges, P, and Q, and other screw fastening parts, R, S, and T.
The dead light is formed by suitably stamping or shaping a plate, E, of iron or
steel, the hinge piece, P, and a projecting piece, V, being afterwards fixed upon it,
such projecting piece being opposite to the hinge piece and formed into a pair of
jaws to engage with the swivelling screw fastening, R, which secures the dead-light
when closed.
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 :-
Constructing the frames and dead-lights of ships' side lights substantially in
the improved manner herein before described and shown in the accompanying
drawings.
