PROVISIONAL SPECIFICATION.
Improvements in Ships' Side Lights.
I, THOMAS UTLEY, Sefton House, Crosby Green, West Derby, Liverpool, in
the County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to ships' side lights, and has for its chief object to provide
for allowing the glass-holder to be detached from the fixed frame without
necessitating the removal of the hinge pin. The said invention is more especially
intended for application to side lights having a steel frame, and steel glass-holder,
but it is equally applicable to side lights made of brass. When applied to steel
side lights one feature of the invention is that it prevents corrosion between certain
of the parts as hereinafter described.
The hinge pin is fastened in the lug of the glass-holder and bears on one side
against a knuckle formed on or fixed to the stationary frame of the side light, and
on the other side against a brass piece which is removably secured to the knuckle,
preferably by screws. By removing the said screws the brass piece is liberated
and can then be withdrawn, whereupon the glass-holder can be removed without
disturbing the hinge pin. The brass piece before mentioned is so constructed that
its ends pass between the ends of the knuckle and the lug of the glass-holder so as
to form a brass bearing between said parts, and thereby prevent corrosion which
would take place at these parts if the same were made of steel and allowed to work
in contact with each other. These end bearing-pieces may be dispensed with when
the side lights are made of brass.

COMPLETE SPECIFICATION.
Improvements in Ships' Side Lights.
I, THOMAS UTLEY, of Sefton House, Crosby Green, West Derby, Liverpool,
in the County of Lancaster, Engineer, do hereby declare the nature of this inven-
tion, 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 ships' side lights, and has for its chief object to provide
for allowing the glass-holder to be detached from the fixed frame without
necessitating the removal of the hinge pin. The said invention is more especially
intended for application to side lights having a steel frame, and steel glass-holder,
but it is also applicable to side lights having brass frames. As applied to steel
side lights, one feature of the invention is that it obviates corrosion between
certain of the parts as hereinafter described.
In the accompanying drawings,

page_text: Figure 4 is a section of the hinge piece hereinafter described.
Figure 5 is a side elevation; and
Figure 6 is a section of a slightly modified form of hinge intended for a side
light the frame of which is made wholly of brass for example.
A is the fixed frame of the side light which is secured to the ship's side in the
usual manner; B is the glass-holder hinged to the frame A; C is the hinge pin.
The said pin C is fastened in the lugs B₁ of the glass-holder and bears on one side
against a knuckle D formed on or fixed to the stationary frame A, and on the other
side against a bearing or piece E preferably made of brass, which piece is
removable, but is secured in position to the knuckle by screws E¹ or equivalent
means. The said piece E is preferably constructed with end wings E' which pass
between the ends of the knuckle D and the sides of the lugs B₁ of the glass-
holder so as to form a bearing between said parts. This construction is specially
advantageous when the parts B¹ and D are made of steel (as is the case in
Figures 1 and 2) as it obviates corrosion between said parts which would be likely
to occur if the same worked in contact with each other. The end wings E may
be dispensed with if the whole of the frame and glass-holder are made of brass or
like metal. Such a construction is shown in Figures 5 and 6. This figure also
shows the same form of hinge applied to the metal cover F for closing the side-
light when required. By removing the screws E', the piece E is liberated and can
then be withdrawn, whereupon the glass-holder can be removed without disturbing
the binge pin which remains fixed in the lugs B'.
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. In a ship's side-light, the fixed frame furnished with the knuckle which forms
one side of the hinge in combination with the removable piece E secured to said
knuckle and forming the other side of the hinge, and the glass-holder B, or
cover F, having the hinge-pin permanently secured therein, for the purpose
specified.
2. In such a side-light the side wings E³, E of the removable piece E which
said wings pass between the knuckle and the lugs of the glass-holder, substantially
as described; and for the purpose specified.
Dated this 16th day of March 1894.
