ALEXANDER WEIR Brassfounder and Machinist 20 Fleet Street Belfast do hereby
declare the nature of this invention to be as follows:-
This invention has for its object to improve the construction and action of Hinged
Ship Side Lights, to render them capable of being opened and shut speedily and
securely to prevent unautherised persons from opening them when shut, and to
diminish loss arising from breakage of the glasses.
To secure these advantages the inventor gives the following description of the
various parts, accompanied with drawings, marked with letters on sections No. 1 and 2
berewith sent.
The frame that holds the glass is a separate casting A and distinct from the
hinged binding-down frame B. both of which are pivoted or jointed together in the
middle and held in their position by two set pins C. This arrangement allows
the frame that holds the glass to swivel on its pivots D and accomodate itself to
lie flat on any untrueness that inay be on the India Rubber seat or ring E thereby
ensuring a water tight joint without unequal strain on its parts, there is a binding
down nut having one or more holes in its flange F for fixing a padlock to or other
locking arrangement in conjunction with binding down frame or body of side light.
The India-Rubber seat or ring E is securely kept in its position by being placed
into a grove having an overlapping rim or flange on top on each side. The body
of side light for fixing to ship is made to accomodate a portable metal disc or
dead light H which on being used is kept in position by the binding nut bearing
on top of frame as shewn in Section 1.

Improvements in Hinged Ship Side-lights.
I, ALEXANDER WEIR, of 20 Fleet Street, Belfast, Brassfounder and Machinist,
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, reference being also had to the drawings accompanying my Provisional
Specification :-
The improved device according to my Invention consists of a frame A within
which is mounted, in the ordinary manner, the glass of the side light. Said frame A
is secured at the -top-and bottom of the "binding-down-frame" B by the pivoting
pins C, to allow of the frame A revolving freely therein upon the pivoting points D.
Around the flange with which the frame A is provided is a groove or channel into
which is adapted an india rubber or other packing ring E, held firmly in its bed
or seating by narrow flanges overlapping said groove or channel. The ordinary
binding down bolt and nut for securing the side light is provided with a flange F
having perforations formed therein to allow of the insertion of a pad-lock, bolt or
the like for preventing the unscrewing of said binding down nut during the
prevelance of rough weather, or at other times when it is found advisable to keep the
lights closed.
As a further protection during stormy weather I provide a flanged dead light H so
formed as to fit into the ships side, and which is pressed there against by the side
light above described; a packing ring of india rubber or equivalent inserted in a
groove formed for the purpose, serving to ensure a tight joint.
It will be obvious therefore that inasmuch as the glass frame A has a free swinging
motion, the pressure thereof brought to bear upon the rubber ring is uniform at
all points, irrespective of the amount of pressure exerted upon the frame B by the
binding down nut aforesaid.
1 may, in cases of the adaptation of large side lights, employ two or more binding
down bolts and nuts disposed at equal distances apart relatively to the hinge of the
frame B.
As an addition to the internal dead light above described, and with a view to
ensuring greater security against the ingress of water through the side lights, I
provide an interior shutter which may be hinged to snugs formed for the purpose
upon the inner surface of the frame of the side light aforesaid, and secured by a
binding-down nut, or (in the case of large side-lights) by binding-down nuts in
the manner above described Said interior shutter may be provided with a pro-
jecting ring, which pressing in a packing of india rubber inserted in a groove in
the frame B or in the ship's side, ensures a tight joint-Instead of the hinged shutter
above described, I may use a hinged frame to which a shutter is pivoted or otherwise
adapted, to allow of the pressure against the rubber seating being uniform at all
points.

page_text: 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 :-
First In ships side lights the method which I adopt of equalising the pressure
thereof when closed, substantially as herein described.
Second-In ships side lights the mode of and means employed for locking same
when closed, substantially as herein set forth.
Third The Improvements in hinged ship side-lights substantially as herein set
forth.
