PROVISIONAL SPECIFICATION.
Improvements in Side Souttles or Port Lights for Ships.
We, MARK WILLIAM SWINBURNE, Engineer, CHARLES SWINBURNE,
Engineer and FRANCIS GILL, Brassfinisher, all of Wallsend Brass Works,
Wallsend-on-Tyne in the County of Northumberland, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in side scuttles or port lights for ships
and is designed to give light and ventilation by being constructed so as to allow
the glass frame to swing fore and aft or turn on pivots within a hinged frame,
the latter being fitted to the ordinary outer frame or back which is bolted to the
ship.
The hinged frame carrying the glass pivoted frame aforesaid can be opened and
closed in the usual manner being screwed down by the ordinary hinged bolt and
handle and when open it allows the port to be fully open.
We thus combine in a hinged sidelight frame a pivoted glass frame so arranged
or fitted that when the glass frame is held closed in the hinged frame the latter
resembles an ordinary hinged sidelight but by releasing the glass frame the latter
can be turned or swung on its pivots when the hinged frame is sufficiently far
opened to allow it to do so.
A simple screw is used to lock or unlock the pivoted glass frame in the hinged
frame.

COMPLETE SPECIFICATION.
Improvements in Side Scuttles or Port Lights for Ships.
We, MARK WILLIAM SWINBURNE Engineer, CHARLES SWINBURNE,
Engineer and FRANCIS GILL, Brassfinisher all of Wallsend Brass Works,
Wallsend-on-Tyne in the County of Northumberland, 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 side scuttles or port lights for ships
and we will proceed to fully explain it with reference to the accompanying
drawings in which Figure 1 shows a front elevation with all parts closed, Figure 2
being a sectional plan view on line x y, y z in Figure 1; Figure 3 is a similar view
to Figure 2 but showing the glass frame open as hereinafter described and in the
following description like marks of reference designate like parts.
Referring to the drawings, a is the outer frame which is fixed or bolted to the
ship. F is a circular frame resembling an ordinary side light frame hinged at H
to the frame a and having lugs L for being tightened up by the swing bolts B.
Within this frame F we pivot at P P the glass frame G and when the parts are
closed the frame G is held or locked in the frame F by the screw S.
The combined frames F and G can thus be swung open on the hinge H, the

page_text: frames F and G thus resembling an ordinary hinged side light, but supposing the
parts to be closed as shown in Figures 1 and 2 then by slacking the swing bolts B
the frame F can be opened so as to allow frame G to revolve on its pivots, the
screw S having first heen withdrawn to allow G to swing as described or as shown
for example in Figure 3. is a handle or knob for pulling open the glass
frame G.
Again supposing the parts to be closed as shown in Figures 1 and 2, a convenient
method is to slack back one of the swing bolts B; then the flanged bush b on the
handle of the other can be used to slightly open the frame F which enables
frame G (after being released by screw S) to be turned to any required angle;
then by again slightly tightening the swing bolt, the frame G can be locked at the
angle required against the rubber ring R.
A dead door can be hung at D to form a tight joint with the edge V, the edge V₁
forming a watertight joint with the rubber ring R.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
In side scuttles or port lights for ships the combination with a circular hinged
frame such as F arranged to be opened and closed of a pivoted glass frame G
arranged to be opened or closed, the parts being arranged with regard to each
other and to the fixed outer frame a and adapted for use substantially as herein
described and illustrated in the accompanying drawings.
