page_text: We, FRANCIS GILL and THOMAS GILL of No 7 Tweed Street Sunderland in the
County of Durham Brass Founders and Finishers do hereby declare the nature of
this invention to be as follows:-
The objects of our invention are to simplify and improve the construction of
side lights by dispensing with hinged joints and to secure a larger clear glass area.
Instead of the frame containing the glass working on a hinged joint on the fixed
frame on side of ship it is carried by lugs upon screwed studs (preferably two) in
the fixed frame, the inner rim. of which is fitted with an india rubber or other
elastic ring, against which ring the glass frame is screwed by hand nuts, working
on the screwed studs, with an equal pressure all round perfectly tight without the
common danger of breaking the glass.
When required to be open for ventilation both nuts are screwed back and the
glass frame moved inward against them leaving the required opening all round.
When required to be entirely open the glass frame is either removed or it may
be swung round on one of the studs clear of the opening. The dead shutter is a
flat disc and when required is slipped over the studs between the glass and main
frame and the nuts screw it against the elastic ring with equal pressure all round,
the glass frame remaining on inside. When not in use the dead shutter is hung
up attached by a chain and the full opening in the main frame is available for light
and air.

We FRANCIS GILL and THOMAS GILL of No 7 Tweed Street Sunderland in the
County of Durham Brass Founders and Finishers 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 :-
The objects of our invention are to simplify and improve the construction of side
lights by dispensing with rigid hinged joints and to secure a larger clear glass area.
Instead of the frame containing the glass working on a rigid hinged joint on the
fixed frame on side of ship it is carried by lugs upon screwed studs (preferably
two) in the fixed frame, the inuer rim of which is fitted with an india rubber or
other elastic ring, against which ring the glass frame is screwed by hand nuts,
working on the screwed studs, with an equal pressure all round perfectly tight
without the common danger of breaking the glass-When required to be open for
ventilation both nuts are screwed back and the glass frame moved inward against
them leaving the required opening all round-When required to be entirely open
the glass frame is either moved or it may be swung round on one of the studs clear
of the opening..
"
The dead-shutter" is a flat disc and when required is slipped over the studs
between the glass and fixed frame and the nuts screw it against the elastic ring
with equal pressure all round, the glass frame remaining on inside-When not in
use the "
dead shutter" is hung up attached by a chain and the full opening in the
fixed frame is available for light and air, or it may be swung round on one of the
studs in the same way as the glass frame.
"
In an alternative method, which is especially adapted for the larger class of side
lights, to enable the "dead-shutter" and glass frame to swing round on one of the
studs and keep clear of the frames or reverse frames of the ship, we fit.the "dead-
shutter or the glass frame, or both with a hinged joint formed in one of the lugs,
so that when the nuts are screwed back and the opposite lug is clear of the bolt
the shutter or glass frame, or both, turns inward upon the hinge joint to the
required extent and can then be turned down as before clear of the ships frames.
This hinged joint however bas no operation when the shutter or glass frame is
being screwed up by the hand nuts against the elastic ring in the fixed frame.
DESCRIPTION OF DRAWINGS..
Sheet 1 drawn to scale of one half actual size Figure 1 is a face view of the dead
shutter D. S. Figure 2 a side view with "dead-shutter" being screwed home
against the India rubber ring R (in the fixed frame F) on the bolts B B-fixed in
fixed frame by the hand nuts H. N Figure 3 is a face view looking outward
of the side light with dead shutter inserted and glass frame G. F in position and
Figure 4 a section through line X X on Figure 3, F being the fixed frame rivetted
to side plate of ship D. S the dead shutter R the elastic ring and G. F the glass
frame screwed against the "dead-shutter" by the hand nuts Figure 5 is a face
view of the fixed frame only looking outward, shewing the sockets for screwed
bolts B B and the groove fitted with India rubber ring R. and Figure is a
vertical section on line X X of .figure 5 in which the "dead-shutter" is removed
entirely and the glass frame is in position but closed by the hand nuts H N against
the elastic ring R-When required to be partially open for ventilation the glass
frame is drawn inward upon the bolts by screwing back the hand nuts, or, if
required to be entirely opened, one of its open jaws may be brought clear over the

page_text: end of its bolt when it will swing downward on the other bolt clear of the
opening-The dead shutter may also instead of being entirely removed be allowed
to swing clear of the glass on one of the bolts.
Sheet 2-drawn to scale of one fourth actual size illustrates the mode of fitting
larger sizes of side lights used in passenger steamers where the distance between
the frames does not allow room to swing the glass frame or dead shutter as just
described upon one of the stud bolts clear of the reverse frames-In fitting such
side lights we propose to form on the dead shutter, or on the glass frame, or both,
a hinge on one side between the shutter or glass frame and the stud bolt but this
hinge is perfectly free and does not in any way interfere with the screwing up of
the shutter or glass frame against the main frame, its only purpose being to enable
one or both, when clear of the opposite stud bolt, to open inward on the hinge and
when necessary swing downward on the stud bolt clear of the projecting flange of
the frame or reverse frame.
Figure 1 is a face view looking outward of a side light fitted, with the glass
frame only hinged both dead shutter DS and glass frame G F in position
Figure 2 is an elevation in plan, of same. Figure 3 is a section shewing dead
shutter removed and glass frame G F closed upon fixed frame F and Figure 4 is a
section shewing both dead shutter DS and glass frame G F in position and
closed-The bracket B K-shown on Figure 1. 2 and 5 is cast on fixed frame as a
support under the hinge joint while being screwed closo against the elastic ring or
until required to be swung round on the bolt clear of opening.
In Figures 5 and 6 a form of side light is shewn in which four bolts B B B¹ B¹
are employed all projecting inward from the fixed frame F.-Two of these bolts B B
apply to the glass frame G F and two B¹ B' to the dead shutter D S and in both
figures, the hinged joint is shewn as applied to the glass frame and also to the
shutter. In figure 5 the glass frame is shewn as in position with the dead shutter
full open on its hinge and in figure 6 the dead shutter is closed.-In all forms of
our invention the mode of screwing up against the elastic ring ensures a perfect
joint and any twisting or distortion of the side of ship in way of the side lights
does not affect this as in the case of side lights acting by rigid hinged joints in
which the glass is very frequently broken in screwing close the glass frame.
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,-

First. The improvements in ships side lights consisting in fitting the dead
shutter" and the glass frame, or either of them, upon stud bolts in main frame
upon which bolts they are closed by hand nuts with equal pressure all round
instead of closing upon a rigid hinge joint formed with the main frame; con-
structed and operating substantially as described and illustrated by Figures 1. 2 3.
4. 5 and 6 sheet 1 of the accompanying drawings.
Second. In ships side lights so constructed and operating the application to the
dead shutter and glass frame or either of them of a hinge joint intervening between
the shutter or glass frame and one of the stud bolts, with the objects herein before
stated, substantially as described and illustrated by Figures 1. 2. 3. 4, 5 and 6 of
Sheet 2 of the accompanying drawings.
