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
invention to be as follows:-
My invention relates to ships' side lights and provides an improved pivoted
square or rectangular side light adapted to be easily opened for ventilating
purposes.
The fixed casing of the side light is made to project inboard a considerable
distance and is furnished with an internally projecting flange to receive the usual
packing ring for making a water-tight joint between the casing and the glass-
holder. The latter is furnished with a projecting rim to bed against the aforesaid
packing ring.
The glass-holder is provided with pivots at the top and bottom which pivots.
The said grooves extend in
can slide in grooves provided in the fixed casing.
a direction perpendicular to the ships' side, so that when the retaining screws of
the glass-holder are unfastened the latter can be moved bodily outboard into a
position wherein it can be turned about its pivots.
In order that the glass-holder may not project too far I provide for allowing
it to be drawn inboard when open as follows, that is to say, I provide a hinged
piece in the top and in the bottom flange of the casing opposite the pivots of
the glass-holder. These hinged pieces can be turned down or up when the side
light is open and the glass-holder can then be drawn inboard through the slots
in the casing thus provided.

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
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to ships' side lights.
According to my invention I provide the glass holder with pivot pins about
which it can be turned when desired into a position approximately at right angles
to the ships' side. The said pivot pins are received in grooves or channels in
the fixed casing of the side light and can slide therein to allow of the turning
of the glass holder. The fixed frame is formed with an internal flange at its
inner end to receive the packing ring against which the glass-holder bears when
closed. In the said flange when applied to a rectangular side light, are gaps
closed by hinged closing pieces as and for a purpose hereinafter fully explained.

In the accompanying drawings,
Figure 1 is an elevation from inside the vessel of a rectangular side light
constructed according to my invention.
Figure 2 is a horizontal section on the line x, x Figure 1.
Figure 3 is a horizontal section showing an intermediate position of the glass
holder when opening.
Figure 4 is a vertical section on the line y, y Figure 1 showing a channel
hereinafter described.
Figure 5 is an elevation of a circular side light constructed according to my
invention.
A is the fixed casing of the side light; B is the movable glass-holder; C is the
glass.
The fixed casing A is made to project inboard a suitable distance and is
furnished with an internally projecting flange A¹ to receive the usual packing or
jointing ring A' for making a water-tight joint between the casing and the glass-
holder. The latter is furnished with a projecting rim B¹ to bear against the
aforesaid packing ring when the side light is closed.
The glass-holder is provided at top and bottom with pivot pins B', B' which are
received and can slide in grooves or channels A', A' provided in the fixed casing A.
The said grooves or channels extend in a direction at right angles to the ships' side,
so that when the retaining screws D, DD, D which are hinged to the glass-holder
are unfastened and disengaged from the jaws of the fixed casing the said glass-
holder can be moved bodily outboard to the position shown in Figure 3, that is to
say, until the pivot pins arrive at the ends of the channels. The side-light can
then be turned about its pivot pins into a position at right angles to the ships' side.
An intermediate position of the glass-holder while turning is shown by dotted lines
in the said figure.
The retaining bolts or screws are as above indicated hinged to the glass-holder
and can engage with jaws on the fixed frame. When the nuts of the retaining
bolts are screwed
up
the rim B of the glass-holder is pressed very tightly against
the packing ring A* and a perfectly water tight joint is thereby ensured.
strikes the glass it serves merely to increase the pressure of the holder against the
flange and so makes the joint more tight.
If a sea
In order that the glass-holder may not when open project outboard too far
I provide for allowing it to be drawn inboard, as follows, that is to say, I provide
a gap A' in the top and also in the bottom of the flange A' of the casing in line
with the pivot pins of the glass-holder, and I close said gaps by pieces A', A*
which are hinged to the casing. A', A' are the hinge pins of the said pieces. The
jaws As with which the top and bottom screw-retaining bolts D engage are formed
on the said pieces A* so that when the side light is closed and screwed home tight
by its bolts D the pieces A are kept tightly pressed against the part A of the
fixed casing. When the bolts D are unscrewed to open the side light, these
pieces AA can be turned back and the glass-holder can then be drawn inboard
through the gaps A' in the flange A'.
In some instances the fixed frame of the rectangular light is made so deep (the
grooves or channels being correspondingly lengthened) that the glass-holder will
turn without hindrance and without projecting outboard too far, and in such a case
it becomes unnecessary to provide the gaps and closing pieces in the flange.
My improved construction of side-light may obviously be applied to those lights
that have ventilator in the fixed frame.
The side light shown in Figure 5 is circular, and is pivoted at top and bottom in
channels in the fixed frame in the same manner as the rectangular light above
described. It is shown with two retaining bolts D, D, but it may have four such
bolts if desired. With a circular light it is not necessary to provide gaps in the

page_text: flange of the fixed frame to allow the glass-holder to be drawn inboard when
turned at right angles to the ships' side as is the case with the rectangular light.
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. A ships' side light comprising a fixed frame having an internal flange to
receive a packing or jointing ring and a glass-holder furnished with pivot pins that
are received, and can slide to and fro, in channels in the fixed frame, gaps being
provided in the said internal flange opposite the said channels, substantially as, and
for the purpose, specified.
2. The hinged pieces for closing the gaps in the fixed frame, said pieces having
ears to engage the screw retaining-bolts of the glass-holder, substantially as
described, and for the purpose specified.
3. In a ships' side light, a glass-holder having pivot pins about which the said
holder can turn, and screw retaining bolts hinged to the holder, and with or without.
the projecting rim to bear against the packing ring of the fixed frame, substantially
as, and for the purpose, described.
4. A ships' side light constructed substantially as described with reference to
either of the forms or modifications illustrated in the accompanying drawings for
the purpose specified.
