Improvements in Ships' Side Lights.
I, ALEXANDER ROBERTSON of Danson Terrace Carron in the County of Stirling,
Engineer, do hereby declare the nature of this Invention to be as follows:-
This Invention which relates to ship's side lights has for its object to provide
improved hinge and binding screw arrangements whereby, in closing the glass
holder and inside or "dead" shutter, the pressure or strain is uniformly distributed
all round the watertight bearing the said improved hinge being also adjustable to
suit any slight variation in the thickness of the rubber or other elastic packing of
the watertight bearing so as to obviate danger of the frames becoming hinge bound
and of fracturing the glass in closing or screwing up the light.
On the shipside frame two sets of jaws or lugs are cast one set being provided to
carry the glass holder or frame and the other set to carry the inside or "dead". shutter.
Through each set of these jaws or lugs there passes a pin or stud on which is centred
a connecting piece constituting a swivil joint and hinge and through the upper end of
each of these connecting pieces there passes another pin or stud at right angles to the pin
or stud attaching the connecting pieces to the jaws or lugs. The second mentioned pins
or studs pass through hinge screws or bolts and also through slotted holes made one in
the glass holder or frame and. the other in the inside or "dead" shutter, and these
screws or bolts are furnished with nuts these, besides being threaded on to the bolts,
being tapped into the glass frame and "dead" light or shutter and by turning which
the pressure on the india-rubber, or other elastic packing, is regulated: the said
nuts also making provision for wear or inequality in the thickness of the packing.
Under a modification instead of using the connecting pieces and pins by which
these are attached to the shipside frame the hinge screws or bolts may be ball
ended and have their said ends situated in similarly constructed sockets in the
shipside frame, the arrangement in either case enabling the glass holder or frame and
the inside or "dead" shutter to accomodate themselves to any variation or twist in
the shipside frame so as to form a water tight joint without the necessity of filing or
dressing the bearing or paring the rubber or other elastic packings. With the like
object the binding screws, by which the glass frame and inside or "dead" shutter
are held in closed position are furnished with nuts having two collars or washers
one of which is at the outside and the other at the inside of the frame and shutter,
the bearing surfaces, constituting arcs of circles working on each other after the
manner of a ball and socket arrangement. The inside collar or washer in turning
back the nut acts to force the frame or shutter away from the packing when cemented
thereto by heat or otherwise whilst the outer collar or washer acts to tighten up the
frame or shutter.

COMPLETE SPECIFICATION.
Improvements in Ships' Side Lights.
I, ALEXANDER ROBERTSON, of Danson Terrace, Carron in the County of Stirling,
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 :-
This Invention which relates to ships' side lights has for its object to provide
improved hinge and binding screw arrangements whereby, in closing the glass holder

page_text: and inside or "dead" shutter, the pressure or strain is uniformly distributed all round
the water-tight bearing the said improved hinge in its principal arrangements being
also adjustable to suit any slight variation in the thickness of the rubber or other
elastic packing of the watertight bearing so as to obviate danger of the frames
becoming hinge bound and of fracturing the glass in closing or screwing up the
light.
The Invention is illustrated under one modification in front elevation at figure 1,
in side elevation at figure 2, and in transverse section at figure 3, sheet 1, of the
accompanying drawings and as seen by these figures there are cast on or secured
to the frame A, which is inserted into the ship's side, two sets of jaws or lugs, one
set B, being provided to carry the glass holder or frame C, and the other set D, to
carry the inside or "dead" shutter E, Through each set of these jaws or lugs there
passes a pin or stud F, on which is centred a connecting piece G, constituting a
swivel joint and hinge and through the upper end of each of these connecting pieces
there passes another pin or stud H, at right angles to the pin or stud F, the pins or
studs H, also passing through binge screws or bolts I, and through slotted holes x,
made one in the glass holder or frame C, and the other in the inside or "dead" shutter E.
The screws or bolts I, are furnished with nuts J, these, besides being threaded on to
the bolts, being tapped one into the glass frame C, and the other into the "dead"
light or shutter E, and by turning the said nuts the pressure on the india-rubber or
other elastic packing K, of the frame and shutter is regulated. The nuts J also
make provision for wear or inequality in the thickness of the packing, whilst the
pins F, and connecting pieces G, enable the glass frame and the "dead" shutter to
accomodate themselves to any variation or twist in the frame A, so as to form a
watertight joint without the necessity of filing or dressing the bearing or paring
the rubber or other elastic packing.
Figure 4, sheet 1, illustrates in front elevation, figure 5 in side elevation and
figure 6 in transverse section a modification of the improved joint in which the
connecting piece G, is dispensed with the hinge screws I, being centred upon the pins
or studs F, and connected as before by pins or studs H, to the frame C, and "dead"
shutter E. With this arrangement a bridge L, rests upon the connecting lugs M, of
the frame and shutter the said bridges serving as abutments for the nuts J, regulating
the pressure on the india rubber or other elastic packing.
Figure 7, illustrates in side elevation and figure 8, in transverse section a
modification of the improved hinge in which besides the connecting piece G, the
pin F, is also dispensed with the pin H, passing through lugs B, formed on the
frame A, and through a lug L, on the glass frame C, which is placed between
the lugs B, and has its end made in the form of a bridge. The hinge screw I,
situated on the pin H, has its nut tapped through the upper part of the bridge, the
holes in the side of which, for the passage of the pin, are slotted to enable the
pressure on the packing to be regulated. The same arrangement is also applied to
the "dead" shutter when such is used.
Figures 1, 2, and 3, sheet 2, illustrate a further modification of the improved
compensating hinge as applied to a side light frame C, and in which the screw I, is
formed on or fixed in a heel or block N, projecting from the frame A. Through a
slotted hole in the said block the pin H, carrying the frame C, passes the said pin
also carrying a bridge L, into which a nut J, threaded on to the screw I, is tapped and
by turning the said nut the pressure on the packing K, is regulated. Figures 9, and
10, sheet 2, illustrate in side elevation and in transverse section respectively the same
arrangement with the screw I, centred on a pin F, instead of being formed on or
secured to the frame A.
Figures 4, 5, and 6, sheet 2, illustrate a modification of the improved hinge as
applied to a side light and in which the screw I, with its nut J, is dispensed with the
construction being otherwise practically similar to that shewn by figures 1, 2, and 3,
sheet 1, that is to say, a connecting piece G, is centred upon a pin or stud F, and
attached to the side light frame C, by a pin or stud H at right angles to the
pin F.

page_text: "dead
Also with the object of enabling the glass frame C, and the inside or
shutter E, to accomodate themselves to variation or twist in the ship's side frame A,
the binding screws R, by which the frame C, and "dead" shutter E, are held in
closed position are, as seen at figures 1, 2, and 3, sheet 1, furnished with nuts having
two collars or washers P, P¹, the collar P, being at the outside and the collar P1, at
the inside of the frame and shutter. The inside collar or washer P¹, in turning back
the nut acts to force the frame or shutter away from the packing when cemented
thereto by heat or otherwise whilst the outer collar or washer acts to tighten up the
frame or shutter. The nut may be a thumb nut as shewn on sheet 1 or it may be a
paned nut as at figure 7, sheet 2, in which case it is turned with a key.
In order that the binding screws R, may more completely accomodate themselves
with the frame C, and shutter E, they may as seen at figure 8, sheet 2, be ball ended
and have their said ends situated in a similarly constructed socket in the frame A, and
with this arrangement the form of nut o, seen at figure 6, sheet 2, may be adopted
the said nut having its bearing end made partly spherical the said end resting in a
correspondingly formed washer S.
In the arrangement of hinge figures 4, 5, and 6, sheet 1, instead of connecting the
hinge screw I, to the frame A, by a pin F, the screw may have a ball end working
in a socket in the frame A.
Having now particularly described and ascertained the nature of the said
invention 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 several arrangements of hinge hereinbefore described
with reference to the drawings annexed.
2. In a hinge for ships' side lights the use of a screw I, substantially as and for
the purposes herein before described with reference to the appended drawings.
3. In a ship's side light the binding arrangements herein before described with
reference to figures 1, 2, and 3, sheet 1, and figure 7, sheet 2, of the appended
drawings.
4. In a ship's side light the combination of a binding screw, ball ended or not, a
nut thereon having a partly spherical bearing surface and a correspondingly formed
washer resting on the frame to be bound substantially as described with reference to
the accompanying drawings.
