We, EDWIN JAMES PRESTON of the firm of J. Stone & Co. of Deptford in the
County of Kent Engineers and EDWIN WILLIAM DE RUSETT of 2 Fell Road
Croydon in the County of Surrey Civil Engineer do hereby declare the nature of
this invention to be as follows :—
This invention consists in improvements relating to the mode of attaching and
opening and closing of the glass door and of the dead door in side scuttles and port
lights for ships and has special reference to constructions of same shewn and
described in Mullan's Patent Specification No. 8614 of 1886 and Preston and
De Rusett's Patent Specification No. 11253 of 1886. Instead of using the com-
pression ring H described in the latter Specification for ensuring a watertight
joint for the horizontally or vertically pivoted glass door we form a V shaped or
narrow edge on the inside rim of the glass door as well as on the frame in which
the door is pivoted and which is fixed to the skin of the ship and we provide an
open frame (or it may be a dead door) which is hinged to the said fixed frame
and which is formed with an annular recess for a rubber or other suitable joint ring
forming a seating for the two aforesaid V edges. This open frame or dead door is
fastened to the fixed frame by hinge screw bolts or other suitable means.
For actuating the aforesaid compression ring H (which special reference to
Figures 10 and 11 in that Specification) we sometimes use a pinion that gears
with teeth formed on or attached to the compression ring which may also be formed
with inner slanting projections for holding the glass door in place the said door
Also in order to
having a corresponding lug sliding between the projections.
prevent corrosion or other injurious action on that part of the glazed gun metal
frame A which is in contact with the india rubber ring G we provide the said part
with a ring of ebonite, celluloid, white metal or other suitable material. In the form
of side light shewn in Figures 14 and 15 instead of the compression ring in two
halves we use one made in one piece like a band fixed at one end, the other end
being capable of tightening up around the rubber packing ring, which latter may be
round in section and with rolling packing action or contained in a wedge shaped
TACASS

page_text: In sido lights for ships of war we so arrange the glass door and the dead door that
the latter can be scrowed down upon the former when requirod, but so that the
glass door can also when desired he hinged back by itself and thus avoid the
destructive offect of concussion caused by the discharge of heavy guns. For this
purpose and to enable the glass door to be thus swung back we attach the dead
door of the side lights and port lights described in the aforesaid Specifications and
the dead door of other constructions of side light and port light where such is
practicable, to a screw spindle which is fixed in the centre of the dead door and
passes through a nut capable of turning in a cross bar or bridge which at one end is
pivoted to the fixed frame and at the other end can be secured thereto by a hinge
bolt with bow nut. The bridge may suitably be of cast steel. By means of a hand-
wheel on the nut the latter is turned for making or unmaking the joint between the
dead door and the glass door, or (if the latter is swung out of the way during
firing of the gun) for making or uninaking the joint between the dead door and the
fixed frame, the dead door being provided with a rubber or other joint ring which
comos against an annular projection on the glass door or the fixed frame as the case
may bo. The glass door has a rubber or other joint ring which forms joint with
the annular projection on the fixed frame. Or vice versu we may have the nut fixed
in the dead door and the screw spindle would then turn in the bridge.
The glass door when fitted in connection with a dead door and bridge of this
description is in some cases attached to the fixod frame by a hinge at one side and
provided with a hinge screw fastening or clip at the other side and the brackets for
the hinge and for the hinge scrow on the fixed frame may be made alike or inter-
changeable so that the glass door may be fitted either right handed or loft handed.

page_text: We, EDWIN JAMES PRESTON of the firm of J. Stone & Co. of Deptford in the
County of Kent Engineers, and EDWIN WILLIAM DE RUSETT of Fell Road
Croydon in the County of Surrey Civil 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 consists in improvements relating to the mode of attaching and
opening and closing of the glass door and of the dead door in side scuttles and
Port lights for ships, and has special reforence to constructions of same, shewn
and described in Mullan's Patent Specification No. 8614 of 1886 and Preston and
De Rusett's Patent Specification No. 11253 of 1886.
These side scuttles and port lights are particularly useful when applied to large
passenger ships, troop-ships and war-ships and offer great advantages as to facility for
quickly opening and quickly and tightly closing, and as to strength so that they can
be made largo and thus afford increased light and ventilation. When applied to war-
ships the glass door is not damaged by discharge of heavy guns.
Instead of using the compressing ring H described in the Specification No. 11253 of
1886 for ensuring a water-tight joint for the horizontally or vertically pivotted glass
door we construct the parts in the manner shewn in Figures 1, 2, 3 and 4, Figure 1
being a view of the scuttle from the inside of the cabin, Figure 2 a vertical section,
Figure 3 a section on line A D and Figure 4 a perspective view of the scuttle with
the glass door open. We form the inside rim or the inside as well as the outside rim
of the glass door A as well as the frame E in which the door is pivotted and which is
fixed to the skin of the vessel each with a rounded V shaped or narrow edge a
and e respectively and we provide an open frame M as shewn in Figure 3, or a dead
door Mas shown in Figure 2 which is hinged to the said fixed frame E. This open
frame or dead door is formed with an annular recess for a rubber or other suitable
joint ring m forming a seating for the two aforesaid ✓ edges a and e.
The open
frame M or dead door A1 is fastened to the fixed frame E by hinge bolt and lugs or
other suitable hinge appliance. The dead door M' may as here shewn be made in the
form of an outer rim and an inner removable lid, or it may be made all in one casting.
For actuating the aforesaid compression ring H with special reference to Figures 10)
and 11 in the said Specification No. 11,253 we use as here shown a pinion I provided
with crutch handle 1 and that gears with teeth formed on (or it may be attached to)
the compressing ring H. This latter is formed with inner slanting projections or
cleats H in this case five of them for holding the glass door A in place, the door
frame having corresponding wedge shaped lugs under which they take and thus
hold the joint ring m tightly up against the V shaped edges a and e. The glass door A

page_text: is mounted in pivots arranged at two opposite sides, one pivot A' being screwed into a
socket on the frame E and capable of adjustment while the other pivot A' which is
screwed into the glass door frame A has an elastic end bearing against the helical
spring A. The glass pane B in the door A is hy the ring B' screwed up against the
rubber ring 1 in the usual manner.
Figure 4 is inside view and Figure 4 vertical section of a modified form of
pivoted side scuttle or port light in which the glass door A is formed with the
edge on one side or as proferrod and here shown on both sides) and making joint
against the rubber ring m in an open hinged frame M (or it might be a dead door).
But instead of the rotatable compression ring H and wedge shaped cleats we in this
case tighten the frame or door M. down by means of ordinary swing bolts N passing
through lugs cast on the frame or door M and by the bow nuts O.
Figure 5 is inside view figuro 6 horizontal section and Figure 7 vertical section
through another form of side scuttle with pivotted glass door without a dead door
and where the compression ring E serves to compress the circular (or other) rubber
ring G for making a tight joint round the pivotted glass door A. The ring H is
furnished with teeth and is turned by means of a pinion I gearing thorowith. The
recess for the pivot spring A has a lateral cover A
The
Figures 8, 9 and 10 shew the same means for turning the compression ring H but
applied to a hinged glass door, Figure 8 being an inside view partly in section
Figure 9 a vertical soction and Figure 10 a cross section on lino AB.
frame E has a Vodgo a which can make joint against the rubber ring m in the
compression ring E when the lattor is turned into such a position that the wedge
shaped lugs or clents H thereon come under the lugs Ex on the frame E, the
turning movement being effected by the pinion I with crutch handle 1' the pinion
gearing with teeth on the compression ring H. The door A which is also provided
with a compression ring H is hinged to the framo E by hingo pin Land lugs. Also
in order to prevent corrosion or other injurious action on that part of the glazed gun
metal frame A which is in contact with the India rubber ring G we sometimes as
shown in the sectional view Figure 11 provide the said part with a ring A* of
ebonite celluloid white metal or other suitable material.
In the form of sido light with pivotted glass door shewn in Figures 14 and 15 of
the said Specification No. 11253 of 1886 instead of the compression ring in two
halves we use an arrangement such as shown in Figures 12, 13, 14 and 15 Figure 12
being an inside view Figure 13 a horizontal section Figure 14 a vertical section and
Figure 15 a section on line A B. In this arrangement the compressing ring H is
made in one piece like a band fixed at one end by a lug H held in a slot in the
lug on the framo E the other end by means of the screw K passing freely through
the lug of the band H and screwing into the lug E being capable of being
tightened up thus causing the ring H to compress the rubber packing ring G which
as shewn may be round in soction and it might be with rolling packing action or be
contained in a wedge shaped recess. The ring His held in place on the frame E
by means of the cleats E. If this side light is fitted with an inner dond door M.
it may be connected by a hingo at one side as shown and an eye bolt N with
nut (.
In side lights for ships of war we so arrange the glass door and the dead door that
the latter can be screwed down upon the former when required but so that the glass
door can also when desired be hinged back by itsolf and thus avoid the destructive
effect of concussion caused by the discharge of heavy guns. For this purpose and to
enable the glass door to be thius swung back we construct the side lights and port
lights described in the aforesaid specifications and the dead door of other constructions
of side lights and port lights where such is practicable in the manner shown in
Figures 16, 17 and 18 which are respectively insido viow horizontal section, and
vertical section, Figure 18 showing the dead door secured upon the closed glass
door and Figure 17 showing the glass door turned in to be out of the way and the
dead door secured upon the frame.

page_text: The dead door M is fixed in the centre to a spindle P which is capable of turning
in its bearing in the door M being for this purpose provided with a handle P' and
passes through a nut fixed or formed in a cross bar or bridge Q which at one end is
pivotted to the fixed frame E, and at the other end can be secured thereto by a hinge
bolt N with bow nut O. The bridge Quay suitably be of cast steel. By means of
the handle P' on the screw spindle the spindle is turned for making or unmaking the
joint between the dead door M and the glass door A as shown in Figure 18 or (if the
latter as shown in figure 17 is swung out of the way during firing of the gun) for
making or unmaking the point between the dead door M and the fixed frame É the
dead door being provided with a rubber or other joint ring m which comes against
an annular projection a on the glass door A or as shown in figure 17 against the
fixed frame E as the case may be. The glass door A has a rubber or other joint
ring a which forms joint with the annular projection on the fixed frame. Or
vice versa instead of having the nut formed or fixed in the bridge Q we may have
the nut made to turn in its place in the bridge Q by means of a handwheel on
the nut and the screw spindle P would then be fixed in the door M and means
would be provided for preventing the door from turning round while being raised
from or lowered upon its seat. The glass door when fitted in connection with a
dead door M and bridge Q of this description is in some cases and as here shown
attached to the fixed frame by a hinge at one side and provided with a hinge screw
fastening NO or clip at the other side and the brackets R for the hinge and for the
hinge screw on the fixed frame may as shown be made alike or interchangeable so
that the glass door may be fitted either right handed or left handed.
Figures 19 and 20 are inside view and vertical section of another arrangement of
dead door and glass door but both being as in the previous example hinged one
of them vertically and the other horizontally so that one or other inay be fastened
down. In this case the glass door is hinged at the top of the frame E and is secured
thereto by a compression ring H provided with teeth and gearing with a pinion I as
in previous examples the wedge lugs Ex on the frame E engaging with the
corresponding wedge lugs on the ring H just as shown in figure 9 which also forms a
vertical section of figure 19. The dead door M has a precisely similar compression
ring H as shown in figure 20 and also similar wedge lugs. The pinion I gears with
the teeth of either of these rings thus securing the glass door or the dead door in place,
the other door being then turned up, or in, out of the way.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First: The application to the fixed frame of a side scuttle or port light of a
pinion gearing with teeth on a compression, ring, rotatable on the glass door, dead
door or open frame for the purpose of turning the said ring and thus by means of
wedge pieces engaging with wedge cleats making tight joint between such doors and
frames substantially as set forth.
Second-The construction of side scuttle and port light in which the scuttle frame
and the glass door pivoted thereto are provided with V edges for forming joint with a
joint ring on a hinged dead door or open frame substantially as described with
reference to figures 1, 2, 3, 4, 4* and 4B.
Third: The construction of side scuttle and port light with pivoted glass door
substantially as described with reference to Figures 5, 6 and 7.
Fourth-The construction of side scuttle and port light with hinged glass door
substantially as described with reference to Figures 8, 9 and 10.
Fifth-The construction of pivoted glass door described with reference to
Figure 11.
Sixth-The application to the fixed frame of a side scuttle or port light of a
band shaped compression ring which is fixed at one end and can be pulled up at the
other end for the purpose of making joint with the glass door substantially as described
with reference to Figures 12 to 15.

page_text: Deventh The application to side scuttles and port lights of a glass door and a
dead door hinged at right angles to each other so that one or the other (or both) may
be fastened door substantially as described.
Eighth-The construction of side scuttles and port lights substantially as described
with referonco to Figures 16 to 20 and 9.
