Improvements in and relating to Side Lights and Ventilators for
Ships and other Analogous Purposes.
I, EDMUND SHARER, of 8, Belhaven Crescent, Kelvinside, in the County of the
City of Glasgow, Manager, do hereby declare the nature of my invention to be
as follows:
This invention has reference to and comprises improvements in and relating to
side lights and ventilators which may be combined in one frame for ships and other
analogous purposes, and consists of means for conveniently securing the side lights
in a weather tight manner, and of improvements in the construction of ventilators
whereby they may also be closed weather tight when desired.
Though more especially designed for use in connection with a combined ship's
side light and ventilator for use in deck houses, or the like, it is to be understood
that the securing devices are equally applicable to lights or casement windows
otherwise situated, and the ventilating devices are also capable of being employed
separately either on board ship, or otherwise, in doors or elsewhere where such
ventilators are applicable.
As applied to a combined side light and ventilator for a ship's deckhouse the
securing devices are constructed as follows:-
The side light preferably rectangular in shape, but which may be of round or
other form, hinged at one side in the usual manner and provided with a strip of
rubber or analogous material to make a weather tight joint when pressed against
the inwardly projecting rim of main frame, has formed on or secured to the inside
of its rim opposite the hinged part two segmental wedge pieces or inclined planes
which are acted on by the free ends of small bell crank levers pivotted on the main
frame. Right and left hand screws are jointed to the other ends of the bell crank
levers and screw into the two ends of a hollow handle for turning by hand, or it
may be by a key, which is supported in position by a slotted bracket projecting
from and secured to the main frame. The upper end of the hollow handle projects
through the slot in the bracket and the handle is supported in position by a nut
screwed on or otherwise secured to its upper end, and bearing on the bracket.
order to secure the light in position when opened to its fullest extent that part of
the lower hinge secured to the main frame is formed with a check and a projection
formed on the part of hinge secured to light frame abuts against said check and a
pin is passed through holes in both of these parts to hold the light in its open
position.
In
When it is desired to prevent the side light being opened by turning the hollow
handle by hand a small clip or catch may be pivotted on the main frame and
when turned over the edge of side light frame this clip is secured by screwing up
a nut on its pivotting stud by means of a spanner or key. These securing devices
may be employed for other lights of an analogous construction or for casement
windows otherwise of an ordinary construction."
The ventilator when used in combination with a sidelight consists of perfora-

page_text: tions or fretwork which may be of semi-circular or other shape desired, formed
or secured in the upper part of the main frame of light. Around this fretwork the
frame has an inwardly projecting rim converging to a circular opening in the
centre, where the rim is formed with a flange to which is secured by screws a flat
ring carrying a bridge piece. This bridge piece is formed with a nut at its centre
part through which works a screw carrying at its outer end a disc slightly dished
inwards which forms a door to close the circular opening of ventilator when screwed
home.
The flat ring of the bridge piece may have an annular projection and the door
a rubber or like strip to form a weather tight joint when pressed together by the
screw which may have a small hand wheel on its inner end. A small opening
may be formed at lower part of ventilator to allow any water entering to flow out.
By another and converse arrangement the perforated fretwork may have a
screwed bolt formed on or secured to it projecting within the converging rim of
ventilator and the closing door be formed on the inner end of a nut working on
this screw to close the circular opening as desired.
Either of these forms of ventilator may be used in combination with a sidelight
or separately either on board ship or elsewhere where applicable.

Improvements in and relating to Side Lights and Ventilators for
Ships and other Analogous Purposes.
I, EDMUND SHARER, of 8, Belhaven Crescent, Kelvinside, in the County of the
City of Glasgow, Manager, do hereby declare the nature of my invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement, in writing reference being made to the
accompanying sheet of drawings:-
-
This invention has reference to and comprises improvements in and relating to
side lights and ventilators which may be combined in one frame for ships and
other analogous purposes, and consists of means for conveniently securing the
side lights in a weather tight manner, and of improvements in the construction
of ventilators whereby they may also be closed weather tight when desired.
Though more especially designed for use in connection with a combined ship's
side light and ventilator for use in deck houses or the like, it is to be understood
that the securing devices are equally applicable to lights or casement windows
otherwise situated, and the ventilating devices are also capable of being employed
separately either on board ship or otherwise, in doors or elsewhere where such
ventilators are applicable.
And in order that my said invention and the manner of carrying the same into
effect or practice may be properly understood I have hereunto appended a sheet
of explanatory drawings in which Figure 1 is an elevation of a combined side
light and ventilator, Figure 2 a side elevation partly in section and Figure 3 a
sectional plan of the same, while Figure 4 is an outside view showing the upper
part of frame and the ventilator, and Figures 5 and 6 are respectively a front and
side sectional view of a modified form of ventilator.
As applied to a combined side light and ventilator for a ship's deckhouse and as
illustrated by Figures 1 to 4 of the drawings the securing devices are constructed
all as follows:-

page_text: The side light A preferably rectangular in shape, but which may be of round or
other form is hinged at one side in the usual manner and provided with a strip
of rubber or analogous material a to make a weather tight joint when pressed
against the inwardly projecting rim a¹ of main frame A and has formed on or
secured to the inside of its rim opposite the hinged part two segmental wedge
pieces or inclined planes a² which are acted on by the free ends of small bell crank
levers B pivotted on the main frame A¹. Right and left hand screws C are
jointed to the other ends of the bell crank levers B and screw into the two ends of
a hollow handle 1) for turning by hand, or it may be by a key, which is supported
in position by a slotted bracket E projecting from and secured to the main
frame A. The slot e shown in Figure 3 allowing the necessary lateral move-
ment of the upper screw within it. The upper end of the hollow handle D pro-
jects through the slot e in the bracket E and the handle D is supported in position
by a nut screwed on or otherwise secured to its upper end, and bearing on the
bracket E. In order. to secure the light in position when opened to its fullest
extent that part F of the lower hinge secured to the main frame A¹ is formed with
a check and a projection formed on the part FI of hinge secured to the frame of
the light A abuts against said check and a pin f is passed through holes in
both of these parts to hold the light in its open position.
When it is desired to prevent the side light being opened by turning the hollow
handle by hand a small clip or catch G is or may be pivotted on the main frame A¹
and when turned over the edge of the frame of the light A this clip G is secured
by screwing up a nut g on its pivotting stud g¹ by means of a spanner or key.
These securing devices may be employed for other lights of an analogous con-
struction, or for casement windows otherwise of an ordinary construction.
The ventilator when used as shown in combination with a side light A consists
of perforations or fretwork H shown in Figure 4 which may be of semi circular
or other shape desired, formed or secured in the upper part of the main frame A¹.
Around this fretwork H the frame has an inwardly projecting rim H¹ converging
to a circular opening in the centre, where it is formed with a flange h to which is
secured by screws a flat ring h¹ carrying a bridge piece h². This bridge piece is
formed with a nut h³ at its centre part through which works a screwed spindle I
carrying at its end a disc I slightly dished inwards which forms a door or valve
to close the circular opening of ventilator when screwed home.
The flat ring of the bridge piece has an annular projection h and the door a
rubber or like strip i to form a weather tight joint when pressed together by the
screwed spindle I which has a small hand wheel ¹ on end. A small opening may
be formed at lower part of ventilator to allow any water entering to flow out.
By another and converse arrangement illustrated by Figures 5 and 6 of the
drawings the perforated fretwork H has a screwed bolt I formed on or secured to
it projecting from within the converging rim H¹ of ventilator and the closing door
or valve I is formed on the inner end of a nut I2 working on this screwed bolt I
to close the circular opening as desired.
Either of these forms of ventilator may be used in combination with a side light
or separately either on board ship or elsewhere where applicable.
Having now particularly described and ascertained the nature of my said
nvention and in what manner the same is to be performed I declare that what
claim is:
First. The construction or arrangement and combination of the parts of a com-
ined light and ventilator all substantially as herein described in reference to and
lustrated by the accompanying drawings.
