PROVISIONAL SPECIFICATION.
Improvements in and relating to Appliances for Operating the Venti-
lating Side-lights of Ships' Cabins, Roof-lights, and the like.
I, EDMUND SHARER, of 8, Belhaven Crescent, Kelvinside, in the County of the
City of Glasgow, Shipbuilder, do hereby declare the nature of my invention to
be as follows:-
This invention has reference to improvements in and relating to appliances for
operating the ventilating side-lights of ships' cabins, the roof or fan-lights of
buildings, and the like.
As applied to the side lights of ships' cabins, each window frame would be
swung or mounted at the centre part of their ends on oscillatory crank or ☐ shaped
arms carried on pins in fixed end brackets, while the lower ends of these frames
would have projecting pins working in vertical or curved slots formed in said
brackets. Curved links would have their one ends mounted on pins carried on
lugs a short distance from each side of the lower centre part of the window frame,
and the other ends of these links would be carried on pins projecting from a central
internally screw threaded nut. This screwed nut would be mounted over a screw
threaded worm or spindle carried in bearings in a fixed bracket and turned by a
hand crank at lower end. By turning this crank handle in the one direction
the window frame will through the screw action curved links, pins working in
slotted bracket and oscillatory arms, be swivelled within the ship's cabin to venti-
late same, while by reversing the turning motion of crank handle, the window frame
will be closed. Dovetail or other blocks of rubber would be fitted all round the
side-light frame to bear as a cushion on the window port frame secured to side
plating of ship.

Improvements in and relating to Appliances for Operating the Venti-
lating Side-lights of Ships' Cabins, Roof-lights, and the like.
I, EDMUND SHARER, of 8, Belhaven Crescent, Kelvinside, in the County of the
City of Glasgow, Shipbuilder, do hereby declare the nature of my invention, and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement, that is to say:-
This invention has reference to improvements in and relating to appliances for

buildings, and the like.
And in order that my said invention and the manner of carrying same into
practice may be properly understood I have hereunto appended a sheet of explana-
tory drawings in which the same reference letters are used to indicate corres-
ponding parts in all the figures where shown. Figure 1 is a front elevation and
Figure 2 a corresponding side elevation of the ventilating side-light of a ship's
cabin as fitted with my improved operating appliances. Figure 3 is a detached
plan of the bracket and fittings as taken on the line 3-3 of Figure 1, while
Figures 4, 5, and 6 are plan views as taken on the lines 4-4, 5-5, and 6-6,
respectively of Figure 1.
Referring to these drawings:
As applied to the side lights of ships' cabins, each window frame A would be
swung or mounted at the centre part of their ends on oscillatory crank or L shaped
arms A¹ carried on pins A2 in fixed end brackets A³, while the lower ends of these
frames A would have projecting pins A+ working in vertical or curved slots A5
formed in said brackets A³. Curved links B would have their ends mounted on
pins b carried on lugs b¹ a short distance from each side of the lower centre part
of the window frame A and the other ends of these links B would be carried on
pins projecting from a central internally screw threaded nut B'. This screwed
nut B would be mounted over a screw threaded worm or spindle B2 carried in
bearings B3 in a fixed bracket B and turned by a hand crank 15 at lower end.
By turning this crank handle B in the one direction the window frame A will
through the screw action of curved links B, pins A+ working in slotted bracket A³
and oscillatory arms A¹ be swivelled within the ship's cabin to ventilate same as
shown in the dotted position in Figure 2 while by reversing the turning motion
of crank handle B the window frame A will be closed as shown in the full line
position in Figure 2. Dovetail or other blocks of rubber C would be fitted all
round the side light frame A to bear as a cushion on the window port frame C
secured to side plating of ship.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
First. The arrangement in combination of the appliances for operating the ven-
tilating side-lights of ships' cabins, roof-lights, and the like, substantially as here
in described in reference to and shown in the accompanying drawings.
Second. In connection with the ventilating side-lights of ships' cabins, roof-
lights, and the like, the combination of oscillatory arms A¹, pins A working in
slotted bracket A³, curved links B, and a screw and nut or equivalent action,
substantially as herein set forth.
