PROVISIONAL SPECIFICATION.
Improvements in and connected with Ships' Side Lights.
I, ROBSON BROWN of 42 Cromwell Street, Millfield, Sunderland in the County
of Durham, Patternmaker, do hereby declare the nature of this invention to be as
follows:-
My invention relates to ships' side lights and the like and has for its object to
provide simple and efficient means for ensuring better ventilation in all weathers
without danger of leakage at the light and to provide for adjustment of the
ventilation as required.
:
According to one part of my improvements I hinge to the upper part of the
fixed frame of the light a stirrup or equivalent appliance the side members of which
may follow the configuration of the frame and extend concentrically around its
upper part for a suitable distance.
:
In the lower ends of the stirrup äre centred the pivots of the frame of a rotatable
glass light and means such as lock bolts are provided and localised in suitable
positions for locking all the parts separately or together in closed positions as and
when required and to press the door against an interposed rubber ring, to ensure a
water-tight joint.
By pulling out the stirrup and rotating the glass door to any angle after the
requisite locking appliances have been unfastened and part thereof refastened, the
degree of ventilating opening may be adjusted.
Furthur in connection with an arrangement such as is herein referred to and for
the purpose of procuring automatic ventilation when the light is shut and fixed
down as in stormy weather I form in the frame of the light a series of, valve
controlled air ways or passages governed by a suitably fitted grid or similarly,
constructed plate or ring.
++
The valves controlling these passages are preferably cork plugs or floats of
suitable kind and size and these are fixed onto rubber flaps forming a part of or
projection from a packing ring inserted between the glass and frame to secure a
watertight joint.

SPECIFICATION.
Improvements in and connected with Ships' Side. Lights.
I, ROBSON BROWN, of 42 Cromwell Street, Millfield, Sunderland, in the County
of Durham, Patternmaker, 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 relates to improvements in and connected with ships' side lights
and has for its object special means for facilitating the making and maintaining of
watertight joints in connection with such appliances as well as to afford better
ventilation in rough weather without leakages at the lights.

page_text: which
I will describe my invention with reference to the accompanying drawings in
Figure 1 shows a front view of a light (without a dead door) with all parts closed,
Figure 2 being a plan view of the same apparatus but with all the parts open as
hereinafter described.
Figure 3 shows a back elevation of the stirrup hinge and locking device shown
in Figure 1.
Figure 4 shows (top half) half front and (bottom half) half back views of
casement with ventilating device arranged around the circumference Figure 5
showing sectional elevational. view (top half) and end elevational view (bottom
half) of Figure 4 and in the following description like marks of reference designate
⚫like parts.

Referring to the drawings (Figures 12 and 3) the glass door or casement 8 is
pivoted at 9 in a stirrup 10, the stirrup itself being mounted on pin 11 in
Jaws 12.
The casement is fitted with locking lugs at 13 and 14, the swing bolt 15 when
the casement is shut serving to compress the edge 16 against the rubber ring 17
while the screw bolt 18 with fixed stops 19 thereon serves to receive the lug 14 and
to either compress the casement against its.rubber .ring. 17 or to ease it therefrom
as desired. An additional swing bolt 20 is provided as shown to lock the stirrup
(fitted with lugs 21) in any desired position. It will thus be seen that instead of
having a fixed hinge to the casement at one side as is usually the case and a locking
bolt at the opposite side I employ a hinged stirrup whereby the casement pivoted
therein can be tightened up or slackened at the opposite sides by respectively
bolts 18, and 15 and in this manner 1 can, ensure inuch greater security against
leakages.
Furthur by the arrangement described the stirrup can be swung out as shown in
Figure 2 and there locked if desired while the casement therein can be swung
round, on its pivot and locked if desired as shown. The dot and dash lines in
Figure 2 indicate another position that can be readily assumed by the casement.
The plate P is intended to act as a. director of the air current in aid of
ventilation.
.
Referring now to Figures 4 and 5 in order to provide for ventilation in stormy
weather when ordinarily all lights are tightly screwed down I form a frame such
as 22 (which may be pivoted in the ordinary manner or as herein described) to
contain the glass 23 and between the outer edge of the glass and frame. I form a
series of openings 24 divided. from.one another preferentially by ribs such as 25.
In a circumferential recess of this frame 22 I fit a thin india rubber ring 26 and
thereonto opposite each opening 24 and adapted to fit same I secure a cork plug or
float or flap valve such as 27. To the frame 22 I secure by screws or otherwise
the frame 28 having openings 29 therein corresponding to the openings 24 aforesaid
and on a projecting screwed flange 30 of this frame 28, I mount the frame 31 also
fitted with openings adapted, to correspond with those on the other frames and with
knobs 32 for turning it as required.
Thus by so turning frame 31 as to bring the openings therein opposite the other
openings in the other frames, air, can freely pass the flap valves or floats 27 and
should a wave strike the light the flap valves or floats will be automatically closed
thereby so as to prevent ingress-of water and then re-open to again admit air and
if desired the frame 31 can be so turned as to bring its solid surfaces over the
openings in the other frames to close them altogether.
•
The invention is obviously applicable to engine room skylights, deck house
square windows and the like.
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. The provision in combination with ships' side' lights of a hinged stirrup

page_text: provided with a tightening or slackening bolt such as 18 the forked ends of the
stirrup having pivoted therein a frame adapted to revolve as required the several
parts being arranged disposed or adapted to work substantially as herein described
and illustrated in the accompanying drawings.
2. The combination with a glass casement frame such as 22 of circumferential
openings such as 24 therein fitted with adjustable flap valves such as 27 adapted to
close or open automatically substantially as herein set forth.
3. The provision in combination with the subject of Claim 2 of means for
closing the openings 24 by an adjustable ring such as 31 substantially as herein set
forth.
4. The provision in the forked ends of a stirrup such as is hereinabove described
and claimed in Claim 1 of a glass casement frame provided with means for
ventilation around its circumference such as is hereinabove described and claimed
in Claims 2 and 3 substantially as herein set forth.
