Improvements in Side Lights for Steam Vessels and Ships.
PETER FYFE, of 23, Montrose Street, Glasgow, Sanitary Inspector, and
ALEXANDER PHILLIPS, of 17, Anderston Quay, Glasgow, Brassfounder, do hereby
declare the nature of this invention to be as follows:-
-
This invention has for its object to simplify the closing and securing of the
glazed frame of the windows of side lights or side scuppers attached to the hulls
of steam or other vessels, in such a manner as to ensure a speedier closing action,
and greater tightness and uniformity of joint than at present. To this end we
form the glazed frame with a square or V-threaded screw, cut out of its external
periphery, and fit thereon a correspondingly screwed ring, which engages with
the frame rivetted to the hull of the vessel. In carrying out the invention we
form the fixed or rivetted frame in the usual manner, with the ordinary india-
rubber ring inserted into an annular groove in the inner face of the frame. In-
stead of the usual lugs for the hinged bolts, we form on the inside periphery of
the fixed frame, just inside the india-rubber joint, a series of three or more sets
of teeth or projections, which are so designed as to be different in size, configura-
tion or pitch each from the others. On the screwed ring, which is fitted on to
the threads cut on the outer periphery of the hinged frame, there is cast, upon its
outer periphery at its outer edge, a small flange, out of which notches are cut
of the size, configuration or pitch corresponding to the teeth or projections of
the fixed frame, so that in a certain position, when the glazed frame is closed, the
notches come opposite to the corresponding projections or teeth of the fixed
frame, and then the window frame is ready to be tightened against the india-
rubber joints. This is done as explained hereunder:-On the outside periphery
of the screwed ring, on its inner edge, a rack is cast or fitted extending from the
horizontal central line of the window to a distance round the upper or lower
circumference sufficient to ensure the complete compression of the inner edge of
the hinged frame upon the india-rubber joint, when the rack is turned round.
To turn the rack the usual pinion (gearing with it) and handle are employed,
both being fixed to the hinged frame. When the handle is turned round, the
pinion gearing with the rack turns it and the ring, when the small flange cast
on its outer periphery passes under the sets of projections or teeth of the fixed
frame.
By the action of the screw the ring is driven hard against the teeth or pro-
jections of the fixed frame, and not being able to unscrew itself from the hinged
frame, it drives the window frame hard all round against the india-rubber pack-
ing of the fixed frame, thus securing a speedy, uniform, and secure water-tight
joint.

We, PETER FYFE, of 23, Montrose Street, Sanitary Engineer, and ALEXANDER
PHILLIPS, of 17, Anderston Quay, Brassfounder, both of the City of Glasgow,
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 has for its object to expedite and simplify the closing and secur-
ing of the glazed frame of the windows of side-lights or side-scuttles attached to
the hulls of steam ships or other vessels in such a manner as to ensure a rapid
closing action and uniformity and tightness of joint.
In carrying out the invention we form a glazed hinged frame having a square
threaded or a V threaded screw cut out of its external periphery, and fit thereon
a correspondingly screwed ring so formed that it engages with the fixed franie
of the side-light which is rivetted or bolted to the hull of the vessel. We explain
the methods adopted and the details thereof with reference to the drawings
annexed hereto :-
Figure I shews the side-light in part section.
Figure II shews it in plan.
Figure III shews the screwed ring in gear, and how it engages with the corre-
sponding parts. of the fixed frame.
Figure IV shews an alternative to Figure III.
In Figure I A A is the fixed frame rivetted to the vessel. B B is an annular
flange cast on the fixed frame, having on its inner periphery another small
flange which is cut or notched at C C at convenient distances. These notches
may be cut of equal or of unequal length or configuration on plan. D D is the
india-rubber ring which is embedded and fixed into an annular groove cut in the
fixed frame to receive it. EE is the screwed ring which is made so that its
inner periphery fits on to a corresponding male screw cut out of the outer
periphery of the glazed hinged frame F F. On the outer periphery of the
screwed ring E E there are fins or projections cast, G, G, which, when the
hinged frame is to be closed, are opposite the cuts or notches C C of the fixed
frame. H H is a segmental toothed ratchet attached to the screwed ring E E.
This segmental ratchet gears with a pinion wheel K K attached by a pin and
handle to the hinged glazed frame FF, the spindle being carried down and let
into a hole bored out of the boss X cast on the fixed frame. L L is the usual
hinge having on the lugs attached to the glazed frame holes bored out slightly
oval to permit of the glazed frame having free closing action when it is tightened
on to its india-rubber seat. On the hinge lug of the fixed frame there is a fin M
which fits in between two small pins screwed into the screwed ring E E when the
hinged frame is in a position to be opened. This prevents the hinged frame from
being turned either way until the hinged glazed frame F F is closed again.
The action of the side-light is as follows:-
When the hinged glazed frame is closed the fins or projections G G on the
screwed ring clear the corresponding notches C C cut out of the flange of the
fixed frame (see Fig. III) and permit the screwed ring to be turned round by
the ratchet and pinion so that the outer sides of the fins G G pass under the
inner surface of the small flange on the fixed frame and bear upon it. As the
screwed ring is driven round by the action of the ratchet and pinion, its fins
bear equally and tightly against the flange, and as the fins cannot become dis-
engaged from the small flange of the fixed frame the screwed ring E E along

page_text: with the hinged glazed frame F F are pressed inward equally and tightly against
the india-rubber joint D D embedded in the fixed frame A A.
Preferentially the screw threads formed on the ring and the hinged glazed
frame are double threads, so that a large pitch is obtained and the side-light is
closed with rapidity. The fins G G and the notches C C are by preference
made of unequal length as shown in Fig. III so that a whole turn or revolution
of the screwed ring would require to be given before it could be disengaged
from the flange of the fixed frame.
It will be obvious that if desired the fins or projections may be formed on the
fixed frame (see G₁ on Fig. IV) and the corresponding notches made on a flange
cast on the screwed ring as at C on Fig. IV to obtain the same result.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In side-lights or side-scuttles for steam ships and other vessels the forming
of a screwed ring engaging with a corresponding screw cut upon the hinged
glazed frame thereof, as above specified and set forth with reference to the
annexed drawings.
2. In side-lights or side-scuttles for steam and other vessels the forming of a
notched flange on the fixed frame thereof engaging with fins or projections on
a screwed ring attached to the glazed hinged frame for closing the same as above
specified and set forth with reference to the annexed drawings.
3. In side-lights or side-scuttles for steam and other vessels the forming of
a notched flange upon a screwed ring attached to the glazed hinged frame thereof,
the said flange engaging with fins or projections upon the fixed frame thereof
as above specified and set forth with reference to Figure IV of the annexed
drawings.
4. In side-lights or side-scuttles for steam and other vessels the combination
of a screwed ring upon the hinged glazed frame thereof, with a notched flange
and corresponding fins or projections, the said screwed ring being actuated by a
toothed ratchet and pinion wheel for the purpose above specified, and as set
forth in the accompanying drawings.
