PROVISIONAL SPECIFICATION.
Improved Revolving Pivoted Lights for Lighting and Ventilating
Ships between Decks and Deck Houses.
JOHN SHAW. 22 Rosebill Terrace Willington-on-Tyne Northumberland
Ironfounder do hereby declare the nature of this invention to be as follows :-
:-
This invention relates to improvements in ships side lights and deck house lights
and is specially intended for passenger ships where a large amount of light and
ventilation is required.
My improved consists of frame, casement, gland, dead light and suitable fastenings
made of brass or other material.
The frame is secured to inside of ships shell and deck house shell and made
deeper than an ordinary frame, with a belt round inside to fit casement and
for gland to butt against and slide in to allow casement to revolve when
screwed back.
The casement which holds glass pivoted at top and bottom and arranged so
that the amount of opening can be regulated at will and machined a round edges
to fit inside of frame, the casement being pivoted, can be easily closed or
opened.
The gland is machined up to fit inside of frame and is provided with a recess at
inner end for a cushion made of india rubber or other material when screwed up
against the joint between frame and caseinent it makes it water tight all round,
and holds casement quite firm, when ventilation is required the gland is screwed
back to allow the casement to revolve, when set at the required angle for
ventilation, the gland is pressed against casement and holds it in position.
The dead light is hung in the ordinary way and is provided with a recess for
cushion when let down comes in contact with the end of gland, when screwed up
makes a perfect water tight joint all round.

I, JOHN SHAW 22 Rosehill Terrace Willington-on-Tyne Northumberland
Ironfounder 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:-
. 1
This invention relates to improvements in lights, and is specially intended for
passenger ships, where a large amount of light and ventilation is required.
My improved consists of frame, casement, gland or compression ring, dead light
and suitable fastenings made of brass or other material.
The frame is secured to inside of ships shell or deck house shell, and machined

page_text: up to fit casement, and gland or compression ring to butt against, and allow casement
to revolve when screwed or drawn back.
The casement which holds the glass is pivoted at top and bottom, and arranged
so that the amount of opening can be regulated at will, and machined up to
fit inside of frame, the casement being pivoted can be easily closed or opened.
The gland or compression ring is machined up, and is provided with a recess at
inner end, for a cushion ring made of india rubber or other material, when screwed
up against the joint between the frame and casement on a level face, or on a
convex face, it makes it water tight all round, and holds casement quite firm.
When ventilation is required the compression ring is unscrewed and drawn back
to allow the casement to revolve, when set at the required angle, the com-
pression ring is pressed against the casement, and with one turn of screw handles
holds it in position, when closing again the screw handles are turned back, and
loses the casement, when turned on a line with frame, the compression ring is
pressed back against the joint with one turn of screw handles it is made secure.
The dead light is hung in the ordinary way, and provided with a recess for a
cushion ring, when let down comes in contact with a projection on compression
ring, when screwed up makes a water tight joint.
The fastenings can be made as per drawings, or with the screw bolts screwed
into frame and the bosses to slide on the fixed bolts, with slots.
In the accompanying drawings
Fig. 1 is a front elevation of light showing screwed handles E. glass casement F.
and gland or compression ring M.
Fig. 2 is a sectional elevation showing casement F. compression ring M. and
dead light.
Fig. 3 is a section of fastener for screwing compression ring M. against case-
ment F and frame H.
Fig. 4 is a section of fastener on line A. B.
Fig. 5 is a section of fastener on line C. D.
Fig. 6 is a plan of fastener showing slot J. in boss I.
Like letters of reference indicate corresponding parts throughout drawings.
F casement carrying glass which is pivoted at G. so that it can be revolved in
the frame H. On the frame H. are two or more bosses or projections I. which
have a slot or grove J. as shown in Figs. 4. 5. and 6. in which slides a screwed
bolt K. having a hooked end or projecting part L. which moves in the grove J.
The handle or fastener E. is attached to the compression ring M. and can revolve
freely in the horns on the gland or compression ring M.
The inside of handle E. is screwed to suit the bolt K. by which means the com-
pression ring M can be pressed close to the frame H. and the glass casement F.
and by the aid of india rubber or other packing, makes a water tight joint where
the frame H. and glass casement F meet.
To allow the glass casement F. to be revolved the handle E. is turned to raise
the compression ring M. a little, the bolt K. is then moved through one fourth of
a revolution by the handle N. fixed to bolt K. so to bring the projecting part L.
on the bolt into the position shown in Fig. 4 which allows the compression ring M.
to be drawn sufficiently forward so that the glass casement F may be revolved.
When set at the required angle for ventilation the compression ring M. is
pressed back against the casement F. with a single turn of the handle K. the
casement is secure.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed,. I declare what I
claim is―
1st. A gland or compression ring, which slides in and out, for making a water-
tight joint, on a level face, or on a convex face, over the joint between frame and
Cocomant

2nd. A fastening made as per drawings, or with the screw bolts screwed into
the frame, and the bosses to slide on the bolts fixed in the frame.
3rd. The construction of a ships side or deck-house light, substantially as
described with reference to Figures 1. 2. 3. 4. 5 and 6.
Dated 14th day of December 1894.
