Improvements in Pivoted Ship Side and Deckhouse Lights.
1, JOHN SHAW, 28, Rosehill Terrace, Willington-on-Tyne, in the County of
Northumberland, Ironfounder, and JOHN GRANTHAM, 54, Beaconsfield Street,
Blyth, in the County of Northumberland, Retired Plumber, do hereby declare
the nature of this invention to be as follows:-
It consists of outer case, inner ring, frame for glass, packing ring, screw pins,
bow nuts, and deadlight where required.
The object of our invention is to give free ventilation between decks, and a
more secure light in a rough sea.
The outer case is provided with a flange and spigot to secure it, to ships shell
and recesses for inner ring lugs.
The inner ring is provided with lugs to slide backwards and forwards iu
recesses in outer case, with screw pins fixed in lugs, and pivots for glass frame.
The glass frame is provide with a ring for securing glass into frame, and holes
to revolve on pivots in inner ring.
The packing ring is provided with a recess for india rubber or other packing
for making a water tight joint around the inside of outer case, over the joints of
inner ring and glass frame, and a flange for fitting over the end of outer case,
and secured with screw pins through the two, and lugs with holes for bow nut
screw pins, fixed in inner ring to work through.
When fixed in position the heavier the sea strikes the glass the tighter it
makes the joint around the inside of outer case, as it does not depend on the
bow nuts or hinge fastenings to yield to the force of the sea, in this case, as the
said how nuts only holds the glass light in position when open or close for
ventilation.
When ventilation is required, the said bow nuts are screwed back to end of
screw pins, then pressed outwards to force the said inner ring back carrying
the said glues light frame with it, to alow the glass frame to turn around clear of
the fixed packing ring, then turned to the angle required, to suit the current of
air required for ventilation, when screwed back against packing ring it is held
in position by bow nuts.
When closing again the bow nuts are unscrewed to allow the glass to turn in
position again for closing, then drawn or screwed back with both bow nuts, when
screwed up against the packing making a perfect water tight joint all round.
The said lights can be made with swing dead doors, or detachable. Where
detachable ones are required there will be a saving in cost. As one ship only
require a few to stand by in case of an accident.

We, Joux SHAW, 28, Rosehill Terrace, Willington-on-Tyue, in the County of
Northumberland, Ironfounder, and JoHN GRANTHAM, 54, Beaconsfield Street,
Blyth, in the County of Northumberland, Retired Plumber, 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:-
It consists of a flange ring A, inner ring B, glass frame C, outer case 1), screw
bolts E, bownuts l', screw ring G and dead light where required.
The object of our invention is to give free ventilation between decks, and a
more secure light in a rough seu.
The flange ring A is provided with a spigot to come through ship's shell, anl
is secured to same by flush rivets. The said flange is provided with bolt holes,
counter sunk on the side next to ship's shell, or slit holes to the outside of flange,
so that the screw bolts may be slipped in, for the purpose of fixing the outer
case 1), to flange ring A on the inside of ship, as shown by Figs. 5 and 6.
From the said bolt holes to the outside of the flange A, is slotted for the
purpose of sliding screw bolts into, from the outside of the flange into the said
bolt holes, after the flange ring A has been fixed to ship's shell. The object of
this arrangement, is that the flange ring A, may be fixed, in the first place by
its self the other parts of light can be fixed as required thereby preventing the
light being damaged, when fixed as a complete light.
The inner ring B, for carrying the glass frame C is provided with lugs for
fixing bownut screw bolts in, and holes for pivots to revolve in.
The outer case D is formed like the letter Z, forming a flange to fix to flange
ring A with holes for square taper headed bolts, or slits as shown in Figs. 5
and 6, also a recess for an india rubber ring for making a water tight joint.
The said casing is also provided with lugs forming a hinge for screw down bolts,
and recesses to receive lugs of sliding ring B, as shown in Fig. 2 through A, B.
The ring C or glass frame is recessed on the inside to receive glass, which is
secured by the screw ring G. The ring C is attached to sliding ring B by means
of two pivots one at top and bottom. The inside edge of casing 1) is recessed
at K for C to fit against, and to allow glass frame C to revolve on its pivotes,
when pressed back, and for holding ring C at any angle by screwing up bow-
nuts as showing through A, B, Fig. 1.
This invention will be better understood if reference is made to the drawings
of which-
Fig. 1, is a front elevation of ship's side light.
Fig. 2, is a horizontal section of same through A, B.
Fig. 3, is a side view with glass open for ventilation.
Fig. 4, is a vertical section of same through C, D.
Figs. 5 and 6 are views of square taper headed screw bolts, and slits for same.
In carrying out this invention the flange ring A, is flush riveted to ship's
shell, with either projecting screw bolts, or slits in flanges for square taper
headed bolts to fit in for securing outer case D to flange ring A.
The glass frame C and inner ring B is placed inside of outer case D, with india
rubber ring H and then placed on projecting screw bolts in the flange ring A,
or by the square taper headed screw bolts put into slits and screwed up, with a
little cement between the two flanges, will make a perfect water tight joint, when
screwed tight up.
When fixed in position, the heavier the sea strikes the glass, the tighter it

page_text: makes the rubber joint allround, inside of outer case D, and does not depend on
the bownuts or hinge fastenings entirley, the said bownuts Falso holds the
glass light in position when close or open for ventilation.
When ventilation is required, the bownuts are screwed back, to allow C
and B to be pressed back, to allow C to revolve in B clear of D, when set at the
required angle for ventilation it is screwed up against K in outer case D and
held in position by bownuts F. When closing again the bownuts F, are screwed
back and C set in position it is then drawn back against the rubber seating H,
and made tight with bownuts F.
By this invention there will be no broken glasses, in riveting flange ring A to
ship's shell, as the other parts CB and D can be applied afterwards, by means
of the square taper headed screw bolts.
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:-
First. The inner ring B for carrying glass frame C.
Second. The outer case D) with seat for rubber ring H.
Third. The flange ring A with square taper holes or slits.
Fourth. A ship side or deckhouse light constructed substantially as described
with reference to drawings and operating as and for the purpose specified.
