Improvements in or relating to Ships' Side Scuttles.
I, WILLIAM MULLAN of Marlborough Park, Belfast in the County of Antrim,
Ireland, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the improved construction of ships' side scuttles
with a view of their being watertight when closed, and capable of being opened to
a greater or less extent, and of being retained in position when set to give the
desired amount of opening and generally to make them more couvenient than at
present.
In carrying out my invention, the scuttle frame is made with a groove all round;
in this groove a strip of india rubber or other suitable packing is fixed, forming the
seat upon which the frame of the window is pressed to make the joint water-tight.
The window frame can be arranged to slide, to roll or to swing on a pivot when
loosened from its seat. When it is made to roll or slide, the scuttle frame is
provided with two guides fixed upon it, or cast in one with it. These guides
project from the frame in a plane parallel to the plane of the glass, and are also
generally parallel to each other and placed at such a distance apart that the window
frame can roll or slide between them. The face of each guide is formed as a rail,
groove, tram or channel, upon which the window frame rolls or slides, and one or
both rails are made adjustable and fitted with one or more bolts, screws or their
equivalents, by which they can be moved or adjusted so as to nip the window
frame between them or against the scuttle frame and thus secure it in the desired
position. When the scuttle is closed, the window frame is pressed against the
rubber or other packing and secured watertight by two or more bolts fixed in the
scuttle frame or guides, each of these bolts having a nut and a block with a flange
free to travel on it. When the nuts are screwed up, the flanges on these blocks
bear on the window frame and thus press it against the rubber or other packing.
Handle latches with wedge-action-bearing-faces inay, in some cases, be used
instead of the bolts and nuts aforesaid. In some cases, I may join both guides
together or the rails or faces of these guides so as to form a rectangular frame or
an oblong frame with rounded ends and fit the latter with two or more securing
bolts which pass through it and thus do away with the flange blocks already
described. This plan is useful with square or rectangular scuttles, or in circular
ones of large size. If it be desired that the window frames instead of rolling or
sliding shall be pivoted, in place of using the guides, I hinge the window frame to
the scuttle frame pivoted preferably at the top. The scuttle frame is supplied with
a series of holes into which pegs can be placed, and also one fixed pin at the bottom
or point opposite the pivot. A hook on the window frame engages with any of
these pegs, and I prefer to place on the scuttle frame a stop to catch the window
frame should it be allowed to swing and thus take the strain off the stationary pin.
The stationary pin and the pivot can each be formed as a stud in the scuttle frame
and be supplied with a wing nut with a flange face; a toe on the window frame
projects over the flange. By this means, the window must be forcibly withdrawn
from the rubber joint before it can be taken off or swung to one side. The window
frame can be counterbalanced in any convenient manner, thus it can be raised by a
cord and pulley with a weight attached thereto. It can have a counterbalancing
weight on the opposite side of the pivot. The two scuttles can be formed joining
each other with the pivot between them and the two window frames be rigidly
attached together and thus counterbalance each other, one rising as the other falls,
or in place of the above mentioned counter-weight, a light cast brass or other metal

page_text: jalousie can be fixed to the window frame on the opposite side of the pivot, and
thus, by turning the window to an angle of 90 degrees, the scuttle is entirely open;
by turning to 180 degrees it is closed by the jalousie, and by turning it back again
or turning the entire circle, the window is again closed by the glass. As, however,
the arrangement of catch would have to be altered in case it was allowed to turn
through the entire circle, I prefer to so arrange it that it can only turn through
180 degrees and the window has to be turned back each time to close. With these
counterbalanced windows, they can be fixed rigidly in any given position, either by
clamping them with the nut on the pivot, or preferably by using pegs fixed into
holes in a semi-circular plate surrounding the main frame.

COMPLETE SPECIFICATION.
Improvements in or relating to Ships' Side Scuttles.
I, WILLIAM MULLAN of Marlborough Park, Belfast, County Antrim, Ireland,
Engineer 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 the improved construction of ships' side scuttles
which while watertight when closed shall be capable of being opened to a greater
or less extent by a sliding rolling or swinging action and of being retained in
position when set to give the desired amount of opening but always in a plane
parallel to the deckhouse or other wall to which they are applied so as not to
protrude more when open than when closed.
In carrying out my invention the scuttle frame is made as usual with a groove
all round in which a strip of india rubber or other suitable packing is fixed forming
the seat upon which the window is pressed to make the joint watertight.
When it is made to roll or slide the scuttle frame is provided with two guides
it or cast in one with it.
fixed upon
Figure 1 of the accompanying drawings is a face view of such a side scuttle
suitable for being applied to the inside of a ship's deckhouse or other structure and
Figure 2 is a vertical section. Figure 3 is a section on E F Figure 1.
The guides a project from the frame b in a plane parallel to the plane of the
glass c and are also generally parallel to each other and placed at such a distance
apart that the window can roll or slide between them. The face of each guide is
formed as a rail (or groove, tram or channel) upon which the window rolls or
slides and one or both rails are made adjustable and fitted with one or more bolts,
screws or their equivalents by which they can be moved or adjusted so as to uip the
window between them or against the scuttle frame and thus secure it in the desired
position. In the form here shewn the guides a are made in one piece which is fixed
to the wall e by two screws f and to the scuttle foundation frame 6 by two screws g
with hinged (or fixed) handles gl. By turning the screws g with their heads or
flanges against the guides a the window d can be tightened against the rubber ring h
for holding it tight in the closed position or released therefrom if the window is to
be slided into a partly or fully open position. The guide frame a a has to be sprung
slightly open for inserting the scuttle or window dc. ddare feet with screw
pegs d' the points of which enter small corresponding holes in the wall e for holding
the frame a a in place and in correct form to admit of the window sliding (or
rolling) easily therein.
Figure 4 shews a guide frame consisting of two guide bars a a of such a length
as to admit of the hole in the scuttle frame 6 being closed either by a glass
window c d or by a jalousie window o* d* or a dead door. The crutch handle

page_text: screws g g serve to make the window tight against the rubber ring on the frame b.
The crossbar with brackets or feet serves to secure the guide bars a a to the
wall and to hold them the right distance apart while admitting of slight adjustment
by means of the screws ².
In Figures 5 and 6 is shewn a guide frame consisting of two bars a a fixed at one
end to the scuttle frame b by means of the screws a¹ and assembled at the other
end by the bracket bar jjj and screws. The lower guide bar a is formed with
recesses a* and the outside of the window d with corresponding projecting pegs or
teeth d* which gear therewith when the window is rolled along between the guide
bars a.
Figures 7, 8, 9 and 10 shew another such form where the guide bars are united
at one end like in Figure 1 but that end held to the scuttle frame b by means of
the screw a¹ and two of the jambing screws g g' while at the other end the bars a
are united by the bracket bar j,,. The window d is on one side formed with
teeth and the lower guide bar a with teeth a gearing therewith and a gap a
for the lug of the left hand jambing screw to drop into when the window is rolled
into that position.
Figures 11 and 12 shew a jambing screw g with hinged head g¹.
Figures 13 and 14 shew an oval window adapted to work between guide bars a
fixed at one end to the scuttle frame and at the other end to the wall by means of
the bracket bar j, j, j'. The window is provided with rollers d³ ³ which work on
the lower guide bar a.
Figures 15 and 16 shew a similar arrangement adapted to a rectangular window.
Figure 17 shews a guide frame with vertically sliding window which is counter-
balanced. The fittings for fixing the guide frame and for jambing the window may
be as in the previous examples.
Handle latches with wedge action bearing faces may in some cases be used instead
of the bolts 9.
The
If it be desired that the window frames instead of rolling or sliding, shall be
pivotted, in place of using the guides, I hinge the window frame to the scuttle
frame pivotted preferably at the top. The scuttle frame is supplied with a series
of holes into which pegs can be placed and also one fixed pin at the bottom or point
opposite the pivot. A hook on the window frame engages with any of these pegs
and I prefer to place on the scuttle frame a stop to catch the window frame should
it be allowed to swing and thus take the strain off the stationary pin.
stationary pin and the pivot can each be formed as a stud in the scuttle frame and
be supplied with a wing nut with a flange face; a toe on the window frame projects
over the flange. By this means the window must be forcibly withdrawn from the
rubber joint before it can be taken off or swung to one side. The window frame
can be counterbalanced in any convenient manner, thus it can be raised by a cord
and pulley with a weight attached thereto.
Figure 18 shews such an arrangement the window d pivotting on the bolt k and
counterbalanced by the weight 1.
Figure 19 shews a counterbalancing weight on the opposite side of the pivot.
Figure 20 shews two scuttles d d combined with the pivot k between them, and
the two window frames thus counterbalance each other one rising as the other falls.
Figure 21 shews a light cast brass or other metal jalousie d* combined with the
ordinary window d on the opposite side of the pivot k, and thus by turning the
window to an angle of 90 degrees, the scuttle is entirely open; by turning to
180 degrees it is closed by the jalousie, and by turning it back again or turning
the entire circle, the window is again closed by the glass. As however the arrange-
ment of catch would have to be altered in case it was allowed to turn through the
entire circle, I prefer to so arrange it that it can only turn through 180 degrees
and the window has to be turned back each time to close. These counterbalanced
windows can be fixed rigidly in any given position either by clamping them with
the nut on the pivot or preferably by using pegs fixed into holes in a semi-circular
plate surrounding the main frame.

page_text: 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. Side scuttles constructed substantially as described with reference to the
drawings and arranged to work in a plane parallel to the wall or plating and capable
of being opened to a greater or less extent by a sliding or rolling motion.
2. Counterbalanced side scuttles constructed substantially as described with
reference to the drawings and arranged to work in a plane parallel to the wall or
plating and capable of being opened to a greater or less extent by a swinging
motion.
