Improvements in Side Souttles for the Lighting and Ventilating
of Ships.
We, GEORGE THOMAS TEMPLE, Assistant Manager, HENRY BURNETT
WATSON, Engineer and JOHN STANLEY WATSON Engineer all of High Bridge
Works in the City and County of Newcastle-ou-Tyne, 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 side scuttles for the lighting and
ventilating of ships and consists partly in certain improvements in details connected
with Henry Burnett Watson and John Stanley Watson's Patent No. 22054 of the
year 1804 in which a sliding pivot device and screwed jointing frame are described
and otherwise as hereinafter set forth.
In our present improvements we provide in connection with the said screwed
jointing frame and sliding pivot means for automatically effecting the adjustment
of position of the pivot by the motion of the jointing frame these means being
likewise applicable to jointing frames other than screwed ones as hereinafter
described; we will fully describe these and other subsidiary or minor improve-
ments with reference to the accompanying drawings in which Figure 1 shows a part
sectional elevational view, Figure 2 being an explanatory plan view of part of same;
Figures 3 and 4 show similar views of a modified construction or arrangement of
jointing frame or method of working same; Figure 5 is a side sectional view of the
opening ring hereinafter alluded to; Figures 6 and 7 show details hereinafter
described; and in the following description like marks of reference designate like
parts.
Referring to the drawings, it will be observed that the pivot B upon or round
which the casement A is adapted to revolve is arranged so as to be capable of
sliding in a groove or slot D and that the screwed jointing frame is utilised for
tightening up the casement against a rubber or other jointing ring H or when
unscrewed for permitting the casement to be opened and held in any required
position as fully described in the former Patent No. 22,054.
In our present improvement within the flange F¹ or the equivalent thereof of the
jointing frame we place a ring F which may be held in position by screws S
(against which it can slide) and carries opposite each pivot bolts or bars 10 which
pass through a frame 12 enclosing the pivot and terminate in heads 13 adapted to
work in openings 14 of the frame 15.
Thus when the jointing frame F is unscrewed it draws with it the parts 10 until
the heads 13 thereon touch the frames 12 and draw forward the pivots and casement
synchronously with the unscrowing of the jointing frame.
In screwing up the frame F the parts can thus assume automatically the position
shown in the figures.
Instead of the screwed jointing frame wo sometimes employ a slotted frame such
asf (see Figures 3 and 4). In this arrangement the flange of the frame has say
three or four slots such as f¹ conveniently formned or disposed around its periphery.
Each slot preferentially works on a roller-clad pin p secured in the fixed frame.
The ends of the slots are designed to effect the locking of the frame against the
pins the middle part serving to effect the opening or closing.
Such a device is obviously capable of being used or applied in connection with
the patent hereinabove already alluded to or in connection with the automatio

page_text: pivot-adjusting mechanism above described or with reference to Figures 1 and 2 of
the drawings.
The bracket in which the opening ring R ou the scuttle or casement is mounted
is formed with a projecting flange R¹ which effectually prevents the ring getting
jambed when closing the parts.
In Figure 6 is shown a spring paul device which may be fitted to the jointing
frame; the point of the paul P being forced into a recess or interruption P¹ of the
screw on which the jointing frame works the ring is prevented from being entirely
screwed off its framo or flange; the paul has a slotted hole at its centering t
relieve the pin of strain and transfer it to the casing C; or the above result may
be obtained by providing a stop T on the frame (see Figure 7) adapted to conie
into contact with a stop T on the fixed frame at the required moment in its
revolution.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In side scuttles in which the pivots of the revoluble casements are capable of
a sliding motion in slots provided in the fixed frame the means for synchronously
with the unscrewing of the jointing frame automatically drawing forward the
pivots and casement substantially as and for the purposes herein set forth.
2. The arrangement or combination of parts substantially as herein described
and illustrated with reference to Figures 1 and 2 of the drawings.
3. The arrangement or combination of parts substantially as herein set forth
with reference to Figures 3 and 4 of the drawings.
4. In combination with casements adjustably pivoted and arranged to be
tightened up or unfastened or held in any desired position by jointing frames as
herein described opening rings R with flanges R substantially as and for the
purposes herein set forth.
5. In combination with casements adjustably pivoted and arranged to be
tightened up or unfastened or held in any desired position by jointing frames as
herein described the means for preventing the said jointing frames from becoming
entirely unscrewed substantially as herein set forth.
