Improvements in Ships' Side Scuttles.
I, JAMES BROADFOOT, of 55 Finnieston Street, Glasgow, in the County of Lanark,
North Britain, Engineer, do hereby declare the nature of this invention to be as
follows, that is to say :-
My said invention has for its object to improve the construction of ships' side
scuttles with the view of having them watertight and secure when closed and capable
of being set open to a greater or less extent.
In carrying out my invention the scuttle frame is made with a concavely conical
inner edge or seat to receive the scuttle ring in which the glass pane is fixed. The
scuttle ring is made convexly conical to fit the seat, and a packing strip of leather or
other suitable material is fixed in a groove in one of the conical surfaces to form a
tight joint. The scuttle ring is made with a trunnion or stud projecting from it at
one end and in the line of a diameter; and on this trunnion there is fitted so as to
turn on it a block formed with trunnions or studs at its sides and at right angles to
the trunnion on which the block is fitted. The fixed scuttle frame is provided with
bearings for the trunnions of the block these bearings being in lugs between which
the block and the trunnion on which it is fitted are situated. The scuttle ring can be
swung on the block trunnions as on a hinge into a more or less open position and
when open it can be made to swivel on the trunnion in the block. At a point
diametrically opposite to its hinge trunnion the scuttle ring is provided with a stud
which works in a slotted bracket and which has on it a pinching screw nut for
securing the scuttle frame in a more or less open position. Handled latches or
fasteners with wedge-action bearing faces are provided for tightly securing the scuttle
ring in a closed position when required.

COMPLETE SPECIFICATION.
Improvements in Ships' Side Souttles.
I, JAMES BROADFOOT, of 55 Finnieston Street, Glasgow, in the County of Lanark,
North Britain, 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, that is to say :-
My said invention has for its object to improve the construction of ships' side
scuttles with the view of having them watertight and secure when closed and capable
of being set open to a greater or less extent.
And in order that my said invention and the manner in which the same is to be
performed may be properly understood I hereunto append a sheet of explanatory
drawings to be hereinafter referred to and showing my improved side scuttle.
Figure, 1, on the accompanying sheet of drawings is a plan of the side scuttle ;
Figure, 2, being an inside elevation.
Figure, 3, is a sectional view showing the scuttle in its open position and
Figure, 4, is a transverse vertical section of the scuttle without its frame.
In these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.
In carrying out my invention the scuttle frame, 5, is made with a conical inner
flange or seat to receive the scuttle ring, 6, in which the glass pane, 7, is fixed, the
said sheet being shaped so as to nearly fit the contour of the scuttle, 6, when the latter

page_text: is in the position in which it is shown in Figure, 3. The scuttle ring, 6, is made
convexly conical to fit the seat in the frame, 5, and a packing strip of leather or other
suitable material, 8, (Figure 4) is fixed in a groove in the conical surface of the scuttle
ring, 6, to form a tight joint. Or the packing material may be fixed in a groove in
the seat in the frame, 5, if preferred. The scuttle ring, 6, is made with a trunnion or
stud, 9, projecting from it at one end and in the line of a diameter, and on this
trunnion, 9, there is fitted so as to turn on it a block, 10, formed with trunnions or
studs, 11, at its sides and at right angles to the trunnion, 9, on which the block, 10,
is fitted. The fixed scuttle frame, 5, is provided with bearings, 12, for the trunnions, 11,
of the block, 10, these bearings, 12, being formed in lugs, 13, between which the
block, 10, and the trunnion, 9, on which it is fitted are situated. The scuttlo ring, 6,
can be swung on the block trunnions, 11, as on a hinge into a more or less open
position and when open it can be made to swivel on its trunnion, 9, in the block, 10,
(as shown in Figure, 3). Or the scuttle ring, 6, can be turned completely round and
then be adjusted more or less close to the frame, 5, when there will be an annular
space round it for the passage of air. At a point diametrically opposite to its hinge
trunnion, 9, the scuttle ring, 6, has formed on or fixed to it a stud, 15, which engages
in a slotted bracket, 16. on the frame, 5, and which has on it a pinching screw nut, 17,
for securing the scuttle ring, 6, in a more or less open position. Handled latches or
fasteners, 18, with wedge-action bearing faces are provided for tightly securing the
scuttle ring, 6, in a closed position when required, the fastenors, 18, acting on wodge-
shaped surfaces, 19, on the scuttle ring, 6. Any other convenient fasteners may be
used if preferred.
Having now particularly described and ascertained the nature of my said
invention and in what mannor the same is to be performed, I declare that what I
claim is :-
1. The combination or arrangement of parts constituting my improved ship's side
scuttle substantially as hereinbefore described and shown on the accompanying
drawings.
2. In a ship's side scuttle making the scuttle ring with a trunnion turning in a
block formed with trunnions at right angles and working in bearings on the scuttle
frame substantially as and for the purposes horeinbefore described.
3. The improved conical seat in the scuttle frame, 5, combined with the conical
surface of the scuttle ring, 6, substantially as herein before described.
