PROVISIONAL 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 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.
In carrying out my Invention I employ a main frame which may be of steel or
iron or other suitable metal and which is fixed to the ships' side. On the main
frame I fix an inner frame by preference of brass or gun metal having a bearing
surface for the glazed frame which closes the aperture when light only is to he
admitted. The glazed frame is hinged to a plate or block which is fitted to slide on
guides in the main frame or is arranged to move on a fixed pin; and when the
glazed frame is to be closed its hinge plate or block is moved in the guides on the
main frame so as to cause a flange on the glazed frame to become locked in one or
more claw-like projections on the main frame, the flange and the locking projections
being arranged to act like wedges to force the glazed frame closely in contact with
the inner frame. For moving the glazed frame in the manner described there is
fitted in connection with its hinge plate or block a small eccentric or cam or equivalent
device which can be turned by means of a handle or key. A metal cover may be
provided when required for entirely closing the scuttle and excluding light and is
hinged to the main frame. The cover is arranged to fit closely upon the outer part
of the glazed ring. The fitting surfaces between the main frame and glazed frame
and between the glazed frame and cover may be made to fit closely, metal to metal,
or one of each of the pairs of surfaces may be formed with a groove having on it a
ring of suitable compressible material.

COMPLETE SPECIFICATION.
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 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 in order that my said Invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings to be
hereinafter referred to, and showing my improved ships' side scuttle.
Figure, 1, on the accompanying sheet of explanatory drawings is a plan of the side
scuttle figure, 2, being a front elevation with separate sections of two parts below it,
and figure, 3, is a transverse vertical section of the same. Figures, 4, 5, and 6, are
views of details. 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 I employ a main frame which may be of steel or
iron or other suitable metal and which is fixed to the ship's side. On the main
frame I fix an inner frame, by preference of brass or gun metal, or instead of two
frames there may be one main frame, 7, as shown in the drawings. This frame, 7,
has a ring of rubber, 8, or other suitable compressible material laid in a groove in

page_text: the
its inner surface to form a bearing surface for a glazed frame, 9, which closes the
aperture when light only is to be admitted. The glazed frame, 9, is connected by a
pair of hinges, 10, to a plate or block, 11, shown separately in figures, 4, and 5,
which are respectively a front elevation' and 'a horizontal section; and which is fitted
to slide in guides, 12, formed on the uppers part of the frame 7 (or the plate, 11, 5
may be arranged to move on a fixed pin). When the glazed frame, 9, is to be
closed its hinge plate or block, 11, is moved in the guides,-12,.
-on-the. frame, 7,
so as to cause a flange, 13,.. on the glazed frame, 9, to become locked in two claw-
like projections, 14, (shown separately below figure, 2) formed on the frame, 7,
flange, 13, and the locking projections, 14, being arranged to act like wedges to 1
force the glazed frame, 9, closely in contact with the bearing surface, 8. on the
frame, 7. To open the glazed frame, 9, its' binge plate or block, 11, is moved in
the opposite direction so as to release the flange, 13, from 'the projections, 14, a
catch, 15, being provided at the lower side of the glazed frame, 9, to take hold of
in opening it and also to retain it in its open position by being engaged with a 1
chain ring or other suitable device when open. For moving the glazed frame, 9,
in the manner described there is fitted in connection with its hinge plate or block, 11,
a small eccentric or cam, 16, (or equivalent device) formed on the end of a stud,. 17,
working in a socket in the frame, 7, and which can be turned by means of a
handle or key, (figure' 6) inserted in a hole in the stud, 17, so as to cause the
cam, 16, to turn in a recess, 18, in the hinge plate or block, 11; when the glazed
frame, 9, is to be opened or closed. A small piece on the cam, 16, projects over
the flange, 13, to assist in retaining the glazed frame, "9, in its closed position in
addition to the projections, 14; herein before described.
•
A metal dark cover, 19, (shown only in figure, 3) is provided to be used when
required for entirely closing the scuttle and excluding light. 'This cover, 19, fits
closely upon a bearing' surface, 20, of rubber, or other suitable compressiblo material
laid in a groove in the surface of the glazed frame, 9, and it is held in its place by
causing its flange, 21, to lock in two claw-like projections 22, one of which as shown
separately below figure, 2, is formed on the frame, 7, the other being formed on the
glazed frame, 9. The cover is locked in its closed position by means of a small
eccentric or cam, 23, formed on a stud, 24, working in a socket in the frame, 7, and
which can be turned by means of the key, (figure 6) when inserted in a hole in the
stud, 24,180. as to cause the cam, 23, to bear on the flange, 21, and make it engage
with the projections, 22, a small piece, 25, on the cam, 23, projecting over the
flange, 21, and assisting the projections 22, in retaining the cover, 19, in position.
The cover, 19, is provided with a handle, 26, to take hold of in removing it from the
projections when the cam, 23, is turned back.
The rubber rings, 8, and 20, may be dispensed with and the bearing surfaces
and
..between the frame, 7, and glazed frame,: 9, and between. tho:.glazed frame, 9,
cover, 19, may be made to fit closely, metal to metal.
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 1
claim. is:
1. The combination or arrangement of parts forming my improved ship's side
scuttle substantially as herein before described and shown on the accompanying
'drawings.
"2. 'In a ship's side scuttle hinging the glazed' frame' to a plate or block movable in
guides substantially as herein before described.
3. In connection with a ship's-side scuttle providing a separate 'dark cover and
holding and locking devices for the same substantially such as are hereinbetore
described.
