Improvements in Side Lights for Ships and the like.
I, ALBERT EDWARD SEATON of Wilton House, Holderness Road, Hull, in the
County of York, Civil and Mechanical Engineer and Naval Architect, do hereby
declare the nature of my said invention to be as follows:-
My invention relates more particularly to side lights for the ports in the sides
of a ship, cabin, or deck house, and the object of my invention is to improve the
means and appliances for securing the same when closed.
I am aware that there are devices in use having similar objects in view and also
that some of these devices provide for securing the glass frame when closed in
several parts of the rim simultaneously. The appliances for effecting this, have
however, been hitherto attached to the glass frame or moving part of the side
light rendering the same heavy, cumbersome and inconvenient.
By my invention I improve upon this arrangement by attaching such appliances
to the fixed part of the side light frame instead of to the moving part (that is to
say the opening and shutting part) as heretofore.
I effect this in the following manner :-
On the frame which is attached to the ships side, I form a fixed projecting rim
or ring which is provided with a flange or lip having in it suitable openings or
gaps so that I can pass into position on it, a loose locking or gripping ring which
is formed with two lips or flanges each containing openings or gaps, those on the
flange next the fixed frame breaking pitch with those on the flange next the glass
frame or joint side, it is also provided for a short distance on its outer circumference
with teeth forming a rack which is geared into a pinion so that the range through
which the gripping ring is turned is restricted by the length of the rack and
likewise by the teeth terminating in a solid part of the ring so that when the
gripping ring has been entered through the gaps on the fixed rim of the frame and
turned into its normal position when at work, it cannot again be got out so long as
the pinion and rack remain in gear.
The frame carrying the glass of the side light is attached to the fixed frame by
a hinge in the usual way and the rim itself is provided with gaps corresponding in
size and pitch to those already mentioned on the joint side of the gripping ring,
thus when it is desired to close the light, the projections on the glass frame are
brought opposite the gaps in the gripping ring and on being pressed close upon the
india-rubber facing piece the gripping ring which has its projections made wedge
fashion, is then turned by means of the rack and pinion, so that the projections on
the glass frame are brought under the projections on the gripping ring, by which
means it is secured, tightened and locked, simultaneously, in as many positions as
there are gaps and projections provided for the purpose; in most cases the glass
frame would be thus secured in four places equidistant from each other.
As a modification of the arrangement of the wedge formation on the projections
of the gripping piece the projections on the glass frame may be formed wedge
fashion or the projections on the gripping ring and glass frame may both be
formed wedge fashion, or the flange projections on the fixed rim may have a
portion of each segment formed wedge fashion, and a corresponding projection on
the gripping ring likewise formed wedge fashion, so that the tightening up instead

page_text: of being effected by wedge action on the glass frame, will be by the wedge action
on the fixed portion of the frame.

Improvements in Side Lights for Ships and the like.
I, ALBERT EDWARD SEATON of Wilton House, Holderness Road, Hull, in the
County of York, Civil and Mechanical Engineer and Naval Architect, do hereby
declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
My invention relates more particularly to side lights for the ports in the sides of
a ship, cabin, or deck house, and the object of my invention is to improve the
means and appliances for securing the same when closed.
I am aware that there are devices in use having similar objects in view and also
that some of these devices provide for securing the glass frame when closed in
several parts of the rim simultaneously. The appliances for effecting this, have
however, been hitherto attached to the glass frame or moving part of the side
light rendering the same heavy, cumbersome and inconvenient.
By my invention I improve upon this arrangement by attaching such appliances
to the fixed part of the side light frame instead of to the moving part (that is to
say the opening and shutting part) as heretofore.
The nature of my invention will be better understood on reference to the
accompanying sheet of drawings in which,
Fig. 1, is a front elevation of my improved side light partly in section.
Fig. 2, is a sectional clevation of the same.
Fig. 3, is a section on the line A. B. shewing the glass frame closed and locked
by the gripping ring.
The same letters refer to similar parts throughout the several views.
I carry out my invention in the following manner :-
On the frame, a, which is attached to the ships side I form a fixed projecting
rim or ring, b, which is provided with a flange or lip, c, having in it suitable
openings or gaps d, d', so that I can pass into position on it a loose locking or
gripping ring, e, which is formed with two lips or flanges f, g, the lip or flange f
containing openings or gaps h, h', and the lip or flange, g, containing openings or
gaps, i,, those on the flange f, next the fixed frame, a, breaking pitch with those
on the flange, g, next the glass frame j, or joint side, it is also provided for a short
distance on its outer circumference with teeth k, forming a rack which is geared
into a pinion, l, so that the range through which the gripping ring e, is turned is
restricted by the length of the rack and likewise by the teeth terminating in a
solid part of the ring, e, so that when the lower projecting lips or flanges f, on the
gripping ring, e, have been entered through the gaps, d, d', on the fixed rim b, of
the frame, a, and turned into their normal position when at work, it cannot again
be got out so long as the pinion, 1, and rack, k, remain in gear.
The frame j, carrying the glass, m, of the side light is attached to the fixed
frame, a, by a hinge n, in the usual way and the rim itself is provided with
gaps o,.o', corresponding in size and pitch to those already mentioned (i, i,) on the
joint side of the gripping ring, e, thus when it is desired to close the light, the
projections p, on the glass frame j, are in position in the gaps, i, i', in the gripping
ring, e, as shewn in the drawing and on being pressed close upon the india-rubber
facing piece g, the gripping ring, e, which has its projections made wedge fashion is
then turned by means of the rack and pinion, so that the projections, p, on the glass

page_text: frame are brought under the projections, g, on the gripping ring, by which means it
is secured, tightened and locked simultaneously in as many positions as there are
gaps and projections provided for the purpose; in most cases the glass frame
would be thus secured in four places equidistant from each other.
As a modification of the arrangement of the wedge formation of the projections
of the gripping piece the projections on the glass frame may be formed wedge
fashion or the projections on the gripping ring and glass frame may both be
formed wedge fashion, or the flange projections on the fixed rim may have a
portion of each segment formed wedge fashion, and a corresponding projection on
the gripping ring likewise formed wedge fashion, so that the tightening up instead
of being effected by wedge action on the glass frame, will be by the wedge action
on the fixed portion of the frame.
As a further modification of the arrangement herein set forth, in order to prevent
the gripping ring, e, being moved out of fit with the glass frame j, when the latter
is open I provide a projecting nib, r, on the back of the hinge, n, of the glass
frame j, which is brought into a groove or slot, s, on the gripping ring, e, so that
when the glass frame is opened the gripping ing is locked and retained in the
proper position so that the gripping ring cannot be moved until the glass frame has
been completely closed.
When closed the projecting nib, r, comes clear of the slots, as shewn in Fig. 2,
and the gripping ring, e, can be turned by the rack and pinion into the necessary
position to secure the glass frame.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. In side lights for ships and the like the arrangement and combination of parts
and appliances for securing and locking the same when closed comprising a loose
locking or gripping ring fitting on to a fixed projecting rim or ring which is
attached to the ships side both being provided with lips or flanges having in them
suitable openings or gaps by means of which the glass frame which is also provided
with suitable openings or gaps may be secured, tightened and locked simultaneously
in several positions such loose locking or gripping ring being provided with a rack
actuated by a pinion by means of which it may be turned into the desired position
to close or open the glass frame, likewise providing the said locking or gripping
ring with projections forming a slot which receives when the glass frame is open a
projecting nib attached to the hinge of the glass frame and by means of which
when the glass frame is opened the gripping ring is retained in the proper position
to receive the glass frame when it is required to be closed, in the manner and for
the purposes substantially as herein described and illustrated.
