I, WALTER SCOTT WINANS of No. 12 Beaufort Gardens Brompton Road London
Civil Engineer do hereby declare the nature of this invention to be as follows :—
This invention has for its object improvements relating to the bulkhead doors of
ships and vessels.
I adopt the following construction; the door frame is formed of oblique angle
iron welded up into a rectangular frame but with the corners somewhat rounded.
This frame is securely rivetted to the skin plates of the bulk head. The door plate is
of sheet iron suitably strengthened and it is hinged to the frame on one side. The
door plate is of larger size than the opening through the bulk head as it loosely fits
the outer side of the door frame which in consequence of the oblique form of the
angle iron is considerably larger than the opening on the inner side where the frame
is attached to the plates of the bulk bead. On the inner side of the door plate all
around and at a short distance from the edge a lip is attached and over this lip a ring of
india rubber made somewhat similar to the tyre of a bicycle wheel is sprung.
On the side of the door frame opposite to that at which the hinges are fixed eyes
are provided to which stems with screw threads upon them are jointed and these
screw stems receive nuts. The nuts when screwed up bear against the outer face
of the door plate and press it forciby into the tapering recess presented by the
door frame. The india rubber packing ring takes a bearing against the oblique
sides of the door frame all around and the pressure inwards of the nuts ensures a perfect
joint. There are studs on the edge of the door plate where the nuts bear upon it
and these studs enter grooves on the inner sides of the nuts. The studs serve to confine
the nuts in place on the door plate when screwed up but when the nuts are
slackened the stems can be turned about the joints which attach them to the door
frame and the nuts can thus rapidly be moved out of the way to permit the door
to open.
Bulk head doors are thus readily fitted watertight without any great accuracy of
workmanship being necessary-the construction is consequently inexpensive. The
doors also may be so fitted as not to interfere materially with the level of the floor
line at the doorway.

Civil 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 improvements relating to the bulkhead doors of
ships and vessels.
adopt the following construction; the door frame is formed of oblique angle iron
welded up into a rectangular frame but with the corners somewhat rounded. This
frame is securely rivitted to the skin plates of the bulk-head. The door plate
is of sheet iron suitably strengthened and it is hinged to the frame on one side.
The door plate is of larger size than the opening through the bulk-head as it loosely
fits the outer side of the door frame which in consequence of the oblique form of
the angle iron is considerably larger than the opening on the inner side where the
frame is attached to the plates of the bulk head. On the inner side of the door
plate all around and at a short distance from the edge a lip is attached and over
this lip a ring of India rubber made somewhat similar to the tyre of a bicycle wheel
is sprung.
On the side of the door frame opposite to that at which the hinges are fixed eyes
are provided to which stems with screw threads upon them are jointed and these
screw stems receive nuts. The nuts when screwed up bear against the outer face of
the door plate and press it forcibly into the tapering recess presented by the door
frame. The india rubber packing ring takes a bearing against the oblique sides of
the door frame all around and the pressure inwards of the nuts ensures a perfect
joint. There are studs on the edge of the door plate where the nuts bear upon it
and these studs enter grooves on the inner sides of the nuts. The studs serve to
confine the nuts in place on the door plate when screwed up but when the nuts are
slackened the stems can be turned about the joints which attach them to the door
frame and the nuts can thus rapidly be moved out of the way to permit the door to
open.
Bulk head doors are thus readily fitted watertight without any great accuracy of
workmanship being necessary-the construction is consequently inexpensive-The
doors also may be so fitted as not to interfere materially with the level of the floor
line at the doorway.
The drawing annexed shews a bulk head door and door frame formed as above
described.
Figure 1 is a face view of the door and frame.
Figure 2 a face view of part of the same on a larger scale.
Figure 3 is a horizontal section.
A is the door frame of oblique angle iron.
B the skin plates of a bulk-head to which the angle iron frame is rivitted C. is the

page_text: door hinged to the frame by hinges D. E. is the soft packing around the edge of
the door and held between the inner side of the door plate and a lip F rivetted to
it as shewn in Figure 3 G. G. are screw stems jointed to the door frame on the
side opposite to that to which the door is hinged H. H. are nuts screwing on to
these screws-all around the face of each nut is a groove H¹ as shewn on Fig. 3.
1. I. are small studs on the door to enter these grooves when the nuts are
screwed up.
Other ways of retaining the door when closed might be adopted-the way shewn
is however convenient for the purpose.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1. The combination of the door frame of oblique angle iron the door of larger size
than the opening hinged to it and the elastic packing placed all around the edge of
the door on the inner side to bear against the oblique face of the angle iron frame and
make a tight joint when the door is closed.
2. The means for locking the bulk-head doors substantially as described consisting
of the small studs on the door and the nuts grooved on their face and screwing on to
screw bolts jointed to the door frame.
