PROVISIONAL SPECIFICATION.
Improvements in Ships' Hatch Covers, Bulkheads, and the like.
We WALTER ERNEST HUTCHINSON, Mariner, of 61 Poets Road, Canonbury, N.,
and ARTHUR EDWARD NEWTON, Mariner, of 16 Linthorpe Road, Stamford
Hill N., do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide an efficient means for readily closing
ships hatches, bulkhead, and the like and consists in forming the said cover or
bulkhead of one or more series of laths or bars of any suitable cross section and
material, secured parallely, to bands, wire ropes or the like connecting pieces or
strips somewhat after the mauner of the ordinary and well known roller shutters.
The opening to be covered may be spanned by suitable guide and bearing joists
or bars and stanchions which serve to support the laths and, where the cover is
composed of several sections, to also form division beams for the said sections.
A hatch cover so constructed when not in use may be rolled into a compartment
on or under deck out of the way and may be actuated by means of a small winch
or other convenient means.
Similarly in the case of bulkheads the rolled laths may be stowed away at each
end of the bulkhead, the said laths standing vertically and sliding when in action
horizontally athwart ships or at any angle desired.

COMPLETE SPECIFICATION.
Improvements in Ships' Hatch Covers, Bulkheads, and the like.
We WALTER ERNEST HUTCHINSON, Mariner, of 61 Poets Road, Canonbury, N.,
and ARTHUR EDWARD NEWTON, Mariner, of 16 Lindthorpe Road, Stamford
Hill, N., 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 to provide an efficient means for readily closing
ships' hatches, making temporary bulkheads and the like and consists in forming
the said cover or bulkhead of one or more series of laths or bars of any suitable
cross section and material secured parallelly to bands, wire ropes or the like
connecting pieces or strips somewhat after the manner of the ordinary and well
known roller shutters.
In the accompanying four sheets of illustrative drawings:-
Fig. 1 is a plan of a hatch one half of which is provided with a cover constructed
according to this invention.
Fig. 2 is an elevation of a part of the same and Fig. 3 a perspective view of
laths tubes or the like joined together to form a hatch cover.
Fig. 4 is a perspective view of a hatch with cover between decks, and
Fig. 5 shows in perspective a bulkhead constructed according to this invention.
Referring to Figs. 1, 2, and 3 the hatch frame or casing a is divided by a central
longitudinal beam b. One half of the hatch so divided is shown as covered in the
ordinary manner by means of wooden covers c while the other half is shown as
D

page_text: provided with a cover constructed according to this invention which comprises a
series of tubes e connected together by means of wires or bands f. At one end of
the frame a is a roller g mounted in suitable brackets h and provided with a
handle by means of which it is rotated by hand so as to wind the cover on or off
to open or close the hatch as will be readily understood. Ventilation may be
obtained through the cover-by the insertion of washers strung on the wire and
between the laths e.
In the arrangement of hatch cover shown in Fig. 4 flat laths / are employed
jointed together and sliding on supporting joists m and crossbearers n and being
guided by angle plates o. The cover is wound upon a winch as in Figs. 1, 2, and 3
or upon a spring roller, as in ordinary roller shutters which roller may be fixed in
a suitable compartment above or below deck.
The bulkhead shown in Fig. 5 consists of laths p hinged or otherwise connected
together and sliding in suitable guides and being further supported by battens s.
When not in use the laths are rolled up and stowed away in compartments t at each
end of the bulkhead.
Having now particularly described and ascertained the nature of our said
invention and in what manner the saine is to be performed, we declare that what
we claim is :-
1. A hatch cover comprising tubes, lathe or the like sliding in guides in the hatch
frame, and connected together by means of wires or bands and connected to a hand
or spring roller substantially as described with reference to Figs. 1, 2 and 3 of the
drawings.
2. A hatch cover comprising laths tubes or the like hinged or otherwise connected
together and sliding in guides and on supporting joists connected to the hatch frame
and being capable of being wound on a roller above or below deck substantially as
described with reference to the drawings.
3. A bulkhead consisting of laths sliding in guides hinged or otherwise connected
together and capable of being wound on a roller at each end of the bulkhead
substantially as described with reference to Fig. 5 of the drawings.
