PROVISIONAL SPECIFICATION.
Improvements in Hatchway Coverings or Hatches.
I, JEREMY COLLIER ST. AUBYN ANGOVE of 14, Great Winchester Street, in
the City of London, Gentleman, do hereby declare the nature of this invention
(a communication to me by Edward Trelawny, of The Peninsular and Oriental
Steam Navigation Company's Offices, Calcutta, East Indies, Superintendent) to be
as follows:
My invention relates to an improved hatch or covering for the hatchways of
vessels, consisting of hinged gratings provided with means for enabling them to
be readily raised and lowered, so as to open or close the hatchway, and which,
when raised, constitute guards or screens for the openings. Each of these gratings
is independently hinged to the coamings at one of its edges, the gratings meeting
when lowered and being supported on a cross-beam. The gratings may be raised
and lowered conjointly or independently, by tackle carried by an overhead
support, and the gratings may be counterweighted to enable them to be operated
more easily.
Dated this 24th day of January 1894.

COMPLETE SPECIFICATION.
Improvements in Hatchway Coverings or Hatches.
I, JEREMY COLLIER ST. AUBYN ANGOVE, of 14, Great Winchester Street, in
the City of London, Gentleman, do hereby declare the nature of this invention
(a communication to me by Edward Trelawny, of The Peninsular and Oriental
Steam Navigation Company's Offices, Calcutta, East Indies, Superintendent), 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 to grated coverings for the hatchways of vessels and
consists in hinging the gratings to the coamings of the hatchway and providing
means whereby the gratings may be readily raised to give passage through the
hatchway and held in the raised position so as to form a fence for the hatchway.
The invention is illustrated in the accompanying drawings, forming part of
this Specification, wherein Figure 1 is a cross-section through the hatchway
shewing one half the batchway closed and the other partly open, and Figure 2 is
a plan of the same.
A, A, are iron gratings hinged at a to the coamings at the opposite sides of
the hatchway, the gratings being of such dimensions as to cover half the breadth
of the hatchway and rest on a central longitudinal bar C whose ends are supported
in sockets D fixed to the head ledges so that the bar may be removed when
required. The gratings may extend the full length of the hatchway in one length,
or they may be divided into two or more sections adapted to be independently raised
and lowered as shewn. For the purpose of raising and lowering the gratings there
is attached to each grating a whip-tackle formed by a rope E passing over a pulley F
supported by the deck above or other overhead support, suitable cleats or other

page_text: means of making fast the fall being provided. Or a double or multiple purchase
tackle may be used if required. By this means the gratings may be raised and
held in a vertical position, as shewn in dotted lines in Figure 1, in order to give
access through the hatchway and in this position they serve to fence the sides of
the aperture and prevent any person accidentally falling through.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I,declare that what
I claim is:-
The herein described hatchway, gratings hinged at opposite sides to the coamings
and adapted to rest on a removable supporting bar at the middle, and, to be raised
to and held in an upright position by means of, tackle, substantially as and for the
purpose specified.
