DESCRIPTION OF DRAWINGS.
Figure 1. is an inside sectional elevation of a portion of a hatch "Coaming"
with corners made according to my invention.
Figure 2. is an outside elevation of the same.
Figure 3 is a sectional plan on a 6 of Figure 1.
A is the corner portion of coaming ordinarily made of plate. B the straps, C the
beading, D the "kep" or ledge for hatch covers to rest upon the angle piece to
connect to deck all or any two or more parts of those according to my invention
made in one casting forming a rounded corner and joining by rivetting or bolting
to the straight sides and ends of the coaming F F¹ which are constructed in the
ordinary manner. Figures 4 and 5 shew two different sections of "beading" and
kep" ledge which are commonly used, forming part of the casting of corner of
coaming made according to my invention but of course any form of beading and
kep "ledge can be adopted to suit the sections of iron used in ends and order of
coaming. The "kep" or ledge D will not continue round the corner but follow
the dotted line in the casting as it is not required on ends of hatch.

Square corners can be made according to my invention but it is to rounded
corners (which are now the rule) that it is specially adapted.
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:
The construction of hatch "Coaming" corners comprising the "Coaming," straps
beading "kep" piece and angle piece, or any two or more such parts, in one casting
of steel cast mallable iron or similar metal substantially as shewn and described.
