Improvements in Covers for the Cross Hatches of Vessels.
I, HORACE SEE, of 1, Broadway, in the City and State of New York, United
States of America, 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:―
My invention relates to a cover used to close the cross hatches of vessels.
My invention consists in such a cover made in sections, the said sections being
arranged in pairs and connected together so that either member of a pair of
sectional covers may be folded back one upon the other and secured in folded
position. One member of each pair may also be hinged to the vessel, so that
after the folding is done, the pair of folded members may be turned sidewise
to completely expose the hatch opening. I may use any number of such pairs
of folding sectional covers.
In the accompanying drawings, Fig. 1 is a plan view, showing two sectional
covers and a part of a third in place upon the hatch. Fig. 2 is a plan view of
a part of the deck of a vessel showing two pairs of sectional covers in place
and closing the hatch. Fig. 3 is a sectional view on the line 3, 3 of Fig. 2.
Fig. 4 is a detail plan view showing more particularly the arrangement of the
fastening bolt for the sectional covers. Fig. 5 is an enlarged detail section on the
line 5, of Fig. 1. Fig. 6 is an enlarged detail section on the line 6, 6 of
Fig. 1 and Fig. 4.
Similar letters of reference indicate like parts.
Referring first to Fig. 2, A represents a portion of the deck of a vessel. The
cross hatch cover B as here shown is composed of two pairs of sectional covers,
C and D being one pair, and E and F another pair. The number of pairs of
sectional covers making up the complete cover is not material, and will depend
upon the width of the hatch, so that I may use two, three or more pairs, as
may be desirable. Each pair of covers as C and 1) are connected together by
hinges G and H, and, as shown in Fig. 2, each inboard section as D or E is
connected by hinges I, J or K, L to the vessel. It will be seen therefore that
I may fold the section C upon section D, and I may turn section D upon its
hinges I and J so as to expose so much of the hatch opening as is covered by
the section C and D; or if it be desired to expose only so much of the opening
of the hatch as is covered by the section C, then I have only to turn the section C
back upon the section D. Similarly with regard to the sections E and F. By
turning the section I back upon the section E and then turning the two sec-
tions upon the hinges K and L, I expose all that part of the hatch which is
covered by the section E and F. Consequently, I may open the hatch beneath
the section C or beneath the section F or beneath the sections C and D) or beneath
the sections E and F; or I may by throwing back all of these sections expose
the entire hatch opening. By taking out the hinge pins of the hinges I, J, K, L,
and thus detaching the sections D and E from the hatch, I may fold the sec-
tion E back upon the section F and the section D back upon the section C,
thus exposing the middle portion of the hatch opening which is covered by the
sections D and E.

page_text: Around the edges of each of, the sections are a number of fixed plates as M,
cach having an opening to receive a swinging bolt as N, which is pivoted in
lugs to the hatch coaming. The bolts N are provided with nuts P, by
which when they are inserted in the openings of the plates M, the sectional
covers C and D and E and F are firmly secured in place. In order to make the
joint perfectly tight, I provide on the under side of each of the sections a layer
of rubber as Q, Fig. 6, which is forced against the upper edge of the hatch
coaming when the nuts P are set up.
Pivoted in brackets R on the inboard sectional covers as D and E are swing-
ing bolts S. When the outboard covers C and F are folded back upon the
inboard covers D and E then the plates M³ of cover C, for example, come over
the brackets R of the cover D), for example, so that the bolt S may enter the
jaws of plate M and be set up by nuts as T. In this way the cover C after
being folded over is secured to the cover D, and similarly the cover F to the
cover E.
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. In a cross hatch cover for vessels, two sectional covers C and D, hinged
together so that either member of the pair can be turned or folded back upon
the other, substantialy as described.
2. In a cross hatch cover for vessels, two sectional covers C and D, hinged
together so that either member of the pair can be turned or folded back upon
the other and hinge connections between the edge of one member and the
vessel whereby said members when folded together can be turned in a direction
at right angles to the fold, to uncover the hatch opening, substantially as
described.
3. In a cross hatch cover for vessels, two sectional covers C and D) hinged
together so that each member of the pair can be turned or folded back upon the
other and means for detachably hinging one of said members to the vessel, sub-
stantially as described.
4. In a cross hatch cover for vessels, a plurality of pairs of sectional covers,
the members of each of said pairs being hinged together so that either member
of each pair can be turned or folded back upon the other member, substantially
as described.
