DIEUIFICATION.
Improved Method of Retaining in Position the Tarpaulins and other
Covers on Ships' Hatches, Skylights, Companions, and other Places
where it is Necessary to Batten Down.
I, JOHN MC'INTOSII, of Oakbank, Bowling, in the County of Dumbarton, North
Britain, Ships' Draughtsman, do hereby declare the nature of this invention to be
as follows:
This invention relates to an improved method of retaining in position the tarpau-
lins and other covers on ships' hatches, skylights, companions, and other places
where it is necessary to batten down.
In carrying out my invention I rivet or otherwise fix to the coaming of the hatch,
skylight, companion, or other place where it is necessary to batten down, a plate of
cast steel or other suitable metal, having two lugs cast or otherwise fixed thereto.
Pivoted to these lugs by means of a pin of brass or other suitable material, there is
a metal block having a striking head or top.
The tarpaulins or covers are placed over the hatch, skylight, companion, or other
place where it is necessary to batten down, in the ordinary manner, and the batten
placed against them. The block is then by a slight blow of a hammer pressed
down against the batten, when the tarpaulins or covers are held securely in position.
By striking the block on the opposite end it is easily released from its hold
thereby enabling the tarpaulins or covers to be removed.
Dated this 2nd day of June 1897.

Improved Method of Retaining in Position the Tarpaulins and other
Covers on Ships' Hatches, Skylights, Companions, and other Places
where it is Necessary to Batten Down.
I, JOHN MC'INTOSH, of Oakbank, Bowling, in the County of Dumbarton, North
Britain, Ships' Draughtsman, do hereby declare the nature of this said 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 an improved method of retaining in position the
tarpaulin and other covers on ships' hatches, skylights, companions, and any place
other than on board ship, where it is necessary to batten down hold fast or make
water tight.

page_text: In order that my invention may be properly understood and readily carried into
effect, I have hereunto appended one sheet of drawing illustrating the same as
applied in two forms on board ship.
Figure 1.is a sectional elevation of part of a ships hatch shewing my improve-
ments in a locked position.
Figure 2 is a similar view in the act of being brought into operation.
Figure 3 is an end view of the cleat or hold-fast.
Figure 4 is a similar view to Figure 1 of a modified form.
Figure 5 is an end view of the same.
Figure 6 is a part plan and part horizontal section of Figures 4 and 5.
In carrying out my invention, I rivet or otherwise fix to the coaming G of the
batch, skylight, companion, or any place other than on board ship where it is
necessary to batten down, hold fast or make water-tight, a plate B of cast steel or
⚫other suitable metal, having one or more jaws or lugs C, D, cast or otherwise fixed
. thereto.
Pivoted to these jaws or lugs C, D, by means of a pin E of brass or other
suitable metal, there is a metal block E having a striking head or top.
The tarpaulin or covers H are placed over the hatch, skylight, companion or any
place other than on board ship where it is necessary, to batten down, hold fast, or
make water-tight, in the usual manner, and the batten F placed against them.
The block E is then by a slight blow of the hammer pressed down against the
batten F, when the tarpaulin or covers H are held securely in position as shewn
.more particularly in Figure 1. By striking the block E on the opposite end it is
.easily released from its hold thereby enabling the tarpaulin or covers to be removed.
The metal block E may conveniently be made with duplex cam or locking
surfaces as shewn in dot and pick lines Figures 1 and 2. In such case it is or may
be provided with holes or slots to enable it to be locked and unlocked by a key or
bar.
Referring to Figures 4, 5, and 6, the bracket or plate B¹ is formed with a central
pin E which may be or form part of the bracket, or may be fitted separately in
it. The plate or bracket B₁ is strengthened by a central web. The metal piece E
is similar in construction to that already described as having a duplex cam or
locking surface, but instead of working in the vertical plane the locking and unlock-
ing is effected in the horizontal plane.
"
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I claim
is:
Retaining in position the tarpaulin and other covers on ships' hatches, skylights,
companions, and any place other than on board ship where it is necessary to batten
down, hold fast, or make water-tight, substantially in the manner and by the
apparatus hereinbefore described and illustrated on the accompanying sheet of
drawings.
