Fig. 2 is a front view of the same;

My life raft release consists of brackets l at
tached to the side 2 of a ship 3 for supporting a
life raft 4. The raft is held by ropes 5 passing
through cleats 6 havingv concave sides for en
gaging the raft, the outer ends of the ropes being
fastened to the brackets l, the inner ends being
attached to a plate 1. The plate has a hole at
the end for engaging a hook 8 pivotally support
ed at 9 on a post H! which may be made of angle
iron supported on the deck ll of the ship, The
hook in its operative position, as shown in Fig. l
pulls on the ropes 5 thereby pressing the life raft
by the cleats to the side of the ship. The hook is
retained in this position by a lever l2 having a
hole for the hook 8. The lever is pivoted at l3
on the post It) and has a handle M for its manual
as shown in Fig. 4. ,The boat rests on block 26
on the deck I I and is held down by bars 21. One
end of each bar is fastened by ropes or lashes
28 to hooks 29 on the deck II. The other end
of the bar has an extension 30 with a pivot 3|
at the lower end for a hook 32. The latter is
held under tension ‘by ropes or lashes 33 fas
tened to a hook 34 on the deck II. The end of
the hook engages an arm 38 pivoted at 35 to the
end of, the bar 21 and having a handle 36_at the
middle and a ?oat '31 at the end. The hook 32
can be released manually by lifting the arm 38
by the handle 36 or it can be released automat
ically when the ?oat 31 is submerged in water.
It is understood that my life raft release may
be further modi?ed without departing from the
spirit of the invention, as set forth in the ap
pended claims.
I claim as my invention:
1. Life raft release comprising means to re
_ leasably support a life raft at the side of a ship; ,

position, the pin engaging a corresponding hole
