Improved Releasing-gear for Boats Carried on Board Ship, and for
Detaching the Covers of such Boats.
We, ROBERT JAMES GANT. of Wiveton, in the County of Norfolk, Mariner, and
GEORGE LARKMAN Mor, of 82, Stirling Street, Newelee, Grimsby, in the County of
Lincoln, Master Mariner, do hereby declare the nature of this invention to be as
follows:-
This invention consists in improved means for releasing boats carried on board ship
and for detaching the canvas covers usually placed over the open part of such boats.
According to this invention, boats carried on board ship are secured by means of
chains which at one end are secured to the ship's deck or linked to eyes therein.
At the other end each chain is provided with a ring or eye. Two or more of these
chains are situated at each side of the boat at opposite points. To secure the boat on
the deck each chain is carried up over the gunwale, and through the ring at the inner
end is then passed an arm binged in a jaw fixed at each end of the boats' seats.
Extending longitudinally along the centre of the boat is a main rope or chain
having branches to the free end of each of which is attached a pin or bolt which,
when the rings aforesaid have been engaged by the hinged arms or rods, is passed
across each of the latter through holes in the jaw.
Accordingly, the pins or bolts prevent the hinged arms from rising to free the chains
to which the rings are attached.
The pins or bolts are inserted in the jaws in an uniforın direction, and hence, if a
strain in the contrary direction be exerted on the central rope or chain, all the bolts
are simultaneously withdrawn from above the hinged arms aforesaid.
The holding chains thus set free fall out of the jaws on to the ship's deck and the
boat is released.
The usual canvas cover of a ship's boat is, according to this invention, provided at
both ends, at opposite sides, with a link of rope or short chain terminating in a ring
or eye. In the stem of the boat is an aperture sufficiently wide to receive the rings
of the front ropes or chains of the cover when the said rings are overlapped.
The rings of the stern ropes or chains are overlapped in a similar aperture in the
stern post. A pin or bolt attached to the longitudinal rope or chain aforesaid is
inserted in holes in the stem above the water line and, extending through the over-
lapped rings, holds the cover at the bow of the boat. In like manner, the cover is
secured at the stern. It is further secured by the chains which secure the boat on
the deck, the said chains being passed through apertures provided in the cover.
pins or bolts by which the cover is held at the bow and stern are inserted in the same
direction as those by which the chains holding the boat are entered. Consequently,
when the holding pins or bolts of the latter are withdrawn, as above described, the
cover is at the same time released.

Improved Releasing-gear for Boats Carried on Board Ship, and for
Detaching the Covers of such Boats.
ROBERT JAMES GANT, of Wiveton in the County of Norfolk, Mariner & GEORGE
LARKMAN MOY of 82 Stirling Street, New Clee, Grimsby in the County of Lincoln,
Master Mariner 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:-
The object of our invention is to provide a gear for instantaneously releasing ships
boats and the covers or tarpaulins from ships boats and the like.
Referring to the accompanying drawings and to the figures and letters of reference
marked thereon-
Figure 1 shews a perspective view of our improved " tumbler" catch or fastener as
hereinafter described.
Figure 2 shews a view of a part of a boat fitted according to our invention, the
cover being broken away for convenience, and for the purpose of shewing the applica-
tion of our improved appliance. In this figure for the sake of clearness, parts are
drawn out of proportion to other parts in the same figure and the figure "a
which is
merely to indicate the method of fastening, should of course be at the other end of the
boat in the case of two "tumblers" catches or fasteners at each side of the boat
being used.
In carrying out our invention we provide a "tumbler" catch or fastener constructed
substantially as shewn in Figure 1 of the accompanying drawings and consisting of a
plate or stand A of any convenient size, to this are fixed two upright plates B. B₁ for
the purpose of supporting between them the hinged or pivotted bar or pin C which
is pivotted at the rear portion of the apparatus by a pin or pivot D. These "tumblers
catches or fasteners are attached to the thwarts of the boats as clearly shewn in Fig. 2.
Any convenient number may be used as found to be desirable in practice.
"
We now provide a line, cord, chain, or the like E to which is attached at suitable
distances side lines G terminating in pins or "cottars" H adapted to fit into holes J
in the tumblers" catches or fasteners.

«
The cover K of the boat is provided with holes L through which are rove chains or
gripes" M corresponding in number to the "tumblers" catches or fasteners herein-
before described.
(1
To attach the boat to the ships deck and the cover K to the boat the end link of
the chain or gripe M is slipped over the pivotted pin or bar (as shewn in Fig. 1).
This pin or bar is then turned down on to the bed plate A and the pins or cottars" H
attached to the side lines G are inserted in the holes J in the "tumbler" catch or
fastener (this is fully illustrated by a Fig. 2). This operation is repeated for each
"tumbler "catch or fastener and the chains or "gripes" M are rove through the
boles L in the cover, and the free ends made fast to the deck of the ship thus securing
the boat to the ships deck and cover firmly to the boat. And in case of emergency it
is only necessary to pull one end of the line cord or chain E when the pins or
"cottars" H will be withdrawn from the "tumblers" catches or fasteners so releasing
the bar or pin C thus allowing the chains or gripes M to slip therefrom & the boat
& cover are then quite free and the boat ready for hoisting out into the water.
We may provide any suitable means for holding the cover to the stem and stern of
the boat preferably by means of pins at the ends of the main line, cord or chain E
passing through rings or the like in the ends of the cover.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
:-
I. In gear for securing & releasing boats & the covers of boats and the like, the
employment of a "tumbler" catch or fastener constructed substantially as herein

page_text: described, and adapted to secure the boat & cover to a boat or the like in the manner
hereinbefore described and illustrated by the accompanying drawings.
II. The general arrangement and construction of parts constituting our improved
gear for securing & releasing ships boats & the covers of ships boats and the like
substantially as herein described and as illustrated by the accompanying drawings.
Dated this Eighth day of September 1890.
