SAFELY DETACHING AND ATTACHING SHIPS' BOATS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, JAMES LINKLETER 60 Hotspur St. Tynemouth, Patentee and Manufacturer of
Detaching Gear & do hereby declare the. nature of my invention for SAFELY
DETACHING AND ATTACHING SHIPS' BOATS to be as follows: - .
My invention has for its object-To simplify; and with the fewest working parts,
place the safe and instantaneous detaching of a ship's boat, entirely under the
control of one man. It is so arranged that (1) The man in charge can stand with
the Detaching Gear in one hand, and the belm in the other ready for steering the
boat clear of the ship's side. (2) He can either hold on or let go at will. (3) The
boat can be safely attached to the blocks after coming along-side the ship again.
I attach a Tumbling Hook to the fore-end of the boat, with a chain or wire-rope
attached to the tail for the purpose of holding and controlling the hook, similar
to that used by me in Patent 2234, 1883..
The opposite end of this chain or rope is taken aft and secured with the lower
block to a hook fixed in the boat, in such a manner that the unhooking of one
instantly releases the other.
The chief advantage of this gear is,-That it can be worked through a pipe or
tube, attached to the thawta"; so as to keep the connection clear of the passengers
in the boat, thereby doing away with the complicated arrangements used in the
bottom of the boat for this purpose.

I, JAMES LINKLETER of 60 Hotspur Street Tynemouth in the County of
Northumberland Patentee and Manufacturer do hereby declare the nature of my
invention for "SAFELY DETACHING AND ATTACHING SHIPS' BOATS 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 certain mode of connecting the hooks by which the
boat is suspended from the Davits, so as to insure the simultaneous detaching of
the two ends; putting the boat under the control of one man at the helm, who may
either prevent the boat detaching itself from the Davits, or, allowing it to detach,
may have complete control over the steering to clear it of the ship's sides.
In the fore-end of the boat there is a tumbling hook, resembling that shown in
my Patent No. 2234/'83. This tumbling hook is held in position by a chain or
wire line, which runs fore to aft of the boat, and can be worked either over the
thwarts or through a tube under the thwarts to keep clear of the passengers. On
the opposite or after-end of this line there is a large link through which the link
on the lower after-block is reeved, and then passed on to the hook fixed in the
after-end of the boat. When the boat is lowered into the water and afloat at both
ends the connecting line guides the link on the lower block off the hook. The one
link then unreeves itself out of the other and allows the hook in the fore-end of
the boat to tumble.
The hook in the after-end of the boat may be either a fixed hook or a slip-hook.
When used as a slipping-gear I use a hook resembling that shewn as "centre-
.hook" in Fig. 1 of my drawings in Patent 2234/'83.
First. When the boat is required to be dropped from the Davits.
By pressing down the lever, the connecting line and after lower block are released
together, allowing the boat to drop level.
Second. When the boat is lowered into the water.
Immediately the boat is completely water-borne the lever falls by its own
weight, thus releasing the connecting line and the after lower block together.
If required to be kept alongside, the boat may be prevented from detaching
itself by simply keeping the pin or stopper in the point of the hook, (Fig. 1.
No. 2234/'83).
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) Keeping Tumbling hook in fore-end of boat in position by connecting line
attached with after block to the same hook.
(2) Releasing the fore-and-after ends of the boat simultaneously from one and
the same hook in the after end of boat.
