Improved Boats' Booms and Lashings.
WILLIAM BELL, of G. L. Watson & Co. 108 West Regent Street, Glasgow,
Naval Architect, do hereby declare the nature of this invention to be as
follows:-
. I make the boom of wood or steel tube. At each end is fixed a brass or other
metal eye through which the davits pass through. The boom is held in any desired
vertical position by rings on the davits, secured by pinching screws. By this
means the boat can be put outboard or inboard without removing the boom.
Alternatively, I make the boom detachable from the eyes. On the boom I fit one or
more movable arms hooked on their upper ends to go over the gunwale of the boat
& act in the same manner as "gripes" in holding her down. These arms are
detachable and reversible to suit boat either inboard or outboard. They are padded
on the inner surface by preference with rubber. A rubber ring is also fixed at
centre of boom to protect the boat's side. Near each end of the boom I fit a metal
stud for hooking ou the "belts." On each "davit" is a swivel eye with a
stretching screw by which the other ends of the "belts" are secured and
tightened up.

WILLIAM BELL of G. L. Watson & Co. 108 West Regent Street Glasgow,
Naval Architect 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 :-
I make the boom of wood or steel tube. At each end is fixed a brass or other
metal eye through which the davits pass through. The boom is held in any desired
vertical position by rings on the davits secured by pinching screws. By this means
the boat can be put outboard or inboard without removing the boom. Alternatively
I make the boom detachable from the eyes. On the boom I fit one or more movable
arms hooked on their upper ends, to go over the gunwale of the boat and act in the
same manner as "gripes" in holding her down. These arms are detachable and
reversable to suit boat either inboard or outboard. They are padded on the inner
surface, by preference, with rubber. A rubber ring is also fixed at centre of boom
to protect the boats side. Near each end of the boom I fit a metal stud for hooking
on the "belts" on each davit is a swivel eye with a stretching screw by which the
other ends of the "belts" are secured and tightened up.
I will now describe my invention with reference to the accompanying drawing.
Figs. 1. and 2. represent in elevation and plan the end of the boom a, attached

page_text: to the davit b. On the end of the boom a, I provide a metal eye è, jointed, with a
pin d, so that the said boom a, can be removed from the davit b, if desired. On
the davit b, I provide movable metal rings e and el secured by pinching screws,
to hold the boom vertically, in position, or alternatively, I may provide pinching
screws to the eyes on the davits, in which case the metal eyes e and el can be
dispensed with.
Figs. 3 and 4 shew a section and plan of the boom in way of one of the padded
arms with a portion of the boats side pressing thereon. The pad h, which may be
of rubber or any other suitable material, is secured to the boom by a metal arm J,
bolted to a metal ring K. travelling freely on the boom and so constructed that the
pad can be reversed or detached from the boom. I provide a grip hook g on the
padded arm h, to pass over the gunwale or top of the boat's side, e, to prevent
the said boat rising when the "belts" which secure same are tightened up, or a
sea strikes the boat. When the boat is secured to the boom outboard, and it is
desired to reverse it to inboard, all that is necessary is, to lower the boom, until the
boat's keel will pass over it. Then the davits can be turned round in the usual
manner. The boom is then raised again to its former position, the padded arms are
revolved on the boom and the grip hooks unfastened and refastened on the opposite
ends of the arms, the "belts "can then be tightened up and the boat secured as
before.
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.) The mode or manner of attaching the boom to the davits in such a way
that the davits can be turned round and the boat swung inboard or outboard
without unfastening or removing the boom from the davits.
(2.) The mode or manner of forming and attaching to the boom, the padded arms
for protecting the boat's side when secured to the boom, so that they can be
revolved, reversed or detached.
(3.) The mode or manner of holding down the boat by means of hooks or "grips"
attached to the padded arms.
(4.) The combination of parts as substantially described and illustrated herein
for securing boats, suspended from davits, on shipboard, so that said boats can
readily be swung inboard or outboard and secured in either position, without
detaching the boom from the davits.
Dated this 30th day of November 1896.
