PROVISIONAL SPECIFICATION.
Improvements in Means for Attaching Gaffs or Booms to the Masts
of Ships or other Vessels.
JOHN ELLIS Beach Road Hirael Bangor N.W. Sailmaker do hereby declare
the nature of this invention to be as follows:-
:-
It is intended to supersede jaws on gaffs of yachts, ships, steamers, and all
classes of sailing vessels. The bucket cau be made of wood or malleable iron, if
made of wood, it can be made in sections of two, four, or more sections according
to size. The wood bucket is bound with two iron hoops or bands the upper hoop
has a universal joint where the gaff which is shod with an iron shoe ships into
forming one joint, and works perpendicular to the mast.
The bolt for the main halyards forms the pin for the other joint which is on the
upper hoop and works horizontal to the mast, leaving the bucket to hang with ease;
the lower hoop has an eye for the throat of the sail to shackle on to; "the bucket
can be made of any depth."

Improvements in Means for Attaching Gaffs or Booms to the Masts
of Ships or other Vessels.
I JOHN ELLIS of Beach Road Hirael, Bangor in the County of Carnarvon,
North Wales, Sailmaker 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:-
This invention is intended to supersede the ordinary jaws used on gaffs and
booms of yachts, ships, steamers and all classes of sailing vessels. The bucket
jaws can be made of either wood or malleable iron. They can be made in two,
four or more sections according to size. The wooden bucket is bound with two iron
hoops or bands, and the hoop has an universal joint, where the gaff or boom is shod
with an iron shoe which ships into a link forming one joint, and works in a direction
perpendicular to the mast; the bolt for the main halyards forms a pin for the
other joint which is on the hoop and works in a horizontal plane, leaving the bucket
to hang with ease. The hoop has an eye for the throat of the sail to shackle onto,
and the bucket can be made of any depth.
In order that my invention may be fully understood, I append drawings in
which
Fig. 1. is a plan, and
Fig. 2. an elevation of a wooden bucket jaw.
Fig. 3. is a plan, and
Fig. 4. is an elevation of a metal bucket jaw.

page_text: Where a wooden bucket is used as shewn in Fig. 1 & 2, it is encircled by oue or
more iron or other metallic hoops or bands A and the hoop has attached to it one
or more projections a, a (four are shewn in drawing) between which fit one or more
tongues, of the link B. Through these projections a and tongues b passes the
vertical pin C, which forms a pivot, and allows of the horizontal movement of
the gaff or boom E with the link B; G is a horizontal pin by means of which the
heel e of the boom E is pivoted to the link B thus allowing of a free vertical
movement of the gaff or boom.
The whole thus forms an universal joint which permits of the free movement of
the gaff or boom in any direction.
To the horizontal pin G is attached loosely. the eye D which is used for the
throat of the sail to shackle on to.
The vertical pin C has an eye which forms its head, and to which the main
halyards are attached..
The hoops A may be made in halves and either fastened by bolts or hinged on
one side and bolted at the other.
Where no wood bucket is used the iron hoops or bands fit the mast as shewn in
Fig. 3 and 4, but the principle remains the same in either case.
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
claim is:
1. The bucket jaw substantially as described and shewn.
2. A bucket jaw or substitute for the gaff or boom jaws commonly used, con-
sisting essentially of a hoop or hoops encircling the mast, a gaff heel or shoe, and a
link or part so connected together that the whole forms an universal joint
substantially as described and shewn.
3. In a bucket jaw the combination of a hoop or hoops A encircling the mast
and having projections a therefrom, the vertical pin or pivot C, the link B, the
horizontal pin or pivot G, the gaff or boom heel e, and the eye D, substantially as
described and shewn.
