Morrison, all of North Shields, in the County of Northumberland, for
the Invention of "IMPROVEMENTS IN REEFING AND STOWING JIB SAILS FROM
Morrison, all of North Shields, in the County of Northumberland, for
the Invention of "IMPROVEMENTS IN REEFING AND STOWING JIB SAILS FROM
THE DECK.
Sealed the 16th June 1865, and dated the 19th December 1864.
PROVISIONAL SPECIFICATION left by the said John Butchart, Henry
Stroud, and Samuel Allen Morrison at the Office of the Commissioners
of Patents, with their Petition, on the 19th December 1864.
We, JOHN BUTCHART, HENRY STROUD, and SAMUEL ALLEN MORRISON, all
of North Shields, in the County of Northumberland, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN REEPING AND STOWING JIB
SAILS FROM THE DECK," to be as follows:--
This Invention relates to improvements in the method of reefing and
stowing jib sails from the deck, and consists in attaching a swivel block to
the upper part of the jib stay, such block being connected to the mast by the
jib halyards, and in applying at the lower part of the jib stay a whelped
sheave with swivel attached to the hoop or hounds of the boom; on the
boom near or under the whelped sheave are two leading blocks for the reefing
chains to pass through and over the sheave; the ends of the reefing chains
are attached to two blocks, thus it will follow that by hauling on the reefing

page_text: ohains the whelped sheave will be caused to revolve, and the stay being free
at the upper part with the swivel the stay will revolve and take up the sail,
and vice versa.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Butchart, Henry Stroud, and Samuel Allen Morrison
in the Great Seal Patent Office on the 19th June 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
BUTCHART, HENRY STROUD, and SAMUEL ALLEN MORRISON, all of North
Shields, in the County of Northumberland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said John Butchart, Henry Stroud, and Samuel Allen Morrison, Her
special licence that we, the said John Butchart, Henry Stroud, and Samuel
Allen Morrison, our executors, administrators, and assigns, or such others
as we, the said John Butchart, Henry Stroud, and Samuel Allen Morrison,
our executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
REEFING AND STOWING JIB SAILS FROM THE DECK," upon the condition (amongst
others) that we, the said John Butchart, Henry Stroud, and Samuel Allen
Morrison, our executors or administrators, by an instrument in writing under
our, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Butchart, Henry Stroud, and
Samuel Allen Morrison, do hereby declare the nature of our said 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 relates to improvements in the method of reefing and
stowing jib sails from the deck, and consists in attaching a swivel block to

page_text: the upper part of the jib stay, such block being connected to the mast by the
jib halyards, and in applying at the lower part of the jib stay a whelped
sheave with swivel attached to the hoop or hounds of the boom; on the
boom near or under the whelped sheave are two leading blocks for the reefing
chains to pass through and over the sheave; the ends of the reefing chains
are attached to two blocks, thus it will follow that by hauling on the reefing
chains the whelped sheave will be caused to revolve, and the stay being free
at the upper part with the swivel the stay will revolve and take up
the sail,
and vice versa.
In order that our said Invention may be completely understood we annex a
Sheet of Drawings, in which, at Fig. 1, A represents a swivel block attached to
the upper part of jib stay; B, the wh elped sheave with swivel attached to
hoop on hounds of jiboom, this sheave is shewn enlarged at Fig. 2; C, C, are
two leading blocks attached to hoop F, and are shewn more clearly in the
enlarged Fig. 3; D, D, are two blocks attached to the reefing chains; E is
the arm to support the sheave B; F is the hoop or jiboom with leading
blocks C, C, attached; the arm E is shewn more clearly in Fig. 4.
By this Invention no halyards, banks, or down haul is required, the sail
being fixed to jib stay. The reefing chains pass through the leading
blocks C, C, and over the whelped sheave B, and the stay being free at
upper part with swivel A, by hauling on the reefing purchase D, D, it is
made to revolve, and so reef or stow the sail.
We claim the "Improvements in Reefing and Stowing Jib Sails from the
Deck," substantially as herein specified.
In witness whereof, we, the said John Butchart, Henry Stroud, and
Samuel Allen Morrison, have hereunto set our hands and seals, this
Sixteenth day of June in the year of our Lord One thousand eight
hundred and sixty-five.
