IMPROVEMENTS IN BLOCKS AND SHEAVES
Year: 1849

page_text: DHAUL COME,1, ENKY
MILLS STOWE, of Bermuda, Master of the Brig Jane, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent, under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twentieth day of June,
One thousand eight hundred and forty-nine, in the thirteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Mills Stowe, my exors, adiñors, and assigns, Her especial licence,
full power, sole privilege and authority, that I, the said Henry Mills Stowe, my
exors, adñiors, and assigns, and such others as I, the said Henry Mills Stowe,
my exors, adiñors, or assigns, should at any time agree with and no others, from
time to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN BLOCKS
AND SHEAVES;" in which Letters Patent is contained a proviso that I, the said
Henry Mills Stowe, should cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, by an instru-
ment in writing, under my hand and seal,, to be inrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Mills Stowe, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described and

page_text: To reference being had to
the Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention consists, first, of improvements in blocks; and,
Secondly, my Invention consists of improvements in sheaves.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued by me :-
DESCRIPTION OF THE DRAWING.
'
Figures 1 and 2 show two views of a block constructed according to my
Invention; and Figure 3 shows two views of the metal fork which receives the
pin or axis of the sheave, and consequently takes the whole pressure, the wood
portions of the block taking no pressure. a is the metal fork; b, the pin
or axis of the sheave, which secures, all parts together,, and by having the pin
or axis with a head at one end and a cotter at the other, ready means of
allowing the pin or axis to be withdrawn are provided for separating the parts,
and the parts of the block may also readily be put together again. When a
block is to have two or more sheaves, then I prefer the fork to have three or
more legs, so. that there will be a metal bearing to the axis or pin of the
sheaves on either side of the block and of each sheave, but this is not abso-
lutely necessary, as. the fork may, if desired, have only two legs for the outside
of the block when more than one sheave is employed.
When using a fork, such as is, shewn at Figures 1, 2, and 3, for single
blocks, I prefer to cause it to be applied externally of the block, for which
purpose the external parts of the block will be hollowed out to receive the legs
of the fork, as shewn, but if desired, be let into the interior of the block.
The improvement in sheaves are shewn in Figures 4 and 5, and consists of
the mode of constructing bushings of sheaves. The bushing is made in one
piece .c, as shewn, and it is screwed into the sheave forming the bush, as will
readily be understood on examining the Drawing.
Having thus described the nature of my Invention; and the manner of per-
forming the same, I would have it understood that what I claim is,-
First, the improvements in blocks, herein described.
Secondly, I claim the improvements in sheaves, herein described.
In witness whereof, I, the said Henry Mills Stowe, have hereunto set
my hand and seal, this Nineteenth day of November, in the year of
our Lord One thousand eight hundred and forty-nine.
HENRY MILLS (L.S.) STOWE.
