page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
DAWSON, of Rownham Place, in the Parish of Clifton, in the County of
Gloucester, Mechanic, do send greeting.
WHEREAS His most Excellent Majesty George the Third, by His Letters.
Patent under the Great Seal of the United Kingdom of Great Britain and
Ireland, bearing date at Westminster, the Third day of July now last past,
did give and grant unto me, the said Robert Dawson, my executors, adminis-
trators, and assigns, His special licence, full power, sole privilege and
authority, that I, the said Robert Dawson, my executors, administrators, and
assigns, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, and also in His
Majesty's Colonies and Plantations abroad, my Invention of "A MODE OF
APPLYING ANY MOVING POWER TO MACHINERY, AND OF INCREASING SUCH POWER,
AND OF RENDERING MACHINERY MORE EASILY SUSCEPTIBLE OF A MULTIPLICITY OF
SUCH POWER AT THE SAME OR DIFFERENT PERIODS;" in which said Letters
Patent there is contained a proviso obliging me, the said Robert Dawson,
under my hand and seal, to cause a particular description of the nature of
my said Invention, and the manner in which the same is to be performed, to be
enrolled in His Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said recited Letters Patent,
as in and by the same, relation being thereunto had, may more fully and at
large appear:

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Dawson, do hereby declare that my said Invention is fully described
and ascertained in manner following, and by the Drawings in the margin
hereof, that is to say:-
In situations whero power is required to be applied to machinery, and water
cannot conveniently be had, I erect an upright spindle in a suitable fram-
ing, in which it is to turn, and so placed that motion from the said spindle
can most easily, according to circumstances, be applied to the machinery to
which power is wanted. This spindle rises into the open air, where I construct
on it a framing in sockets, by which it revolves round the spindle horizontally;
and in this framing I place vanes turning by means of spindles fastened to
them vertically in the said horizontal framing, which permit them to turn
round in their framing according as the wind presses on them. When the
wind blows against these vanes there is a bearing that runs from the horizontal
framing to the upright spindle, to which being fixed, the whole is caused to
revolve together at a rate according to the strength of the wind. When this
bearing is made tight and slipped into a groove, the wind acts upon the vane
to which the bearing has reference, and power is gained from its operation on
this vane. When the bearing is slipped out of the groove the bearing slips
back, when the vane comes against the wind, and the same, keeping its edge to
the wind, is out of power. As the bearings and vanes are increased so is the
power; each vane that is added to be so placed that each overlaps the other a
little, and from each vane a bearing runs to the spindle, and the power is by means
of them increased or diminished, as required. By this construction of apparatus
the whole force of the wind is received on the full surface of the vanes, and as
the framing revolves the vanes turn, and present nothing on the contrary side
of the spindle to the wind but their edges. In situations where there is a
running stream to be applied as a first mover, instead of causing the spindle to
rise in the open air I make it to descend into the water, and thereon affix
similar apparatus, as above described, excepting that I place the stays above
the apparatus, as in the wind machine. By this contrivance the stream will
operate in the same way as the wind does on the other construction, and in
situations where I wish to obtain the power of wind as well as that of the
stream I lengthen the spindle so as to rise into the open air, and to descend
into the water, and affix on each end of it apparatus, as above described.
The Drawings in the margin of these presents, and the following description
thereof, will more clearly elucidate and define the nature of my Invention :-

be acted on by water, Fig. 3 is a view of the apparatus applied to the navi-
