page_text: CHURCHMAN'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting.
WHEREAS our Sovereign Lord George the Second, King of Great Britain,
and so forth, hath by His Letters Patent passed under His Great Seal of
Great Britain, bearing date at Westminster, the One-and-twentieth day of
March, in the sixth year of His reigne, given and granted unto me,
Walter Churchman, a Citizen of Bristoll, my executors, administrators, and
assignes, the sole use and benefit of my new Invention of "A MACHINE OR
ENGE TO BE MOVED OR WORKED BY THE UNITED POWERS OF WEIGHT AND
DRAUGHT FOR RAISING WATER FOR ANY USES, AND FOR DRAINING OF LOW LANDS,
COAL PITTS, AND MINES, AND FOR GRINDING, STAMPING AND ALL OTHER WORKS
WHEREIN ALL OR ANY OF THE MECHANICALL POWERS ARE OR MAY BE APPLIED,"
within that part of His Majestie's Kingdom of Great Brittain called England,
His Dominion of Wales, and Town of Berwick-upon-Tweed, for and during
the terme of fourteen years, according to the Statute in such case made and
provided; in which said Letters Patent there is a proviso in the words or
to the effect following (that is to say), Provided also that if the said Walter
Churchman do not particularly describe and ascertain the nature of his said
Invention, by an instrument or writing under his hand and seal, to be inrolled
in Our High Court of Chancery within two calendar months from the date
of these Our Letters Patent, then and in such case these Our Letters Patent
shall forthwith cease, determine, and be utterly void to all intents and
purposes, anything herein-before contained to the contrary thereof in anywise.
notwithstanding, as by the said recited Letters Patent (relation being there-
unto had) may more fully and at large appear.
NOW KNOW YEE, that I, the said Walter Churchman, in obedience to
and in pursuance of the said recited Letters Patent, do hereby declare that my

page_text: said Invention is composed and consists of a large walking wheel of
weight and draught for cattle to draw in or upon the same, their harness to
be fastned to a post, bar, or to arms through a slit or groove in the
middle of this wheel, and at the sides and on the top of it; this wheel, double
ringed and cogged, shall move a spirall pump (with one, two, three, or four
wreathed partitions in it), and shall work levers, chains, springs, catches,
swivells, screws and their boxes, directors and regulators, as also two or
more wallows fixed on horizontal shafts with small wheels on the same, all
turning and sliding on and in a frame, in order thereby, with the severall
wheels on those horizontall shafts, to elevate and depress alternately the severall
teethed lifters, forcers, racks, and rods (with a leveridge back wheel to each)
in the different pumps, cylinders, and other vessells to be employed to raise
the water by this method for any use or purposes, which water thus raised
shall occasionally be throwne into a reservoir or imediatly on bucketts or
ladles fixed on another wheel to be joined in the work in order further by the
weight of such water to gain an additionall power.
In witness whereof, I, the said Walter Churchman, have hereunto set
my hand and seal at Bristoll, the Seventh day of May, in the said
sixth year of His Majestie's reign, and in the year of our Lord One
thousand seven hundred and thirty-three.
