Year: 1768

page_text: WISE'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
WISE, of the Town and County of the Town of Nottingham, Musician, send
greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date the
Fourteenth day of March, in the eighth year of His reign, did give and grant
unto me, the said Samuel Wise, His especial licence that I, the said Samuel
Wise, during the term of years therein expressed, should and lawfully might
use, exercise, and vend, within England, Wales, and Town of Berwick-
upon-Tweed, my Invention of "A MACHINE OR ENGINE UPON AN ENTIRE NEW
CONSTRUCTION FOR THE USE OF RAISING WATER OUT OF MINES AND WELLS, AND
DRAINING LANDS;" in which said Letters Patent there is contained a provisoe
obliging me, the said Samuel Wise, under my hand and seal, to cause a par-
ticular description of the nature of iny said Invention, and how the same is to
be performed, to be inrolled in His Maty's High Court of Chancery, within
four calendar months 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Wise, do hereby declare that my said Invention of a Machine or
Engine upon an entire New Construction for the Use of Raising Water out of
Mines and Wells, and Draining Lands, is described in the plan thereof hereunto
annexed.
In witness whereof, I, the said Samuel Wise, have hereunto set my hand
and seal, this Nineteenth day of April, One thousand seven hundred
D
SAM. WISE. (Ls.)

in the year above mentioned, the aforesaid Samuel Wise came before our said
Lord the King in His Chancery, & acknowledged the Specification aforesaid,
and all and every thing therein contained, in form above written. And also
the Specification afores was stampt according to the tenor of the Statute
made in the Sixth year of the reign of the late King and Queen William and
Mary of England, and so forth.

Oxen &c. The upper gugeon is seen at C. but the lower gugeon cannot be seen in the figure,
being hid by the thickness of the Wheel. A.B.
DE. is another axis, on which are two trandle heads F.H. and GI. and also a
wheel near the centre over which the chains that work the pumps M.N.pass. one of these
chains is seen at L. but the other being directly behind it cannot be seen in the figure, The
two trundles F.H.G.I. have staves only half round, the other parts being open, as expressed
in the figure.
.
When the wheel A.B. is turned round it will cause an alternate motion in the axis
D.E. by means of the coggs in the wheel A.B. taking hold of the staves in the trundle Alter
-nately; and consequently cause the pistons of the pamps M.N to rise and fall alternately, The
advantage of this machine consists in the length of the stroke, which is made in the same time
and with the same power as with a crank, but as the length of the stroke in this machine is equal
to the semiperiphery of the wheel K, and the length of the stroke, if a crank had been used, equal
only to the diameter of the same wheel as 0.P. it follows that the length of the stroke in this ma-
-chine, exceeds the length of the stroke when a crank used, as much as the semiperiphery of
any circle exceeds its diameter; but the semiperiphery of any circle is to its diameter as 1.5.7.
to 1, consequently the stroke in this machine will be above one third longer, and therefore the
quantity of water raised one thard more than that raised by the common method For if the length
of a stroke of a crank be two feet, the length of the stroke by this contrivance, will be some-
thing more than three.
.
It is intended to add more pumps when large quantities of water are to be raised; but
as they will be work'd by the same principle, it was thought innecessary to render the
figure confased by a multiplicity of parts and references.
