Year: 1714

page_text: ANNE, by the grace of God, &c., to all to whom these Presents shall come
greeting.
WHEREAS our trusty and welbeloved JOHN COSTER, of Redbrooke, in our
County of Gloucester, Gentleman, and JOHN COSTER, junior, of Redruth, in
our County of Cornwall, Gentleman, have by their humble petition represented
vnto vs that they have with great paines and expences invented and brought
to perfection "AN ENGINE FOR DRAWING WATER OUT OF DEEP MINES MUCH
CHEAPER AND MORE EFFECTUALL THAN THE VSUALL WAYS BY WATER WHEELS;" in
which new invented engine the water that drives it is carried down the shaft
or pitt to the adit in bored clines and metall cillinders, and by that meanes
circulates a chain with bobbs through the said cillinders, which chain depend-
ing on a peculiar sort of wheele workes a cranke at each end of the axell
thereof, which said engine, with the application thereof for the drawing water
with sucking plumps, chaine plumps, and forcing plumps, is a new Invention,
not formerly known and practised in England, and being made for lesse charge
than water wheeles, and requiring much less room vnder ground, as well as lesse
charge to keep it in repair, and that it will with the same stream of water
draw at least one-third part more water in quantity from the same depth, or
one-third in depth more than water wheels with the same stream and fall can
or will do, the said engine will be of great vse for such mines as have been left
off for want of ability to draw the waters off them, the recovery and working
of which will be of great advantage to the nation in generall, as well as to the
lord of the royalties and persons adventuring in such mines, and haveing
