8979DE MACHINA HYDRAVL. LONDINENSI.
Receiver P1, There is nothing there to countrebal-
lance, the preſſure of the Atmoſphere, on the ſurface
of the Water, in the lower Part of the Suking Pipe T;
where fore it will be preſſed up, and aſcend into, and
fill the Receiver P1, driving out before it as it raiſes,
the Clack or Valve R3, which afterwards falling down
again and ſhutting cloſe hinders the deſcent of the wa-
ter that way. Then (the Receiver P2, being in the
mean time emptied of its Air) turn the handle of the
Regulator from you, and the Force of the Steam co-
ming from the Boyler, will be all upon the ſurface of the
Water contained in the Receiver P1, where it grauita-
tes or preſſes hard upon it, and ſtill encreaſes, its Spring
or elaſticity, till it comes to overballance, or exceed
the Weight of the Water into the Receiver, which
then it will neceffarly drive up through the Paſſage Q,
R, Q, Q, into the Force Pipe S, and at laſt diſcharge it
out at the Top, as you ſee in the Figure.

After the very ſame manner, tho alternately, is the
Receiver P2 filled with, and emptied of Water, and
by this Means a conſtant Steam is kept continually
running out at the Top of the Force Pipe S, and ſo the
water is raiſed very eaſily from the bottom of the mine
etc. to the place, where it is deſigned to be diſcharged.

Only 1 ſhould add, that after the Engine begins to
work, and the water is ſen into, and hath filled the
Force Pipe S, then it fills the little Ciſtern X, and by
that means feeds the Pipe yy, which he calls the con-
denſing Pipe, becauſe Water is conveyed down from
thence, to cool the receivers, when troughly heated
by the Steam, in order to make them Suck (at t'is u-
ſually called) the Water out of the well up into the
Receiver.
