A Deſcription of the Engine for raiſing vvater by Fire.

A The Fire place.

B. A. large Boiler or alembic, three parts full of wa-
ter, the Steam wereof is confined by a cloſe ſpherical
Top, and kept of a due uniform force.

C. A Braſſ cylinder, woſe diameter is more or leſſ,
according to the Depth and Quantity of water, to be
drawn in ſuch proportion, that the Preſſure of
the atmoſphere upon the area of its baſe may over-
poiſe and raiſe the pillar of water with a proper ve-
locity.

D. The Pipe thro which the Steam paſſes from the
Boiler into the cylinder.

E. The axis of the regulator, that opens and ſhuts
that End of the Pipe D, within the Boiler, wich re-
gulates the whole motion of the Engine, by permit-
ting the Steam, to aſcend and puſh up, or ſuffer the
Piſton to riſe, and confining the Steam when riſen,
in order to its condenſation, by an injection of cold
water, which making a Vacuum there, the pi-
ſton is immediately depreſſed by the Wight of the
atmoſphere.

F. A loaded Value, which giues Vent to the Steam
of the Boiler, in caſe it grows to ſtrong.

G. Two Gage Cocks with their Pipes, on of
which goes down, ſo far into the Boiler, as to be,
