Página 288 - Mr. Wilkinson has bored us several cylinders almost without error ; that of 50 inches diameter, which we have put up at Tipton, does not err the thickness of an old shilling in any part.
Página 168 - I intend, in many cases, to employ the expansive force of steam to press on the pistons, or whatever may be used instead of them, in the same manner as the pressure of the atmosphere is now employed in common fire engines. In cases where cold water cannot be had in plenty, the engines may be wrought by this force of steam only, by discharging the steam into the open air, after it has done its office.

And a man that tends the work is but to turn two cocks, that one vessel of water being consumed, another begins to force and re-fill with cold water, and so successively, the fire being tended and kept constant, which the self-same person may likewise abundantly perform in the interim between the necessity of turning the said cocks.

Página 213 - I perceived, that in order to make the best use of steam, it was necessary, first, that the cylinder should be maintained always as hot as the steam which entered it ; and secondly, that when the steam was condensed, the water of which it was composed, and the injection itself, should be cooled down to 100°, or lower, where that was possible.
