Page 24 - I believe it may be made very useful to ships, but I dare not meddle with that matter; and leave it to the judgment of those who are the best judges of maritime affairs;" and he further remarks, " As for fixing the Engines in Ships, when they 1698.
Page 11 - An admirable and most forcible way to drive up water by fire, not by drawing or sucking it upwards, for that must be as the philosopher calleth it, infra spheeram activitatis, which is but at such a distance. But this way hath no bounder, if the vessels be strong enough ; for I have taken a piece of a whole cannon, whereof the end was burst, and filled it...
Page 11 - I have seen the water run like a constant fountain-stream forty feet high ; one vessel of •water rarified by fire, driveth up forty of cold water. 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 refill 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.
Page 28 - Papin's digester, and formed a species of steam-engine by fixing upon it a syringe, one-third of an inch diameter, with a solid piston, and furnished also with a cock to admit the steam from the digester, or shut it off at pleasure, as well as to open a communication from the inside of the syringe to the open air, by which the steam contained in the syringe might escape. When the communication between the digester and syringe was opened, the steam entered the syringe, and by its action upon the piston...
Page 15 - ... far is the vessel dry without, and so very hot, as scarce to endure the least touch of the hand. But as far as the water is, the said vessel will be cold and wet where any water has fallen on it ; which cold and moisture vanishes as fast as the steam in its descent takes...
Page 28 - My attention was first directed in the year 1759 to the subject of steam-engines, by the late Dr Robison, then a student in the University of Glasgow, and nearly of my own age. He at that time threw out an idea of applying the power of the steam-engine to the moving of wheel-carriages, and to other purposes, but the scheme was not matured, and was soon abandoned on his going abroad.
Page 14 - The first thing is, to fix the engine in a good double furnace, so contrived that the flame of your fire may circulate round, and encompass your boilers, as you do coppers for brewing. Before you make any fire, unscrew G and N, being the two small gauge pipes and cocks belonging to the two boilers, and at the holes fill L, the large boiler, two-thirds full of water, and D, the small boiler, quite full.
Page 11 - So that, having a way to make my vessels so that they are strengthened by the force within them, and the one to fill after the other, I have seen the water run like a constant fountain stream forty feet high.
Page 29 - ... the engine would work regularly with a moderate quantity of injection. It now appeared that the cylinder of the model, being of brass, would conduct heat much better than the cast-iron cylinders of larger engines, (generally covered on the inside with a stony crust,) and that considerable advantage could be gained by making the cylinders of some substance that would receive and give out heat slowly.
Page 28 - Ibs.) with which it was loaded. When this was raised as high as was thought proper, the communication with the digester was shut, and that with the atmosphere opened; the steam then made its escape, and the weight descended. The operations were repeated, and, though in this experiment the cock was, turned by hand, it was easy to see how it could be done by the machine itself, and to make it work with perfect regularity.
