Σελίδα 85 - 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.
Σελίδα 95 - I employ the steam, after it has acted in the first vessel, to operate a second time in the other, by permitting it to expand itself, which I do by connecting the vessels together, and forming proper channels and apertures, whereby the steam shall occasionally go in and out of the said vessels.
Σελίδα 9 - ... hours it burst and made a great crack ; so that, having a way to make my vessels so that they are strengthened by the force within them, and...
Σελίδα 48 - 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...
Σελίδα 594 - Liverpool, setting forth that they considered " the present establishments for the transport of goods quite inadequate, and that a new line of conveyance has become absolutely necessary to conduct the increasing trade of the country with speed, certainty, and economy.
Σελίδα 770 - Commons was appointed in 1819, "to inquire how far it might be practicable to compel persons using steam engines and furnaces in their different works, to erect them in a manner less prejudicial to public health and comfort, and to report their observations thereupon to the House.
Σελίδα 761 - Lastly, be it remembered, that my said new invention consists only in the method of consuming the smoke, and increasing the heat, by causing the smoke and flame of the fresh fuel to pass through very hot funnels or pipes, or among, through, or near, fuel which is intensely hot, and which has ceased to smoke ; and by mixing it with fresh air when in these circumstances...
Σελίδα 9 - 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.
Σελίδα 48 - ... (15 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.
Σελίδα 604 - The engine to be delivered complete for trial, at the Liverpool end of the railway, not later than the 1st. of October next. " 8th. — The price of the engine which may be accepted, not to exceed ^550. delivered on the railway; and any engine not approved, to be taken back by the owner. " NB — The Railway Company will provide the engine tender with a supply of water and fuel for the experiment. The distance within the rails is four feet eight inches and a half.
