336 Mr. Perkins^ Method of applying his J^ew Invention ^c, 



pressure, and pa§s at once from the generator into the 

 steam pipe, where it becomes steam or vapour, and in that 

 form may pass thence to the cylinder, or to any other situ- 

 ation connected with a steam engine, without the necessary 

 intervention of any steam-chamber, or other reservoir ot 

 steam. 



" Thirdly, — For the manner of causing such water or 

 other fluid or fluids to escape as aforesaid, that is to say, by- 

 forcing other water or fluid or other fluids into the genera- 

 tor, until the pressure against the steam valve shall cause it to 

 rise, the valve being so loaded as not to rise, except by 

 means of such extra pressure as aforesaid. 



" Fourthly, — For the general application of such water, 

 or other fluid or fluids, so heated as aforesaid, and of the 

 steam or vapour generated thereby ; whether such steam or 

 vapour be employed through a steam-pipe without a 

 steam-chamber, or reservoir to act immediately on the 

 piston, or to be collected in areservoir or steam-chamber, 

 and thence to act on the piston, or only for heating wa- 

 ter to generate other steam, or for any other purpose or pur- 

 poses whatsoever, provided always, that such general ap- 

 plication as aforesaid be for the purposes of steam-en- 

 gines." 



The Editor of the London Journal of Arts, from which 

 we have taken the preceding specification, informs us, that 

 the mode of applying this principle to a variety of opera- 

 tions in which heating may be requisite, is embraced 

 by a second patent to be specified in November, and that 

 the mechanical construction of the working parts of the en- 

 gine will be explained in the specification of the third pa- 

 tent, which will be enrolled in December. 



The same writer informs us, that several of the new en- 

 gines which have been ordered, are at present constructing; 

 and particularly, that an engine of about 80-horse power, 

 for the purposes of steam navigation, is in considerable for- 

 wardness, and will probably be in operation between Lon- 

 don and Margate before the end of the present summer.
