Befcription of an Engine for rating Water by the lateral Motion of a Stream of Water 

 through a conital Tube In two Letters from Mr. William Close,

ART of this town being fituated upon a dry eminence of lime-ftone, the inhabitants 

 experience confiderable fatigue and inconvenience in providing the quantity of water 

 which is indifpenfibly neceflary for culinary and domeftic purpofes. There are excellent 

 fprings in the neighbourhood, and at a fmall diftance, if taken in a dire£t line, but the 

 neareft road to return is fteep and incommodious. This fituation has frequently turned 

 my attention to the contemplation of hydraulic machinery to remove the inconvenience, 

 and I doubt not it might eafily be done by various methods, as a ftream of confiderable 

 force runs very near the fprings, and the height to which water might be raifed with 

 confiderable advantage is not great : but this is not the objecl of my communication. 



The experiments of Citizen Venturi on the lateral motion of fluids, induce me to think 

 that an hydraulic engine, operating by the prelTure of the atmofphere, and in this refpedl 

 fimiiar to that excellent one invented by H. Goodwin, Efq. * may be brought into adion 

 by this principle. With this view I have made fome experiments, and endeavoured to 

 reduce my ideas into the form of an engine, which I expeft to fee much improved, and 

 of which I fend you a drawing and defcription. 



A A, in Plate XIII. Fig. i, reprefents a refervoir of water, kept conftantJy full, at the 

 fame time that the jet B is running full under a confiderable preflure. 



C a tube fixed into the bottom of the fpherical veflel D, and pafling up to fome height 

 above its middle. 



E another tube fixed into the bottom of D, and ending near its top. The lower part of 

 this tube is bended, and the extremity of it is introduced into the fmaller aperture of the 

 conical tube B. 



F a pipe to empty the veflel D, when filled with water.
