Apparatus for raising water. 21 



WW, a well or pit fituated below the bed or lower level Defcription of 

 of the ftreamlet ; its depth varying from 6 to 20 feet, accor d- ^nfl^&^j fo! 

 ing to the elevation to which water is to be raifed above theraifing water, 

 ciflern, and the number of proereflive columns by which it by a,r . co " dcnie <l 



1 to J in an inverted 



is to afcend. fyphon. 



A A, a pipe leading from the ciflern R, to a bell-fhaped 

 veflel B, fixed a little above the bottom of the well, with its 

 mouth downwards. The top of the pipe is crooked, as re- 

 prefented at A, Fig. 5, and there is a joint below, which 

 allows the crooked part to be detached from the reft. The 

 lower end of this pipe is alfo crooked, and turns under the fide 

 of the veflel B. 



C C, a pipe fixed into the top of the veflel B, and carried 

 a little above the ciflern, where two fmaller pipes, E and G, 

 are connected with it by a ftop-cock. 



E, a fmall pipe leading to F, a veflel cr chamber, placed 

 in the ciflern R. 



G, another fmall pipe leading to H, a veflel or chamber, 

 fomewhat lefs than F, placed in a higher fituation. This pipe 

 has a turn, a foot above the top of the veflel H. 

 I, a pipe leading from the ciflern R to the veflel F. 

 K K, a pipe defcending a foot or more below the veflel F, 

 and then afcending to the veflel H. 



L, a pipe connected to K, a foot below H, and then car- 

 ried to the conduit or ciflern which receives the raifed water. 

 The pipes I, K, L, have each a valve opening upwards. 

 The conftruftion of the cock is reprefented in Fig. 3. The 

 conical barrel has four holes, C, E, G, O, and the turning 

 part or key, has a notch, or hollow, on each fide in that part 

 which moves oppofite thofe holes, lb that the pipes C and E, 

 or C and G, may be connected by a quarter of a turn. When 

 the communication opens between C and E, the external air 

 has accefs to the infide of the pipe G, and to the chamber H 

 above, through the opening O ; and when C is joined to G, 

 the air is admitted into the chamber F, through the opening 

 O, and the pipe E. 



In the narroweft part of the veflel B, a buoy or float is fixed 

 upon the elevated end of a crooked lever, moving upon a ho- 

 rizontal axis, fupported by pieces attached to the fide of the 

 veflel. Inflead, however, of a common hollow buoy, it will 

 be preferable to ufe a body fpecifically heavier than water, and
