Fig. 1 is a perspective view, and fig. 2 

 a .section of the working parts. 



The pump is attached to a board or 

 scantling, A, secured to the side of the 

 well or otherwise, as may be desired, and 

 is worked by a handle, to which, at equal 

 distances from the centre, two rods, F, 

 are connected by a turnbuckle, their 

 other ends being connected to the moving 

 lever, E, of the pump, which works on a 

 pin, G. This lever E is T-shaped, and 

 moves through a space, I, in the air- 

 chamber, H, cast to receive it. The 

 pump-barrel, B, has closed ends, D, and 

 the double piston, C, with its valves, J, 

 works horizontally therein. KK are the 

 valves of the air-chamber. The operation 

 is as follows : 



The pump is immersed in water, and 

 the handle being given a reciprocating 

 motion, the T-piece, E, receives a similar 

 one through the rods, F. This gives the 

 piston a horizontal back and forth mo- 

 tion, at each of which it takes in a quan- 

 tity of water and forces it into the air-chamber, and thence through the pipe 

 upwards, to any height. To this pipe a hose is here attached to show how it 

 throws water, &c.
