274 IRRIGATION FARMING. 



open check valve, it forces the same forward and closes it. 

 Its exit being thus cut off, the water by its momentum 

 raises the puppet valve and escapes through the opening, 

 whence it runs off in a reservoir or other receptacle. 

 During the time the regulator partially empties into the 

 pipe, causing a partial vacuum and a depression of the 

 corrugated heads ; but the pressure upon the clack valve 

 meanwhile diminishes, allowing it to be thrown open by 

 the weight on the level, so that the water immediately 

 fills the regulator again. The corrugated heads assume 

 their original positions and the same phenomena take 

 place again in a very brief period of time, varying from 

 four hundred to four hundred and fifty a minute. The 

 vibrations insure the continuity of the movement, caus- 

 ing an uninterrupted flow of water from the reservoir 

 over the puppet valve. This elevator will lift water 

 eighteen feet in high altitudes and thirty feet at sea 

 level, the difference being in the natural atmospheric 

 pressure. The elevator costs a few hundred dollars and 

 may be used in streams, wells, or reservoirs. 



The Bucket Elevator. This arrangement is cal- 

 culated to raise water from a stream by the force of the 

 current, but the writer does not accord to it all the great 

 things claimed by the inventor, Ira J. Paddock, of Hem- 

 ingford, Nebraska. The device is crudely sketched in 

 Figure 87. According to this plan, two upright posts 

 are to be driven a few rods apart on the farther bank of 

 the stream, and two or more on the nearer side, at least 

 one being far enough up the slope to be beyond the res- 

 ervoir. To the tops of the posts are fastened, by short 

 ropes, pulley blocks, through which is rove a taut endless 

 rope belt. This should be two feet above the ground, 

 and should run quite a distance lengthwise over the 

 stream ; the latter adjustment being effected by giving 

 enough length to the fastenings of the pulleys to the 

 two posts on the farther bank.
