New YorK AGRICULTURAL EXPERIMENT STATION. 165 
in diameter was used. This is nearly twice as heavy as required. 
The use of a sprocket wheel on-the right rear wheel larger than 
that used on the Downs PowerAsparagus Sprayer,and swinging 
a shaft, 1 in. in diameter, over the right-hand side-plate, would 
allow a smaller sprocket wheel on the outer end of the shaft, 
also a smaller one on the inner énd next to the pump. In fact 
the latter could be small enough to be placed directly under the 
small sprocket-wheel on crank-shaft. In this way the pump 
could be placed nearer the tank, shorter chains could be used, 
and thus the weight of all the shafting and gearing be reduced 
nearly two-thirds. 
The weight could be reduced slightly by placing the elbow, 
which follows the safety-valve, next the T and placing the 
safety-valve beyond the elbow. |
