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 Power Asparagus 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 end 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.
