Pulping 63 



unskilled labour, has to " experiment " with 

 his machinery, waste considerable time, and 

 even coffee, before he is able to get to the 

 proper adjustment of his machines. 



A new Improved Patent Coffee Pulper has 

 recently been introduced, the " Bon- Accord," 

 which simplifies a good deal the adjustment 

 mentioned above. The breast is self-adjusting 

 to the barrel. The adjusting screws on the 

 ears of the breast, and those on the side frames, 

 are done away with. The breast is simply put 

 in position and maintained there by means of 

 two hand wheels. The depth of the channels 

 on the breast is now all adjusted simultaneously 

 by means of an ingenious gear arrangement 

 and chains. The advantage of this simul- 

 taneous adjustment of the depth of the 

 channels is obvious, because as soon as one of 

 the channels is properly adjusted the others are 

 bound to be also. In the old system (still 

 adopted by some) of adjusting each channel 

 separately, it is practically impossible to adjust 

 two of the channels alike. I may also mention 

 that the above machine's new style of bearings, 

 or the cylinder's supports^ may also be con- 

 sidered as a great improvement from the 

 planter's point of view, since they last three 

 times as long as the previous style in use.
