spindle. The bowl is turned up true and perfectly balanced, so 
that there is no vibration arising from its own motion. Should 
there be any irregularity of the speed of the spindle, the mo-

spindle, and to maintain practically a uniform velocity. The

the vertical spindle in two lengths, the upper length which was 
attached to the bowl bearing on a toe step of cork formed in a 
socket on the lower part of the spindle. Some such com- 
pensating arrangement is certainly a " desideratum " either for 
hand machines — where the operator does not work quite uni- 
formly — or, as already stated, where machines are driven by horse 
works.
