Experience has proven dial this number of speed. The ea ily be removed by withdrawing the pins which hold It in place, and ■< quick!] ob tained by removing the trips Bcrewed to the back of thiHoller. Another Importanl feature which assures the adaptabilityof these control lei to various conditions la the racl thai thehandle and ratchel are bo designed thai they may be removedfrom the controller and placed a1 any point which is con-venient, permitting connection to the controller by meansni bevel gears and Bbafting. This not only adapts theapparatus tor distant control, bui it enables the operator touse the same handle, ratchel and Indicator dial which are furDished with the controller; ihis saves the expense ol makinga new handle and ratchet, as is necessary In some ca Tho notches In th< ratchel are pc Itive, and the designBuch that as each step i reached a key drops into a notch andstops the handle, holding it firmly in place until released by alire upon the thumb Btop in the end of the ha
