The proper posi-tion of the handle H for the proper meshing of pinion P withany one of the gears on the cone is easily determined by thenumbered index and the locking holes at E, as shown in ; the hanu^e h neecis only to be brought under the numbercorresponding to the cone gear desired and its pull-pin droppedinto the locking hole below that number.
