THE SURFACE SPIRAL. 194 This comparatively simple arrangement works perfectly, and is now fitted to the lathes of many amateurs ; it is less trouble to mount, and relieves the spiral apparatus of the inherent loss of … time derived from the extra wheels; and further, the work pro¬ duced by the different trains of wheels employed upon cylinders, may be transferred to the surface, without differing in any way by the introduction of extra gearing.
