[Illustration: Fig. IX.]
Fig. IX. represents the cylinder, with the lantern for turning the same
by means of the catches. The dimensions for the cylinder in the present
machine are as follows:
Height of cylinder, = 2-7/16 inches.
Width " " = 13 "
" " lantern, = 1-1/2 "
Average length of spindle, = 2 "
This cylinder is carried in the batten, the latter moving in the
groove provided for it under 10, Fig. I. This batten has sufficient
vibratory motion to enable it to move the required distance away from
the needle-board. After coming in contact with the catch it still moves
until the cylinder has performed a complete turn. The cylinder is
steadied in the required position by the hammer pressing by the means
of a spring towards the lantern from below.
