THE CYLINDER.

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 of cylinder,	=	13	inches.
Width of lantern,	=	1-1/2	inches.
Average length of spindle,	=	2	inches.

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.
