The Cylinder
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.
