CLXIII. In this quarter is presented to your view the Head of the Turning Engine, for the turning of Oval Work, Rose Work, and Swath Work, with other kind of Work not yet named, because not found out, for no Man hath yet sought out the depth of that Instrument, or what it can or is able to perform. It hath so many parts that I know not either how to describe or tell their use; only as in other Tools I shall give you what names each Member hath, if I be rightly informed.

The Moving Collar, is an Iron Collar fastned on a Center pin on the foreside of the Puppet; this moves between the Iron Shackle and the foreside of the Puppet; though properly the Collar is only the hole in which the Axis is set. The Neck of the Collar is that part under the Shackle.
