CLII. There are several sorts of fashioned Collars, of which these two in this quarter are apart. The first on the dexter side is termed a Round Collar, so called from the roundness of the head of it, it is to be fastned in a Lathe by a Wedge as the Puppets are under the Cheeks; Hollow Mandrels are often turned in the Collars of this form, but then the Spindle is made of Iron, and hath a Screw just at its end, upon which is screwed a Block with a hollow in it, made fit to receive the Stuff to be worked upon.
The second in this quarter hath the simple name of a Collar, without any other Addition, except you call it a Turners Collar, to distinguish it from other things termed Collars. It is also made fast in a Lathe by a Wedge, as the former is to be.
CLIII. This is termed by Turners, a Joynt Collar which is made of two Iron Cheeks, which move upon a Joynt with a Button, so that they may be set close or open, like a Joynt rule; on the inner edge of each Cheek is formed as many semi-circles or half round holes as the length of the Cheeks will conveniently bear, they are made of different Diameters that they may fit the necks or shanks of different sized Mandrels. Near to the top of one of these Cheeks is fastned with a center pin, a square Iron Collar with a small handle or button to it, which is to put it on and take it off the Cheeks when they are to be opened. This holds them so fast together that they cannot start asunder, and yet is made so fit that it may easily slip off and on. In this Instrument there are these parts.
- The Cheeks,
- The Joynt at the bottom.
- The Semi-circles in the Cheeks.
- The Diameters, circumferences or round holes in which the Cheeks are closed.
- The square Collar that holds the Cheeks together.
- The Handle, by which the said Collar is taken off or put on.
- The Center pin, on which the square Collar turns.
