Year: 1865

page_text: LETTERS PATENT to Richard Smith, junior, of Unity Flour Mills, Belper,
in the County of Derby, for the Invention of "IMPROVEMENTS IN MOUNTING
AND DRIVING MILLSTONES."
Sealed the 27th April 1866, and dated the 3rd November 1865.
PROVISIONAL SPECIFICATION left by the said Richard Smith at the
Office of the Commissioners of Patents, with his Petition, on the 3rd
November 1865.
I, RICHARD SMITH, junior, of Unity Flour Mills, Belper, in the County of
Derby, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MOUNTING AND DRIVING MILLSTONES," to be as follows:-
This Invention has for its object improvements in mounting and driving
millstones. For these purposes the millstone which is caused to rotate is fixed
to the shaft and has simply a revolving motion communicated thereto, whilst
the other millstone has no rotatory motion communicated to it, but it is hung
or mounted on an universal joint or gimbles, so that it may be capable of
horizontal motion during the working or rotating of the other millstone, which,
as above stated, is fixed to and revolves with the shaft without the interposition
of an universal joint or gimbles.

page_text: It is preferred that the under millstone should be the one fixed to the shaft,
and that the upper millstone should be the one hung on a universal joint or
gimbles, but this is not essential.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Smith in the Great Seal Patent Office on the
3rd May 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
SMITH, junior, of Unity Flour Mills, Belper, in the County of Derby, send
