CERTAIN IMPROVEMENTS IN MILLS FOR GRINDING WHEAT AND OTHER GRAIN
Year: 1849

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GOODIER, of Mode Wheel Mills, near Manchester, in the County of Lancaster,
Miller, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Ninth day of July, in the thirteenth year of Her reign, and in
the year of our Lord One thousand eight hundred and forty-nine, did, for
Herself, Her heirs and successors, give and grant unto me, the said John
Goodier, Her especial license, full power, sole privilege and authority, that I,
the said John Goodier, my exors, adñiors, and assigns, and such others as I;
the said John Goodier, my exors, adiñiors, and assigns, should at any time agree
with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise, .
and vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "CERTAIN IMPROVEMENTS IN MILLS FOR GRINDING WHEAT AND OTHER
GRAIN;" in which said Letters Patent is contained a proviso that I, the said
John Goodier, shall cause a particular description of the nature of my said:
Invention, and in what manner the same is to be performed, to be enrolled

page_text: in Her Majesty's High Court of Chancery within six calendar months next.
and immediately after the date of the said in part recited Letters Patent, as
in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Goodier, do hereby declare that the nature of the said Invention, and
the manner in which the same is to be performed, is particularly described
and ascertained in and by the Drawings hereto annexed, and the following
explanation thereof, that is to say:-
These Improvements in Mills for Grinding Wheat and other Grain
relate,
Firstly, to an improved mode of balancing the upper stone or runner, so as
to avoid the rubbing of one stone against the other in the operation of
grinding, and thereby materially to lessen the friction which takes place in
the ordinary mode of mounting millstones.
And in order that my Invention may be more clearly understood, I have
attached to this my Specification one Sheet of Drawings which I will now
proceed to describe, premising, that in all the Figures similar letters of
reference denote the like parts of the machinery.
Fig. 1 is a top or horizontal view of a pair of millstones with my improve-
ments applied.
Fig. 2 is a section taken vertically through the stones in the line a, b, the
driving apparatus being shewn complete.
A
Fig. 3 is a similar section taken in the line c, d; and Fig. 4 is a top hori-
zontal view of the bed stone and balancing apparatus of the runner. The
bed stone of the ordinary construction is shewn at a, a, through which the
driving spindle b, mounted in the usual bushes, is passed; the upper part of
the driving spindle is formed as a conc, the extremity thereof being rounded
in order to carry the gimbles upon which the running stone is mounted.
socket c, c, is fitted loosely on the conical upper part of the driving spindle b,
but is caused to revolve therewith by means of a feather or key fitted
to the spindle, and projecting into a groove formed in the socket c;
on either side of the socket c arms d, d, project upwards, which arms
are connected by means of pins e, e, to projecting pieces extending from
a boss f, which boss rests by means of a recess formed therein upon the
upper extremity of the driving spindle ; pendant from the boss f are arms
9, 9, which arms are turned at right angles at their lower extremities, and fit.
into grooves formed in the under part of the running millstone h, h at i, i;

page_text: by these means, the driving spindle being put into motion by any convenient
agency, the- socket c is caused to revolve, carrying with it by means of the
connecting pins e, e, the boss f, and consequently the stone h, h. The pins e, e,
which connect the arms d, d, to the boss f, are fitted into sockets and retained
therein by means of keys, as shewn in the Drawing; the sockets, however, are
formed sufficiently large to allow the pins e, e, to play slightly therein, the effect
of which will be, that, as the runner by the means above described is caused to
revolve, it will rock slightly upon the rounded extremity of the driving
spindle b, and thereby avoid the friction which would take place if the stone
were firmly attached to the driving spindle. In order to keep the stones cool
during the operation of grinding I have found it desirable to cause a current
or currents of air to pass through the eye of the runner, which may be
effected in various ways; the means by which I prefer to effect this I will
now describe, the same effect, however, may be produced by means of fans
or blowers, none of which I claim as of my Invention, detached from my
other improvements. Upon the upper surface of the runner h, h, there
are attached two curved tubes or passages k, k, which diminish in area as they
extend towards the centre of the stone, and the extremities thereof extend
downwards through the eye of the runner, as shewn in the Drawing,
the effect of which will be that as the runner revolves, a current of air will
be caused to rush through each of the said passages, and making its exit
at the bottom thereof will be distributed over the surface of the stones and
effect the required cooling.
Having thus fully described and ascertained the nature of my said Invention,
I wish it to be understood that that which I claim as secured to me under the
above in part recited Letters Patent is the mode above described of balancing
the runner millstone so as to allow a slight oscillation during the action
of grinding; and in combination with the said mode of balancing the stone
I claim the application of a current or currents of air passed down the eye of
the runner, such current or currents of air being either conducted by the
agency of tubes revolving with the runner, or by means of fans or blowers
of any suitable construction, capable in such combination of effecting the
desired object.
In witness whereof, I, the said John Goodier, have hereunto set my hand
and seal, the Eighth day of January, in the year of our Lord One
JOHN (L.S.) GOODIER.

page_text: AND BE IT REMEMBERED, that on the Eighth day of January, in the
year of our Lord 1850, the aforesaid John Goodier came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
Enrolled the Ninth day of January, in the year of our Lord One
thousand eight hundred and fifty.
