WHEREAS le present most xcellent Majesty Queen Victoria,
11e Royal Letters Patent under the Great Seal of Great Butai,
beaug date at Westminster, the Sixth day of June in the minth
of Hei eigu, did, for Heiselt, Her hens and successors give and giant
unto me, the said John Tavlor, my executors, administrators and assigns,
Her especial licence, full power, sole privilege and authouty that I, the
sand John Taylor, my executors administrators. and assigns, on such
others as I, the sand John Tavlor, my executors administrators, or
assigns. should at any time agice with, and no others, from time to
time and at all times duing 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 FLOUR MILLS." In wluch said Letters Patent
15 contamed a proviso. that I the said John Taylor, shall cause a
particular desciption of the nature of my said Invention, and in what
manner the same is to be performed, to be molled in lei said
Majesty's High Court of Chancery within six calendar months next
and immediately after the date of the said m part recited Letters

more fully and at-large-appeal.
NOW KNOW YE, that in compliance with the said proviso, I, the
sand John Taylor, hereby declare that the nature of the sand Invention,
and in what manner the same is to be performed, are fully described m
and by the present Specification thereof, reference being had to the
Diawings hereunto annexed, that is to say
-
My said Invention consists, firstly, in certam improved methods of
introducing an between the stones of flour mills I make a continuous
opening A. A, though and through the upper of the two stones usually
employed in such mills, and camed m a curvilinear duection round the
eye B of the stone, as represented by the red line in Figures 1 and 2
of the Drawings so that it shall exhilat the form of curve known as the
volute, or as nearly so as may be sufficient for all practical purposes
O, instead of one continuous opening of the volute form, I make a
number of holes i tlie storie, placed in such-positions that if a con-
tinuous line were diawn though their centies it would describe a
volute The width of the openings and size of the holes when sub-
stituted for the continuous opening will vary with the nature of the
substances to be ground, such as wheat, bailey, oats, Indian cor,
&c, &c. At different points in the continuous opening as a a, a. or on
the top of each hole when holes are substituted, a deflecting cap C, is
fixed, and bent over in the duection of the line of motion so as to catch
the an.
'The ai thus deflected down between the stones combmes with
the draft though the eye B, to produce what may be called a system of
self-acting ventilation which prevents the stones from heating. By this
aueans also the mull stones can be kept with more face, and not only
make better work, but grind from ten to fifteen per cent more with
the same power than such mill stones as are in common use I wish
it to be particularly understood that what I clam as the peculiar and
distinctive feature of this part of my Invention is, the making the opening
in the upper mill stone of the form of a continuous volute, or nearly so, o
placing the holes substituted for such continuous volute (whatever may
be the size o number of such openings) in such positions that a hne
drawn through their centies would describe a continuous volute, and sur-

page_text: mounting the said opening or openings with deflecting caps hent over
in the duection of the Ime of motion 1 do not give any definite
proportions for such openings, as they will require to be varied as before
stated, according to the nature of the substances to be ground A
third mode of introducing an between the stones of flour mills, founded
on the same principle as the preceding. is represented in Figures
3 and 4 Figure 3 being A plan and Figure 4 a section through the
centre of the same A, A is the upper mill stone, B, B, B, B. a series
of funnel-shaped openings which project upwards a little way above the
upper surface of the stone and are attached to the ends of a corre-
sponding series of pipes C, C, C which lead through the interior of
the stone towards the cyc E These pipes may be either flat. as
represented or round, or of any other convement form. and their
funnel-shaped mouths are placed in such positions that a line diawn
though then centes, as indicated by the red colored line, would
descube a volute as in the plans first before described
The pipes
C, C C C e themselves also caned in a curvilinear direction from
then mouths towards the eye of the stone, and are passed down the
eye (still preserving the same curvilinear ducction as much as is con-
veniently practicable) until they reach within a little of the lower side
of the mill stone A A where they terminate in outlets D, bent back-
wards in the dnection of the outer edge of the stone
By the anange-
ment just described the an is caught by the funnel-shaped mouths
B, B, of the pipes (in the same way as in the two proceeding plans),
and by the rapid revolution of the stone it is made to pass along the
pipes C, C by which it is conveyed between the mill stones and thereby
prevents either the heating of the stones on the deterioration of the
floui
My Invention consists. secondly, of a peculiar mode of introducing
an into the cylinders used in diessing flour, represented in Figures
5 & 6 of the Diawings hereunto annexed The an is introduced or
conducted by an aperture D, into the cylinders This aperture is
placed or constructed near that part of the hopper termed 'the shoe,"
which introduces the flour into the cylinders, so that a complete
admixture of the air with the flour takes place as they enter the cylinder

page_text: together, as shewn in the Drawing I do not assign any particular
proportions for this aperture, as these also must vary with the size of
the cylinders and the modes of then construction Both Inventions
may be applied to mill stones and diessing cylinders which are at
present in use, as well as to such as may be expressly constructed with
a view to their adoption.
In witness whereof. I. the said John Taylor, have hereunto set
my hand and seal, this Second day of December, in the year of
our Lord One thousand eight hundred and forty-six
