Year: 1849

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CAREY
MCCLELLAN, of Larch Mount, in the Liberties of the City of Londonderry,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Sixteenth day of
January, One thousand eight hundred and forty-nine, in the twelfth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Carey McClellan, my exors, adññors, and assigns, Her especial
license, full power, sole privilege and authority, that I, the said Carey
McClellan, my exors, admors, and assigns, and such others as I, the said Carey
McClellan, my exors, adñiors, or 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
"AN IMPROVED CORN MILL," in such manner as I, the said Carey M°Clellan,
my exors, adiñors, and assigns, should deem expedient; in which said Letters
Patent is contained a proviso obliging me, the said Carey McClellan, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same is
to be performed, and to cause the same to be enrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately

page_text: 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
Carey McClellan, do hereby declare the nature of my said Invention to
consist,―-
First, in an improved mode of introducing or forcing air between the stones
of certain corn mills, for keeping the said stones and the flour produced between
them in a cool state while the mill is in operation. And,
Secondly, in doing away with the ordinary hopper, and applying a part of
the air pipe through which I force the air as aforesaid to the purpose of
feeding the said corn mills.
And in further compliance with the said proviso, I, the said Carey
McClellan, do hereby describe the manner in which my said Invention is to be
performed by the following statement thereof, reference being had to the
Drawing annexed, and to the figures and letters marked thereon, it being
observed that similar letters are used to denote similar parts in all the
And first, of my improved mode of forcing air
veen the stones.
Figure 1 represents a vertical transverse section of the principal parts of an
ordinary corn mill, grinding by an ordinary pair of stones driven in the usual
way. A is the bed stone, and B the running stone, J being the hopper now
generally in use for feeding the stones. C is the dainsel, which I make
hollow, and furnish with four or any other convenient number of hollow arms
marked H. These arms, it will be seen, radiate from the damsel in a direction
towards the circumference of the eye of the running stone, which, it will be
seen, is rounded at G, G, the better to direct the escaping air under it; to which
rounding, however, I make no claim as part of my Invention, as I am aware
it has been done before. D is a pipe or nozzle fitted on to the top of the
damsel in such manner as to allow of the damsel revolving freely below it.
This nozzle is furnished with a valve E for regulating the supply of air to the
millstones from the air pipe above it, marked F, through which pipe a
continuous current of air is blown by an ordinary fan or any other suitable
blowing apparatus. Now the result of this arrangement of the machinery of
the mill will be, that when the stones and damsel are set in motion, and a
current of air blown through the pipe F, the air will be distributed by means
of the branch pipes marked H with considerable force between the grinding
surfaces of the stones, thus keeping both the stones, and the corn and meal or

page_text: flour, in a cooler state while the operation of grinding is proceeding than can
be effected by any machinery now in use.
Figure 2 is an elevation of the hollow damsel C and nozzle D, separated
from the rest of the mill, and drawn to a larger scale, shewing more distinctly
three of my four-branch pipes marked H; Figure 3 is a sectional elevation
of the same, and Figure 4 is a plan thereof. Figure 5 is a sectional plan,
showing the details of the air-regulating valve; Figure 6 is a plan taken on
the line W, X.; and Figure 7 is a plan taken on the line Y, Z.
And now, secondly, of my improved mode of feeding the mill, which I do
through the damsel.
Figure 8 shews the manner in which I fix an ordinary pipe and cup feeder
to my damsel, without interfering with my arrangement for forcing air between
the stones. In this case, instead of the nozzle D being placed immediately
on the top of the revolving head of the damsel it is placed on one branch L
of a biforked tube K, L, which is stationary, the head of the damsel revolving
considerably below it at M. The stem which supports the cup N rises into
the branch K of the biforked tube, and O is the ordinary feed pipe adjusted to
deliver the quantity required into the cup by the regulator P. Figure 9 is
merely an enlarged view of the principal parts shewn at Figure 8.
And now, having fully described the nature of my Invention, and the manner
in which the same is to be performed, I hereby claim,-
First, my improved mode of forcing and directing air by means of a blowing
apparatus, driving it into branch radiating and revolving pipes, which pipes
distribute the said air between the stones or grinding surfaces of corn mills, as
herein-before described. And,
Secondly, my improved mode of arranging the ordinary pipe and cup-
feeding apparatus, so as to use it in combination with my improved mode of
forcing and directing the air, as herein-before described, whereby I am enabled
to throw the matter to be ground more directly between the said stones or
grinding surfaces, inasmuch as by this arrangement it follows the course of
the air through the radiating arms.
And such my Invention being, to the best of my knowledge and belief,
entirely new, and never before used within that part of Her said Majesty's
United Kingdom of Great Britain and Ireland, Her Dominion of Wales, and
Town of Berwick-upon-Tweed, I do hereby declare this to be my Specification
of the same, and that I do verily believe this my said Specification doth
comply in all respects, fully and without reserve or disguise, with the proviso
in the said herein-before in part recited Letters Patent contained. Wherefore
