Im- PROVEMENTS IN MILLS FOR GRINDING
Year: 1848

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
ADAMS, of West Bromwich, in the County of Stafford, Organist, 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
November One thousand eight hundred and forty-eight, in the twelfth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Samuel Adams, my exors, adiñors, and assigns, Her especial
licence, full power, sole privilege and authority that I, the said Samuel
Adams, my exors, adiñors, and assigns, and such others as I, the said Samuel
Adams, my exors, adññiors, 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 "Im-
PROVEMENTS IN MILLS FOR GRINDING;" in which said Letters Patent is contained
a proviso, that I, the said Samuel Adams, should cause a particular descrip-
tion of the nature of my said Invention, and in what manner the same is to
be performed, by an instrument in writing under my hand and seal, to be
inrolled in Her said 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
Samuel Adams, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to

page_text: the Drawings hereunto annexed, and to the ngures and retters marked thereon,
that is to say -
My Invention consists of improvements in coffee, malt, and other metallic
mills for grinding. And in order that my Invention may be most fully
understood, and readily carried into effect, I will proceed to describe the
same:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an external view of a horizontal mill, having my improve-
ments applied thereto; Figure 2 shows a vertical section thereof, and Figure
3 is a plan with the upper cover, and what I call the shield removed, in order
to the interior parts being shown. The other Figures of the Drawings, which
are marked with the same letters of reference, show separate views of parts
of the mill. The conical cutters of this mill are shorter than those in
ordinary metallic mills, and the angles of the cutting surfaces are those. I
prefer for malt, but do not confine myself thereto. a is the fixed cutter, the
cutting surface of which I prefer to be of steel. This cutter a simply consists
of a plate, having a conical opening through it formed with teeth, such teetli
being formed in the ordinary manner. b is the moving cutter, having teeth
which I also prefer to be of steel, and this cutter is carried by, and is affixed
to the axis c, such axis having its bearings at d, d, and it is capable of being
set to its work with the cutter a by means of the set screw e. The cutter b
has a series of inclined planes, projections or surfaces f, the shape and size
of which may be varied; they tend to press the grain in between the angular
space formed by the coming together of the two cutters a and b. By the
application of these inclined planes, projections or surfaces, I find that a
larger quantity of work can be done by a mill, as they not only prevent the
grains or matters getting away from between the cutting edges of the mill,
but they also by their inclined character or position press the grain or matters
(to be ground) in between the angular space, where the grinding is performed.
On the axis c is fixed a bevilled, toothed wheel g, which takes into and. is
driven by the bevilled toothed wheel h, on the main axis i, as is. shown. On
the axis i are fixed the fly wheel j, and a winch handle to give motion to the
axis. k is a shield to relieve the upper side of the moving cutter from the
pressure of the grain or matter to be ground, thus reducing the friction wher
working; the shield also guides the grain or matter directly into the space
between the cutters a, b, and the shield also covers and protects the wheels
g, h; is the cover of the mill suitably formed for receiving a hopper .
My Invention is also applicable to vertical mills, and Figure 4 shews an
edge view, and Figure 5, a side view of a vertical mill, having my improve

page_text: ments applied thereto, and Figures 6 and 7 show two vertical sections of the
same mill. ais the fixed cutter, which, like that in the preceding mill, consists
of a plate, having a conical opening through it with teeth or cutting surfaces
formed thereon, as in other metallic mills; b is the moveable cutter, and k is
a shield to keep the grain or matter to be ground from coming in contact
with the end of the moving cutter b, the objects of which are to lessen the
friction in the working of the mill, and thus keep the grain from heating, and
also for directing the grain in between the cutting parts of the mill. In this
mill I also apply inclined planes, projections or surfaces f, f, for the purposes
of preventing the grain getting away from the cutters, and for forcing the
grain or matters in between the cutters a, b.
The Drawing clearly shows the nature of each of the parts; the moveable
cutter is fixed on the main shaft or axis i, which has also the fly wheel j. and
winch handle fixed thereon.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would state that I do not confine myself
to the details as herein described, so long as the peculiar character of either
part of my Invention be retained; but what I claim is,―
First, the application of a shield k, as herein described.
And secondly, I claim the application of inclined projections, surfaces, or
planes f, f, and the manner of constructing and combining the cutters a, b.
n witness whereof, I, the said Samuel Adams, have hereunto set my
hand and seal, this Fifteenth day of May, in the year of our Lord
One thousand eight bundood and Lamber
AND BE IT REMEMBERED, that on the Sixteenth day of May, in the
year of our Lord 1849, the aforesaid Samuel Adams 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 Sixteenth day of May, in the year of our Lord One
thousand eight hundred and forty-nine.
