page_text: TARVER'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
TARVER, of Daventry, in the County of Northampton, Iron Founder, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-first day of January (One thousand eight hundred
and forty-five), in the eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said James Tarver, my executors,.
administrators, and assigns, Her especial license, full power, sole privilege and
authority, that I, the said James Tarver, my executors, administrators, and
assigns, and such others as I, the said James Tarver, my executors, administra-.
tors, and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term of years therein expressed, should and·
lawfully might make, use, exercise, and vend, within that part of Her Majesty's
United Kingdom of Great Britain and Ireland called England, Her Dominion
of Wales, and Town of Berwick-upon-Tweed, in the Islands of Jersey, Guernsey,
Aldernay, Sark, and Man, and also in all Her Majesty's Colonies and Planta.
tions abroad, my Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
CUTTING, GRINDING, AND DRESSING VEGETABLE SUBSTANCES;" in which said Letters
Patent is contained a proviso, obliging me, the said James Tarver, by an
instrument in writing under my hand and seal, to particularly 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 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 thereto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Tarver, do hereby declare that the nature of my said Invention, and in

page_text: what manner the same is to be performed, is fully and accurately set forth in
and by the following description thereof, reference being had to the Drawings
hereunto annexed by the numeral figures and letters marked thereon for the
purpose of such reference, that is to say:
Figure 1 is a view, in upright side elevation, of the machine, in which the
parts shewn within the circle V, W, are shewn by making a section through
the machine on the dotted line X, Y, in the Figure 2. Figure 2 is a view of
the machine, as it is shewn in Figure I., taken in horizontal plan, and shewing
at X, Y, the section mentioned in Figure 1. Figure 3 is a view, in upright
end elevation, of the machine (as it is shewn in Figure I) taken on that end of
the machine on which the knives are fixed, and which end is marked....E....in
Figure 1. The several and corresponding parts of the machine are in each
of the Figures 1, 2, and 3 marked respectively with the same. letters of
reference, in as far as such several and corresponding parts can be seen in the
views of the machine depicted in such Figures respectively. In the several
Figures of the Drawing, A, A, marks the fly wheel of the machine; B, B,
mark rising rollers, the action of which is to propel or forward the straw or
substances on which the machine is required to act; C shows a helical screw
or worm, by which motion is given to the roller B, B3, through the gearing and
action of the helical screw or worm into and upon two face cog wheels M, M,
(seen in most distinctness in Figure 2); D marks a forked guage, by which
the action of the chaff-cutting knives L, L, is thrown off the machine or out.
of operation; this is done when the grinding apparatus or the mill R is to be
put in action.
E marks a lever bar, which carries at its lower extremity a
weight F, and is used to regulate the quantity of compression of the straw or
substance on which the machine is required to act; G marks a set screw, by
which the grinding mill R is adjusted and regulated, in order to suit its action to
the coarser or finer grains to be submitted to its operation; I marks a door or
opening, which affords convenient access to the grinding mill R for the purpose
of cleansing or clearing it of accidental obstructions; I (seen in Figures 2 and 3)
shews, a cranked lever, by which the operator who feeds the machine is enabled
to assist a second operator, who is employed in turning the fly wheel A, A, by
the handle T; K marks a crank, through which motion is transferred from
the lever I; L, L, mark the chaff-cutting knives, set upon the fly wheel A, A;
M, M, mark the two face cog wheels before mentioned, by which motion is
given to the rising rollers B, B; N marks a shifting spur wheel, set on the
shaft O, O, and which can be put into or out of gear with the spur wheel P
at pleasure for the purpose of throwing the grinding apparatus or mill R into
er out of action; 0, 0, marks the fly wheel shaft, and o, o, the spindle of the

page_text: grinding mill R; P marks the before-mentioned second wheel, set upon the
spindle o, o, of the mill R, and taking its motion by gearing with the
moveable wheel N; Q marks the hopper of the mill; R, R, marks the runner
or cutter of the mill; S is the feeding box or trough, by which the straw or
the substances to be operated upon by the knives L, L, are advanced to the
point of operation at the front of the machine; T marks the driving handle
of the fly wheel A, A; 1, 2, 3, 4, 5, 6 mark the set screws, by the adjustment
and action of which the knives L, L, aro regulated.
Having thus described the nature and intention of my said Invention, and
also in what manner the same is to be ascertained and performed, I now
declare that I claim as of my Invention the particular modes of arrangement,
and the particular combinations of parts, together with the principles of con-
struction upon and according to which such particular modes of arrangement
and such particular combinations of parts are made, and by which the same
are carried into practical effect, and I declare such the aforesaid circumstances
of modes of arrangement, combinations of parts, and principles of construction
to be in the manner, and, in fact, as I have herein-before specified, described,
and set them forth in this my said Specification and Drawings thereof.
In witness whereof, I, the said James Tarver, have hereunto set my hand
and seal, this Nineteenth day of July, in the year of our Lord One
thousand eight hundred and forty-five.
AND BE IT REMEMBERED, that on the Nineteenth day of July, in the
ninth year of the reign of Her Majesty Queen Victoria, the said James Tarver
came before our said Lady the Queen in Her Chancery, and acknowledged the
instrument aforesaid, and all and every thing therein contained and specified,
in form above written. And also the instrument aforesaid was stamped
according to the tenor of the Statute made in the fifty-fifth year of the reign
of Ilis late Majesty King George the Third.
Inrolled the Twenty-first day of July, One thousand eight hundred and
forty-five.
