Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
BONSER, of Merton, in County of Surrey, Farmer, and EDWIN WATKINS
WILLIAM WYNN PETTITT, of York Road, Lamiseth, in the County of Surrey,
Engineer, send giceting.
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 Fifteenth day of July, in the tenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Bonser and Edwin Watkins William Wynn Pettitt, our exors,
adñiors, and assigns, 1er especial licence, full power, sole privilege and
authority, that we, the said Thomas Bonser and Edwin Watkins William
Wynn Pettitt, our exois, adiñois, and assigns, or such others as we, the said
Thomas Bonse and Edwin Watkins William Wynn Pettitt, our exois,
adiiors, and assigns, should at any time agice 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, and also in the Islands of Guernsey,
Jersey, Alderney, Sark, and Man, and in all Her said Majesty's Colonies and
Plantation abroad, our Jnvention of "CERTAIN IMPROVEMENTS IN MACHINERY
FOR TILLING LAND;" in which said Letters Patent is contained a proviso that
we, the said Thomas Bonsel, and Edwin Watkins William Wynn Pettitt, or
one of us, should cause a particular description of the nature of our said
Invention, and in what manner the same is to be performed, to be inrolled in

page_text: 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
largo appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Thomas Bonsel and Edwin Watkins William Wynn Pettitt, hereby declare
that the nature of the said Invention, and in what manner the same is to be
performed, are fully described in and by the present Specification thereof,
reference being had to the Drawings hereunto annexed, that is to say -
Our improvements in machinery for tilling land consist in employing for the
purpose a tiller, formed of a cylindrical shaft or drum, having a number of
radial cutters, or piongs, or tines, either straight or curved, attached thereto at
right angles, and arranged round it spiral-wise so as to present the appearance
of a screw, and, in combination therewith, the mechanical auxiliaries neces-
sary for causing the same to penetrate the soil; and the Drawings hereunto
annexed represent several exemplifications of the manner in which the said
improvements are called out.
In Figure 1 the radial cutters A, A, are employed, which are each sections
of a screw, and are attached edgewise to the cylindrical shaft on drum, so as to
be at every part of their outer edges at right angles with the axis of the shaft
oi drum.
In Figure 2, four blades B, B, are wound continuously round the cylindrical
shaft or drum, so as to form an entire screw.
In Figure 8 four 10ws of straight prongs or tines, of the shape represented
separately in Figure a, are affixed in spiral ducctions to the cylindrical shaft
oi dium, in place of which there may be substituted prongs or tines of either
of the forms represented in Figures b and c, or cutters of the form shewn in
Figure d, or prongs, or tunes, or cutters of any other suitable forms
Figure 4 is a side elevation of a tilling machme adapted to the working of
tilleis, such as before exemplified, D is a framework to which a horse or other
ammal may be harnessed, or any other suitable motive agent applied, E is a
roller, or one of a pan of wheels, which has its bearings in the framework D,
F is a cog wheel attached to one end of the axis of the wheels or 1oller E,
which cog wheel takes into another G, which works a pinion II, affixed to the
end of the axis of the tiller A, which has its bearings at the tail of the
machine, as shewn both in Figure 1 and Figure 4 The tiller, it will be
observed, is applied to the ground crosswise, and as it is made to revolve and
advance by the rotation of the wheel E, and the intermediate gearing F, G,
and II, and the application of suitable motive power thereto, the cutters, or

page_text: prongs, or tines, not only penetrate, divide, break up and crush the soil most
effectually, but serve to cut and eradicate any weeds or roots with which it
may happen to be encumbered.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that what we claim is the
employment in the tilling of land of tillers, consisting of cutters, oi piongs, or
tines, either straight or cui ved, attached at right angles to cylindrical shafts or
drums, and anlanged spiral-wise round the same, but without limiting ourselves
in any way as to the number of such cutters, or prongs. oi tines, and combined
with suitable wheel-work for giving a rotary and progressive motion to the
same, as before described,
In witness whereof, I, the said Edwin Watkins William Wynn Pettitt,
on behalf of the said Thomas Bonser and myself, have hereunto set
my hand and seal, this Fifteenth day of January, in the year of our
Lord One thousand eight hundred and forty-seven.
EDWIN WATKIN WILLIAM WYNN (L.s.) PETTITT
AND BE IT REMEMBERED, that on the Fifteenth day of January, in
the yea of our Lord 1847, the aforesaid Edwin Watkins William Wynn
Pettitt, 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 witten. And also the Specification
aforesaid was stamped according to the tenor of the Statute made for that
purpose.
Enrolled the Fifteenth day of January, in the year of our Lord One
thousand eight hundred and forty-seven.
