IMPROVEMENTS ON HARROWS
Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ARMSTRONG, of Hawnes, near Ampthill, in the County of Bedford, Farmer,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Thirtieth day of May, in the second year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said William
Armstrong, Her especial licence, full power, sole privilege and authority, that
I, the said William Armstrong, my exors, adiñors, and assigns, or such others
as I, the said William Armstrong, my exors, admors, 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, ex-
ercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "IMPROVEMENTS ON HARROWS;" in which said Letters
Patent is contained a proviso that I, the said William Armstrong, shall cause
a particular description of the nature of my said Invention, and in what
manner the same is to be performed, 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 Patents, 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
William Armstrong, do hereby. declare the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and

page_text: ascertained in and by the following statement thereof, reference being there-
unto had to the Drawing hereunto annexed, and to the figures and letters
marked thereon (that is to say) :-
According to the ordinary construction of harrows, the bars or beams com-
posing the framing into which the tines or teeth are affixed consist of straight
bars from end to end of the harrows. Now the object of the first part of my
Invention is, to construct harrows with bars, which are of a zigzag figure, by
which I am enabled to apply the tines or teeth more advantageously than when
affixing them in straight bars one behind the other.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a set of harrows, each arranged according to this part
of my Invention. The three harrows cover a space of about ten feet wide.
a, a, are the zigzag bars, having a tine or tooth at each angle formed by the
bar. These bars may be either of wood or iron, as is usual in constructing
harrows. I would remark, that I do not confine myself to any particular
dimensions of harrows, nor to the number of bends or angles of which each
bar a is composed; but the same may be varied.
Figures 2, 3, and 4 show variations of the same mode of constructing
harrows, differing only as to the order of the bends or angles of which the
bars a are composed.
Another part of my Invention relates to the mode of obtaining the draught
to harrows. c, c, are the ordinary hooks or points of draught, one to each
harrow; and b, b, are additional hooks, or such like instruments, for con-
necting the harrows to the means of draught or draught beam, such additional
hooks or means of connection being at each end of the harrows. And I
would remark, that if in any particular cases more play is required, in such
case the hooks b would not for the time being be used, but the hooks c,
the improvement being the using of the additional attachments b, on on each
side of the centre.
Another part
of my
Invention relates to the application of the braces d, d,
or, in place of the braces, the guide shown in dotted lines, for connecting the
draught beam with the horses or other animals.
In witness whereof, I, the said William Armstrong, have hereunto set
my hand and seal, this Twenty-ninth day of November, in the year of
our Lord One thousand eight hundred and thirty-nine.
WILLIAM (L.s.) ARMSTRONG.
