TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of November, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Robert Sellar, Her special licence that I, the said Robert
Sellar, my executors, administrators, and assigns, or such others as I, the
said Robert Sellar, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVEMENT IN THE CONSTRUCTION OF HARROWS," upon the condition
(amongst others) that I, the said Robert Sellar, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Robert Sellar, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say :-
This improvement consists in a novel mode of constructing and fixing the
teeth or tines of harrows. Near the upper part of the tine there is a hole for
the reception of a horizontal bolt, by which the tine is affixed to the beam.
The upper part of the tine terminates in a screwed stem, which passes up
vertically through the cross bar, and is secured in its place by a nut. By
this means the tines are firmly affixed to and hold together the beams and
cross bars of the harrow.
And in order that the manner of performing my said Invention may be
clearly understood, reference is had to the annexed Drawings and to the

page_text: following description thereof; the same letters referring to similar parts in
each of these Drawings.
Figure 1 is a side view of one of the tines of a harrow detached; A is the
body of the tine, having an enlargement with a hole through it at B; c is a
screwed stem on its upper end; Figure 2 is an edge view; Figure 3 a front
view; Figure 4 a back view, and Figure 5 a perspective view, of the tine
affixed to the cross bar and beam of the harrow. D is the beam, and E the
cross bar of the harrow; f is a screw bolt and ƒf a nut by which the tine is
affixed to the beam D, the screwed stem c is then passed up through the cross
bar E and secured by a nut g, when the cross bar, beam, and tine will be held
securely together. Instead of using the nut fs the tine may be tapped
and the bolt screwed into it, but I prefer to use the former arrangement.
In witness whereof, I, the said Robert Sellar, have hereunto set my
hand and seal, this Twentieth day of February, in the year of our
Lord One thousand eight hundred and sixty-four.
Witness,
W. BADDELEY,
Patent Agent,
Islington.
