AN INSTRUMENT OR SHEARS FOR PRUNING OF TREES, GATHERING GRAPES AND OTHER FRUIT, AND FOR CUTTING OPF SUCH LIMBS AS MAY BE INJURED, AND THEREBY MORE EASILY DESTROYING THE INSECTS OCCA- SIONED BY BLIGHTS, WHICH I DENOMINATE AN AVERRUNCATOR
Year: 1812

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
JUKES, of Walworth, in the County of Surrey, Gentleman, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date the Seventh day of November, in the fifty-
third year of His reign, give and grant unto me, the said Edward Jukes, my
exors, adñiors, and assigns, His especial licence, full power, sole privilege and
authority, that I, the said Edward Jukes, my exors, admors, and assigns,
should and lawfully might, during the term of years therein mentioned, make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "AN INSTRUMENT OR SHEARS FOR PRUNING OF
TREES, GATHERING GRAPES AND OTHER FRUIT, AND FOR CUTTING OPF SUCH LIMBS
AS MAY BE INJURED, AND THEREBY MORE EASILY DESTROYING THE INSECTS OCCA-
SIONED BY BLIGHTS, WHICH I DENOMINATE AN AVERRUNCATOR;" in which said
Letters Patent there is contained a proviso, that if I, the said Edward Jukes,
shall not particularly describe and ascertain 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, and cause the same to be inrolled in His Majesty's
High Court of Chancery within two calendar months next and immediately
after the date of the said Letters Patent, that then the said Letters Patent,
and all liberties and advantages whatsoever thereby granted, shall utterly
cease, determine, and become void, as in and by the sanie (relation being
thereunto had) may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Jukes, do hereby declare that the nature of my said Invention, and
the manner of performing the same, are particularly described and ascertained
in manner following, that is to say :---
In Figures 1, 2, and 3, and 3 and 4, of the Drawing in the margin hereof,
A, B, represents a staff of any convenient length, and capable, if preferred,
of being prolonged, by additional jointed parts or otherwise, towards A.
R, C, D, Fig. 1, represents a crook or piece so figured as that the hollowed
part d may be hooked over the branch or limb intended to be pruned or cut,
and on the other side C is an hole H to admit a center pin E, F, G.
Fig. 2 represents a steel blade or cutter having an edge at F, F, and an
arm or lever G, E, proceeding from G, by means of which the blade may be
moved upon an axis or pin or center at G, which, when in use, is passed thro'
and secured in the hole H, Fig. 1, and the whole instrument then appears as
shewn in Fig. 3. From E proceeds a string or catgut thro' a slit on the pole,
and over a pulley at I, whence it proceeds downwards, and when pulled serves
to depress the extremity E, and raise the blade F, which, being flat on the
side next to the piece C, D, and moving against a projecting or raised part of
the face of C, D, nearest the hollow part d, docs serve in the manner of sheers,
(altho' the whole operation of cutting off the limb or branch intended to be
pruned or lopped is effected by the edge F, F,) whilst the raised bolster or
opposing part of the crook d resists the pressure of the edge F, F, when
cutting through the limb so intended to be pruned or lopped. L is a spring
for raising the lever G, E, and consequently drawing back the edge after
making the cut, and by that means leaving the opening d ready for a second
operation. K is a stud or piece for suspending a basket to receive fruit when
the averruncator is used for cutting grapes or any other description of fruit.
And lastly, I do declare that, in the use of the said averruncator, the blade
should be placed or turned nearest the trunk of the tree, in order that the
cut may be close and clean, and the parts not cut off may not be bruised or
otherwise injured, and that I usually make the part R, C, D, of brass; but
with respect to the materials and dimensions of the whole instrument, and of
the several parts thereof, the same may be varied, and also, to a certain extent,
the forms thereof, according to the nature of the work intended to be per-
formed, and the choice of the persons intending to use the same; and one of
these variations, which makes the instrument very compact and convenient,
are shewn in Fig. 3 and 4. In these Figures the same letters of reference
are used to denote the same parts, except the following, in which the alter-
ations consist, viz-At the end of the arm G, E, a mortise or opening is

page_text: made to admit a small pulley S, and the pulley I is brought up nearer to the
top of the staff; the catgut or string T passes (as in the other method) over
the pulley I; but, instead of being fastened to the end of the lever E, it passes
round the pulley S, is made fast, going through the staff, and being knotted at
V. By this alteration the power of the instrument is increased by the addi-
tion of the sheave, or the lever E, G, may be made much shorter to obtain
the same purchase or power for cutting as by the former method.
In witness whereof, I, the said Edward Jukes, have hereunto set my
hand and seal, this Sixth day of January, in the year of our Lord One
thousand eight hundred and thirteen.
AND BE IT REMEMBERED, that on the Sixth day of January, in the
year of our Lord 1818, the aforesaid Edward Jukes came before our said
Lord the King in His Chancery, and acknowleged the Specification aforesaid,
and all and every thing therein contained and specified, in form above written.
And also the Specification aforesaid was stampt according to the tenor of the
Statute made for that purpose.
Inrolled the Sixth day of January, in the year of our Lord One thousand
eight hundred and thirteen.
