PROVISIONAL SPECIFICATION left by the said Christian Jurgenson at
the Office of the Commissioners of Patents, with his Petition, on
the 10th September 1873.
I, CHRISTIAN JURGENSON, of No. 4, Lombard Street, in the Town
and County of Newcastle-upon-Tyne, Merchant's Clerk, do hereby
declare the nature of the said Invention for "AN IMPROVED WEEDING AND
SEED GATHERING MACHINE," to be as follows:-
The machine consists of a drum supported on and geared to wheels in
such manner as to revolve by the revolution of the wheels, and pro-
vided with a set or sets of combs or knives working by means of an

page_text: eccentric slot or other similar gearing in and out of the drum as it
revolves, this movement of the combs or knives being also produced by
the revolution of the supporting wheels. The knives or combs are
intended to catch and cut off the seed buds of or to pull up by the roots
such weeds as raphanus sinapis, branica, camomile, and others growing
amongst young corn, or elsewhere. When it is desired to use the machine
as a seed gatherer a receptacle is

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Christian Jurgenson in the Great Seal Patent
Office on the 10th March 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHRISTIAN
JURGENSON, of No. 4, Lombard Street, in the Town and County of
Newcastle-upon-Tyne, Merchant's Clerk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of September, in the year
of our
Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Christian Jurgenson, Her special
license that I, the said Christian Jurgenson, my executors, administrators,
and assigns, or such others as I, the said Christian Jurgenson, 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
IMPROVED WEEDING AND SEED GATHERING MACHINE," a communication to me
from abroad by Andreas Ingermann, a person resident at Kolmaes,
Duchy of Schleswig, upon the condition (amongst others) that I, the said
Christian Jurgenson, my executors or administrators, 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.

page_text: NOW KNOW YE, that I, the said Christian Jurgenson, 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:—
The machine consists of a drum supported on and geared to wheels in
such manner as to revolve by the revolution of the wheels, and provided
with a set or sets of combs or knives working by means of an eccentric
slot or other similar gearing in and out of the drum as it revolves, this
movement of the combs or knives being also produced by the revolution
of the supporting wheels. The knives or combs are intended to catch
and cut off the seed buds of or to pull up by the roots such weeds as
raphanus sinapis, brassica, camomile, and others growing amongst young
corn or elsewhere. When it is desired to use the machine as a seed
gatherer a receptacle is attached so as to receive what falls from the
knives or combs.
The above-mentioned machine is shewn in the annexed Drawing in
plan, Figure 1 A, and in side elevation Figure 1 B. In 1 A part of the
outer covering of the drum is left out; in 1 B part of the wheels are
left out..
The principal details of the annexed Drawings are explained in the
following:-The work of the machine as a weed cutting machine is to
destroy the raphanus senapis and brassica, and other similar description
of injurious weeds, creepers, buttercups, and camomile, and flowering
plants which grow amongst young corn if the ground is soft; some of
these weeds are pulled out with the roots, in other cases they are merely
destroyed by cutting off the heads. The machine is also capable of
gathering many kinds of grass or clover seeds by stripping the seed
heads and depositing them in a bag which may be attached to the
machine for the purpose. The machine can be worked by hand or
otherwise. The size of the machine must be proportioned to the power
to be applied.
The machine consists of an iron drum No. 1, supported by two wheels
out of which three sets of iron or steel combs or knives, colored blue,
move alternately in and out, so that they clean themselves by scraping
past the sharp edges of the drum. The in and out movement of these
combs or knives is produced by the pin No. 3, which is guided by an
eccentric slot No. 4 which is fixed to the stationary ends of the drum

page_text: No. 5. The ends of the drum are also of iron and fixed to the wooden
frame No. 6, and are provided in the middle with round openings
through which the pins No. 7 are guided. At one end the small
pinion No. 8 is fixed which moves the drum No. 1 over the pin No. 7,
and through the end No. 5 a ferrule No. 9 is placed to which a piece of
iron is fastened angularly, and on which the axle No. 10 rests. Upon
these axles are placed two wheels like ordinary cart wheels, colored red,
which carry the machine, and of which one is made use of to drive the
drum.
Upon the axle No. 10 is a tooth segment No. 12 which is in con-
nection with two other small wheels No. 13, and serves to place the
drum in any desired position relatively to the ground which is to be
weeded, or from which seed is to be gathered. The small wheels No. 13
are placed upon a round spindle, at the end of which is a conical wheel
No. 14 which is in connection with a similar wheel fixed upon a spindle
leading to the crank No. 15. By the turning of this crank the drum is
raised or lowered. In front of the two wheels colored red are two wedge-
shaped iron guards, colored green, intended to push corn to one side out of
the way of the wheels, these guards are partly in connection with the
axles No. 10, and partly consist of an elongated arm which reaches to a
guiding bar No. 17, at the end of which is fixed a rack No. 19 intended
to regulate the relative position of the guards and drum. The guards
are lifted up or lowered in the same proportion as the axles. Inside of
the frame in the space No. 20 a frame with a bag can be placed to
gather up weeds or seeds. The iron fork No. 21 which is let into the
wooden framing prevents the ferrule No. 9 from falling out, and is in
connection with the crank attached to it. In the driving wheel No. 8 is
a stopper which can be taken out so as to permit the drum to stand still
when the machine is transported from place to place. The board No. 22
which is bound with iron and leans against the drum serves to lead the
seeds into the bao
Figures II. and III. in the Drawing shew a section through the drum
with the end plates and the eccentric slot No. 4 attached to it, but
without the sets of combs or knives before described. Figure IV. shows
the same parts with the combs or knives and the mode in which they 3
are fixed. These combs or knives are fixed at the circumference of the

page_text: rotating drum and are worked in and out by the pin No. 3 fixed to
them, and by the eccentric slot No. 4, Figure II.
What I claim is the construction of weeding and seed gathering
machines with a revolving drum supported on wheels, and provided with
combs or knives which are protruded and withdrawn, substantially as
described.
In witness whereof, I, the said Christian Jurgenson, have hereunto
set my hand and seal, this Sixth day of March, in the year of
our Lord One thousand eight hundred and seventy-four.
