Year: 1858

page_text: LETTERS PATENT to Edward Green, of Wakefield, in the County of York,
Engineer, for the Invention of "IMPROVEMENTS IN IMPLEMENTS FOR HARROW-
ING. PULVERIZING CLEANING AND BREAKING UP LAND"
PROVISIONAL SPECIFICATION left by the said Edward Green, at the
Office of the Commissioners of Patents, with his Petition, on the 14th
April 1858.
I, EDWARD GREEN, of Wakefield, in the County of York, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
IMPLEMENTS FOR HARROWING, PULVERIZING, CLEANING, AND BREAKING UP LAND,"
to be as follows:-
My Invention consists in certain arrangements of spike rollers, which are
set or fixed at angles with the line of the draft of the implément. When two
rollers are used they will be in the form of a cone; these rollers have a number
of spikes, teeth, or blades fastened to their outer circumference, divided into.
spaces along their whole length.
These spikes are intended to act as harrows, pulverizers, or scarifiers for
cleaning and breaking up the land. The rollers will be allowed to revolve,
either continuously or at intervals, so as to rid them of earth or weeds. When
mounted on wheels with levers, &c., the rollers can be raised and lowered as
circumstances may require.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
GREEN, of Wakefield, in the County of York, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Edward Green, Her special licence that I, the said Edward Green,
my executors, administrators, and assigns, or such others as I, the said
Edward Green, 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 "IMPROVEMENTS IN
IMPLEMENTS FOR HARROWING, PULVERIZING, CLEANING, AND BREAKING UP LAND,"
upon the condition (amongst others) that I, the said Edward Green, 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.
NOW KNOW YE, that I, the said Edward Green, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawing hereunto annexed,
that is to say:-
My Invention consists in certain arrangements of spike rollers, which are
set or fixed at angles with the line of the draft of the implement. When two
rollers are used they will lie with their axes inclined at an angle to each other.
These rollers have a number of spikes, teeth, or blades fastened to their outer
circumference, divided into spaces along their whole length. These spikes
are intended to act as harrows, pulverizers, or scarifiers for cleaning and
breaking up the land. The rollers will be allowed to revolve either con-
tinuously or at intervals, so as to rid them of the earth or weeds. When

page_text: mounted on wheels with levers, etc., the rollers can be raised and lowered as
circumstances may require.
In the Drawing hereunto annexed, I have represented in plan view an
implement constructed according to my Invention. A, A, are the inclined
rollers furnished with spikes, teeth, or blades a, a; B is a hand wheel con-
nected with an arrangement of rods and mitre wheels for elevating and lowering
the rollers; C are levers for the same purpose; D, D, are the running wheels of
the machine. The construction of the frame of the machine and the manner
in which it is combined with the several parts are evident on inspection of the
Drawing.
And having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I do not confine myself to
the details described and represented, but I claim the construction of imple-
ments for harrowing, pulverizing, cleaning, and breaking up land with rollers
furnished with spikes, teeth, or blades, and fixed at any suitable angle or
angles with the lines of draft of the implements, and with each other, where
there are two.
In witness whereof, I, the said Edward Green, have hereunto set my
hand and seal, this Twelfth day of October, One thousand eight
hundred and fifty-eight.
