Year: 1857

page_text: LETTERS PATENT to George William Robinson, of Barton-on-Humber,
for the Invention of "IMPROVEMENTS IN CLOD-CRUSHING ROLLERS."
Sealed the 23rd March 1858, and dated the 29th October 1857.
PROVISIONAL SPECIFICATION left by the said George William Robinson
at the Office of the Commissioners of Patents, with his Petition, on the
29th October 1857.
I, GEORGE WILLIAM ROBINSON, of Barton-on-Humber, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN CLOD-CRUSHING ROLLERS,"
to be as follows:-
This Invention has for its object improvements in clod-crushing rollers.
For these purposes each roller is composed of numerous sections or rings as
heretofore, but in the construction of a roller according to these improvements
the periphery of each ring is made with spikes or projecting points, the two
outer sides of each of which are made to a curved form consisting of about
a quarter of a circle; the other sides of each point or projection are made to
incline from the periphery to the point. The alternate rings or sections have
a hole at the centre suitable for turning on a cylindrical axis, and it has on
one side a projecting boss, on which the next or neighbouring ring or section
is received, and on which it turns freely. The rings or sections are connected
to their central naves or bosses by spokes.

by the said George William Robinson in the Great Seal Patent Office
on the 12th April 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WILLIAM ROBINSON, of Barton-on-Humber, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of October, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said George William Robinson, Her special licence that I, the said
George William Robinson, my executors, administrators, and assigns, or such
others as I, the said George William Robinson, 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 CLOD-CRUSHING ROLLERS," upon the condition
(amongst others) that I, the said George William Robinson, 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 George William Robinson, 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 Invention has for its object improvements in clod-crushing rollers.
For these purposes each roller is composed of numerous sections or rings as
heretofore, but in the construction of a roller according to these improvements
the periphery of each ring is made with spikes or projecting points, the two
outer sides of each of which are made to a curved form consisting of about
a quarter of a circle; the other sides of each point or projection are made to
incline from the periphery to the point. Each alternate ring or section has a
hole at the centre suitable for turning on a cylindrical axis, and it has on
one side a projecting boss, on which the next or neighbouring ring or section
is received, and on which it turns freely. The rings or sections are connected
to their central naves or bosses by spokes.

page_text: And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 is a section, and Figure 2 is a side view of a pair of rings or sections,
forming part of a clod-crushing roller constructed according to my Invention.
a is a longitudinal axis, on which the rings are placed; this axis at the two
ends projects beyond the series of rings or sections, and has mounted on it a
frame furnished with shafts like the frame of an ordinary horse roller. The
length of the axis a depends on the number of rings to be placed on it, but
it will usually be from six to eight feet long. The rings mounted on the
axis a are alternately of the forms shown at b and c, Figure 1. A plan of the
ring 6 is shown at Figure 3, and it will be seen that it is furnished with a
projecting boss b', on which the next ring or section c is mounted, so that it is
only every alternate ring or section which bears directly on the axis. In place
of forming the projecting bosses 6₁ all on one side of the rings or sections b,
bosses of half the length may be formed on both sides of these rings or
sections, and in place of making the rings or sections b and c of the same
diameter, each alternate ring may be made larger in diameter than the others,
and so as to turn very loosely on the boss of the next ring or section, as is
shown at Figure 4. But I would remark that I do not claim the constructing
rollers of rings or sections of two different diameters, placed alternately, as
rollers have sometimes been so constructed before the date of my Patent.
Figures 5, 6, and 7 show the manner in which the spikes or projecting points
on the peripheries of the rings or sections are formed according to my
Invention, and they represent respectively a plan, a longitudinal, and a
transverse section of one of such spikes or projections.
In witness whereof, I, the said George William Robinson, have hereunto
set my hand and seal, this Ninth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight
