WHEREAS Her present most Excellent Majesty Queen Victoria, by ei
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Butain and Ireland bearing date at Westminster, the Tenth day of July, in
the tenth year of Hei reign, did, for Herself, Пlei hens and successois, give
and giant unto nic, the said Robert Beart, my exois, adñions, and assigns,
Hei especial licence, full power, sole privilege and authouty, that I, the said
Robert Beart, my exois, admors, and assigns, or such others as I. the said
Robert Beart, my exois, adiñois, or assigns, should at any time agree with
and no others, fioin time to time and at all times during the term of yeais
therem expressed, should and lawfully might make, use, exercise, and vend
within England, Wales, and the Town of Berwick-upon-Tweed, my Invention
of "IMPROVEMENTS IN TILLING LAND," in which said Letters Patent is con-
tained a proviso that I, the said Robert Beait, shall cause a particular
description of the nature of my said Invention, and in what manner the same
15 to be performed, by an instrument in writing under my hand and seal, to
be iniolled in Hei said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appeal
NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Beart, do hereby declare that the nature of my said Invention, and

page_text: ascertained in and by the following statement thereof, reference being had to
the Drawings heicunto annexed, and to the figures and letters marked thereon,
that is to say -
My Invention relates to improvements in machinery for scanfying and
pulverizing land, and in order that my Invention may be most fully under-
stood and readily carried into effect, I will proceed to describe the means
puisued by me
DESCRIPTION OF THE DRAWINGS
Figure 1 shows a side view, and Figure 2 a plan of the machinery com-
bined according to my Invention, Figure 3 shows a side view, and Figure 1
a plan of the machinery for scarifying when the pulverizing and cleansing
machinery has been removed, and times of the other machinery have been
atranged for scarifying only Figure 5 shews a side view and an edge view
of one of the rolling surfaces separately, which are placed on a cylindrical
shaft having a projecting lib, as I prefer that the the surfaces of the pul-
venizing wheels should have a slight movement on the axis, but that when
they are at work, except when the machine is turning, that they should be
prevented in every way moving on the axis The pulverizing and cleansing
wheels are so aanged that they, by then teeth, may come into action on the
land as the surface thereof is raised and uses up between the times, and in
such manner that the teeth of the pulverizing wheels will penetrate the raised
surface of the land, and cause it to be broken, and will also assist in prevent-
ing the roots and other matters using up the stems of the scarifying times
a, a, is the fiamming of the machinery, the nature of which will readily be
understood on examining the Drawings The machine is camed by four
wheels, two fore wheels b, b, and two hind wheels c, c On the axle of the
fore wheels b is fixed an upright d, on which the front part of the frame a can
be caused to move up and down to regulate the depth of the tines, 01, when
the machine is not in use, to aid in withdrawing them altogether from the
land by means of the lever e, which moves on its fulcrum f, and at its longer
end receives support by apin e, in the plate e, which has several holes for
the pin e', whereby the depth to which that end of the level e may descend
may be regulated, and the fore wheels can move and perform a locking action
nespect to the frame when turning the machine. The horses are attached
to the bai g. When the machine is to be used for scarifying and pulvensing,
the scarifying tines, h, h, are ananged, as shown in Figures 1 and 2, but when
the pulverizing machinery is removed, part of the tines h, h, we removed,

page_text: and the tines 1, 2, Figures 4 and 5, are applied, and then the machine is
similar to an ordinary scarifying machine. 3, 7, are the pulverizing wheels of
surfaces, each having teeth at their outer cucumference, as shown
These
wheels are placed on the axis k, which has its bearings in the additional
side lever frames a', a', which are fixed to the side fiamings a, a, by the necks
01,axes l, l, and they are fixed and adjusted to the desued position by the bolts
m, m, which enter between the teeth in the sector lacks a², a², at the front
ends of the side lever fames a¹, a², and according to the positions in which
the bolts m, m, aie placed in the sector racks a, a³, so will be the depth to
which the teeth on the wheels, will be caused to enter the land in relation
to the depth of the tines And although these toothed surfaces may be fixed
to the axis, yet I prefer that they should have a little play, but that. they
should all go together when at work, for which reason the opening through the
roller surfaces for the axis are formed, as shewn, and there is a projecting
stop along the axis, in order to prevent the surfaces moving separately when
at work, except when the machine is tuining The hind canying wheels c, c,
are mounted on a cranked axis c, moving in bearings n, n, fixed to the bar or
beam which canes the tines; and in order to lower the carrying wheels and
aise the tines, as well as the wheels, the screw.dx150 is employed which
tuns in bearings p, p, fixed to the frame a, a, and on the sciew o, a screw
nut q moves to and fio, according as the screw, is turned in one direction or
the other is a forked connecting rod attached to the nut g, and to the
aim on the axis c', by means of which the cranked axis c¹ may be caused to
assume the desued position, so that the back part of the fiame of the machine
may be raised or lowered to regulate the depth of the scarifying teeth and the
toothed wheels, or to raise them wholly out of the land. But as 111 some cases.
when paring land, it may be desirable sometimes to have one of the hind
wheels at a different elevation to the other with respect to the framing of the
machine, I have, in Figure 6, shown an aliangement for this purpose C IS
one of the hind carrying wheels, which tuin upon axes c, affixed to the bar c³,
which is capable of sliding up or down through the eyes a³, and the position
of the bar c', and the consequent height of the sides of the frame a, will be
egulated by a lever c', (one to each wheel,) which is connected to the bar c
by a pin passed through one of the holes in the upper part of the bar c³,
the levers c', being supported by an axis c³, carried by the framing a, as
shown, and it is adjusted by a pin passed through one of the holes in the
plate a*.
Having thus described the nature of my said Invention, and the manner in
which the same is to be performed, I would have it understood that I do not

page_text: claun any of the parts separately, nor do I confine myself to the details, so
long as the peculiar character of the Invention be retained But what I
claim is, combining pulverizing and cleansing toothed wheels with scarifying
machinery, as herein described.
