PROVISIONAL SPECIFICATION.
Improvements relating to Agricultural Scarifiers.
I, EDWARD SLADE of El Hassa, St. Martins, Jersey, Smith, do hereby declare
the nature of this invention to be as follows:-
My invention relates to the well known class of implements employed in
agriculture, for stirring the soil without reversing its surface or altering its form.
In accordance with my invention I form a scarifier of the usual type but having
mounted thereon at the rear or trailing end a suitable bracket in which works a
manipulating hand wheel. This said manipulating hand wheel has an internal
screw threaded boss, into which works a longitudinal travelling rod or bar connected
at the front end to the socket head or steering post of the front or guide wheel.
I also employ a cross bar, shaft or lever having an arm or upright fixed in the
centre thereof, and connected to the longitudinal travelling bar; said bar shaft or
lever in connected in suitable bearings to the outer bars of the frame of the scarifier
whilst the bottom ends of same are attached to the axles of the two rear or trailing
wheels.
By turning the manipulating hand wheel to the left causes the longitudinal
travelling bar, to press the upright bar or lever forward and so raises the teeth
prongs or tines, to any required height, and by turning the manipulating hand
wheel to the right it draws the longitudinal bar or lever back, and so lets the teeth,
prongs or tines drop to any required depth.
Dated this 26th day of September 1891.

COMPLETE SPECIFICATION.
Improvements relating to Agricultural Scarifiers.
I, EDWARD SLADE of El Hassa, St. Martins, Jersey, Smith, do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:―
My invention relates to the well known class of implements employed in agriculture
for stirring the soil without reversing its surface or altering its form.
In order that my invention may be thoroughly understood I have annexed the
accompanying two sheets of drawings. Referring to which
Figure 1 represents a machine constructed in accordance with my invention, with
the teeth or scarifying devices in the raised position, whilst Figure 2 represents
the machine in the position as regards the teeth or scarifying devices, when same
are lowered and inserted in the soil.
In accordance with my invention I form a scarifier of the usual type but having
mounted thereon at the rear or trailing end a suitable bracket A in which works a
manipulating hand wheel B. This latter has an internal screw-threaded boss C
into which works a longitudinal travelling rod or bar D connected at the front end
to the socket head or steering post E of the front or guide wheel F. I also employ
a cross shaft or rod G having an arm or upright H fixed in the centre thereof and
connected to the longitudinal travelling bar D. The cross shaft or rod G is
connected by suitable bearings to the outer bars of the frame of the scarifier, whilst
the bottom ends of same are attached to the axles of the two rear or trailing
hools TI

page_text: Now on turning the manipulating hand wheel (say) to the left, the longitudinal
travelling bar D is caused to press the arm or upright H forward, and so raises the
teeth or scarifying devices to any required height, and by turning the manipulating
hand wheel B'to the right it draws the longitudinal travelling bar D'back, and so
lets the teeth or scarifying devices drop to any required depth.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is.
In agricultural implements of the kind herein referred to, the improved means
for raising and lowering the teeth or scarifying devices substantially as and for 1
the purposes herein set forth.
