IMPROVEMENTS IN MACHINERY FOR CLEANING AND DRESSING LAND AND MEADOWS
Year: 1884

page_text: We JOHN GLEDHILL and EDWIN GLEDHILL of St Stephens Iron Works, Lindley
near Huddersfield in the County of York, Engineers and Crane Makers do hereby
declare the nature of our invention for "IMPROVEMENTS IN MACHINERY FOR
CLEANING AND DRESSING LAND AND MEADOWS "
to be as follows:-
Hitherto land and meadows have been cleaned and dressed by means of a mass
of chains, with or without spikes and sometimes with branches of thorn or other
trees.
Our Invention consists in the employment of a rotary disc or roller, carried and
Bupported by wheels, moved up and down the land or meadows by manual or horse
power. This disc or roller is provided with a series of bars or rails placed parallel
with the axis, and upon these bars or rails are attached any required number of
flexible teeth, pins or prongs, so that as the disc revolves, the flexible teeth will be
carried around thereby, but will readily yield to stones or other hard materials, or
irregularities on the surface of the land or meadows.
'
By this means the land is readily and quickly cleaned and dressed, the flexible
teeth at all times yielding to unevenness in the land, thereby stiffness and breakage
of the parts are prevented.
:
By preference the flexible teeth are composed of hardened and tempered steel
wire, but it will be evident that teeth made of other flexible materials may be used
instead.

page_text: We JOHN GLEDHILL and EDWIN GLEDHILL of St Stephen's Iron Works, Lindley
near Huddersfield in the County of York, Engineers and Crane Makers, do hereby
declare the nature of our invention for "IMPROVEMENTS IN MACHINERY FOR
CLEANING AND DRESSING LAND AND MEADOWS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:—
Hitherto land and meadows have been cleaned and dressed by means of a mass
of chains, with or without spikes and sometimes with branches of thorn or other
trees.
Our Invention consists in the employment of a rotary disc or roller carried and
supported by wheels moved up and down the land or meadows by manual or horse
power. This disc or roller is provided with a series of bars or rails placed parallel
with tho axis, and upon these bars or rails are attached any required number of
flexible teeth, pins or prongs so that as the disc revolves, the flexible teeth will be
carried around thereby, but will readily yield to stones or other hard materials or
irregularities on the surface of the land or meadows.
In order that our Invention may be better understood we herein give referenco
to the accompanying sheet of drawings wherein A is an end elevation of a
disc or roller provided with radial arms B on each of which is fixed a bar C
running parallel with the axis of the disc. This bar C is bored with any required
number of holes into which we drive, tightly, the flexible teeth or pins D as shewn
in section Fig 1. The spiked disc thus made is then attached to wheels, carried
by suitable framework, and on the wheels rotating, the spiked axis, is caused to
revolve. The spikes D are long enough to reach the ground, consequently as the
disc rotates the land is readily cloaned and dressed, the flexible spikes at all times
yielding to unevenness in the land so as to prevent stiffness and breakage of the
parts.
By preference the flexible teeth are composed of hardened and tempered steel
wire, but it will be evident that the teeth may be made of untempered steel wire,
or other flexible material may be used instead.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what
we claim is :—–—–—
In a rotary disc, the employment of flexible teeth or pins for the purpose of
cleaning or dressing land, in manner substantially as set forth.
