Year: 1875

page_text: LETTERS PATENT to George Parker, of Denaby, in the County of
York, for the Invention of "AN IMPROVED MACHINE OR APPARATUS FOR
'RIDDLING' AND LOADING COAL OR OTHER MINERALS."
Sealed the 3th August 1875, and dated the 16th February 1875..
PROVISIONAL SPECIFICATION left by the said George Parker at the
Office of the Commissioners of Patents, with his Petition, on the
16th February 1875.
"I, GEORGE PARKER, of Denaby, in the County of York, do hereby
declare the nature of the said Invention for "AN IMPROVED MACHINE OR
APPARATUS FOR RIDDLING' AND LOADING COAL OR OTHER MINERALS," to be as
follows:-
'
This Invention, which relates to an improved machine or apparatus
for riddling or screening and loading coal or other minerals has for its
objects, the lessening of the manual labour required to load coal and
other minerals into corves or waggons or other receptacles by reducing --
to a minimum the height to which the coals or minerals have to be lifted.,
by manual labour, thus enabling a man to load or raise more than twice

page_text: the quantity he could if he had to lift it direct into the corf or other
receptacle; and the effecting of the thorough riddling or screening of the
coal at the time of loading in or from the mine (or elsewhere), whereby
the important advantage is attained of the waste or small or smudge
coal being at the first separated from that of the more useful size, so
that the labour of raising the less useful kind from the mine will be
saved.
The machine or apparatus is constructed with two, four, or more
octagonal or other suitably shaped wheels and shafts, to which motion is
imparted by a suitable arrangement of ordinary gearing actuated by a
handle or crank or by any convenient motive power. Round these
wheels are passed endless chains, belts, or bands, across which are
fastened a series of projecting concaved bars (or their equivalents) per-
forated or constructed with suitable openings, a certain number of the
bars being angular or made as steps to carry the coal or mineral forward.
This arrangement of mechanism is carried by or in a suitable framing
fitted with wheels so as to allow of easy locomotion.
The coal or mineral is placed by manual labour only on the lowermost
of the bars in the space between the chains, to which the moving of the
octagonal shaped wheels gives a forward and jerking motion, which at
the same time riddles or screens the small from the serviceably sized
coal through the perforations or openings in the bars, and carries the
screened or useful coal or mineral up to the top level of the corf or
receptacle, into which it falls.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 25
filed by the said George Parker in the Great Seal Patent Office on
the 13th August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
PARKER, of Denaby, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 30
Patent, bearing date the Sixteenth day of February, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,.
give and grant unto me, the said George Parker, Her special licence

page_text: that I, the said George Parker, my executors, administrators, and assigns,
or such others as I, the said George Parker, 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 "AN IMPROVED MACHINE OR APPARATUS
' RIDDLING' AND LOADING COAL OR OTHER MINERALS," upon the condition
(amongst others) that I, the said George Parker, 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.
FOR
NOW KNOW YE, that I, the said George Parker, 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 in writing, and on reference being had to the
accompanying Drawings, that is to say :-
This Invention, which relates to an improved machine or apparatus
for "riddling," screening, and loading coal or other minerals, has for its
objects, the lessening of the manual labor required to load coal and
other minerals into corves or waggons or other receptacles by reducing.
to a minimum the height to which the coals or minerals have to be.
lifted by manual labour, thus enabling a man to load or raise more than
twice the quantity he could if he had to lift it direct into the corf or
other receptacle, and the effecting of the thorough riddling or screening
of the coal at the time of loading in the mine, whereby is attained the
important advantage of the waste, small, or smudge coal being at the
first separated from that of a more useful size, so that the labor of raising
the less useful kind from the mine will be saved.
Such being the nature and object of my said Invention I will now:
proceed to describe more in detail the manner in which the same is to.
be or may be performed or carried into practical effect; and in order
that the same may be distinctly understood I have annexed hereunto
one Sheet of Drawings illustrative thereof, and have marked the same:

page_text: with figures of reference corresponding with those in the following
explanation thereof, that it to say :-
On the accompanying Sheet of Drawings, which are drawn to a scale
of one inch to one foot,-

Figure 1 represents a side elevation of my improved riddling, screening,
and loading apparatus in position for loading into an empty waggon;
Figure 2, a plan view of the riddling, screening, and loading apparatus.
alone; and Figure 3 an end elevation of the waggon, and what would be
seen of the riddling, screening, and loading apparatus.
The improved machine or apparatus, it will be seen, is constructed
with two, four, or more octagonally or other suitably shaped wheels or
rollers 1 (or their equivalents) on shafts 2, to one of which motion is
imparted by a suitable arrangement of ordinary gearing 3, actuated by a
handle or crank 4, or by any convenient motive power. Round these
wheels 1 are passed endless chains, belts, or bands 5 (or their equiva-
lents), across which are fastened a series of projecting concaved or
hollowed bars 6 (or their equivalents) perforated or made with suitable
openings. A certain number of these bars are made angular or as steps
to carry the coal or mineral forward. This arrangement of mechanism
is carried by or in a suitable framing 8, fitted with wheels 9, so as to
allow of easy locomotion.
To attain the objects of the Invention the coal or other mineral is
placed by manual labor only on to the lowermost of the bars 6 in the
space between the chains 5, to which the operation of the octagonally.
shaped wheels 1 gives a forward and jerking motion, which at the same
time riddles or screens the small from the serviceably sized coal through
the perforations or openings in the bars 6, and carries the screened or
useful coal or mineral up to, over, and above the top level of the corf or
other receptacle 10, into which it falls, the small coal falling through
the openings to an incline 11, down which it slides.
Having now particularly described and ascertained the nature and
object of the said Invention, together with the manner in which the
same is to be or may be performed or carried into practical effect, I
would remark in conclusion that I claim as my Invention, the construc-
tion and use of apparatus for the purposes of riddling, screening, and.
loading coals or other minerals, and to attain the objects herein-before.
specified, substantially as herein described and as illustrated on the

page_text: accompanying Drawings; and more particularly I claim, the novel and
peculiar combination as a machine for these purposes of octagonally
or other suitably shaped wheels or rollers (or shafts) on shafts, through
and by which motion thereto can be conveniently applied, with endless
chains, belts, or bands (or their equivalents) carrying a continuous series
of transverse perforated, concaved, or hollowed and stepped bars, and
with or without an incline, the whole being supported by a suitable
framing provided with wheels for more easy locomotion.
In witness whereof, I, the said George Parker, have hereunto set
my hand and seal, this Second day of August, in the year of our
Lord One thousand eight hundred and seventy-five.
GEORGE PARKER. (L.S.)
