PROVISIONAL SPECIFICATION.
New or Improved Machine or Apparatus and System for Cutting or
Holing Coal, Spavin, Fireclay, Shale, or Stone, and Removing
the Debris or Soil of the same.
I, RICHARD SUTCLIFFE of the Public Hall Barnsley in the County of York,
Mining Engineer do hereby declare the nature of this invention to be as
follows:-
My present invention relates to an apparatus or machine and system designed
more especially for the cutting of coal fireclay spavin shale stone or other such like
material and for the removal of debris or broken soil produced by the same
and the object of my said invention is so to arrange and construct said apparatus
that by its use the manual labour hitherto necessary in connection with such work
may be considerably lessened and the said work performed in a more speedy and
economical manner.
In attaining the said object therefore I arrange and construct an apparatus or
machine substantially as follows.
A horizontal cutting wheel or disc with cogs or teeth cast or made in the same
near to the periphery into which a driving wheel or pinion is made to work at right
angles or nearly so to the same. The said driving wheel or pinion is operated by a
shaft placed horizontally or slightly inclined to the horizon or by the crank shaft
of an engine or by an electric or other motor and when an engine is adopted as the
motive power a cylinder is placed on either side of the said crank shaft and con-
nected or secured together by plates of iron steel or other such like material
extending from one cylinder to the other and having bearings in the middle to
carry said crank shaft or other motion shaft together with the brackets arms and
fittings necessary to carry the aforesaid cutting wheel or disc with its connections
in the usual way. On the other end of said crank shaft or second motion or other
shaft as the case may be is fitted a worm screw which works into and rotates two
other wheels which are fitted on to other shafts and one of which shafts also carries
a worm screw by means of which it operates the drum and thereby hauls the
machine along the face as it cuts or holes. Or the haulage may be accomplished
by means of a ratchet wheel and fittings operated by a small eccentric or its
equivalent on the crank shaft or other shaft or by means of a series of wheels and
pinions or their equivalents.
The second wheel operated or driven by the said worm screw attached to the
aforesaid crank shaft or other shaft revolves or operates a vertical or standing shaft
which has a drum camm or pulley fitted on to its lower extremity and said drum
camm or pulley operates a chain band or conveyor which passes around other
horizontal pullies and carries plates scrapers or buckets which convey the debris or
broken material or earth from the aforesaid cutting wheel or disc and deposit it at
the goaf or gob side of the machine thereby preventing the said soil or broken
earth being taken back into the groove or cut by the rotation of the said cutting
wheel or disc and its connections. Or where preferred the said debris or broken
earth can be removed by means of a screw or worm conveyor operated by a
chain or other band or by a system of geared wheels or by a combination of both
as will be well understood and driven off or by the aforesaid crank or other
shaft.
Tool holders or boxes carrying two sets of tools or cutting pieces each are fitted
on the periphery of the aforesaid cutting wheel or disc in such a manner as that in
whichever direction the said cutting wheel or disc rotates the said cutting pieces
or tools come into proper position to cut the material as the machine advances. That

page_text: is to say the said two sets of tools or cutting pieces are fixed one turned each way
in the said tool holders which latter are made to work hinge like on a pivot or bolt
within a suitable range so as to present the front or foremost tools of the two sets
in the said holder or box in a proper position for cutting whichever way the said
cutting wheel or disc rotates so that when the rotating motion of the cutting wheel
or disc is from the left to right the cutting tools in the leading or front portion of
the tool holder project farther from the centre of the cutting wheel or disc than
those in the rear or back part of the same tool holder and having their cutting
edges in the proper position continue cutting the material against which the
machine moves so long as the rotation of the cutting wheel continues to the right
but on the rotating motion of the said cutting wheel or disc being reversed or made
to move from right to left the said tool holders lag behind or fall back on the
pivots or bolts until the other set of tools or cutting pieces which are placed so as
to cut with a left hand rotating motion project farther from the centre of the
cutting wheel or disc and cut the material so long as the left hand motion continues
thus having the cutters to alternate automatically with the change of the rotation
of the said cutting wheel or disc without having to change the said cutting pieces
or cutters.
At the hindmost end of the machine or at the back of the cutting wheel in the
groove or cut is placed a rake scraper or cleaner composed of three or more
parallel plates of iron or steel placed on their edges and of suitable dimensions
being secured together and attached to the coal cutting machine in such a manner
that as the machine moves forward all the loose debris or soil is drawn out
of said groove or cut and the cut left clear without the intervention of manual.
labour.
The whole apparatus or machine is made to travel when operating on four double
flanged wheels placed upon rails laid at the face which is to be cut and along
which it is drawn by means of a rope or chain on the drum referred to above.

New or Improved Machine or Apparatus and System for Cutting or
Holing Coal, Spavin, Fireclay, Shale, or Stone, and Removing
the Debris or Soil of the same.
I RICHARD SUTCLIFFE of the Public Hall Barnsley in the County of York
Mining Engineer 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 present invention relates to an apparatus or machine and system designed
more especially for the cutting of coal fireclay spavin shale stone or other such like
material and for the removal of the debris or broken soil produced by the same
and the object of my said invention is so to arrange and construct said apparatus
that by its use the manual labour hitherto necessary in connection with such work
may be considerably lessened and the said work performed in a more speedy and
economical manner.
In attaining the said object therefore I arrange and construct an an apparatus or
machine substantially as hereinafter described with reference to the accompanying
sheet of drawings.
Fig. 1 is a plan of my new or improved apparatus and
Fig. 2 is a cross sectional elevation of the same and like letters of reference
denote corresponding parts in each view.
A horizontal cutting wheel or disc A with cogs or teeth B cast or made in same
near to the periphery into which' a driving wheel C is made to work at right angles

page_text: or nearly so to the same. The said driving wheel C is operated by a shaft D
placed horizontally or slightly inclined to the horizan or by the crank shaft of an
engine or by an elictric or other motor and when engines are adopted as the
motive power a cylinder E is placed at either side of the said crank shaft' and
connected or secured together by plates F of iron or steel or other such like
material extending from one cylinder to the other and having bearings, G in the
middle to carry said crank shaft or other motion shaft D together with the brackets
arms and fittings necessary to carry the aforesaid cutting wheel or disc A with its
connections in the usual way. On the other end of said crank shaft second motion
or other shaft D as the case may be is fitted a worm screw H which works into
and rotates two other wheels I & I' which are fitted onto other shafts J J one of
which shafts J also carries a worm screw K' by means of which through worm
wheel L' it operates the drum L and thereby hauls the machine along the face as
it cuts or holes. Or the haulage may be accomplished by means of a ratchett
wheel and fittings opperated by a small eccentric or its equivalent on the crank
shaft or other shaft or by means of a series of wheels and pinions or their
equivalents. The second wheel I operated or 'driven by the" said worm" screw H
attached to the said crank shaft or other shaft D revolves or operates a vertical or
standing shaft J' which has a drum cam or pulley M fitted on its lower extremity
and said drum camm or pulley M operates a chain band or conveyor N which
passes around other horizontal pullies and carries plates scrapers or buckets P
which convey the debris or broken material or earth from the aforesaid cutting
wheel or disc A and deposits it at the goaf or gob side of the machine thereby
preventing the said soil or broken earth being taken back into the groove or cut
by the rotation of the said cutting wheel, or disc A. and its connections or where
preferred the said debris or broken soil can be removed by means of a screw or
worm conveyor operated by a chain or other band or by a system of geared wheels
or by a combination of both as will be well understood and driven off or by the
aforesaid crank shaft or other shaft D.
Tool holders or boxes R carrying two sets of tools or cutting pieces S & S¹ each
are fitted on the periphery of the aforesaid cutting wheel or disc A in such a
manner as that in whichever direction the said cutting wheel or disc rotates the
said cutting pieces or tools S or S¹ come into proper position to cut the material as
the machine advances that is to say the said two sets of tools or cutting pieces S & S¹
are fixed one turned each way in the said tool holders R which latter are made to
work hingelike on a pivot or bolt within a suitable range so as to present the front
or foremost tools of the two sets in the said holder or box R in a proper position
for cutting whichever way the said cutting wheel or disc A rotates so that when
the rotating motion of the disc A is from left to right the tools S in the leading or
front portion of the tool holder R project farther from the centre of the cutting
wheel or disc A than those in the rear or back part of the same tool holder and
having their edges in the proper position continue cutting the material against
which the machine moves so long as the rotation of the cutting wheel continues to
the right but on the rotating motion of the said cutting wheel or disc being
reversed or made to move from right to left the said tool holders R lag behind or
fall back on the pivots or bolts until the other set of tools or cutting pieces S¹
which are placed so as to cut with a left hand rotating motion project farthes from
the centre of the cutting wheel or disc A and cut the material so long as the left
hand motion continues thus having the cutters to alternate automatically with the
change of the rotation of the said cutting wheel or disc A without having to change
the said cutting pieces S and S' or cutters.
At the hindmost end of the machine or at the back of the cutting wheel A and
in the groove or cut is placed a rake scraper or cleaner T composed of three
or more parallel plates of iron or steel placed on their edges and of suitable
dimensions being secured together and attached to the coal cutting machine in such
a manner that as the machine moves forward the loose debris or soil is drawn out

page_text: of the said groove or cut which is by this means left clear without the intervention
of manual labour.
The whole apparatus or machine is made to travel on four double flanged
wheels U placed upon rails laid at the face which is to be cut and along which it is
drawn by means of a rope or chain on the drum L.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. An apparatus employed for the purpose specified the use of a cutting wheel A
with self adjusting tools or chisels S and S¹ and tool boxes R the use of a chain or
other band conveyor N with scrapers or buckets P attached or other equivalent for
removing the debris and the use of a rake scraper cleaner or plough T for clearing
out the cut or groove substantially as described and set forth in part by the accom-
panying sheet of drawings.
2. A machine or apparatus combined and arranged substantially as described
and used for the purpose specified.
