A Method of and Apparatus for Getting Coal, Shale or other like
Minerals.
I, WILLIAM WALKER of Saltburn by the Sea in the County of York, Mining
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to the getting of coal, shale and other like minerals by the
employment of an apparatus which is applicable generally to the faces of workings,
whether these are thick or thin, wide or narrow. The machine may be worked by
compressed air, water under pressure or electricity, whichever, of these motive
agents can be most conveniently applied, but the motor, whatever it may be, must
be such that it is carried on the same truck with the rest of the apparatus giving
rotation to the main driving shaft of the machine. This is a horizontal shaft
mounted in bearings on a turn plate which is itself mounted with a perch pin on
a wheeled truck so that the main shaft can be turned horizontally in any direction
relatively to the wheels of the truck and the rails or trams on which they run.
bearings of the main shaft form trunnions on which can be turned independently
of each other, in vertical planes, two pairs of radial arms.
The
Each pair of these arms have at their ends bearings for a spindle, which can be
swept round with the arms always parallel to the main shaft, and which can also be slid
longitudinally through its bearings and through a pinion having a feather engaging
in a long slot of the spindle. The two pinions, one for each spindle gear with a
toothed wheel on the main shaft, but each is provided with a suitable disengaging

end of each spindle is fixed a tubular saw, on the other hand is fitted loose a hand
wheel by which the spindle and saw can be advanced or retracted.
Besides the saw
there may also be fixed on the end of the spindle a boring auger. In operating
with this apparatus, I run the truck on to the floor or bottom of the seam or on to
rails or tram plates parallel with the face of the working, and placing it at one,
say the left, end of the working face with its main shaft at right angles to the face,
I set the one pair of radial arms and the spindle which they carry so that the saw
on that spindle shall cut into the upper left hand corner, and I set the other pair
of arms and spindle so that their saw shall cut into the lower left hand corner.
When the saws, which may be 1 foot in diameter have advanced to the required
depth, such as 1 foot, into the mineral, I withdraw them. I then advance the machine
about a foot and again work in the saws, and thus I proceed until a row of circular
chases is cut into the mineral along the top and a row along the bottom of the
working face of the seam, I prize or wedge out the cores of the chases and thus
form as it were a continuous groove above and below the middle part of the seam
which may then be broken down in mass, or cut out in cores by the machine.
When it is necessary, I employ the saws also to cut circular chases in a vertical
row at each side of it so as to separate the ends of the middle body from the side
walls of the working. In order to facilitate the removal of the cores left by the
saws I employ the augers along with the saws for some of the cuts, so as to drill in
some of the cores central holes in which a lever may be inserted to prize out the
cores. When compressed air is used as the working Huid, the engine cylinders may

shaft, or they may be arranged on the truck to work a separate crank shaft geared
to the main shaft. Water under pressure may be applied to work on the truck a
turbine having its shaft geared to the main shaft, and in like manner electricity may
be used to work on the truck a motor geared to the main shaft.

A Method of and Apparatus for Getting Coal, Shale, or other like
Minerals.
I, WILLIAM WALKER, of Saltburn by the Sea, 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 invention relates to the getting of coal, shale or other like minerals by the
employment of an apparatus which is applicable generally to the faces of workings
whether these are thick or thin wide or narrow. I shall describe this apparatus
referring to the accompanying drawings.
Fig. 1 is a longitudinal section, Fig. 2 is an end view and Fig. 3 a plan.
On a truck having wheels A which may be suited to run on rails or trams or on
the ground, is mounted by a perch pin B the framing C of the machine which can
be turned round the perch pin as an axis so as to have its working directed at
any angle to the track along which the truck travels. The frame Chas bearings
for the main shaft D which may be the crank shaft of an engine worked by
compressed air or water under pressure, or may be a countershaft driven by suitable
gear from a turbine or from an electric motor, it being understood that the motor
whatever it may be, must be such that it is accommodated on the framing of the machine,
giving rotation to the shaft D. The bearings of the shaft D form trunnions on which
can be turned two arms E one at each end of the machine and two discs F to which
these arms are bolted. Also on the bosses of the discs F can be turned another
pair of arms G which can be clamped to the discs F in any position relatively to that
of the arms E. In the arms E and also in the arms G are formed bearings for
spindles H which can, by moving the respective arms which carry them, be swept
round the axis of D always parallel thereto. On these spindles H are pinions [
which gear with a wheel J on the shaft D. Each of the spindles Ef by the hand
applied to a loose wheel K, can be slid longitudinally through its bearings and
through the pinion I and it has a long slot receiving a feather in a clutch L which
by a hand lever can be engaged with or disengaged from the pinion I. On the end
of the spindle H is secured a cylindrical saw M, which is preferably made as a
cylindrical shell with several cutters N fixed in its front edge.
The spindle H may also have fixed to its end a boring auger which can bore a
central hole in the mineral while the saw M is cutting a circular chase therein.
In operating with this apparatus I run the truck along the floor of the working
or on rails or trams parallel with the face of the working, and placing it at one end
say the left end of the working face with its main shaft at right angles to the
face, I set the one pair E of radial arms and the spindle which they carry so that
the saw on that spindle shall cut into the upper left hand corner, and I set the
other pair G of arms and spindle so that their saw shall cut into the lower left hand
corner. When the saws, which may be 1 foot in diameter, have by hand pressure
applied to the wheels K, been advanced to the required depth, such as 1 foot into
the nineral, I withdraw them. 1 then advance the machine about a foot and again
work in the saws; and thus I proceed until a row of circular chases is cut into the
mineral along the top and a row along the bottom of the working face of the seam.
I prize or wedge out the cores of the chases, and thus form, as it were, a continuous

page_text: groove above and below the middle part of the seam which may be then broken down
in mass or cut out in cores by the machine.
When it is necessary I employ the saws also to cut circular chases. in a vertical
row at each side of the working face so as to separate the ends of the middle body
from the side walls of the working. In order to facilitate the removal of the cores
left by the saws I employ the augers along with the saws for some of the cuts so as
to drill in some of the cores central holes in which a lever may be inserted to prize
out the cores.
Having now particularly described and ascertained the nature of this .inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is 1. I make no claim to the herein described method of getting coal, shale
or other like minerals by cutting into the face of the seam operated on a series of
circular chases and breaking down the cores, and intermediate parts, but what I
cluim is:
2. For operating in the manner above referred to in the preceding claim, the use
of apparatus substantially as described and illustrated by the drawings.
