PROVISIONAL SPECIFICATION.
Improvements in Machines for Cutting Coal and other Materials.
I, GEORGE WILLIAM ELLIOTT of 160 Shirebrook Road, Heeley, Sheffield,
Mining and Mechanical Engineer do hereby declare the nature of this invention
to be as follows:-
This invention refers chiefly to the mode of using machines for cutting coal and
other materials, and the apparatus connected therewith.
The mode of using these machines according to this invention, is to attach the
cutting machine, whether rotary or percussive, to one end of a comparatively long
lever, and provide a swivelled fulcrum, or equivalent arrangement, which can be
used at any other part of it, and the power to move and control it, applied at any
suitable position.
.
By this arrangement the cutter of the machine can be moved in a vertical or
an horizontal plane, or any other desired direction, and so made to cut a slot in..
the material acted upon.
A guide may be used at or near one end of the lever to cause the lever and
cutter to move in the plane or path required.
The cutting machine may also be attached to one end of the lever and connected
by a bar to the cutter at the other end of the lever.
Another arrangement of lever for working the cutting machine is to attach it to
one end of the lever and a balance weight at the other, with the swivelled fulcrum
between them.
An arrangement is also provided for advancing the cutter endways, in the
direction of the length of the lever so as to cut the slot as deep as necessary.
One arrangement for advancing the cutter for this purpose is to attach the cutting
machine to one end of the lever by a sliding clip so that it may be slid along the
lever as required, by means of a rack and pinion or equivalent device.
Instead of this arrangement the machine may be attached firmly to the lever, and
the lever made to advance through the swivelled fulcrum as required, by means of
a rack and pinion or otherwise.
For some purposes the cutting machine or the cutter is attached to the end of
the lever so that it can be turned on a joint to any angle with the lever or kept in
a straight line with it.

COMPLETE SPECIFICATION.
Improvements in Machines for Cutting Coal and other Materials.
I, GEORGE WILLIAM ELLIOTT, of Meersbrook Park Road, Heeley, Sheffield,
in the County of York, Mining and Mechanical 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:-
In adapting this invention to machines and the apparatus connected therewith,.
for cutting coal and other material, it will be seen by refering to the accompanying
sheets of drawings some of the various methods or devices I employ. The same
letters of reference are used to indicate similar parts of the various figures or
drawings.
In the machine illustrated by Figures 1 and 2, Sheet 1, I attach the cutting..
г

lever is provided with a swivelled fulcrum C, of suitable design and material, and
which can be carried in any approved bearings on a trolly or wagon D.
machine. A can be attached to the cutter E, by a bar F, running the length of
lever B.
The
When necessary the trolly D, can be secured in position by clips G, to rail, or
by approved equivilent arrangement. The cutter E can be advanced end ways
into the material being operated upon by means of a screw H, worked in trolly D,
by' worm, worm wheel, and hand wheel J, fixed in any convenient position. The
machine can be moved horizontally by means of pivot K, and in a vertical direc-
tion on the fulcrum trunnions C¹.
By another arrangement see Figures 3 and 4, Sheet 1, I construct a machine
having a cutting apparatus complete A, which is placed on the end, or in any
suitable position, of a bar B, hollow or otherwise, or of a length of tube the
apparatus A, can be moved in a forward direction by any approved mechanical
means. If a rack and pinion M is used as shewn on illustration I provide a pawl
or other equivilent device to prevent the machine slipping back when working, but
it can be operated by a worm and rack or other suitable arrangement.
bar B is provided with a suitable fulcrum C, and a balance weight N, at the
opposite end to the one carrying the cutting machine A.
The
In the arrangement shewn by Figures 5 and 6, Sheet 2, the cutting apparatus E,
is worked in a similar manner to that shewn by Figures 1 and 2, Sheet 1, but
instead of advancing the machine forward by means of a screw H, in the trolly D,.
I provide the fulcrum portion C, with a pinion O and on the arm or long lever B
I place a rack P, actuating the whole by a hand wheel, and thus propelling the
machine A, and lever B, through the fulcrum C. In this instance a pinion and
rack is shewn, but if desired a worm or any other suitable arrangement can be
substituted. The gearing shewn underneath the trolly D for the purpose of rotating
the lever B, and cutting machine A, in a horizontal direction can be dispensed with
if required, or replaced by other suitable appliance.
Figures 7 and 8, Sheet 2, shew another method of advancing the cutting.
machine E into the material being operated upon. In this case the arm or lever B,
is advanced through the fulcrum C, by a rack R and worm S, which can be worked
or controlled by the man in charge, from the extreme end, or any portion of the
extended lever B, by means of the hand wheel S¹ mitre wheels and rod T. The
rod can be replaced by an endless chain or similar equivilent. The fulcrum C in
this case is not supplied with trunnions C¹, but has a neck or projection C³ on the
underside, of suitable size and shape, this projection or neck passes through a
horizontal bracket or carrier Z, which carrier is more fully described hereafter.
This machine can be moved in any desired direction, vertically or horizontally,
and is easily transported to and from the workings, and a trolly with suitable
bearings can be used for moving the machine from place to place.
Figures 9 and 10 Sheet 3, shew a modification of machine placed on a bar or
tube B, and having a balance weight N, and fulcrum C.
In this example the cutting machine A, can be fixed in any position in relation
to the bar B, vertically, horizontally, at right angles, or in line with the bar on
which it is carried by means of a clip or universal joint U. The bar can be moved
endways by sliding same through the fulcrum C by rack, worm or pinion, or any
other means as before described.
Figures 11 and 12 Sheet 3, illustrate one kind of the cross bearings Z, before-
mentioned and is made of plates, channel irons or of any suitable material and
design having a fixed pivot Z at one end and an adjustable screw and pivot Z³, at
the other end. In using this support it is fixed horizontally or vertically across the
heading and firmly screwed into the sides. The neck on fulcrum C2, is then passed
in or between and through the space V, and secured by any mechanical means.
The cutting machine can then be worked in any direction across the face, the
full width of the working.

page_text: Figures 13 and 14 Sheet 3, illustrate a modification of cross bar or bearer, it can-
be made of tubular section W, and is provided at the ends with the necessary
pivotting point Z' and screw Z, but instead of the fulcrum neck C³, passing through
a slot I fix or provide a clip X, or similar device which slides when required along
the outside of tube W and which clip X carries with it the arm or lever B, carry-
ing the cutting machine.
This lever can be easily moved in a horizontal direction by either easing the
clip X, and sliding it bodily, or rotating the lever B on the neck C¹.
Figure 15 Sheet 3 shews an appliance, Q, hollow or otherwise, to be fixed between
floor and roof, for the purpose of acting as a guide to the long lever B, carrying
the cutter E. This appliance can be fixed in any required position, vertically
horizontally or otherwise, thus causing the arm B, and cutter E to move and work
in any desired path. It is provided with a claw Y, at one end, pivotted to suit
any inequality in the surface and having a screw or similar arrangement at the
other end for fixing firmly in position. I also provide it with a suitable sliding
bracket Y to which is attached the lever B, this bracket or guide can be worked
The sliding
by the hand, chain and blocks, or any other gearing suitable.
bracket Y can be made of any requisite size and shape.
The foregoing descriptions of my invention apply to cutting machines, rotary or
percussive, and enables the cutting portion of the machine to be placed at the end
of a long lever, and that part providing the requisite power being supported or
fixed in any suitable position, at the same time placing the whole under the control
of the operator.
The whole of the methods illustrated can be adapted to work in connection with
the cross bar or support Z, and the vertical or horizontal guide Y*.
The trolly
shewn is not indespensable to the working of the machine and may be merely used
for easy conveyance. Any of the elongated levers can be worked forward endways
through fulcrum C by rack, worm or pinion or other equivilent. The lever B, can
be made of tubular section or built up of suitable material.
I do not confine myself to the designs or arrangements shewn or illustrated on
drawings, but they will be found sufficient to fully explain the principles of my
invention. No provision is shewn on the arm or lever B, for attachment to guide Y
but any simple mechanical device can be applied. The arrangements for propelling
the cutters forward can be made to work automatically if found advantageous
to do so.
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;
1st. The use of cutting machines having the cutter at one end of a lever, with
the driving power attached to any other suitable part, the said arm or lever
working in, or through, a fulcrum carried on a trolly or supports, as generally
herein described and illustrated on drawings.
2nd. The use of cutting machines attached to a long lever having a balance
weight and fulcrum with suitable bearings and also arranged to travel forward
endways into the material by means of rack, worm, wheel pinion or screw, and
having a swivelled or universal joint or clip to enable the machine to be used in
any approved path or direction, substantially as herein described and shewn on
drawings.
3rd. The use of cutting machines as herein described and shewn, having a guide
or similar contrivance to cause the cutter to travel in any path or plane as
desired the same being actuated when necessary by screw, pinion and rack or chain
and blocks or their equivilents.
4th. The use of cutting machines and the apparatus connected therewith,
substantially as herein described and shewn.
5th. The use of cutting machines and any combination of any of the parts or
methods herein described and illustrated.

page_text: 6th. The use of cutting machines, rotary or percussive, constructed or
arranged wholly, or in part, or in combination of part or parts, actuated or
worked as is generally herein described and illustrated on accompanying sheets of
drawings.
Dated this Sixth day of January 1893.
