JOSEPH LODGE Machinist Lydbrook Gloucestershire I do hereby declare the
nature of an invention for IMPROVEMENTS IN MACHINERY FOR CUTTING COAL AND
SIMILAR SUBSTANCES to be as follows:-
The machine would be driven by means of compressed air or steam, and will
oscillate in any manner required, either horizontally or vertically, at the same time
doing its work, It may be used for cutting coal when in its natural state in the
earth, or for cutting other substances, such as stone, &c.
The air or steam cylinder A the connecting plate B and the bottom part of guide
block C are in one. To one end of piston rod D the straight tool F is connected,
but for cutting underneath, the crank joint E should be connected with the
piston rod D, and the straight tool F inserted in crank E; or when circumstances
require, the bent tool G may be used in place of the cranked joint E. By reversing
crank E and tool G, it would cut part required. In the guide block brass H a key
or feather occupies a groove I. made lengthways in the piston rod, and runs the
length of the stroke from guide block to cylinder; but not into it. The purpose of
this groove and key is to keep piston rod and cutter in right position.
The iron
Against guide block H an indiarubber collar is placed on top of which is a
loose iron ring marked J. which is kept in place by two iron studs.
ring K which is made fast on piston rod to give motion to valve lever L will strike
the loose ring on top of rubber collar before the piston comes in contact with the
end of cylinder. This gives the workman notice to turn the feed screw M to
prevent a breakage.
On side of cradle is a groove in which to carry machine down the length of feed
screw M. to give chisel a length of feed. Whilst the screw N. on angle iron frame O.
is carrying the machine backwards and forwards, an oscillating motion may be
obtained by means of a joint T. underneath to suit the purpose, For road cutting-
either coal or drift-there is a carriage with a perpendicular bar P. on which is a
rack motion with pinion R. This pinion is worked by a screw S. so that machine
may work in any position required and if necessary oscillating at the same time
by means of joint on machine to suit the purpose, The centre bar should be made
fast to roof or sides to steady machine.

page_text: The rack Q. will carry machine up or down for cutting sides or along bottom or
top as case may require and at the same time will oscillate when required.
The chief parts of this machine which I claim are:-
(1.) That machine will travel (on angle iron frame O), strike and oscillate at one
and the same time.
(2.) Crank joint E on piston rod so as to suit the cutting of coal top, bottom, or
side if required, and bent tool G for similar purpose, also straight tool F. for cutting
near centre.
(3.) The open part of machine in which the grooves in piston rod work upon the
feather or key in guide block brass to keep the cutter in its proper position, the
groove not travelling into cylinder, so that air or steam cannot escape.
(4.) Enabling workman to see the notion of valve lever, so as to be able to
adjust it when required.
(5.) The loose ring J. and. rubber collar in guide block, which gives the workman
notice to turn feed screw, in order to prevent a breakage.
(6.) The rack motion on perpendicular. bar P and screw with pinion R. for
carrying machine up and down, or backwards and forwards so that it may cut on
any side and oscillate at the same time if required.

Improvements in Machinery for Cutting Coal and similar
Substances.
JOSEPH LODGE Machinist Lydbrook, n Ross Gloucestershire. I do hereby declare
the nature of an invention for IMPROVEMENTS IN MACHINERY FOR CUTTING COAL
& SIMILAR SUBSTANCES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, referring
to the drawings filed with my provisional specification:
The machine would be driven, by means of compressed air or steam and will
oscillate in any manner required, either horizontally or vertically at the same time
doing its work. It may be used for cutting coal when in its natural state in the
earth, or for cutting other substances, such as stone, &c.
The air or steain cylinder A, the connecting plate B and the bottom part of
guide block C are in one. To one end of piston rod D the straight tool F is
connected, but for cutting underneath, the crank joint E should be connected with
the piston rod D and the straight tool F inserted in crank E, or when circumstances
require, the bent tool G may be used in place of the cranked joint E. By reversing
crank E and tool G it would cut part required. In guide block brass H a key or
feather occupies a groove I made lengthways in the piston rod, and runs the length
of the stroke from guide block to cylinder but not into it, The purpose of this
groove and key is to keep piston rod and cutter in right position by taking out
the key, the tool may be made to revolve as circumstances require. Against guide
block H an indiarubber collar is placed, on top of which is a loose iron ring
marked J which is kept in place by two iron studs, The iron ring K which is
made fast on piston rod to give motion to valve lever L will strike the loose ring
on top of rubber collar before the piston comes in contact with the end of cylinder,
This gives the workman notice to turn the feed screw M to prevent a breakage.
On side of cradle is a groove in which to carry machine down the length of feed
screw M to give chisel a length of feed, Whilst the screw N on angle iron frame O
is carrying the machine backwards and forwards, an oscillating motion may be
obtained, by means of a joint T underneath to suit the purpose. For road cutting
either coal or drift-there is a carriage with a perpendicular bar P on which is a
rack motion Q with pinion R. This pinion is worked by a screw S so that machine
may work in any position required and if necessary oscillating at the same time,
by means of joint on machine to suit the purpose, The centre bar should be made
fast to roof or sides to steady machine. The rack Q will carry machine up or down
for cutting sides or along bottom or top as the case may require, and at the same
will oscillate when required.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
(1.) That machine will travel on angle iron frame O strike and oscillate at one
and the same time.

side if required, and bent tool G for similar purpose, also straight tool F for cutting
Dear centre.
(3.) The open part of machine in which the grooves in piston rod work upon the
feather or key in guide block brass, to keep the cutter in its proper position, the
groove not travelling into cylinder, so that air or steam cannot escape.
(4.) Enabling workman to see the motion of valve lever, so as to be able to
adjust it when required.
(5.) The loose ring J and rubber collar in guide block which gives the workman
notice to turn the feed screw in order to prevent a breakage.
(6.) The rack motion on perpendicular bar P and screw with pinion R for
carrying machine up and down, or backwards and forwards, so that it may cut on
any side, and oscillate at the same time if required.
