PROVISIONAL SPECIFICATION.
Improved Apparatus for "Heading" and "Holeing" Coal and other
Minerals.
We MILES SETTLE Colliery Proprietor and WILLIAM SETTLE Assistant Mining
Engineer both of Darcy Lever near Bolton in the County of Lancaster do hereby
declare the nature of this invention to be as follows:-
"
The object of this invention is to construct an apparatus for "beading" and
holeing" coal or other minerals, the said apparatus being more inexpensive and
mupler than any at present in austage I mount an electro-motor connected by wires to
a dynamo; or other generator of electricity, at the mouth of the coal pit or mine.
The armature shaft of the electro-motor actuates a second shaft by suitable gearing
and this shaft actuates a horizontal disc or wheel provided with a series of cutters of
suitable shape. I prefer to make use of cutters of two kinds, namely with single
and double points or edges arranged alternately and in such a manner that the single
cutters work in the space left between the two points or edges of the double ones.
The cutter-disc or wheel will thus clear itself as it cuts the coal or mineral.
The trolley or carriage is so made that it can turn beneath the cutter-disc and the
electro-motor without altering the position of these latter, with regard to the coal, and
thus the machine can be moved on rails running either at right angles to or parallel
with the electro-motor shaft, and consequently the apparatus can be used either for
"holeing" or undercutting a broad surface of coal or other mineral or for "heading"
or cutting a headway into the same.

COMPLETE SPECIFICATION.
Improved Apparatus for Heading and Holeing Coal and other
Minerals.
We MILES SETTLE, Colliery Proprietor and WILLIAM SETTLE, Assistant Mining
Engineer both of Darcy Lever near Bolton in the County of Lancaster, 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:-
The object of this invention is to construct an apparatus for heading and holeing
coal or other minerals, the said apparatus being more inexpensive than any at present
in use.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 is a side elevation (partly in section) of our improved apparatus the electro
motor being drawn in dotted lines and
Fig. 2 a plan view of the same.
Upon a suitable trolley or carriage a we mount a bed plate b capable of turning
horizontally upon a vertical stud or pivot c in a socket d carried by the trolley. Upon
this bed plate is fixed an electro-motor (shown by the dotted lines) which is connected
by wires to a dynamo or other generator of electricity placed at the mouth of the coal
pit or mine, or in any other convenient situation on the surface or at the bottom of
the pit or mine.

page_text: Upon the armature shafte of the electro motor is fixed a spur pinion g gearing with
a spur wheel h which works through a hole or slot in the bed plate b. This wheel h
actuates (either directly or indirectly) a crown or similar wheel & fixed to or cast
with the horizontal disc or wheel which is provided on the edge with a series of
cutters m m³ of suitable shape. We prefer to make use of cutters of two kinds,
namely with single and double points arranged alternately as shown so that the single
cutters m work in the space left between the two points or edges of the double ones m¹.
The cutter or wheel will thus clear itself as it cuts the coal or mineral.
The trolley or carriage a is so arranged that the whole apparatus can be turned
round upon the stud or pivot c carrying the electro motor and cutting wheel with it
so that the position of the latter with regard to the face of the coal can be altered
without altering the position of the trolley upon the rails; and the bed plate bis
provided with holes i into which pins can be dropped so as to secure it either at right
angles to or parallel with the face of the coal, and consequently the apparatus can be
used either for "holeing" or undercutting a broad surface of coal or other mineral or
for "heading" or cutting a head way into the same.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The combination with a trolley or carriage running upon rails, of a bed plate pivoted
thereon so as to be adjustable horizontally and carrying a horizontal dise provided
with cutters round the circumference, and an electro motor and gearing for giving a
rotary motion to the said cutter disc substantially as hereinbefore described and
illustrated by the drawings annexed.
