page_text: 1, REGINALD STANLEY, of Nuneaton Colliery, Nuneaton, in the county of
Warwick, Brick and Tile Manufacturer and Colliery Proprietor, do hereby declare
the nature of this invention to be as follows:-
This invention relates to further improvements in that class of machine or apparatus
for boring, tunnelling, or helping to make headings, passages, road- or air- ways in
coal, marl, stone, and other substances described in the Specification of former
Letters Patent granted to me dated January 10th 1885, No. 335, the said boring
machines being fixed in position, while by means of revolving arms and cutters an
annular groove is cut in the face of the heading, the machine when the arms and
cutters have penetrated or been extended the required distance, being released and
again advanced and fixed in position for another cutting.
My present improvements have for object to provide means for the more easy and
rapid advancement of the machine between the periods of fixing and cutting, and a
more rapid and accurate manner of fixing the inachine preparatory to making a
fresh cutting.
For this purpose instead of running the machine forward on rails, the laying and
regulating of which involves a considerable expenditure of time, I mount the whole
machine on central wheels or rollers which are either spiked, roughened, or otherwise
and run on the floor of the heading. I also provide a side or steadying wheel or
wheels which keeps or keep the machine upright when being run forward and in
proper position for fixing it preparatory to and after it is fixed for cutting a fresh
distance forward in the annular groove. By means of suitable engines and gearing
attached to the machine and driven by compressed air or other suitable means, and
acting upon wheels or collars that are advantageously spiked or roughened and which
work into or against the circumference of the heading I cause the whole to be
advanced automatically.
I also fix shields or guards in front and at the side of the wheels or rollers that
work on the floor of the heading to prevent the coal and debris getting under the
said wheels or rollers

page_text: I make the threaded block or nut in which works the central or cutter shaft so
that it can open on hinges, the said block being attached to the machine and held
closed when required by a clip or any other suitable means.
I also provide means whereby the back wheel or roller carrying the machine and
running on the floor of the heading can be raised or lowered to alter the direction in
which it is required that the arms and cutters shall work.
The machine is fixed and held in position while cutting the annular groove by the
wheels or rollers on which it is carried, by screw pins screwing into the roof or
sides of the heading or by wheels or rollers working against the roof or sides of the
heading The side screw pins or wheels or rollers are also used to guide the cutting
of the annular groove by changing the direction of the machine either to the right
or left hand as may be desired.
Means are provided whereby the direction of both the front and back wheels or
rollers carrying the machine and working on the floor of the heading can be altered
for the purpose of guiding or directing the machine when being run forward and for
providing against the twist that sometimes takes place when operating on hard
substances.
By this improved construction it will be obvious that a great saving will be effected
in the time occupied in moving the machine forward between each cutting operation,
and that the machine can be more readily and accurately placed in proper position to
allow of it being fixed ready for advancing to the next cutting, the central wheels or
rollers working on the floor of the heading, and the side wheel or wheels, serving not
only to carry, steady, and guide the machine but to hold it in position while the
cutting operation is being performed.
A much smaller expenditure of labour is required by this system of moving
forward and fixing the machine than has hitherto been the case.

page_text: I, REGINALD STANLEY, of Nuneaton Colliery, Nuneaton, in the county of Warwick,
Brick and Tile Manufacturer, and Colliery Proprietor, 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:-
This invention relates to improvements in that class of machine or apparatus for
boring, tunnelling, or helping to make headings, passages, road-ways or air-ways in
coal, marl, stone and other substances described in the Specification of former
Letters Patent granted to me dated January 10th 1885, No. 335, the said boring
machines being fixed in position, while by means of revolving arms and cutters an
annular groove is cut in the face of the heading, the machine when the arms and
cutters have penetrated or been extended the required distance, being released and
again advanced and fixed in position for another cutting.
My present improvements have for object to provide means for the more easy and
rapid advancement of the machine between the periods of fixing and cutting, and a
more rapid and accurate manner of fixing the machine preparatory to making a fresh
cutting.
In order to enable my invention to be fully understood I will describe how it can
be carried into practice by reference to the accompanying drawing in which figure 1
represents a side elevation and figure 2 a rear elevation of my improved boring
machine at work. Similar letters in all the figures represent similar or corresponding
parts.
According to my present improvements instead of running the machine forward
on rails, as in my said former Patent the laying and regulating of which rails
involves a considerable expenditure of time, I mount the whole machine on central
wheels or rollers A A which run directly on the floor of the heading and which work
tandem fashion in the centre of the floor as shown in figure 2.
The
I also provide a side or steadying wheel B (or wheels) which keeps the machine
upright when being run forward and in proper position for fixing it preparatory to
and after it is fixed for cutting a fresh distance forward in the annular groove.
wheel B is regulated by means of a right- and left-hand screw pin C (or otherwise)
so as to be withdrawn or lengthened thus serving to regulate the position of the
machine in the heading.
I generally have both of the central carrying wheels A to run loose in their
bearings, but sometimes, by means of suitable engines and gearing attached to the
machine and driven by compressed air or other suitable means and acting upon the
central front wheel or roller A as shown (or upon another wheel or wheels) that is
advantageously spiked or roughened and which works into or against the circum-
ference of the heading after throwing the central shaft with its arms and cutters out
of gear by sliding the small spur wheel J along the crank shaft out of gear.

page_text: cause the whole to be advanced automatically. The front wheel or roller A is
driven from the engine crank shaft D by means of a vertical shaft E and bevel
wheels F, G which can be thrown in and out of gear; a worm H on the shaft E
gears with a cog-wheel I on the axle a¹ of the front central carrying wheel A as
shown. When this gearing is set in motion and the spur pinion J on the crank
shaft D, that causes the central shaft a to revolve, is thrown out of gear, the front
central carrying wheel A is caused to revolve and bite on or into the floor of the
heading, and causes, or helps to cause, the machine or that part of the machine that
moves forwards between each cutting operation to advance as required.
In my said former Patent the central screw-threaded shaft a is described as
working in a correspondingly screw-threaded block or nut which is removable from
the frame of the machine and which is rotated on the shaft a according as it is
required to cause it to advance or retire.
According to my present improvements I make the screw-threaded nut or
block in which works the central or cutting shaft a in two parts so that it can open
on a hinge K attached to the frame of the machine and held closed when required
by a clip L (or by other suitable means) so that when the block is closed and
secured by the clip L it causes the shaft a with the arms b, b and cutters c c attached
thereto to advance or retire according to the direction in which the shaft is caused to
revolve and when, the cutters having entered the heading to the proper depth, it is
required to move the frame and its attachments forward on the shaft the clip Lis
removed and the divided block or nut is thrown open on its hinge K when the
shaft a can pass freely through the nut without revolving.
I also provide means whereby the back or front of the machine can be raised or
lowered on the wheels or rollers A, A carrying the same and running on the floor of
the heading in order to alter the direction in which it is required that the arms b, b
and cutters c, c shall work.
For this purpose the central carrying wheels or rollers A, A have their axles a², a¹
working in bearings M, M which can by means of set screws a, a or other means be
moved up and down in boxes or brackets N, N attached to the frame of the machine
at the front and back as shown or at the back only, the set screws a passing
through the top of the boxes or brackets N, N and working on or against the
bearings M, M. that contain the axles a', a of the central carrying wheels A A.
The machine is fixed and held in position while cutting the annular groove by the
wheels or rollers A A on which it is carried and by screw pins zz screwing into
the roof or sides of the heading as shown or by wheels or rollers working against the
roof or sides of the heading. The side screw pins ea or the side wheel or roller B
is also used to change the direction of or guide the machine to the right or left hand
as may be desired and thereby alter the direction in which the annular groove is to be
cut. The back carrying wheel A I prefer to make smooth on its face so as to be
easily moved to the right- or left-hand as may be required by the action of the back
telescopic screw pins.
By this improved construction it will be obvious that a great saving will be effected
in the time occupied in moving the machine forward between each cutting operation,
and that the machine with the central carrying wheels or rollers working in the
centre of the floor of the beading can be more readily and accurately placed in
the exact position to allow of it being fixed ready for advancing the next cutting in the
direction it is required to cut. The central wheels or rollers working on the floor of
the heading, and the side wheel or wheels serve not only to carry, steady and guide
the machine but to hold it in position while the cutting operation is being performed.
A much smaller expenditure of labour is required by this system of moving
forward and fixing the machine than has hitherto been the case.
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. In a machine for boring or assisting to make passages, headings, and the like,

page_text: in coal or other substances, which machine or part of which machine, is fixed in the
heading during the process of cutting, the combination of a central revolving screw-
threaded shaft, having arms and cutters attached, with centrally placed wheels
carrying the machine and working directly on the floor of the passage or heading.
2. In a machine for boring or assisting to make passages or headings in coal, marl
or other substances, which machine or part of which machine is fixed in the heading
during the process of cutting; the use of a carrying wheel or wheels spiked, ribbed,
or roughened for biting into or catching onto the floor of the heading, and driven by
means of suitable gearing from the crank shaft of the engine which when the
cutting part of the machinery is thrown out of gear is used for advancing or
assisting to advance the machine between the cutting operations, substantially as
hereinbefore described.
3. In a machine for boring or assisting to make passages or headings in coal, marl,
or other substances, the said machine consisting of a frame carrying actuating
machinery and a central screw-threaded shaft, the use of a divided screw-threaded
block attached to the machine through which block when closed, the central screw-
threaded shaft revolves and is caused to advance and which when opened allows the
said shaft to retire without being revolved as herein before described.
