Complete Specification Left, 4th May, 1897-Accepted, 5th June, 1897
I, PHILIP ARTHUR NEWTON of The Office for Patents, 6 Bream's Buildings
Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention to be as follows:-
This invention relates to channelling machines of the class commonly known as
"track channellers," such machines comprising a carriage mounted to run on a
track, and on which is secured a rock drill embodying a working cylinder and a
piston reciprocating rapidly therein, and having a drill or bit secured upon its
piston-rod. The object of this invention is to adapt such a machine to the
production of what are known in quarrying operations as "under-cut channels,"
having generally a horizontal direction, or a direction only deviating from the
horizontal, as may be desirable, to permit the bits to follow a dipping or pitching
vein.
The invention consists in certain combinations of parts, whereby the machine is
adapted to the cutting of such channels as are hereinabove mentioned.
Mounted on a wheeled carriage, which is propelled on a railway by any approved
motor, is a "drill back," which overlies the side of the carriage, and is capable of
adjustment upward and downward relatively to the carriage, to place the drill
cylinder and bit holder in horizontal or inclined positions.
The drill-back consists of a frame carrying the working cylinder fitted with a
piston for carrying and operating the bit. The frame is attached to the carriage
at one side by means of a pivotal connection, consisting of an upright bracket
bolted to the carriage, and having pivotted to it a hanger or hinged piece which is
made fast to the drill-back.
At the other side of the carriage is a clamping connection consisting of two
slotted brackets, connected together by an adjustable clamping screw, and capable
of sliding the one over the other, the one being made fast to the adjustable frame,
and the other being secured by a clamping screw to the carriage. By this means
the adjustment, whether vertically or horizontally, given to the frame, will be
firmly maintained during the working of the bit in the desired direction.
From the foregoing description it will be understood that the said drill back will
completely overhang the carriage, and will lie across, and very close to the track,
and may be adjusted vertically to a horizontal position, or to any inclination, as
may be desired, and that it may be further adjusted horizontally to a position
parallel with the axles of the carriage wheels, or more or less oblique thereto, as
may be desired.
The whole of the drilling apparatus, consisting of the drill-back, drill cylinder,
bit stock, and bits, together with the hangers and standards, may be made
reversible from one end of the carriage to the other, or two separate drilling
apparatuses may be provided, one for each end of the carriage, and each

page_text: attached thereto by its own set of hangers and standards, such as hereinabove
described.
It is an important feature of this invention, that the drilling apparatus, by
reason of its drill back or frame entirely overhanging the end of the carriage, with
the drill cylinder across the track, instead of being arranged to overhang one of
the sides of the carriage parallel with the track, as is common in track channellers,
permits the cutting of a horizontal channel nearly on a level with the track on
which the carriage runs, or a slightly inclined channel, as low as, or even lower
than, the said track, and also permits the cutting of the channel close up into
corners.

Improvements in Channelling Machines.
I PHILIP ARTHUR NEWTON of The Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, 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 channelling machines of the class commonly known as
"track channellers," such machines comprising a carriage mounted to run on a
track, and on which is secured a rock-drill embodying a cylinder and a piston
reciprocating rapidly therein, and having a drill or bit secured upon its piston rod.
The object of this invention is to adapt such a machine to the production of what
are known in quarrying operations as "under-cut channels," having generally a
horizontal direction, or a direction only deviating from the horizontal, as may be
desirable, to permit the bits to follow a dipping or pitching vein.
The invention consists in certain combinations hereinafter described and claimed,
whereby the machine is adapted to the cutting of such channels as are hereinabove
mentioned.
Fig. 1 represents an elevation of an undercutting track channeller embodying
this invention.
Fig. 2 is an elevation at right angles to that shown in Fig. 1, showing only those
parts of the machine directly involved in this invention.
Fig. 3 is a plan view corresponding with Fig. 2;
Fig. 4 an elevation corresponding with Fig. 1, but including only the parts shown
in Figs. 2 and 3.
Fig. 5 represents a vertical section taken in the line -5 of Fig. 3;
Fig. 6 a vertical section taken in the line 6-6 of Fig. 3.
A designates the carriage of the machine, represented as consisting of a
quadrangular frame mounted on wheels B B, to run on a light rail track C C
conveniently laid for the purpose. To either end of this carriage, what is known
as the "drill-back," consisting of the frame which carries the drill cylinder E and
its immediate appurtenances, is attached in such manner that the said drill-back
will completely overhang the carriage, as shown in Figs. 2, 5, and 6, and will lie
across and very close to the track, and may be adjusted vertically to a horizontal
position, as shown in Fig. 4, or to such inclination as may be desired, as illustrated
in Fig. 1, and that it may be further adjusted horizontally, to a position parallel
with the axles B' of the wheels B, or more or less oblique thereto, as may be
desired.

page_text: For the purpose of attaching the drill-back D to the carriage, to provide for the
adjustments hereinabove mentioned, the said drill-back has attached to it, on that
side which comes next the carriage, two hangers F and G, H, through which it is
bolted by screw bolts a and b to two standards F1 and G₁ erected upon the
carriage A, near one end thereof, but at opposite sides thereof, as shown in Figs. 3
and 4.
The hanger G, H at the rear end of the drill-back D, consists of two
members G and H, united by a hinge c, d, e, the upright pivotal connection e
of which is situated very near the rear end of the drill-back. The member G is
rigidly bolted at f,f (Fig. 4), to the drill-back, and the member H is bolted to the
standard G by a bolt a, which serves as a pivot upon which the drill-back, with
the cylinder E, the reciprocating bit holder E', and bits E2, may be adjusted
vertically to a horizontal position, as shown in Fig. 4, or to an inclined position, as
shown in Fig. 1. The standard G₁ is bolted rigidly to the carriage by bolts 9, 9,
as shown in Figs. 2 and 3, the adjustments at the rear end of the drill-back being
made on the pivots a and e. The hanger F, at the front end of the drill-back or
cylinder frame D, is bolted rigidly thereto at hh. This hanger consists of a
simple upright, in which is an arc-formed slot i (see Figs. 1, 4 and 5), for the
reception of the bolt b, which fits snugly in a hole in the standard F', the said slot
being concentric with the pivot a, to permit the upward and downward adjustment
of the front end of the drill-back. This adjustment is secured by screwing up the
bolts a and b. The hinge, c, d, e, provides for the adjustment of the drill-back
with its drill cylinder E, in a horizontal direction, to a position parallel with the
axles B', and at right angles to the track, or to a position oblique thereto, and to
permit this adjustment, and provide for securing the drill-back at the proper angle
transverse to the carriage A and track when so adjusted, the base of the
standard F, which rests on the top of the carriage, and is secured to the latter
by a bolt j, has provided in it, as shown in Figs. 3 and 5, for the reception of said
bolt, a slot k, which is in the form of an arc concentric with the pivote of the
hinge.
The carriage A is intended to be furnished with a steam engine or other motor,
geared in any suitable manner with one of its axles for the purpose of moving it
upon the track in a direction in which the channel is to run. As such motors and
gearing are used on channelling machines, it will be sufficient here to say, that
these may be such as are described in English Letters Patent No. 7606, dated 7th
1889, or No. 12894, dated July 3rd 1894.
The whole of the drilling apparatus, consisting of the drill-back, drill cylinder,
bit-stock, and bits, together with the hangers F and G, H, and standards Fi
and G', may be made reversible from one end of the carriage to the other, or two
separate drilling apparatuses may be provided, one for each end of the carriage,
and each attached thereto by its own set of hangers and standards, such as
hereinabove described.
It is an important feature of this invention, that the drilling apparatus, by
reason of its drill-back or frame entirely overhanging the end of the carriage with
the drill cylinder across the track, instead of being arranged to overhang one of
the sides of the carriage parallel with the track, as is common in track channellers,
permits the cutting of a horizontal channel nearly on a level with the track on
which the carriage runs, or a slightly inclined channel, as low as, or even lower
than, the said track, and also permits the cutting of the channel close up into
corners. Another important feature is the adjustments provided for the setting of
the cylinder and bits, either square with the line of the channel, or at an oblique
angle thereto.
Having now particularly described and ascertained the nature of the said inveu-
tion and in what manner the same is to be performed, as communicated to me
from abroad, I declare that what I claim is :-
1. In a channelling machine. the combination of a carriage, a drilling apparatus

page_text: comprising a drill cylinder, and a reciprocating bit holder and bit, and a frame for
said cylinder attached to the said carriage at one end thereof, and overlapping the
said end, said frame being adjustable upward and downward relatively to the
carriage, to place the drill cylinder and bit holder in horizontal or inclined
positions crosswise of, and beyond the end of, the carriage, substantially as herein
described.
2. In a channelling machine, the combination of a wheeled carriage, a drill
cylinder, and a reciprocating bit holder and bit, and a frame for said cylinder
attached to the said carriage at one end thereof, and overlapping the said end
beyond and outside of the carriage wheels, the said frame being adjustable upward
and downward relatively to the carriage, to place the drill cylinder in horizontal
or inclined positions crosswise of the carriage and outside of its wheels,
substantially as herein described.
3. In a channelling machine, the combination of a wheeled carriage,
a drill
cylinder, and a reciprocating bit holder and bit, and a frame for said cylinder

beyond the carriage wheels, the said frame being adjustable horizontally in
different positions beyond the carriage wheels, to place the drill cylinder at
different angles to the axes of the said wheels, substantially as herein described.
4. In a channelling machine, the combination of a carriage, a drilling apparatus,
comprising a drill cylinder, and a bit holder and bit, and a frame for said cylinder
attached to the carriage at one end thereof, and overlapping the said end, sail
frame being adjustable both vertically and horizontally, to place the cylinder and
bit holder at various inclinations and at various angles transverse to the carriage
beyond the end thereof, substantially as herein described.
5. In a channelling machine, the combination of a carriage, a drilling apparatus,
comprising a drill cylinder and a bit holder and bit arranged across and
overhanging one end of said carriage, an upright pivotal connection between said
frame and one side of the carriage, and a horizontally movable clamping connection
between the said frame and the other side of the carriage, the said pivotal and
clamping connections providing for the horizontal adjustment of the said frame at
different angles transverse to the carriage, substantially as herein described.
6. The combination with the carriage and the drill-back arranged beyond one
end of the carriage, of a hanger composed of two members which have an
upright pivotal connection, and one of which is affixed to the drill-back, a standard
affixed to the carriage, and a horizontal pivotal connection between the other of
said members and said standard, substantially as and for the purpose herein
described.
7. The combination with the carriage and the drill-back, of an upright pivotal
connection between the drill-back and the carriage, at or near one side and one end
of the latter, a hanger affixed to the drill-back at or near the same end and the
other side of the carriage, an adjustable standard having a curved slotted base on
said other side of the carriage, and bolts for adjustably securing said standard to
the carriage, and attaching said hanger to said standard, substantially as herein
described.
