Improvements in Machinery or Apparatus for Drilling or Boring
Rock and other Substances.
I JAMES KER GULLAND of No. 6ª Victoria Street, in the City of Westminster,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to machinery or apparatus for drilling or boring
rock or other hard substances. According to one arrangement I mount upon a
suitable carriage a shaft having thereon a worm wheel and an eccentric which
may advantageously be cast in one and be free to rotate upon the shaft the worm
wheel being formed or provided with a part clutch the other part of which is move-
able lengthwise of the shaft but prevented by a feather from rotating independently
thereof. Keyed upon the shaft is a drum or barrel the arrangement being such that
according to whether the clutch is in gear or out of gear the shaft and drum or
barrel can be caused to rotate or not with the worn wheel and eccentric or when the
latter are not being driven the drum under control of a brake can be allowed to rotate
independently of the worm wheel and eccentric for the purpose of lowering drilling
or boring rods or bars. The worm wheel is in gear with a worm on another shaft
that can be driven by any suitable means, it may be by an oscillating or other engine
mounted on the same carriage or by belt driven from a portable engine or other
source. Upon the same carriage is placed a pump worked by an eccentric on the
same shaft that carries the barrel or drum. The pump is or may be provided
with a bib cock so that if it be desired to drive the barrel or drum without pumping
water simply air will be drawn in and forced out of the pump cylinder. The barrel
or drum is for the purpose of lifting and lowering the boring rods and the pump
is for the purpose of supplying water for cooling and lubricating the drilling or
boring tool and removing the debris from the bore hole.
To adapt a machine for drilling or boring either vertically horizontally or at other
angle as may be from time to time required and which may be used for drilling or

page_text: boring in a tunnel or heading I mount the drill head and pump (which may be ver-
tically arranged) with suitable driving shaft and gear and with or without an engine
upon a frame adapted to swivel upon a suitable carriage bolts or fastenings being
provided whereby the machine can be secured upon the said carriage in any position
to which it may have been turned for the purpose of drilling or boring a hole in any
particular direction. Conveniently a pair of oscillating cylinders may be mounted
upon the swivelling frame but if there be no engine thereon the machine may be
connected from an independent engine by a rope or belt. Conveniently the drill bead
may be operated from one end of the crank or other shaft and the pump from the
other.
For the purpose of guiding supporting and steadying the drilling or boring rods or
bars I provide them with rings or collars having an internal diameter to slide freely
upon the boring rod and an external diameter almost equal to that of the bore hole such
rings or collars being either loose upon the boring rod so that longitudinal movement
of the rod independent of the ring or collar may take place or relative endwise move-
ment may be prevented by arranging the ring guides or bearings between other collars
fixed on the boring rods or bars. The said guide rings collars or bearings are
provided with suitable holes for the passage of water and debris from the drilling
or boring tool.

Improvements in Machinery or Apparatus for Drilling or Boring
Rock and other Substances.
I, JAMES KER GULLAND, of No. 6ª Victoria Street, in the City of Wesminster,
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:-
This invention has reference to machinery or apparatus for drilling or boring rock
or other hard substances.
According to one arrangement I mount upon a suitable carriage, a shaft having
thereon a worm wheel and an eccentric which may advantageously be cast in one and
be free to rotate upon the shaft, the worm wheel being formed or provided with a part
clutch the other part of which is moveable lengthwise of the shaft but prevented by a
feather from rotating independently thereof.
Keyed upon the shaft is a drum or barrel the arrangement being such that according
to whether the clutch is in gear or out of gear the shaft and drum or barrel can be
caused to rotate or not with the worm wheel and eccentric, or when the latter are not
being driven the drum under control of a brake can be allowed to rotate inde-
pendently of the worm wheel and eccentric for the purpose of lowering drilling or
boring rods or bars.
The worm wheel is in gear with a worm on another shaft that can be driven by any
suitable means, it may be by an oscillating or other engine mounted on the same
carriage, or by belt driven from a portable engine, or other source. Upon the same
carriage is placed a pump worked by an eccentric on the same shaft that carries the
barrel or drum.
The pump is or may be provided with a bib cock so that if it be desired to drive the
barrel or drum without pumping water simply air will be drawn in and forced out of
the pump cylinder. The barrel or drum is for the purpose of lifting and lowering
the boring rods and the pump is for the purpose of supplying water for cooling
and lubricating the drilling or boring tool and removing the debris from the bore
hole.
Figs. 1, 1 sheets 1 and 2 represent in side elevation an apparatus according to this
invention, complete with steam engine and steam boiler.
Figs. 2, 2 sheets 3 and 4 represent the same in plan, and
Fig. 3 is an end view.
1 is a carriage provided with axles 2, 2, and wheels 3 on which it runs.
Upon this carriage is mounted an engine, comprising two oscillating cylinders 4, 4,
which drive on to a common crank pin on the crankshaft 5. These cylinders each take
team through one trunnion and exhaust it through the other; the distribution is
ffected by a valve, at 6 operated by the oscillation of the cylinder.
The steam is obtained from a boiler 9, Figs. 1ª 2" which is here shewn mounted on
wheels so that it can follow the drilling apparatus. The crankshaft 5 is prolonged

page_text: 5
worm 11. This worm
towards the left (Fig. 1) and carries a flywheel 10 and a
engages with a worm wheel 12 which is attached to or formed in one with an
eccentric 13.
The wheel and the eccentric are loose on the shaft 14 which revolves in the
bearings 15, 15, on the carriage 1.
On the face of the wormwheel is a part clutch capable of being engaged by the
corresponding part clutch 16.
This latter is connected to the shaft by a feather key, and can be slidden along it by
a lever not shewn when it is desired to put it in or out of engagement with the part
clutch in the worm wheel. Upon the shaft 14 there is also keyed a barrel 17, provided
with a brake pulley 18, and a brake band and lever not shewn in the drawings. The
eccentric 13 drives a pump 19 provided with a suction pipe 20, a weighted escape
valve 21, and an air vessel 22. The valve 21 serves when open as a bypass, and
when it is unloaded it allows the water to flow back to the suction tank.
At the right hand of the crankshaft 5 there is a pair of bevil wheels which drive
the drill spindle 23.
The hearings in which the spindle revolves are attached to a head or face plate 24
bolted to the engine frame.
This head can be rotated around the crankshaft as a centre so as to place the drill
in a vertical, inclined or horizontal position. The drill spindle with its driving and
feeding appliances form no part of my invention and it is not necessary to describe it,
as any convenient arrangement of drill spindle may be adopted. As long as the
engine is running the worm wheel 12 and eccentric 13 are kept in rotation, but until
the clutch 16 is put into engagement, the barrel 17 is disconnected from the engine.
As soon, however, as the clutch is put into gear the barrel commences to rotate, and
to wind up the rope or chain connected to the drill rods. When the clutch is again
machine
put out of gear the drill rods can be lowered by the brake 18. To adapt a
for drilling or boring either vertically, horizontally, or at other angle as may be from
time to time required, and which may be used for drilling or boring in a tunnel or
heading, I mount the drill head and pump (which may be vertically arranged) with
suitable driving shaft and gear and with or without an engine upon a frame adapted
to swivel upon a suitable carriage, bolts or fastenings being provided whereby the
machine can be secured upon the said carriage in any position to which it may
have been turned for the purpose of drilling or boring a hole in any particular
direction. Conveniently a pair of oscillating cylinders may be mounted upon the
swivelling frame but if there be no engine thereon the machine may be connected
with an independent engine by a rope or belt. Conveniently the drill head may
be operated from one end of the crank or other shaft and the pump from the other.
Fig. 4 is an end view of the frame of a modified form of apparatus according to
this part of my invention.
Fig. 5 is a plan thereof.
Fig. 6 is an end view, similar to fig. 1, of the complete apparatus arranged to be
driven by an engine having a pair of oscillating cylinders.
Fig. 7 is a side view of the same.
1 is a
on which it runs.
(These wheels
carriage provided with axles 2 and wheels
are omitted in figs. 4 and 5). Upon the carriage is mounted a frame 25 capable of
being rotated about its vertical axis, and of being secured to the carriage by
Tbolts 26, 26 the heads of which engage with a circular T groove 27 in the table 28
on the top of the carriage 1.
The groove 27 has an outlet or offset (shewn in figs. 4 and 5) by which the bolts ar
introduced into it. When these bolts are slackened, the entire frame 25 with it
attachments can be rotated on the carriage. Upon the frame is mounted a pair o
oscillating cylinders 4, 4 driving a crankshaft 5. The left hand end of the shaf
carries a flywheel 10, and by means of a crank pin 29, and connecting rod 3
works a pump 19 provided with an air vessel 22. The opposite end of this sha
drives the drill spindle 23 through bevil wheels and a swivelling arrangement a
already referred to in describing figs. 1, 2 and 3. For the purpose of guiding

page_text: supporting, and steadying the drilling or boring rods or bars, 1 provide them with
rings or collars having au internal diameter such as to slide freely upon the boring
rod and an external diameter almost equal to that of the bore hole, such rings or
collars being either loose upon the boring rod so that longitudinal movement of
the rod independent of the ring or collar may take place, or relative endwise
movement may be prevented by arranging the ring guides, or bearings between
other collars fixed on the boring rods or bars. The said guide rings, collars, or
bearings are provided with suitable holes for the passage of water and debris from the
drilling or boring tool.
Fig. 8 and 9 show such a ring or collar, and
Fig. 10 shews a modified form of the same.
31 is a drill rod, and upon it there is loosely slipped.a ring or collar 32 slightly less*
in external diameter than the bore hole 33.
Holes 34, 34 are formed through the collar for the passage of water and debris, or
slots 35, 35 (fig. 10) are formed in the periphery for the same purpose.
The collar 32 is made to travel in and out of the bore hole 33 by fixed collars 36.
These latter collars may be arranged to allow the collar 32 considerable range of
movement, or one may be placed at each side, thus preventing all endwise movement.
A coupling 37 may sometimes take the place of a collar 36.
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 1. claim in
apparatus for drilling and boring rock and other substances is :-
1. The combination, upon a carriage, of a pump and a rope drum fitted with a
friction brake, together with a bye pass valve or its equivalent, and a clutch by which
the pump and the drum may be respectively put in and out of action at will
without stopping the prime mover by which they are both driven, substantially as
described and illustrated.
2. A frame mounted upon a travelling carriage in such a way that it may be
swivelled in any direction about its vertical axis, and fitted with a drill head, and a
pump driven from a shaft operated by the prime mover substantially as described and
illustrated and for the purposes specified.
3. The combination with a drilling or boring rod, of rings or collars capable of
sliding freely on the said rod, and of entering the bore hole, the said rings or
collars being for the purpose of guiding the rod in the hole, and being provided with
holes or slots for the passage of water and debris, substantially as described.
4. The improved apparatus for drilling or boring rock or other substances,
substantially as described with reference respectively to Figs. 1, 1, 2, 2ª and 3, and
to Figs. 4, 5, 6 and 7 of the drawings.
