PROVISIONAL SPECIFICATION,
Improvements in Machinery or Apparatus for Drilling, Boring, and
Internally Screwing or Tapping Holes in Metal Plates.
We, Messrs. HULSE & Co., LTD., of Ordsal Works, Salford, in the County of
Lancaster, Engineers, and HENRY BATES, of the same place, Managing Director
of the said Company, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machinery or apparatus for drilling, boring and
internally screwing or tapping holes in metal plates such for example as armour
plates whether curved or flat.
A machine suitable for these purposes according to this invention comprises
a bed made in one or more parts upon which is or are arranged one or more
longitudinally sliding carriages. Upon each sliding carriage is mounted a
vertical frame or standard, (hereinafter referred to as a standard), provided
with a horizontal arm projecting at right angles to the bed of the machine. The
standard is adapted to swivel on and be secured to the longitudinally sliding
carriage at any angle in a horizontal plane. Each sliding carriage with its
standard can be moved along the bed by means of one or more non-rotatable
screws arranged inside the bed and provided with rotatable nuts. Upon the
projecting arm of each standard and arranged to traverse horizontally to and
fro thereon, is mounted a transverse slide provided with a drilling headstock,
and with suitable mechanism whereby reversible rotary motion can be imparted
to the spindle of the drilling headstock from a shaft arranged along the pro-
jecting arm of the standard. It will be obvious that the spindle can be provided
with a screwing tool instead of a drill or boring tool when required.
The drilling headstock is arranged to swivel on and be secured to the transverse
slide at any angle in the transverse vertical plane of the slide.
A baseplate extending along the front of the machine to which the work may
be secured may be provided when required.
Suitable arrangements of mechanism are provided for imparting, either by
hand or power, a vertical traverse up or down to the drilling spindle; a transverse
traverse along the projecting arm, to the transverse slide and drilling head-
stock;
and a longitudinal movement, along the bed of the machine, to the
sliding carriage or carriages.
Rotary motion to the drilling spindle on each standard is obtained through
suitable gearing from one or more longitudinal shafts running lengthwise of
the machine, and driven by an independent belt-driven headstock or an electric
motor, placed, when two are required, advantageously at opposite ends of the
bed. For example one shaft may drive two spindles; or each spindle may be
driven by its own shaft. Or each sliding carriage with its standard and drilling
headstock may be driven by its own electric motor, means being provided for
suitably varying the speed. "In this case the motor may be carried by the sliding

Improvements in Machinery or Apparatus for Drilling, Boring, and
Internally Screwing or Tapping Holes in Metal Plates.
We, Messrs. HULSE & Co., LTD., of Ordsal Works, Salford, in the County of
Lancaster, Engineers, and HENRY BATES, of the same place, Managing Director
of the said Company, 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 machinery, or apparatus, for drilling, boring, and
internally screwing, or tapping holes in metal plates, such, for example, as
armour plates, whether curved or flat.
A machine suitable for these purposes is shewn in the accompanying drawings
wherein,
Fig. 1 is a plan,
Fig. 2 an end elevation;
Fig. 3 a sectional elevation on the line A-B, Fig. 1; and
Fig. 4 a front view of the machine.
The machine comprises a bed 1 made in one or more parts upon which is,
or are, arranged one or more longitudinally sliding carriages 2, 3. Upon each
of the sliding carriages 2, 3, is mounted a vertical frame or standard 4, 5, (herein-
after referred to as a standard). provided with a horizontal arm 6, 7, projecting
at right angles to the bed 1 of the machine. Each standard 4, 5 is adapted
to swivel on and be secured to its longitudinally sliding carriage 2, 3 at any
angle in a horizontal plane. Each sliding carriage 2, 3, with its standard 4, 5
can be moved along the bed 1 by means of a non-rotatable screw 8 arranged
inside the bed each carriage being provided with a rotatable nut 9 shewn in
section Fig. 4. Upon the projecting arm 6, 7 of each standard 4, 5, and arranged
to traverse horizontally to and fro thereon, is mounted a transverse slide 10, 11
provided with a drilling headstock 12, 13, and with suitable mechanism whereby
reversible rotary motion can be imparted to the spindle 14, 15 of the drilling
headstock from a shaft arranged along the projecting arm of the standard.
will be obvious that the spindle can be provided with a screwing tool instead
of a drill or boring tool, when required. The drilling headstocks 12 and 13
are arranged to swivel on and be secured to their respective transverse slides 10
and 11 at various angles in the transverse vertical plane of the slide, the head-
stocks being provided with worm segments 12", 18" engaged by worms 12, 13h
operated by hand. Along the front of the machine extends a base plate 16 to
which the work may be secured when required.
It
Each of the rotatable nuts 9 carried by the sliding carriages 2, 3 and engaging
with the non-rotatable screw 8 is provided with a double clutch piece 17 adapted
to be engaged with a part clutch upon a worm wheel 19, or with a part clutch
upon a bevel wheel 21, according as it is desired to traverse the sliding carriage
by hand or power.

page_text: When the double clutch piece 17 of either carriage is engaged with the part
clutch on the corresponding worm wheel 19, the said carriage may be traversed
by hand by means of a worm shaft 20, that gears with the worm wheel 19 and
extends to the rear of the machine, where it can be fitted with a suitable handle.
Rods or spindles 18 are provided for moving the double clutch pieces into, or
out of, engagement with their corresponding part clutches. To traverse a
sliding carriage quickly by power, its double clutch piece 17 is engaged with
the part clutch on the corresponding bevel wheel 21, which gears with another
bevel wheel 21 fixed upon a shaft 22, having at its upper end a spur wheel 24,
in gear with another spur wheel 25; the spur-wheel 25 gears with a spur wheel 26
secured to the upper end of a vertical shaft 27, having at its lower end a bevel
wheel 28. 29, are a pair of reversing bevel wheels on the driving shaft,
either of which can be meshed with the wheel 28. The traversing mechanism
of each sliding carriage is similar but that of the carriage 2 is driven from the
driving shaft 30 whilst that of the carriage 3 is driven from the shaft 31.
The transverse slide 10, is traversed horizontally to and fro along the arm G,
by means of a rotating screw 32 working in a nut on the slide. The rotating
screw 32 carries at one end a part clutch 32, the other part of which is fixed
to a spur wheel 33, in gear with a spur wheel 34 on a shaft 35. 36 is a bevel
wheel, also on the shaft 35, meshing with a bevel wheel 37 on a vertical shaft 38
which carries the spur wheel 25 hereinbefore referred to--which is driven
from the shaft 30 as before described. The transverse slide 11 is traversed by
like mechanism driven from the shaft 31. The shafts 30, 31 are driven from
headstocks 39, 40, as well understood.
The spindle 14 of the drilling headstock 12 is driven by the shaft 35 through
bevel wheels 41, 42, shaft 43, bevel wheels 44, 45 and sleeve 46, similar
mechanism being used to operate the spindle 15 of the drilling headstock 13.
Each of the spindles 14, 15, is provided with suitable arrangements of mechanism
for imparting, either by hand or power, vertical traverse.
The standards 4. 5 are swivelled on the longitudinal sliding carriages 2, 3
by hand gear comprising a worm 57-and a worm wheel 58 on the base of the
standards.
In place of one or more belt-driven headstocks, electric motors may be em-
ployed when two are required they may advantageously be arranged at opposite
ends of the bed. In some cases one shaft may drive two spindles, and, if desired,
eacli sliding carriage, with its standard and drilling headstock, may be driven
by its own electric motor, means being provided for suitably varying the speed.
In this case, the motor may be carried by the sliding carriage and standard,
the longitudinal driving shaft or shafts in the bed being then dispensed with.
Also, if desired, each sliding carriage 2, 3, may be moved along the bed by a
separate non-rotatable screw 8.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
Machinery or apparatus suitable for drilling, boring and internally screwing
or tapping holes in metal plates constructed arranged and operating substantially
as herein before described with reference to the accompanying drawings.
