Improvements in Machinery for Drilling and Tapping and Inserting
Ferrule Taps and Plugs in Gas and Water Mains and Fixing
Saddle Backs on Mains.
.
JOHN RUSCOE Engineer, Albion Works Hyde, Cheshire do hereby declare the
nature of this invention to be as follows:-
It consists of a Cylinder or Stand to be fixed on the mains and held thereon by
means of chains passing round the main tightened up by screws on each side, between
the stand and main there is a separate saddle piece with leather or other packing to
form a water tight joint between the stand and the main, the Cylinder is bored out
from the top to a seating near the bottom of the Cylinder immediately between which
is a cavity or space prepared for and in which a disc Valve can slide to a dead joint
and thus effectively shutting off and when the main is drilled preventing any water or
gas rising above it and upwards in the Cylinder, the Valve is actuated by an external
handle having a defined position indicating when the Valve is opened or closed, this
chamber is made Water or Gas tight by means of a cover having faced joints and set
screws. Turned Chucks are made to slide in the bored Cylinder which Chucks have a
ring of packing to still further fill the Cylinder and prevent escape, the Chucks_are
made hollow at the lower end to hold the special drills and Taps, and Ferrule Taps
which being truly Chucked and concentric in action are positive in their operation.
The external part of Cylinder has a bracket or lug on either side to which is attached
a Strap, or Bridle, or Bow having a central boss with feeding screw passing through
and impinging at its point upon the Chuck upon tho square of which is fixed a
suitable Ratchet Brace, and has the Chuck is worked down the screw is brought down
also as a feed which motion can be reversed at pleasure.
The Ferrule Tap is made with a loose screw or cone or plug working by means of
a tee cross handle below the outlet branch when water is shut off, and being drawn
above the branch when water can be passed along the service pipe.
For large services or branch mains the Cylinder or Stand is converted into a fixed
saddle back secured to the main by set screws, bolts or straps at pleasure or both, the
saddle back is bored out to receive specially made Cup Drills, and the Disc Valve is
used here as well as in the foregoing the same detail and principles being followed.
Dated this 31st day of October 1888.

Improvements in Machinery for Drilling and Tapping and Inserting
Ferrule Taps and Plugs in Gas and Water Mains and Fixing
Saddle Backs on Mains.
JOHN RUSCOE Engineer, Albion Works Hyde, Cheshire 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 :-
It consists of a Cylinder or Stand to be fixed on the mains and held thereon by
means of chains passing round the main tightened up by screws on each side, between
the stand and main there is a separate saddle piece with leather or other packing to
form a water tight joint between the stand and the main, the Cylinder is bored out
from the top to a seating near the bottom of the Cylinder immediately between which
is a cavity or space prepared for and in which a disc Valve can slide to a dead joint
and thus effectively shutting off and when the main is drilled preventing any water
or gas rising above it and upwards in the Cylinder, the Valve is actuated by an

page_text: external handle having a defined position indicating when the Valvo is opened or
closed, this chamber is made water or gas tight by means of a cover having faced
joints and set screws. Turned Chucks are made to slide in the bored Cylinder which
Chucks have a ring of packing to still further fill the Cylinder and prevent escape,
the chucks are made hollow at the lower end to hold the special drills, and Taps, and
Ferrule Taps, which being truly chucked and concentric in action are positive in their
operation. The external part of Cylinder has a bracket or lug on each side to which
is attached a strap or bridle, or Bow, having a central boss with feeding Screw passing
through and impinging at its point upon the Chuck upon the square of which is fixed
a suitable Ratchet Brace, and has the Chuck is worked down the screw is brought
down also as a feed which motion can be reversed at pleasure.
The Ferrule Tap is made with a loose Screw, or Cone, or Plug working by means
of a tee cross handle below the outlet branch when the water is shut off, and being
drawn above the branch when water can be passed along the service pipes. For large
services or branch mains the Cylinder or stand is converted into a fixed saddle back
secured to the Main by set screws, bolts or straps at pleasure or both, the saddle back
is bored out to receive specially made Cup Drills, and the disc Valvo is used here as
well as in the foregoing the same detail and principles being followed.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying drawing reference being had to the figures
and letters marked thereon.
Fig. 1. is a sectional elevation of my main pipe drilling machine through line A B
Fig. 2.
A is a Cylinder bored out perfectly true, B is a turned chuck to fit A on which is a
packing cc held in position by a nut and washer dd, C is a Tap held in position by
the said chuck B, D is a disc Valve when closed, E is a saddle on which is a packing F,
Fig. 2 is a section through line B B, C C Fig. 1. shewing disc Valve open.
Fig. 4 is a sectional elevation of my improved Cup Drill, A is a block turned
perfectly true on which are attached by screws a number of steel tools or cutters in
grooves prepared for them as shown at B also a number of dirt or clearance grooves
as shown at C, and G is a packing fastened by nut and washer H H.
Fig. 5 is a sectional elevation of ferrule tap, D is a plug to raise or lower so as to
open or close by means of a square key to fit in recess as shown at E, F is a cover
or cap to be screwed home when the said tap is open.
Having stated the nature of my Invention and described the manner of performing
the same I would have it understood that I do not limit myself to the details given as
they may be varied or modified and I declare that I claim
1st. The Disc Valve in Drill stand and saddle back for the purposes of under
pressure connections being made.
2nd. The turned Chuck and packings for the use and purpose of making under
pressure connections as described.
3rd. The Cup Drilis made without external ring and to work through a bush for
the purpose of under pressure and other work as shown at I Fig 3.
4th. The Ferrule Taps in combination with the Chucks for under pressure
connections.
In witness whereof I the said John Ruscoe have hereunto set my hand this
Thirtieth day of July One thousand eight hundred and eighty-nine.
