PROVISIONAL SPECIFICATION.
Improvements in or Additions to Metallic Tubular Telegraph Poles
and Metallic Tubular Poles for other purposes.
We BULLERS LIMITED, of Sherlock Street Birmingham, in the County of
Warwick, Telegraph Engineers and Manufacturers and EDWARD JOHN
CHAMBERS, of Lingwood," St. James Road, Dudley in the County of Worcester,
Civil and Mechanical Engineer aud Director of Bullers Limited, aforesaid, do
hereby declare the nature of this invention to be as follows:-
The said invention consists of the additions to or use with metallic tubular
telegraph poles and metallic tubular poles for other purposes of the interchangeable
base attachments hereinafter described, whereby the metallic pole may be made at
will either into a driving pole for rapid erection or into a pole with a buckled
base plate which is sunk in the ground and earth rammed around it as is well
understood.
The interchangeable base attachment for making the pole into a driving pole
consists of a pointed hollow block of wrought iron or steel the said pointed block
having preferably the figure of an inverted cone and being provided at top with a
hollow screwed stem; and the interchangeable base attachment for making the
pole into a base plate pole consists of a square flange which is bolted to the buckle
base plate the middle of the upper side of the said flange being provided with a
hollow screwed stem.
That
The base end of the tubular telegraph or other pole of wrought or cast iron is
furnished with an internal or concave screw thread of a size proper for the screwed
stem of either of the base attachments hereinbefore described, to take into.
is to say, in order to make the pole into a driving pole the screw stem of the
pointed block is screwed into the bottom of the pole and in order to make the pole
into a base plate pole the screwed stem of the flange fixed to the buckled base plate
is screwed into the bottom of the pole.
Although we prefer to attach the interchangeable driving base attachment or
the buckled plate base attachment to the bottom end of the pole by screwing as
described yet other ways of connecting the interchangeable base attachments to the
pole may be adopted. For example, the stems may be plain or unscrewed and
passed by a sliding motion into the plain or unscrewed end of the pole; or the
plain stems of the interchangeable base attachments may be secured in the bottom
of the pole by a cross pin or cotter or cross pins or cotters passed through holes in
the stem of the said attachment and pole.

We BULLERS LIMITED, of Sherlock Street Birmingham in the County of
Warwick Telegraph Engineers and Manufacturers, and EDWARD JOHN
CHAMBERS, of "Lingwood," St. James Road, Dudley, in the County of Worcester
Civil and Mechanical Engineer, and Director of Bullers Limited, aforesaid, do
hereby declare the nature of the said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement :-
The said invention consists of the additions to or use with metallic tubular
telegraph poles and metallic tubular poles for other purposes of the interchangeable
base attachments hereinafter described, whereby the metallic pole may be made at
will either into a driving pole for rapid erection, or into a pole with a buckled base
plate which is sunk in the ground and earth rammed around it as is well
understood.
The interchangeable base attachment for making the pole into a driving pole
consists of a pointed block of iron or steel the said pointed block having preferably
the figure of an inverted cone and being provided at top with a screwed stem; and
the interchangeable base attachment for making the pole into a base plate pole
consists of a square flange which is bolted to the buckled base plate the middle of
the upper side of the said flange being provided with a screwed stem.
The base end of the tubular telegraph or other pole of wrought or cast iron is
furnished with an internal or concave screw thread of a size proper for the screwed
stem of either of the base attachments herein before described to take into. That
is to say, in order to make the pole into a driving pole the screwed stem of the
pointed block is screwed into the bottom of the pole and in order to make the pole
into a base plate pole the screwed stem of the flange fixed to the buckled base
plate is screwed into the bottom of the pole.
Although we prefer to attach the interchangeable driving base attachment or
the buckled base plate attachment to the bottom end of the pole by screwing as
described yet other ways of connecting the interchangeable base attachments to the
pole may be adopted. For example, the stems may be plain or unscrewed and
passed by a sliding motion into the plain or unscrewed end of the pole; or the
plain stems of the interchangeable base attachments may be secured in the bottom
of the pole by a cross pin or cotter or cross pins or cotters passed through holes in
the stem of the said attachment and pole.
Figure 1 represents in elevation and Figure 2 in plan an interchangeable driving
base attachment for a tubular metallic telegraph or other pole made according to
this invention, the said base attachment having a plain stem, and Figure 3 represents
the same applied to the bottom of a metallic tubular telegraph or other pole,
represented in section. a is the pointed block of the base attachment made of iron
or steel and is the plain stem of the same passed by a sliding motion into the
plain end of the pole c as represented in Figure 3.
Figure 4 represents the driving base attachment having an externally screwed
stem 62 for connecting it to the bottom of the telegraph or other pole c. In this
case the bottom of the pole c is screwed internally for receiving the externally
screwed stem b².
Figure 5 represents the driving base attachment having a plain stem with a
cross hole in it which attachment is connected to the bottom of the pole c by the
cross pin d (or cross pins) passed through the holes in the stem b and pole c and
screwed or bolted to the pole.

page_text: Figure 6 represents in side elevation and Figure 7 in plan an interchangeable
buckled plate base attachment made according to this invention, having a plain stem
and Figure 8 represents the same secured to the buckled plate and applied to the
hollow telegraph or other pole c. This base attachment consists of the square
flange e which is bolted to the buckled plate as represented in Figure 8, the
plain stem g of the said square flange e being passed by a sliding motion into the
bottom of the telegraph or other pole c. The buckled base plate f is sunk in
the ground and earth rammed around it in the ordinary way.
Figure 9 represents the buckled plate base attachment provided with an
externally screwed stem g2 which is screwed into the internal screw in the bottom
of the pole c and Figure 10 represents the buckled plate base attachment e, g
secured in the bottom of the pole c by a cross pin h (or cross pins) passed through
holes in the stem and pole and screwed or bolted to the pole.
In order to make a telegraph or other pole into a driving pole by the use of this
invention it is only necessary to apply either of the forms of driving base
attachments represented in Figures 3, 4 and 5 to the bottom of the pole, when the
pole may be driven into the ground in the ordinary way; and in order to make the
pole into a base plate pole the driving base attachment is removed from it and
replaced by a base plate attachment having the same kind of stem as that removed,
as represented in Figures 8, 9 and 10, and the square flange e of the base
attachment is bolted to the buckled plate and the latter secured in the ground as
before explained.
Having now particularly described and ascertained the nature of the said inven
tion and in what manner the same is to be performed we declare that we claim
as the said invention ;-
The addition to or combination with metallic tubular telegraph poles and metallic
tubular poles for other purposes of interchangeable base attachments of the kinds
and applied substantially as hereinbefore described and illustrated in the accom-
panying drawing, whereby the metallic pole can be made at pleasure either into a
driving pole or into a base plate pole.
