IMPROVEMENTS IN THE ANCHORING OF TELEGRAPH POLES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We ROBERT HARKNESS TWIGG of 30 Great George Street Westminster in the
County of Middlesex Civil Engineer and JOHN CLARKE JOHNSON of 19 Bridge
Street Wednesbury in the County of Staffordshire, Works Manager do hereby
declare the nature of our invention for IMPROVEMENTS IN THE ANCHORING OF
TELEGRAPH POLES to be as follows:-
:―
Our Improvements have for their object the prevention of the overturning of
Telegraph Poles, and consist of a method of double anchoring. For this purpose
we attach to that portion of Telegraph Poles which is inserted in the ground two
anchors; one at or near the surface of the ground, the other at or near the lowest
extremity of the pole. We make these anchors preferably of the forms shown by
Figures 1, 2, 3, 4, 5, and 6; but these forms may be varied, for instance, the lower
anchors (in the case of wooden telegraph poles) may be made as shown at Figures 7
and 8.
The upper anchors in figures 1, 3, 5; and 7, may be secured fast to the poles
before they are put into the ground, or they may be left loose and driven into the
ground after the poles are in place, and then fixed by being screwed up tightly or
firmly wedged.
The drawing shows at Figures 1, 3, 5, and 7, sections of ground with telegraph
poles in place having upper and lower anchors attached. Figures 2, 4, and 6, are
plan views of three of the upper anchors; and Figure 8, is a side view of the lower
anchor of Figure 7.

Our Improvements have for their object the prevention of the overturning of
Telegraph Poles, and consist of a method of double anchoring. For this purpose
we attach to that portion of telegraph poles which is inserted in the ground, two
anchors; one, at or near the surface of the ground, the other, at or near the lowest
extremity of the Pole. We make these anchors preferably of the forms shown by
Figures 1, 2, 3, 4, 5, and 6; but these forms may be varied, for instance, the lower

The upper anchors in Figures 1, 3, 5, and 7, may be secured fast to the Poles
before they are put in the ground, or they may be left loose and driven into the

poles in place having upper and lower anchors attached. Figures 2, 4, and 6, are
plan views of the upper anchors of Figures 1, 3, and 5; and Figure 8, is a side
view of the lower anchor of Figure 7.
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
I claim is
The double anchoring of Telegraph Poles as and for the purposes herein
described.
