PROVISIONAL SPECIFICATION.
Improvements in and connected with Securing Stays for Posts,
Poles, and the like.,
I, GEORGE GILLMORE of 10 Athol Street Douglas, Isle of Man, Electrical
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to securing stays for telegraph poles, fencing posts and
the like, and its object is to avoid the necessity for digging holes for the stay rods
as at present. This necessity involves a considerable amount of labour and loss
of time, particularly in clay and sandy soils and where many tree roots are present,
besides in the latter case, causing injury to the trees.
According to my invention construct the stay rods, or their lower portion,
with a spiral screw thread increasing gradually in diameter from the bottom point
of the rod upwards. Preferably the screw thread may be constructed after the
manner of a cork-screw, with or without a central vertical supporting rod, or it
may in some cases have the form of an exaggerated gimlet point. In the former
case, the spiral rod may have any suitable cross section.

Improvements in and connected with securing Staye for Posts,
Poles, and the like.
I, GEORGE GILLMORE, of 10 Athol Street, Douglas in the Isle of Man,.
Electrical 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 relates to securing stays for telegraph poles, fencing poles and
the like, and its object is to avoid the necessity for digging holes for the stay
rods as at present. This necessity involves a considerable amount of labour and
loss of time particularly in clay and sandy soils and where many tree roots are.
present, besides, in the latter case, causing injury to the trees.
A stay rod constructed according to my invention is provided at its lower part
with a screw thread the diameter of which increases from its point and the form
of which may be varied according to the ground in which it is to be used. Thus,.
for hard ground, the screw thread may be supported by or formed upon a central
shaft, whilst for ground containing roots the screw may be formed like a cork-
Borew.
The accompanying drawings, to which I refer hereinafter, illustrate different.
forms of my improved stay rods and a device by means of which they may be
screwed into the ground. In all the figures the stay rods are shown as consisting

page_text: of two parts, as this has been found the most convenient way of constructing them,
but it will, of course, be understood that they may each consist of a single piece.
Similar letters of reference are used to indicate similar parts where they occur
in the different figures.
Figure 1 illustrates a form of stay rod specially adapted for use in clay or hard
ground. The rod consists of two parts A and B the lower of which, B, is
provided with a screw thread C upon a central shaft D. Means are provided to
enable the two parts to be secured together, as for examplo by forming the part B
with a socket into which the upper part fits and is held by a transverse screw or
pin E. One of the parts is formed to engage with a key or the like by means of
which the part B may be screwed into the ground.
The stay rod illustrated in Figure 2 is designed for use in ground containing
tree roots and other obstacles. Its. lower screwed part is formed as a corkscrew
is, and is preferably circular in cross section. This form may also, if desired, be
provided with a central supporting rod or shaft, which may or may not support
the screw thread throughout the whole of its length.
Figure 3. illustrates in elevation a key which may be employed for screwing the
rods into the ground, and Figure 4 shows the same key in section in place upon
a rod. The key F is a box key adapted to fit over the upper part A of the
stay rod and is formed at its mouth to engage with a square or the like G upon
the part B. A ratchet and pawl is preferably introduced between the key and the
handle H so that the latter can move independently in one direction. The
operation of screwing can thus be expeditiously performed.
In the figures previously referred to the two parts of the stay rod are shown
connected together before being placed in the ground, but, as represented in
Figure 5, the lower part B may be screwed separately into place, and have the
'part A attached afterwards.
The stay rods are preferably formed from wrought iron and may be protected
from corrosion in any usual or known manner.
Having now particularly described and ascertained' the nature of my said inven-
tion and in what manner the same is to be performed, I declare that.what 1
claim is :-
A stay rod for telegraph poles or the like, having its lower part formed or
provided with a screw thread, substantially as and for the purpose hereinbefore
described and as illustrated by the acconipanying drawings.
