My invention has for its object to form a simple efficient and expeditions con-
nection of the stranded wires used as stays for telegraph poles railway signal posts
and other like purposes.
To explain my invention I proceed to show how it can be applied for fixing the
stays of telegraph poles.
Hitherto the most improved method of fixing the stranded wire used for staying
telegraph poles has been to pass one end of the strand through an eye forming
part of a swivel or its equivalent attached to a wall or rod a portion being so passed
through and the strand is then bent or doubled upon itself so as to form a loop
round the eye and the end untwisted the untwisted wires being laid alongside the
strand and one by one these wires are wrapped round the strand immediately
adjacent to the loop the second one being wrapped when the end of the first wire
is reached and so on until all the wires are wrapped round or in some cases a
certain number of the wires only are so wrapped round the other wires being cut off
and turned down so as to form a hook over the last wrapping. The other end of
the stranded stay wire is passed round the pole at the required height and held in
position by staples the strand beyond the staples being untwisted and wrapped
round the strand as already described or in some cases instead of passing the wire
round the pole a belt with an eye is fixed round the pole or an eye bolt is fixed to
it and the stay is then fixed to the eye as at first described.
The objections to this (the ordinary method) are:-
First-It takes considerable time to make the joint and it can only be well made
by practised men.
Second-The joint is liable to unwrap before the full breaking strain of the wire
is arrived at.
Third-Wrapping the wire round when Galvanized wire is used cracks off the

page_text: Fourth-Soft wire giving from fifteen to twenty per cent stretch has to be used
so that it may with ease be wrapped round the strand as described whereas soft
wire is not well suited for stays as it has less than half the breaking strain of hard
wire and further it stretches about six per cent before three fourths of its ultimate
breaking strain is arrived at. It cannot therefore be used even up to three
fourths of its breaking strain as with six per cent stretch the stay would have
become so slack as to be of little use and with galvanized wire five per cent stretch
damages the zinc coating.
My invention is designed to overcome these defects and is as follows:—
First To fix the stranded wire to the support I attach to the eye of the swivel
or its equivalent a cylindrical or nearly cylindrical block of iron or steel having a
tapering hole in its axis a loop or eye being formed on the said block for fixing to
the swivel or its equivalent at that end in which the larger diameter of the
tapering hole is situated. Through the smaller end of this tapering hole the end of
the stranded wire is passed and to fix it a conical shaped pin is inserted into the
centre of the stranded wire at the larger end of the hole in the cylinder or block.
As strain is applied the pin which increases the diameter of the strand wire is
drawn up with the wire into the smaller diameter of the hole in the cylinder the
action being to effectually lock the strand in the cylinder owing to the hole in the
cylinder being so designed that its diameter at the end most distant from
the swivel will not allow the strand when increased in diameter by the insertion of
the pin to pass. In order to prevent the displacement of the conical pin before the
strain is applied one of the wires forming the strand may be left of greater length
than the others and the end of the said longer wire may be turned down or folded
upon itself and made to enter an axial hole in the base of the conical pin thereby
preventing the said pin retiring from the strand.
Second-To fix the stranded wire to the pole I use a cylinder provided with a
hook or an eye of the form already described in those cases where a belt with an eye
is fixed round the pole or an eye bolt is fixed to it but when it is desired to pass the
wire round the pole I employ an oblong or cylindrical block having in it two
parallel or nearly parallel holes the one bole being cylindrical and of a diameter
large enough for the wire to pass the other hole being tapered as already described.
To fix the stranded wire in this case it is passed through the cylindrical hole then
round the pole and its end is finally inserted in the conical hole the larger end of
which is most distant from the pole. The strand is fixed in the conical hole by
ineans of a taper or conical pin as hereinbefore described.
Another method of fixing the strand to the pole is to have three parallel or
nearly parallel holes through the block all tapered the larger diameter of two of
the holes and the smaller of one being at one end of the block in this case a length
of the stranded wire is cut off sufficient to pass round the pole and to lock into two
of the holes as described and the third hole is then used for the stay itself which is
fixed as already described.
When a strand of not more than three or four wires is used the tapered pin may
be notched or grooved to hold the wires in position when locked in the cylinder as
described.
Connections made according to my invention are very secure and where
galvanized wire is used the zinc coating is not damaged. Their application does
not require skilled labour and occupies but little time and they permit of the use
of strands of steel and hard wire.

Improvements in Connecting the Stranded Wires Used as Stays
for Telegraph Poles, Railway Signal Posts, and other likę
Purposes.
I HOWARD COCHRANE JOBSON of N° 196 Wolverhampton Street, Dudley in
the County of Worcester, Manufacturer do hereby declare the nature of my
Invention for " IMPROVEMENTS IN CONNECTING THE STRANDED WIRES USED AS STAYS
FOR TELEGRAPH POLES RAILWAY SIGNAL POSTS AND OTHER LIKE PURPOSES and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:—
"
My invention has for its object to form a simple efficient and expeditious
connection of the stranded wires used as stays for telegraph poles, railway signal
posts and other like purposes.
To explain my invention I proceed to show how it can be applied for fixing the
stays of telegraph poles.
Hitherto the most improved method of fixing the stranded wire used for staying
telegraph poles has been to pass one end of the strand through an eye forming
part of a swivel or its equivalent attached to a wall or rod a portion being so
passed through and the strand is then bent or doubled upon itself so as to form a
loop round the eye and the end untwisted, the untwisted wire being laid alongside
the strand and one by one these wires are wrapped round the strand immediately
adjacent to the loop, the second one being wrapped when the end of the first wire
is reached and so on until all the wires are wrapped round; or in some cases a
certain number of the wires only are so wrapped round the other wires being cut
off and turned down so as to form a hook over the last wrapping. The other end
of the stranded stay wire is passed round the pole at the required height and held
in position by staples, the strand beyond the staples being untwisted and wrapped
round the strand as already described; or in some cases instead of passing the wire
round the pole a belt with an eye is fixed round the pole or an eye bolt is fixed
to it and the stay is then fixed to the eye as at first described.
The objections to this (the ordinary method) are:-
First It takes considerable time to make the joint and it can only be well
made by practised men.
Second-The joint is liable to unwrap before the full breaking strain of the wiro
is arrived at.
Third Wrapping the wire round when Galvanized wire is used cracks off the
zinc coating and damages the wire.
Fourth Soft wire giving from 15 to 20 per cent stretch has to be used so that
it may with ease be wrapped round the strand as described, whereas soft wire is
not well suited for stays as it has less than half the breaking strain of bard wire
and further it stretches about 6 per cent. before three fourths of its ultimate
breaking strain is arrived at. It cannot therefore be used even up to three fourths
of its breaking strain as with 6 per cent. stretch the stay would have become so

page_text: slack as to be of little use and with galvanized wire 5 per cent stretch damages
the zinc coating.
My invention is designed to overcome these defects and is as follows:-
1st To fix the stranded wire to the support I attach to the eye of the swivel, or
its equivalent, a cylindrical or nearly cylindrical block of iron or steel having a
tapering hole in its axis, a loop or eye being formed on the said block for fixing to
the swivel or its equivalent at that end in which the larger diameter of the
tapering hole is situated. Through the smaller end of this tapering hole the end
of the stranded wire is passed and to fix it a conical shaped pin is inserted into the
centre of the stranded wire at the larger end of the hole in the cylinder or block.
As strain is applied the pin which increases the diameter of the strand wire is
drawn up with the wire into the smaller diameter of the hole in the cylinder, the
action being to effectually lock the strand in the cylinder owing to the hole in the
cylinder being so designed that its diameter at the end most distant from
the swivel will not allow the strand when increased in diameter by the insertion
of the pin to pass.
In order to prevent the displacement of the conical pin before the strain is
applied, one of the wires forming the strand may be left of greater length than the
others and the end of the said longer wire may be turned down or folded upon itself
and made to enter an axial hole in the base of the conical pin, thereby preventing
the said pin retiring from the strand.
2nd To fix the stranded wire to the pole I use a cylinder provided with a hook
or an eye of the form already described in those cases where a belt with an eye is
fixed round the pole or an eye bolt is fixed to it, but when it is desired to pass the
wire round the pole I employ an oblong or cylindrical block having in it two
parallel or nearly parallel holes, the one hole being cylindrical and of a diameter
large enough for the wire to pass, the other hole being tapered as already described.
To fix the stranded wire in this case it is passed through the cylindrical hole, then
round the pole and its end is finally inserted in the smaller end of the conical hole,
the larger end of which is most distant from the pole. The strand is fixed in the
conical hole by means of a taper or conical pin as hereinbefore described.
Another method of fixing the strand to the pole is to have three parallel or
nearly parallel holes through the block all tapered, the larger diameter of two of
the holes and the smaller of one being at one end of the block; in this case a
length of the stranded wire is cut off sufficient to pass round the pole and to lock
into two of the holes as described and the third hole is then used for the stay itself
which is fixed as already described.
When a strand of not more than three or four wires is used the tapered pin may
be notched or grooved to hold the wires in position when locked in the cylinder as
described.
Connections made according to my invention are very secure and where
galvanized wire is used the zinc coating is not damaged. Their application does
not require skilled labour and occupies but little time and they permit of the use
of strands of steel and hard wire.
.
I will now proceed to describe with reference to the accompanying Drawing the
manner in which my invention is to be performed.
Figures 1 and 2 represent elevations taken at right angles to one another of a
stranded wire connection, for staying telegraph poles and for other like purposes,
constructed according to one of my arrangements or methods. The same letters of
reference indicate the same parts in the several Figures of the drawing: A is the
stranded wire and B is the eye of the swivel which is connected to a wall or to
the stay rod at the ground: C is the cylindrical or nearly cylindrical block which
I employ to form the connection the said block having at one end the loop E to
which the eye B of the swivel stay rod is fixed as represented. In the axis of the
block C is a tapering hole F H indicated in dotted lines for receiving the stranded
Stay wire A and the fixing or locking tapering pin or plug G. In order to form

page_text: the connection the stranded wire A is passed through the smaller end of the tapering
hole F H in the block C into the loop E and is fixed by driving the conical shaped
pin or plug G into the middle of the stranded wire A at the wide end of the conical
hole F. H so as to expand the wire, the said conical pin or plug G entering the
conical hole in the block as indicated in the drawing. On the strain being
applied to the stranded wire A the pin or plug G enclosed in the expanded end of
the stranded wire A, is drawn into the conical hole F H and the said stranded wire
is thereby locked in the said hole in the block in consequence of the smaller end of
the said hole not permitting the expanded end of the strand to pass through it as
will be understood by an examination of the drawing.
The displacement of the conical pin G before the strain is put upon the strand
may be prevented by leaving one of the wires forming the strand of greater length
than the others and folding or doubling the said long end of the strand and
making its end enter an axial bole in the conical pin G as represented at J
Figure 1. By this means the taper or conical pin or plug G is prevented retiring
from the strand. Figures 3 and 4 represent elevations taken at right angles to
one another of the method of attachment last described but instead of combining
with the cylindrical or nearly cylindrical block C a closed loop as represented in
Figures 1 and 2, an open or hook shaped loop E2 is employed for attaching the eye
of the swivel of the stay rod to it. Or the cylindrical or nearly cylindrical
block C may be furnished with two parallel extension lugs and a cross pin for
the same purpose as represented in the elevations taken at right angles to one
another in Figures 5 and 6, where the extension lugs are marked L, L and the
cross pin K.
I will now describe my methods or arrangements for fixing the stay stranded
wire to the pole.
When a belt with an eye is fixed round the pole, or an eye bolt is fixed to the
pole, I use either of the arrangements or connections represented in Figures 1. 2.
3. 4. 5 and 6.
When the stay stranded wire is to be passed round the pole I use either of the
arrangements represented in Figures 7, 8, 9 and 10.
One of the arrangements is represented in Figure 7 and part of the same in
Figure 8. In this arrangement I employ the block M having in it two holes N
and P, Qslightly inclined to one another. The hole N is cylindrical and of a
diameter sufficiently large for the stranded wire A to pass through it; the other
hole P, Qis taper as described with respect to the hole in the block C Figures 1.
2. 3. 4. 5 and 6.
In order to fix the stranded wire to the pole the stranded wire A from the
ground is first passed through the cylindrical hole N in the block M (see Figure 7)
then round the pole R and the end A² of the stranded wire is then passed through
the taper hole P, Q and fixed in the said hole by driving the taper pin or plug G
into the middle of the said stranded wire and expanding the strand wire as before
described.
Another of my arrangements for fixing the stranded wire to the pole is
represented in Figure 9 and part of the same in Figure 10. In this arrangement,
the block M is furnished with three tapering holes marked respectively S, T and V.
The smaller ends of the tapering holes S, T are both situated at the same end of
the block M while the smaller end of the tapering hole V is situated at the
opposite end of the block M. In this arrangement the block M is connected to
the pole R by an independent piece of stranded wire A³, the stranded wire for the
stay itself being attached to the middle hole V in the block.
In effecting the attachment, a length or piece of the stranded wire is cut off
sufficient to encircle the pole R and pass through the tapering holes S and T, in
which holes its ends are locked by the taper or conical pins or plugs G, G as before
described. In the middle tapering hole V the end of the stranded wire A for the
stay is passed and fixed in a similar manner by the plug G.

page_text: Figure 11 represents a telegraph pole provided with a stranded wire stay
connected to the eye of the swivel of the stay rod at the ground and to the pole
according to my invention.
In the said Figure 11 the connection at X of the stranded wire A to the ground
is constructed according to one of the arrangements hereinbefore described and
illustrated in Figures 1. 2. 3. 4. 5 and 6 and the connection at Y to the telegraph
pole is constructed according to one of the arrangements hereinbefore described and
illustrated in Figures 7. 8. 9 and 10 of the drawing.
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 I claim
as my invention of "Improvements in connecting the stranded wires used as stays
for telegraph poles railway signal posts and other like purposes"
First. Connecting the stranded stay wire to the support at a wall or at the
ground by the construction and combination of parts hereinbefore described and
illustrated in Figures 1. 2. 3. 4. 5 and 6 of the accompanying Drawing; that is to
say, the combination with a loop or its equivalent to be attached to the swivel
stay rod or other like support at the wall or ground, of a metallic block preferably
cylindrical or conical having in it a tapering axial hole into which hole the end of
the stranded stay wire is expanded and locked substantially as described and
illustrated.
Secondly. The application of the arrangements specified in the preceding
claim to connecting the stranded stay wire to the pole or post where a belt with
an eye is fixed round the pole or post or an eye bolt is fixed to the pole or post as
hereinbefore described.
Thirdly. Connecting the stranded stay wire to the telegraph pole or other pole
or post by the construction and combination of parts hereinbefore described and
illustrated in Figures 7, 8, 9 and 10 of the accompanying Drawing; that is to
say, fixing the stranded stay wire by the use of a metallic block having two holes
in it, one cylindrical and the other taper, and locking the end of the stranded
stay wire in the taper hole as described and illustrated in Figures 7 and 8; or a
metallic block having in it three taper holes arranged as described and illustrated,
the ends of the stranded wire passing round the pole or post being locked in the
outer taper holes and the end of the stranded stay wire being locked in the middle
taper hole substantially as herein before described and illustrated in Figures 9
and 10.
