Light Cables, Telegraph Wires, Telephone Wires, and other
Cables, Wires, and Rods, to Insulators.
I EDWARD JOHN CHAMBERS of Lingwood Saint James' Road Dudley in the County
of Worcester Civil and Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention consists of the construction and combination of the parts hereinafter
described of appliances for attaching or fastening telpher cables, and electric
light cables, telegraph wires, telephone wires, and other cables, wires, and rods, to
insulators.
I will describe my invention as applied to the attaching or fastening of telpher
cables to insulators.
I form the upper part of the insulator, of a shape proper to receive a clip or clamp
of the kinds hereinafter described, the top of the insulator, which is concave or
troughlike, receiving the cable which is held and gripped firmly between the said top
of the insulator and the curved top of the clip or clamp.
One construction of clip or clamp which I use consists of a strip of sheet metal
doubled and bent, at its middle. into an inverted V-shape. The middle of the lower
part of each branch of the clip is forked or slotted, and the lower forked edge of each
branch is bent or coiled upwards so as to form hooks. The forked sides of the clip
are to enable the clip to pass over the projecting ends of the cross bar hereinafter
described inserted in the insulator and the hooks are used in conjunction with the said
cross bar for receiving the fixing wedges for securing the clip to the insulator. Near
the top of the insulator a transverse hole is made in which a bar (or its equivalent) is
inserted. This bar is preferably semi-circular in cross-section and is of such a length
that when inserted in the insulator, its ends project from the sides of the insulator.
In the projecting ends of the cross bar and in the flat face thereof, notches are made.
These notches in conjunction with the hooked ends of the branches of the clip form
seats for the fixing wedges.
In attaching or fastening the telpher cable to the insulator the cable is laid in the
concave or trough top of the insulator and the clip is passed with its wide end
downwards on to the insulator and cable, the slotted or forked sides of the clip passing
over the projecting ends of the cross bar in the insulator. Wedges are now inserted
between the hooked ends of the clip and the notches in the cross har so as to securely
bind the clip to the insulator and hold the cable securely in its place between the top
of the insulator and top of the clip.
Instead of forking or slotting the bottoms of the branches of the clip, elongated
closed slots may be used for the ends of the cross bar to pass through. In this case
the extreme ends of the branches are bent upwards to form flanges for supporting the
fixing wedges.
In securing wires to the insulator a loose cap of porcelain or other insulating
material may be used aft the top of the insulator, the wire being gripped when the clip
is in its place between the top of the insulator and the said cap. The wire is thus
insulated at the point of grip, the gripping faces of the insulator and cap being
preferably corrugated or notched to prevent the slipping of the wire.
In another form of clip or clamp which I use the clip is without forked or slotted
ides and the ends of the branches of the clip are flanged and perforated or screwed
r receiving the clip fixing screw bolts or eye bolts or screws as hereinafter
ribed.
›n I use the last described clip the cross bar in the insulator is a plain bar or its

page_text: projecting ends have either plain or screwed holes in them. The length of this clip is
such that when placed on the insulator, its flanges are situated above tue cross bar in
the insulator. When eye bolts are used to fix the clip the eye ends of the bolts are
engaged with the ends of the cross bar and the screwed ends of the bolts, which have
been passed through the flanges of the clip, are fixed by screw nuts.
When screws are used they are passed through the Hanges of the clip and screwed
into the tapped holes in the ends of the cross bar and when screw bolts are used the
screw bolts are are passed through the ends of the cross bar and flanges of the clip
and fixed by screw nuts.

Improvements in Attaching or Fastening Telpher Cables and Electric
Light Cables, Telegraph Wires, Telephone Wires, and other
Cables, Wires, and Rods, to Insulators.
I EDWARD JOHN CHAMBERS of Lingwood Saint James' Road Dudley in the County
of Worcester, Civil and Mechanical Engineer do hereby declare the nature of my
invention and the manner in which the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention consists of the construction and combination of the parts hereinafter
described of appliances for attaching or fastening telpher cables and electric light
cables, telegraph wires, telephone wires and other cables, wires and rods to
insulators.
I will describe my invention as applied to the attaching or fastening of telpher
cables to insulators.
I form the upper part of the insulator of a shape proper to receive a clip or clamp
of the kinds hereinafter described the top of the insulator which is preferably concave
or trough like receiving the cable which is held and gripped firmly between the said
top of the insulator and the curved top of the clip or clamp. One construction of clip
or clamp which I use consists of a strip of sheet metal doubled and bent at its middle
into an inverted V shape. The middle of the lower part of each branch of the clip
may be forked or slotted and the lower edge of each branch is bent or coiled upwards
so as to form hooks. When the sides of the clip are forked the clip can pass over the
projecting ends of the cross bar hereinafter described inserted in the insulator and the
hooks are used in conjunction with the said cross bar for receiving the fixing wedges
for securing the clip to the insulator. Near the top of the insulator a transverse hole
is made in which a bar (or its equivalent) is inserted. This bar is preferably semi-
circular in cross section and is of such a length that when inserted in the insulator its
ends project from the sides of the insulator. In the projecting ends of the cross bar
and in the flat face thereof, notches are made. These notches in conjunction with the
hooked ends of the branches of the clip form seats for the fixing wedges.
In attaching or fastening the telpher cable to the insulator the cable is laid in the
concave or trough top of the insulator and the clip is passed with its wide end
downwards onto the insulator and cable the slotted or forked sides of the clip passing
over the projecting ends of the cross bar in the insulator. Or the bar may be inserted
in the insulator after the clip is in position. Wedges are now inserted between the
hooked ends of the clip and the notches in the cross bar so as to securely bind the clip
to the insulator and hold the cable securely in its place between the top of the
insulator and the top of the clip.
Instead of forking or slotting the bottoms of the branches of the clip, elongated
closed slots may be made for the ends of the cross bar to pass through. In this case
the extreme ends of the branches may be bent upwards to form flanges for supportir
the fixing wedges.

page_text: In securing wires to the insulator a loose cap of porcelain or other insulating
material may be used at the top of the insulator the wire being gripped when the cap
is in its place between the top of the insulator and the said cap. The wire is thus
insulated at the point of grip the gripping faces being preferably corrugated or
notched to prevent the slipping of the wire.
In another form of clip or clamp which I use the clip is without forked or slotted
sides and the ends of the branches of the clip are flanged and perforated or screwed
for receiving the clip fixing screwed bolts or eye bolts or screws as hereinafter
described. When I use the last described clip the cross bar in the insulator is a plain
bar or its projecting ends have either plain or screwed holes in them. The length of
this clip is such that when placed on the insulator its flanges are situated above the
cross bar in the insulator. When eye bolts are used to fix the clip the eye ends of
the bolts are engaged with the ends of the cross bar and the screwed ends of the
bolts which have been passed through the flanges of the clip are fixed by screw nuts.
When screws are used they are passed through the flanges of the clip and screwed
into the tapped holes in the ends of the cross bar and when screw bolts are used the
screw bolts are passed through the ends of the cross bar and flanges of the clip and
fixed by screw nuts.
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 and
Figure 3 represents in plan appliances constructed according to my invention for
attaching or fastening a single telpher cable to insulators, the central stems of the
insulators being supported by brackets or other supports in the ordinary way. The
travelling carriage carrying the case or load works on the single telpher cable in
the ordinary way; Figure 4 represents a separate view of a fixing clip having
forked ends.
Figure 5 represents two telpher cables arranged side by side for supporting the
travelling carriage like the pair of rails of a railway, the telpher cables being attached
or fastened to the insulators according to my invention; Figure 6 represents a portion
of Figure 5 drawn to a larger scale and Figure 7 represents a modification of
Figure 6 Figures 8. 9. 10 and 11 represent other modifications and details of my
invention as hereinafter described.
I will first describe the arrangement represented in Figures 1. 2 and 3.
a is the insulator supported on the stem b secured to a bracket or other support.
The said insulator is made concave or trough shaped at top marked e for receiving the
telpher cable d. The said insulator is also furnished with a transverse hole or passage
for receiving the clip fixing cross bar f; g is the sheet metal clip, cap or clamp
between the curved top of which and the top of the insulator a the cable d'is held and
gripped as best seen in Figure 2. By an examination of Figure 2 it will be seen
that the said clip, cap or clamp g has nearly the figure of the letter V inverted.
Rivetted to the clip gare side plates and cross pieces, the turned ends of the
latter embracing the insulator in the manner seen in Figures 2 and 3. The bottom
of each branch of the clip g is bent or coiled upwards so as to form hooks or seats i, i
and in each of the said branches an elongated slot e is made through which the ends
of the cross barf in the insulator pass. The flat faces of the projecting ends of the
cross har fare notched for receiving the fixing wedges k, k.
In attaching or fastening the telpher cable d to the insulator a the said cable is laid
in the concave or trough top c of the insulator and the clip or cap g is passed onto the
insulator and cable as represented in the Drawing. After the clip has been put in
position the cross bar is passed through the insulater and holes e in the branches of
the clip and the wedges k, k are inserted and driven between the turned up or hooked
ends i, i of the clip and the notches in the projecting ends of the cross bar f. The
clip is thus bound firmly to the insulator and the cable at the same time held securely
in its place between the top of the insulator and the top of the clip as seen in the
Drawing.

page_text: Figure 4 represents an elevation of the clip g in which the lower end of each
branch is forked or slotted at for passing over the projecting end of the cross bar f
in the insulator. In this modification the cross bar may be inserted in the insulator
before or after the clip or cap g is put in its place on the insulator.
I will now describe the two felpher cables represented in Figures 5. 6 and 7
attached to the insulators according to another of the arrangements of my invention.
In the said Figures 5. 6 and 7, m, m are the insulators fixed to the sleeper in
the ordinary way and p p are the telpher cables fixed between the top of the
insulators and clips in the manner hereinbefore described; is the travelling
carriage working on the telepher cables In the arrangement Figures 5 and 6 the
clip g is secured to the cross bar f in the insulator m by means of flanges g², 92 on
the bottoms of the branches of the clip and screw bolts and nuts", ". The screw bolts
are passed through plain holes in the flanges g² of the clip and cross har and the
screw nuts screwed on the ends of the screw bolts on the underside of the cross bar as
illustrated in the Drawing. Or in place of screw bolts and nuts, screws may be used
as illustrated in Figure 7. In this case the projecting ends of the cross bar fare
screw tapped and the screws s are driven into the tapped holes in the ends of the
cross bar as represented.
Figure 8 represents an arrangement in which eye bolts are used for connecting the
clip to the cross bar in the insulator. The eye bolts are marked t, t and are engaged
with the ends of the cross bar and fixed by screw nuts as represented. When a
cross har semicircular in cross section is used, eye bolts of the shape represented
at u Figure 9 are used and when a cylindrical bar is used, eye bolts of the kind
represented at Figure 9 are used.

In place of wedges, screw bolts and nuts screws and eye bolts for fixing the clip to
the cross bar each branch of the clip may carry an eccentric holder or fastener as
represented in side elevation in Figure 10, where the eccentric holder or fastener is
marked a.
It works on the projecting end of the cross bar and is turned by a
spanner fitting on the said bar and on the pin ². By turning the eccentric holder a
by acting on the projecting pin a² the said holder can be tightened on the cross bar f
and the clip y fixed to the said cross bar.
Figure 11 represents the arrangement of my invention in which a loose cap y of
porcelain or other insulating material is used at the top of the insulator m, the wire p
being gripped when the clip g is in its place between the top of the insulator and the
said cap y.
The gripping faces of the insulator and cap are corrugated (preferably) as repre-
sented to prevent the slipping of the wire. The fixing cap y is also shown in Figure 8.
The clip represented in Figure 11 is fixed to the insulator by the wedge arrangement
herein before described and illustrated in Figures 1, 2 and 3.
Although I have represented the best means with which I am acquainted of fixing
the gripping clip, cap or clamp to the insulator so as to grip the cable and insulate it
at the same time yet I wish it to be understood that other equivalent arrangements
may be adopted for fixing the clip to the insulator.
I apply my invention to the attaching or fastening of electric light cables, telegraph
wires, telephone wires and other cables, wires and rods to insulators substantially in
the manner herein before described and illustrated with respect to telpher cables
and wire.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that 1
claim as my invention :-
:-
The improvements hereinbefore described and illustrated in the accompanying
Drawing in attaching or fastening telpher cables and electric light cables telegraph
wires telephone wires and other cables wires and rods to insulators; that is to say the
use for the purpose described of a metal clip, cap or clamp constructed and applied to
the upper part of the insulator and fixed thereto substantially as described and

page_text: illustrated whereby the gripping of the cable, wire or rod between the curved top of
the clip cap or clamp and the top of the insulator at the same time insulates it. Also
the combination with the clip or clamp of a supplementary cap so as to insulate the
cable wire or rod at the point of grip substantially as described and illustrated.
