Year: 1882

page_text: LETTERS PATENT to Charles Curtoys of No G Lombard Street in the City of
London Secretary to The Consolidated Telephone Construction and Maintenance
Company Limited for an invention of "IMPROVEMENTS IN INSULATED SUPPORTS
FOR THE COMMUNICATING WIRES OF TELEPHONES"
PROVISIONAL SPECIFICATION left by the said Charles Curtoys at the
Office of the Commissioners of Patents on the 18th April 1882.
CHARLES CURTOYS of No 6 Lombard Street in the City of London Secretary to
The Consolidated Telephone Construction and Maintenance Company Limited.
"IMPROVEMENTS IN INSULATED SUPPORTS FOR THE COMMUNICATING WIRES OF
TELEPHONES."
My Invention relates to improvements in the insulated supports which are used
for carrying the wires of telephones and has for its object to provide a support
which can be readily and conveniently fixed in its carrier and to which the wires
may be more conveniently and readily connected than hitherto the said supports
being also lighter and cheaper in first cost than are such supports as at present
constructed.
According to my said Invention the support consists of two parts namely the
bracket and the insulator proper. The bracket consists of a curved iron arm the
one end of the said arm being screwed or fitted for ready attachment to the pole,
beain or other carrier. The other end of the said arm is roughened or notched-
The insulator proper is of an inverted cup form with a knob at top having a groove
in its upper part for the reception of the line wire and an annular groove beneath
for the reception of the fastenings or lashings of the said wire. This insulator
proper has a hole in its interior which hole has a roughenod surface and in this
hole a cement is placed and the insulator is then passed onto the roughened end of
the bracket the said end entering the hole in the insulator the cement when
hardened owing to the roughening of the parts securing the bracket and insulator
firmly together.
In fixing the insulator in position the screwed end of the bracket is driven or
fitted into the pole beam or carrier and the line wire is passed into the groove
below the said ball termination.

CHARLES CURTOYS of No 6 Lombard Street in the City of London Secretary to

"IMPROVEMENTS IN INSULATED SUPPORTS FOR THE COMMUNICATING WIRES OF
TELEPHONES,
My Invention relates to improvements in the insulated supports which are used
for carrying the wires of telephones and has for its object to provide a support
which can be readily and conveniently fixed in or to its enrrier and to which the
wires may be more conveniently and readily connected than hitherto the said
supports being also lighter and cheaper in first cost than are such supports as at
present constructed. Figure 1 of the accompanying drawing represent in elevation
and Figure 2 in vertical section (with the bracket and insulator-proper separated)
a support constructed according to my Invention. The said support consists of
two parts namely, the bracket A and the insulator proper B-The bracket A
consists of a curved iron arin a the one end of the said arm being provided with a
scrow as for ready attachment to the pole, beam, wall, chimney-stack or other
carrier. The other end of the said arm at aª is roughened or notched. The insulator
proper B is of an inverted cup form at b with a knob b at top having a groove b³
in its upper part for the reception of the line wire c (as shown in Figure 1) and
an annular groove b beneath for the reception of the fastenings or lashings d of
the said wire. This insulator proper B has a hole in its interior which hole has
a roughened surface and in this hole cement is placed and the insulator is then
passed onto the roughened end a³ of the bracket A the said end entering the hole f
the cement when hardened owing to the roughening of the parts securing the
bracket A and insulator B firmly together.
In fixing the insulator in position the screwed end at of the bracket A is driven
into the pole beam or other carrier or support and the line wire c is passed into the
groove in the top of the knob of the insulator proper B the said line wire
being secured therein by the lashings or fastenings & which are passed into the
groove below the said knob b
1 do not confine myself to the use of a scrow for fixing the bracket to the carrier
or support Figure 3 shows a modification wherein the bracket A is provided with
a plate & having holes therein through which screws or nails are passed to secure
the bracket in position.
Having now described and particularly ascertained the nature of the said
Invention and the manner in which the same is or may be used or carried into
effect would observe in conclusion that what I consider to bo novel and original
and therefore claim as the Invention secured to me by the liereinbefore in part
recited Letters Patent is.
The insulated support for the communicating or line wires of telephones as
herein before described and illustrated in the accompanying Drawings
In witness whereof I the said Charles Curtoys have to this my Specification
set my hand and seal this 28th day of September One thousand eight
hundred and eighty two.
