Improvements in Electric Conducting Cords, and Means for Connecting
them to Walls and other Supports.
We, MOR KÁROLY PERCI, and FRIGYES SCHACHERER both of Szigony-ut 21,
Budapest VIII, Hungary, do hereby declare the nature of this invention to be as
follows:-
The fixing of the conducting cords of electric-light leads in dwellings by the
direct attachment of the cords to the walls which has heretofore been usual, has
been found to be inadmissible from the point of view of safety.
It has, therefore, been prescribed that the leads shall be arranged and fixed freely
suspended at a distance away from the wall.
The means that have heretofore been proposed for carrying out this mode of
fixing are unsuitable either for aesthetic reasons or because the use of such means
unavoidably damages the paint or paper on the walls and the manner of fixing is
troublesome.
Now the present invention relates to a means for fixing the leads, which conforms
in every respect with the above mentioned regulation and also does not spoil the
appearance of the leads in elegant rooms. These means consist of distance-pieces,
which also serve as insulators, and the essence of the invention consists in weaving
these distance-pieces in the covering whilst the said covering is being woven around
the conducting wires, with the result that the said distance-pieces are firmly and
securely connected to the conducting cord and enable the latter to be quickly and
firmly fastened at the required distance from the wall.
These distance-pieces each consist of a sleeve or piece of tube made of one or two
parts and composed of insulating material such as bone, celluloid, hard rubber.
wood, etc. This sleeve or piece of tube is formed in the first case with a groove in
which the conducting wires are placed and in which they are held by the woven
covering; whilst the bipartite sleeve is composed of two sleeves one of which is
slipped over the other, which are of unequal length, and the longer one of which
has a projecting portion of its edge, between which and the shorter tube piece the
wire leads are placed and are woven around together with the distance-piece.
The accompanying drawing illustrates several examples of distance-pieces of
this kind.
Figs. 1 and 2 are respectively a side elevation and a front elevation of a con-
ducting cord fixed to a wall by means of a distance-piece of this kind; and
Fig. 3 is a section showing the integral distance-piece employed therein.
Figs. 4 and 5 are respectively an elevation and a plan of one example of integral
distance-piece and Figs. 6 and 7 are similar views of another example.
Figs. 8 and 9 are sections of the two parts (separated from each other) of a
bipartite distance-piece similar to that shown in Fig. 3; whilst Figs. 10 and 11
show two modified forms of bipartite distance-pieces.
As shown in Figs. 3 to 7, the integral distance-piece consists of a tubular piece
having an annular groove a which is limited at one end by a projecting flange a¹

page_text: and at the other end by a thicker tubular piece b, which latter has a length of say
5 millimetres equal to the prescribed distance of the cords from the wall.
This distance-piece, which in consequence of the material chosen for its manu-
facture also serves as an insulator, is connected to the lead-cord by means of the
woven covering e of the latter, and is held with the lead-cord in the annular
groove a by the two edge portions a' b, so that the distance-piece, after having been
woven in, cannot be removed from the cord.
b
The tubular piece & designed to act as a distance-piece may be made of any other
form for example, as shown in Figs. 4 and 5, of the form of a disc 61 of a larger
diameter than that of the flange ¹, or, as shown in Figs. 6 and 7 of the form of
an elongated plate 2 whereby also a better support of the distance-piece upon the
wall is thus produced.
The bipartite distance-pieces, which facilitate the weaving-in, consist of a
tubular part with a flange alat und end, and a short tubular part 6, which is
made in height equal to the prescribed distance of the lead from the wall, and has
an inner diameter of such size as to allow of its being slipped upon the tubular
part a.
The connexion of the two tubular parts by glueing or other means is effected
culy after the longer part has been woven into the lead-cord c.
According as the tubular part serving as a distance-piece has the shape of a
sleeve (Fig. 9) of a ring 4 (Fig. 10), or of a rectangular perforated plate 65
(Fig. 11), the two connected parts a and b have the same external shape as the
corresponding integral distance-pieces shown in Figs. 3, 4, and 6, and the annular
recess which serves for the reception of the leads and which is formed between the
flange or annular bulge a and the tubular part 3, or 4, or 5 slipped over the
same, corresponds to the groove a in the integral distance-piece.
In addition to the shapes and materials mentioned, others can also be employed,
the only point as regards form that needs to be considered being that the part that
determines the distance of the lead-cord from the wall is preferably made of such
a contour as to cover the lead-cord, whilst as regards the material it should be noted
that in bipartite distance-pieces the tubular part that is slipped over the insulating
tube and determines the distance of the lead cord from the wall, may be made of
material different from that of the insulating tube.

Improvements in Electric Conducting Cords, and Means for Connecting
them to Walls and other Supports.
We, MÓR KÁROLY PERCI, and FRIGYES SCHACHERER, Cable Manufacturers, both
of Budapest VIII, Szigony-ut, 21, Hungary, 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:- -
The fixing of the conducting cords of electric-light leads in dwellings by the
direct attachment of the cords to the walls which has heretofore been usual, has
been found to be inadmissible from the point of view of safety.
It has, therefore, been prescribed that the leads shall be arranged and fixed freely
suspended at a distance away from the wall.
The means that have heretofore been proposed for carrying out this mode of
fixing are unsuitable either for aesthetic reasons or because the use of such means

page_text: unavoidably damages the paint or paper on the walls and the manner of fixing is
troublesome.
Now the present invention relates to a means for fixing the leads, which conforms
in every respect with the above mentioned regulation and moreover does not spoil
the appearance of the leads.
These means consist of distance-pieces, which also serve as insulators, and the
essence of the invention consists in weaving these distance-pieces in the covering
whilst the said covering is being woven around the conducting wires, with the
result that the said distance pieces are firmly and securely connected to the con-
ducting-cord and enable the latter to be quickly and firmly fastened at the required
distance from the wall.
These distance-pieces each consist of a sleeve or piece of tube made of one or two
parts and composed of insulating material such as bone, celluloid, hard rubber,
wood, etc. This sleeve or piece of tube is formed, in the first case, with a groove
in which the conducting wires are placed and in which they are held by the woven
covering; whereas the bipartite sleeve is composed of two sleeves one of which
slipped over the other, which are of unequal length, and the longer one of which
has a projecting edge or rim portion between which and the shorter tubular piece
the wire leads are placed to be afterwards woven around together with the distance-
piece.
The drawings filed with our Provisional Specification represent several examples
of distance-pieces of this kind.
Figs. 1 and 2 are respectively a side elevation and a front elevation of a con-
ducting cord fixed to a wall by means of a distance-piece of this kind; and
Fig. 3 is a section showing the integral distance-piece employed therein.
Figs. 4 and 5 are respectively an elevation and a plan of another example of
integral distance-pieces; and Figs. 6 and 7 are similar views of a further example.
Figs. 8 and 9 are sections of the two parts (separated from each other) of a
bipartite distance-piece similar to that shown in Fig. 3; whilst Figs. 10 and !!
show two modified forms of bipartite distance-pieces.
As shown in Figs. 3 to 7, the integral distance-piece consists of a tubular piece
having an annular groove a which is limited at one end by a projecting flange or
bulge al and at the other end by a thicker tubular piece b, which latter has a length
of say 5 millimetres; equal to the prescribed distance of the cords from the wall.
This distance-piece, which in consequence of the material chosen for its manu-
facture also serves as an insulator, is connected to the lead cord by means of the
woven covering c of the latter, and is held with the lead cord in the annular
groove a.
by the two edge or rim portions al b, so that the distance-piece, after
having been woven in, cannot be removed from the cord.
C
The tubular piece b designed to act as a distance-piece may be made of any other
form-for example, as shown in Figs. 4 and 5, of the form of a disc of a larger
diameter than that of the flange a, or, as shown in Figs. 6 and 7, of the form of
an elongated plate 62 whereby a better support of the distance-piece upon the wall
is produced.
The bipartite distance-pieces, which facilitate the weaving-in, consist of a tubular
part a with a flange a at one end, and a short tubular part 63, which is made in
height equal to the prescribed distance of the lead from the wall, and has an inner
diameter of such size as to allow of its being slipped upon the tubular part a.
The connexion of the two tubular parts is effected by glueing or other means
after the longer part a has been woven into the lead-cord.
According as the tubular part serving as a distance-piece has the shape of a
sleeve b3 (Fig. 9), of a ring b (Fig. 10), or of a rectangular perforated plate 65
Fig. 11), the two connected parts a and b have the same external shape as the
corresponding integral distance-pieces shown in Figs. 3, 4, and 6, and the annular
recess, which serves for the reception of the leads and which is formed between the
flange or annular bulge a' and the tubular part 63, or 6 or 65 slipped over the same,
corresponds to the groove a in the integral distance-piece.

page_text: In addition to the shapes and materials mentioned, others can also be employed,
the only point as regards form that needs to be considered being that the part that
determines the distance of the lead-cord from the wall is preferably made of such
contour and size as to be covered or concealed by the lead cord, whilst as regards
the material it should be noted that in bipartite distance-pieces the tubular part
that is slipped over the insulating tube and determines the distance of the lead cord
from the wall, may be made of material different from that of the insulating tube.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. A distance-piece for fixing an electric lead at a determined distance from a
wall, consisting of a tubular piece of insulating material which is provided with
an annular groove a for the reception of the wire leads that are to be united with
the distance-piece by weaving and which has at one end an annular bulge or
flange a¹, and at its other end an enlarged tubular, disc-shaped, or plate-shaped
part b, b1, or 63, of a height equal to the desired distance of the conductor from the
wall.
2. A distance-piece of the kind referred to in Claim 1 but made in two parts
which are connected together after the part serving for insulating purposes has
been woven in the covering of the conducting wires, the last mentioned part being
formed as a tube a with an annular bulge or flange a¹, and the other part, which
serves as a distance-piece, being made as a shorter tubular piece 63, as ring b*, or
as a perforated plate 65, and being adapted to be slipped over the tube a, and serving
to hold the woven-in conductor firmly between it and the bulge or flange a¹.
3. An electric conducting cord with either an integral or a bipartite distance-
piece woven in the covering that surrounds the conducting wires, the said distance-
piece being of any desired shape and having a height such that it will keep the
conducting cord at the desired distance away from a wall or like support.
4. Distance pieces for fixing electric leads constructed and arranged substantially
as herein before described with reference to and shown in Figs. 1, 2, and 3, in
Figs. 4 and 5, in Figs. 6 and 7, in Figs. 8 and 9, in Fig. 10, and in Fig. 11 of
the drawings referred to.
