PROVISIONAL SPECIFICATION.
Improvements relating to the Fixing of Insulating Devices on Walls
or the like.
I, HERMANN KÖTTGEN, of the Firm of H. Köttgen & Co., of Paffrathesstrasse, i,
Berg. Gladbach, Rhine Province, in the Empire of Germany, Manufacturers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved device for fixing insulators for electric
wires, and other objects on walls or the like.
The hitherto used pegs of cast-iron with flat or ribbed foot have the inconve-
nience, that a large hole must be made in the wall, and that the large quantity
of plaster of Paris used for fixing the pegs dries very slowly:
Thus the peg turns easily when the wires are mounted while the plaster is not
yet dry. When the conductor is taken away the wall is also much injured by
the removal again of the pegs. All these inconveniences are avoided by the pre-
sent invention.
The pegs consist of non-oxydizable material, for instance, an easily melting
metal-alloy. They are prismatic and provided with transverse grooves, so that
they can be inserted in proportionally narrow holes in a wall and fixed securely
with a little plaster. Two pegs are put in at a distance corresponding to the two
holes of a conveniently punched surface plate, on which the insulators lie. A
thin sheet of cardboard or the like can be placed between the insulators and the
plate in order to obtain a better support and to avoid the cracking of the insu-
lators.
The insulators are fastened by screws, and inserted into the pegs.
The holes used for fixing the pegs need be only a little larger than required by
the form of the pegs. Therefore a little plaster will be sufficient for fastening,
and consequently the plaster dries very quickly, and a cable or wire can be put
up in a very short time.
Solidity is obtained by means of the use of two pegs and the plate.
The insulators fixed in the pegs or on this device, can be easily taken off again
and replaced by others. The screws, as the hole is closed behind, remain entirely
free of plaster and dampness and do not therefore oxydize in their holes in the
pegs.
After removal of the screws, insulators, and plate, the pegs can remain in the
wall and will not be visible if covered by painting or wall-paper. When the
pegs are used singly the plate is not used and then if desired a round washer can
be used in place thereof.

I, HERMANN KOTTGEN, of the Firm of H. Kottgen & Co., of Paffratherstrasse 1,
Berg. Gladbach, Rhine-Province, in the Empire of Germany, Manufacturer, 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 an improved device for fixing insulators for electric
wires and other objects on walls or the like.
The hitherto used pegs of cast-iron with flat or ribbed foot have the inconve-
nience, that a large hole must be made in the wall, and that the large quantity
of plaster of Paris used for fixing the pegs dries very slowly.
Thus the peg turns easily when the wires are mounted while the plaster is not
yet quite dry. When the conductor is taken away, the wall is also injured by the
removal of the pegs. All these inconveniences are avoided by the present inven-
tion.
In the annexed drawings:-Fig. 1 is a plan view of the improved device.
Fig. 2 shows the peg in end view. Fig. 3 is a longitudinal section through the
peg with the fixing screw.
The pegs a and b consist of non oxydizable material for instance an easily
melting metal alloy. They are hexagonal in section and provided with trans-
verse grooves so that they can be inserted in proportionally narrow groove H in
a wall and fixed securely with a little plaster. The two pegs are put at a dis-
tance corresponding to the two holes of a conveniently punched surface plate c,
on which the insulators d and e lie. A thin sheet of card board or the like
can be placed between the insulators and the plate e, in order to obtain a better
support and to avoid the cracking of the insulators.
The insulators d and e are fastened by screws ƒ and g inserted into the
pegs a and b.
The holes for fixing the pegs need be only a little larger than required by
the form of the pegs. Therefore a little plaster will be sufficient for fastening.
and consequently the plaster dries very quickly; and a cable wire can be put
up in a very short time.
Solidity is obtained by means of the use of two pegs and the plate c.
Besides the solidity, durability and small expense this new manner of fixing has
also further advantages.
The walls are not so damaged since only small holes are required for fastening
the single pegs.
The device is fixed in a very short time, whilst the hitherto used iron pegs
became fixed only very slowly on account of the large quantity of plaster required
and wire thus easily loosened by premature use; wooden pegs become always loose
by the shrinking of the unseasoned wood.
The insulators fixed in the pegs or on this device, can be easily taken off again
and replaced by others.
The screws, as the hole is closed behind, remain entirely free of plaster and
damp and do not therefore oxydise in their holes in the pegs.
After removal of the screws, insulators and plate, the pegs can remain in the
wall and will not be visible if covered by painting or wall paper.
When the pegs are used single, the plate c is not used and then if desired a
round washer can be used in place thereof.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is:-
An improved method for fixing insulators on walls or the like in which hori-
zontal or many sided pegs of non oxydizable metal alloy are provided with trans-
verse grooves and serve either singly or in pairs connected by a plate for receiv-
ing the screws fixing the insulators and plates such pegs being fixed with plaster
or the like in the wall and the whole being kept together by the screws engaging
with the pegs.
