PAUL RAOUL DE FAUCHEUX D'HUMY of Carlton Mansions, Clapham Road in
the County of Surrey IMPROVEMENTS IN INSULATORS FOR TELEGRAPH POSTS
OR OTHER SUPPORTS.
The Invention has for its object improvements in insulators for telegraph posts or
other supports, whereby a more efficient insulation is obtained and provision
afforded for any required number of wires at a comparatively small expense.
For this purpose I bolt or otherwise fix to the post a metal frame or support
which I insulate from the post by the interposition of earthenware, or other
insulators between the frame or support and the post, the surfaces of which
insulators in contact with the post and with the frame or support are preferably
spherical or convex.
The frame or support has at the lower part thereof a bracket which according
to one arrangement is perforated to receive a vertical rod whose lower end is
formed to receive a nut to enable it to be firmly fixed. On this vertical rod are
threaded any required number of earthenware or other insulators each of which is
formed with a central hole and with supports for the wires formed with com-
paratively narrow waists or with grooves around which the wires are passed, the
heads of such supports being sufficiently large to securely hold the wires in
position.
The lowest earthenware or other insulator rests on a block of vulcanite or other
insulating material and a cover of earthenware or other insulating material is
placed over each insulator to deflect rain therefrom. The upper end of the vertical
Doll

page_text: rod is held in any convenient manner, but I prefer to do so by means of a hook
or catch threaded thereon which hook or catch takes into an eye or other shaped
fixture on the metal frame or support. I cover the upper end of the vertical rod
with a head piece or cap of earthenware or other insulating material.
According to another arrangement the metal frame or support and the bracket
at the lower part thereof and a bracket or support at the upper part are employed
to support a slab of earthenware or other insulating material formed with a number
of perforations therein through each of which a wire is passed and I preferably
form bosses or projections on each side of such perforations in order to afford extra
support for the wires and to protect them from contact with moisture on the
surface of the slab. I also form or mount on the upper edge of the perforated slab
a roof or cover to protect it from rain and on the upper edge of such roof or cover
I form grooves or sockets for receiving other wires. If desired the perforated slab
may be provided with lugs or ears by which it may be fixed to the pole or other
support, such lugs or ears being formed with convex projections to come against
the pole or other support.

PAUL RAOUL DE FAUCHEUX D'HUMY of Carlton Mansions, Clapham Road in
the County of Surrey "IMPROVEMENTS IN INSULATORS FOR TELEGRAPH POSTS
OR OTHER SUPPORTS
"
The Invention has for its object improvements in insulators for telegraph posts
or other supports whereby a more efficient insulation is obtained and provision
afforded for any required number of wires at a comparatively small expense.
In all the Figures like parts are marked with similar letters of reference.
For this purpose according to the arrangement represented at Figures 1 and 2
which are respectively a vertical section and an elevation, I bolt or otherwise fix
to the post or other support a a metál frame or support 6 which I insulate from
the post or other support a by the interposition of earthenware or other insulators c
between the frame or support b and the post or other support a, the surfaces of
which insulators c are preferably spherical or convex.
.
The frame or support b has at the lower part thereof a bracket b' which
according to the arrangement now being described is perforated to receive a
vertical rod d whose lower end is formed to receive a nut d' to enable it to be
firmly fixed.
On this vertical rod d are threaded any required number of earthen-
ware or other insulators e each of which is formed with a central hole and with
supports e¹ for the wires f formed with comparatively narrow waists or with
grooves around which the wires f are passed, the heads of such supports e¹ being
sufficiently large to securely hold the wires f in position.
The lowest earthenware or other insulator e rests on a block of vulcanite or
other insulating material g and a cover g₁ of earthenware or other insulating
material is placed over each insulator e to deflect rain therefrom and the insulator g
is of similar form to the covers g¹ in order to deflect rain from the bracket b¹.
The upper end of the vertical rod d is held in any convenient manner but I prefer
to do so by means of a hook or catch d' threaded thereon which hook or catch (
takes into an eye or other shaped fixture 6 on the metal frame or support b.
I cover the upper end of the vertical rod d with a head piece or cap d³ of
earthenware or other insulating material.
According to the arrangement represented at Figures 3 and 4 which are
respectively a side elevation and a cross section the metal frame or support b and
the bracket b' at the lower part thereof and a bracket or support 63 at the upper
part are employed to support a slab h of earthenware or other insulating material
formed with a number of perforations therein through each of which a wire is
passed and I preferably form bosses or projections h' on each side of such
perforations in order to afford extra support for the wires and to protect them
from contact with moisture on the surface of the slab h. I also form or mount on
the upper edge of the perforated slab h a roof or cover h³ to protect it from rain
and on the upper edge of such roof or cover h² I sometimes form grooves or
sockets has shown at Figures 5 and 6 for receiving other wires. If desired the
perforated slab h may be provided with lugs or ears h by which it may be fixed
directly to the pole or other support thereby dispensing with the metal frame or
` support b and in such case the lugs or ears h* are formed with convex projections
or surfaces to come against the pole or other support a thereby preventing the
travelling of moisture from the latter to the slab h."
At Figure 7 I have represented a section through the slab h in which instead
of passing the wires f directly through the perforations I place double hooks or
junctions in such perforations and connect thereto the ends of the wires f.

page_text: At Figures 8 and 9 I have represented a modification in the slab h in which
case instead of passing the wires f through perforations in the slab, I pass them
around knobs or projections standing out therefrom.
Having thus described the nature of my said Invention and the mode in which
I carry the same into effect I would have it understood that what I claim is the
peculiar constructions of insulators for telegraph posts or other supports
substantially as herein shewn and described.
In witness whereof I the said Paul Raoul de Faucheux d'Humy have hereunto
set my hand and seal this Eighteenth day of July in the year of our Lord One
thousand eight hundred and eighty three.
