This invention relates to an insulating-cleat for supporting conducting-wires for
electrical-circuits; and it consists of a cleat composed of porcelain, glass, or other
material that is a non-conductor of electricity, made substantially in the form
shown in the accompanying drawing and adapted to be secured to any part of a
building without danger of fire from the electric current passing through the wires
connected to, or carried by, said cleat.
In the drawing, A indicates our insulating-cleat, which consists of a central
body, 1, perforated vertically for receiving a fastening-screw, B, which secures
said cleat in position. The upper end of said body should have a broad bearing
to give the cleat stability. At each end of said body, a hook, 2, is formed so that
its terminal, 3, will range in line, or approximately so, with the upper face of the
body, 1. Between said body and each hook, a slotted opening, 4, is formed;
preferably said opening inclines outwardly toward the corresponding end of the
cleat, and, preferably, said openings are extended horizontally to form a shoulder, 5,
on each hook, and said shoulders for landings to prevent the wires from slipping
from said openings. Preferably the upper face of the body 1 is provided with
spurs, 6, which indent the surface to which the cleat is attached and prevent the
cleat from being turned from its position by a strain of the attached wires.
C designates wires for conducting electric currents, and said wires are held by
our cleat, either by passing the wires through an opening 4, to lie upon a hook 2,
or by a hitch, 7, formed by looping the wire around the hook. By fastening the
wire as last described, the cleat A is supported to retain it against the strain of
the wire. In practice the fastening last described need not be made on every
cleat, but it may be employed at points desirable for obtaining efficiency.
By constructing our cleat with a central body a sufficiency of non-electric
material is interposed between the wire C and screw B to secure a perfect
electrical-insulation of said parts from each other.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is―
1. A cleat for conducting-wires, composed of non-electric material and con-
sisting of a central body, 1, whose upper face will bear directly against a plane
and is perforated to receive a screw, B, that will be surrounded by the insulating
material to the point of contact of the cleat with said plane; said central body
having at each end a hook, 2, integral therewith and provided with a terminal, 3,
ranging either positively or approximately-with the upper face of the central
гр

page_text: body whereby slotted openings, 4, with practically parallel sides are formed
between said body and hooks, as specified.
2. A cleat for conducting-wires, composed of non-electric material and con-
sisting of a central body, 1, whose upper face will bear directly against a plane
and is perforated to receive a screw, B, that will be surrounded by the insulating
material to the point of contact of the cleat with said plane; said central body
having at each end a hook, 2, integral therewith and provided with a terminal, 3,
ranging either positively or approximately-with the upper face of the central
body; whereby slotted openings, 4, with practically parallel sides are formed to
extend-first downwardly inclined and then horizontally-from said body to form
shoulders, 5, in said openings, as specified.
3. A cleat for conducting-wires, composed of non-electric material and con-
sisting of a central body, 1, whose upper face will bear directly against a plane
and is perforated to receive a screw, B, that will be surrounded by the insulating
material to the point of contact of the cleat with said plane; said body having at
each end a hook, 2, whose terminal, 3, ranges-either positively or approximately-
with the upper face of said body; whereby slotted openings, 4, with practically
parallel sides are formed between said hooks and body, in combination with a
conducting-wire, C, secured to said cleat by a hitch, 7, of said wire around a hook
of the cleat, as specified.
