Improvements in Lamp Irons Applicable to the Suspension of
Electric Fittings.
I, JOHN BLACK MEIKLEJOHN, of 5, Gordon Terrace, Shettleston, in the County
of Lanark, North Britain, Electrical Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in lamp irons or hanger for electrical
fittings and has for its object to construct these in such a manner as to enable the
joints of wires to be all made at top of fitting so as to facilitate the erection of
electric fittings.
In carrying out my invention I make one or more openings at the lower end of
the lamp iron or hanger through which the wires pass and round the outside of
which the joints are made. A ceiling plate is then put on which covers joints and
on lower end of tube there is screwed à nozzle for cord fittings, hook, coupling or
other connection.

Improvements in Lamp Irons Applicable to the Suspension of
Electric Fittings.
I, JOHN BLACK MEIKLEJOHN, of 5, Gordon Terrace, Shettleston, in the County
of Lanark, North Britain, Electrical Engineer, 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:-
My invention relates to improvements in lamp irons or hangers for electrical
fittings and has its object to construct these in such a manner as to enable the
joints of wires to be made at top of fitting at ceiling so as to facilitate the erection
of electric fittings, and in the case of fire-proof floors to keep them fireproof by
grouting up lamp irons with cement.
In carrying out my invention I make one or more openings at the lower end of
the lamp iron or hanger through which the wires pass and outside of
which the joints are made. On the lower end of said tube, there is screwed an
attachment with cord grip hook coupling or other connection. The joints are
then made and the ceiling plate or boss lifted up into the position and held in
position by screwed ring.

page_text: In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawings, of which,
Figure 1 is a vertical section of a lamp iron or hanger with cord grip and roof
plate fixing.
Figure is a similar view to Figure 1 illustrating an arrangement of coupling
fixing.
Figure 3 is also a similar view to Figure 1 with a hook attachment, and
Figure 4 is a vertical section of an abridged form of lamp iron with ceiling plate
or boss adapted for use with wiring in casing on ceilings or tubes ou ceilings and
otherwise all as above.
The lamp iron or hanger is indicated by the letter A. In its lower end open-
ings B and B being provided in order to allow of the ends C and D of the
wires E and F being jointed. This is effected by fixing attachment or fitting on
end of lamp iron making joints in wire then lifting ceiling plate up in position,
which plate or boss is held in position by screwed ring.
In all the figures the ceiling plate or boss H rests with its lower surfaces on the
screwed ring G. The rod of fitting I illustrated in Figure 2 is suspended by a
flange J, which rests upon the seat G2 formed within the hollow of coupling G or
may be made similar to ball joint of gasaliers. In Figure 3 the fitting G terminates
with the hook extension G³ through the stem of which a hole G is made which
allows the wires F to pass through.
If the pipe M be made of wrought iron tubing the lamp iron shown will be
done away with and the pipe bend extended down through ceiling and have holes
in lower end, as shown in dotted lines Figure 1 of the drawings, adapted for
fittings aforesaid.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
-
In lamp irons or hangers, constructing these in such a manner as to enable the
joints of wires to be made at top of fitting at ceiling, so as to facilitate the erection
of electric fittings and in the case of fireproof floors to keep them fireproof by
grouting up lamp irons with cement, substantially as described and illustrated on
the accompanying sheet of drawings.
