Improvements in Pendants or Electroliers for Electric Lamps.
We JOHN WEBB SINGER, WALTER HERBERT SINGER and EDGAR
RATCLIFFE SINGER, trading as John W. Singer & Sons, Art Metal Workers,
Frome, in the County of Somerset, do hereby declare the nature of this invention
to be as follows:-
This invention for improvements in pendants or electroliers for electric lamps
has for its object to provide improved means for suspending electric lamps from
ceilings and consists essentially in suspending the lamps from a chain having an
axial hole in each end of the link for the passage of the electric conductors leading
the current to the lamps.
This arrangement dispenses with the usual tube or barrel enclosing the
conductors and allows of the conductors being readily got at.
In one form the chain is made of sheet metal joined up to form a link by
brazing or soldering, two holes being stamped in the blank in such position that
when the link is formed and in place the two holes will be in the axis of the
chain.

Improvements in Pendants or Electroliers for Electric Lamps.
We JOHN WEBB SINGER, WALTER HERBERT SINGER and EDGAR
RATCLIFFE SINGER, trading as John W. Singer & Sons, Art Metal Workers,
Frome, in the County of Somerset, 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 for improvements in pendants or electroliers for electric lamps
has for its object to provide improved means for suspending electric lamps from
ceilings and consists essentially in suspending the lamps from a chain having an
axial hole in each end of the link for the passage of the electric conductors
leading the current to the lamps.
This arrangement dispenses with the usual tube or barrel enclosing the
conductors and allows of the conductors being readily got at.
In one form the chain is made of sheet metal joined up to form a link by
brazing or soldering, two holes being stamped in the blank in such positions that
when the link is formed and in place the two holes will be in the axis of the
chain.
In the accompanying sheet of illustrative drawings
Fig. 1 is an elevation partly in section of two links of a chain pendant constructed
according to this invention and Fig. 2 is a plan of the same.
Figs. 3, 4. and 5 show modified construction of links.

page_text: Referring to Fig. 1, each link a is shown as cut out of sheet metal and joined
up by brazing. Each link is formed with an enlargement 6 at the centre of each
end in which is a central hole c. In the complete chain pendant all the holes
come into line with one another and the electric conductors d are threaded through
the holes and are thus retained in the axis of the chain.
In the modification shown in Fig. 3 instead of soldering the links, the blank is
formed with a central enlargement 6 and two end enlargements b. In the formed
link the two end enlargements are overlapped as shown and secured together by a
tubular rivet or eyelet e. By this arrangement the length of the chain can be
adjusted without destroying a link and a second length of chain can be easily
added if desired, it being necessary only to carry a loose tubular rivet or eyelet e.
This eyelet instead of being a complete tube may be formed out of sheet metal.
Or the enlargements may be secured together by bending two narrow strips over
them preferably opposite to one another and at right angles to the ends of the
link. Or the enlargements may be secured by binding wire.
In the modification shown in the upper part of Fig. 4 and 5 each link blank is
formed with a single central enlargement baud when the link is formed the meeting
ends are turned up as clearly shown at f so that the enlargement 6 of the next
lower link will pass over the ends and hold them in position.” If desired the ends
may then be clinched over it.
In the modification shown in the lower half of Figs. 4 and 5, an open link is
closed by a pivoted catch g. These open links need only be inserted in the pendant
at intervals.
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 pendant or electrolier for electric lamps consisting of a linked chain, each
link having a clear passage in the axis of the chain for the passage of the
conducting wires.
2. A link for a chain pendant or electrolier for electric lamps, in which the
conducting wires pass axially down the chain consisting of a perforated top end,
two side arms, and the two perforated bottoms bent over one another from the
sides and secured together.
3. A link for a chain pendant or electrolier for electric lamps, in which the
conducting wires pass axially down the chain, consisting of a perforated top end,
two side arms, and of the two bent up ends adapted to pass within the hole of the
perforated top of the next lower link.
4. A link for a chain pendant or electrolier for electric lamps, in which the
conducting wires pass axially down the chain, consisting of a perforated top end,
perforated bottom end, one complete side and one open side completed by
a catch.
5. The improvements in pendants or electroliers for electric lamps substantially
as described with reference to the drawings.
