PROVISIONAL SPECIFICATION.
Improvements in Means for Connecting or Supporting Electroliers,
Brackets for Electric Lamps, or the like to or from Ceilings,
Walls, or other Places of Support.
I, HENRY EDMUNDS, of 39 Victoria Street, in the City of Westminster,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to provide means whereby electroliers, brackets
for electric lamps, or the like, can be connected to, or supported from, ceilings,
walls or other supports, with great facility security, and neatness, the mechanical
connection, or attachment, of the electrolier, or the like, being made at the same
time as the electrical connections are established. According to my invention
I provide at the part of the ceiling, or wall, or other place, to which the fitting is
to be attached, a holder, or supporting piece, provided with a fastening device for
the mechanical connection of the electrolier, or the like, and with contact pieces in
connection with the lead wires for the electric current. The electrolier, or the
like, is provided with a corresponding fastening device for the connection of the
electrolier, or the like, and with corresponding contact pieces to which the wires
leading to and from, the lamp, or lamps, are connected the arrangement being such
that as the parts for the mechanical connection are being secured together the
respective contact pieces are also brought together and the mechanical and
electrical connection simultaneously effected.
The following is a convenient arrangement according to my invention:-In the
ceiling, or wall, or other place, I imbed a box of insulating material containing
contact pieces to which the lead wires are respectively connected the said contact
pieces consisting of a centre pin connected with the one wire and surrounding tube
connected with the other wire. These contact pieces are situated opposite a
screwed hole in the outer side of the said box. The electrolier, or the like, is
provided with a screw at its base which screws into this screwed hole and the said
screw has within it contact pieces formed of two tubes, insulated from each other,
one to pass over the pin and the other to pass into the tube constituting the contact
pieces in the aforesaid box.
The contact pieces within the screw of the electrolier, or the like, are
respectively connected to the wires to, and from, the lamp. When the electrolier,
or the like, is to be secured in place its screw is screwed into the screwed hole in
the box in the wall, ceiling, or other place, and, at the same time, the contact pieces
in the electrolier, or the like, engage with, or bear on, those in the said box, and
the mechanical connection of the electrolier to the wall, or the like, and the
establishment of the electrical contact necessary for making the circuit, are
simultaneously and securely effected.

1 HENRY EDMONDS of 39 Victoria Street in the City of Westminster,
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 has for its object to provide means whereby electroliers, brackets
for electric lamps, or the like can be connected to, or supported from, ceilings,
walls or other supports with great facility, security and neatness, the mechanical
connection, or attachment, of the electrolier, or the like, being made at the same
time as the electrical connections are established. According to my invention
I provide at the part of the ceiling, or wall or other place, to which the fitting is
to be attached, a holder, or supporting piece, provided with a fastening device for
the mechanical connection of the electrolier, or the like, and with contact pieces in
connection with the lead wires for the electric current. The electrolier or the
like, is provided with a corresponding fastening device for the mechanical
connection of the electrolier, or the like and with corresponding contact pieces to
which the wires leading to and from the lamp, or lamps, are connected, the
arrangement being such, that as the parts for the mechanical connection are being
secured together the respective contact pieces are also brought together and the
mechanical and electrical connection simultaneously effected.
The following is a convenient arrangement according to my invention which
I will describe with reference to the accompanying drawing.
Figure 1 being a vertical section of the attachment for the ceiling, wall or
the like.
Figure 2 a vertical section of the attachment for the electrolier or the like.
Figure 3 a similar section of the two parts secured together and
Figure 4 an inside plan shewing the electric contacts of the attachment for the
ceiling wall or the like.
In the ceiling or wall, or other place or in a recess therein I secure or imbed a
box A of insulating material containing contact pieces to which the lead wires are
respectively connected the said contact pieces consisting of a centre pin b of metal
connected by the metal piece 62 with the one lead wire c and a surrounding metal
tube d connected by the piece with the other lead wire c³.
The said box A is secured within the outer casing A' by the screws a and in this
outer casing A' is a female screw thread for the mechanical attachment of the
electrolier or the like which is provided with a screw on its base piece B³ which
screws into this screwed hole in the casing A' and the said screw piece B* has
secured within it by the screws e a box B carrying contact pieces ƒ and g each
formed of a metal tube which tubes are insulated from each other, one to pass over
the pin b and the other to pass into the tube d constituting the contact pieces in the
aforesaid box A.
The contact pieces f and g within the screw of the electrolier, or the like, are
respectively connected to the wires h h³ to, and from, the lamp, the tube f being so
connected by the pin and plate and screw and the tube 9 being so
connected by the ping plate gand screw 9. When the electrolier or the like
(the base part only of which is shewn) is to be secured in place its screw is screwed
into the screwed hole in the box or casing A' in the wall ceiling or other place
and at the same time the contact pieces ƒ and g of the electrolier, or the like
engage with or come into contact with the contact pieces 6 and d in the said box A
the mechanical connection of the electrolier to the wall or the like and the

page_text: -
establishment of the electrical contact necessary for making the circuit, are
simultaneously and securely effected.
E is an india rubber ring which is compressed when the parts are secured
together, and by this a bracket can be placed upright however the screws may be
cut and the pressure exerted by it holds the bracket firmly in position. I do not
limit myself to the use of screws as the mechanical fastening nor to the precise
form of the electrical contact pieces shewn.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. For connecting or supporting electroliers, brackets for electric lamps or the
like to, or from, ceilings walls or other places of support providing in the ceiling
wall or other place a holder or supporting piece provided with a fastening device
for the mechanical connection of the electrolier bracket or the like and with
contact pieces in connection with the lead wires for the electric current and
providing the electrolier bracket or the like with a corresponding mechanical
fastening device and contact pieces connected to the wires of the lamp or lamps so
arranged that when the mechanical attachment is made the electrical circuit is also
completed substantially as hereinbefore explained.
2. A connection or support for electroliers, brackets for electric lamps or the like
consisting of the arrangement and combination of parts substantially as hereinbefore
described and illustrated in the accompanying drawings.
