PROVISIONAL SPECIFICATION.
Improvements in Detachable and Swivelling Electric Light Fittings.
JOHN FREDERICK WAKELIN, Electrical Engineer, 33, Robert Street, Regents
Park, London, N.W., CHARLES JAMES WESTON, Electrical Engineer, 5, Tottenham
Street, London, W, and 20, Lonsdale Square, Barnsbury, N., do hereby declare
the nature of this invention to be as follows:-
Our invention of improvements in detachable & swivelling electric fittings
has for its object to enable a fitting (consisting of reflector or shades, lamp-
holders & lamps with connections for same) to be readily connected, electrically
& mechanically, to a bracket or pendant suitable for outside or other lighting,
and also to be readily disconnected from aame
With thus we combine an arrangement for swivelling the fitting (as described),
in a vertical or horizontal plane, whereby the duection of light may be adjusted.
According to our invention we provide an outer metal case in two halves, united
by a loose ring, and containing any suitable electrical make and break contact
auch as a two pin plug and sockets, concentric plug and socket, on studs, mounted
in insulating blocks.
The one half of case and loose 11ng 18 attached to the bracket on pendant, the
other half has attached to it a swivelling airangement in the form of a bariel
hinge. The fitting (as described) is attached to a tube screwed into the inner
rotating part of hinge, and working through a slot in the outer case.
Two nuts clamp the hinge in any required position, and two pins in rim of
lower half of case, fitting into recesses in upper half, ensure a fixed position
relative to one another
CLAIMS.
(1) The combination with an electric bracket or pendant of a fixed upper
and detachable lower half case, with an electrical make and break contact, sub-
stantially as described.
(2) The combination with the above of a barrel hinge with suitable passages
for electrical connections, to which is attached a fitting (as described), and
capable of adjustment in a vertical or horizontal plane, and also of being fixed
in a required position, substantially as above described.

[Prace 8d.1

page_text: of 20, Lonsdale Square, Bainsbury, N, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertamed in and by the following statement:
This invention relates to the consti uction of electric light pendants & brackets
in such a manner as to allow of a fitting, comprising reflector, lampholders, &
lamps with connections for the same, to be readily connected, electrically and
mechanically, to the fixed part of a pendant or bracket, suitable for outside
lighting, and also to be readily disconnected from the same
The accompanying drawing is a vertical section for a bracket
a a is the hxed half of a metal case, screwed for attachment to a bracket.
is a disc of maulating material, in which are mounted two sockets 3 8 with
terminals for attachment of conductors at the back of r.
bis the other half of metal case, in which is fixed a similar insulating
block,, with two plugs P p mounted on it to correspond with sockets 38
The plugs pp have terminals at back of the block for conductors to lamps.
The loose ing unites the two halves by a bayonet catch as shewn, or by
BC1ewing on to b b
To is attached the reflector, lampholders, and lamps For use with conical
shades having openings greater than 2 (two inches and a half) we make the
shade carrier c c, detachable from the back, allowing the shade to be replaced
without unwiring the fitting We may however, mount any other form of
reflector on b b.
Where the lamps on a fitting are on more than one switch, we add one or more
plugs and sockets, in which case the feed conductor is taken to one plug and
corresponding socket, the switch wires being taken to the other plugs and
Bockets
To allow of adjustment in a vertical plane we may interpose a barrel hinge
between bb and the lampholders, with openings for the conductors, allowing the
lamps to be swivelled through a small angle.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is performed, we declare that what we
claim is
-
The combination with a pendant or bracket of a detachable fitting, with
plug and socket terminals, as described
2 The combination, in a detachable fitting of the reflector with the detachable
part of the connections, lampholders and lamps, allowing removal of same from
the bracket or pendant.
