I, THOMAS HENRY BROUGH, of 29, Cornbrook Road, Manchester, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
may
This invention relates to an improved lamp shade holder which be
applied to electric incandescent lamps, or other pendent lamps, and has for its
object to provide a holder which can be cheaply manufactured and which allows
the lamp shade to be readily attached to, or detached from, the lampholder.
The invention consists in providing a springy piece of metal of a U-shape
which is fixed at its centre upon the lampholder or other suitable fitting forming
part of the shade support, with its sides concentric with the lampholder and its
ends provided with suitable projections to form supports for the shade when in
position.
In carrying the invention into effect according to one modification as applied
to an electric incandescent lampholder of the well known "Ediswan," or other
similar type of fitting in conjunction with which a conical shade is used, a
suitable piece of flat springy metal is bent into a U shape and a hole formed in
it at its central part so that it may be slipped on to the socket of the lamp-
holder and suitably secured thereto. The sides of the U shaped clip thus formed
may be slightly curved so as to lie concentric with the cylindrical socket and
Each end
they may be suitably corrugated to give sufficient lateral stiffness.
of the clip is turned outwards so as to form supporting ledges for the lamp shade
which is provided with a hole at its apex so that it can be slipped over the clip.
Each side of the clip may be provided with two slits and the central part bent
upwards so as to form abutments for the top of the lamp shade.
By simply pressing the springy sides of the clip or holder it yields sufficiently
to allow the lamp shade to be slipped into position over the outwardly projecting
ends, in attaching it to, or detaching it from, the lampholder. In order to
ensure an absolutely secure holding of the lamp shade when in place, in some
cases, a projection is formed on each side of the lamp socket and, in fixing the
shade holder or clip it is turned round so that these projections pass under the
sides of the clip forcing them into close contact with the shade. Instead of the
projections on the socket the bayonet joint projecting pins provided on the cap
of the incandescent lamp may be employed to effect the same purpose.
It is obvious that this clip or shade holder can be readily fixed upon existing
incandescent lamp fittings at a very small cost as it can be clamped upon the
fitting by means of the milled nut screwed upon the socket, which is at present
employed or the clip may be provided with a collar round the central hole, and
screwed into position on the socket of the lamp holder.

shades than the conical form of shade.

I, THOMAS HENRY BROUGH, of 29, Cornbrook Road, Manchester, in the County
of Lancaster, 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:-
-::
This invention relates to an improved lamp shade holder which may be
applied to electric incandescent or other pendent lamps; and has for its object
to provide a shade holder or suspending device which can be cheaply manu-
factured and which enables the lamp shade to be readily attached to, or detached
from the lamp holder socket or fitting.
According to this invention a metal clip is constructed having spring sides
which pass within the aperture of the lamp shade and engage with the edge
thereof, the two extremities of the clip being provided with outwardly project-
ing ledge supports upon which the shade rests. The clip is formed with a central
aperture so that it can be slipped over the lamp socket or fitting to which it is
secured by means of a clamping nut or in any suitable manner.
In the accompanying drawings:-
Figure 1 is a view of the improved shade holder or suspending device;
Figure 2 shows the device applied to an electric incandescent lamp fitting and
supporting a bell shaped shade; and
Figure 3 illustrates the device supporting a conical shade.
Referring to these figures, the shade holder or clip constructed from a sheet
metal blank and is provided with spring sides 6 the extremities of the lower
parts of which are provided with outwardly projecting ledges d upon which
the shade rests when in position. The central part of the clip is formed with
an aperture e so that it can be slipped on to the lamp socket and secured thereto
by means of the clamping nut f. The parts c of the clip are curved so that they
lie concentric with the lamp-holder and fit the circular aperture of the lamp
shade.
In fitting or detaching a lamp shade it is only necessary to press the spring
sides of the clip when it yields sufficiently to enable the shade to be passed
over the projections d. In Figures 1 and 2 these projections are turned at right
angles to the parts c so as to fit the horizontal surface adjacent to the aperture
of the shade; but in applying the clip to a conical shade these projections are
inclined to the axis as shown in Figure 3. In order to prevent the shade from
becoming accidentally detached, due to shock or vibration, projections may be
provided upon the lamp socket which can be brought into engagement with the
inside of the clip by turning it round upon the holder after the shade has been
placed in position. In Figure 3 the pins g, attached to the lamp cap and
forming part of the usual bayonet joint, are employed for this purpose. The
shade holder or supporting device can be applied to existing electric incandescent
lamp fittings without necessitating alteration of the fittings or their attachments

the clip in position.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
-
1. A. shade holding or suspending attachment for electric incandescent lamp
fittings consisting of a clip having spring sides adapted to engage with the shade,
substantially as herein before described and illustrated in the accompanying
drawings.
