PROVISIONAL SPECIFICATION.
Improvements in or relating to Fittings for Electric and other
Lamps.
I JOSEPH CLIFT of "Steindach," Dorking in the County of Surrey, Chemist,
do hereby declare the nature of this invention to be as follows:-
My invention has reference to certain improvements in or relating to the
construction and arrangement of fittings for electric and other lamps and has for
its objects, firstly to fix the glass shade covering the lamp in such a manner that
no shadow will be cast and that it can be readily removed when required for any
purpose; secondly, to so construct and arrange the reflector that its reflecting
surface can be readily removed wholly or in part as required.
To attain my first object I form a suspending flange round the open top of the
glass shade and upon the inner surface of the reflector in suitable positions I fit
two or more fixed holders for the flange and one or more swivelling catch hooks or
other flange holders of suitable shape: by operating the latter the glass shade can
be removed or refixed instantly and no shadow is cast by the devices. The above
may be fitted to any kind of reflector or top plate.
To attain my second object I line the reflector cover or plate with a number of
suitably shaped close fitting segments of silvered glass tin or other equivalent
reflecting material, each such segment is removable and is held at its inner end
(around the centre of the reflector) in a rim or holder, and at its outer end at each
of its corners or centrally by a screw and nut, set screw, button, or swivelling
holder or other device or devices mounted on or near to the periphery of the
reflector cover and capable of being moved to hold or release as required any or
all of the reflecting segments.
Parts of the said sections are removed to admit of
the passage of the shade holders when used in combination. The reflector cover
is of any suitable material such as metal papier maché, wood or the like and it may
be dished, flat, or polygonal the holders of the reflecting sections being arranged
either at the corners or centrally as most convenient.

Improvements in or relating to Fittings for Electric and other
Lamps.
1 JOSEPH CLIFT of "Steindach," Dorking in the County of Surrey, Chemist
do hereby declare the nature of this invention and the manner in which the same
is to be performed to be particularly described and ascertained in and by the
following statement :--
My invention has reference to certain improvements in or relating to fittings
for electric and other lamps and has for its objects, firstly to fix the glass shade
covering the lamp in such a manner that no shadow will be cast, and that it can be
readily removed when required for any purpose; secondly, to so construct and
arrange the reflector that its reflecting surface can be readily removed wholly or in
part as required.
I will now fully describe my invention in reference to the accompanying drawings
in which
Figure 1 is a half elevation and half vertical section, and Figure 2 a half plan
and half inverted plan of my improvements applied to an electric lamp fitting.

page_text: Similar letters refer to similar parts in both figures.
A is a glass shade covering and protecting the electric glow lamp A', around
the top of the glass shade A I form a suspending flange a. B is the reflector plate
which may be of any suitable material such as metal, wood or the like, and of the
conical shape illustrated, or dished, flat, polygonal or otherwise according to
requirements.
Upon the inner surface of said reflector plate B I fit two or more fixed holders
such as 6 adapted to fit and hold the flange a of the glass shade A in its position as
shown.
I also provide one or more hooks, clips or holders & also fitting the said shade
flange and capable of swivelling motion upon a centre 62; by operating which the
shade A may be removed or refixed easily and quickly for cleaning or otherwise
as required and no shadows are cast by the devices.
The above may be fitted to any kind of reflector plate whether situated above
the lamp as illustrated or otherwise.
To attain my second object I line the reflector plate B with a number of suitably
shaped close fitting pieces of silvered glass, tin or equivalent reflecting material
such as C. In case of a circular reflector plate as illustrated the pieces would be
sectors as shown, and each such sector or section is removable and held in position
at its inner end either by a continuous rim such as c, or by independent holders
fixed at suitable intervals.
The outer ends are held by a number of clips or holders c¹ situated either at the
several joints of the sections of reflecting material as illustrated in such manner
that one holder will suffice to hold two adjacent corners, or otherwise in convenient
positions; the clips or holders c' are centered on the outside of the reflector plate
at and capable of swivelling motion thereon; or for each sector a central screw
and nut, set screw, button, swivelling holder, or equivalent device, and capable of
being moved to hold or release as required any or all of the reflecting sections may
be arranged.
Parts of the said sections of reflecting material C are removed as at c³ to admit
of the passage of the shade holders b when used in combination.
In case of breakage or damage to any section or sections of reflecting material,
such damaged section can be easily and readily removed by operating the outer
moveable clips or holders c¹ and a new one substituted in its place, and cleaning is
performed in a similar manner.
Having now particularly described and ascertained the nature of this inven-
tion and the manner in which the same is to be performed I declare that what I
claim is:-
1. In a fitting for electric and other lamps, the combination with a reflector
plate provided with fixed and moveable holders such as . b of a Hanged glass
lamp shade or cover substantially as and for the purposes set forth.
2. In a fitting for electric and other lamps the combination with a reflector
plate of reflecting material made and fitted in several sectors or parts, said plate
being provided with fixed and moveable holders for same, substantially as and for
the purposes set forth.
3. In a fitting for electric and other lamps, the combination with a reflector
plate of fixed and swivelling clips bb and flanged lamp cover A, sectional reflecting
material, and fixed and moveable holders for same, all arranged and combined
substantially as and for the purposes described and illustrated.
