PROVISIONAL SPECIFICATION.
Improvements connected with Shades and Shade or Reflector
Holders for Incandescent Electric Lamps.
I, RICHARD ROBERT HARPER, of Sash Court, Wilson Street, Finsbury in
the County of London, Electrical Engineer, do hereby declare the nature of
this invention to be as follows:-
:-
This invention relates to certain improvements connected with shades and shade
or reflector holders for incandescent electric lamps.
For the purpose of this invention, I make a clip for encircling the lamp socket
or holder," said clip being adjustable and affixable in any desired position by a
pinch screw.
The face edge of the clip plate has a couple, or other number of headed studs
for the shade or reflector to be suspended, or otherwise held, said shade or reflector
having a shank or fang with slot holes to fix it to the clip plate. The shades or
reflectors are preferably in such form as to be held to a backing by turn over
points or lips, and the backing has the slots for fixing to the clip plates.
Any curvature can be given to the shade holder to correspond to that of the
shade or the reflector, whether for straight ahead, anglewise, or for downward
deflection, according to the trade, or other purposes or uses to which the lamp is
arranged.

COMPLETE SPECIFICATION.
Improvements connected with Shades and Shade or Reflector
Holders for Incandescent Electric Lamps.
I, RICHARD ROBERT HARPER, of Sash Court, Wilson Street, Finsbury, in
the County of London, 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:-
This invention relates to certain improvements connected with shades and shade
or reflector holders for incandescent electric lamps.
The invention is shown in the annexed drawings.
Figure 1 is an elevation of a curved reflector with the hollow face fronting the
lamp, and with the clip embracing the lamp socket, on which it can be fixed at any
part for reflecting the light in any desired direction.
Figure 2, a part sectional elevation of the clip with the spring holder for
temporarily fixing the reflector in an upright position.
Figure 3, a face view of a reflector, such as made of silvered copper.
Figure 4, a perspective elevation of a single clip for two reflectors.
Figure 5, a back elevation of a reflector, say, silvered glass in a plate frame
provided with rolled side edges for receiving a price, or other card.
Figure 6, a front view of same with a card in position, and as would appear
above the lamp.
The reflectors shown at Figures 1 and 4 if silvered, on both sides can be fitted in
the clips employed either face exposed to the lamp for concentration, or for
diffusion of the light, whether such be used singly, or in pairs, and they can be bent

page_text: to cast the light upwards, or downwards, according to circumstances, and such
reflectors may have price cards, or the like placed on them.
I make a clip A for encircling the lamp socket or "holder" B, said clip being
adjustable and affixable in any desired position by a pinch screw C.
The face edge of the clip plate has one, or a couple, or other number of headed
studs D on springs E for the shade, or reflector F to be held, said shade or reflector
having a shank or fang G with one, or more slot holes H to fix it to the clip
plate 1. The shades or reflectors F, such as of glass, can be held to a backing J
by turn over points, or lips K, K, and the backing has the slot, or holes H for
fixing to the clip plates 1.
Any curvature can be given to the shade holder I to correspond to that of the
shade, or the reflector, whether for straight ahead, anglewise, or for downward
deflection, according to the trade, or other purposes, or uses for which the lamp is
arranged.
The frame J may have rolled edges L, L, for the reception of price or like
cards, which on being slipped in, are stopped by the lips M, M, and have a
portion N projecting above where the glass is employed; the face of the frame J
may be silvered only, or be in conjunction with a glass not silvered, but of a colour
like stained glass for throwing a tint upon the goods which the lamp reflects upon,
or for artistic effect.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim is :-
1. The improvements connected with shades and shade holders for incandescent
electric lamps, as described with reference to the annexed drawings, and shown in
Figures 1, 2, and 4.
2. Affixing to an adjustable clip a spring head for use in conjunction with a
reflector fang with a hole in it, by which the reflector can be held rigidly, and
adapted for the purposes described.
