A New or Improved Reflector or Diffuser, principally applicable
for Photographic Purposes.
FREDERICK JOHN BORLAND Engineer and Electrician 2 Sheepsear Grove
Benson Street Leeds do hereby declare the nature of this invention to be as
follows:-
According to my invention I build the frame of a reflector or diffuser of flexible
spokes, set radially in a disc or hub which may serve at the same time as a support
for a lamp, the said flexible spokes are curved over & may be connected to a circular
hoop, the framework thus assumes the form of an umbrella.
It is then covered with canvas or other suitable material which may be coated
with incombustible paint.

A New or Improved Reflector or Diffuser, principally applicable
for Photographic Purposes.
I, FREDERICK JOHN BORLAND, Engineer and Electrician, 2 Sheepscar Grove,
Benson Street, Leeds, 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 reference to a new or improved reflector or diffuser, principally
applicable for photographic purposes.
Fig. 1, is a plan of my invention.
Fig. 2, is a side elevation of Fig. 1.
Fig. 3, is a modification of my invention.
According to my invention I build the frame of the reflector or diffuser of flexible
spokes A, set radially in a disc or hub B which may serve at the same time as a
support for a lamp, the said flexible spokes A are curved over and may be connected
to a circular hoop C as shown in Figs. 1 and 2, or the ends may be free as shown
in Fig. 3, (the framework being in the form of an umbrella in both cases). It is
then covered with canvas or other suitable material which may be coated with
incombustible paint.
In the modification shown in Fig. 3, the flexible spokes A are set radially in a
disc or bub B which may serve as a support for the lamp.
Connected to the said disc or hub B are guide rods B upon which is a runner or
disc B2 receiving the ends of ribs D which are also pivotally joined to the spokes A.
A stop E is provided upon the guide rods B' for limiting the movement of the
runner or disc B2 thereon. The framework so formed is covered with canvas or
[Pd77

page_text: other suitable material, like Figs. 1 and 2 and may be coated with incombustible
paint.
To open the framework or reflector the runner or disc B2 is slid on the guide
rods B₁ until it comes in contact with the stop, the framework is then open like an
umbrella. To close the framework or reflector the runner or disc B2 is slid back-
wards upon the guide rods B₁, which closes the framework or reflector like an
umbrella.
In some cases when two or more arc lamps are used in series, one central guide
rod may be used instead of two, in this case a lamp will be on each side of the
guide rod.
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. A reflector or diffuser constructed with flexible spokes set radially in a disc or
hub, and joined to a circular hoop or ring, the frame so formed being covered with
canvas or other suitable material, such as shown and described with reference to
Figs. 1 and 2 of the drawings annexed.
2. A reflector or diffuser constructed with flexible spokes set radially in a disc or
hub, and ribs pivotally connected to the said spokes, and to a runner or disc capable
of being slid backwards and forwards to open and close the reflector or diffuser
which is covered with canvas or other suitable material substantially as shown and
described with reference to Fig. 3 of the drawings annexed.
