An Improved Finder Shade for Cameras.
EDMUND GEORGE PLATT, Birkbeck Road, Ridley Road, Dalston, London, N.E.,
Brassfinisher, 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 refers to finder shades for cameras and consists of a four-sided
callapsible shade made of light metal hinged flaps which can be quickly folded
flat or opened out to form a rectangular aperture.
Each of the four sides or flaps of the shade folds inwardly into the aperture,
one folding down first and the others following in regular sequence.
When opening the shade if the top side is lifted the other three follow in order
and rise automatically. This is effected by means of small coiled springs placed
at their hinged inner sides. Three of these springs are made to throw the flaps
up or outwards. One of them which operates the outside or cover flap draws
inwards. Thus when the flaps are closed this cover flap keeps the others securely
in position.
A small frame connects the four flaps together and enables them to be fixed
to the camera.
I will now describe the invention with reference to the accompanying drawings
in which:-
Fig. 1 shews a top plan view of the finder shade closed.
Fig. 2 shews a bottom plan view of same.
Fig. 3 shews a perspective elevation of the finder shade open.
Fig. 4 shews one of the hinged flaps detached.

page_text: a is the frame, provided with two ears, a¹, in which are formed holes, for
convenient attachment to the camera frame.
bcd and e are hinged flaps, each of the flaps has a turned over or tubular edge,
which projects on each side. A wire which is rivetted in the frame a passes
through this tube, a portion of which near its centre is cut away at g to receive
a small coiled spring f, which is placed around the centre wire h and extends
across the cut away portion of the tube.
The flaps c d and e are fitted with springs which have a tendency to open the
said flaps, whilst the spring on the flap b has a tendency to keep it closed. This
flap is prolonged and also bent at its upper end to fit over the top of frame a
thus forming a thumb piece by which the top flap can be conveniently raised.
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 four-sided collapsible finder shade for cameras consisting of the frame a,
flaps b c d and e, springs f and wire h, as herein described and set forth.
