Improved Pocket Photographic Apparatus.
I, NEWNHAM BROWNE, of 73, Cheapside, in the City of London, Chartered
Patent Agent, 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 has for its object an improvement of those small photographic
apparatus which can be so folded up as to be able to slip into a coat
pocket. The object of this improvement is to simplify the manipulation of the
apparatus when it is being unfolded, or to make such unfolding automatic.
When folded up for transport such an apparatus has the form of a little flat
box the base board forming the lid of the box.
When the apparatus is to be set up into the condition in which it can be used
for making an exposure, the base-board (which till then formed the lid) is folded
back, brought into position for use, and fixed in that relative position by a
suitable device. The front which is inside the casing, together wth the bellows
arrangement has next to be removed respectively pulled out and properly fixed or
adjusted on the base board.
All this requires a number of manipulations a part of which are obviated by the
present improvement.
This is illustrated in the accompanying drawings showing a pocket camera
Fig. 1, being an elevation, Fig. 2, vertical section, Fig. 3, horizontal section of
same when folded up, and Fig. 4, side elevation, Fig. 5, vertical section, Fig. 6,
horizontal section when unfolded.
In the drawings g is the back or casing of the apparatus, 7 the base-board, o the
front, o' the lens, 6 the bellows, the focussing screen, which for exposure can be
replaced by a dark slide and plate inserted into the casing g.
The improvement in the apparatus consists in a device which has for its
object automatically to bring the front o and bellows b into proper position for use
when the base board is in that relative position.
This device consists in the following.
At either side of the apparatus a knee lever k is provided and jointed to the
front o and the casing g respectively. In the drawings these knee levers are shown
arranged within the bellows b so as to economise space but they may with equal
efficiency be placed outside.
In the knee joint of each lever ka spring m is provided tending to bring the
lever into the straightened position shown in Figs. 5 and 6. In passing into this
position the knee levers force the front and the bellows b into the operative
position shown in Figs. 4 to 6.

page_text: The points where the lever k act are placed near the base board / both on
the casing or back g and on the front o so as to avoid jamming of the front o
when passing along the guide provided therefor on the base board l.
Having now particularly described and ascertained the nature of my said
invention, as communicated to me by my foreign correspondent, I declare that
what I claim is:
1
An improved folding pocket apparatus for photography characterized by knee
leversjointed on the one hand to the back or casing g on the other to the front o
said levers being straightened by spring m provided at the knee joints of such
levers, the levers bringing the front o and bellows & into proper position for use
relatively to the back g when the base board assumes its position for use.
Dated the 10th day of October 1897.
