I, HENRY PARK, of 1 Orchard Buildings, Kingsland Road, in the County of
Middlesex, Photographic Apparatus Manufacturer, do hereby declare the nature of
my said invention to be as follows:-
:-
The object of my invention is to effect improvements in the construction of folding
photographic cameras, whereby they are rendered compact and portable, and improved
facilities for manipulation are afforded.
I form the base board in two parts, the lower half of the board being made solid,
and the upper (sliding) half being a rectangular frame, provided with rabbets and
racks, as usual. The upper part of the base board is made to slide forward upon the
lower base board.
The lower base board is fitted on each side with a metallic groove or slot. In each
of these slots I fit a slide bar, which carries the lower centre or pivot of the radial
bar or link, and also a vertical bracket and a set screw. The set screw is used to fix
the position of the slide bar in the slot, and the bracket is fitted with a screw which
forms one of the pivots for the back board.
The focussing pinion is fitted to the lower base board, and the front plate is fitted
to the upper base board, to which it is fixed in any required position by set screws
and nuts.
The bellows body is made parallel, and is attached to the front and back plates in
the usual manner.

page_text: The main features of novelty in this invention are, the outside metallic grooves in
the base board; the slides which work therein; the brackets attached thereto
carrying the working centres of the back board this back board having double swing
motion, which allows the back part of the camera to be put in any position on the
base board, as required, when wide-angled lenses are used, readily and without
detachment; also the adjusting links; also the means of folding the camera (no
hinges being used), and the protection afforded to the focussing plate by the solidity
of the lower base board, when packed.
The camera is fitted with all the usual appliances for manipulating the same.

Improvements in the Construction of Photographic Cameras.
I, HENRY PARK, of 1 Orchard Buildings, Kingsland Road in the County of
Middlesex, Photographic Apparatus Manufacturer, do hereby declare the nature of
my said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to effect improvements in the construction of folding
photographic cameras, whereby they are rendered compact and portable, and improved
facilities for manipulation are afforded.
I form the base board in two parts the lower half of the board being made solid,
and the upper (sliding) half being a rectangular frame, provided with rabbets and
racks, as usual. The upper part of the base board is made to slide forward upon the
lower base board.
The lower base board is fitted on each side with a metallic groove or slot. In
each of these slots I fit a slide bar which carries the lower centre or pivot of the
radial bar or link, and also a vertical bracket and a set screw. The set screw is used
to fix the position of the slide bar in the slot, and the bracket is fitted with a screw
which forms one of the pivots for the back board.
The focussing pinion is fitted to the lower base board, and the front plate is fitted
to the upper base board, to which it is fixed in any required position by set screws
and nuts.
The bellows body is made parallel and is attached to the front and back plates in
the usual manner.
The main feature of novelty in this invention are, the outside metallic grooves in
the base board; the slides which work therein; the brackets attached thereto carrying
the working centres of the back board this back board having double swing motion
which allows the back part of the camera to be put in any position on the base board,
as required, when wide angled lenses are used readilly and without detachment; also
the adjusting links; also the means of folding the camera (no hinges being used)
and the protection afforded to the focussing plate by the solidity of the lower base
board, when packed.
The camera is fitted with all the usual appliances for manipulating the same.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a perspective view of my invention with the camera nearly closed,
shewing that the base board folds up and does not project, as in ordinary cameras;
and Fig. 2 shews the camera extended. a is the back board, b is the groove in the
base board, c shews the position of one of the slides attached to the bracket d and
e e are the set screws for the brackets and slides.

page_text: Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. The manufacture and use of photographic cameras, having the base board
formed in two parts, so as to fold together telescopically, substantially as herein before
described and shewn on the drawings.
2. In the construction of photographic cameras as aforesaid the adaptation of metallic
grooves b, for accommodating the slides to the brackets d, substantially as herein
before described and shewn on the drawings.
3. In the construction of photographic cameras as aforesaid, the adaptation of
slides c, to support and regulate the brackets d, substantially as herein before described
and shewn on the drawings.
4. In the construction of photographic cameras as aforesaid, the adaptation of
brackets d, substantially as and for the purposes herein before described and shewn
on the drawings.
5. The general construction, combination, and arrangement of the several and
respective parts, together constituting my improvements in the construction of
photographic cameras, substantially as hereinbefore described and shewn on the
drawings.
