We EDWIN MARTIN KNIGHT of 148 Cheapside London, Machinery Agent, and
GEORGE HENRY KNIGHT of 148 Cheapside London Commercial Traveller, do
hereby declare the nature of our said invention for "IMPROVEMENTS IN APPLIANCES
TO BE EMPLOYED IN THE MANUFACTURE OF FOLDING OR POCKET CAMERAS," to be
as follows: -
This invention relates to improved appliances to be employed in the manufacture
of pocket or folding cameras for which latter invention application for patent was
made by us. on 29th day of June 1886 No. 8654; the object being to provide
appliances for creasing or marking, folding and blocking the paper or other
material from which the bellows, camera lens, and sensitive plate holding appliance
is constructed, and such apparatus comprises a board to which L or angled metal
plates are secured to the board in V and paralell lines; the paper is cut to required
width and length according to the size of the camera, its onds are received on
guage pins which hold it in position on the L plates where it is rubbed so as to
indent and crease it.
Its opposite side is next on a similar board having a suitable arrangement of the
L plates when it is again rubbed and creased.
Next the paper is placed upon a board having guage pieces which receive a
block, one surface resting on the paper, the ends of the latter are now folded over
the block and gummed; when dry the block is withdrawn leaving a rectangular
shell of creased paper which through the creases referred to is folded and forms
a bellows as also the receptacles for the lens plate at one end and the sensitive
plate at the opposite end of the said shell.

We EDWIN MARTIN KNIGHT, of 148 Cheapside London, Machinery Agent, and
GEORGE HENRY KNIGHT of 148 Cheapside, London Commercial Traveller, do
hereby declare the nature of our invention for IMPROVEMENTS IN APPLIANCES TO
BE EMPLOYED IN THE MANUFACTURE OF FOLDING OR POCKET CAMERAS," 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 improved appliances to be employed in the manufacture
of pocket or folding cameras, for which latter invention, application for patent was
made by us on 29th day of June 1886 No. 8654: the object being to provide
appliances for creasing or marking, folding and blocking the paper or other
material from which the bellows, camera lens, and sensitive plate holding appliance
is constructed and such apparatus comprises a board to which L or angled metal
plates are secured to the board in V and parallell lines; the paper is cut to required
width, and length according to the size of the camera, its ends are received on
guage pins which hold it in position on the L plates where it is rubbed so as to
indent and crease it.
Its opposite side is next placed on a similar board having a suitable arrangment
of the plates when it is again rubbed, and creased.
Next the paper is placed upon a board having guage pieces which receive a
block, one surface resting on the paper. The ends of the latter are now folded
over the block, and gummed; when dry the block is withdrawn leaving a rect-
angular shell of creased paper, which through the creases referred to, is folded, and
forms a bellows as also the receptacles for the lens plate at one end, and the
sensitive plate at the opposite end of the said shell.
Such being the nature and object of our invention the following is a complete
description of same reference being had to the accompanying drawings forming
a part of this specification, in which :-
Fig. 1. is a plan view of the board A. and L plates on which the paper or other
material is first prossed.
Fig. 2. is a plan view of the board B and I plates on which the paper or other
material is pressed after being on the board represented by Fig. 1.
Fig. 3. is a plan view of board C shewing block in position.
Fig. 4. is a side view, and Fig. 5 an end view of block.
The apparatus is to be used as follows:-
Having cut the paper to about the length and width of the board A place the
paper upon the guage, and holding pins 1. 2. next place a piece of cloth over the
paper, and by pressure and rubbing by the hand cause the edges of the L plates 3.
to indent, and form croases, or crease lines on the surface of the paper. Remove
the paper, and place its reverse side upon the board B the guage pins 4. 5. entering
the holes made by the pins 1. 2. of the board A, and again press and rub the paper
upon the metal edges 6 which will in similar manner crease, and line its surface.
Next remove the paper to the board C and place it in such position that the creases

page_text: made by edges 61 6¹ will be directly under the outer edges of the hollow block 7.
when the latter has been passed through its guide block 8. 8. Now fold the outer
ends of the paper over the block, and they will overlap each other, next by gum
or paste secure one upon the other. When dry fold the end creases upon the end
of the block and when the block is withdrawn there will thus be found a secure
face for a card of paste board, wood, or other like light material, in the centre of
which is a pin hole lens the other piece may be secured to the folded ends by a
little gum or paste, the shell is then pressed and folded at the creases along its
length whereon the shell will collapse bellows like, the outer ends fold and form
a receptacle for the sensitive plate, same as for the card board carrying the lens at
the other end of the camera the folded ends are pasted or gummed down on the
back of the sensitive plate, and the whole is complete.
Having now particularly described and ascertained the nature and object of our
said invention, and in what manner the same is to be performed we declare that
what we claim is :-
The folding boards A. B. C. having the Land | creasing edges together with the
block 7. all in combination, constructed as, and for purpose herein fully described
and as illustrated by annexed drawings.
