page_text: I, HENRY NORTON BUTLER Good, of Shrewton Lodge, Devizes, Gentleman do
hereby declare the nature of my invention to be as follows:-
=
This invention rolates more especially to photographic cameras in which pictures
are taken upon a film or strip of sensitized material, the position of which can be
adjusted as and when required, so that after each picture has been taken a fresh part
of the sensitized strip can be brought into the proper position to take a fresh picture,
and so on until the whole of the sensitized strip or film has been utilized.
In such cameras, as heretofore used, the strip or film of sensitized material is
wound upon a roller which is inserted into a separate slide and attached to the
camera, and is wound off the said roller as required and rewound (after the pictures
have been obtained upon the sensitized surface) upon another roller carried by the
removeable slide; and my present invention has for its objects novel methods of
construction by which the camera and lens, and the devices for carrying and moving
the film as required are united in one, instead of being separate, space is greatly
economized, and the entire apparatus is very cheap, light and portable, and effective.
It is more especially applicable to small cameras, in which a series of instantaneous
pictures can be taken at any desired moment.
My improved apparatus consists of a box or case of suitable size, preferably
rectangular, and of wood or other material. In front of this box is an opening
provided with an instantaneous or other shutter of any of the ordinary well-known
kinds, by which the opening can be opened or closed for the purpose of obtaining a
picture.
Behind the shutter I arrange in the box a transverse partition carrying a lens of
the required size and focus, and at the back of the partition I arrange two lateral
vertical partitions' the front edges of which join the front partition at each side of
the lens, whilst their back edges separate until they nearly reach the sides of the box
at a short distance from the back. In the angular spaces thus formed behind the
front partition I arrange the holding roller or spool and the receiving roller respec-
tively, the former having the sensitized strip or film wound upon it, the end of the

page_text: strip being led from it backwards then across the space between the back ends of the
lateral partitions, and again forward to the receiving roller, to which it is fastened
so that when the latter is turned round the strip is wound upon it and at the same
time unwound from the full roller or spool.
At or near the back edges of the lateral partitions I arrange vertical rollers or
guides, preferably of glass or of wood or other material covered with glass, round
which the film passes and is guided with very little friction or risk of abrasion.
Upon the interior surface of the top and bottom of the box or camera, just in front
of the sensitized strip or film as it passes across the back, I arrange two transverse
strips of wood or other material behind the edges of which the edges of the strip
pass, and against which they are pressed with sufficient force by a flat plate of
vulcanito or other suitable material which is pressed against the back of the strip by
a screw passing through the back of the box, or by other equivalent device.
At the back of the vulcanite plate a transverse metal spring is arranged one end
of which is fixed to one edge of the plate whilst its other end is pointed and is
sufficiently long to be bent forward and project slightly in front of the plate.
When the film or strip has been adjusted in the proper position to receive a picture
from the lens, the vulcanite plate is pressed forward by the screw so as to hold the
edges of the film firmly in position against the top and bottom strips, the point of the
screw first pressing forward the spring, the pointed end of which marks the paper
from the back sufficiently to indicate the position of the picture upon it when it is
ultimately removed from the rollers for the purpose of being cut up and developed
in the usual way. Small springs are arranged to press back the vulcanite plate from
contact with the back of the film when the pressure of the screw is withdrawn.
In one of the angular spaces first described between the front partition and the
lateral vertical partitions, I arrange a vertical roller against which the film or strip
presses, and which is made to revolve by such pressure when the rollers are made to
revolve and draw the strip forward.
The axle of this roller passes through the top or bottom of the box or camera and
is provided with a toothed pinion actuating an indicating device by which it can be
seen when the film has moved exactly sufficiently forward to present the proper surface
for a new picture, and also if desired to shew the number of exposures which have
been made and pictures taken.
The rollers which carry the sensitized strip or film are made readily removeable
so that they can be taken out and replaced as desired, their centres turning upon
screws in the top and bottom of the box or camera, which can be screwed up or
unscrewed as desired. The receiving roller is fitted at one end to a socket either
end of which can be turned round by a suitable key or handle for the purpose of
turning the roller and so causing the strip or film to pass behind the lens as already
described. I prefer to make the key removeable and with a solid ond, square or of
other suitable form, which fits into a corresponding hole in the end of the socket
which turns the receiving roller; and the same key may also fit into similar recesses
which carry the other centres for the rollers, and in this way no projecting part is
necessary outside the box or camera.
Either or both the rollers may be provided with ratchet wheels and palls, or their
equivalents, by which the rollers are prevented from turning in the wrong direction,
and spring or other brakes may be arranged so as to press upon the strip upon the
rollers, or upon brake wheels upon the roller sockets, and so keep the rollers from
too easily unwinding and thus allowing the strip to be imperfectly stretched.
A flat piece of transparent glass nay be arranged in front of the strip or film, the
latter being pressed against it by the vulcanite plate at the back.
By the improved methods of construction and arrangement which constitutes my
invention, great economy of space is effected, the rollers for holding the strip or film
being placed so as to occupy the smallest possible space. The flexible strip or film is
wound upon the roller so that as it passes in front of the vulcanite plate it has no
tendency to curve or buckle outward, but rather to remain flat in contact with the
plate, and so to ensure perfect pictures. Great advantage is thus obtained, since

page_text: when the strip or film is wound and used in the way described its surface is flatter
even if the vulcanite plate be altogether removed, than when wound in the manner
ordinarily hitherto used.
I preferably arrange the receiving roller so that when it is filled with the exposed
strip or film it can be very easily detached from its sockets, and an empty one sub-
stituted, so that it is not necessary to unwind the strip from the receiving roller.
Springs or hinged clips, or equivalent devices are attached to the rollers for the
purpose of fastening the ends of the strip or film, and the receiving and supplying
rollers are made alike and interchangeable so that they can be used for either purpose.

page_text: I, HENRY NORTON BUTLER GOOD, of Shrewton Lodge, Devizes, Gentleman, 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, and accompanying drawing, that is to say :-
My invention relates more especially to Photographic cameras in which pictures
are taken (generally instantaneously) upon a film or strip of sensitized material, the
position of which can be adjusted as and when required, so that after each picture
has been taken a fresh part of the sensitized strip can be brought into the proper
position to take a fresh picture, and so on until the whole of the sensitized strip or
film has been utilized.
In such cameras, as heretofore used, the strip or film of sensitized material is
wound upon a roller which is inserted into a separate slide or holder and attached to
the camera, and is unwound from the said rollor as required and rewound (after the
pictures have been obtained upon its sensitized surface) upon another roller carried
by the removeable slide; and my present invention has for its objects novel methods
of construction by which the camera and lens and the devices for carrying and
moving the film as required are united in one instead of being separate, the rollers
for holding the unused paper or other flexible sensitive film and the receiving rollers
for the same are so placed as to occupy the smallest possible space, so that space is
greatly economized and the entire apparatus is cheap, light, and portable, whilst the
paper or other film is wound in such a manner from one roller to the other that the
sensitive surface, which naturally curls inward, is kept flat by the glass or other
rollers round which it passes and is supported at its edges by guiding strips against
which it is pressed by a plate of vulcanite or other material which is forced forward
by a screw or cam at the back of the camera. When an exposure has been made the
pressure of this cam is roleased and the vulcanite plate is forced back by springs,
leaving free spaco for another fresh surface of the film to pass over the rollers when
wound off from the holding roller.
The cam or screw which presses the vulcanite plate against the back of the sensitive
paper may first press forward a spring at the back of the plate the end of which is
bent forward and sharpened to a point so that it makes a mark upon the paper
between the end of the vulcanite plate and the glass covered guiding roller thus
marking off in lengths the surfaces exposed.
A registering roller is also arranged over or round which the paper passes on its
way to the receiving roller. As the registering roller revolves it indicates upon an
indicating device outside the camera when the proper quantity of paper has been
wound off, and the number of exposures made.
My invention is more especially applicable to small cameras in which a series of
instantaneous pictures can be taken at any desired times.
.
In the accompanying drawings, which are in illustration of my invention, Figures 1

page_text: and 4 are perspective views, figure 2 is a horizontal section, and figure 3 a longitudinal
vertical section of the improved camera.
Figures 5, 6, 7, 8, and 9, are separate views shewing the receiving roller and its
connections. Figure 10 is a view of the back of the camera and the cam, and
figures 11, 12, and 13, are views of the ebonite plate and marking spring. Figure 14
is a separate view of the registering roller and its attachments.
The same letters of reference indicate the same parts in the several figures.
My improved apparatus consists of a box or case a of suitable size, preferably
rectangular, and of wood or other material. In front of this box is a opening b
provided with an instantaneous or other sbutter (not shewn in the drawing) of any of
the ordinary well known kinds, by which the spring can he opened and closed for the
purpose of obtaining a picture.
•
Behind the shutter I arrange in the box a transverse partition c carrying a lens of
the required size and focus, and at the back of the partition c I arrange two lateral
vertical partitions d d¹ the front edges of which join the front partition c at each side
of the lens, whilst their back edges separate until they nearly reach the sides of the
box at a short distance from the back. In the angular spaces thus formed behind the
front partition I arrange the holding roller or spool and the receiving roller el
respectively, the former having the sensitized strip or film i wound upon it, the end
of the strip being led from it backward then across the space between the back ends
of the lateral partitions d, d¹, and again forward to the receiving roller e¹ to which it
is fastened so that when the latter is turned round the strip is wound upon it and at
the same time unwound from the full roller or spool e.
At or near the back edges of the lateral partitions d¹¹ I arrange vertical rollers
or guides h h, preferably of glass or of wood or other material covered with glass,
round which the film i passes and is guided with very little friction or risk of
abrasion.
Upon the interior surface of the top and bottom of the box or camera a, just in
front of the sensitized strip or film i as it passes across the back, I arrange two
transverse strips k k (figure 3) of wood or other material behind the edges of which
the edges of the strip i pass and against which they are pressed with sufficient force
by a flat plate of ebonite or other suitable material which is pressed against the back
of the strip by a screw, wedge, or cam m passing through the hinged back of the
box (as shewn in figures 2, 3, and 10).
At the back of the ebonite plate la transverse metal spring n is arranged one end
of which is fixed to one edge of the plate whilst its other end at n' is sufficiently
long to be bent forward and project slightly in front of the plate its end being
provided with one or more points (figures 11, 12, and 13).
When the film or strip i has been adjusted in the proper position to receive a picture
from the lens, the ebonite plate is pressed forward by the screw or cam m so as to
hold the edges of the film firmly in position against the top and bottom strips k, k,
the screw or cam m first pressing forward the spring n, the pointed end of which
at n marks the paper i from the back sufficiently to indicate the position of the
picture upon it when it is ultimately removed from the rollers for the purpose of being
cut up and developed in the usual way. Small springs o are arranged to press back
the ebonite plate from contact with the back of the film i when the pressure of the
screw or cam m is withdrawn.
In one of the angular spaces first described between the front partition c and the
lateral vertical partitions & d', I arrange a vertical roller p against which the film or
strip i presses, and which is made to revolve by such pressure when the rollers e el
are made to revolve and draw the strip i forward.
The axle of this roller p may be provided with a toothed pinion actuating an
indicating devicer on the outside of the camera by which it can be seen when the film
has moved exactly sufficiently forward to present the proper surface for a new picture,
and also if desired to show the number of exposures which have been made and of
pictures taken.
The rollers e e¹ which carry the sensitized strip or film i are made readily removeable

page_text: so that they can be taken out and replaced as desired, their centres turning upon
screws sss in the top and bottom of the box or camera, which can be screwed up or
unscrewed as desired.
The receiving roller e' is fitted at one end to a socket t (figures 7 and 8) the outer
end of which can be turned round by a suitable key or handle for the purpose of
turning the roller and so causing the strip or film i to pass behind the lens as
already described. I prefer to make the key removeable and with a solid end, square
or of other suitable form, which fits into a corresponding hole in the end of the
socket t which turns the receiving roller e; and the same key may also fit into
similar recesses which carry the other centress for the rollers, and in this way no
projecting part is necessary outside the box or camera.
Either or both the rollers e e' may be provided with ratchet wheels and palls, or
their equivalents, by which the rollers are prevented from turning in the wrong
direction, and spring or other brakes (such as shewn at figures 2 and 4) may be
arranged so as to press upon the strip upon the rollers, or upon brake wheels
upon the roller sockets, and so keep the rollers from too easily unwinding and thus
allowing the strip to be imperfectly stretched.
The axle of the registering roller p may be carried in noveable bearings at one
or both ends as shewn in figure 14, the bearing w in which the axle revolves, being
capable of moving backward and forward in a guide and then being constantly
pressed inward by lever and spring y.
In this way the film is kept constantly stretched by the elastic pressure of the
roller p against it. Similar moveable bearings may also be used for the other rollers
if desired.
By the improved methods of construction and arrangement which constitute my
invention, great economy of space is effected, the rollers for holding the strip or film
being placed so as to occupy the smallest possible space in the angles between the
rtition c and those d and d.
с
The flexible strip or film is wound upon the rollers so that as it passes in front of
.the ebonite plate it has no tendency to curve or buckle outward, but rather to remain
flat in contact with the plate, and so to ensure perfect pictures. Great advantage is
thus obtained, since when the strip or film is wound and used in the way described
its surfaco is flatter even if the ebonite plate be altogether removed, than when wound
in the manner ordinarily hitherto used.
Stops or diaphragms may be introduced through an opening at A (figures 1 and 4) |
and a small finding lens for determining the picture may be placed at B.
The rollers ee can bo very casily detached from their sockets, and others
substituted for them so that it is not necessary to unwind the strip from the receiving
roller.
Spring or hinged clips, or equivalent devices such as hollow flexible metal wedges
(as shewn in figures 2 and 5) are attached to the rollers for the purpose of fastening
the ends of the strip or film, and the receiving and supplying rollers are made alike
and interchangeable so that it can be used for either purpose.
The trouble and the risk of damaging the sensitive surface of the paper (by
being obliged to unwind all the exposed part off the receiving roller when the
holding roller or spool is empty) are avoided by providing the inexpensive rollers
and metal clips of the same size as the spools upon which the paper is supplied by the
makers. These rollers are capable of being detached from the sockets that hold their
ends, as easily as spools, and the sockets of each (receiving roller and spool) may
bo of the same shape, so that the ordinary old spools, with the addition of a
small piece of metal secured to their ends with small screws, may be used as receiving
rollers.
The entire camera may be covered with leather, paper, or other material, so as not
to be too conspicuous or readily noticeable.
The sides of the camera are closed, preferably by plates of ebonite, wood, or other
suitable material, sliding in grooves, and fitting so closely as to prevent the admission
.of: light.
