Improvements in and relating to Film Packages for Photographic
Cameras.
I, BENJAMIN JOSEPH EDWARDS, of The Grove, Hackney, in the County of
Middlesex, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to film packages for photographic cameras and roller slides
and to means for adapting my improved packages to be used in ordinary roll-
holders or cameras.
One object of my invention is to provide a light-tight film package for roller
slides which may be used in existing cameras or roll-holders and changed in
daylight, and which packages will take the full width of film for which such
cameras or roll holders are constructed.
Another object of my invention is to make the film packages interchangeable so
that in existing cameras the empty roller with its sheath can be changed and used
as a receiving roller.
According to one part of my invention I provide a film-package so constructed
that the extreme length of the said package exceeds but a very trifling amount the
width of the film to be contained therein, and so mount the roller in a sheath that
no light shall be admitted to the interior of the package. To this end I construct
my improved packages with special end pieces or caps of very thin material which
also serve as efficient bearings or support for the roller and also allow of the roller
being rotated from the outside of the case.
My improved package comprises a roller on which the film is wound, and a sheath
or covering for enclosing the film and protecting the said film from light. The
sheath or covering is made of cardboard or other suitable material shaped or folded
so as to form a hollow tube having a slit or opening throughout its entire length
through which slit the film is drawn. This slit is made light tight by binding its
edges with strips of velvet or the like. I provide the folded sheath or covering
with end pieces constructed of very thin material preferably of thin sheet metal
which can be very cheaply produced of the required shape by stamping. The
bearings I form as follows, I provide an annular recess in each end of the roller.
and I stamp or otherwise form a central circular opening in each cap or end piece
and turn inward the edges of the said openings, so as to form flanges which fit into
the said annular recesses in the roller and serve as bearings therefor. The outer
edges or rims of the said caps are turned or flanged inward to fit tightly over the
ends of the sheath or covering. By this construction I not only utilize the full
length of the roller for the film but I avoid in a simple manner all risk of the light
finding its way into the covering and so spoiling the film. 1 construct one or both
ends of the roller to form a clutch to engage with the fittings of the camera or roll
holder thereby enabling the roller to be turned from the outside of the case by the
winding key.
In order to enable my improved light-tight film packages to be used in roll-
holders or cameras as usually constructed which are not adapted for being charged
or refilled in daylight and in which the fittings of the discharging and receiving
rollers are not of a uniform pattern I provide a device which I term an "adapter."
This device is adaped to fit without turning 'in the end of my improved spool or
roller and is shaped at its outer end to fit on the usual key or clutch of the receiving
roller of the ordinary roll-holder or camera. This "adapter can be arranged to
fit or connect with any kind of clutch, and is removable or interchangeable. By
means of this device my film packages can be used in existing cameras and the

page_text: empty spool or roller with its light-tight case may be used as a receiving roller, the
ordinary receiving roller being dispensed with. When the receiving roller is full,
it can be removed and an empty spool with its light-tight case put in its place, the
adapter" being changed from the full roller to the empty one.

COMPLETE SPECIFICATION.
Improvements in and relating to Film Packages for Photographic
Cameras.
I, BENJAMIN JOSEPH EDWARDS, of The Grove, Hackney in the County of
Middlesex, Manufacturer, 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:-
My invention relates to film packages for photographic cameras and roller-slides,
and to means for adapting my improved packages to be used in ordinary roll-
holders or cameras.
One object of my invention is to provide a light-tight film-case for roller slides
which may be used in existing cameras, or roll-holders, and changed in daylight,
and which case will take the full width of film for which such cameras or roll-
holders are constructed.
Another object of my invention is to make the film packages interchangeable so
that in existing cameras the empty roller with its sheath can be changed and used
as a receiving roller.
According to one part of my invention 1 provide a film-case so constructed that
the extreme length of the said case exceeds but a very trifling amount the width
of the film to be contained therein, and so mount the roller in the sheath that no
light shall be admitted to the interior of said sheath. To this end I construct my
improved case with special end pieces or caps of very thin material which serve as
efficient bearings or supports for the roller and which also allow of the roller being
rotated from the outside of the case.
In order that my said invention may be clearly understood, I will now proceed
to describe the same with reference to the accompanying drawings, in which
Figure 1 is a longitudinal central section of an improved film-case of octagonal
form, constructed according to my invention.
Figure 2 is a transverse section of the same showing the film contained
therein.
'
Figure 3 is a section of the end cap or piece detached.
Figure 4 is an end view of the roller.
Figure 5 is a perspective view of a portion of the case.
Figure 5 is a similar view of a square case.
Figure 6 is a perspective view of a detail hereinafter particularly described.
My improved package comprises a roller A on which the film is wound and a
sheath or covering B for enclosing the film and protecting the said film from light.
The sheath or covering is made of cardboard or other suitable material shaped or
folded so as to form a tube, of square, octagonal or other convenient shape, having
a slit or opening B' throughout its entire length, through which slit the film is
drawn. This slit is made light-tight by binding its edges with strips B² of velvet
or the like. I provide the folded sheath or covering with end pieces C constructed
of very thin material, preferably of thin sheet metal, which can be very cheaply
produced of the required shape for example by stamping. I form the bearings
for the roller A as follows; I provide an annular recess A¹ in each end of the
roller and I stamp or otherwise form a central circular opening C¹ in each cap or

page_text: end piece C and turn inward the edge C' of the said opening so as to fit into the
said annular recess A¹ in the roller and serve as a bearing therefor. The outer
edges or rims C³ of the said caps are turned or flanged inward to fit tightly over
the ends of the sheath or covering, and preferably certain parts thereof are
indented as at C to enter and clinch the said sheath or covering to assist in
retaining the caps in position. As additional means, for the same purpose I can
employ when desirable a strip of paper gummed or cemented to the said caps and
to the adjacent portion of the casing. Or the said ends instead of being made of
metal, can be made of thin cardboard or of leather-board, in which case they are
secured in place by glue.
By this construction of film-package I not only utilize the full length of the
roller for the film but I avoid in a simple manner all risk of the light finding its
way into the covering B and so spoiling the film.
I construct one or both ends of the roller to engage with the fittings of the
camera or roll-holder, thereby enabling the roller to be turned from the outside of
the case by the clutch or winding key.
The
In order to enable my improved light-tight film packages to be used in roll-
holders or cameras as usually constructed which are not adapted for being charged
or refilled in daylight, and in which the fittings of the discharging and receiving
rollers are not of a uniform pattern, I provide a device which I term an "adapter.'
This device is illustrated in Figure 6. It consists of a plug D having a pin D
passing through the same near one end. The end of the roller is provided with a
central recess A³ to receive the end of the plug D and with cross grooves A' in
one of which the pin D' will lie when the plug is placed in position therein.
said plug is thus adapted to fit without turning in the end of my improved spool or
roller. It is formed at its outer end with a cross cut or groove D' or a clutch
adapted to fit on the usual clutch of the receiving roller of an ordinary roll-holder
or camera. This "
'adapter" can be arranged to fit or connect with any kind of
clutch and is removable or interchangeable. By means of this device my film-
packages can be used in existing cameras, and the empty spool or roller with its
light-tight case may be used as a receiving roller, the ordinary receiving roller
being dispensed with. When the receiving roller is full, it can be removed and an
empty spool with its light-tight case put in its place, the "adapter" being changed
from the full roller to the empty one.
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. A film-package or case having a roller provided with an annular groove in
one or both ends, to form a bearing surface or bearing surfaces on which the
roller can turn, for the purpose specified.
2. A film-package or case provided with caps or end pieces having annular
interval projections to form bearings for the roller, substantially as described, for
the purpose specified.
3. In a film-package or case, a roller having an annular groove formed in one or
both ends forming bearing surfaces for the roller, in combination with end pieces
having central openings the edges of which are turned inward and are adapted to
fit in the said annular grooves, for the purpose specified.
4. The combination with the light-tight sheath or covering and the roller, of
thin sheet metal or other suitable end pieces having rims adapted to fit tightly on
the sheath, and central circular openings the edges of which turn inward and are
adapted to enter annular grooves in the ends of the roller and form bearings for
the roller, with or without other fastenings to hold the ends in place, substantially
as described for the purpose specified.
5. A light-tight film-package or case provided with internal annular bearings
for the roller which enable the roller to be rotated from outside the case, substau-
tially as described.

page_text: 6. A light-tight film-package or case constructed substantially as described
with reference to the drawings.
7. In a roller slide a movable "adapter" which enables the rollers to be inter-
changed, substantially as described.
8. The combination of the light-tight sheath, its end pieces, the roller, and a
-sensitive film wrapped on the roller, substantially as described.
