An Improved Roll or Spool upon which Flexible Photographic
Films are Wound.
JAMES BOOKER BLAKEMORE WELLINGTON Manufacturer of Photographic
Papers, The Elms, Boreham Wood Elstree, Herts, do hereby declare the nature
of this invention to be as follows:-
This invention has for its purpose to provide a roll or band of flexible photo-
graphic film which is so adapted that it can be used in connection with the wooden
spools upon which photographic films of this character have hitherto been
supplied to the trade.
The wooden spools upon which flexible film of paper, celluloid or other material,
has been hitherto wound have been provided with a longitudinal groove by means
of which the end of the film has been attached through the indentation of a clamping
strip of tin, a method well known to those skilled in the art.
It is my purpose to provide a roll of flexible film which may be utilized in
existing photographic apparatus by slipping this roll over the wooden spool, which
it is made to fit. At the same time my improved roll is prevented from turning
upon the wooden spool by means of an inwardly projecting rib or strip which
corresponds or fits the beforementioned longitudinal groove in the wooden spool.
This purpose I attain by rolling one or more thicknesses of the film itself so as to
form a shell or tube which shall fit over the said wooden spool and glueing these
thicknesses together by means of suitable and adhesive material, so that they
cannot become unrolled during manipulation in the roll holder or camera.
The beforementioned projecting rib which is to fit in the grove of the wooden
spool I provide by causing an indentation of a fold of the film which forms the
shell to be glued up in it, or by attaching to the end of the film a narrow strip of
bent tin or a strip of wood or other suitable substance which shall severally fit the
before mentioned groove.
Rolls of sensitized photographic film prepared in accordance with my invention
may thus be directly employed in connection with existing photographic apparatus
by being slipped over the empty wooden supply rolls hitherto in use, when thus
attached they will be adapted to be used in conjunction with any of the well
known forms of apparatus intended for the exposure of long strips of sensitive
photographic film, inasmuch they will turn together with the existing wooden
rolls.
It is well understood that sensitized photographic films such as which forms the
subject of my invention will be supplied to the operator in suitable light tight
packets.

Films are Wound.
I, JAMES BOOKER BLAKEMORE WELLINGTON,. Manufacturer of Photographic
Papers, of The Elms, Boreham Wood, Elstree, Herts, 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 to provide a roll or band of flexible photo-
graphic film which is adapted to be used in connection with the wooden spools
upon which photographic films of this character have hitherto, been supplied to, the
trade.
I will describe my invention with reference to the accompanying drawings.
Fig. 1 is a section of a wooden spool a upon which flexible film of paper,
celluloid or other material has been bitherto wound, these spools have been
provided with a longitudinal groove a' within which the end of the film has been
clamped by means of a strip of tin which indented the film into said groove for
the purpose of compelling the spool and film to turn together, a method well known
to those skilled in the art.
According to my invention I provide roll 6 such as that shown at Fig. 2 of
flexible film which may be utilized in existing photographic apparatus by slipping
this roll over the aforesaid wooden spool a which it is made to fit as represented
at Fig. 3. At the same time my improved roll is prevented from turning upon the
wooden spool by means of an inwardly projecting rib or strip 6 which
corresponds with or fits the before mentioned longitudinal groove a¹ in the wooden
spool a.
a
I attain this object by rolling one or more thicknesses of the film itself upon a
wooden spool a or upon a mandrel of like form so as to form a shell or tube b
which shall fit over the said wooden spool and I cement these thicknesses together
by means of suitable adhesive material, so that they cannot become unrolled during
manipulation in the roll holder or camera.
The before mentioned inwardly projecting rib or strip & which is to fit in the
groove a¹ of the wooden spool a I provide by indenting a part of the first fold or
coil of the film which forms the shell or roll b and applying a suitable cement to
the outside of said fold or coil extending on each side of said indent, then by
rolling another thickness of the film over such cemented part the said coils are
secured together and the rib or strip b' is maintained in its correct form.
Or I may attach to the end of the film a narrow strip of bent tin or a
wood or other suitable substance which shall fit the before mentioned groove a¹.
strip of
Rolls of sensitized photographic film prepared in accordance with my invention
may thus be directly employed in connection with existing photographic apparatus
by being slipped over the empty wooden supply rolls or spools hitherto in use;
when thus attached they will be adapted to be used in conjunction with any of the
well known forms of apparatus intended for the exposure of long strips of sensitized
photographic film inasmuch as they will turn together with the said wooden rolls
or spools.
It is well understood that sensitized photographic films of the character herein
referred to will be supplied to. the operator in suitable light tight packets.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A hollow roll or spool upon which flexible photographic film is wound formed with

page_text: an internally projecting rib or strip and of the same material as the photographic
film substantially as herein shown and described and for the purpose stated.
