I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of
Patent Agents, do hereby declare the nature of this Invention (a communication
to, me from abroad by E and H. T Anthony and Company, a Corporation incor-
porated under the laws of the State of New York, doing business in the City,
County and State of New York, United States of America Manufacturers) to be as
follows.
This Invention consists of a light tight box having a light tight passage way for
the movement of the paper sheet into or out of the box and which is light tight
both when the sensitized sheet is wholly within the box and when it is being
moved in or out of the same, and the invention comprises various constructions
and combinations of parts including a roller within the box as above for carrying
the sensitized sheet and which is made capable of being operated from the exterior
of the box for drawing in, out, and storing the paper or sheet. .The invention also
includes various other constructions and combinations of parts whereby the efficiency
of the case is very perfectly secured as hereinafter described. The invention is
applicable to carrying, preserving, and supplying, as required, all kinds of flexible
sensitized tissue or paper whether sensitized on one or both sides and whether
used for making negatives or for photographic printing.
The case is mainly made up of an oblong box or body part, and correspondingly
shaped lid part hinged to the box part by one of its long sides and passing, at its
ends, when being closed within plates secured to the ends of the box part. The
box or case whether thus or otherwise constructed, is to be provided with a longi-
tudinal passage way for the movement of the paper to and from the interior of the
box and this passage-way is made light-tight in any suitable manner. One method
of making said passage-way light-tight and the one which is preferred is as follows:
A longitudinal opening is provided in the front of the box along one edge of which
is fitted a packing strip or wiper of soft flexible material, such as cloth, which

page_text: forms one lip of said passage-way. Said wiper, as for instance when the longi-
tudinal opening is formed between the free edge of the lid and the body or box
part of the case may be secured in any suitable manner to the interior of the lid.
Said wiper closes against a small longitudinal roller which is journalled in its ends
in the end plates of the box, and constitutes the other lip of the passage way and
this roller together with the wiper are so adjusted in respect to each other that
there is a passage-way between them for the paper, which passage-way is light-
tight, both when the paper is introduced between the roller and wiper, and also
when the paper is wholly withdrawn from between said parts. To prevent the
access of light to interior of the box at the opposite side of the roller there is
arranged another longitudinal wiper of suitable soft material to bear against that
side of the roller, this second wiper being attached to the interior of the box part
of the case.
The roller serves as a guide for the tissue or paper as it is drawn over it to supply
or measure off any desired amount of paper which is then torn off immediately in
front of or close up to the guide roller, thus leaving the remainder of the paper
under the close and light-tight cover of the case.
Furthermore, the two wipers are arranged so that the one wiper acts on the
friction or guide roller throughout its length to keep it clean or free from dust and
the other wiper acts on the tissue or paper itself for a similar purpose, thereby
preventing injury to the sensitized surface of the paper by dust collecting on it.
This is in addition to the hereinbefore described other and main functions of said
wipers, namely, of excluding light from the interior of the case and which if
admitted would destroy the usefulness of the tissue or paper for photographic
purposes.
•
Within the box or body part is a longitudinal roller which carries or has wound
upon it the flexible sensitized sheet or tissue, the inner or one end of the roll or
sheet being entered down within a longitudinal recess in the roller and engaging
with pins or pointed teeth therein, whereby a firm hold is obtained for the paper
without exposing it to being punctured otherwise than at its end and through a
single thickness, thus preventing the marring of the sheet or roll of sensitive paper.
This roller, which may be of wood or other suitable material, is protected at its
ends by ferrules, which are constructed with outer tubular central necks or
externally circular sockets, whereby said ferrules are also made to form journals
for the roller and, by suitably shaping the interior of said sockets, provision is
made for introducing a key to engage with the roller for the purpose of rotating
it to roll or take up the paper either when first charging the case or in the event
of more paper being drawn out than is necessary at any one time. By arranging
these ferrule-journals at both ends of the roller carrying the paper, opportunity is
afforded for turning said roller by its key from either end of the case. Said ferrule-
journals have their bearings in the and plates of the box which thus form journal-
boxes as well as end covers to the case constructed to exclude light from entering
at the end joints of the case.
To prevent the too free turning of the roller or in other words to throw a
resistance upon it by friction which will retard its run and so facilitate the drawing
out of the sensitive paper from the case in measured or desired quantities, cupped
spring washers are introduced at the ends of said roller between it and the ends of
the case thereby producing an endwise pressure against the roller.
To more effectually exclude the light from the interior of the case when closed,
the lid has not only a close fit at its ends under cover of the end plates but a
tongue and groove fit with the box-part of the case along or in line with the hinges,
and the case is held close shut and friction thrown upon the wipers, guide roller,
and tissue, passing over said roller, by a spring strap or fastening pivoted to the
ends of the body part of the case and arranged to pass longitudinally over the lid
part thereof; or spring straps or fastenings pivoted to the body part at front and
back close to the ends of the case and bearing down on the lid transversely may be

page_text: used, said straps or fastenings being thrown off at the back or ends of the box as
the case may be, so that the box may readily be opened when required to introduce
a fresh sheet or roll of tissue or as other circumstances may render necessary.
Other suitable fastenings may be used.
The case as thus described for storing photographic sensitive paper may be
carried in the pocket or elsewhere without risk of exposing said paper to light or
dust, and the paper may be torn off for use in lengths of any desired size without
affecting or exposing the remainder, and the case will be found much more
convenient in this and other respects than a portfolio carrying between its leaves
detached lengths or pieces of photographic sensitive paper.

page_text: I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
63, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this Invention (a communication to me
from abroad by E. and H. T. Anthony and Company (Manufacturers) a Corporation
incorporated under the Laws of the State of New York doing business in the City
County and State of New York United States of America), and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This Invention consists of a light tight box having a light tight passage way
for the movement of the paper sheet into or out of the box (the passage being light
tight both when the sensitized sheet is wholly within the box and when it is
being moved in or out of the same) a roller being mounted within the box and
made capable of being operated from the exterior of the box for winding on the
sensitized paper or sheet. The Invention also includes various other constructions
and combinations of parts whereby the efficiency of the case is very perfectly
secured substantially as hereinafter shown and described.
The Invention is applicable to carrying, preserving, and supplying as required,
all kinds of flexible sensitized tissue or paper whether sensitized on one or both
sides and whether used for making negatives or for photographic printing.
Reference is to be had to the accompanying drawing forming part of this
specification which illustrates the preferred form of construction of the case
embodying the Invention.
Figure 1. represents a view in perspective of the case closed, a portion of the
flexible sensitized tissue or paper carried by the case being shown as in the act of
being drawn therefrom.
Figure 2. is a perspective view of the case when open. Figure 3. is a longi-
tudinal section of the case closed, the roller being partly in elevation and partly in
section to show its journal bearings.
Figure 4. is a back view of the same and
Figure 5. a vertical transverse section upon the line x x in Figure 3.
Figure 6. is a transverse sectional view upon a larger scale of the roller which
carries the paper showing the means of attaching the paper to it.
The case as shown in the drawings consists of an oblong box or body part A
and correspondingly shaped lid part A¹ the two being hinged together as at a a.
The lid A passes when closed within end plates b b fixed to the ends of the body
part for the purpose of excluding light from the end joints of the case. The box
or case whether thus or otherwise constructed is provided with a longitudinal
passage way for the movement of the paper into or out of the box, and this
passage way is made light tight in any suitable manner. One method of making
said passage way light-tight and the one which is preferred is shown in the
drawings and may be described as follows:-L is a longitudinal opening in the
box the one edge of which is provided with a packing strip or wiper I of soft
flexible material such as cloth which forms the one lip of said passage way Said
wiper may be attached to the interior of the lid in any suitable manner when the

page_text: longitudinal opening L is formed as shown between the free edge of the lid and a
small longitudinal roller H which is journaled at its ends in the end plates 6 6 of
the box and constitutes the other lip of the passage-way. The wiper presses
against the roller and the two are so adjusted in respect to each other that the
passage way between them for the paper will be light-tight both when the paper
is therein and also when the paper is wholly withdrawn therefrom. To prevent
access of light to the interior of the box at the opposite side of the roller H another
longitudinal wiper J of suitable soft material is so applied as to bear against the
other side of the roller H this wiper preferably being double and bearing against
the roller H in opposite directions around its circumference as shown. This second
wiper. J may be attached to the interior of the body part of the case by any.
suitable means. The roller H also serves as a guide to the tissue or paper as it is
drawn out from the case. When the desired amount of paper or tissue has been
drawn out it is detached by tearing across the web close up to the guide roller Ḥ
thus leaving the remainder of the paper under the close and light tight cover of
the case. The two wipers I J also serve respectively to keep the roller H and the
tissue or paper free from dust thereby preventing injury to the sensitized surface.
of the paper by dust collecting on it.
Within the body part A is mounted a longitudinal roller B on which is wound
the flexible sensitized strip of tissue C the inner end of the roll or strip being
received in a longitudinal groove d in the roller and engaged with pins or pointed
teeth & therein whereby the paper is securely attached to the roller without being.
punctured otherwise than at its end and through a single thickness. The roller B,
which may be of wood or other suitable material, is provided with end caps or.
ferrules D carrying journals e which are mounted to turn in bearings formed on
the end plates 6 of the box. Both the journals e are socketted to adapt either of:
them to receive a key E (shown separately in Figure 1) for the purpose of rotating.
the roller B to wind up the paper either to fill the case or to take up any superfluous
paper that may have been drawn out. To check the turning of the roller B and
so facilitate the drawing out of the sensitive paper in desired quantities cupped
spring washers G are introduced between the ferrules or caps D and-the ends of
the case to produce an endwise pressure against the roller.
To more effectually exclude the light from the interior of the case when closed
the lid, has a close fit at its ends under cover of the end plates b b and a tongue
and groove fit as at g with the body part of the case along the hinged side and the
case is held close-shut and the wipers I J caused to press on the guide roller H
and tissue C passing over said roller by a spring strap or fastening K pivoted to
the ends of the body part of the case and passing longitudinally over the lid part
thereof. Or spring straps or fastenings K¹ pivoted to the body part at front and
back close to the ends of the case and bearing down on the lid transversely may
be used, said straps or fastenings being thrown off at the back or ends of the box
as the case may be in order to open the box when required; Other suitable
fastenings may be used.
The case as thus described for storing photographic sensitive paper may be
carried in the pocket or elsewhere without risk of exposing said paper to light or
dust and the paper may be torn off for use in lengths of any desired size without
affecting or exposing the remainder and the case will be found much more con-
venient in this and other respects than a portfolio carrying between its leaves
detached lengths or pieces of photographic sensitive paper.
