Improvements in Dark Slides for Photographic Purposes.
I JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of
Middlesex Gentleman do hereby declare the nature of this invention which
invention has been communicated to me from abroad by Paul Tournachon of
58 Chaussée d'Antin Paris in the Republic of France Photographer, to be as
follows:-
My invention relating to dark slides for photographic purposes consists in
improvements in the construction and arrangement of the parts connected with
the film carriers and is partly applicable to other dark slides, as] hereinafter
explained.
The dark slides according to my invention enable a large number of exposures to
be made upon the paper or film which is of considerable length and an indicator is
employed to show the number of exposures.
The supports of the rollers slide into a light tight case closed in front by a
shutter which is removed during exposure and inserted for the time into a groove
or slot at the back.
When the shutter is removed the opening through which it is withdrawn is
instantly closed by a transverse slide actuated by a spring and provided with an
incline or bevel enabling it to be pressed back when the shutter is returned to its
place.
This transverse slide also exerts upon the shutter sufficient pressure to insure the
effectual exclusion of light. These arrangements are applicable to dark slides of
any construction.
The spool is composed of four segments so put together as to present two longi-
tudinal openings arranged at right angles and turns on two fixed pivots. A disc at
one end of the spool carries pins which engage in holes in the end of the spool.
The end of the film is inserted into one of the longitudinal openings and is secured
by a plate sliding in the other opening arranged at right angles with the first, so as
to bend back the end of the film and retain it firmly in position.
The receiving roller is similarly constructed and is capable of being rotated from
the exterior by means of a hinged key or folding handle.
The movement of the film or paper is controlled by a pivoted brake spring with
two arms whose extremities engage with the toothed edges of discs connected with
the spool and the receiving roller. A lever pressing the brake arm against a fixed
stop compels the brake to exert a constant or uniform pressure upon the roller discs.
Owing to the shape of their teeth these dises and consequently the rollers with which
The brake can be released by
they correspond can only turn in one direction.
removing the pressure of the lever.
The said lever is retained in position by a spring catch which when released
enables the roller and spool to turn freely in either direction.
The perforating or registering roller is fluted to prevent slipping of the paper or
film and is of such diameter that when it has made exactly two revolutions for

page_text: example sufficient of the film is unrolled for one exposure. Inside the registering
roller is a roller of smaller diameter rotating in bearings in the ends of the registering
roller. The small roller is arranged eccentrically to the registering roller and a
wheel on the axis of the eccentric roller gears with a pinion having for example
half as many teeth as the wheel on the axis of the registering roller.
A series of small blades or prickers carried by the eccentric roller project through
openings in the side of the registering roller when the eccentric roller is in a certain
position and the relative diameters of the gearing is so calculated as to cause the
said prickers to project once for every two revolutions for example of the registering
roller and cause the successive negatives to be separated from one another by a
series of holes.
The film drawn from the spool passes over the perforating or registering roller
and is drawn in front of the slide where it is exposed. It then passes round a plain
guide-roller and is wound upon the receiving roller.
The number of exposures is indicated by the number of revolutions made by the
registering roller. This number is recorded by two discs, one disc indicating units,
and one indicating tens for example. These discs are concentrically arranged, the
disc for the tens accomplishing the tenth part of a revolution while the unit disc
makes a whole revolution. The figures are preferably formed on the flat sides of
the discs in order to economise space and enable the counter to be contained in the
thickness of the side of the case. A stud or pin on the end of the registering
roller drives a star wheel intermittently causing it to advance one a tooth at each
revolution of the roller and this movement is transmitted to the indicating or
registering mechanism by suitable gearing.
The tens disc rotating concentrically with the unit disc is provided with ten
equidistant holes which successively coincide with a hole in the unit disc situated
on the radius corresponding to zero. A spring pin enters this hole so as to lock
the discs together.
A metal plate covering the indicator mechanism is provided with an orifice
showing the figures and also enabling the inclined extremity of spring of the locking
pin to move forwards each time that the zero is presented at the orifice. This
movement locks the unit disc and tens disc together once at every revolution of the
unit disc and displaces the tens disc to the extent of one figure after which the
inclined end of the locking spring comes in contact with the edge of the orifice in
the covering plate and releases the said tens disc which then remains stationary
until the unit disc has completed another revolution.
Each time the indicator advances a unit the end of a spring falls from one tooth
to another of a ratchet wheel causing a clicking sound indicating that the roller has
been sufficiently rotated. This device also renders it impossible to turn the roller
and counter the wrong way.
The ratchet wheel may be arranged to actuate a bell or other sounding device.
A tension roller is carried by two springs which cause it to press regularly on the
paper or film.
The plates carrying the journals of the rollers are connected and stayed by
suitable rods and the plates at the sides are cut away and recessed to facilitate the
working and the insertion of the film.
Hinged flaps are provided at the sides of the slide to prevent the film getting
torn at the edges when sliding the plates carrying the rollers into the outer case of
the slide.
To obviate the waste of paper or film in roller slides arranged as herein described
or otherwise and which is involved by the ordinary methods of attaching the ends
of the films to the rollers I attach to the end of the film a linen band of the ame
width as the film and to this linen band is attached a spring clip one of the jaws of
which is provided with a slot or opening. The film is drawn between the jaws and
the end inserted into this slot, and secured by sliding a rectangular binder or wire
over the projecting end of the film. This linen band is then attached to the roller
and replaces that portion of the film which would otherwise be wasted.

by the usual sliding motion or in any other suitable manner.

COMPLETE SPECIFICATION..
Improvements in Dark Slides for Photographio Purposes.
I, JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of
Middlesex, Gentleman, do hereby declare the nature of this invention (which has
been communicated to me from abroad by Paul Tournachon of 58 Chausséo
l'Antin, Paris, in the Republic of France, Photographer) and in what manner the
ame is to be performed to be particularly described and ascertained in and by
he following statement :—
This invention relating to dark slides for photographic purposes consists of
improvements in the construction and arrangement of the parts connected with
6lm carriers and is partly applicable to other dark slides as hereinafter explained.
The dark slides made according to this invention enable a large number of
consecutive exposures to be made upon the sensitised material which is enabled to
be made of considerable lengths. An indicator or registering mechanism is also
provided shewing the number of exposures that have been made and enabling the
quantity of unexposed film or material remaining in the apparatus to be readily
ascertained.
And in order that my invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
several figures on the annexed sheets of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 represents in vertical section an apparatus constructed according to this
invention the section being taken on the line - Figure 2.
Figure 2 is an elevation partly in section in order to shew the internal mechanism
of the indicator or counter.
Figure 3 represents in elevation the part or end provided with the indicator.
Figure 4 is the end of the frame opposite to that which carries the indicator.
Figure 5 is a perspective view of the case into which the film carrier is
inserted.
Figure 6 is a perspective view of the frame in which the spool or roller
mechanism is supported.
I will now proceed to explain the construction and action of each of the parts of
the improved film carrier as constructed according to this invention.
The dark slide properly so called consists of:-
A spool or roller for carrying the film or sensitised material and on which the
said film or material is wound and which may be of a length sufficient to allow of
one hundred exposures for example.
A perforating or registering roller or cylinder for separating the successive
negatives from one another by piercing a number of small holes along the lines
where the film is to be divided in order to separate one picture from another.
A guide roller arranged in the lower part of the frame.
A receiving roller on which the film is wound after exposure situated at
the bottom of the slide and worked by means of a key or handle from outside
the cave.
A spring-brake acting simultaneously upon the spool or roller which carries the
film and upon the receiving roller on which it is rewound the said brake serving t
prevent these rollers from rotating in the wrong direction or running back and
unwinding the film except when the operator manipulates the key.,

page_text: An indicator arranged in connection with the perforating cylinder and serving to
register the number of exposures made. This indicator is provided with an alarum
or sounding device consisting of a spring acting upon the teeth of a spur wheel,
and emitting a clicking sound which warns the operator that a length of film
necessary for one exposure has been unrolled.
A tension roller carried on springs and acting on either side of the film in order
to impart to it a constant and uniform tension, if owing to any cause it tends to
expand.
The film on being unrolled from the spool or film carrier (13 Figure 1) passes
over a perforating cylinder 21 and descends in a line parallel to the face of the
slide, it then passes round the guide roller (28) and is rolled up on the receiving
roller (13').
The support of the rollers is inserted like a drawer into a light tight case 1 as
represented in Figures 5 and 6 and in section in Figure 1.
This case is closed in front by a screen or shutter 2 which is removed during
exposure and inserted when not in use into a groove or slot 3 at the back of the
case.
When this shutter is removed the opening through which it is withdrawn is
automatically closed by a transverse slide 4 which is actuated by a spring 5, and
effectually excludes the light.
This slide 4 as shown in Figure 1 is inclined or bevelled at its front edge in such
a manner that when the screen 2 is re-inserted its edge presses upon the inclined
edge of the slide + and forces back the latter at the same time compressing the
spring 5.
This transverse slide also exerts upon the shutter sufficient pressure to
insure the effectual exclusion of light and may be employed with a dark slide of
any construction.
The several mechanical parts and details of the improved slide are described
as follows:-
1st. The spool or roller for carrying the film. This spool is 13 composed of four
segments (Fig. 1) so put together as to present two longitudinal openings or slots
arranged at right angles to one another and carries wound upon it the supply of
sensitive material, being arranged to rotate upon two fixed pivots or studs 9 and 10
carried by or fixed in the top and bottom plates 7 and 8 of the slide. A notched
or toothed disc 11 rotating freely upon the pivot 10 at one end of the spool 13
carries studs 12 which engage in recesses or sockets in the end of the spool so as to
cause the spool to rotate with the disc.
The arrangement for attaching the end of the film to the roller or spool 13 is as
follows: the end of the film is inserted into a longitudinal slot or opening 24' formed
in the roller 13 as represented in Figure 1 and is secured by a transverse plate or
wedge 25' inserted into another slot formed at right angles with the slot 24' so as
to enable the wedge 25' to bend back the end of the film and retain it firmly in
position. The film is wound upon the roller by rotating the latter and the
successive thicknesses of film cover the end of the key or wedge 25'. This arrange-
ment has the advantage of enabling the film to be inserted into either of the
two grooves or slots by simply inserting the key or wedge 25' into the other slot at
right angles to the first. By this means facility is also afforded for securing
the film or sensitive material taut and parallel to the front of the slide without
waste.
2nd. The receiving roller 13. The arrangements of this roller as regards the
pivots and the means for fixing the film are the same as in the case of the roller or
spool 13 the roller 13' being provided with a toothed disc 11' and the end of the
film being inserted into a slot 24" and secured by a wedge 251 but the receiving
roller 13 receives its rotatory motion from outside of the case being actuated by a
handle or key 14 Figure 2 hinged at the end of its axis. By this motion the film
is uncoiled from the spool 13 and is wound upon the receiving roller 131.
3rd. The brake. The movement of the film or paper is controlled by a brake

page_text: onsisting of a spring arm 16 pivoted at 16' and whose extremities form two
etents 15 and 15' engaging with the toothed edges of the discs 11 and 11' on the
pools 13 and 13'. After these spools have been placed in position the brake is
djusted in the position shewn in Figure 1 with one arm of the brake bearing
gainst a pin 17 fixed in the front wall of the slide. A lever 18 is then adjusted
pon its centre 19 so as to cause it to press the brake arm against the fixed stop 17.
In this position the brake 16 keeping the said arm pressed against the stop 17
compels the brake to exert a constant or uniform pressure upon the discs 11 and 11'.
Owing to the ratchet shape of their teeth these discs, and consequently the rollers
or spools with which they correspond, can rotate only in the direction shewn by
the arrows in Figure 1 and remain stationary except when the key 14 is
manipulated.
spring catch and can be
A hole 20 is formed in the lover 18 which acts as a
caused to engage with a pin fixed in the wall of the slide. This pin when engaged
with the hole in the lever retains the latter in the desired position. By disengaging
the lever from the pin the roller 13' and spool 13 arc enabled to rotate freely in
either direction the discs 11 and 11' being released from the action of the brake
lever 16.
4th. The perforating and registering roller marked 21, Figures 1 and 2 is hollow
and preferably made of metal. Its surface is fluted or roughened to prevent
slipping of the paper or film and it 'is of such diameter that the unwinding of a
sufficient length of the film for one exposure causes it to describe exactly two
revolutions (for example). It is consequently necessary in order to avoid having
the negatives perforated in the middle to arrange the cylinder in such a manner
that the perforating does not take place until after the cylinder has completed two
revolutions. With this object the cylinder is provided with mechanism as herein-
after explained.
Inside the cylinder 21 there is a smooth roller 22 of smaller diameter. The
pivots of this roller work in bearings in the end of the cylinder 21 and on one end
of the roller there is a toothed wheel 23 (shewn in dotted lines in Figure 1) having
twelve teeth which gear with a pinion 24 having only six teeth and whose nxis
coincides with that of the hollow cylinder 21.
The internal roller 22 is provided along a generating line with a series of small
double edged blades or prickers 25 which project through openings 26 provided for
this purpose in the side of the fluted cylinder 21. The manner in which this
When the cylinder 21 and roller 22 are placed in
arrangement acts is as follows.
the position shewn in Figure 1, the pointed blades or prickers 25 project through
the side of the cylinder 21. Now when this cylinder 21 is caused to describe one
revolution the roller 22 after having accomplished its revolution round the axis 24
of the cylinder 21 returns to the position from which it started but at the same
time it will have described exactly half a revolution on its own axis as the wheel 23
has double the number of teeth as the pinion 24. The points 25 will consequently
be directed towards the centre of the cylinder 21 instead of projecting through the
openings in the periphery of this cylinder as represented in the drawing It is
evident that as the cylinder 21 is caused to rotate by the action of the film, the
prickers 25 will be protruded once for every two revolutions of the cylinder and
the film will be perforated at corresponding intervals that is to say every time that
the cylinder describes two revolutions upon its own axis, the successive negatives
being separated from one another by lines of perforations.
5th. The guide-roller. The film as it is drawn from the spool 13 passes over the
perforating and registering cylinder 21 and is drawn in front of the slide over a
Hat plate 27 where it is in a position for the exposure. It then passes round a plain
guide-roller 28. This is simply a cylinder which rotates under the action of the
film and changes its direction so as to direct it to the winding or receiving
roller 131.
6th. The indicator. In order to ascertain the number of exposures it is sufficient

page_text: to count the number of revolutions made by the registering and perforating
cylinder 21 which describes two revolutions for each negative. The indicator
which performs the counting operation consists of two discs 29 and 33 (shewn in
section in Fig. 2 and in dotted lines in Fig. 1) one disc indicating units and one
indicating tens (for example).
The face of each disc carries all the numerals up to 9 and consequently displacing
them relatively to one another. 99 numbers can be formed in the usual manner as
in the case of other types of indicators. The characteristic peculiarity of the
indicator now under consideration is that the two wheels are concentrically arranged.
The disc for the tens accomplishing a tenth part of a revolution whilst the unit
disc describes one whole revolution. The figures are preferably formed on the flat
sides of the discs (Fig. 3).
The disc 29 (Fig. 2) indicating units is carried on a spindle 30 receiving motion
from a star wheel 31 provided with twenty teeth. A small stud or tappet 32 on
the end of the hollow perforating cylinder or registering roller 21 drives the star
wheel 31 intermittently causing it to advance to the extent of one tooth at cach
revolution of the roller that is to say one twentieth of a revolution. The unit disc
partakes of this movement and consequently describes one tenth of a revolution or
advances to the extent of one unit for every two revolutions of the perforating
cylinder 21 thus indicating in units the number of negatives exposed. This disc
acts alone until the number 9 is reached when it causes the tens disc 3.3 to rotate
describing one tenth of a revolution at a time.
The tens disc 33 arranged concentrically with the unit disc is driven by friction
and is provided with ten equidistant holes 34 arranged in a circle concentric with
the disc. These holes coincide in succession with a hole 35 formed in the unit disc
and situated on the radius corresponding to the zero point on this disc. A pin 36
carried by a spring arm 37 projects into the hole 35 in the disc 29 being pressed by
the spring against the inner surface of the unit disc 29 so as to lock the two discs
together.
This spring arm 37 is arranged under the discs and is formed with an opening
through which the spindle 30 is passed as represented in Figure 2. One end of
the arm is screwed to the disc at 38 and the other or free end is bent outwards
at 39 so as to press against the inner surface of a cover plate 40 which is placed
over the discs. This plate 40 covering the whole of the indicator mechanisin is
provided with an orifice at 41 (Figure 3) through which the figures are visible.
When the end 39 of the spring arm 37 comes opposite to the orifice 41 in the
plate 40 the arm springs outwards and the locking pin 36 connects the unit disc
and tens disc together by engaging with one of the series of holes provided for the
purpose in the tens disc. This occurs once at every revolution of the unit disc and
has the effect of displacing the tens disc to the extent of one figure after which the
inclined end 39 of the locking arm comes in contact with the edge of the orifice in
the covering plate 40 and releases the said tens dise which then remains stationary
and independent of the unit disc until the latter has completed another revolution.
The object of the circular recess 41' in the plate 40 is to enable the spring 37 to
be liberated shortly before it is time for the locking pin to engage with the tens
disc so as to ensure the proper action of the locking pin.
The axle of the indicator also works an alarum or sounding device consisting of
a ratchet wheel 42 (Figures 1 and 2) with ten teeth for example presenting at
their extremities a smooth surface perpendicular to the radius in whose direction
they lie.
A spring 43 (Figure 1) presses constantly upon the teeth of this spur-
wheel. This spring being bent as represented in the drawing is screwed to the side
of the case at one end and each time the indicator advances to the extent of oue
unit the other or free end of the spring 43 passes from one tooth to another of the
ratchet wheel causing a clicking sound which indicates that the roller has been
sufficiently rotated and that the operator should cease turning the key 14.
Before passing from one tooth of the spur-wheel to the next, the spring stops

rection of the axis of rotation of the ratchet wheel 42 thus rendering it impossible

e arranged to actuate a bell or other sounding device if preferred.
1. The tension roller. This is a roller 44 Figures 1 and 2 of small diameter
omposed of wood or other material being of a length corresponding to the width of
he film. The axis of this roller works in bearings in the ends of two springs 45
od 45' which cause it to press constantly on the band of sensitive material passing
rom the spool 13 to the perforating cylinder 21 so as to keep it always taut
otwithstanding any expansion to which it may be liable owing to heat moisture or
ny other causes. The plates 7 and 8 carrying the journals of the rollers are
connected and stayed or maintained at the proper distance apart by menus of a
ransverse bar or rod 46.
Figures 4 and 6 illustrate the form of the said plates a portion of the plate 7
being cut away in order to facilitate the manipulation of the internal mechanism
and diminish the weight.
The plate 8 is recessed as represented in the drawing for the reception of the
indicator mechanism.
Hinged flaps 47 and 47' Figure 6 are provided at the sides of the slide in order
to prevent the film from getting torn at the edges when sliding the plates carrying
the rollers into the outer case (Figure 5).
Figures 7 and 8 of the accompanying drawings represent a novel arrangement
for connecting the ends of the sensitive material to the spools and which may be
applied to any form of dark slides or film carriers.
Apparatus of this type as hitherto constructed bas usually suffered from the
following disadvantage. When the end of the film is attached directly to the
receiving roller, the part of the film between the guide roller and the end of
the film cannot be exposed and comes out blank in developing, causing a loss of
developer which is of importance.
attached to a linen
band 48 of the same width as the film and to the edge of which this linen band is
rivetted a metallic spring clip 49 one of the jaws of which is formed with a slot or
opening 50.
To obviate this useless waste of material the end of the film
The film is passed between the jaws of the clip and the end being drawn through
the slot 50 is secured by sliding a binder or wire 51 over the projecting end of the
film as shewn in Figure 8. This linen band is then attached to the spool or roller
by means of an arrangement such as that herein before described with reference to
Figures and 2 or otherwise and replaces that portion of the film which would

constructed according to this invention may be attached to the camera by the
usual sliding motion or in any other suitable manner.
The slides may be made of any dimensions shapes proportions and materials and
the relation of the gearing connected with the perforating cylinder may evidently
be modified according to the dimensions of the slide without departing from the
principle of this invention.
