Improvements in Apparatus for Making and Exhibiting
Kinetoscopic Pictures.
We, JOHN HENRY HILL DUNCAN, of 39, Coleman Street, London, E.C., Chartered
Accountant, and THEODOR REICH, of 63, Maitland Park Road, London, N.W.,
Photographer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to improvements in apparatus for making and
exhibiting kinetoscopic pictures and it has for object inter alia to enable the
apparatus to be used not only for producing upon a suitably prepared strip or band a
number of successive photographs of a moving object or objects and for afterward
projecting or exhibiting such photographs, but also for making the perforations in
the edges of the strip necessary for intermittently feeding the same, through the
apparatus, thereby obviating the necessity, of employing a separate and costly
perforating machine as heretofore usual.
For this purpose there are used in conjunction with a guiding device for the
strip, and means for intermittently moving the strip forward, a punching device
comprising pins arranged to work through the guiding device and to perforate the
edge portions of the strip at right angles to its length, and operating mechanisın
adapted to be thrown in and out of action with the main driving shaft or other
movable part of the machine so that the punching device can be readily put in
and out of use, according to the purpose for which the machine is for the time being
to be employed.
Punching devices and operating mechanism therefor according to this invention
can be constructed in various forms.
In one arrangement in which the strip is fed through a vertical guide, the
punching device comprises a pair of pins carried by a plate and arranged to work
horizontally through holes at the sides of the guide. The pins are caused to make
their operative strokes at the required times by means of a lever arranged to be
operated at the required times by means of a cam fixed on a horizontal driving shaft
and to move the plate and pins against the action of springs which serve to effect.
the return stroke of the plate and pins and which are located between the guide and,
plate and may encircle the pins. To enable the punching device to be thrown out;
of action, the lever, which is arranged to work in a vertical plane in front of the guide,
may be made in two parts, viz. an upper and wer part, the parts being hinged
together in such a way that the lower parts can be brought into line with the upper
part whereupon it will be in position to be operated by the cam, but can be moved
into a position at an angle with the upper part when it is desired to put the punching
device out of use. Or the lever or cain may be capable of being displaced laterally.
when it is desired to put the lever out of action.
י
For intermittently moving the strip at the required times and to the desired
extent, there is provided at the back of the vertical guide according to one arrange-
ment, a rotary drum provided near its ends with pins spaced apart to suit the
required pitch of the holes in the strips and adapted to engage with holes that have,
already been formed.

page_text: An intermittent motion is imparted to the drum by means of a pawl that engages
a ratchet wheel on the drum and is carried by a lever arm to which an oscillating
movement is imparted through a link from a crank or equivalent device on the main
driving shaft which is arranged near the base of the machine and in front of a vertical
support carrying the guide. Backward rotation of the drum is prevented by a
gravity or spring detent and forward rotation is controlled by a pawl or stop carried
by a lever which is operated to release the drum at the required times by a cam on
the main shaft.
A roller or drum driven from the main shaft is or may be provided upon which the-
band may be wound after passing the pin drum, and a stripper plate may be provided
for preventing the band clinging to the latter drum.
The shutter is or may be a rotary slotted plate fixed upon a sleeve mounted to
rotate on a horizontal pin fixed to the upright carrying the guide and on which the
plate carrying the punching pins may be mounted to slide. The sleeve is or may be
rotated from the main driving shaft through a vertical shaft and a pair of bevel
wheels.
The apparatus is enclosed in a casing adapted to carry a photographic lens when
the apparatus is to be used for taking photographs and through which the light of a
lamp can be projected when the apparatus is to be used for exhibiting photographs.

Improvements in Apparatus for Making and Exhibiting
Kinetoscopic Pictures.
We, JOHN HENRY HILL DUNCAN, of 39, Coleman Street, London, E.C., Chartered
Accountant, and THEODOR REICH, of 63, Maitland Park Road, London, N.W.,
Photographer, 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 reference to improvements in apparatus for making and
exhibiting kinetoscopic pictures and it has for object inter alia to enable the
apparatus to be used not only for producing upon a suitably prepared strip or band
a number of successive photographs of a moving object or objects for afterwards
projecting or exhibiting such photographs but also for making the perforations in
the edges of the strip necessary for intermittently feeding the same through the
apparatus, thereby obviating the necessity of employing a separate and costly
perforating machine as heretofore usual.
For this purpose there are used in conjunction with a guiding device for the strip,
and means for intermittently moving the strip forward, a punching device comprising
pins arranged to work through the guiding device and to perforate the edge portions
of the strip at right angles to its length, and operating mechanism adapted to be
thrown in and out of action with the main driving shaft or other moveable part of
the machine so that the punching device can be readily put in and out of use,
according to the purpose for which the machine is for the time being to be
employed.
Punching devices and operating mechanism therefor according to this invention
can be constructed in various forms.

page_text: Referring to the accompanying drawings Figs. 1 and 2 illustrate in front and side
elevation respectively an arrangement of apparatus according to this invention in
which a celluloid strip 1 is intermittently fed through a vertical guide 2 at the
required times and the desired extent, by means of a rotary drum 3 provided near
its ends with pins 3* spaced apart to suit the required pitch of the holes to be formed
in the strip and adapted to engage with holes that have already been formed therein.
Intermittent motion is imparted to the drum by means of a pawl 4 that engages a
ratchet wheel 5. on the drum and is carried by a lever arm 6 which is oscillated
through a link 7 from a crank or equivalent device 8 on the main driving shaft 9
which is arranged near the base of the machine and in front of a vertical support
carrying the guide 2. Backward rotation of the drum 3 is prevented by a gravity
or spring detent 10 engaging the ratchet wheel 5 and forward rotation is controlled
by a pawl or stop lever 11 which engages a ratchet wheel 11" but is operated to
release the drum at the required times by a cam 12 on the shaft 9.
The punching device comprises a pair of pins 13 carried by a plate 14 and
arranged to work horizontally through holes 15 at the sides of the guide 1. The
pins are caused to make their operative strokes at the required times by means of a
lever 16 fixed to rockshaft 16* and operated by a cam 17 on the shaft 9 so as to
move the plate 14 and pins 13 against the action of springs 18 which encircle the
pins 13 between the guide 1 and the plate 14 and serve to effect the return stroke
of the plate and pins. To enable the punching device to be thrown out of action,
the lever 16 may be made in two parts as shown, viz. an upper and a lower part, the
parts being hinged together at 16ª in such a way that the lower part can be brought
into line with the upper part whereupon it will be in position to be operated by the
cam 17, but can be moved into a position at an angle with the upper part as
indicated, by dotted lines in Fig. 1 when it is desired to put the punching device
out of use. A spring 16 keeps the lower part in the required position. A lever
may be fitted at each end of the rockshaft 16*. Or the lever or cam may be
capable of being displaced laterally when it is desired to put the lever out of
action.
A roller or drum driven from the main shaft is or may be provided upon which
the strip may be wound after passing the pin drum 3, and a stripper plate 19

may be provided for preventing the strip clinging to the drum 3.
shutter which is or may be a rotary slotted plate fixed upon a sleeve 21 mounted on
a horizontal pin 22 on which the plate 14 may be mounted to slide as shown. The
sleeve is rotated from the shaft 9 through a vertical shaft 23 and bevel wheels 24, 24ª.
The apparatus is enclosed in a casing 25 and is provided with a photographic
lens 26 when the apparatus is to be used for taking photographs and through which
the light of a lamp can be projected when the apparatus is to be used for exhibiting
photographs.
Referring to Figs. 3 to 8 inclusive which illustrate a slightly modified construction,
Fig. 3 is a central vertical section through the apparatus ;
Fig. 4 a section on the line a a, Fig. 3 and Fig. 5 a section on the line bb, Fig. 3
Figs. 6, 7 and 8 are sectional detail views taken on the line c c, Fig. 3, d d and e e
Fig. 6 respectively.
In this construction the guiding device 2 and the means for intermittently moving
the strip forward (see Figs. 7 and 8) are arranged similarly to the corresponding parts
shown in Figs. 1 and 2. The punching device comprises a plate 14 mounted to slide
horizontally on guide pins 14" fixed to a plate 14b that is screwed to the back of the
guide 2, the plate 14 carries at opposite ends sets of rearwardly projecting pins 13,
the pins of each set being spaced apart to suit the pitch of the holes required to be
punched. The pins 13 work through correspondingly arranged holes in the sides of
the guide 2 and the plate 14b which forms part of the back of said guide. The
plate 14 is attached by pin and slot connections to the upper ends of a pair of
5 levers 16 pivotted at 16* whose lower ends can, when required, be brought into
position so as to be operated by a pair of cams 17 on the main shaft 9. Springs 18
serve to effect the return stroke of the punching device.

page_text: To enable the punching device to be thrown into and out of action the lower ends
of the levers 16 are connected by a rod 27, the opposite ends of which are respectively
formed with right and left handed screw threads fitting correspondingly screw
threaded holes in the ends of the levers. By turning the rod 27 in one direction or
the other the lever ends are displaced laterally towards or away from each other so
as to be brought under or removed from the action of the cams 17, as may be
required.
The holes 15 in the plate 14" are flared or bell-mouthed at the back so as to enable
the pieces of celluloid punched out by the pins 13 to be readily ejected; these pieces
of celluloid fall into a shoot 28 which conducts them to the outside of the casing of
the apparatus.
29 and 30 are the rollers on which the strip is wound; the latter is driven from
the shaft 9 by an elastic band 31 as shown in Fig. 3. 32 is a spring pressed grooved
roller adapted to keep the strip in engagement with the pin drum and 33 is narrow
strip of velvet which serves as guide for the strip. The shutter 20, which is a
segmental piece of celluloid, mounted on a horizontal shaft 20* carried in a long
bearing 20ª
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In apparatus for making and exhibiting kinetoscopic pictures the combination
of a guiding device for the strip, means for intermittently moving the strip forward,
a punching device comprising pius arranged to work through corresponding holes in
the guiding device and to perforate the edge portions of the strip, and punch operating
mechanism adapted to be thrown in and out of action, substantially as described.
