Introduction
Because the 'Baby' Projector is constructed on a
miniature scale for Home use, one must not be misled into
the belief that is a Toy. On the contrary; built on the
soundest principles, the 'Baby' Projector is a machine in
the perfecting of which, Science, Mechanical Accuracy,
Skilled Workmanship and Experience of over 25 years have
been devoted.
The 'Baby' Projector contains in its mechanism the
greatest simplicity combined with the utmost efficiency
and absolute safety. As will be seen in [these
instructions] the operating of the 'Baby' Projector
is a matter of which a child of ordinary intelligence can
learn in the course of an hour or two.
To Prepare for
Use
On opening the case containing the machine all
necessary accessories for projecting perfect pictures
will be found.
The outfit comprises:
- The complete mechanism together with resistance
coil and connecting wire with plug
- An electric bulb
- The handle
- A rubber mat
- Book of Instructions
The
Screen
Whilst it is possible to project perfectly clear
Pictures on the wall, or any white surface, it is
advisable, to obtain absolute definition and sharpness,
to use the extra luminous screen specially prepared in
the same way as those used in the leading Cinemas.
This screen, kown as the 'Baby' Silver Sheet, may be
obtained at a small cost from the 'Baby' Projector
Department, in two different sizes, and should be placed
directly facing the projector at a distance of 10 feet
for a small size, and 16 feet for the larger.
A slight forward or backward movement of the apparatus
will bring the projection in perfect alignment with the
area of the screen.
The
Projection
Having removed the apparatus from the case, place the
machine on the rubber mat supplied to save the table from
scratches.
Screw handle 'F' on its axis. (fig. 4).
To Place Bulb in
Lantern
(The lamp for this machine is no
longer available - fitting a substitute is complicated by
problems with heat output melting the
film.)
Slightly loosen the screw at 'Z' (fig. 4), pulling out
the case 'N' (fig. 5) and gently fix lamp in socket.
NOTE:- Take care to see that the tenon 'a' of the lamp
is fixed securely into the slot 'b' of the socket (fig.
1).
Remove lamp from an ordinary electric light, and
replace with bayonet attachment at the end of the
insulated wire. Fix current plug 'Y' as shewn (fig.
5).
(note: I have left this in but I believe this method
of connection is no longer considered wise or safe - but
then, machines of this age should only be used with
extreme caution and after an overhaul)
Placing the
Film
Lean the lantern towards the rear by ressing it
downward and outward, supporting it till it rests. Take
care not to force the lantern open or closed.
Always use the down and outward pressure to open, and the
downward pressure to close. Open the gate 'B' and attach
Film spool to axle, turning the opening on the spool
towards rear of apparatus, and engaging the tenon 'C' of
the shutter in the notch 'E' in the case of the
spool.
Unroll two or three inches of the Film, which should
be drawn with the right thumb and index finger out of the
spool, over the roller guide 'L' into the opening of the
passage 'M', communicating with the lower magazine 'T',
in front of the hinge of the lantern, until the long
notch 'g' of the Film (Fig. 2 and 3) is presented in
front of catch 'J'. Replace the lantern but take care not
to displace the Film.
Turn off the room light by means of the two-way
switch. Simply press the button which automatically
lights the projector lamp, whilst extinguishing the room
light.
All is now ready for projection.
Showing the
Picture
The operator should sit immediately behind the
apparatus, holding his left hand on the side of the
machine to steady it. With the right hand grasp the
handle firmly and turn with an easy smooth notion. As
soon as the first picture appears it should be focussed
and the lighting regulated.
Focussing
- Move the screen, or apparatus, according to the
size of picture required.
- Move the button 'G' (fig. 5) forward or backward
until the picture appears clear and sharp.
- To make certain of a yet better result, one could
in the course of projection, focus by a particular
details, object, clear lines, or by any figure
situated in the foreground of the picture
Provided the screen or apparatus is not moved again
this focussing will suffice for the entire
projection.
Regulating the
light
Move the lever 'X' of the Rheostat Regulator in the
base of the apparatus towards right or left, till a soft
light untiring to the eye is obtained.
Masking the
Film
Push upwards or downwards the button 'I' situated on
the back edge of the left-hand side of the machine until
the projection of the perforations can no longer be seen
above or below the projected picture.
Studying the
Picture
Recommence the movement of rotation, regulating the
pace to such an extent that the spectators have time to
read all titles clearly. An important advantage is that
without danger one may stop rotating during a picture or
title as long as required.
This exclusive feature of the 'Baby' Projector is of
incalculable value to artists, sportsmen, schoolteachers
and others in enabling them to make a detailed
examination of certain subjects.
Rewinding the
Film
Lean the lantern towards the rear (see 'Placing
the Film'), disengage the film, if necessary, from
the pin by drawing it lightly out of the track, grasp the
little handle 'D' and turn anti-clockwise. In the event
of resistance during rewinding, do not force, but turn
handle 'F' a few times anti-clockwise so that the
unrolled film occupies the lower magazine 'T'.
When spool is rewound disengage it and attach the next
to be projected.
Useful
Hints
Polish the lens 'O' and the electric globe wth a soft
cloth or chamois. Polish condenser 'R' on both faces
(fig. 6). Clean the surfaces of the door and the film
track so that no dust or grit be left. For this purpose
use a little bone scraper - not a hard metal one which
would scratch the surface. Wipe both faces of the
projection lens.
Do not allow dust to accumulate in the magazine 'T'.
Oil the mechanism regularly with the special oil
provided. Place sparingly with the point of the can one
drop only in the holes which lead to the axles, and in
general on every part where there is friction or
movement.
