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
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.
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 because heat output may melt 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.
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 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.
- 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.
Polish the lens ‘O’ and the electric globe wth a soft cloth or chamois. Polish condenser ‘R’ on both faces. 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.
