Above is what one looks like. Below is my translation of the rather self-congratulatory French Instructions for the Coq d'Or. Feel free to scoll down to the more interesting part.

"Creating a new 9.5mm projector combining all the qualities of its various predecessors, giving this new projector a modern and elegant shape, ensuring maximum simplicity of loading and operation, giving it the maximum light output and steadiness, all for the lowest possible price for a machine with such features; such were the challenges faced by Pathé-Baby Technical Staff.

In creating the Coq d'Or, the first in a series of related machines, Pathé-Baby took inspiration from the old G2 projector, the first model of which was successively developed over a period of 15 years as well as from a number of subsequent projector models. All the refinements developed over time are combined in the Coq d'Or which, moreover, is notable for its solid construction, making it virtually indestructible.

This machine, which uses as its light source the Type "O" lamp (60v 50w) from the Lux, will give a perfect picture on a screen of around 1.25 metres. Larger-scale projection remains the preserve of machines with more powerful lamps of up to 400w.

In summary, all the films from the fascinating Pathé-Baby 9.5mm library, without exception and whether with notched or running titles, can be shown on the Coq d'Or to audiences of up to 50.

Features of the Coq dOr

  1. Projection of all Pathé-Baby films of 10 or 20 metres, with or without notched titles.
  2. Perfect illumination, rock steady pictures.
  3. New system for stopping on titles without re-framing
  4. Silent projection of titles as the mechanism is disengaged
  5. Wide-aperture shutter with a single blade/flicker blade turning at twice normal speed
  6. Safety shutter automatically protects the film if projection slows or stops
  7. A single type of lamp (model O 60v 50w) proved in previous models (giving maximum light output consistent with showing notched titles without damaging the film).
  8. Built-in resistance in the base of the machine allows operation from AC or DC supplies from 105 to 125 volts.
  9. Maximum lamphouse opening to give maximum accessibility for threading
  10. Faultless take-up in the lower part of the projector thanks to the film engaging mechanism at the centre of the rotary disc, operation being simplified by a fully opening cover
  11. Focussing by a lever on the lens
  12. Positive-action lamphouse closing

13. Still frame projection at any point in a film

14. Adjustable feet for centring the image on the screen.

Setting Up The Projector

The apparatus is delivered ready to use.

The lamp is already fitted, all you have to do is fit the winding handle on its shaft after unpacking. Nonetheless, it would be sensible to check the lamp has not been displaced in transit. Open the lamphouse by loosening the knurled knobs (A) on either side. Pull the lamphouse cover backwards, using the nickel-plated knob (B in Fig. 4) and check that the T piece for locating the lamp is pushed right down into its slot at the rear of the lampholder, tighten the knurled retaining screw (not too tight), then replace the cover, tightening the knurled knobs (again, not too tight).

Connecting the Projector

The machine is delivered with a mains lead. Check the precise mains voltage and move the cursor (C) to the corresponding figure on the resistance before connecting to the mains.

The lamp will come on immediately but the automatic shutter prevents the light passing through the film.

It is therefore necessary to crank the handle to get light on the screen.

Adjusting Picture Height

Adjustment is by turning the two feet (D) at the front of the projector. The feet of the Coq dOr are fitted with rubber to avoid damage to furniture.

This arrangement also allows the projector to be levelled if it is used on an uneven surface.

Threading

Now the machine is ready for use. To load film, proceed as follows.

1. Open the upper cover (E) and place the film cassette on the spindle, with its opening facing the lamphouse. After closing the cover, adjust the cassette slightly until the lugs on the cover engage with the slots on the cassette, locking it in position.

2. Open the lamphouse by pressing the catch (G) on the upper right hand side of the projector, as viewed from the back.

3. Pull about 20 cms of film from the cassette, open the lower chamber cover and attach the end of the film to one of the slots in the take-up core. The film should pass over the upper roller (J), between the gate guides and then under the lower sprung roller (K). Close the lower chamber cover.

4. Holding the film in position, close the lamphouse by simply pushing it forward until it automatically locks in place.

5.Turn the handle, holding the projector steady to avoid vibration affecting the steadiness of the picture.

6. Focus the picture on the screen with the lever (N), raising or lowering the lever to get maximum sharpness.

7. To show a still at any point in the film, (for a maximum of four seconds), simply press the small lever (O) to disengage the mechanism. To stop for longer, press the lever again once the previous frame has moved on.

8. Continue cranking to the end of the film; titles will stop and the film will restart automatically and the film will stop automatically at the end thanks to the patented cassette system.

Rewinding

Once the film has ended, open the lamphouse as for loading, disengage the claw by gently moving the crank handle, then turn the upper crank (P) anti-clockwise. In a few seconds, the film will be completely rewound into its cassette , ready for another showing.

Maintenance

From time to time, remove the guard by loosening the three knobs (R) and put a drop of the special Pathoil (Ref F 21) on the cam and the bearings.

After each show, clean the fixed and sprung gates to remove any particles of film that may have built up.

It is advisable also to clean the condenser (from inside the lamphouse???) and the lens which can be accessed from inside the mechanism guard???

From time to time, oil the shutter bearing inside the lamphouse.

Properly maintained, the Coq d'Or will last indefinitely, no part being susceptible to breakdown.

Super Attachment for the Coq d'Or

The Super Attachment for spools of up to 100 metres consists of two arms fixed to a bracket, which has a "buttonhole" at the top and a slot at the bottom. Mounting is extremely easy, just loosen the two nickel knobs on the front of the machine by a few millimetres to insert the bracket and then re- tighten.

The lower arm carries a pulley to take the drive belt, which runs from the pulley (U) beneath the crank handle. This drives the film take-up.

The upper arm also carries a pulley (V) which, after projecting the film, should be connected to the upper pulley (X) next to the rewind handle (P) with the rewind belt. This pulley, driven by the rewind handle turned anti-clockwise will very quickly rewind the film onto the empty spool on the upper arm.

NOTE. The same belt serves both to take up the film onto the lower spool and then to rewind onto the upper spool.

Special Coq d'Or Motor

The special drive motor for the Coq d'Or is mounted on a base for instant attachment to the rear of the projector.

Two nuts and bolts (Z) are provided with the motor. These are fitted to the two holes in the base of the projector, after loosening the wing nuts almost completely, then re-tightening by a quarter turn to ensure they don't fall off. (???).

To fix the motor, simply connect the power plug in the base to the two pins at the rear of the projector, pushing it well home, then move the two bolts (Z) to the rear (???) and tighten them securely. Finally, connect the motor pulley (Pm) to the large projector pulley (Pp) to complete assembly.

The base of the motor has a switch (Ir) on the right and a rheostat (Rh) on the left for controlling the speed of the motor. The switch controls the current to both the lamp and the motor.

Connection to the power supply is made in exactly the same way as for the projector itself."

Coqs d'Or are supposed to be rare, but there seems to be a small breeding colony somewhere south of the Midlands; the late Bob Andrews had one, used to illustrate the instructions above, Willem Hackmann seems to have two, (one of which can be seen below), and I, too, now have one, albeit a humble hand-cranked machine with no Super Arms.

Above is the stand-alone version (please excuse oddity of images as thay were taken against a red background a long time ago) and one of Willem's machines. Those Super Arms look as if they might be copyable.......

Also, I subsequently acquired Bob's Super-Armed machine, only to find an interesting problem. When we tested it chez Bob, we found the pic was a bit lacking in height, and the masking gave a very fuzzy edge. These pictures show you why and what I plan to do, and I have added a chitterlings pic.

Someone appears to have tried to reduce the aperture mask in height, rather badly, making it 5.3mm instead of 6.5!. In addition, the design is such that the film is separated from the top and bottom masking by not only the thickness of the gate aperture plate, but also by the thickness of the relief area on the back - the central vertical area shown in the first sketch. The movable mask, which is flat, rides on this area and on the "shoes" formed by the strips cut in the side of the plate (see second sketch). With such a gap, no wonder the image was fuzzy.

I have had a go at making a new aperture plate for the Coq d'Or (see above). The principle is sound, and I get the aperture closer to the film but, this being, as so often for me, a prototype, I made mistakes and ended up with too big an aperture. Rather than re-make the whole thing, I found that it was a good carrier for a Pathé Baby aperture mask, which has a properly raised-edge aperture and does a very good job. 

If anyone already has a Coq, a word of advice. One of the features of the Coq is that it has the shutter between the lamp and the film. This of course drastically reduces the amount of heat from the lamp which reaches the film as the shutter absorbs a lot of it. It is possible therefore to use a higher-powered lamp without frying the titles. As part of the same assembly, there is also a centrifugal shutter, designed to block the light and heat from the lamp if the rate of cranking falls too low or stops. It is easy to re-assemble this wrongly if you remove it - I found it wrong on both of my machines. There are two stops which limit the travel of the centrifugal shutter - get it the wrong side of these stops and it won't do its job. The correct way is obvious when you can actually see it. 

Now for a bit more about the mechanism, especially the notching mech. The next two pix show how the lamphouse and main machine come together. The aperture plate and one half of the dog clutch fro the shutter drive are in pic 1, with the shutter, centrifugal heat filter, sprung gate and the other half of the dog clutch seen in pic 2 of the front face of the lamphouse.

Now for the notching mech.

Pic 1 is a general view of the exposed mech. Pic 2 shows the front, fixed gate, pic 3 the other side. Then finally we have two close-up views of the "star wheel" that provides the notching effect.
