Soennecken Help!

[Raif79]

Bad day! I was turning the collar around the button on my Prasident 1 and heard a click. The button then fell out. The stalk that attaches to the button snapped. The metal was so brittle and just crumbled as I attempted to repair it. The button assembly is ruined. Now I'm left with a beautiful pen with a broken filling mechanism.

 

I'm in a panic. Any ideas?

A picture showing the broken part could help……..

Below a rough sketch showing the principle of the Soennecken "safety push knob filler" system.

Which parts are missing on your broken pen?

The diagram is very helpful Francis, thank you!

You're welcoma Hari !

Just added a picture of the barrel end, showing the filler more detailed.

Very useful drawings Francis, Thank you !

Francis it is showing there being a screw (#4) attached to the nut (#3). On mine it wasn't a screw but a shaft that was physically attached between the nut and cup/saucer that holds the pressure bar. For the life of me I cannot understand how it was assembled. Before crumbling away the entire assembly resembled a dumbbell with the casein button on one end and the cup/saucer on the other end.

Ralf,

Soennecken most probably made small design variations over time

A few questions on th parts shown in your picture if I may :

1) Is the central bore of the little brass cup with screw thread ,meaning is it a nut?

2) Your casein push knob has a stepped outside diameter, and it looks there is a small transversal pin its smaller diameter part .

Is this effectively so?

Thanks !

1) Francis I don't believe the central bore of the cup is threaded. It's just a hole.

2) Yes the casein tapers down as it get closer to the metal. I have no idea how the casein is attached to it. I don't know if it is screwed it, glued in, clamped in.

 

I'll take a closer look when I get home. There was a small brass roll pin. The roll pin was wrapped around the pressure bar. I don't know if the roll pin was part of the pressure bar assembly or the button assembly. It does fit inside of the central bore of the cup.

1) Francis I don't believe the central bore of the cup is threaded. It's just a hole.

That's what I expected, its just cup washer.

I expect the smaller diameter of the casein push knob enters in the cup seat. i

f there effectively is a small transversal pin in the push knob's smaller diameter ,the pin will engage in one of the transversal slots of the cup washer.

in this case the cup washer is simply pushed down by screwing the filling knob on.

Technically not as good as the system on my sketch, the threads In the casein being prone to stripping

2) Yes the casein tapers down as it get closer to the metal. I have no idea how the casein is attached to it. I don't know if it is screwed it, glued in, clamped in.

The casein push knob will most probably have a central tapped hole

 

I'll take a closer look when I get home. Look forward reading on your findings !

There was a small brass roll pin. The roll pin was wrapped around the pressure bar. I don't know if the roll pin was part of the pressure bar assembly or the button assembly. It does fit inside of the central bore of the cup.

The roll pen was certainly part of the pressure bar, no doubt about that

Francis it's weird. The cup side sits in the barrel. There is a small hole for the post at the bottom of the barrel. Then the collar reverse screws into the bottom of the barrel. There is also a matching small hole at the top of the collar for the post. I'm going to take pictures.

Thanks markiv , much appreciated !

This confirms the design shown on my sketch .

Only difference - as seen on Raif's picture - being the barrel also features a smaller hole ensuring a wider back-up surface against the large collar of the brass screw .

I have one perfect Rheingold in my collection, but could not unscrew the brass nut to get it completely disassembled. Since the pen is in perfect condition I've refrained to go further ,avoiding the risk of damaging the pen .

Hi

 

Hi Raif,

I've just dissembled the filler of a "Präsident" and now I understand your statement "The metal was so brittle and just crumbled". Surprisingly the screw - item 4 on my sketch - is not made from brass , but from aluminum !

And aluminium is prone to heavy corrosion when exposed to ink.

The best solution is making a replacement screw from brass.

On your picture one can see the threaded part of the screw is still in the knob (1) , and still holds the nut (3) mounted against the knob.

The loose washer is just the remaining flange of the screw (4)

I can make you a replacement screw in brass and make your pen functional again.

Just send me a PM when interested .

Francis I feel a little less stupid knowing the post is aluminum and prone to corrosion. Vik has come through and is saving me. He's sending me some parts. My fingers are crossed that it will work. If not, I will need you, the master fabricator to make the part.

[Raif79]

Update:

 

Vik came through and saved me. I can't thank you enough Vik! The piece was a perfect fit. It was also in significantly better shape than my brittle ruined one. My heart is now beating at a regular pace. The Soennecken is back together and works like a champ. In the future I will be more gentle. In fact I have no intentions of ever taking that piece out again. Francis thank you so much for the research and incredible diagrams.
