Snapfil Restoration

[Univer]

Hi All,

 

I'm planning to resac a Snapfil in the near future, and I'm wondering if there are any specific concerns I need to be aware of. I've seen Internet posts suggesting that the section is a tight friction fit, so I'll proceed on that basis; but are there special issues arising in connection with the proprietary filling mechanism? (The only "reverse" lever I've worked on is an Eisenstadt, and that was a breeze.)

 

On a related matter: is there a patent covering the Snapfil lever system? I wasn't able to find one, but I readily admit that I'm not the world's most proficient patent searcher. I would love to have the patent drawings available for reference.

 

Thanks for your help!

Hi Jon;

 

Some of these are screwed in sections, some are just friction fit. I've collected them for 20 years plus, and they made all sorts of varieties.

Hi Steve,

 

Thanks for the reply! I eventually decided to have a go at the pen, and I'm pleased to report that all went well. It turns out that the section in my pen (a #2 nib) was a friction fit. The customary rocking motion didn't work in this case; ultimately, after application of a fair amount of heat, the section came out nicely with a twisting motion. The remainder of the restoration was, thankfully, uneventful.

 

You must have a wonderful collection, and I certainly understand the attraction of these pens. The lever mechanism, as others have observed, might actually have a legitimate claim to being an improvement over the conventional arrangement.

 

Now all I need is a replacement lyre for the end of the chain....

 

Cheers,

 

Jon
