Anode Rubber Sac

[bsenn]

Most ossified sacs crumble away. I found one in a senior Duofold (non-lucky curve) which is hard as a rock, but intact. It appears to be imprinted "PARKER ANODE" and "MADE IN USA".

 

Googling the term anode, I came across Parker Service Manual 5115 which mentions "Sac, Anode Rubber".

 

Was Anode Rubber a Parker marketing term, and is it common to find imprinted sacs?

 

BTW, here is the opening paragraph of the service manual:

 

"Repairing a fountain pen is not as simple as it seems. It might be compared to
repairing a watch. It is easy to tinker with a watch with the result that it keeps poor
time or no time at all; and it is easy to tinker with a fountain pen so that it gives the
poorest kind of satisfaction or no satisfaction at all."

Been there, done that... Watches and pens...

Seen these to and never found a suitable answer beyond what you found and stopped looking.

Yes I kept it for a while and found it crumbled one day

Hi,

 

FYI Sheaffer also used this term.

 

I found this sac in a Sheaffer's mid-30's and, as usual, I photographed to have it documented.

 

In this topic also was found another Sheaffer'S Anode into a ebonized pearl of the mid '30:

I think this probably answers your question and it appears to be an eminently suitable method of producing rubber sacs.

Thanks for your info. Here will be the U.S. patent of this process.
