Parker Jotter Spring

[mislav]

At local fairs I always buy Parker Jotter pens if I find them for $1 or less. They are all used and often had refills made by third part companies. What I noticed they also have different springs.

 

Researching on internet I found that Parker today use type of spring as one on the photo. Most of my Jotter pens have it, but some have totally different shapes of springs.

 

Can someone who has old original Jotter springs put here photos of them? Did Parker used always same shape of spring or it was changed during the time?

 

Thank you!

Hi, I have a few, these are as made by Parker, for the years shown.

Thank you Mike!

 

I got one same as "jotter 1970" in pen from 90', but it is possible that someone replace it because pen was used when I bought it.

 

I also have few springs that I doubt Parker made them. I will post photos when I get home.

Very interesting topic. I work for a company that makes springs, and I find it fascinating that they used different designs over the years. From what little I know about the engineering of compression springs, the differences among those springs would not be discernible to the user in the least. One would need a spring testing station to note any difference, and even then I doubt that it would affect the operation of the pen.

 

My own theory is that Parker did not make the springs and that they bought "stock" springs from various companies over the years - wherever they could get a spring that would work at a cost that they found acceptable.

I have just checked all my jotters and they have diffrent type springs. I think SteveE is right suggesting Parker may not have produced the springs and that they may have been buying these from different spring manufacturing companies.

It is possible that Parker did/does not make springs, but I believe if the order it from other company they have some request like shape.

My Jotter pens have springs like those on Mike photos plus those on this photo... All pens I have were produced between 1994 and 2009.
