Filling System Of The "standard" Pen?

[Cepasaccus]

At the moment I do get always "Error This upload failed" even with files <90kB. Don't know why. But because of this, I can show you the ad only via a neighbor forum. It is the third ad in that thread:

http://www.penexchange.de/forum_neu/viewtopic.php?f=18&t=12822

 

This ad is from 1905 from a New York newspaper.

 

"IT FILLS ITSELF; IT CLEANS ITSELF automatically.

No ink dropper.

No stained fingers.

No over-flew. Can't fill too full.

No hump or projections.

No valves or pistons to leak.

No extra parts - no extra costs.

No openings of any kind in barrel.

SIMPLICITY ITSELF."

 

"Fills itself instantly at any ink-well, THIS WAY."

Showing a hand holding a pen into an ink-well.

 

The only filling mechanism which comes to the mind is capillary, but 1905 would be quite early for that and "IT CLEANS ITSELF" does not really fit. Any ideas or better knowledge about the filling mechanism of this pen?

Squeeze-filler (barrel splits).

That would be the William Bolles "Standard".

The barrel doesn't so much split as simply unscrews.

The advertisement does not really give the impression of an eyedropper.

 

Daniel, is this knowledge or guess?

Not sure what you mean; I didn't say it was a dropper filler. It has a sac and a squeeze mechanism that are exposed when the barrel is unscrewed.

The eyedropper comment was in response to David.

 

Do you know that it was a squeeze filler or do you just guess?

David didn't say it was a dropper-filler, either. He clarified my description by pointing out that the barrel unscrews (as contrasted with a squeeze filler that has a barrel that pulls apart generally in its middle).

 

I don't guess, and I'm confident that David Nishimura doesn't, either.

Then I misunderstood David.

 

Thanks.

I'll see if I can find you a picture of the interior of a Bolles. I had one in my catalog a while ago with the original sac perfectly petrified.

A little too busy at work today, but you can look up US patent 737,697 to see the arrangement.

Special sac with integral pressure bars on either side.

Thanks.

I restored one once, using two sacs (one slipped over the other) and the original two pressure bars, sandwiched in between.

Here are some photos of three Bolles pens I own. Notice that each nipple is different. The small mottled pen has what appears to be the original sac. In raised letters on one side there is "Pat. Sept. 03.05." and on the other side "No. 09." It looks like there may be two bars fused to the inside of the sac, but I don't want to risk breaking the sac to find out more.

Thanks!

You're most welcome. Do note, however, that these three all require the removal of the threaded section before filling--including the black one, which has a slip cap, and is likely earlier than the other two.
