Eyedropper - Mabie Todd & Bard, Ink Flow


Recommended Posts

Sharing some photographs of a 1902 Mabie Todd & Bard silver eyedropper with the ink flow control valve.

As per the book, of Steve Hull, the ink control valve is illustrated below.

I'm not sure that it is more of a marketing claim than a precision ink flow control!

Anyone had good experience of using this ink control stopper?

NB. The BCHR slip cap is not original, i'm sure looking at advertising of the time it would have been silver overlay.

That's a lovely example.

 

I had one with that system with the two long wires inside the barrel.

 

I understood that the plug was to fill the pen without unscrewing the section and I believe that MT produced special bottles for the purpose.

Thanks Cob,

 

Yes it was patented, by Stewart, as an alternative filling point but also a claimed precise flow control valve. (Hull and Moak)

 

Whilst there is a constant ink flow path along the top of the feed, pulling the plug out a little way opened another flow

path to the channel on top of the feed.

 

This claimed to enable setting of the ink flow rate to suit the pressure and speed of the writer.

 

I've tried a few different positions of the plug but doesn't seem to make a difference.

 

I'll try some alternative inks.

 

Cheers Kevin

Based on the pictures, you might never have the plug in far enough to increase flow. I would also make sure that the nib is in good contact with the feed all the way to the end of the feed. Although, I actually have not found the plug to matter as much as the overall cleanliness and relative position of the nib and feed.

I've had one of these plug fillers too. It's a good filling system but a means of adjusting the flow? Just a piece of advertising hogwash.

Eachan

      @Texas42 Thank you. I myself have recently had the experience of cleaning out a Wing Sung 699, in which the iron-gall ink has been sitting for six months. No damage to the metal piston rod (whereas, in a Wing Sung 3013 vacuum-filler, it would have been corroded, turned green, and contaminated the ink in mere weeks), but there was a ring of colour at the far end of the barrel that wouldn't budge, and I found it impossible to unscrew the filling mechanism to clean the interior wall of the ink rese

      Dang. You are a great friend!   One comment as a relative newcomer would be within the cleaning section: issues/differences in cleaning vacuum filler, piston filler in addition to cartridge/converter. I just cleaned out my Pilot 823 and while it wasn't particularly difficult I was a little paranoid about the drops of water that I could not get out. Perhaps this is something you are already including.   Anyway, great project and very thoughtful of you. I know it's a project fo

      Ah Ruaidhri ya wee heid banger, you do indeed have an Irishman’s way wid dose words now. I’ll be from outer Aberdeenshire up in the blizzard riven braes of the Grampians.  Amateur medicine and surgery is it? Well what noble aspirations you do possess, we need to encourage such noble experimentations.  I pondered on leaving my own battered shell to science, but, until I read your pearls of wisdom and lament, I had comedown on the side of leaving my body to Findus frozen foods.  However, your rema

      Hi Smug Dill,   Nice project.  If it were me, I'd cover stuff like: - nib types available, i.e. styles, materials (SS vs gold), flex vs nails; - filling systems (I love the "thingie" comment) and how once can use them in practice (e.g. fill cartridges with a syringe); - pen body materials and their consequences (pen not balanced of too heavy and big for the hand); - and, whilst you've made it clear that you do not like vintage pens, a discussion of these beyond "I d

      Thanks for your input! Yes, not putting wood in the list of body materials warranting a mention was an oversight. I love pens with wooden bodies, but my main concern, or chagrin, is that I have not come across a wooden-bodied pen with a wooden cap that seals well. Actually, there is one, but it isn't really wood per se: the Pilot Custom Kaede's maple body is resin impregnated. All other wooden pens I have can dry out while capped and undisturbed; that includes several Platinum #3776 models.
