Sheaffer Adds A New Filler To Its Line
Sheaffer introduced the plunger fill Vacuum Filling system in 1934, initially on second brands including the "Vacuum-Fil" pen and the WASP line. This sacless filling system used a long syringe-like plunger rod tightly fitted into a cylindrical ink sleeping accommodation that on the downstroke creates a vacuum inside the ink chamber that draws ink into the pen through the feed. Sheaffer adapted this filling system to the Balance line in 1935 and advertised this organization side by side with the proven lever filler. This type of filler was not unique, with Conklin, Wahl Eversharp and numerous second tier manufacturers using similar plunger systems in their pens.

When Sheaffer announced the Triumph line in 1942, the Vacuum Filler and the lever filling systems continued, and remained as choices until 1949 when the Touchdown filler was introduced and replaced the Vacuum Filling system.
How It Works
The Vacuum Filler is actually counterintuitive in its operation. Many people are familiar with how a syringe works. Pull out the plunger and the liquid is drawn into the chamber, push the plunger in and the liquid comes out. Simple enough. The trouble is in what to do near the plunger sticking out of the terminate of the barrel while using the pen. It makes putting the pen in the pocket a bit cumbersome as well.
When the plunger in the Vacuum Fill pen is pushed back into the barrel, this activeness pushes the air inside the ink chamber out, creating a vacuum that chop-chop draws ink through the feed into the ink chamber in the barrel. The vacuum is released to practice this task at the end of the downstroke when the prophylactic plunger piston strikes a deflector at the end of the section, giving a distinct snap feeling and creating a gap for the ink to rush into. A properly working Vacuum Filler will take very smooth and low effort plunger activity and will fill nearly full in a single stroke.

Vacuum Fillers are very unproblematic to apply, and a restored pen will concur a huge amount of ink. Early models typically have "total length visibility" barrels, assuasive for a quick cess of the ink level in the pen. Presently after the introduction of the Triumph line in 1942, Sheaffer stopped making windowed barrel pens, favoring Visulated sections.
How To Fill Your Vacuum Fill Pen
A properly serviced Vacuum Filler pen is a quick and easy filler. The pen needs the entire feed immersed in the ink in order to effectively employ the vacuum to describe only ink into the pen. If non completely in the ink, air will blitz in with the ink and the pen volition not completely fill up. Proficient working Vacuum Fillers can fill up meliorate than 80% full.
Regardless of the illustration in the instructions and Sheaffer'due south advertisements, I strongly recommend using two easily to downstroke the plunger. You actually don't want a lap full of ink if you manage to turn the bottle over considering the plunger sticks a picayune.

Vacuum Fillers flush very thoroughly, but care is needed to avoid damaging the pen and its seals. In a filled pen the plunger has to move through the liquid to extend. The liquid has to go somewhere, and forcing it can create pressure level that will button it through the base of the filler unit and cause leaking out of the butt end of the pen.
Use light force per unit area, ho-hum pulling, and a slight rocking (up and down) motility, to pull the plunger upwards through the filled pen. Then gently push the plunger downward, again in short back and forth strokes until all the liquid united states pushed out.
Don't chop-chop pull the plunger upward and down.
Light pressure, dull pulling, and a slight rocking movement will allow the plunger to correctly release liquid through the department which volition keep the pen operating well and without barrel end leaks.

Vacuum Fillers are smashing pens for those who want large capacity and properly restored pens are very efficient and do not deserve their finicky reputation. Restoration is a professional level job and is essentially more than most other repairs.
