A fountain pen is a special kind of pen. It has a metal tip called a nib and a place inside to hold ink, called a reservoir.

The pen moves ink from its reservoir to the nib. It uses a mix of gravity and something called capillary action. This is how liquids move in narrow spaces, like how water goes up a plant stem.

You can fill the ink reservoir in a few ways. Sometimes, you use a small dropper or a syringe. But usually, fountain pens have a built-in way to suck ink up. This can be a piston or a vacuum system. Some pens even use small, pre-filled ink cartridges that you can just pop in.

What is a Fountain Pen Nib?

The nib is the part of the fountain pen that touches the paper. It's where the ink comes out. Early nibs were made of gold with a tiny piece of ruby on the tip to make them last longer.

Since the 1830s, nibs have used tough metal alloys like iridium. Today, most nibs are made from stainless steel or gold. Gold nibs are often 14 carat (58.3% gold) or 18 carat (75% gold). The goal is for the nib to be a bit flexible but also very strong. The tip needs to be super hard so it doesn't wear out easily.

How Fountain Pens Hold Ink

For a long time, until the early 1900s, fountain pens stored ink right inside their main body, called the barrel. These barrels were usually made of hard rubber, often in black or red.

To fill these pens, you had to take off the nib section. Then you would use an eyedropper to put ink directly into the barrel. After filling, you'd put the nib section back on. This process could be a bit messy and needed a quiet place.

The Lever Filler Invention

In 1907, a man named Walter A. Sheaffer came up with a new idea: the lever filler. This design had a small lever built into the pen's barrel. When you pressed this lever, it squeezed a rubber sac inside the pen. This created a vacuum, which sucked ink directly into the pen through the nib. You didn't have to take the pen apart anymore!

This new way of filling pens became very popular after 1912. Other pen companies quickly copied the idea. Parker, another big pen maker, introduced the button filler. This worked similarly but used a hidden button. Many companies used a lever that lay flat along the barrel. The rubber sac inside was the key to these new, easier-to-fill pens. Some pens even used a screw mechanism at the top to squeeze the sac, which made them look very sleek.
