Mechanisms used in a pen In the early years of the ink tanks were filled with a dropper, but this was a difficult process, but the advantage of this pen is that it could hold more ink than other filling automatic pen. The next generation used loads itself that were made of rubber bags to hold the ink. The bag is pressed and released to fill in the ink. In the year 1901 to fill Crescent Conklin was presented to the public, it was the mass production of self filling pens.
The mechanism used in Cresent filling pens : it has an arc-shaped crescent fixed to the metal under high pressure bar, the Crescent section of jet from the door by a pressure bar and the slot in the barrel. The second component has a semi-circular ring of hard rubber between the barrel and the Red Crescent. The ring is used to block the ring semi-circular push downwards. To charge the pen, the user simply turn the ring around the barrel until the C-shaped ring is the difference inside the ring. This allows him to push down the crescent and compress the inner bag.
In the year 1950, a new toner cartridge plastic was introduced. By the early 1820s to fill screw plunger mechanism came into force. This system has been widely used only when the Pelican was introduced in 1929. The basic mechanism used a single key at the bottom of the nib and a piston is drawn to the barrel by a screw mechanism, which helps to suck the ink. In the year 1949 the touchdown filler was manufactured by Sheaffer, it has a handle at the bottom of the barrel, which can be removed and the piston can be purchased for entire length. The tip of the pen has fallen into the ink container, the plunger is pushed into the compresses and then releases the ink sac because of the pressure sir.
