Mechanisms Used In A Pen

In the early years the reservoirs are filled with ink using an eyedropper, but it is a messy process, but the advantage of pen is that it can hold more ink than any other auto filling a pen. The next generation self-fillers used which is composed of rubber containing ink sacs. The runway is squeezed and released to fill the ink. In the year 1901 Conklin crescent filler was introduced to the public, this is the first mass production of self-filling pen.

The mechanism used in Cresent filling pen: it is a crescent-shaped arch fixed strong metal bar pressure, the crescent section jetting out from the container by a pressure bar and slot placed in the barrel . The second part has a semi circular hard rubber ring situated between the barrel and crescent. The ring is used to block the somewhat circular ring from pushing down. To refill the pen user has to just turn the ring around the barrel to the C-shaped ring corresponds to the space inside the ring. This allows it to push down the crescent and the inner sac compression.
In the year 1950 a new plastic ink cartridge is introduced. Early in the 1820s filler screw-piston mechanism came into being. The system has been widely used only when the Pelican was introduced in 1929. The basic mechanism used by a simple touch the bottom of the pen and a piston is drawn up in barrel by a screw mechanism, which helps milk the ink. In the year 1949 to touch down filler is manufactured by Sheaffer, it has a handle under the barrel that can be removed and the plunger can be pulled out to full length. The tip of the pen is less ink container, the plunger that pushed compresses and then releases the ink cartridge for pressure sir.
