Picture 3-2-1 The Illustration of Fountain Pens : Li Wen Lu

 

 

　　From the above picture, we know that usually a fountain pen consists of a cap, holding parts, shaft, ink-filling mechanism. Holding parts include pen tip and pen tongus. The parts of structure are in Table 3-2-1 as follows.

 

　　　Table 3-2-1 Names, functions, and features of Fountain Pen Parts

Structures	Functions and Features
Pen Cap	To protect the fragile tip to avoid external impact. To prevent the ink from evaporating and drying. Common ways to fix. Lock with threads . Clamp with elastic reeds. Attach with latches. Attach with magnets.
Clip	Located on the pen cap. Used to hold the pen onto the pocket.
Nib	Iridium Point A small spherical platinum-iridium welded on the point of nib and paper is often called "iridium point." The size of iridium point determines the thickness of the pen width. Slit Connected to the rear Iridium point. Use capillary action to make ink stabilize joints increase. Vent Connected to the ends of the gap. Facilitate air flow equilibrium pressure. Avoid occurrence of stress concentration to make nib slit split.
Pen Tongue	Steadily and smoothly send the ink from the ink sac (or cartridge) to the tip. As a tip fixed base. 3 parts : Ink Road : Use capillarity to continue feeding the ink to the nib. Ink fins : Store excess ink from when pressure changes, making the continuous ink supply stable when writing. Airway : Used  balance the air pressure inside and outside the ink sac, so that a continuous supply of ink to the ink sac nib and ink flow in Sheung Shui as a pipe.
Holding position	The components covered with Tubular material and fixes pen tongue and pen nib are called grips. Has a close relationship with comfort. The grip friction, hardness, size, shape of the holding position has a close tie with of comfort.
Pen	Connection grips ink reservoir devices coated tubular member to become pen. Has a general size and short game of the points.
Sheung Shui / ink storage mechanism	Dropping The ink storage is behind the pen tube. When refill, unscrew supplement ink dropper directly in the grip, and then inject the ink into the pen tube. 　 Ink Cartridge Ink is packaged in a sealed ink tube. Put it on the rear of the grip when using. Use the    ink tube on the rear of the grip to puncture ink tube seal, or top open closed ink for the ink tube beads to flow along the ink tube tip. Advantage is that the ink volume, the disadvantage is easy to penetrate the ink pollution. 　 Piston ink Connect the rear grip a bit hollow sleeve, the sleeve has a piston linked to the pen at the end of the knob, when the piston is retracted inside the sleeve to facilitate the formation of negative pressure, can be inhaled through the ink pen and stored in the sleeve. 　 Ink absorber Ink Cartridge can be regarded as the ink tube and the piston or pressure on the ink sac complex, in front of the grip combined with the cartridge, press the rear of the ink sac or piston mechanism only, do not remove the ink absorber is also Dress ink cartridge same specification pipe. 　 Pressure on the ink sac Rear of the grip a rubber or silicone material connecting the ink sac, ink is the ink sac inside the space, usually outside of the ink sac will have a U-shaped spring to protect the ink sac, when the ink on the ink sac squeeze through the reed exhaust air, relieve the pressure after the use of the ink sac restore the original shape of the vacuum suction ink. 　 Rod inking Pressure capsule is a variation of the ink. Installation of a lever on the pen when you flip the lever on the oppression of the ink pen ink on the inside of the ink sac. 　 Crescent inking Pressure is also a variation of the ink bag. Installation of an arc on the pen <crescent> button and, usually flat on the barrel of the pen with curved tabs across the arc gap between the buttons, to prevent inadvertently inking mechanism, remove the card when the ink on the mortise latch the crescent was less pressure, oppression pen ink on the inside of the ink sac. 　 Coin Inking Pressure is also a variation of the ink bag. In a long hole opened on the pen, the ink will be inserted into the coin slot to oppression pen ink on the inside of the ink sac.
