Schlesinger Hydraulic Inkstand

The Schlesinger Hydraulic Inkstand, often simply referred to as a “Schlesinger Inkstand,” is a Victorian-era invention, patented in 1842 by Joseph Schlesinger. It’s a unique and somewhat complex inkwell designed to provide a continuous, fresh supply of ink to the pen nib while minimizing evaporation and sediment buildup.

Schlesinger Inkstand Information:

• Central Reservoir: The ink is stored in the central porcelain reservoir.
• Plunger Mechanism: The key to the Schlesinger Inkstand’s operation is the plunger mechanism. This plunger, which moves vertically within the reservoir, is used to control the ink level.
• Rotating Knob and Grooved Slot: The rotating knob on the top of the inkstand is connected to the plunger. The grooved slot on the plunger prevents it from rotating as the knob is turned, ensuring a smooth up-and-down movement.
• Controlled Ink Flow: By adjusting the plunger, the user can raise or lower the ink level in the dipping wells (or fonts). This allows for precise control of the amount of ink available for dipping the pen nib.
• Preventing Spills and Maintaining Supply: The plunger mechanism effectively prevents spills by allowing the user to adjust the ink level to an appropriate height. It also ensures a consistent supply of ink by replenishing the dipping wells as needed.
