Abstract:
A fountain-pen comprising:a body defining a main reservoir;a nib connected to said body;a supply reservoir in communication with said nib and said main reservoir, said supply reservoir being smaller than said main reservoir;an annular seat in said body arranged between said main reservoir and said supply reservoir, said main reservoir having a widened portion adjacent said annular seat;a valve selectively opening and hermetically closing communication between said supply reservoir and said main reservoir to transfer ink from said main reservoir to said supply reservoir, said valve being a piston type valve which slides along a wall of said main reservoir;a rod extending from said main reservoir outside said body, said rod having a piston end attached to said piston type valve and an opposite end outside said body fixed to an end piece for manually operating said piston type valve so as to fill the pen by means of suction, said piston type valve engaging said annular seat, said piston end of said rod having a sealing disk arranged on a side of said piston type valve adjacent said main reservoir, said piston end having a shaped split shank extending out of an opposite side of said piston type valve from said main reservoir, said piston end including a cone between said sealing disk and said shaped split shank, said piston type valve being movable between said cone and said shaped split shank, said piston type valve and said shaped split shank defining a rod passage between said valve and said rod when said piston type valve is positioned on said shaped split shank, said piston type valve and said shaped split shank closing said rod passage when said piston type valve is positioned on said cone.
