Another noteworthy variant of the system is the one of Carter, derived from a patent (nº US-1209978) of the De Witt-La France, which has a sort of "leash" attached to the lever that prevents it from tipping over once it has reached the vertical position, in order to avoid damage to the pen and the system.
