Typewriter with improved case shift means

A typewriter having a body, a typebar assembly and a carriage which is movable vertically relative to the typebar assembly to enable the carriage to take up one of three positions to provide three cases of type, in which the carriage rests on a single shift member slidable vertically in guides formed in the typewriter body, and there is provided biasing means acting between the typewriter body and the shift member and biasing the shift member upwardly with a force sufficient to overcome the weight of the carriage acting on the shift member, stop means preventing upward movement of the shift member by the biasing means beyond an intermediate position, a first shift key linked to the shift member so that actuation of the first shift key lifts the shift member and carriage beyond the intermediate position to an uppermost position, and a second shift key linked to the shift member so that actuation of the second shift key moves the shift member and carriage downwards against the bias of the biasing means to a lowermost position, the lowermost, intermediate and uppermost positions of the carriage corresponding to the said three cases of type.
