The L.C. Smith type-writer incorporated some advanced features. As far as we are aware, the No. 2 (actually manufactured before the No. 1) was the first machine that was basket shifted instead of carriage shifted. However, the typing basket shifted up instead of down. The platen was easily removed without tools by moving back a clip over the axle between the platen and the platen knob on both sides of the carriage. This not only allowed replacement of worn-outs platens, but the quick insertion of platens for special purposes, such as manifolding and typing index cards.
