Named for its typeBAR-LOCKing mechanism, the Bar-Lock also featured a full, double keyboard and a front-downstrike typebar arrangement. It was produced by the Columbia Type-Writer Manufacturing Company of New York, NY, ca.1889, and invented by Charles Spiro. This Bar-Lock's most stunning feature was its ornate, cast iron shield that stood upright behind the keyboard. The shield did double duty. It protected the typebars as well as offered them something firm to rest against. As the models progressed for this brand the shield became less and less ornate and the full keyboad was eventually phased out.
