Description:

This patent covers a mechanism for positioning a machine carriage or slide, especially of a larger machine, which can be controlled from the operator's position and can be positioned to great accuracy using a large vernier scale. This patent is one of a trio granted to Charles B. De Vlieg that were broadly useful across a range of machine tools. All three were assigned to Associated Patents, Inc., a licensing consortium; see the DeVlieg Machine Co. history on VintageMachinery.org (link below patent image).
