Jeff Joslin Vintage Machinery entry for H. B. Smith Machine Co.
|
Description: |
This patent depicts a single-end tenoner. Two such mechanisms were used on the #2 tenoning machine from H. B. Smith Machine Co., which was probably the very first double-end tenoner, introduced in 1876 (apparently Smith started work on the double-end design in 1866 but it took a decade to work out the bugs). A reported example was used in a window factory until the late 1990s."The present invention consists in so arranging the cutter-heads of a wood-tenoning machine that while they can be adjusted with regard to each other to any thickness of tenon, they can be after such adjustment brought to any position with regard to the end of the board or plank upon which they are to operate." |
