Description:

"I do not claim the application of a string to the tool-carriage in order to lift it; but I claim combining or arranging, as specified, with the tri-armed sectoral lever K and the post or frame of the tool-carriage, two wooden springs L M and a connecting-rod O, and so that one spring may be separated by draught, and the other by pressure, when said lever is forced downward, as explained, the same effecting advantages as set forth."
