16,283. Widder, V. July 14, 1910, [Convention date]. Cultivators.-A spring tooth for cultivators is provided with an auxiliary spring b connected to it at its lower end and engaging at its upper end under a rearward extension of the main spring a and against a fixed abutment c. When the tool e encounters an obstruction, the spring b bends until it becomes disengaged from the abutment c, thus allowing the tooth to yield. It returns to its original position when the obstruction is passed.
