Patent for a new and improved cultivator. This design "is to produce . . . cultivators [that] can be adjusted laterally in relation to each other and turned at any desirable angle, and in which the frame and the beam can be made to stand at any desired angle to each other" (lines 17-23). It consists in "a semicircular frame, two vertical plates secured to the ends of the said frame and having their upper edges serrated, blocks placed between the plates, the plates, bolts for clamping them to opposite edges of the vertical plates, and the cultivators which pass through the plates and the beam" (lines 8-15).
