Patent for a new and improved planter. This design "has relation to that class of cotton and corn planters in which are hoppers smaller at their top than at their bottom and hoppers larger at their top than at their bottom, to adapt them for planting cotton-seed and corn, respectively. It is the object of the invention to provide the planter with interchangeable hoppers of the above construction, whereby either can be used upon the same machine, as found desirable, the hopper-seat being especially adapted to receive and hold thereon either one of the hoppers" (lines 12-24).
