...that the inventor of the electric motor was a blacksmith named Thomas Davenport? Described as "a brilliantly unsuccessful inventor", Davenport invented the first rotary electric motor. In 1836 he headed out -- on foot -- from his Vermont home to file a patent application at the Patent Office in Washington, D.C. By the time he got there, he had squandered away his money and couldn't afford the $30 filing fee so he turned around and went home. When he later mailed in his application with money he'd raised, the Patent office was destroyed in a fire. He did finally get credit for his invention on Feb. 5, 1837.

Definition

Processes and instruments for inserting in the ground seed, fertilizer, poison, plants, or other material or objects handled in a similar manner. Instruments for planting therefore include means for conveying, dropping, or directing material or objects to or upon the ground, combined with means for preparing the ground, as by furrowing, dribbling, or otherwise loosening or forming cavities therein for the reception of said material or objects, or with means for ridging, hilling, or other wise placing earth over said material or objects, or with both said means.

(1) Note. This class includes, in addition to means for planting or burying certain specificallynamed materials or objects (1) broadcast-planting, comprising means for depositing and spreading material in general uniformly over the surface, together with means operating on the surface (as plows, rollers, harrows) to prepare the surface to receive such uniformly spread material or to cover it or mix it with earth; (2) drilling and dribbling, comprising means having earth-working tools or elements, (as furrow-opener, furrow-closer, hill-marker, cavity-former, etc.), together with means for depositing the material and in most instances means for separating the material from bulk. (2) Note. The terms "pipe or strand" and "liquid or gas" are used in the titles of subclasses herein as typical of a class of materials rather than as limitations. The term "planter element" as used herein includes devices peculiar or necessary to a complete planting operation, the usual elements being an earth-worker, a seed-depositor, and a covering device.

Lines with other classes and within this class

Mechanisms per se for dispensing or retailing material from bulk are classified in appropriate dispensing or material or article handling classes, as for example, Class 221, Article Dispensing, or Class 222, Dispensing; but mechanisms comprising a valved chute to accumulate charges or otherwise peculiarly adapted to insure depositing at intervals, when specialized for use in a planter, are deemed to be planting devices and are classified in this class.
