Thompson's Seeding Machine
One of the earliest hand seeders, patented by Joseph Thompson, of Durhamville, NY, Jan 13, 1857. A grooved roller is rotated by a rack gear on the handle, to distribute a seed to each of 5 tubes, where it is pressed into the ground by a punch in each tube. A spring loaded plate rides up and down the seed tubes, allowing the punches and tubes to be withdrawn from wet soil without sticking. Adjustment can be made for various seed sizes, including beans and gourd-seed corn. The hopper cover and another cover over the roller are missing and the mechanism is worn and no longer operates smoothly. Still, a quite early example of mechanized planting.
