  • Patent number: 4119242
    Abstract: Apparatus for dispensing seeds individually in a small quantity of water from a suspension of seeds in water, comprises a transfer spool which is housed in a transverse bore which intersects both a chamber and a duct. The spool has a diametral passage and a conduit which connects an orifice with an annular recess. The orifice is formed in the wall of the diametral passage and is of flow restricting dimensions. The annular recess can be placed in communication with a source of liquid pressure or a low pressure reservoir. The seed chamber is filled with a suspension of seeds in water. Water is caused to flow through the seed chamber and past the orifice with the flow being first in one direction and then in the opposite direction while the diametral passage is aligned with the chamber. A seed is captured on the orifice and the suspension of seeds in water is then flushed out of the diametral passage, the recess being in communication with the low pressure reservoir.
