Abstract
609.989. Manure and like distributers. ABBEY, A. (Aktiebolaget Westerasmaskiner). March 27, 1946. No. 9491. [Classes C(i) and 58] Relates to seed-sowing machines of the type having a hopper 1 at the base of which delivery rollers 3 feed seed to coulters 21. For determining the rate of sowing, such machines are sometimes provided with a sampling pan 14 which can be swung into or out of operation, the pan being adapted to co-operate with doors in the hopper which deflect the seed away from the drills and into the pan when the latter is in its operating position.- According to the invention, the doors 5 are all connected to a shaft 12 which is engaged by members on pivoted arms 15 by which the sampling pan is mounted on the hopper. In the form shown, rollers 3 expel seed from the hopper 1 over its bottom edge 5' to fall through a seed run 2 into coulters 21. A plurality of bottom doors 10, one to each roller 3, are pivoted to the seed run and are all connected to a shaft 12. The sampling pan 14 is mounted on pivoted arms 15 formed with members 17, 18, which engage the shaft 12 and cause the doors to swing about their pivots 11, when the pan is moved into its operative position (shown dotted), the seed being then deflected into the pan. When it is desired to empty the hopper the hopper bottom 5 can also be swung down by means of a lever 7 to allow the contents of the hopper to fall into the pan. A catch 24 normally retains the pan in a raised position.
