Grinding mill for coffee beans and the like
First Claim
1. A grinding mill for coffee beans and like articles comprising a receiver including a bottom wall and peripheral side wall for receiving articles to be ground, said bottom wall having a plurality of passageways each sized for successively and gravitationally passing articles to be ground, a discharge member beneath and rotatably connected to said receiver and having a discharge opening communicating with said passageways for receiving material therefrom, and grinding means interposed between said passageways and discharge opening for grinding articles and passing granular material to said discharge opening, obstructing means on said discharge member generally between said grinding means and said plurality of passageways for rotation with said discharge member into and out of obstructing relation with said passageways, said obstructing means being configurated to simultaneously obstruct certain of said passageways and open other of said passageways, to thereby limit the number of coffee beans and like articles which can be ground at any given time by said grinding means.

- 10. A grinding mill for coffee beans and like articles comprising a receiver including a bottom wall and peripheral side wall for receiving articles to be ground, said bottom wall having a plurality of passageways arranged in a generally circular array concentric with the axis of rotation of a discharge member for gravitationally passing articles to be ground, said discharge member being beneath and rotatably connected to said receiver and having a discharge opening communicating with said passageways for receiving material therefrom, and grinding means interposed between said passageways and discharge opening for grinding articles and passing granular material to said discharge opening, said grinding means being in circular concentricity with said axis and facing upwardly into said passageways, and obstructing means on said discharge member generally between said grinding means and said plurality of passageways for rotation with said discharge member into and out of obstructing relation with said passageways, said obstructing means being configurated to simultaneously obstruct certain of said passageways and open other of said passageways, to thereby limit the number of coffee beans and like articles which can be ground at any given time by said grinding means.
