Abstract
A discharge chute unit is provided for attachment to a coffee grinder which has a discharge opening in the underside of a grinding chamber. The upper end of the discharge chute unit is mounted under the discharge opening and provided with de-chaffing the de-plugging means. A baffle is pivotally mounted in the upper end of the chute unit below the de-chaffer and de-plugger and normally biased in a position to deflect the flow of ground coffee and chaff toward the back side or rear wall of the chute member. The free discharge of chaff into the chute unit is prevented by a de-chaffer having reed-like de-chaffing members which yieldably obstruct the inlet opening into the chute unit without overly interfering with the discharge and flow of ground coffee from the grinding chamber into the chute unit. The pivotally mounted baffle carries on a support rod one element for depressing the reed-like members so as to provide a de-plugging opening and another element which is located in the discharge opening of the grinding chamber for knocking or breaking up ground coffee that has become lodged and caked in the opening. Manual pivoting of the baffle actuates both the element which depresses the de-chaffer reeds and the de-plugging or knockout bar.
