  • Patent number: 10918245
    Abstract: A coffee grinder-doser includes a grinder-doser body enclosing a grinding chamber which houses first and second mills configured and mutually positioned to grind coffee beans into powder. An external ring-nut which is gripped and rotated by an operator integrally connects to the first mill. A nut screw with a longitudinal axis, inside the grinding chamber, is engaged with an external thread of the ring-nut to translate the first mill along the longitudinal axis. The ring-nut includes a ring-nut body and indices defining the angular position thereof. The grinder-doser body includes a fixed reference for the indices. The ring-nut is associated with a graduated ring having the indices, and a cover at least partially removable to lock the graduated ring between the cover and the ring-nut. The cover is fixed to the ring-nut body by a partially removable couple for adjusting and locking the angular position of the graduated ring.

  • Patent number: 10240969
    Abstract: A device with weighing capability (or “scale feature”) and also anvil capability (or “tapping feature”) allows accurate and precise filling of an espresso portafilter with coffee grounds for use in beverage preparation. Some versions switch between a protected mode for anvil use, and a weighing mode for accurate weighing of the portafilter and its grounds, by pivoting the entire load cell into and out of a protected location wherein tapping/shocks do not flex/strain the load cell free end. In other versions, one or more stop(s)/limit(s) are near the load cell free end or associated elements, and the free end/elements move during said tapping/shocks but only to the stop(s)/limit(s), corresponding to a safe amount of strain for the load cell. Also, this way, weighing the portafilter and its contents may continue between taps without switching to a separate protected mode.
