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.

1. A portafilter support and weighing device, for use with a portafilter having a basket and a handle, and with a coffee bean grinder having a grounds outlet, the device comprising: a base for placement at or near the grinder,a portafilter support system upending from the base, anda load cell in the base;wherein the portafilter support system is adapted to hold the portafilter in a generally horizontal position with the basket underneath the grounds outlet of the grinder, andwherein the portafilter support system is mechanically connected to a free end of the load cell so that the portafilter and any portafilter contents weigh down at least a portion of the support system to strain the load cell for weighing said portafilter and any contents;the device further comprising a protection system for preventing excessive movement of the free end of the load cell when the support system is impacted by tapping of the portafilter or other shock,wherein said protection system comprises at least one limit surface provided underneath a portion of the portafilter support system that is adapted to prevent said excessive movement. 2. The device of claim 1, wherein said support system comprises a basket support portion and said at least one limit comprises a rigid and immovable member extending to near a bottom surface of said basket support portion. 3. The device of claim 1, wherein said at least one limit comprises a base surface underneath the free end of the load cell. 4. The device of claim 1, further comprising a connector that connects the support system to the load cell free end, and said at least one limit comprises a base surface underneath said connector. 5. The device of claim 1, wherein said excessive movement is an amount of movement in the range of 10-30 percent more movement than movement of the free end of the load cell caused by the portafilter fully-loaded with espresso coffee grounds. 6. The device of claim 1, wherein the support system comprises a basket support portion and said protection system is adapted to move the basket support portion down against a rigid, immovable arm underneath the basket support portion. 7. The device of claim 6, wherein said basket support portion is connected to the load cell free end by a movable arm, and the protection system is adapted to move said load cell, said moveable arm, and said basket support portion down to a position wherein tapping or other shocks on the basket support portion does not move the load cell further. 8. The device as in claim 7, wherein the load cell is received in a pivotal cradle, and said protection system is adapted to pivot the cradle, which causes the moving of said load cell, moveable arm, and basket support portion down to said position wherein tapping or other shocks on the basket support portion does not move the load cell further. 9. A device as in claim 1, wherein the device is adapted to communicate with the grinder to control the grinder by turning the grinder on and off based on weight readings of the load cell. 10. A device as in claim 1, wherein the device is adapted to communicate with a hand-held digital device adapted to display tare weight and weight of grounds in the portafilter, and is adapted to communicate with the grinder to control the grinder by turning the grinder on and off based on said weight of grounds. 11. A device as in claim 10, wherein the device is adapted to receive at least one input from the hand-held digital device, determined by a barista or management, the at least one input selected from a group consisting of a desired amount of grounds and a desired fineness of the grounds. 12. A portafilter support and weighing device, for use with a coffee bean grinder for espresso beverage, the device comprising: a support system having a portafilter basket support portion and a portafilter handle support portion, wherein the support system is adapted to hold the portafilter in a generally horizontal position with the basket underneath the grounds outlet of the grinder, the support system being connected to a free end of a load cell provided in a base of the device;a stationary arm extending from the base of the device to underneath at least a portion of the basket support portion, wherein an impact on the basket support portion that corresponds to a load greater than weight of a full portafilter pushes the support system and the free end of the load cell downward until a limit is reached that stops said downward movement to prevent damage to the load cell. 13. A device as in claim 12, wherein said limit is said basket support portion abutting down against the stationary arm. 14. A device as in claim 12, wherein said limit is said load cell free end abutting down against a surface of the base. 15. A device as in claim 12, wherein said limit is a connector or other member fixed to said free end and extending below said free end abutting against a surface of the base. 16. A device as in claim 12, wherein said limit is both of the basket support portion abutting against the stationary arm and the load cell free end abutting against a surface of the base. 17. A device as in claim 12, wherein said limit is both of the basket support portion abutting against the stationary arm and a member fixed to said free end and extending below said free end abutting against a surface of the base. 18. A device as in claim 1, wherein the device is adapted to communicate with the grinder to control the grinder by turning the grinder on and off based on weight readings of the load cell. 19. A device as in claim 1, wherein the device is adapted to communicate with a hand-held digital device adapted to display tare weight and weight of grounds in the portafilter, and is adapted to communicate with the grinder to control the grinder by turning the grinder on and off based on said weight of grounds. 20. A device as in claim 10, wherein the device is adapted to receive at least one input from the hand-held digital device, determined by a barista or management, the at least one input selected from a group consisting of a desired amount of grounds and a desired fineness of the grounds. 21. A portafilter support and weighing device, for use with a coffee bean grinder for espresso beverage, the device comprising: a support system having a portafilter basket support portion and a portafilter handle support portion, wherein the support system is adapted to hold the portafilter in a generally horizontal position with the basket underneath the grounds outlet of the grinder, the support system being connected to a free end of a load cell provided in a base of the device;a stationary arm extending from the base of the device to underneath at least a portion of the basket support portion;the device further comprising a cradle pivotally connected to the base and having a rear end to which a fixed end of the load cell is fixed, so that pivoting of the cradle pivots the load cell and moves the support system connected to the load cell free end;a switch adapted to actuate pivoting of the cradle to lower the load cell and the basket support portion so that at least a portion of the basket support portion abuts against the stationary arm, wherein tapping or impact on the basket support portion does not move the basket support portion any further downward and does not move the load cell free end. 22. A device as in claim 21, wherein said cradle is pivoted by a cam system having a cam shaft that pushes on one or more portions of the cradle, and wherein the cam system is operated by a solenoid. 23. A device as in claim 22, wherein the solenoid is actuated by a switch on the portafilter handle support portion, so that resting the portafilter handle on the handle support portion activates the switch to actuate the solenoid.
