  • Patent number: 5197372
    Abstract: A device for preparing hot beverages such as coffee by extraction having an extraction cup (5) movable from an outset position to an extraction position along a control track (2) in a mounting plate (1) by a movable holder (4). The extraction cup (5) is detachably secured to the movable holder (4). The extraction cup (5) is filled from a coffee grinding unit (3) and is then displaced along the horizontal portion (2') of the control track (2) laterally until it is located vertically below an extraction piston (11), whereupon it moves vertically upward. In this manner, the ground coffee is compressed. Simultaneously, through a hot water inlet neck (8), communication with a hot water heater (10) is established. After the extraction, a stop (15) is displaced beneath a tappet (7) supported in the extraction cup (5) and keeps the tappet at the top of the extraction cup (5) during the downward motion of the extraction cup (5).
