of the disclosure A manually operated appliance, particularly adapted for a two-component substance double dispensing cartridge, features two rams between which a thrust member is disposed in cylindrical sliding guides. Pivotably attached to the thrust member are ratchets, the pawls of which engage with an indentation extending on either side of each ram in order to move the rams including thrust pieces in the direction of the cartridges. A thus guided thrust member, which is essentially movable only in parallel to the rams, provides for perfect force transmission and exact proportioning even when relatively great pressures occur and different diameters of the individual component cartridges are used.
