Abstract

A manually operable device is provided for dispensing measured amounts of a mastic-like or paste-like multi-component material. The components are supplied in separate containers and each container has an axially displaceable ejection piston. The pistons are displaced by piston rods and each piston rod can be gripped by a clamping jaw and the jaw is displaced via a manually operated lever and a stirrup. A support bearing member affords lateral support for the piston rods and the clamping jaws are pivotally mounted on the bearing member. The drive for the piston rods acts through the clamping jaw and the support bearing member so that each rod is displaced axially and does not need to be connected to the other. Due to a symmetrical arrangement of the forces acting on the support bearing member, the forces cancel one another out.
