Universal tool for twin cartridge material systems

摘要

The disclosed universal tool has a front plate with an open ended slot extended from near the front wall center, with the front wall defining the slot having one thickness and the wall spaced from the slot having a greater thickness. The front wall further can be mounted in the tool in two different arrangements, respectively flipped over 180 degrees. This tool thereby accommodates different paired material cartridges, both as to size to give different component ratios and as to constructions, such as from different manufactures. The cartridges further can be shifted along the slot as needed to remain parallel to the plunger rods that drive plungers through the cartridges to cause material discharge therefrom. The stable front wall-cartridge cooperation also holds the cartridge and easily allows rearward plunger withdrawl from the emptied cartridge. Also, centered and offset plunger mounts are provided for the plunger rods to allow different cartridges to fit and work in the tool, without changing the center spacing of the plunger rods.
