Abstract
A dispensing tool according to the present invention includes a dispensing outlet and at least a first material storage tube having a material storage chamber and an outlet. The tool also includes a drive assembly that is at least partially disposed within the first material storage tube and adapted to dispense material from the first material storage tube through the dispensing outlet. A valve assembly selectively controls the flow of material from the material storage tube to the dispensing outlet. The valve assembly and the drive assembly are linked such that activation of the drive assembly causes the valve to open allowing material to be dispensed. When the drive assembly is stopped, the valve is automatically closed. Material may be reloaded into the material storage tube through an inlet that is selectively connected to a source of bulk material. The selective connection may be provided by a controllable valve, or a selective connection between a pair of coupling elements. Indicators are provided to tell the user when the tool is full and to turn off the pumps for the bulk material when the connection between the couplings is broken.
