Abstract:
A dispenser for mixing and dispensing a multi-component adhesive or sealant includes a first motor operably coupled to two or more plungers, each plunger being slidably disposed in a respective one of two or more barrels and configured to apply a dispensing pressure to respective materials to be dispensed, a second motor operably coupled to an output drive shaft having a mating end, and a coupling plate removably attached to a front end of the dispenser, the coupling plate configured to attach to a disposable mixer attachment configured to mix and dispense the multi-component adhesive or sealant, the disposable mixer attachment having a drive shaft driving a mixing component and configured to selectively couple with the mating end of the output drive shaft of the second motor, thereby enabling dynamic mixing of the respective materials to be dispensed.

Claim (Index 10):
A dispenser for dispensing a mixture of viscous materials, the dispenser comprising:\n a stock portion defining a handle to enable a user to hold the dispenser by gripping the handle, thereby to operate the dispenser as a hand-held dispenser; a holder portion secured to the stock portion to hold the materials in respective barrels relative to the stock portion; a first electric motor housed by the stock portion; a dispensing mechanism coupled to the first electric motor to dispense the materials from the holder portion; a mixer holder securable to the holder portion to guide the materials from their barrels to a respective outlet port for fluidically coupling to inlet ports of a mixer attachment; and a second electric motor coupled to the mixer by a planetary gearbox and a gear set, when the mixer attachment is attached to the outlet ports, to actuate the mixer attachment; and a controller configured to control the first electric motor as a variable speed motor based on a magnitude of a user input and to control the second electric motor as a fixed speed motor by switching the second motor on a off based on the presence of the user input.
