ABSTRACT:
A cordless adhesive dispensing system includes an electrically-heated dispensing gun and cooperating base that supports the gun and effects both a mechanical and electrical connection to the gun. The gun accepts solid adhesive and melts the adhesive in response to an electrical current provided to the gun through a mechanical and electrical interface. The electrical interface includes cooperating electrical contacts on both the gun and the base that effect electrical contact as the gun is mounted to the base by the operator and electrical disconnection as the gun is dismounted. A switch is in-circuit with the contacts and closes the circuit to the gun after the gun is fully mounted to the base and effects electrical interruption as the gun is dismounted. The mechanical interface maintains the mounted gun at a convenient, easy-to-grip attitude and includes pivoted interface surfaces that allow the gun to be pivoted into and out of its mechanical and electrical interfacing with the base in a reliable manner.
