ABSTRACT:
An apparatus for assembling the components of a trophy includes a socket for engaging a nut employed to connect the components, a bidirectional motor coupled to the socket, a clutch mechanism coupling the bidirectional motor to the socket, a spring retained between the motor and the socket to allow axial movement of the socket relative to the motor, and a bracket for adjustably mounting the motor, clutch mechanism, and spring beneath a work surface for supporting the components of the trophy. The socket is biased upward by the spring so that it projects above the working surface. The motor is operable in a first direction to tighten the nut and in a second direction to loosen the nut. The clutch mechanism provides a torque-limited connection between the motor and the socket in the first direction to prevent excessive tightening of the nut and a positive connection in the second direction to loosen the nut.
