Abstract: A bench holder for a clock mechanism under repair. The holder comprises a pair of parallel-disposed, clock-mechanism, platelike holding jaws. A jaw support rod is rigidly fixed to one jaw and projects therefrom. A pair of manual adjusting screws adjustably supports the second jaw on the first jaw for a parallel opening and closing movement of the jaws. A first bench top support stand has an elongated shaft formed at one end with a first socket receiving hole. A clamping collar is adjustably fixed to the end of the shaft having the first socket hole. The collar and the shaft are each formed with aligned holes on an axis normal to the longitudinal axis of the first socket hole. The jaws may be optionally inserted into either the first socket hole in the shaft or in the aligned socket holes and rotated within each of the socket holes to effect a desired attitude of the clock mechanism. In the first bench top support stand, the shaft is telescopically received by a tube supported on a base.
