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. In a second bench side support stand, a C-clamp is modified by welding a collar carrying an adjusting screw to an upper arm of the clamp. The welded collar is formed with a central socket hole which is sized to engage fixedly the shaft when the shaft is manually inserted within the collar. The tightening of the welded collar screw enables the bench side holder to support the jaws at the side of a bench.
In a clock holder having an elongated clock support shaft, the improvement comprising a pair of parallel-disposed, clock-mechanism, platelike holding jaws, a jaw support rod rigidly fixed to one jaw and projecting therefrom, coupling means adjustably supporting the second jaw on the first jaw for a parallel opening and closing movement of the jaws and including a pair of screws with each screw housed within a different jaw to engage receiving threads formed in the opposite jaw, and means serving as a support stand and formed with one or more socket receiving holes to receive the jaw support rod and thereby position the jaws and any clock mechanism clamped thereby at a desired position.
