Concave curve-shaped stem capturing recesses are provided in edges of stem guiding slots in non-blade carrying member of a rechargeable, battery powered reciprocating hedge and shrub trimmer. The recesses have portions presenting acute stem contact angles to the guided stems, which portions extend inward from about the location of the blade tip a distance greater than about 50% of the effective blade height.

Reciprocating trimming apparatus

A workpiece supporting and clamping assembly is adapted to be mounted on a wall or similar structure and to be adjustable between a substantially vertical storage position, closely adjacent the wall and a working position substantially perpendicular to the wall. The assembly comprises a pair of brackets, a pair of spaced apart, parallel hinge assemblies, each having locking means and a release lever associated therewith, and a workpiece supporting and clamping device, pivotally coupled with the brackets and hinge assemblies. The workpiece supporting and clamping device comprises a generally rigid base frame which includes a pair of parallel, spaced apart frame members and a pair of elongated, coplanar top members which are mounted on the spaced apart members, extending generally transversely thereto such that their upper surfaces define the work supporting surface and their opposed side surfaces, the work clamping surfaces. The supporting and clamping structure is pivotally mounted, to the brackets and to the hinge assemblies, which are pivotally interconnected with the brackets. When the workpiece supporting and clamping assembly is in its storage position, the hinge assemblies are collapsed. When the assembly is brought to its working position, the hinge assemblies are extended and lock securely in extended position supporting the supporting and clamping structure and in its working position until both hinge assemblies are affirmatively released by means of their respective release levers.

Workpiece support and clamping assembly

An improved arrangement for mounting an auxiliary workpiece support body to a workpiece support device includes a restraining means for selectively inhibiting and enabling motion of the auxiliary support body in the direction of a longitudinal axis while simultaneously enabling rotation of the body about the axis. The auxiliary support body includes a means for restraining jaw cladding bodies of different thicknesses on a workpiece support device and permitting rotary motion of the support body.
