Abstract

THE DEVICE DISCLOSED HEREIN IS PORTABLE, POWER OPERATED TOOL FOR TRIMMING HEDGES, SHRUBS AND THE LIKE AND INCLUDES A HOUSING ADAPTED TO HAVE AN ELECTRIC MOTOR SUPPORTED THEREIN. POWER FOR THE MOTOR IS SUPPLIED BY A SOURCE SUCH AS A BATTERY SUPPORTED ON THE HOUSING, AND A HANDLE ON THE HOUSING FACILITATES EASY MANIPULATION AND CONTROL. A STATIONARY, DOUBLE-EDGED, TOOTHED COMB IS FIXED TO THE HOUSING AND THE MOTOR IS ADAPTED TO RECIPROCATE A DOUBLE EDGED, TOOTHED BLADE DISPOSED IN OVERLAYING RELATION WITH THE COMB. THE TEETH OF THE BLADE HAVE A NOVEL CONFIGURATION CALCULATED TO ENHANCE CUTTING EFFICIENCY AND IMPROVE FEEDING CHARACTERISTICS WHILE MINIMIZING POWER REQUIREMENTS OF THE MOTOR AND/OR POWER SOURCE.
