Abstract

An electrically operated knife includes a handle and a first set of dual cutting blades connected together for reciprocal side-to-side linear motion. A first stationary motor connected to a power source and a first reciprocating assembly is removably connected to the first set of dual cutting blades and coupled to an output shaft of the first motor for reciprocally moving the first set of dual cutting blades. There is a second set of dual cutting blades mounted in spaced relationship to the first set of dual cutting blades. A second motor and a second reciprocating assembly are provided for reciprocally moving the second set of dual cutting blades. A mounting member and a pivotable lever are provided for selectively adjusting a spaced relationship between the first set of dual cutting blades and the second set of dual cutting blades and a switch which operates both motors.

Dependent claims

An electrically operated hand-held knife, said knife comprising:

(a) a handle;
(b) a first set of dual cutting blades connected together for reciprocal side-to-side linear motion;
(c) a first electric motor mounted within said handle and connected to a power source;
(d) a first reciprocating means removably connected to said first set of dual cutting blades and coupled to an output shaft of said first electric motor for reciprocally moving said first set of dual cutting blades;
(e) a second set of dual cutting blades connected together for reciprocal side-to-side linear motion and mounted in spaced relationship to said first set of dual cutting blades;
(f) a second electric motor mounted for lateral movement within said handle and connected to said power source;
(g) a second reciprocating means removably connected to said second set of dual cutting blades and coupled to an output shaft of said second electric motor for reciprocally moving said second set of dual cutting blades;
(h) a mounting means for enabling said lateral movement of said second electric motor, said second reciprocating means and said second set of dual cutting blades;
(i) a manually operable means for laterally moving said second electric motor, said second reciprocating means and said second set of dual cutting blades and for selectively adjusting said spaced relationship between said first set of dual cutting blades and said second set of dual cutting blades;
and
(j) a switch disposed in said handle for operating said first electric motor and said second electric motor.
