| 61 | Electric knife drive mechanism | US689930 | 1985-01-09 | US4631827A | 1986-12-30 | Gregory E. Moores |
| An electric knife having a housing, a motor fixed in the housing having a drive shaft disposed for rotation about a drive axis, a spur gear fixed to the end of the drive shaft, a flange fixed to the motor including an integrally formed, axially-projecting output shaft coaxial to an output axis and parallel to the drive axis, an output gear in meshing engagement with and driven by the spur gear disposed on the output shaft for rotation about the output axis, a tubular element coaxially engaging the output gear for rotation therewith about the output axis, the tubular element including a cylindrical cam in the outside surface thereof, and a pair of blade holders disposed in the housing in adjacent, opposed relation for independent, linear reciprocation parallel to and on opposite sides of the output axis. Each blade holder has a first end for releasably engaging a blade and a second end including a cam follower engaging the cam, the cam followers engaging the cam at positions 180 degrees apart such that rotation of the output gear generates independent, opposite linear reciprocation of the blade holders. | ||||||
| 62 | Three-blade arrangement for electrically powered knife | US42704673 | 1973-12-21 | US3832773A | 1974-09-03 | LANGFORD O |
| An electrically powered knife includes a casing enclosing an electric motor and a drive assembly for converting rotary motion of the armature shaft into reciprocal motion for a pair of blade holding members, a pair of serated blades adapted to connect with the blade holding members and positioned on both sides of and contiguous with a replaceable thin, flat blade. The serated blades are cooperating first and second support blades defining a channel adapted to receive and provide transverse support for the thin, flat blade.

| 64 | Electric knife blade securing and safety switch device | US3650029D | 1970-05-04 | US3650029A | 1972-03-21 | TRELC WILLIAM F |
| An electric knife having reciprocating carriages supporting adjacent cutting blades, a flexible blade retainer on each carriage cooperating with a blade recess for releasably holding the blade and carriage together, an on-off switch for powering the knife, and a combination blade and safety switch lock device operable in one position to cooperate with the blade retainer only to preclude blade removal while allowing switch operation and operable in a second position to cooperate with the switch only to preclude powering of the knife while allowing removal of the blades.

| A cutting accessory detachably mounted on an oscillating power tool is disclosed. The oscillating power tool includes a head housing and an output shaft extending from the head housing. The output shaft rotates oscillatingly about a longitudinal axis thereof. The cutting accessory includes a housing adapted to the head housing, two movable blades partly received in the housing, and a driving element adapted to the output shaft. The driving element is configured to oscillate by the actuation of the output shaft and simultaneously drives the two movable blades to move in the opposite directions to cut a workpiece. | ||||||

| In an embodiment, a pair of blades, one or both of which is adapted to be reciprocated along a longitudinal axis, comprises a first blade and a second blade, each blade having a cutting edge extending along a portion of the blade length. The cutting edge includes a series of teeth. A width of each blade is stepwise reduced along the cutting edge to the distal end so that one or more teeth from the series of teeth has a cutting surface that is receded relative to a tooth from the series of teeth that is closer to the proximal end. The teeth of the series of teeth are uniformly oriented relative to the longitudinal axis. | ||||||
