| 81 | Safety stand and knife and method of use | US11162516 | 2005-09-13 | US07536793B1 | 2009-05-26 | David Joseph Richmond; Juan Fernandez; Paul McGrath |
| The invention provides a safety stand for storing one or more knives or knife blades. The stand may have a lock that automatically retains inserted blades or knives and prevents their inadvertent removal. The invention also provides for methods of using the stand for inserting and removing knife blades without a user having to touch the blade itself, thereby reducing the risk of being cut. | ||||||
| 82 | Hand held knife | US11510904 | 2006-08-28 | US20070270091A1 | 2007-11-22 | Larry Van Vleet |
| 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. | ||||||

| A battery-powered carving knife is shown having a housing and a switch which connects and disconnects a battery to a motor. A drive mechanism including a worm gear together with a cam member causes reciprocation of reciprocating blade mounts to reciprocate back and forth in an out of phase fashion. The motor is positioned forward within the housing in motor receiving section, with the drive shaft of the motor facing rearwardly. The blade mounts are driven by the motor, and reciprocate in a position below the motor. The motor and blade mounts are positioned in front of a handgrip section, thereby improving the ergonomics of the device. Alternatively, the drive shaft can be positioned facing forward. | ||||||
| 84 | Electric knife | US667111 | 1984-10-30 | US4593466A | 1986-06-10 | William J. O'Brien |
| An electric knife of the kind having an elongated handle that serves as a container for a driving electric motor, a pair of blades projecting in an axial direction from the handle, the blades being releasably secured to a drive connected to the motor in such a manner that the blades are reciprocated so as to move in sliding contact with each other the blades having serrated cutting edges, which is characterized by the feature that the line containing the serrated cutting edge of each of the blades is off set from the axis of the handle in such a manner that if the line is extended in the direction of the handle there is a space between the line and any adjacent portion of the handle. | ||||||
| 85 | Electric knife with guide blade | US632717 | 1975-11-17 | US3981078A | 1976-09-21 | Rosette Caroline Alberti |
| An electric knife has two mutually reciprocating cutting blades and an adjustably spaced guide blade. The guide blade is mounted on a cylindrical cap that slidably encloses a cylindrical sleeve fixed to the knife handle, and is rotatable about an axis defined by a threaded rod perpendicular to the planes of the blades and coaxial with the cap and sleeve. A knurled nut on the threaded rod holds the cylindrical cap against a coil compression spring which also acts as a torsion spring urging the guide blade downwardly relative to the cutting blades against an abutment that also serves as a gauge for the thickness of the slices to be cut, manipulation of this knurled nut effecting this adjustment. | ||||||
| 86 | Electric knife | US42109873 | 1973-12-03 | US3861039A | 1975-01-21 | TRUAX EARL S |
| An electric knife having a motorized drive unit contained in a housing and adapted to detachably receive a pair of juxtapositioned cutting blades in a manner disposed horizontally or at a diagonal angle to the housing, the motor including a reciprocating drive unit which is operatively associated with the knife blades for reciprocating such blades relative to each other to accomplish a cutting action.

| 87 | Cutting blades for powered carving knives | US3728792D | 1970-11-25 | US3728792A | 1973-04-24 | GAULT R |
| Each of a pair of blades for use in a powered knife is formed with a bent transverse cross-section whereby the two blades together create a hollow space between the blades, whereby appreciably thinner material may be used as compared with conventional flat blades, thus representing a considerable saving of material and the hollow space acts as a clearance area for any particles or debris created by the cutting action which particles or debris would be liable to create excessive friction between or jamming of conventional flat blades. The blades are preferably made of stainless steel, and the cutting edges are preferably serrated.

| 88 | Motor-driven cutting device | US3646675D | 1970-05-18 | US3646675A | 1972-03-07 | WEZEL HANS GEORG |
| The back of the reciprocating blade of a motor-driven knife is supported for sliding movement near its ends by two wearresistant abutments, and has a central cutout in which a wearresistant guide means is located in sliding engagement with a longitudinal guide edge of the cutout. By transverse adjustment of the guide means, play-free guidance of the blade is obtained.

| A switch controlled electric hand mixer reciprocates releasable dual knives and rotates releasable dual beaters through a short motor shaft worm gear driving three worm wheels having substantially coplanar axes. The switch can be left in ''''ON'''' position when the beaters are present for mixing operations, but it turns ''''OFF'''' automatically if the switch is not manually held ''''ON'''' when the knives are in operative position. The beaters and knives, both are releasable for gravity withdrawal and cleaning by lost motion action of the switch in its ''''OFF'''' position.
