| 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 proximal end, a distal end, a length extending between the proximal end and the distal end, and a cutting edge extending along a portion of the length to the distal end. A width of each blade is stepwise reduced along the cutting edge to the distal end so that one or more teeth from the a 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. | ||||||

| A battery powered dual blade knife that includes a handle having an interior cavity for containing one or more batteries. The batteries can be removably positioned at the rear portion of the handle. The cavity of the handle includes an electric motor that is generally positioned in the front region of the handle. A pair of blades is connected to the front portion of the handle and is designed to be moved relative to one another by the electric motor. The handle can be designed to waterproof one or more internal components of the knife to protect the one or more internal components from water damage. The knife can include a blade stabilization arrangement for the knife blades and/or mounts for the knife blades to facilitate in the movement of the knife blades and/or mounts for the knife blades when the motor causes the knife blades and/or mounts for the knife blades to move relative to one another. The knife can include an enhanced motor configuration in improve the operation of the knife. | ||||||

| 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. | ||||||

| The present invention 10 is an improved electric knife with several enhancements which make it uniquely suited for use in its intended watery environment. In case it is accidentally dropped in the water, it has several floatation chambers 54 in the handle 24 and the end cap 52 that will keep it afloat and nearly water and damage free for a reasonably long period, certainly time enough for any reasonably serious effort at retrieval to be effective. The end cap 52 is highly buoyant, having a sealed partial vacuum chamber 54. The housing has several sealed buoyant air chambers 54 in the. rearmost area to directly offset the weight of the battery pack 36. The motor housing unit also provides buoyancy and floatation by the presence of the water-resistant seal 63 at the juncture of the knife blades 42 and the handle housing 24. The critical areas around switches 44, 50 and access openings are also watertight for operating in wet or rainy conditions. Additionally, there is a light 48 in the top front area of the handle with its nearby water-sealed 56 switch 50 for illuminating the work area when operating under night or low light conditions. The present invention comes with a carrying case 18 and many additional components: a recharging unit 34 for recharging the power pac 36, a reenergizer 38 for charging the power pac 36 and operating under AC simultaneously, a spare power pac 36, 2 different sized interchangeable blade sets 26, a blade cover 28, DC 12 volt power cord 30, AC power cord 32 and the fillet knife housing unit. | ||||||

| An electrically operated slicing knife includes an axially movable switch guard overlying the switch of the knife. The switch guard is movable to a first position whereat the switch is uncovered and a second position whereat the switch is covered to prevent a user from actuating the switch. A pair of user actuated buttons control ejection of the blade of the knife. When the buttons are in a first position, the blade is locked relative to the knife handle, and the switch guard when positioned to uncover the knife switch maintains the buttons in their locked position. When the switch guard is moved to cover the switch, the buttons can be actuated by a user to unlock the blades from the knife handle. | ||||||

| The electric kitchen knife has blades (2) connected to the front end of a main housing (5), and the blades (2) move in reciprocal motion to cut food. The main housing (5) has a stand leg (6) projecting from the bottom surface positioned away from the center of gravity towards the blade end. The stand leg (6) maintains the main housing (5) in an upright standing position. Held by the stand leg (6) in an upright standing position on a table (7), the front end of the main housing (5) is raised separating the blades (2) from the table (7). | ||||||

| A portable, hand-held electric knife having dual cutting blades is powered by a DC electric motor which draws its operating current from a remote storage battery. The cutting blades are mechanically coupled to the armature shaft of the DC electric motor by a gear assembly in which a pair of bevel gears are mounted for free rotation on a support shaft and are engaged by a beveled pinion gear attached to the rotor armature. Each blade is movably coupled to a selected bevel gear by a pin. In response to rotation of the drive pinion, the beveled gears are driven in counter-rotating motion. As the driven gears rotate, the blades are extended and retracted in side-by-side relation. A fulcrum shaft is received through aligned slots formed in the blades. Linear reciprocating movement of the blades relative to each other is stabilized and arcuate reciprocating movement of the coupled blades is effected as the blades pivot about the fulcrum shaft. According to this arrangement, the coupled blades undergo simultaneous linear reciprocal movement along parallel paths of extension and retraction, and arcuate reciprocal movement about a path transverse thereto. | ||||||
| 60 | Blade set for an electrical knife | US814737 | 1985-12-30 | US4677749A | 1987-07-07 | Marc P. Brison |
| A blade set for an electrical knife comprises two parallel extending blades arranged adjacent with their inner faces facing and joined to one another. In use, for example, for slicing bread, the two blades are alternately reciprocated by the drive motor of the knife. Each blade has a series of indentations in its lower edge between which projecting teeth are defined. The tip of each tooth has a small concave notch, in the form of a circular arc, which extends between the edges of the tooth and which has a chamfer. The ends of this notch form two spaced points. | ||||||
