Abstract:
A shaving system utilizing an electric current to heat an electrically conductive razor blade or blades used to cut hair on the skin;the shaving system comprising a cartridge containing at least one of an electrically conductive narrow elongated razor blade of predetermined resistance and a plurality of closely spaced apart parallel electrically conductive narrow elongated razor blades, each of predetermined resistance; a first conductive element connected to one end of the at least one or to one end of each of the plurality of elongated razor blades and a second conductive element connected to the other end of the at least one or to the other end of each of the plurality of the elongated razor blades; a handle adapted to engage the cartridge to provide a means for holding and guiding the at least one razor blade or the plurality of razor blades across the skin to cut hair thereon; a battery having a pair of terminals disposed in one of the cartridge and the handle, an electrical current control system disposed in the handle which is adapted to be electrically connected to the first and second conductive elements of the cartridge when the handle is engaged to the cartridge, the electrical control system having a momentary contact switch with a pair of contacts with one contact being connected to the first conductive element when the handle engages the cartridge, the electrical current control system further having a current control resistor in circuit with the other one of the pair of contacts being connected to the second conductive element of the cartridge, the current control resistor being in series with the one of the terminals of the battery in the cartridge or in the handle; whereby momentary closure of the momentary contact switch enables current to flow from one terminal of the battery through the current control resistor, and through the at least one of an electrically conductive elongated razor blades and the plurality thereof to heat the razor blades for shaving.
