Patent number: 11919182Abstract: A blade cap is provided to shield a user from heat generated by operation of a blade assembly. The blade cap provides an insulative barrier between the blade assembly and the skin of the user. The blade cap may prevent discomfort or burns from the heat generated by the blade assembly. The blade cap includes openings, channels, projections, tabs, and other formations to allow the flow of air through the passageways between the blade cap and the blade.Type: GrantFiled: November 30, 2021Date of Patent: March 5, 2024Assignee: Andis CompanyInventors: Richard J. Tringali, Jeffrey D. Gross, Joseph Novak

Publication number: 20230107628Abstract: A linear actuator or motor for oscillating a blade is provided. The linear actuator replaces an eccentric drive and yoke, resulting in a linear powered drive to oscillate the blade linearly. This operation facilitates the formation of a smaller and/or lighter hair clipper. The linear actuator uses alternating current to oscillate a permanent against a biasing force produced by a set of springs. The permanent magnet is located opposite a stator with an electromagnetic coil that generates an electromagnetic force to oscillate the permanent magnet.Type: ApplicationFiled: December 8, 2022Publication date: April 6, 2023Inventors: Richard J. Tringali, Jeffrey D. Gross

Publication number: 20230023892Abstract: A hair clipper or cutter is provided with an adjustment slider that adjusts the gap between an inner and outer blade. A yoke is attached to the inner blade. The adjustment slider may be configured with preset gap lengths and may be adjustable before, after, or during a hair cutting operation. A T-guide couples the adjustment slider to the inner blade to slidably move the inner blade relative to the outer blade. The yoke, inner blade, outer blade and/or T-guide may be magnetized to create an attractive or repulsive force between the inner blade and the outer blade. In some embodiments, the yoke is not metallic. The magnetized yoke may be a non-conductive magnet carrier (e.g., plastic) or conductive material (e.g., ferromagnetic).Type: ApplicationFiled: September 22, 2022Publication date: January 26, 2023Inventors: Edwin Alen Werner, Richard J. Tringali, Ervin Titzkowski, Joseph Novak, Jeffrey D. Gross

Publication number: 20200384661Abstract: A hair cutter with an energy storage device is provided. The energy storage device is connected to the motor through a circuit that powers the motor to oscillate a translating blade over a stationary blade. When the hair cutter is operating the energy storage device is discharged. When the energy storage device is completely discharged, the hair cutter is recharged, for example, by connecting the hair cutter to a power outlet. The electrical circuit connects the energy storage device to a voltage and/or current input to charge the energy storage device. The electrical circuit may also transform the input. For example, the circuit may transform an AC input (e.g., 120V, 12 A) to a DC input (e.g., 4.7V-5.5V, 2.5 A) when the energy storage device is a supercapacitor.Type: ApplicationFiled: June 8, 2020Publication date: December 10, 2020Inventors: Richard J. Tringali, Robert E. Derby

Patent number: 8051571Abstract: A hair clipper includes a housing and a blade assembly coupled to the housing. The blade assembly is coupled to the housing at a cutting end and is movable between an operating position and an open position. The clipper also includes a release assembly including a release mechanism. The release assembly is switchable between a hold state and a release state. In the hold state, the release assembly holds the blade assembly in the operating position. In the release state, upon application of a force on the release mechanism, the release assembly releases the blade assembly to permit the blade assembly to move to the open position in the absence of an additional force.Type: GrantFiled: August 30, 2005Date of Patent: November 8, 2011Assignee: Andis CompanyInventors: Matthew L. Andis, Richard J. Tringali, Andrew A. Skuhra
