Publication number: 20240066732Abstract: A pad assembly is described that retains a blade assembly or set to the body of a hair cutter. The pad assembly reduces random forces generated by the blade assembly and ensures an accurate and repeatable tension is maintained between the inner and outer blades of the blade assembly. The pad assembly acts as an intermediary between the blade assembly and the body of the hair clippers to reduce challenges associated with fasteners directly attaching the blade assembly to the body of the clipper.Type: ApplicationFiled: October 19, 2023Publication date: February 29, 2024Inventors: Edwin A. Werner, Jassen R. Miller

Publication number: 20230373113Abstract: A blade assembly for a hair cutting apparatus includes a first blade having teeth extending along a first blade edge, and a second blade having teeth extending along a second blade edge. A distance between the first and second blade edges defines a blade gap. A yoke is coupled to the second blade and configured to convert motion of a drive into reciprocation of the second blade relative to the first blade to cut hair. A spring includes a spring base and at least one spring arm configured to reciprocate with the second blade. A guide assembly includes a guide and a spring retainer, the guide being positioned between the first blade and the second blade, and the spring retainer fixing the spring base relative to the first blade, wherein in response to moving the guide relative to the first blade, the blade gap changes.Type: ApplicationFiled: August 1, 2023Publication date: November 23, 2023Inventor: Edwin A.

Publication number: 20230120824Abstract: An adjustable blade attachment is provided that captures an inner blade relative to the outer blade. A mounting bracket captures the inner blade and provides access to attach the blade assembly. A hinge or metallic stamping extends through the mounting bracket and is adjustable to change the force exerted on the mounting bracket. The adjustment to hinge on the mounting bracket changes the tensile force between the inner and outer blade of the blade assembly. In this way, the hinge provides an adjustable component that can increase or decrease the tensile force exerted between the inner and outer blade to adjustably separate the inner and outer blades and reduce friction during operation of the blade assembly.Type: ApplicationFiled: December 22, 2022Publication date: April 20, 2023Inventor: Edwin A. Werner

Publication number: 20220184832Abstract: A haircutter handle is described that has upper and lower housings. The upper housing and lower housing join to form a pliable exterior surface. The handle narrows/tapers as it extends axially from a blade end to a gripping end opposite the blade. The blade has an upper oscillatory blade that oscillates over a stationary lower blade to cut hair. The handle's taper facilitates grasping by locating the motor and battery so that the center of gravity is located within the palm of the user's hand. The width and/or height at the blade end is greater than at the handle or grip end, and the reduction in height and/or width dimensions define the taper to locate the user's hand relative to the center of gravity. In some embodiments, the width tapers more than the height tapers to facilitate gripping handle about the center of gravity.Type: ApplicationFiled: May 12, 2021Publication date: June 16, 2022Inventors: Edwin A. Werner, Jake Schilling, Evan A. Sparks
