Abstract: 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.

Abstract: 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.

Abstract: An adjustable comb for use on a clipper having one of a first lower blade of first size or a second lower blade of second size. One of these lower blades is an active blade when attached to the clipper. The adjustable comb includes an adjustment mechanism for adjusting the position of a retaining tab that engages a rear edge of the active blade. The adjustment mechanism is shifted in a first direction to position the retaining tab for the first lower blade, and is shifted in a second direction to position the retaining tab for the second lower blade.

Abstract: A blade assembly for a hair cutting apparatus is provided having a first blade having teeth extending along a first blade edge, a second blade positioned proximate the first blade and having teeth extending along a second blade edge parallel to the first blade edge and offset from the first blade edge by a blade gap, a yoke adapted to convert motion of a drive mechanism into reciprocation of the second blade with respect to the first blade, a spring having a spring base and at least one spring arm coupled to one of the yoke and second blade, the spring arm reciprocating with the second blade with respect to the first blade, wherein the spring arm applies a biasing force on the second blade toward the first blade to maintain the first and second blades in an operational condition when separated from the hair cutting apparatus.

Abstract: A hair grooming tool including a housing defining a cavity and including a grooming end, a vibratory motor assembly positioned within the cavity and configured to vibrate the housing, and a pet-engaging member coupled to the housing at the grooming end. Vibration of the housing enables constant motion of the hair tool and movement of the pet-engaging member as the pet-engaging member is pulled through hair to remove loose hair without cutting the hair.

Abstract: A comb attachment for use on a hair clipper includes tines that have rounded free ends positioned rearward of the cutting edge of a lower blade and forward of the cutting edge of the upper blade. Because of a radius of curvature of the rounded free ends, the free ends do not cross the cutting edge of the upper blade during attachment and removal of the comb attachment.
