US 2002/0053141 A1 · Disposable cutting head for clippers

Abstract

The disposable cutting head is basically a four element clip together assembly with a base, lower and upper cutting blades, and spring. The base serves as the support for the entire assembly and incorporates the attachment elements for retention to a clipper. The spring holds the elements together, forces the cutting blades together and includes the runner under which the upper blade slides. The entire assembly is such that the head assembly with blades is of the disposable type, but uses metal blades. If desired the blades alone may be disposed and the head assembly reused; however, the structure is not intended for long wear and use. The head and blades are constructed such that the common problems encountered with existing removable/disposable heads and blades as for example heat retention in the blades and head and the catching and pulling of hair are minimized. Use with clipper comb elements is also accommodated.
