Abstract: An apparatus for cutting hair at a predetermined measured length is provided using a clip device having a first and second jaw member, whereby each jaw member has a clamping portion and a handle member. Pressure applied to the handle members causes the clamping portion to separate, such that a section of hair may be encompassed thereby. Depending from the first jaw member are base spacer attachments arranged to rest on the scalp while grasping the section of hair between the clamping portions. This allows for manual trimming with scissors along the upper edge of the clamping portion. Said section of hair is therefore cut at a predetermined length measured by the combination of the height of the jaw member and the size of the spacer attachments selected.

Abstract: A manually operated hair cutting device having a movable spring wire extending through the device. The wire has a base end for engaging one's head to regulate the length at which the hair is cut. The other end of the wire is connected to an activator which is adapted to be moved to forward and rear positions. As the activator is moved forward, the wire is moved through the device such that its base end is moved away from the cutting teeth. When the base end of the wire engages the head, and the activator is moved forward, the device moves upward along the wire. A movable stop normally prevents the handles from being moved together to prevent hair cutting action. An adjustable engager on the activator engages the stop and moves it out of the way as the activator moved forward to allow the handles to be moved together for hair cutting purposes.

Abstract: A dry-shaving apparatus is provided with hair-trimming means comprising two pairs of cooperating toothed cutters, each pair of cutters consisting of a reciprocatory cutter and a stationary cutter. One pair of cutters is adjustable between different positions and forms a first hair trimmer of relatively short length for trimming hairs which are not easy to get at with a full-length hair trimmer, for example, hairs in the ears. The other pair of cutters either is arranged for operation in line and in juxtaposition with the first pair of cutters in one of the positions thereof so as to form with the first pair of cutters a second hair trimmer of greater length than the first hair trimmer, or has a greater length than the first pair of cutters and forms a full-length second hair trimmer independently of the first hair trimmer.
