Patent number: 4972584Abstract: A manually portable haircutting and trimming device comprising haircutting blades located in a tubular housing, a motor located at one end of the housing having the dual purpose of driving the haircutting blades and providing a vacuum source for drawing hair from the scalp of a user into the cutting blades and depositing cut hair into a hair storing compartment within the housing, thereby making the haircutting device fully selfcontained. Special air guide means are included to ensure that all hair that enters the hair cutting device, will be cut by the cutting blades. Releasably unidirectional, incrementally adjustable length control means are included to selectively control length of hair remaining on the scalp at various locations as well as means to facilitate crew-cuts, and taper cuts. Special means are included to permit Afro hair cuts without straightening out the curly hair before cutting. Cut-by-numbers means are incorporated permitting the use of hairstyling diagrams with preselected patterns.Type: GrantFiled: March 20, 1990Date of Patent: November 27, 1990Inventor: John H. Baumann

Patent number: 4622745Abstract: The hair trimming apparatus disclosed herein is particularly adapted for trimming beards, mustaches and the like. It includes a hair clipper and a one-piece adjustable comb attachment. The comb attachment is slidably secured to the hair clipper by rails or the like which surround part of the clipper, such as the side edges of a stationary blade. The position of the comb attachment with respect to the blades is determined by placing any one of a plurality of indentations in the attachment over a protruding part of the clipper, such as one or more screw heads which secure one or more of the blades to the clipper. The position may be easily changed by merely moving the attachment to a different indentation. In this manner, the comb attachment may be easily secured to the clipper in any one of a number of positions, without manipulating other parts of the apparatus.Type: GrantFiled: September 28, 1984Date of Patent: November 18, 1986Assignee: Wahl Clipper CorporationInventor: Gregory S.

Patent number: 4520565Abstract: 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.Type: GrantFiled: October 27, 1983Date of Patent: June 4, 1985Inventor: Lynne D. Maggiore

Patent number: 4472878Abstract: 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.Type: GrantFiled: February 1, 1983Date of Patent: September 25, 1984Inventor: Jess Miller

Patent number: 4393585Abstract: 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.Type: GrantFiled: May 11, 1981Date of Patent: July 19, 1983Assignee: U.S. Philips CorporationInventor: Petrus J. J. Nagelkerke

Patent number: 4391040Abstract: A hair cutting unit device for the human head includes a movable open-ended casing in which an electrically operated clipper is mounted on guide means for movement. The blades of the clipper are in the open end of the casing. The position of the clipper with respect to the casing will fluctuate so that the cutting blades are moved away from the open end as the unit is moved upwardly on a head from the lower hairline so as to gradually increase the length of hair being left on the head. Rotary drums and threads in the casing are connected to a fixed member in which the head is positioned to effect translation of the clipper relative to the casing in response to movement of the unit upwardly from the lower hairline.Type: GrantFiled: October 8, 1981Date of Patent: July 5, 1983Inventor: Yukio Kanazawa
