A back massager has folded padding, and upper pillow padding with a frame between the folded padding. The frame has a narrow upper portion and a wide lower portion with two arm portions having an opening between them. A casing comprising two metal pan halves has flat peripheral edges and contains a vibratory means which is attached in the open portion of the frame.

A vibrator motor for electric hair clippers, massagers and the like includes a fixed magnetically permeable piece and a moving magnetically permeable piece. The fixed and moving pieces form a plurality of flux gap zones between selected corresponding surfaces of the fixed and moving pieces. Each of the flux gap zones has an air gap formed between the selected corresponding surfaces of the fixed piece and the moving piece. The air gaps have a total gap surface area, and an apparent gap surface area. The apparent gap surface area can be measured by viewing a selected surface which forms each gap through a plane which is generally perpendicular to the direction of the path of oscillating motion of the moving piece, or through a selected cross-section of the fixed or moving piece which is perpendicular to the path. In this invention, the total gap surface area of the gap in at least one of the flux gap zones is greater than the apparent gap surface area of that gap or gaps.

A blade is provided for use in a hair clipper having a bladeset including a moving blade and a stationary blade, the bladeset being constructed and arranged so that the moving blade is pressed against the stationary blade for allowing the moving blade to reciprocate relative to the stationary blade in a transverse direction to a longitudinal axis of the clipper. The blade includes a base portion having a tooth end, and a mounting end opposite the tooth end, a plurality of teeth arranged in spaced, parallel relationship to each other and projecting from the tooth end, each tooth having a tip and a root opposite the tip and being joined to the tooth end. The roots are joined to the tooth end in spaced relationship to each other to define generally planar-floored channels between the roots for facilitating the evacuation of hair and/or hair clippings from a cutting area of the bladeset. Also, the teeth have a constant rake angle at least from the tip to the root, and the base portion defines a transverse hump area of constant radius designed for further facilitating the evacuation of hair and/or hair clippings from the cutting area.

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. In addition, fins on the comb attachment are recessed behind the clipper blades so that the clipper may more easily reach and trim mustache hair by cutting it in the direction of hair growth.

A vibratory electric motor and appliance embodying same contemplates a pair of shallow pan members which are reversely secured together by means of peripheral portions thereof. The pan members have spaced and aligned generally parallel portions within the peripheral portions which cooperate to mount the vibratory motor. The latter is more or less conventional except that the armature leg which is spaced by a gap from the pole faces of the core-coil assembly has an enlarged width about equal to the spacing between the parallel portions of the pan members. Each side of this widened armature leg has a pair of spaced projections which respectively enter apertures in the parallel portions of the pan members. Thus, when the pan members are secured together at the peripheral portions thereof, the motor is firmly mounted in engagement with both pan members, thereby avoiding auxiliary mounting parts and the assembly time required to install such parts. Also, the appliance is strengthened due to the relationship between the widened armature leg of the motor and the pan members. Also, in some instances the portions of the pan members containing the projection-receiving apertures are inwardly embossed, whereby the strength of the pan members where the motor is mounted is increased further.
