A low wattage device for heat-liquefying material is described which employs a low volume mass electrical heat exchanger structure to generate a high power density within a dispensing tip; and simultaneously by actuation of an operator controlled momentary on/off switch for energizing the heat exchanger structure heater, the heat-liquefiable material is pressed into effective contact with the heat exchanger structure. The heat exchanger structure is formed by positioning a resistive heating element in contiguous relation to the outer wall of a low volume thermal conducting mass formed into a heat-liquefying material conductor and generates sufficiently high heat at a relatively low wattage to effectively achieve the desired melting within a few seconds. In a further feature, an insulating shield partially envelopes the heat exchanger structure to prevent contact with the resistive heating element and to minimize heat loss.

A tool for cleaning between hair clipper blades includes an elongated handle with a comb at one end of the handle. The comb has a plurality of spaced teeth separated by openings, and a finger at one end of the comb. In use, the finger is inserted between the clipper blades, separating them so that the comb can be passed through the space between the blades, removing unwanted matter such as uncut hair strands.

Method and appartus for cleaning hair clipper blades

A blade assembly for electric hair clippers includes a stationary blade having a plurality of teeth arranged in a row, and a reciprocating blade having a plurality of teeth which complement the stationary blade teeth. A cam eccentric which is turned by a shaft attached to a motor moves the reciprocating blade in a back-and-forth motion through a set operating stroke, determined by the lateral distance the cam moves during its rotation. A guide bar maintains the reciprocating blade in a blade guide parallel to the stationary blade throughout the operating stroke, but not through the maximum stroke the blade can travel when the head assembly is removed from the handle for cleaning or other servicing. Anti-lock ribs or an anti-lock bar are provided on the blade guides to engage the guide bar throughout the maximum stroke distance, thereby maintaining the reciprocating blade parallel to the stationary blade throughout the maximum stroke. The blade assembly is removably secured to the handle of the clipper by snaps or the like without the use of screws.
