With Heated Clamp Means (e.g., Hand-held) Patents (Class 219/225)
  • Patent number: 4210797
    Abstract: A curling iron includes a tubular barrel extending forwardly from a hollow handle. The barrel contains an electric heating element and is provided with a spring-biased pivotable hair holding clamp conforming to the surface of the barrel. The barrel and clamp are pivotal as a unit about 180 degrees from the extended operative position into a folded storage position within the handle through a side opening in the handle. The opening is closed by a pair of inwardly pivotable doors which are spring-biased to an outward closed position conforming to the outer surface of the handle. Pivotal movement of the barrel from its extended position causes contacts on the barrel to separate from spring contact elements fixed in the handle to disconnect the heating element from its electric power source. As the barrel and clamp are folded into the handle through the opening, the doors are pushed inwardly out of the way so that the handle may receive the barrel and clamp for storage.

  • Patent number: 4209685
    Abstract: An appliance or device for treating hair includes a tubular barrel containing a generator for heat and vapor and a plurality of hair winding mandrels which are slidably mounted over the tubular barrel. The mandrels have different external sizes and configurations, but have interior structures which, though they may differ, allow each mandrel to be used with the same tubular barrel. A mandrel for straightening strands of hair when moved relative to the strands and for waving strands of hair when held stationary relative to the strands is provided. The mandrel is adapted to be removably associated with the tubular barrel. In the preferred embodiment, the mandrel is comprised of a heat-treating surface having a sinusoidal configuration. Apertures through the surface convey vapor from the vapor generator in the tubular barrel to the strands of hair engaged therewith.

  • Patent number: 4163143
    Abstract: An improved hair dressing device of the curling iron type having a heatable barrel is provided, along a longitudinal segment thereof, with a plurality of radially projecting hair combing teeth having substantially pointed ends. A hair-confining member, generally coextensive with and overlying the barrel segment in operative position, is pivotally mounted to the barrel, adjacent its rearward end for movement between the operative position and a non-operative position away from the barrel. Stop means are associated with the member for maintaining the same in spaced relation to the barrel and to the ends of the teeth in the operative position so as to essentially limit and minimize clamping pressure on hair confined between the member and the barrel to allow the hair to slide therebetween as the barrel is rotated during use, with a minimum possibility of hair being caught between the member and the ends of the teeth.

  • Patent number: 4101756
    Abstract: A stand for holding one or more heatable hair curlers or curling irons has a well or receptacle for each curling iron, each well having two contact poles connecting through normally open switches to a source of power to the stand. Each curling iron has a heating element thermally connected to a hair mandrel and electrically connected to separated electrical contact zones on the iron beyond a thermal insulating handle. The handle terminates remote from the mandrel in a reduced actuating tip that passes a restriction in a receptacle and moves a switch actuator to close the switches and supply current to the curling iron heating element, through the contact poles and contact zones. Removal of the iron from the stand closes the switches and no current flows.

  • Patent number: 4100397
    Abstract: An electrical heater assembly comprising a heat generating element and a temperature regulating device supported by a heat conducting core of electrically insulating material is constructed to provide a thermal path for conducting heat from the heat generating means to the temperature regulating device with minimum thermal resistance, whereby temperature fluctuation is minimized. The temperature regulating device is substantially encircled by terminal means electrically coupling the temperature regulating device in circuit with the heat generating element. The temperature regulating means is disposed substantially entirely within a cavity in the core so that substantially all of the outer peripheral surface of the terminal means is in friction contact with the surface of the cavity.

  • Patent number: 4097718
    Abstract: A hair curler includes an apertured cylindrical shell about which hair to be curled is wound. Mounted within the shell are two semicylindrical mounting components which donfine between themselves a plurality of spaced apart pill-shaped PTC resistor bodies. The engaging surfaces of the pill-shaped resistor bodies and of the semicylindrical mounting components are complementary and cylindrical, to establish good electrical and thermal contact between the engaging surface portions. Voltage is applied across the two semicylindrical mounting components, causing the generation of heat within the PTC resistor bodies. The PTC action of the latter causes an automatic limiting of temperature, preventing damage to hair. The generated heat is transmitted to a heating plate in contact with a wick extending into a water container. Water evaporates from the wick and steam passes into the interior of the apertured cylindrical shell, out through the apertures thereof, and into contact with the hair wound around the curler.

  • Patent number: 4065657
    Abstract: A curling iron, having a single stepped barrel having a different diameter at each step, to enable a hairdresser to perform lift operations for providing body and gentle curvature to the hair, and curl operations for curling the ends of the hair, without changing curling irons. The iron can also be effectively used to make a number of different size curls in the same strand of hair. The barrel sections of different diameter sizes are arranged substantially tangent to one another, instead of being concentric, so that the clamp which clamps hair against the barrel section can function without large steps therein which might snag on hair and also permits hair to be smoothly slid from one barrel section to the next.

  • Patent number: 4034201
    Abstract: An appliance or device for treating hair includes a tubular barrel containing a generator for heat and vapor and a plurality of hair winding mandrels which are selectively slidably mounted over the tubular barrel. The mandrels have different external sizes and configurations, but have interior structures which, though they may differ, allow each mandrel to be used with the same tubular barrel. In one embodiment, the vapor and heat are conveyed from the tubular barrel to the exterior surfaces of the mandrels to treat hair by fins which form ducts within the mandrels that extend radially inwardly toward the tubular barrel. There are apertures both in the mandrels and the tubular barrel with which the ducts register to convey the vapor. Pivoted to each mandrel by means of a sliding pivot is a clip having a clamping portion for initially engaging hair before the hair is wound around the mandrel.
