Abstract
Abstract A new and improved preheated having a unique heating means incorporated therein. The curler includes an insulating jacket having an internal insulating sleeve extending axially therealong with the heating means encapsulated therebetween, wherein the heating means comprises the greatest mass of the curler. The curler is inserted into an energizing unit having thermostatic control means which engages the sleeve and limits the curler temperature to a predetermined value. The curler is rapidly heated to the predetermined temperature which can be a relatively high temperature and, since the heating means is contained within an insulating jacket, it may be applied to the hair before becoming warm to the touch. The curler also retains and provides heat for a relatively long period of time.

Claim 5
Dependent Claim
58 words
An apparatus in accordance with claim 1 wherein: The energizing unit includes an aperture, the second contactor being mounted therewithin, and said second contactor includes a socket portion, contact means extending outwardly therefrom to engage the first contactor, and wherein said temperature control means extends upwardly from said contact means to engage the insulating sleeve of the curler.
Claim 6
Dependent Claim
76 words
An apparatus for curling hair in accordance with claim 4 wherein the first contactor includes a pair of spaced contact elements connected to the heating element, and the contact means of the second contactor mounted within the energizing unit includes a pair of formed metal contact elements each designed to engage a respective one of the contact elements in the first contactor and the temperature control means includes a thermostat having a perforated cover mounted thereover.
Claim 7
Dependent Claim
62 words
An apparatus for curling hair in accordance with claim 1 wherein: the energizing unit includes switch means for actuating said unit, relay means activated by the switch means to remain operative during a heating interval and said temperature control means includes a thermostat mounted to the second contactor and having means for deenergizing the relay when a predetermined curler temperature is reached.
Claim 8
Independent Claim
183 words
An apparatus for curling hair comprising: a curler having an insulating outer jacket, an insulating sleeve extending axially within the jacket, a heating element mounted between the jacket and the sleeve, means for sealing the heating element at the ends of the jacket to contain said element between the jacket and sleeve and thereby minimize heat transfer, a winding knob having a projecting portion which extends into one end of the sleeve to retain the knob in position and a contactor secured to the curler at the other end of the sleeve and having first contact means connected to the heating elemeNt, and an energizing unit having an aperture therein and a contacting unit mounted within the aperture, said contacting unit comprising second contact means for engaging the first contact means on the curler contactor, temperature control means extending outwardly form the aperture on the energizing unit insertable in and engaging the sleeve to control the temperature to which the curler is heated, and means for supplying power to the heating element from the energizing unit through the second and first contact means.
