Claim 1
Independent Claim
291 words
A hair curling roller apparatus, comprising: a housing having a plurality of concentric annular side walls, including a first side wall, a second side wall, and a third side wall, and arranged in a spaced concentric relationship, with a first top wall mounted to said first side wall, a second side wall mounted to the second side wall, and a third top wall mounted to the third side wall, with the first top wall, the second side wall and the third side wall each including an array of hair curling cylinder container receiving sockets, with each of said sockets having a hair curling cylindrical container therewith, each hair curling cylinder including a central cylinder and a plurality of end flanges, wherein the end flanges are orthogonally oriented relative to and axis of said cylinder, said cylinders having at least one first cylinder cavity containing a silicon gel therewithin, said gel having heat retentive properties, each cylinder including a second cavity spaced from said first cavity, and a central cavity intermediate the first and second cavity, the first cavity and the second cavity each including said silicon gel therewithin, the central cavity having an anchor shaft medially thereof, an elastomeric cord secured to said anchor shaft, with the elastomeric cord having a first end and a second end, the first end including a first anchor lug, the second end having a second anchor, with a first opening directed through said cylinder into said central cavity, and a second opening directed through said cylinder into said central cavity, the first anchor lug being received within the first opening and the second anchor lug being received within the second opening, wherein at least said first anchor lug is pivotally mounted to said elastomeric cord.
