1 Claim. (Cl. 132-41)
This invention relates to a tensioned spring steel clip
?at face 15 positioned to engage a coil of hair on the
cylindrical member B.
The ?at bar .14 is provided with a right angle twist, as
indicated at 16, so that beyond the right angle twist #1-6
the bar may be bent to provide the angular extension i7,
having a toothed edge 18 provided with spaced teeth 19

tensioned spring steel clip terminates in a projection 21
Many forms of so-called hair curlers have been pro
posed in the prior art, most of which are overly complex
and impractical.
‘It is the primary object of the present invention to
provide a tensioned spring steel clip universally ap
plicable to the conventional form of hollow cylindrical
member on which strands of hum-an hair are coiled.
‘It is a more detailed object of the invention to provide
a tensioned steel spring clip formed in a unitary struc
ture and which requires the application of manual force

hollow cylindrical member on which a strand of hair has
been coiled.
Still more speci?cally it is a more detailed object of the
extending in the direction away from the end 2%} of the
hollow cylindrical member vB, to which the spring steel
clip -A is adapted to be applied.
The spring steel clip A is adapted to be heat treated,
tempered and tensioned so that the inner edge 18 of the
angular extension 17 carrying the teeth 19 is at all times
biased toward the hook 11. Conventional hollow cylin
drical rollers, such as illustrated at B in the ‘drawings, are
usually about 2 inches long and about 5/8 of an inch in
diameter. These dimensions may vary and likewise spring
slips embodying the present invention may be supplied in
varying lengths, each length being applied to hollow
cylindrical members of corresponding dimension. The
