CURLING IRON.

Application filed August 14, 1928.

The present invention relates to improvements in curling irons and has for its principal object to provide an appliance for curling hair in an efiicient and reliable manner.

One of the important objects of the present invention is to provide a curling iron particularly adapted to be used in curling the hair while the latter is in a Wet or moistened condition.

A further object is toprovide a curling iron of the above mentioned character which includes a cylinder through which extends a slidable spring pressed plunger, one end of which constitutes a mandrel upon which strands of moistened hair are wound around, additional. means being associated with the opposite end of the plunger and adjacent description.

end of the cylindrical casing for normally maintaining the winding mandrel in an outwardly projected position, said mandrel be ing caused to slide into the casing and be moved out of engagement with the curled hair when the holdingmeans is released, and this without causing any injury to the scalp or disrupting the curl formed.

A further object is to provide a curling iron of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.

Other objects and advantages will become apparent during the course of the following In the accompanying drawings, forming a part of this specification, and in which like numerals indicate like parts through the same: a

Figure 1 is a side elevation of the curling iron embodying our invention showing the normal position of the spring pressed plunger and the retaining means for holding the mandrel in an outwardly projected position,

Figure 3 is a longitudinal sectional View through the device, partly shown in elevation Figure 4 is a view similar to Figure 1 showing the position of the parts when the spring pressed plunger is released or disengaged from the catch,

Figure 5 is a detail perspective view of the plunger per se,

Fi ure 6 is a sectional view taken approxi mate y on the line 66 of Figure 3,

Figure 7 is a rear end elevation showing Serial No. 299,594.

the manner in which the catch engages with the screw threaded cap, and

Figure 8 is a detail perspective view of the spring cap.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of our invention, the numeral 1 designates generally our improved curling iron, the same comprising a cylindrical casing 2, thetorward end thereof being provided with the reduced portion 3 and the outer end of the reduced portion is beveled as shown at 4. j

The opposite end of the cylindrical casing is internally threaded and is slightly onlarged as clearly indicated in Figure 3.

Anelongated plunger rod 5 that is longer than the casing 2 extends longitudinally through the casing and through the reduced portion 3, the forward end portion of said rod constituting the mandrel 6 upon which the strands of wet hair are to be wound in forming the curl and as is clearly illustrated in the drawings, the outer end of the mandrel portion of the rod is slightly tapered and thistaperedportion is denoted by the reference character 7. j

The rod 5 is of a diameter slightly less than the bore of the reduced portion 3 of thecasing 2 and formed on the intermediate portion of this plunger rod 5 is the collar or shoulder 8 the purpose of which will be presently described. The rear end of the slidable plunger rod 5 extends through a threaded bushing 9 that is removably threaded in the rear end of the cylindrical casing 52 and the rear extremity of the plunger rod is threaded as at 10 for receiving the internally threaded cap member 11.

This cap is formed at its outer end with a finger engaging head 12 while at its inner end the same is formed with an annular flange 13.

A normally expanded coil spring 14 is arranged within the cylindrical casing 2, this coil spring encircling the intermediate por tion of the plunger rod 5 and being disposed between the collar 8 and the shoulder 15 formed at the juncture of the casing 2 with the reduced portion 3 as shown in Figure 3.

This coil spring 14 has a tendency to normally urge the plunger rod 5 rearwardly for a purpose also to be presently described.

A laterally projecting lug 16 is formed on the outer face of the cylindrical casing 2 forwardly of the rear end thereof and a similar lug 17 extends from the same side of the casing at the rear end thereof and is disposed in alinement with the forwardmost lug 16. p I p A leaf spring 18 is attached at its forward end on the outer end of the lug 16 and extends rearwardly.

The free end of the leaf spring 18 is attached to a hook shaped catch 19 that projects beyond the rear-end of the casing and this catch has its forward portion normally resting on-thelug 17.

The catch 19 is adapted to engage behind t h'e fiange 18 formed on the forward end of the catc'hineinberll'in the manner as shown in Figures 1,2 and '7 of'the drawings for normally urging th'e plunger rod 5 forwardly against the tensionpf'the coil spring 14 whereby the mandrel portion of the curling iron is projected beyond the forward end of the reduced-portion 3 of the casing 2.

In use, the parts are normally arranged in the manner as shown in Figures 1, 2 and 3 of the drawings; "lhe strands of hair that are moistened are placed around the mandrel portion 6 and by turning the casing 2, the strands of hair will be wound upon the mandrel portion 6. 1

After thisoperation has been completed, the f- 3erson' using the device merely depresses the leaf spring I8 at the point indicated by the arrow in Figure 1 whereupon-the catch 19 is disengaged from'th'e flange 13 and immediately,- the coil spring 14: will exert such pressure-upon the collar 8 as to force the plunger rod 5 rearward-1y through the casing whereby the mandrel 6 is removed from the strands of hair and proj ects into' t-he reduced portion 3 of the casing so as to leave a folrmed curl'.

- T-he curl thus formed may be pinned down' -to allow it to dry and the operation is repeated until the entire head of-hair is curled. 5

will thus be seen from the foregoing description itha't we have provided a curling iron that will save considerable time and labor and furthermore will be efficient and reliablejin its operationand by reason of the' particularshape of the mandrel and the forward end of the reduced portion of the casing, there will be no possibility of the hair being caught or entangled and otherpise causin'g injury -to the scalp orto the ia1r.= 1 7 V The {simplicity of our device enables the same to be readily and easily operated and furthermore "the-parts may be "assembled or disassembled whenever necessary.

' WVhile we h'aves'hown the preferred embodiment-o-fany invention, it is to be understood that 7 various changes in the size, shape and arrailigement of parts may. be resorted to withoutdeparting :lrom the spirit=of the described, a casing, an elongated mandrel of a length greater than said casing adapted for slidable movement through the casing,
