HAIR CURLING DEVICE Filed Oct. 29, 1954 Patented July 20, 1937 UNITED STATES PATENT OFFICE 5 Claims.

This invention relates to new and useful improvements in hair curling devices.

One object of the invention is to provide a hair curling device having improved means for substantially eliminating back lash or backward. rotation of the hair-winding roller.

A particular object of the invention is to provide improved means for frictionally holding a hair-winding roller against reverse rotation, whereby the roller may be freely rotated in one direction to wind the hair thereon, but is positively held against unwinding, so that there will be no slippage or loosening of the wound hair.

Another object of the invention is to provide a holding device for the hair-winding roller of a hair curling device, including resilient means arranged to co-act with a stationary member, so that upon imparting a winding movement to the roller and utilizing the torsional movement of said means, the roller may be freely wound, but will be positively held against unwinding, so that when the winding operation is stopped there will be no loss by slippage due to unwinding.

Still another object of the invention is to provide a latch serving to hold its hair-winding roller in its frame and also co-acting with the retaining means to fasten said roller against unwinding.

A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing, in which an example of the invention is shown, and wherein:

Figure 1 is a perspective view of a hair curling clamp constructed in accordance with the invention, the roller being omitted,

Figure 2 is a perspective view of the hair-winding roller for the clamp shown in Figure 1,

Figure 3 is a side elevation of the complete clamp,

Figure 4 is an enlarged transverse vertical sectional view taken on the line 4-4 of Figure 3 showing the latch open,

Figure 5 is a similar view taken on the line 5-5 of Figure 3,

Figure 6 is an enlarged detailed vertical sectional view of the retaining means, and

Figure 7 is a vertical sectional view taken on the line 'I-- of Figure 3. v

In the drawing the numeral I designates the frame of a hair curling clamp, such as isV commonly used in hair waving devices to produce what is known as a Croquignole wave or the like. The frame includes a pair of parallel clamping bars II and I2 which are encased in exible sleeves or jackets I3. The bar II has a cross head I I at one end directed at substantially right angles thereto.

A bracket lll is bent upwardly from the outer transverse edge of the head. The other bar I2 has one end pivoted to the head and it is obvious that said bar I2 may be swung away from and toward the bar II to open and close the clamp. When the clamp is closed, the sleeves intimately engage each other along their entire lengths, whereby strands of hair may be clamped therebetween.

A bracket I is bent upwardly from the outer end of the bar I2 and at the opposite end of the clamp to the bracket I4. This bracket I5 is offset, whereby a notch I6 in its upper end is disposed relatively between the sleeves. The bracket I5 is provided with a swinging hook Il having a downwardly extending bill I'I for engaging a stud or keeper I8 on the adjacent end of the bar I I, whereby the ends of the bars may be hooked together.

The upright bracket I 4 is provided with an outwardly directed ear I9 at one side of its upper end. A latch 26 is pivoted on the ear and is formed with a thumb piece 2l and a downwardly extending bill 22. 'I'he upper portion of the bracket I4 is provided with a transverse slot 23 which extends inwardly from the side opposite to that on which the ear is located. (Figures 1, 4, and 5).

As is shown in Figures 2 and 3, a hair-winding roller 24 is provided for rotatable mounting in the brackets III and I5. This roller has the usual hair keeper 25 hinged thereon for confining the ends of the hairs, previously to winding the hairs on said roller. At one end, the roller has a trunnion 26 for engaging rotatably in the notch I6 of the bracket I5; while on the opposite end of said roller, a sleeve 2l, polygonal in cross-section, is rotatably mounted with relation to said roller 24, but with non-rotatable engagement in the slot 23 of the bracket I4, the preferred cross section of said sleeve 2'I being hexagonal, as shownv more clearly in Figure 7 of the drawing.

The end of the ro-ller 24 on which the sleeve 21 is mounted is provided with a cylindrical central recess or Vsump`28. An axial stub shaft 29 extends through the recess and is securely fastened in the roller, while the other end eX- tends longitudinally from the roller. A knurled knob 30 is mounted on the outer end of the shaft it is held against rotation.

29 for rotating the roller. A coiled spring 3l surrounds the shaft intermediate its ends. One end of the spring 3l engages in the recess 28 and the other end bears against the inner face of the knob Sil (Figure 6). Said spring 3| also normally bears circumferentially upon the inner wall faces of said sleeve 21. The latch 20 is shaped to engage the angular outer faces'` of the sleeve 2l and being pivoted on the outer side of the bracket It swings down between the knob 30 and said bracket.

When the parts are assembled the spring 3I is partially wound, so that when placed in the sleeve 2 and recess 28, it will slightly unwind,A

inner VwallY wise against the bottom of the recess andthe inner face of the knob 30. rIhe frictional fastening between the spring and the roller anda like engagement between the spring and the sleeve, causes said spring to be twisted when the knob 3@ is rotated in the direction to Wind the strands of hair on the roller. This is due to the fact that one portion of the expanded spring is in irictional engagement with the stationary sleeve, while the other portion is frictionally held in the rotating roller. y

When the spring is` twisted by turning the knob, it is wound and thereby retracted slightly in diameter, which breaks its frictional engagement with the sleeve, thus releasing the roller 24 and permitting it to be freely rotated to wind the strands of hair thereon. However, when the winding is stopped or an attempt is' rnade to reve-rse the rotation of the roller, the clearances are such that the slight expansion of the coiled spring, due to its torsional movement, will quickly set up the frictional engagement between the spring and the sleeve, thus holding said roller against unwinding or back lash.

In using the hair clamp, the roller 24 isirst removed from the frame as is shown in Figure 2. The keeper 25 is swung open and the ends of the strands of hair which are to be curled are placed under said kkeeper and partially wound around the roller, whereby the keeper is clamped in position. rlloe hair is wound on the roller up to a short distance from the head of the person. The clamping bars Il and I2 having been spread apart, the clamp may be inserted between the roller and the head of the person. By swinging the bars together the hair will be gripped between the sleeves I3, when the hook Il is engaged over the stud I8.

rllhe clamp being fastened in position, the roller with the hair wound thereon may then be placed in the frame IB, the trunnion 26 being inserted in the notch I6. When the trunnion is inserted in the notch, the sleeve 2l is swung into the slot V23 and the latch 20 is then swung down to fasten said sleeve in` the slot, whereby rThe operator now grasps the knob 30 and rotates the same so as to continue winding the hair on said roller, until all of the slack is taken up. It is obvious that, when the knob is turned to wind the hair on the roller, the coiled spring 3| will be slightly wound, thereby releasing its friction grip within the sleeve. When the knob is released, the torsion of the spring will tend to unwind the same and this will reestablish the friction grip with the sleeve, whereby the roller will be held against unwinding, and consequently there will be no back lash or slippage and the hair will be tightly held.

It is obviousl that this holding device is positive in its operation and is not dependent upon teeth or pawls. The spring being entirely enclosed there are no points exposed which might catch or break the hair and the operation of the device will not be affected by the usual Wear and tear.
