HAIR CURLER Filed Augfl'r, i955 United States Patent HAIR CURLER yRobert Trahish, Chicago, Ill. Application August 11', 195s, serial No. 529,010

s claims. (ci. 132-34) structed that the entire device is easily disengaged from a curl immediately after the forming thereof in preparation for use to form other curls. Moreover, since it accomplishes the desired results equally as well when individually used as when it is manipulated by another person, such as a beautician or hair stylist, the invention is adapted for both professional beauty parlor use or use by an individual in the home. Actually, when using the invention, the hair curling operation is so simple that it can be done entirely by feel rather than requiring the use of a mirror as a visual aid.

The hair winding portion comprises means preferably consisting of a cylindrical comb structure adapted to engage and grip a lock of hair, and an idler on which the entire'device may be supported as the grip and lock of hair held thereby are spun to form a curl. To turn the grip, an actuating mechanism is provided in the body and handle of the device and attached thereto. Specifically, grip rotation is accomplishedV by Va, steep pitchedscrew and ratchet and pawl arrangement cooperable therewith as the handle isrmoved inwardly axially into the body; while withdrawal of the handle outwardly from the body disengages the actuating mechanism, leaving the grip free to remain stationary.

Curls and ringlets generally are tediouslyformed by hand with the aid of combs, pins, and other devices slow to manipulate to achieve the desired effect. Many forms of hairdressing appliances are known to women. Some require the user to wear them for hours before they are etective. Other appliances require the use of heat or chemical solutions for effective results. Repeated usage of them may permanently injure the scalp or hair.

Still other hair curling devices have sharp edges and projections likely to cut the scalp of the user as the hair is being set. Many other curling devices are expensive and complicated, requiring that they be used only by specialists; while others, because of their many working parts, easily are subject to misalignment and breakage;

And, those devices which are presently known to form curls and ringlets are time consuming to use, and more often than not produce inferior results.

Accordingly, it is an object of this invention to overcome these and other failings of prior known hair curling devices.

It is a principal object of the invention to provide a simple to use and highly eiiicient hair curling device which produces curls and ringlets with a minimum of eiort and .in a minimum of time. Y

Another object of this invention isito provide a rotatable hair grip -and hair curling head, and further to pro.-

ifice a device for professional use and for individual use, and

. which readily engages and grips the hair to thereafter almost automatically produce curls or ringlets as desired. And still. another object of this inventon is to produce a hair curling device which is inexpensive to manufacture, strong and durable in use, and easy to manipulate; and to this end it consists of the n ovel elements and combination of elements hereinafter described and defined in the claims.

The foregoing and other objects, advantages and features of construction will become apparent from a consideration of the following description and the appended drawings.

vide actuating mechanism therefor effective to turnithe In the drawings:

Figure 1 is a perspective view of the invention in operative position;

Figure 2 is a cross-sectional view taken on lines 2--2 in Figure l, showing the operating mechanism in extended position;

Figure 3 is a view similar to that shown in Figure 2, but showing the operating mechanism after the curling head has been spun;

Figure 4 is a view similar to those shown in Figures 2 and 3, showing the operating mechanism after the release thereof for return to extended position;

Figure 5 is a view taken on lines 5-5 in Figure 3; and

Figure 6 is a view showing the cooperating ratchet and pawl mechanism for controlling the curling head.

The herein disclosed device comprises three principal portions; namely, the curling head, a cylindrical body wherein the head is held for rotation relative thereto, and a handle and actuating mechanism for rotating the curling head.

Referring to the drawings, the curling head 10 includes a hollow cylindrical body 11, one end 12 of which has teeth 13 and cutout portions 14 alternatively provided about its cylindrical circumference, and forming an annular comb for engaging and holding the hair during the curling operation. Adjacent its other end of the cylindrical body 11 is formed into a chamber 15 having an enclosure member 16 and a capping member 17. The enclosure member is provided with a central aperture 18 through which an idler stem 19 slidably passes into chamber 15. Within the chamber the idler stem 19 is provided with a gear 26 having teeth 21 adapted to engage teeth 22 provided on enclosure member 16 when the idler 19 is moved outwardly with respect to cylindrical body 11.r Capping member 17 and a collar 23 limit the v relative movement between the idler stem 19 and cylin- A helical spring 31, mounted concentrically within housing 25 and against capping member 17, urges the handle and curler actuating mechanism 30 outwardly to the extended position shown in Figure 2.

The handle and actuating mechanism comprises a cylindrical piston 32, preferably enlarged at the outer end to provide a convenient handle portion 33, and having anaxial bore 34 extending therethrough. An annular retaining shoulder 35, engageable with the end 36 of housing 25, limits the axial movement of piston 32 to within tin-(housing. :j l
