C. A. YOUNG SACHET COMPRESSOR Filed Aug. 23, I958 Patented Dec. 20, 1938 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to hair waving implements and consists in a sachet compressor for clamping sachets tightly around the rollers upon which the hair is wound before being treated 5 with heat.

It is the general practice in permanent waving processes to draw a hank of hair through a clamp faced with rubber and wind the hank on a roller which fits on the clamp. A sachet consisting of a paper-backed cloth leaf is dipped into a specified solution and then wrapped around the roller carrying the hair. Subsequently electric heating elements are disposed around the sachet for steaming the roll of hair. It often happens 15 that sachets fall off prior to the application of the heating elements and the'work is thus annoyingly delayed. Furthermore when the clamps have been used for a substantial length of time, they become worn so that steam sometimes es- 20 capes around the hair and burns the scalp of the customer. These disadvantages result from the fact that it is impossible to pack the sachet tightly around the roller with the fingers because the clamp blocks off the bottom of the roller.

25 The chief object of my invention is to provide a tool by the use of which sachets can be tightly wrapped around the roller and compressed thereon to prevent them from falling off and also to prevent escape of steam through the clamp.

3 Another object of the invention is to shorten the time necessary in waving hair by providing a simple tool which will wrap a sachet securely around a roller in one easy operation.

One feature of the invention resides in a novel 35 pair of wrapping jaws so shaped and arranged as to press the sachet completely around the roller regardless of the thickness of the hank of hair thereon.

These and other objects and features of my in- 4 vention will be more readily understood and appreciated from the following detailed description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawing, in which:

45 Fig. 1 is a view in perspective of a sachet compressor.

Fig. 2 is a fragmentary view in end elevation.

Fig. 3 is a view partly in cross section and partly in perspective showing the operation of the compressor.

Fig. 4 is a view in perspective of a sachet.

As shown in Fig. 1 the sachet compressor includes a straight handle member ID having an opening at its lower end for the operators fingers 55 and being formed of steel or other suitable metal.

Pivotally connected to the handle member I0 at I2 is a second handle member II provided with an opening for the thumb of the operator and bent sharply adjacent the opening for the thumb. The opposite ends of the handles I0 and II are 5 provided with integral complementary jaws I3 and I4. The jaws I3 and I4 are considerably elongated and are arcuate in cross section. They extend symmetrically and transversely with respect to the handle members. As will be seen in Fig. 2'the jaws I3 and I4 are arranged so that when-the instrument is closed the outer longitudinal edges of the jaws are in contact and the inner edges of the jaws are spaced apart.

The operation of the compressing implement will be apparent from an inspection of Figs. 3 and 4. A hank of hair I5 is drawn between two flat clamping members It and I! which are faced with rubber or felt I8. After the hank I5 is drawn between clamping members I6 and I1, it is wound upon a roller I9 which is rotatably journaled in brackets extending upwardly from the clamping members I6 and I1. Apawl, not shown, prevents unwinding of the roller I9. After the hank I5 has been wound upon the roller I9, a sachet 2i which comprises a cloth leaf 22 and a paper backing 23, is separated and the cloth leaf 22 dipped into a solution, which may be any one of the solutions commonly used in waving hair. The wet sachet 2I is then loosely wrapped about the roller I9 and the sachet compressor is applied over the roller and the sachet and then squeezed so that the edges of the jaws I3 and I4 press the sachet 2I tightly around the roller I9. In this connection, it is necessary that the inner 5 edges of the jaws I3 and I4 be spaced apart. If the jaws I3 and I4 fitted tightly around the periphery of the sachet on the roller, compression of the instrument would squeeze out the greater part of the solution with which the cloth leaf 22 is impregnated. Further than that the size of the hanks of hair being treated may vary and if a large hank is being treated, the sachet will bulk beyond the inner edges of the jaws I3 and I4. The steps in the process after the application of the sachet do not form any part of my invention, but for a more complete understanding of the factors involved it may be stated that electric heating elements are subsequently applied and steam is generated from the solution contained in the sachet. If the sachet is not tightly wrapped under the roller, it is possible that steam may escape between the members I6 and I1 and burn the scalp of the customer. Furthermore, after the sachet has been tightly wrapped by the com- 5 pressed with a compressor constructed according to my invention.

In the so called machineless processes of hair waving the sachets are previously impregnated with unslaked lime and dipped into water so that 10 intense heat is generated. With this process no external heating appliances are used and the sachets would be free to fall ofi unless special clips were used. However, by using the compressor of my invention it is possible to practice 5 machineless waving processes without using special clips to hold the sachets around the rollers.

It will now be evident that I have disclosed a novel sachet compressor which can be easily and inexpensively manufactured and which, in addi- 20 tion to saving time, obviates the danger of burning customers and makes the use of special clips unnecessary.

Having thus described and illustrated my invention what I claim as new and desire to secure 25; by Letters Patent of the United States is:

1. A sachet compressor which comprises, a pair of pivotally connected members, an elongated arcuate jaw on each member so arranged that the outer edges of the jaws come together when the members are squeezed together and the inner jaws are spaced apart, the inner surfaces of said jaws forming a continuous are.

2. A sachet compressor which comprises a pair of pivotally connected pliers, arcuate jaws disposed on adjacent ends of said pliers approximately equal to the length of a sachet, said jaws being constructed and arranged to meet at one edge only when said pliers are squeezed, the other edges of said jaws being spaced apart.

3. A sachet compressor which comprises a pair of V pliers, transversely elongated jaws on said pliers, the jaws being so shaped that compression of the pliers serves to bring the outer edges of said jaws in contact while the inner edges are spaced apart.

4. A sachet compressor which comprises, a first member having a straight handle portion and a curved portion, a second member having a bent handleportion and a curved portion, a pivot connecting said-members between the handles and the curved portions, a pair of elongated arcuate jaws symmetrically disposed on the curved portions of said members, only the outer edges of said jaws being in contact when the compressor is closed.
