Patented Apr. 20, 1937 UNITED STATES PATENT OFFICE Y 19 Claims.

The present invention relates to mandrels on which locks of hair are wrapped to be treated and curled.

One of the primary objects of the invention is to provide means where the coiled hair after it has been wrapped on the mandrel, can be placed under additional tension so as to insure that the coil is very tightly wrapped-a condition that is essential to the best results, and one that so far as I know has heretofore been accomplished only by putting tension on the hair as the lock.l is wrapped.

A further and important object is to provide effective means for clamping the base portion of the lock so that the danger of pulling the hair and causing inconvenience to the person whose hair is being treated, is eliminated and at the same time the mandrel is effectively secured in place.

20 A still further object is to provide novel and elective means for securing the free end portion of the lock of hair after it has been wrapped on the mandrel.

In the embodiment disclosed the mandrel is composed of two sections, which for the purposes 55 of distinction are designated as the body section and the stretcher section. The body section is designated I3 and is in the form of a rod having a head I4 at one end and a longitudinal cutawaiT portion I5 at its other end. The head is connected to the main portion of the section by a 5 recessed part I6, providing a chamber or space I1 with an entrance mouth I8. This head portion has an extension I9 partly extending across the chamber and creating a hooked formation.

The head I4 has an annular channel 2l) cut l0 across on one side by a recessed hair-receiving seat 2| that opens into one side of the chamber I1 (see Figure 7). The inner end of the head is beveled, as illustrated at 22, and said end has an annular groove 23 on the outer side of 15 the portions I6 and I 9. A sleeve 24, slidable longitudinally upon the body section I3, is movable across the entrance mouth I8. and the adjacent end will enter the groove 23. This sleeve carries a crescent-shaped hair-clamping jaw 25 20 operating in the chamber I1, and cooperating with the adjacent end wall of the head I4 to grip a lock of hair passed through the chamber, as illustrated in Figure 4. The sleeve is held with the jaw in its active or clamping position by 25 means of a collar 26 that is threaded, as illustrated at 21 on the body section I3, and being movable longitudinally of said section, abuts the sleeve to hold it and the clamping jaw in cooperative relation as shown in Figures 2 and 4. 30

The reduced portion I5 of the body section provides a chamber 28, and in this chamber is placed the stretcher section of the mandrel, said stretcher section being designated 29. Its outer surface has a contour corresponding to the 35 cylindrical form of .the body section, and it is laterally movable, or in other words, separable from the portion I5. For this purpose, at one end it rides upon an. outwardly projecting guide pin 30, and its other end may be slidably mounted 40 on .an inwardly extending pin 3| carried by a bracket 32 secured to the end of the body section. The stretcher section 29 is provided with recesses 33 through which the said pins pass, and coiled springs 34, placed in the recesses and 45 surrounding the pins, urge the stretcher section 29 outwardly. One end of this stretcher section l is preferably provided with a lip 35 that overlies the main portion of the body section I3, said seccated in opposition, and wedges 39, operating against these faces and movable longitudinally of the mandrel, serve to positively separate the cut-away portion and the stretcher section by moving the latter outwardly. These wedges may be carried by a stem 49 which extends through the end of the mandrel and is threaded to receive a pulling nut 4| that abuts the end face of the mandrel.

The stretcher section 29 is provided in its opposite sides with longitudinal grooves 42 constituting trackways for a carrier block 43 which has ribs lill on its inner sides that slidably engage in said grooves d2. This carrier block has outstanding spaced ears l5 between which is located the ear i6 of a hair-clamping plate 41 pivoted, as shown at 48, to said ears 45. The plate is transversely rounded to substantially correspond to the form of a lock wrapped upon the mandrel and this plate can be clamped on the hair, or as shown in Figure 2, by any suitable means, for example, a tension screw 49 threaded through a yoke 50 that overlies the plate and is mounted on the carrier.

For the purpose of additionally clamping the hair at its base and also securing the usual coverings in place, a ring is employed consisting of sections 5| hinged together at 52 and having their free ends adapted to be secured by a clamping bolt 53 (see Figure 3a).

In using the device, the base portion of a lock of hair, namely, that portion adjacent the scalp is passed through the entrance mouth I8 and lies against the inner face of the head I4 within the chamber E?. The sleeve 24 is now moved across the entrance mouth so that its end enters the groove 23 and the clamping jaw 25 will grip the hair by pressing it against the saidV inner face of the head (see Figure 2). The holding collar 26 is then threaded onto the main portion of the body section and by bearing against the adjacent end ofthe sleeve 24 holds the jaw in its active or clamping position. The exterior surface of the 'mandrel as a whole is now of substantially unbroken cylindrical form and the free portion of the lock is now wrapped snugly thereon in the usual manner, this coil extending over and around the cut-away portion I5 and the stretcher section 29. The carrier 43 is next moved forwardly and the clamping plate l1 pressed upon the free portion of the lock by the tension screw 49 so that the Yfree end portion of the hair is effectively secured.

The wedges 39'are`now drawn by turning the nut 4|V so as to cause the stretcher section 29 to move outwardly and this will obviously place additional tension on the coiled lock, securing that tightness which is so necessary to the best results. The usual treatment is then given, after which the covering, indicated at 54, is placed over the hair and the base of the lock is located in the seat 2| and is secured by the ring 5| placed in the groove 20, this ring also serving as a clamp for the covering and preventing the steam escaping from the interior of the covering 54 and injuring the adjacent portion of the scalp.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description,V and it will be understood that various changes in the size, shape, proportion, and minor details of construction maybe resorted to without departing from the spirit or sacriiicing any of the advantages of the invention.
