6 Claims. H (01. 132--36.1)

This invention relates to improvements in accessories used in connection with the permanent waving of hair and pertains particularly to an improved scalp protector or spacer. In the'operation ofpermanent waving, the hair is secured between two jaw members which are placed against the scalp and these jaw members are secured firmly together and. support a rotatable cylinder on which the hair is wound. In the device at present in use, the separable ends of ported that it is necessary for the operator to g,

employ both hands in taking out the roller.

The present invention has for its primary object to provide an improved coupling means between the hair gripping jaws whereby the said jaws of thespacer may be readily separated with one hand and an additional feature of the present device resides inthe novel construction of the supporting means for one end of the roller whereby such supporting means releases the roller automatically when the jaws are separated.

Another object of the invention is 'to provide an I improved spacer or hair securing clamp wherein the operating means for. securing the jaws in clamped relation or for releasing the jaws, is disposed at one side of the spacer in such a manner that the operator may hold the spacer between a thumb and finger of the hand and employ. another finger of the same hand to release the jaws and shift them into separated position, in which position the roller on which the .hair is' wound will be automatically released. The invention will be best'understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not to be confined to any strict conformity with the showing ofthe drawings but may be changed or modified .so long as such changes or modifications mark no material departure from the salientieatures of the invention as expressed in theappended claims.

In the drawing:

'Fig. 1 is a, view in top'plan of the protector embodying the present invention;

"Fig. 2 is a view in top plan of the device with the jaws separated and cylinder removed;

Fig. 3 is a view in end elevation of the device with a portion broken away;

Fig. 4 is an end view illustrating the separable trunnion bearing; and

Fig. 5 is a side view of the device at the pivoted ends of the jaws.

Referring now more particularly to the drawing, the numeral I generally designates the spacer device or clamp for the hair while the numeral 2 designates the cylinder which is rotatably mounted upon the spacer and upon which the hair is wound.

The spacer l comprises the two

usual jaw members

3 and 4, each of which consists of a flat strip of metal which has one edge and the top and bottom faces thereof covered by a rubber guard 5. I

In accordance with the present invention, one of the jaw members, for example, the jaw 3, is formed at one end with the laterally extending arm ,6, while the opposite jaw has the end adjacent the arm 6 laterally and obliquely extended to form the lever arm l. The end of the arm ii of the jaw 3'is pivotally attached to the jaw 4 at the inner endof the lever arm 1, as indicated at-S.

The jaws '3- and 4 at their opposite ends have upturned portions 9 and I0, respectively, which, when the jaws are in hairgripping relation, are brought into edge opposed relation, as shown in Figure 3, and as is also shown in this figure, one of these upturned portions is recessed at its top and adjacent the inner edge thereof to form a bearing H, while the adjacent or opposed upturned portion It] extends across and forms one side of the bearing. As is also clearly shown in this figure, one of the upstanding end portions is provided with a tongue [2 which extends into a receivingslot I3 in the opposing portion, thus forming an inter-locking connection between the free ends of the jaws which, when the jaws are closed, holds them in alined relation. One of the jaw'members, here illustrated as jaw 3, has pivotally attached thereto at the end remote from the arm 6, one end of a lever bar M, the other end of this bar being formed to provide the upstanding finger piece [5. Pivotally attached to the lever bar l4 adjacentthe free end thereof is one end of a link 16, the other end of this link being pivotally connected, as indicated at H, to the free end of the lever arm I.

When the

jaws

3 and 4 are in alined relation, the arm 1 of the jaw4, which jaw may be referred to as the movable jaw, extends across the adjacent end of the other or fixed jaw 3 and away from the latter, and the bar and link M-IB are in parallel relation with one another bar and link into this parallel relation, the jaws are firmly secured together and the upturned end portions 9 and II! are in the interlocked relation shown in Figure 3.

Formed integral with the edge of the arm 8 remote from the jaw 3, is an upstanding flange [3, the top edge of which is provided with a bearing nbtch Hi. This bearing notch is alined longi- 'tudinally of the device with the bearing recess ll, when the jaws are in gripping relation, and the bearing notch and recess are designed toreceive the trunnion-like ends 20 and 2i, respectively, of the cylinder 2. This cylinder is of the usual construction in that it comprises the elongated jaw portion 22 which is enlarged at each end and at one end is formed to provide the encircling ratchet 23 which is designed to be engaged by the spring pawl 24 which is supported upon one of the jaw members, preferably the movable jaw 4, as shown. The trunnion 2B which engages in the bearing notch 19, has formed integral therewith the key head 25, by which the turning of the cylinder is facilitated, and the cylinder also carries the usual pivotally attached finger 26, which secures the ends of the hair against the cylinder when starting the operation of winding the hair on the cylinder.

From the foregoing, it'will be readily apparent that in the present spacer device or scalp protector, the opening orclosing, action of the laws may be readily accomplished by the use of one hand and that when the jaws are opened by shifting the lever bar outwardly away from the adjacent body so as to effect the swinging ofthe other or movable jaw, away from the body 3, the bearing support for the end of the cylinder which is engaged by the spring pawl 24, will be opened or separated so that said end of the cylinder will be separated from the spring pawl and the cylinder may be lifted out without requiring that the operator manipulate the spring pawl to disengage it from the ratchet-23.

As previously stated, the devices which are at present in use are so constructed that both hands must be employed for removing the spring pawl engaged end of the cylinder as it is necessary to hold the cylinder with one hand and force the spring pawl free from the cylinder with the other hand. With the present device, this is not necessary, as the mere separation of the free or unconnected ends of the jaws simultaneously disengages the cylinder from the spring pawl.

The lever mechanism connecting the jaws together and consisting of the arm 6, bar l4 and link I6, is so designed that when the jaws are in closed position, they will be firmlysecured together as the link I8 and the lever bar M are then in aligned relation and are exerting the maximum force against the free end of the lever arm 1 necessary to hold the jaws tightly together in gripping relation. 7
