The casing comto the following detailed description taken in prises a curved face p ate and a back plate connection with the accompanying drawings, in 15, the former being in the shape of a trough which! to fit about a winding of hair on a curler' and Figure 1 is a perspective View of one form of the latter being shaped to hold the heating ele- 0 heater embodying the invention; ment firmly in placein the casing. The face Fig. 2 is a section taken in the directionfof plate 14 is bent over at its side edges to hold the the arrows along the line 2-2 in Fig. 1 back plate 15in place, and in order to closethe Fig. 3 is an end view of the heater, showing easing at its ends and to more securely retain the Same in Open po o the back plate, the ends of the face plate 14 are U5 4 is afront View thereof; i split to provide a plurality of fingers 16 which 1.10

sides of the casing and there is secured to each edge at 23 one of a pair of hingedly mounted arms 24 to each of which is secured, bymeans of screws 25, one of a pair of curved clamping elements 26 which are adapted'to 1 cooperate with the plate 14 to grip a winding of hair. Suitable means, as a spring 27, are preferably provided to normally maintain the clamping elements in gripping position. In order to permit the safe and easy manipulation of the device each of the arms carries an insulating block 28 which is ,secured to the plate by means of pins .29 and upon each of the blocks 29 there is secured by means of pins 30 a supplemental block 31 which is separated from the block 28 by suitable'means, such as the washers 32, to provide an air space 33 between the blocks 28 and 31.

This air space serves to augment the insulating propertiesof the blocks themselves and to sure against the transmission of any substantial amount of heat from the heating element to the fingers of the'o'perator. In the exemplified apparatus there are provided gripping members 34 hichare secured against the block 31.by meansl'of oneof the screws 36.

The exemplified device is particularly adapted for use, and in Fig. 5 -is shown as used, in connection with a curler 36 which-may be of the 'typeyexemplified in my copending application Serf'No. 311,994, filed October 12, 1328, which curleris adapted to be supported in a supporting clamp 3'7, which may be of the type exemplified in my copending application Ser. No. 323,057, filed December 1, 1928.

In practice the gripping members 34 ar grippedbetween the thumb and fo'refingerof an operator and pressed togetherso as to spread the clamping elements 26, and the unit is'lthen moved over a winding of hair on a curler, such, for example, as shown at 36, a pad or sheet ,38 .ofsuitable material being ordinarily interposed between the hair and surfaces of the members 14 and 26. After thelwaving operation is. completed the device is then readily removed by again pressing the gripping members 34 to- .ward each other; it being noted that the insulating blocks and the air space therebetween serve to prevent the gripping members from being heated, regardless of the duration of the heating.

The formcf heaterexempliiied in Figs, 6 to 9, inclusive, comprises a heating element 46 wound about a strip 41' of mica or other insulating materialand surrounded by a layer 42 of similar insulating material,.the whole being enclosed in acasing 43. The casing comprises a curved or trough-like face plate 44 and a back plate'45, the sides andends of the former being bent upwardly. about the side of the end edges of the latter. Lugs 46, extending over the ends of the .outer surface of the back plate, serve 'to hold the, parts of the casing securely togethen ing.

ment. mounting meanscomprises a pair of blocks and 51 held together by screws 52 and adapted to fit over one or the other of the conductors 49. To each edge of the supporting at 57 is a link 58, each set of links being pivotally connected to each other by a pin 59'carried on a transverse brace 60. This brace carries a sleeve 61, which is slidably mounted on a rod 62 extending outwardly from the back of the cas- At the end of the rod 62 is an insulating cap 63, and between the cap and the sleeve 61 is a coil-spring 64 which tends to maintain the sleeve in a depressed position and to'maintain the clamping elements 56 in a position adjacent the concave surface of the plate 44. In order to withdraw the sleeve and to spread the clamping elements, there is'secured to the sleeve by suitable means, as by a pin 65, or by being molded thereon, a manipulating element 66, which is constructed of insulating material, as is the cap 63, to protect the hands of an operator from the heat generated by the heating element. The forward side of the element 66 is preferably cut away somewhat, as indicated at 1 67, topermit the same tobe more easily gripped.

In order to protect the hands of the operator more effectively from the heat of the metallic parts of the unit and from steam or other hot gasesevolved during the hair-waving process, there is provided between the element 66 and the brace 66 a baiiie plate 68 of heat-insulated material, which, as exemplified, is mounted against a washer 69..

In practice, the operator places his palm over the cap 63 and, grasping the element 66, draws thesame, together with the sleeve 61, rearwardly along the rod 62 against the pressure of theunit isthen moved over a winding of hair and the element 66 released, whereupon the spring 64 will operate to move the clamping elements 56 against the winding. By this arrangement the chance of the heater unit slipping fromthe hands of the operator is minimized, and. the spreading and clamping. movements of the clamping elements is positively equalized, so that certainty of operation is combined with ease of manipulation.

The exemplified devices can be put in place and removed with the utmost case so thatannoyingdelays in the hair-waving process are avoided. They are sturdy and substantial, and at the same time economical of construcion, and satisfactorily perform all the uses to which a heater of this type is put.
