Application 'filed August 27, 191.9. Serial No. 320,294.

To all @zi/1.0m it' may comi-cm Be it known that l, Anreise lonnnrzr, a citizen of Spain, and a resident oi G Avenue Friedland, Faris, France, ha ve invented new and useful Hair-Grulin.; irons, ot which the following is a specification.

The present invention relates to a hair curling iron consisting ol two arms movable in relation to one another', characterized by the fact that these arms carry combs and a toothed core or former, the curling ot the hair engaged in the tee-th oit the combs and former enclosed between said combs, being obtained by relative movement of these two members, that is to say by deformation ol the originally straight lock ot hair.

The annexed drawings represent by way oit example two, forms or construction:

Figures '1, 2, 3, e and 5 represent a first forni of construction-` Figure l is aside elevation of the instrument in the closed position, the upper and lower shields being in section upon their longitudinal axes;

Figure 2 is a side elevation oi the instrument -in the open position, the upper and lower shields being in section upon their longitudinal axes.

Fig. 3 is 'a plan View corresponding to Figure l, the upper shield beingvremoved; the dotted lines indicate the deformation of the lock ot hair by displacementl of the core or former from left to right.

Figure 4c is a View oit' the instrument seen from below, the lower shield being removed.

Figure 5 is a section on `line 5-'5 of Fig ure '1.

Figures 6, 7 and 8 represent a second form of construction;

Figure 6 is an elevation in longitudinal section of the instrument in the open position.

Figure 7 is a horizontal section on line 7-7 of Figure 6, the cover enclosing the mechanism for operating the combs being removed. .Y Y

Figure 8 is a vertical cross section of the instrument in the closed position.

According to the iirst 'orrn or construction, ythe same arm carries twolixed sidecombs, between which is placed a movable core or former; the reciprocating movement oit' the core is'obtained by hand by actuating one or other of the levers provided for this purpose, and the release of the hair .from

the teeth oli the comb and from the grooves on the core is operated by the raising of the bars parallel to the side combs, kproduced by the opening' of the instrument.

The curling iron comprises two arms c and ZJ jointed together atA the point c. The arm av consists of a plate (Z with two rightangled flanges e which are notched at so as to form side-combs. rlhis plate is also provided `with an elongated slot g which serves as guide to the movable core or former 71. The latter is ot' semi-cylindrical shape and provided on the convex upper side with grooves i. corresponding to the notches j in the side combs; on its lower side it carries two lugs i having rebates in which the plate d engages.

rihe displacement or' the core 7b is obtained by a connecting rod j 'pivoted at one end upon the lug e and -at the other upon a crank 7c integral with a pinion Z, the spindle m of which is fixed upon the plate d. The rotation of the pinion Z is obtained in one or the other direction by the movement of one or other of the levers n and 0 carrying respectively Y externally and internally toothed segments; the axisoit rotation o common to these two levers is fixed to the plate d.'

Upon the spindles g vand g journaled on the plate Z are riveted short cranks r and r at the extremities or which are pivoted metal bars s parallel to the side-combs and forming coupling rods.

The axis Q is integral with 'a cranlr t upon .which is pivotally connected a rod u, of

which the other extremity is connected to arm o so that the motion of opening the arms a ZJ produces the raising of the bars s.

ln order to curve 'or wave a loclrofhair, the method of operation is as follows: The instrument having been rst heated to a suitable temperature, the arms a o are separated and the lool; of hair which it is intended to curl is introduced between them; the side bars s Vbeing raised, the hair can then uniformly spread `over the whole length of the instrument. By bringing togetherl the two arms, the bars s are loweredto 'clear the side combs; the hair then engages linthe teeth of the side combs and in the grooves ,of the former, Vthis being the Vposition shown in full lines in Figure 3. By pressure upon the lower lever fn, the core or former is displaced irom lett to right, whereby the lock ol hair is distorted along the dotted lines y which produces a further distortion ot' the lock ot hair by movement of the corey or former from right to lett. This same succession ot operations is thus repeated as many times as necessary.

According tothe second form ot construc- 1 tion. one ofthe arms carries the side combs andthe other the movable core; the reciprocarory movement of the latter is controlled automatically by the closing of the instrument and the release of the hair from the combs is effected by the withdrawal of the said combs into the interior of the instrument.

The same reference letters indicate the same parts as in the first construction, the new` parts being designated by figures.

, The lower arm a, consisting of a semicylinder, carries internally two movable combs 1 each forming a portion of a cylinder. These combs 1 are guidedA in their displacements by pins or screws 2 passing into slots 3 at their extremities. lEach comb comprises two inclined ramps 4 in which engage two pins 5 carried by a plate 6 movable at the bottom of thearm a; this plate 6 is guided by pins or screws 7 passing into slots 8 aligned along the centre line, and receives a reciprocating movement from a connecting rod 9, the other end of which is pivoted upon the arm b.

A semi-cylindrical cover 10, secured by screws upon the kbody of the arm a encloses the mechanism for elevating the combs.

The upper arm Z) comprises internally two longitudinal webs 11 which serve as slides i' for the toothed former h supported by two transverse lugs 'i and t.

The former lzy receives by means ot a rod l2, a connecting rod 13 and a crank 14, a reciprocating movement from a mechanism contained in acasing 15 and hereafter described. Y

This mechanism is arranged in such a way that at the end of the closin movementof the instrument,'the core or ormer receives a motion of translation in one direction,'and that atthe succeeding closure itreceives a movement of the same extent in the opposite direct-ion which restores it to its original position.

The mechanism comprises a rod 16 guided at the bottom ofthe casing 15 and operated by means of a connecting rod 17 during the opening and closing of the instrument. This rod 16 carries a lug 17 which serves to operate a crank 18 keyed upon a spindle 19 j ournaled in the casing 15 and upon a crossbar 20 secured in the casing. A pin 18 limits the rotation of the spindle 19 in Vthe direction of unwinding of a spiral spring 21 fixed on this spindle and having its other end attached to the casing 15. A ratchet wheel 22 is also iXed on the spindle, the ratchet 23 loose upon the spindle 19. A spring 25 orming a stop allows rotation of the wheel 24 in one direction only. A pinion 26 keyed on a shaft 27 meshes with the toothed wheel 24, and on this shaft 27 is fixed the crank 14.

A coiled spring 28, acting on the guided rod 16 causes automatically the opening of the instrument. Y

Let it be supposed that the instrument is in the open position indicated in Figure 1; `in this position the side combs 1 are lowered, the core or former h at the end of its movement towards the right and the spiral spring 21 unwound. On closing t-he instrument, the plate 6 is displaced from left to right and causes the raising oit the combs by the lugs 5 engaged inthe inclined ramps 4; at the same time the Guided rod 16 moves from left to right carrying the crank 18 in its movement. This rotation causes the'winding up et the spiral spring 21, whilst the toothedA wheel 24 remains stationary, the teeth of the ratchet wheel being turnedrin such a way that in this direction of rotation the ratchet 23 slips over the teeth of the wheel 22. At`

the end of the stroke of the guided rod 16 the crank 18 escapes from the lug 17, The spindle 19 and the ratchet wheel revolve in the direction of the arrow carrying with them the toothed wheel 24 which is connected to the ratchet wheel 22 by theratchet 23. This rotationfproduces at the same time that Volf" the pinion 26 and of the crank 14 fixed on the same spindle. `The gear-ratio of the toothed wheel `24 and pinion 26 is such that for the amount of the an ular movement of the crank 18the cran 14 makes a half-turn; in this way the former l1. which Awas at the end of its stroke to the right, travels from right to left and comes to the left end of its stroke, while the crank 1,8 has "come back to its original position against the lug 18.

Upon openm the instrument, the side combs 1 drop, te guide rod 16 moves from right to left bringing the lug 17 kagain into engagement with the crank 18, which sets the mechanism o nce more in position to operate; at the next closure, the former h will receive a movementfrom left to right. 1

The operation of the curling iron in accordance with this second construction is similar to that of the instrument previously described, but its use is very much simplified, because after having heated-the iron it is only necessary to spread the hair uniicrinly over the whole length of the lower Vbeing mountedv upon a toothed wheel 24 y ico arm and to bring the two arms together in order to obtain the curling or undulating effect. The instrument is opened and moved by a distance equal to its width 'along the lock ot hair and re-closed; in this way the same succession of operations are repeated as often as necessary.

It will be evident that the invention is not limited to the terms ot construction and the details which have been described. Thus, for example, these instruments might be constructed tor electrical, gas, alcohol or gasoline heating, and any suitable mechanical, pneumatic or electrical operation might be employed for raising the side bars or combs and reciprocating the core or former.

Lastly, a curlinginstrument in accordance with the invention can be constructed with several cores or tormers, and several combs arranged parallel to one another so as to allow of curling a complete length of hair at one operation.
