EYELASH CURLER Filed Jan. 12, 1940 lNvENToR Hannan Bernstem ATTO NEY Patented Sept. 10, 1940 UNITED STATES PATENT OFFICE 2,214,318 EYELASH ofURLEn Herman Bernstein, Brooklyn, N. Application January 12, 1340, Serial No. 313,516 ze ciaims. (o1. 13a-32) i mechanism is subject to considerable wear and frequently does not permit the user to exert sufficient pressure on the jaws to perform the curling operation effectively. Furthermore, the.

rubber member used in one of the jaws changes in time in shape and length and otherwise deteriorates and needs to be replaced, but the operation of replacement is frequently beyond the skill of the user.

My invention therefore contemplates among other things, the provision of a simple and efficient curler adapted to be leconomically producedy from sheet metal and to be locked into compact form when not in use, while designed to be readily unlocked when it is to be used, and when s o unlocked, being fully under the control of the user to exert heavy or light pressure over a wide range on the eyelash. My invention further contemplates the provision of arcuate cooperating members each 'integrally'formed at the free end of a spring arm and movable away from each other in a substantially straight line path under the spring action of the arms without the necessity for linkage, pivots, guides or other mechanism, said members being movable toward each other in a substantially straight line path by force exerted directly thereupon by a hand lever whereby not only. is the curling pressure accurately controlled but connecting linkage and other operating meanssubjected to substantial wear, are eliml,'Myfinvention further contemplates the provisionof simple means for so supporting the rubber member' that it may quickly and easily berremoved and replaced by unskilled persons and without the necessity for the use of channels or equivalent devices which have the tendency to'bend the hairs abruptly and frequently cause to the sides of the member and higher at .the

front than at the back thereof whereby the curling action is A quickly initiated by said surface and the curling operation more quickly and easily completed.

, The various objects of the invention will be clear kfrom the description which follows and from the drawing, in which, f

Fig. 1 is a top plan view of my improved curler as it appears in its locked or inoperative position.

Fig. 2 is a side elevation of the same.

' Fig. 3 is a rear or end elevation of the same.

Fig. 4 is a vertical section of the same as it appears unlocked and the lever arranged in position for operation of the curling members.

Fig. 5 is a vertical section ofa modified form ofthe yieldable member. l

lIn the practical embodiment of my invention which I have shown by way of example, a pair of sheet metal spring arms I and II each preferably though not necessarily of a single piece of material are provided, the, arm I0 carrying the rigid curling member I2 at its fron-t end, and the arm II carrying the support I3 for the resilient and yieldable cooperating curling member I4. Said arms are provided with diverging portions, spaced apart at their rear end parts sufliciently to maintain the' adjacent edges of the members l2 and I4 in substantial spaced relation and thereby to permit the easy insertion lof the eyelash between said members when the curler is unlocked ready for operation.

The front end portion I of the arm I0 is bent at an obtuse angle Vto theremainder of said arm and is suitably and permanently secured (as by means of the rivets or the like I'I) to the adjacent similarly bent'portion I6 of the arm II in thereofris the pin 2| formed with an enlarged head' 22, a short cylindrical part 23 fitted into the perforation' and an elongated shank terminating'in the flattened loop 24 passing through the preferably circular opening 25 of the arm I0. Saidloop 24 is cut away as at 26 to permit the crossk bar 21 of the operating lever 28 to be inserted into `the loop and to be normally held in lengagement with the upper end part 2S thereof under the spring action of the armslll'and II, which tend to spread apart or open up'and thereby lconstitute flat springs. Said cross bar 2Iis arranged between and separates the slots 30 .and 3|. the rear -edge of the lever 28, being arranged midway between the side edges of said lever, while the slot 3I is similarly arranged between saidside 1 edges but forwardly of the cross bar. One side arm of the loop 24 therefore liesin the slot 3Iland the other in the slot 3| The slot 30 extends forwardly from y of the cross bar uponthe pinZHI.

An upwardly projecting cam or humpr32 is integrally formed in the arm III just forwardly of the opening 25 and is arranged to engage the convex rear end portion of the lever 28 when said lever has first been rotated into vthe yposition of Fig. 4 and is then swung in the'direc'tion ofthe arrow of said figure about the cross bar 21 as a pivot. ing the thumb of the hand in the loop, Vresting one or more ngers on the lever, and pressingl the thumb and fingers together' .against .the spring action of the arms I) andI I. The cross bar 21 is thereby raised, the loopl 24 drawn upwardly through the opening 25 and the 'arms I0 and II as well as the members I2 and I4 carried thereby forced toward vjeaeh other to perform the curling` operation.

It fwill be understood that while I have hereinbefore referred to 'the arms Ill andII as spring arms, one of said arms may `if `desired be made comparatively rigid and'unyielding as compared to the other. In other words, it" is not necessary that lboth arms become distorted when the mem.- bers I2 and i3 are vmovedtoward each other, it being suiicient if one of 'thearms is capable of spring action andconsequentmovement'relatively to the other. In vsuch case, one of the arms is made of comparativelyA thin spring Inaterial and the other made of comparatively thick and `rigid material, it being substantiallyimmaterial which arm is 4 the spring arm. v

Normally, the parts are in thepositions'shown in Figs. 1, 2, andy 3 in `which the lever 28 has been rotated into an upside down position rela- 5 tively to that shown in Fig. 4, andthebent front end 3K3 thereof has been vinsertedfinto and locked in the slotv I9 of vthe] arm I0.; In this position,` the members I2 andlll are closed together, the rear end edge 34 of the lever-28 being sufficiently below the 'top 2S of the loop 24fto have forced the arms It and I t together by fthe pressureof said end 34 upon thatpartbfthearm III to the right ofthe crossbar 21er `by the upward pullA To move the lever from the position of'Fig. 4 to that of Figs. l, 2 'and' 3,1the end 33 of the lever is rotated in a horizontal.plane as 'viewed in Fig. 4 until it is arranged fon "the right hand side of the loop (24 as shown by`the dash-dot lines of Fig. 4, the cross' bar 21 during 'such swinging movement causing the loop 24 'and 4the pin `2I to'rotate about th'exaxis of'theipin through an angle of 180,". The end 331 isthen swun'gin a vertical .plane to the left and vdownwardly'about the bar 2'I as al pivot into its'locke'd position, the

convex rear part of the'lever acting as aerank to exert upward force upon"- the lpin 2I and downward force on the arm III and thereby to movethe Vpin and the arm I I upwardly relatively to `the arm IB. Owing 'to thejtenden'cy ofv the arms I and II to move apart,upward'force is exerted upon the end i34 of the 'lever ftending to rotate it in a counter-clockwisev 'direction about the bar 21 and thereby holding the 'end 33 down in the slot I9.

The curler in this position` iszltncked'to occupy littleV space for carrying about as `in*a"han`d]oag or to lbe put away'until it is ready for use. To unlockthe parts for operation, the above described lmovements are reversed. That' is; the lever end 33 is raised out 'of the slot I`9`, then swung in a vertical plane to the 'dash-dot vline position thereof shown in 4, permitting fthe arms I'II 'andVI I to spread apart' under fthe spring action thereof and the pin 2l-5to ibe* lowered Preferably the lever is so swung by insert-"- relatively to the arm I0, whereafter the lever end 33 is swung in a horizontal plane to the fullline position of the leverv in Fig. 4 simultaneously rotating the pin 2l through an angle of 180,J withthe members FI 2 and jI4 ready for the reception of the eyelash, and the leverready -for the depression thereof to force the curling members together.

-The upper curling member I2 is preferably formed integrally with the arm I 0 being joined to the-.rearend'of said arm by the substantially.

right angle bend 35 and being of sufficient width,

greater than that of the arm I, to properly engage the entire eyelash of the user. Said member is ymade arcuate or curved for that purpose 1as is customary. Its lowerV edge 36 Vis rounded y'to obtain the desired vcurling 'action without danger of cutting or breaking the eyelash hairs. The edge 36 may be notched at its ends 'as "at 31 to make said edge of -the same lengthbetween notches as the length of ythe member I4, while the material 38 of the mem--` 'ber' I2 above the notch is preferably bent for wardly to better t the eye and to provide rounded end portions "on said member. p The lower or support member I3 is of substantially lesser height than that of 4the member I2, but is similarly made of corresponding arcuate or curved form `being joined to the arm I'I 'by thelbend 39. Each of the free fend por-- tions 400i the member I3 is bent forwardly and then `parallel to the main portion of said mem-` ber to form a bottomless groove asj4I at each end of fthe member for the reception of the respective ends lof theV vyieldable member I4. (Fig. 1); That part of the arm II just in 'front of the member I3 andthe bend '39 serves as the bottom "support forsaid member I4. If desired, additional'integral bottom supports may be provided by the "spaced lugs '42 `extending forwardly and integrallyfrom the lower edge ofthe member I3 and at substantially right angles thereto. An Vimportant feature of the` present invention is the removable and replaceable yieldable member I'4 which eliminates the necessity for the use of 'channels or their equivalents in either of the curling members.

Saidmem'ber I4 Y comprises l,the elongated rubf,

ber member 43 and a metallic` spring backing plate I4 which is :initially bent slightly into a. generally arcuate shape and permanently secured asv by suitable adhesive to the front wall 45 of said member '43.Y The initial curvature of the plate is'preferably less than that of themember I3, that is on a curve'of greater radius. vSince the manner of so securing rubber to metal Vis well known, no further description 'thereof is deemed necessary. It will -be noted that the top surface 46 of the rubber member 43 is bevelled or yin other -words,arranged at angles other than right angles tothe front wall 45 and the parallel back wallf41 ofthe member 43, :and that the bottom wall v4 8 is preferably atfright angles to the walls 45 and 41. Due to the inclination of the top wall, the eyelash vhairs are given an initial upward inclination` as Vthe curling lmembers are lbrought together and evenbefore any' pressure is applied thereto'. Consequentlyno sharp or abrupt bends or :crim'ps are formed'inth-e hairs and `no cutting or breaking thereof is possible.

'I'hek curling member I4 -is readily arranged on its 'support I3 by merely kplacing the bottom wall on''tlie'horizontalpart -42 with the end of said member including the ends of plate 44 in :the -re- 'spective grooves 4 IVVA and the 'rear wall V'41 iniconthe member I3 when the ends of the member I4 are inserted into the grooves 4I, the tendency of the plate and of the rubber member 43 to straighten out serves to maintain the entire member I4 in position on its support. However, the member I4 may be additionally held on its support if desired, by means of the integral lugs 49 extending downwardly from the plate and inserted into suitable spaced perforations 50 in the arm portion. Preferably, the rear wall 41 of the rubber member is of the same height as the member I3 and does not project thereabove when the member I4 is in place, but the plate 44 is higher to provide the bevelled surface 46.

As shown in Fig. 5, separate pins as 5I may be secured to the front 'face of the plate 44, as by rivets 52, said pins entering the spaced perforations 53.

When the edge 36 of the curling member I2 is forced down on to the top wall 46 of the rubber member, the eyelash hairs are curled, the time of curling being hastened on greater pressure applied by forcing said edge 36 into the rubber member to the desired extent. Such pressure merely distorts the rubber member, stretching the front upper part thereof and compressing the remainder. Should the member I4 become worn or cut, or should it otherwise deteriorate, it is easily lifted out of the grooves 4I, the lugs 49 or 5i being at the same time removed from the perforations 5I). A new member I4 is then readily inserted into Said grooves by unskilled persons, the plate 44 thereof being of material aid for that purpose because of its smoothness and because it slides easily along the metal surfaces of the walls of the grooves` The entire member I4 is easily handled in its pre-formed shape imparted thereto by the spring plate and can easily be bent into its nal form against the spring action of the plate, and maintained in that form by said plate after the plate has been inserted into the grooves 4I.

It will thus be seen that I have provided a simple curler well designed for the purposes for which it is intended and to meet the requirements of practical use.
