11 Claims.

This invention relates to eyelash curlers and is an improvement Yover my prior Patent #2,214,318, dated September 10, 1940 for Eyelash curler.

In my said prior patent, I have disclosed an eyelash curler in which most of the parts are made of sheet metal, the operating arms being of spring material. Furthermore, the construction of my prior patent has certain peculiar movements which are not as simple as those of the present invention, and said construction also requires that the fingers of the user be positioned in front of the eye during the curling operation with consequent partial obstruction of vision.

The present invention therefore contemplates the provision of a comparatively simple eyelash curler made substantially entirely of sheet metal and easily operated, but utilizing the spring backed rubber member shown in my prior patent.

The present invention further contemplates the provision of a curler having a comparatively. simple motion permitting the exertion of considerable pressure upon the cooperating jaws to eiect the curling operation quickly and without danger of cutting or severing thehairs of the eyelashes, the parts being suiciently yieldable inherently and by reason of theirform and mounting to take up any excess pressurewithinthe device without danger of injury or breakage.

The invention further contemplates the provision of means for adequately supporting the yieldable curling insert for one oi the jaws o f the device so that danger of cutting the hairs is minimized.

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

Fig. l is a side elevation of the curler showing in dash-dot lines the positions assumed by the lower jaw and its operating handle mechanism prior to the insertion of the eyelash between the jaws.

Fig. 2 is a front elevation of the same.

Fig. 3 is a top plan view of the lower jaw.

Fig. 4 is a vertical section of the jaws taken on the line 4 4 of Fig. 2. In the practical embodiment of the invention shown by way of example, the curler consists generally of the respective upper or fixed jaw Ill, the lower or movable jaw II, comparatively simple means to reciprocate the lower jaw toward and from the fixed jaw to press the eyelash therebetween, and a yieldable insert consisting of a spring backed strip of rubber removably arranged in the lower jaw and Of. th@ WPS. de"

(on. isz- 32) scribed and shown in my said prior patent. The xed jaw I0 constitutes the upper transverse member of the frame I2 of polygonal shape, said frame being formed integrally with the elongated f extension or arm I3 terminating at its lower end in the integral linger loop I4.

The parts I0, I2, I3 and I4 are all suitably stamped and bent from a single piece 0f comparatively thin sheet metal preferably spring metal, whereby the parts may yield to a certain extent when excess pressure is put thereupon so that the pressure upon the eyelash does not become excessive. The upper jaw therefore is y comparatively wide throughout the greater portion of its length so as to be comparatively rigid during the curling operation and under normal pressures, but at its extremities said upper orr fixed jaw is reduced in width at its juncture with the adjacent depending members I'I, I8 of the frame I2 to leave comparatively narrow connecting members as I9 between the ends of the upper jaw and the frame members I'I, I8, and formedl by the recesses I5, I6. At their lower ends the depending members I'I, I8 are joined by inclinedv members as 20, ZI to the lower transverse member 22 of the framev I2. The members II, I8, 20 and 2| are made narrower than the jaw IIJ,

whereby not only mayl the jaw yield relativelyv to the side members I1 and I8 by reason of the reduced connecting parts I9, but therentire frame may also yield to some extent relatively to its arm I3 under excess pressure put thereupon.

It will be noted, as best seen in Fig. 1, that the extension or arm I3 projects upwardly as at 23'v 'beyond the frame member 22 into the space 24 inside of the frame I2 to some extent. The projection 23 is provided with a longitudinally arranged guide slot 25. A similar slot 25' is provided in the arm I3 considerably below the slot 25, said slots being substantially parallel and in substantial alignment.A Outstanding at substantially right angles from the respective side edgesof thearm I3 are the reinforcing flangesA 26, 27 which aid in imparting rigidity to said arm and may also serve, as will be later explained in detail, to guide the lower jaw in its reciprocatory movement.

Said lower jaw is preferably somewhat narrower than the upper jaw, both being made con- Vex outwardly, however, in the customary manner. The` lower jaw is joined by the inclined frame members 28, 29 tothe lower transverse member 3Ito form a jaw frame, similar to the upper jaw frame I2, capable of slight distortion under excess pressures in the manner above described in connection with the frame I2. Depending from the cross member 38 of the lower jaw frame is the integral extension or arm 3|, whereby the lower jaw, its frame and said arm' may be stamped, pressed and bent from a single piece of comparatively thin spring sheet metal. The arm 3l is inserted between the flanges 26 and 21 of the arm I3 and in face to face relation with said arm and reciprocates vertically therebetween as viewed in Figs. 1 and 2 to carry the lower jaw toward and from the upper jaw. To constrain the lower jaw to move in the desired straight line path, the extension 3i carries the spaced pins 32 and 33 passing through the respective slots 25 and 25' of the arm I3. Said pins are each headed as shown to prevent separation of the arms I3 and 3I from each other.

As has been hereinbefore indicated, suitable means are provided to move the lower jaw. As shown, said means comprises the bell-crank-lever 35, preferably made of thin spring sheet metal and provided at one end with the finger loop 35. Said lever is pivotally supported as by means of the pivotl pin 31 passing through the supporting lug 38 outstanding at substantially right angles from an edge of the arm I3. The outer end of said lug is spaced a suiiicient distance from the arms I3 and 3l to provide a crank arm 39 on the bell-crank-lever of sufficient length to impart the desired stroke to the movable arm 3l operating the lower jaw.

Outstanding integrally from an edge of said arm 3l and adjacent to and substantially parallel to the lug 38 is the apertured lug 40 provided with the opening or slot 4I into which is inserted the operating end part 42 bent from the lever portion 39. Said end part 42l is preferably of reduced width compared to that of the crank arm 39, but is nevertheless of sufficient strength to impart the required pressure to the lug 40 as the bell-crank-lever 35 is swung about its pivot in the proper direction to press the lower jaw I I against the upper jaw I 8. It will be noted that the iinger loops I4 and 36 are below the eye and do not interfere with vision during the curling operation and that the user can also see through the interior of the frames of the jaws.

The lower jaw is provided with a series of comparatively short, spaced and inwardly directed lugs 45 at substantially right angles to the face of said jaw and on which the removable yieldable member 48 forming part of the lowerV jaw may rest. Said member 48 consists of the rubber strip 41 which is suitably bonded with and thereby secured to the metallic backing strip 48 in a known manner. The strip 48 is preferably of thin spring metal and quite iiexible so that the parts 41 and 48 of said member 4B comprise substantially one integral piece bendable as a unit for easy insertion into the jaw -when required. It will be noted that the metallic spring strip 48 is arranged with its face substantially in contact with the inner face of the movable jaw II (Fig. 4). The end parts of the jaw II are bent into the form shown in Fig. 3 first inwardly away from the face of the jaw and then parallel thereto to form the bent ends 49 on the jaws II and to provide an end space or groove as 5D for the reception of the respective end parts of the member 4B. To prevent the backing strip 48 from rising out of its proper position when the upper jaw I0 presses on the rubber portion 41 of the insert by the squeezing action of the jaw on the rubber strip, a short lug 5I projects inwardly from the top edge of the jaw II and overhangs said strip 48 without, however, overhanging the rubber strip or interfering with the movement of the jaw I8. I have found that no means other than the lugs 45, 49 and 5I on the jaws II are needed to maintain the removable member 48 in its proper place in the jaw II, and that even the lug 5I may be dispensed with if desired.

The member 46 being arranged in the lower jaw, its ends being in the spaces 58 and the metallic strip 48 being against the face of the jaw and the upper edge of said metallic strip being underneath the lug5I, the device is ready for operation. It will be noted that it is comparatively easy for unskilled persons to replace the member 46 when worn, cut or when it becomes aged and not suiiciently resilient, the spring backing 48 making the handling of the member and its manipulation a simple matter. The bell-crank-lever having been moved to the dash-dot position of Fig. 1 to space the jaws I8 and I I apart, the curler is moved to the front of the eye to arrange the eyelash between the jaws, and the finger loops I4 and 36 then pressed toward each other. The crank arm 39 is thereby vrotated in a clockwise direction as viewed in Fig.

1, the end 42 pressing the lug 4I upwardly and consequently moving the arm 3| and the jaw II upwardly until the lower edge of the jaw I0 is imbedded in the rubber strip 41 thereby to curl the eyelash. The rubber strip yields during the last part of the movement, but if the operator exerts greater force upon the finger loops sufcient to overcome the resistance of the jaws and their frames, the jaw I8 may yield at the reduced parts I9 thereof and the frame for the jaw II may also yield somewhat, while the spring arms I3, and 3| may be bent somewhat toward each other. This take-up or yielding action is sufcient to prevent the eyelash from being cut or injured under excessive pressures. By separating the finger loops I4 and 35, the eyelash is released, the arm 3| being guided in its movement by 'the pins 32 and 33 moving in the slots 25', 25 as well as by the flanges 26, 21 engaging the edges of the arm, if desired. There is no necessity for any other guiding means and hence the frame for the jaw I'I is completely free of the members I1 and I8 of the frame I2 and is not prevented from yielding relatively thereto under excessr pressures.

It will be seen that I have provided a simple structure designed for economical manufacture and capable of performing the purposes intended.

While I have shown and described a specific embodiment of the invention, I do not intend to be understood as limiting myself thereto, but intend to claim the invention as broadly as may be permitted by the state of prior art and the scope of the appended claims.
