Application An ustvlc, 19%,SerielNc-J1DAQ5 This.inrentiomrelates tolaxhaincurlera Itis :a,primary objecthof, theinventionto pro: vide a onemiecespring and guardof, such construction ,1 asv to. preclude catching. ofmthehair; in the anglelbetween the spring and guardii. As will be explained more, fully, hereinafter, this ad; vantage, is achieved by offsetting the curve offth'e gnardc. froml that of the l spring to substantially eliminate anyiangleinvwhichithe hair may catch.

It ,is-,a further object of the invention toprovide'means whereby a single screw connects the winding, arm tothe, handle and connects the handleto the mandrel in one operation;

In, the drawings:

The improved, curler comprises a forming bar or" mandrel 5; which,- solely for reduction in weight, is desirably madewith a cavity at 6. Externally; thebar isentirely cylindricalexcept for an annular-channel at I which receives: a screw 8 forrrotatively positioning-the knobs-on the cIQSedendpfthebar; It will be noted that the knob 9 'has-a-- radial bore-I B i which is sbigger than the threaded shank of screw 8 -1 and is counterbored at-lI to receive the head' of; the screw: The knob has-asocket at -12 forxthexend of themandrel and F a recess: I3 as best Sh0W1L'iIl Fig: 3 which is arcuateandopensintothe socket l2 and receives the end of the. spring 1armr: I5. Thisarm is desirably arcuate imcross sectionto conform to the-- outer .surfaceeof; thegm zndr l- It is desirably tapped so: i that: the; SSJIBWs- 87 is threaded therein. Since-:such 1 SQIEW 2' iszinot; in threaded connectionwith; the zknob; the tightening of the screw draws :the aarmil 5-;snuelr eainst the interio-r'surface ofithe; knob. At;the;same

time, the-inwardly projecting; end-I of;the ,-screw penetrates the annular channel 'I' of the: mandrel to anchor the-knob-rotatably;one-the mandrelt That portion ofithe spring-arm. Ifit-whichlis arcuate in cross section desirably terminates .at T

Whilethe side portions'ofthe arm 'are folded backwardly upon themselves-to provide-thelever I9, a central tongue 22; struck-from thecenter of the blank from which the piece is formed, continncs: "lon itudinally-of the mandrel" 51beyond the 'reversely-turned"bends I 8-; The tongue 2? isalso reversely bent at' 23-; but desirably'on'a curveiof larger radius than thatwhich provides 1 the=bends at- I81; Thus,-ythe reverselyextending guard 24 at-"the endofthistongue is spaced cut wardly from lever 19:; The'factthat-the bends at l 8 and 2 3" are ofiset-longitudinally of the mandrel, and the consequent disposition of the guard zd -outside-of the-bends at I8 makes it virtually impossible for-hair'to catch in the appliance-duringuse:

Without the guard member- 24, looks and strands of hair other: than those upon which the curler is operating tend to become entangled with the forming lever-I Sonwiththe 'lockrof hair engaged-:by such lever; with the result. thatthe rotative-movement ofithe former and knohis arrested, and "pain may be caused to the patient. The guard M deflectsaallhair other thanvthat uponwhich the =iorming, lever I9 ,is operative, thereby enabling the one look of; hair; engaged b'y-lever I 9'-to be aWOllIld smoothlynpomthe mandrel;

Icclaimrz l'zlAvhairycurlercomprising a mandrel anda part.- provided with a -,=rotatablc, mountin on said mandreliand integrally including ags pring arm portion and a guard portion, each of saidportions being reversely bent upon itself, the reverse bend of the guard portion being ofiset longitudinally of the mandrel beyond the reverse bend of the spring arm portion, and said guard portion including a terminal part extending back over the spring arm portion in partial lapping relation thereto.

2. As a new article of manufacture, a onepiece spring arm and guard for a hair curler comprising a strip having a longitudinally extending tongue struck from a portion of the strip intermediate its sides and ends, side portions of said strip being reversely bent upon themselves at the base of the tongue and the said tongue continuing beyond the reverse bend of said side portions and having a reverse bend of its own at a point offset from the bend of said side portions, and further having a terminal portion extending longitudinally of the strip in spaced relation to the side portions thereof.

3. The device of claim 2 in which the reverse bend of the tongue is of larger radius than the reverse bend of said side portions.

4. As a new article of manufacture, a combinationspring arm and guard member for use in a hair curler, said member comprising a strip having a substantially rectilinear portion and having beyond said portion an elongated slot intermediate its side portions and ends, each of said side portions being provided with a reverse bend at one end of said slot and thence extending in substantial parallelism and in spaced relation to the substantially rectilinear portion of the strip, said strip having an integral tongue extending from its said rectilinear portionat one end of the slot beyond said bends, said tongue being provided with a reverse bend and a terminal guard portion spaced outwardly from the rectilinear portion and side portions of said strip and extending longitudinally of the strip in a rearward direction from the reverse bend of said tongue.

5. The device of claim 4 in combination with a mandrel along which said strip extends and a knob rotatable upon the mandrel and provided with a screw connecting the knob with said strip for the rotation of its said rectilinear portion about the mandrel, the said strip having a terminal with a tapped opening in which said screw is threaded. v

6. The combination with a mandrel having an annular channel near one end, of a knob having a socket in which the channeled end of the mandrel is disposed, said knob having a recess opening into said socket and a substantially radial hole opening into the recess, a spring arm extending longitudinally of the mandrel and having an anchorage portion in the recess between the mandrel and the knob, said anchorage portion being provided with a tapped hole, and an anchorage screw extending through the radial hole of therknob into the tapped hole of the anchorage portion of said spring arm and in threaded connection with said arm, said screw having a terminal portion projecting beyond said arm into the channel of the mandrel for rotatably positioning the knob on the mandrel.

'7. A hair curling device comprising a mandrel, a collar member rotatably mounted at one end of the mandrel, a winding member fixed to the collar member, said winding me r Comprising an arm member secured at one end to the collar member and extending parallel to the mandrel and reversely bent at its free end to provide a guard member, the said arm member being provided intermediate its ends with a spring clip member integral at one end with the arm member at a point adjacent the guard member and extending in parallel and spaced relation to the arm member to provide a hair receiving opening, the free end portion of the spring clip member being provided with a reversely curved offset portion which resiliently engages the arm member whereby a tress of hair may be removably received between the arm and clip members.

8.

9. As a new article of manufacture, a onepiece spring arm and guard for a hair curler comprising a strip having a longitudinally extending tongue struck from a portion of the strip intermediate its sides and ends, side portions of said strip being reversely bent upon themselves at the base of the tongue and the said tongue continuing beyond the reverse bend of said side portions and having a reverse bend of its own at a point offset from the bend of said side portions.
