HAIR-UNDULATING 'IONGS.

Application filed December 8, 1926, Serial No. 153,434,.and in Norway December 12, 1925.

My invention relates to hair undulating tongs of that kind in which the hair is grasped between gutter-like members, of which one has a convex outer surface and the other a concave inner surface. My improvements in hair undulating tongs of this type relates partly to means for holding the hair only in the middle portion of the said gutter-like members so that the adjacent hair portions hang freely between the side portions of the said two gutters, and partly to a needle arrangement for moving the freely hanging hair portions in the longitudinal direction of the gutters all as described hereinafter.

The invention is illustrated diagrama-tical-- ly and by way of example on the accompanying drawing on which Figure 1 is a perspective illustration of hair undulating tongs designed according to this invention; Figure 2 is a side View of a modification; Figure is a longitudinal section through the parts shown in the upper half of the righthand portion of Fig. 2 this Fig. (3) being drawn to an enlarged scale and turned by an angle of ninety degrees relativelyto' said portion of Fig. 2; and Figures 4 and 5 are cross-sections through the undulating members of the tongs, these members being shown in two positions, all as fully described hereinafter.

Referring to 1, 1 and 3 denote two gutter-like undulating members, and 2 and 4 denote grips firmly connected with said members so as to form tongs, as shown. The member or gutter 3 fits into the member or gutter 1, but the radius of curvature of its convex surface is alittle shorter than the ra dius of curvature of the concave surface of the gutter 1. The difference is, however, only slight. At any rate, the respective surfaces contact with each other intimately only at their middle lines, whereas there is no rims of the gutters extend somewhat outwardly like narrow flanges; the upper face of the rims or flanges of the gutter 1 is convex in cross-section, as shown at 5, and the lower face of the rims ,or flanges 8 of the gutter 3 is concave in cross section, as shown at 6, and slots 7 provided in said convex rimsof flanges can receive needles projecting downwardly from the legs of a U- shaped bow 9 located in guide ways extending along in the rims or flanges 8. The bow 9 can be shifted in said guide-ways. The needles 10 extend downwardly through slots The communicating with the said guide-ways and I terminating at the grooves 6 so that the need.es can be moved along in these grooves.

D If the tongs are to be used, the hair is held fast on the bottom of the gutter 1 between this and the adjacent portion of the lower surface of the gutter 3 so that it passes freely through between the flanges of the two gutters and. can be shifted therebetween in their longitudinal direction. i

The tongs may be heated electrically by means of heating bodies enclosed in suitable parts of the tongs.

In the modification shown in Fig. 2, the

gutters

11 and 12 areaflixed to the arms '14 and 15 of double-armed levers jointed to one another by a pivot 13 and the

other arms

26 and 17 of which form the grips of the ongs.

Thev gutter 11 carries a slide 18 which can be shifted along said gutter and is provided with two rows of downwardly extending pins 19, as shown in Figs. 4- and 5. The bottom of the gutter 11 is slotted and contains in its slot a ledge 20 which can be moved out wardlypand inwardly, aswill appear from a comparison of the Figs. 1 and 5. The means for thus moving the ledge 20 may be of any desired kind. In the example shown, a cam 21 18 secured to a shaft 22 supported in cross walls 23 of the gutter, and cranked at its outer end 24 where a grip 25.is attached to this end whereby the shaft 22 and the cam 21 can be turned/ The shaft 22 passes also through sleeves/28 connected firmly with the slide 18, andspaclug tubes 27 are inserted between these sleeves and the cam 21 so that when the shaft 22 is shifted axially in its bearings 23 the cam 21 is shifted in this direction, as is also the slide 18 with its needles 19. In other words, the shaft 22 serves not only for. actuating the cam 21., but also for actuating the slide 18. The axial movement of the shaft 22 is limited by spacing tubes 28 located upon said shaft between the sleeves: 26 and the walls 23 which latter serve, therefore, also as abutments for said spacing tubes (28).

The vertically movable vented from leaving the bottom slot of the gutter 11 by projections 29 provided at its ends, and preventing the ledge also from being drawn out unintentionally.

When the tongs is to be used. for undulating hair, this latter is placed in the usual ledge 20 is pre- I i turned too far, it is provided with projec tion contacting with the ledge when this latter has arrived in its lowermost position (Fig. 5). Thehair is therefore held fast between the middle portion of the gutter 12 and ledge 20. Now the slide 18 shifted in the one or the other direction according to its position upon the gutter ll, whereby the 7 free hair portions projecting forth between the rims of the utters arc shifted by the needles '19 "nto the proper position for the undulation procedure. Then the grip 25 is turned back into its former position Whereby the ledge 20, is permitted to re-enter the gutter 11,'end the adjusted hair held fast between the gutters until the heating procedure now following has been finished. 25

I Wishit to be understood that I do not limit myself'to the exactdrteils of tongs shown merel by we of examples. Various departures 'rom these details are possible Without, departing from the gist and scope of the invention.

I claim 1'. Hair undulating tongs, comprising, in combination with the grips and the of the tong body members, a gutterdike undulating member attached to one of said body members; another gutter-like undulating member attached to the other body member and adapted to be placed into the first-mentioned undulating member and having a longitudinal slot in its bottom; a ledge located in said slot and restingnpon the bottom of the first-mentioned undulating member;

m In

combination with the grips and the legs of the tong'body members, a gutter-like undulatin member attached to one of said body mem ers; another gutter-like undulating member attached to the other body member and adapted to be placed into the first-mom tioned undulating member and having a. longitudinal slot in its bottom; a ledge located in said slot and resting upon the bottom of the first-mentioned undulating member;

transverse ells in the second undulating member; a shaft extending through this member and located in said walls; a cam affixedto said shaft and bearing on saidledge; means for turning said shaft withsiud cam;

a slide located over said-second undulating gutter; and spikes extending'from the edges l p v of said slide towards the other undulating gutter, the 'saidsl aft with said slide and its spikes being longitudinally shiftable with respect to the saidtwo gutterdikeundulat lug-members, substantially and for the purpose set forth. 1
