In Germany June 18, 1931 4 Claims. (01. so-n' This invention relates to. a hair thinning out plate 2. During practical application of the dedevice adapted to be'used for ravelling out work. vice to thick hair the formeris passed through Compared with existing devices for ravelling the latter from below and the plate I held so that or thinning out hair, which comprise scisors havthe top layer will be adjacent to the bushing 5 5 ing notches in their cutting surfaces, the thinning and thus cannot be 'ravelled out, owing to the ar- 5 out device according to the-invention permits merangement of a recess 6' on each tooth. When the chanical and uniform ravelling out during combhair is of medium thickness or quite thin, the ing and can be used satisfactorily even by inoperator will hold the comb obliquely to placethe; experienced persons who have not been trained top layer of the hair in the zone where it cannot 10 in the difiicult technic of ravelling out which be cut. This latter manipulation is quite in keep- 10 differs from that of hair cutting in so far as the ing with the customary practice of hair-dressers hair has to be uniformly thinned in spots and who always hold the comb in a slanting positionnot to be uniformly shortened by cutting. when handling thin hair which they press against By way of example, the invention is illustrated the back of the comb to form it into a unit. When in the accompanying drawings, in which Figure applying the device according to the invention, 15
1 is a vertical section of two superposed cutting hair-dressers need therefore not to change their plates having a comb like form and being partly usual methods of handling combs and will still provided with recesses; Fig. 2, a similar section be absolutely sure of retaining'the long covering as Fig. 1 of a known device without recesses; Fig. top hairs. 3, an elevation, partly in section, of the-ravelllng As Fig. 3 indicates, the plates I, 2 are moved 20 out device ready for work; Fig. 4, an enlarged relatively to one another only to such an extent longitudinal section of two superposed teeth of that their teeth approximately cover each other the comb-like plates with recesses; Figs. 5 to '7 whenin a position of rest. Inoperative position, are cross sections of the teeth of the superposed on'the other hand, the teeth of one plate would cutting platesshowing difierentforms of recesses. cover the openings 4- of the other. Compared 25 Referring to the drawings, the thinning out with existing devices, the device according to the device according to the invention has teeth which invention has little stroke and need not to be discomprise a stationary cutting plate I and a cutplaced to the extent of three, four or more teeth 1 ting plate 2, moving over plate I, both plateshavat each cutting operation. In order to attain this ing a comb-like form and the-cutting of the hair the openings 4- are smaller than the adjacent 30 a for thinning being effected between the teeth of t'eeth, which makes it possibletodispose, for inthe p T cutting d s '.0f the teeth are stance, a tooth of the movable plate 2 in a fully Provided w th the recesses 6 an d 'I', so that only covered position behind a member of the stationthe cutting portio s 9 remain on P ate ary plate I, and have the opening 4 subsequently The recesses 1 Will m dat h e heirs fully covered by the larger tooth of the movable that are not to'be ravelled out while the device plate 2. This covering is so, amply dimensioned ispessing through them, a d these recesses a W l that it amounts at the overlapping edge portions as e p rt ons 9 of the cutting P ate 2 are of to at least one-tenth of a millimeter, so that difierent size in consecutive teeth to render ravelthe edge portions may serve as cutting edges sons can therefore 'ravel out hair with a device ling Out as vi ible es Dessible; By. stagger n for cutting off the hairs to be ravelled out. 40
the cu ting ed e po 9 u orm cu n a In Fig. 3, the movable plate 2 is provided'with act on s a d d a even pe i d pe only halfas many teeth as the stationary plate I,
so that every other opening 3 will remain opened also during operation. .The, openings 3 may be arranged in any desired number. The openings 4 are shown to be approximately of equal width according to the invention in a satisfactory manner. I e i As shown in Fig. 1, the cutting members of the 3 2 gfigg f i ggg g s; $3: gagg g: up to the top and have parallel edges, as ithas which automatically prevents the top layer been found that this construction is the most pracof the hair, the most important element in hairheal and P other shapes may 50 dressing, from being subjected to ravemng out 'course, provided they can be closed by a cover ng operations. The recess 5 could be arranged also tooth of themovable plate 2, in working position. in the stationary cutting plate I; or in both plates At the mints Where teeth of one Plate l and 2, though numerou te t ha shown th t .the openings of the other a closed front will be it sufllces to provide for a recess 6 in the movable p du which pp y w ll Pr v nt the hairs 55 from passing during further motion of the device. However, numerous experiments have shown that, owing to the complete closing of the openings 4, the hairs cannot move behind the teeth during the return of the movable plate 2, so that this apparent drawback insures increased safety in operation and perfect freedom from pulling.
Furthermore, according to Figs. 4 to 7, the teeth of the movable plate 2 may be provided with the recesses I0 disposed approximately vertically to the direction of motion, as clearly indicated in Fig. 5, since experiments have proved that a smooth release of the hair from the closing teeth of the movable plate 2 and stationary plate I will be insured when the recesses ID are thus disposed. When the device according to the invention is moved through the hair, the recesses Ill.
if vertically arranged to the direction of motion of the cutting plates will be in a more favorable position relative to the direction of motion of the hair, which will be approximately similar to the one in which the latter will be drawn out of the teeth.
As stated before, the teeth of the plates I, 2 having the cutting faces 8, 9 are provided with the recesses I to protect the hairs pressed into the recesses during operation of the device from being cut off. In order to facilitate withdrawal of these pressed in hairs, the entrance edges of the recesses I0 in Fig. 6 are rounded. Fig. 6 further shows how the recesses I2 vertically disposed to the direction of motion of the plates I, 2 may be positioned in the stationary plate I, the recesses shown being only partial unlike the complete recesses I0 in Fig. 5. If the recesses I2 are provided in the stationary plate I, the recesses I0 in the movable plate 2 may be made smaller to reduce the tooth only slightly in size.
The vertical recesses in the plate 2 may be curved at Ila and MD, or these curves may be provided on the stationary plate I, or on both parts I and 2.
Fig. '7 shows how in addition to the vertical recesses II], I2 the recesses 6, I, which extend parallel to the direction of motion of the device, may be provided. The combination of these recesses facilitates the withdrawal of the hairs which are not to be ravelled out from the closed teeth. Even long covering hairs need no longer to be combed to the side as is now required but may remain where they are during the ravelling out process, and the hair-dresser can observe the effect of his work directly.
Fig. 4 shows how the recesses 6, I and I0, I2 vertically disposed relative to one another are positioned in the plates I, 2 so as to always form the same channels. Furthermore, the vertical channels ID in the movable plate 2 are bent towards the teeth to provide a more favorable angle for the outlet of the hairs extending obliquely to the scalp and to prevent them from being injured by the edges of the recesses I0, I2. The shape of the bend is immaterial and may be straight or curved. The bend need further to be provided only at the lower edge while the upper edge may continue to extend vertically. The vertical recesses I0 may be more or less slanting, according to the invention. Fig. 4 further illustrates how by a suitable arrangement of the recesses absolute protection of the hairs of the top layer will be positively assured, as in Fig. 1, since all teeth which count in operation are provided with particularly large recesses 6, I0 near the point where they extend into the plates I, 2, so that the device can be used also for long and heavy covering hair without exposing it to ravelling out.
