Se t. 4, 1956 F. KAUL APPARATUS FOR HAIR-DYEING Filed Oct. 5, 1953 INVENTOR. FRED KA UL United States Patent APPARATUS FOR HAIR-DYEING Fred Kan], Buenos Aires, Argentina Application October 5, 1953, Serial No. 384,179
6 Claims. (Cl. 132-109) The present invention relates to improvements in apparatus for hair dyeing wherein the dyestuif is applied to the hair without staining the scalp or other parts of the skin.
More particularly it concerns a novel apparatus for hair dyeing in which the dyestuff container is enclosed within a removable toothed cover plate. I
In the applicants U. S. Patent No. 2,660,182, dated November 24, 1953, there is disclosed an apparatus for hair dyeing which comprises a plate having teeth along two opposite sides and a handle, a second handle of substantially equal length to the combined length of said plate and said first handle, said handles being joined by an axle at the ends thereof on which they turn, one or two movable rolls rotatably mounted on said second handle at the end remote from said axle, said rolls being formed of an absorbent material suitable for holding a dyestuif, and a slide ring adapted to embrace said handles whereby by making said slide swing upwards the apparatus is closed, and by making said slide swing downwards to said axle the apparatus is opened.
This apparatus advanced considerably the hair dyeing process, since it eliminated the necessity of applying the dyestutf to the hair by means like a brush or a piece of cotton, which render the dyeing of the hair more difiicult and often stain the scalp and other parts of the skin.
While the apparatus described in the above mentioned U. S. Patent No. 2,660,182, usually produced good results, it was found a little complicated and of an expensive manufacture. Furthermore, when passing the apparatus through the hair, a certain care was required in such a way that the toothed plate would rest on the skin, whilst the rolls remained on the outside of the plate. If the rolls were passed directly on the hair without the interposition of the plate, a staining of the scalp or other parts of the skin could occur.
It is an object of the present invention, accordingly, to provide a new and improved apparatus for hair-dyeing, by means of which the hair-dyeing may be obtained without exercising excessive care to prevent the staining of the scalp or other parts of the skin.
It is another object of the present invention, to provide an apparatus for hair-dyeing which comprises a plate with a dyestuff-container along one edge, and a toothed cover adapted to receive the strands of hair to be dyed.
Another object of the invention is, to provide a new and improved apparatus of the above character which affords a most simple and effective means for hair-dyeing, of simple construction, which can be easily manufactured on an extensive scale at a low cost, compact, and easy to operate.
The invention may be better understood from the following detailed description of a representative embodiment illustrated in the accompanying drawings in which:
Fig. 1 is a perspective view of an apparatus according to the invention showing the same with the cover in lifted position;
Fig. 2 is a horizontal sectional view taken along line 1-1 of Fig. 1;
Fig. 3 is a side elevation view of the apparatus showing same in operative position; and
Fig. 4 is a vertical sectional view along lines 11-11 of Fig. 3 and showing the apparatus being applied to the hair.
Referring now to these drawings, the apparatus for hair dyeing comprises a plate 1, of plastic material or any other suitable material, having a dyestutf container or dyestuff holding means, such as a brush or a felt-padding or any other absorbent material 2, along one longitudinal edge 3. The said plate is further provided with a hole 4 in the middle. The handle 5 is formed by the end of the plate 1.
The said plate has a cover 6 consisting of a folded plate having a number of teeth 7 along both the longitudinal edges, the said cover having a hole 8 on each of the substantially lateral planes in alignment with the hole 4 of the handle, the cover being hinged to the plate by means of a rivet 9 or the like, passed through said mentioned holes.
The toothed portion of the cover is slightly broader in width and surpasses slightly the dyestuff container or brush 2. The said container extending from the plate does not reach the ends of the teeth of the cover 6, when the apparatus is used, as shown in Fig. 3. The dyestuff container 2 thus is situated between the two rows of teeth 7.
The cover 6 is also provided at one end With a lever 1f fixed to the holes 8, which serves for lifting the cover 6 by pressing on said lever. For retaining the cover in closed position embracing the plate and dyestuff container, the cover is further provided with inward projections 12 that clip on the plate to prevent the opening of the cover when the apparatus is passed through the hair at a normal pressure, but that allow the manually opening or lifting of same for impregnating the dyestuff container.
For using the apparatus, first a finger pressure is exercised on the lever of bridge 11 by which the cover 6 is lifted in upward position, as shown in Fig. 1. Then the dyestuff container or brush 2 is impregnated, and after this, the apparatus is closed by pressing down the hinged cover 6 until the inward projections 12 clip on the inferior portion of the plate 1. Now the apparatus is ready for use in the following manner:
Taking hold of the handle, the apparatus is passed through the hair in such a way that the end of the teeth rest on the scalp or skin. The dyestuif container or brush is thus separated a certain distance from the scalp, as shown in Fig. 4. By moving the apparatus in the direction of the hair or opposite, the hair will find its way between the teeth getting in contact with the dyestulf.
Accordingly, the present invention provides a novel and improved apparatus for hair-dyeing, in which the dyestuff is isolated from the scalp or other parts of the skin, at the same time bein readily disposed for moistening and dyeing the hair.
While various changes may be made in the detailed construction, it shall be understood that such changes shall be Wi hin the spirit and scope of the prevent invention as defined by the appendant claims.
Having thus set forth and disclosed the nature of the invention, what is claimed is:
l. An apparatus for hair dyeing comprising a plate with a handle, a dyestuff container mounted along one longitudinal edge of said plate, a cover consisting of a folded plate having a number of teeth along both the longitudinal edges thereof and being mounted on said plate so as to embrace said plate in such a way that the dyestuff container is situated between said two rows of teeth.
2. An apparatus for hair-dyeing comprising a plate with an elongated handle, a dyestufi brush mounted along the edges and being mounted on said plate so as to allow said brush to be impregnated.
