-' In the processof cutting a trimming the hair,
the hairdresser must repeatedly 'go over the hair, ,in using the ordinary type of hairdressers or barbers comb, in order .that when the hair cut ting operation islcompleted, the. hair will not .'show:1ines' o'r ridges orhave a'stepped appear- .ance. hair several times .in order to' avoidthe formation of a." ridged or stepped appearance, consid- Due tozthis necessity for going Over the erable time is consumedwhich can be avoided by the use of a comb which has kerfs of'varying depths between its teeth. Such combs as hitherto used for this purpose have too drastic a change from shallow kerfs to deep kerfs which prevents the hair from getting into the deep kerfs. Particularly if the hair is heavy, not enough hair is between the teeth or the hair is blocked up. The same disadvantages occur if the bottoms of the kerfs are arranged in such a manner that they form a base line of wavy or zigzag contour.
It is, therefore, the main object of the present invention to provide a comb of the character described which will slide through the hair more easily and smoothly and with less resistance than similar combs hitherto used, thus eliminating any pulling of the hair, and which allows a more efficient use 01' clippers so that any clogging or overfeeding of the clipper will be avoided when cutting over the comb;
Another object of the present invention is the provision of a comb of the character described which is not only more eflicient in use but also more sanitary and which will not pick up and accumulate between the teeth the dust, or other deposits or impurities which may be in the hair; A further object of the present invention is the provision of a comb or the character described which will not tilt the clippers or shears into the teeth of the comb and which will allow the hair to fit and blend in an exacting manner after it has been cut.
Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawing whether within or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained similar parts "tween theterminal or end teeth, are divided preferably in a row of 'coarse teeth 3 and a row of fine teeth 4. The slots or kerfs between theteeth are of different depths, and the teeth ,and kerfs are arranged in groups, preferably in groups of four as in the instance shown. The shallowest kerr 5 in each group is next to the deepest kerf 6, and the third kerf 1 is slightly deeper than the shallowest kerf 5, whereas the fourth kerf 8 is slightly shallower than the deepest kerf 6 but deeper than the third kerf 1. I prefer to make the deepest kerf 6 in each group of the coarse teeth 3 about of an inch deeper than the shallowest kerf 5, and the third kerf I about onesixteenth of an inch deeper than kerf 5, and the fourth kerf 8 about one-eighth of an inch deeper than kerf 5. I also prefer to make the kerfs between the fine teeth 4 relatively slightly shallower than the depths of the kerfs between the coarse teeth. The diiferences in the depths of the kerfs between the fine teeth are accordingly slightly smaller than those in the depths of the kerfs between the coarse teeth.
The comb tapers from a 'wide end to a narrow end so that the points of the teeth are on a line which converges toward the back edge of the comb. Accordingly, the depths of the various groups of kerfs between the teeth decreases throughout the comb from the wide end towards the narrow end, as may be seen in the drawing, but the depth-differences within each group remain substantially the same as previously referred to.
The slots or kerfs are substantially U-shaped and are rounded over smoothly between the teeth so that all sharp edges are eliminated. This will prevent the adhesion and accumulation of dust and other impurities which may be in the hair and it will allow the comb to slide smoothly and easily through the hair with the slightest possible resistance, thus eliminating any pulling of the hair. The back I of the comb is primarily flat and rectangular in cross-section, and the teeth have a slight slope inwardly from the center of the teeth to the back of the comb. This will prevent the clippers and shears (not shown) from dipping and jabbing into the teeth of the comb so that miscuts will be avoided. It also slopes slightly forward to the front edge of the teeth. Thus the hair will be picked up better.
The arrangement of the kerfs 5, 6, I and 8 previouly referred to lets the hair spread out so they will .not beso thick in one straight line, allowing it to feed "inbetween clipper teeth, so the clipper can handle it, and cut the hair oil without clogging. This also will allow the hair; to fit and blend in an exacting manner, after it Y i 15 i of coarse teeth which is followed by a row of fine has been cut.
This comb can be made out of hard .rubber,
or beryllium copper or any suitable material; My comb will be well balanced. It will hold'andtake" a sufficient amount of hair because teeth being.
of ample length, there will be no crowdinghair away, because of short depths.
While there has been, shown and described and'pointe'd out the fundamental n'ovelieatures of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and initszoperation may be made by those skilled in the art without departing from the spirit of the invention'. It is the intention, therefore, to' be limited only as indicated by the scope of the following claims. 1 a 7 Having thus described my invention, what I claim and desire to secure by-Let'ters Patent in the United States is: r
1. A barbers comb including a back and teeth, there being kerfs of difl'erent depths between the teeth, said teeth and kerfs bein arranged in groups of four throughout the comb, the shallowest kerf in each group bein next the deepest kerf and the next following third kerf being slightly deeper than the shallowest and the fourth kerf being slightly shallower than the third kerf, the bottoms of all kerfs being rounded so as to eliminate all sharp edges, and the back of the comb being substantially rectangular in cross-section, and the teeth having I a slight slope inwardly from their center to said back, all substantially as described.
2. A barbers comb including a back and a row teeth, there being kerfs of different depths between the teeth, said teeth and kerfs being arran ed in groups of four throughout the comb, the shallowest kerf in each group being next the 'deepest kerf and the next following third kerf being slightly deeper than the shallowest and the fourth kerf being slightly shallower thanthe deepest but deeper than the third kerf, all the kerfs between the coarse teeth being deeperithan the kerfs between the fine teeth and there being a largeri difference in the depths of the kerfstbetween the coarse teeth than there is between the fine teeth, the bottoms of all .k'er fs being rounded so as to eliminate all sharp edges;tand"ithe back of the comb being substantially rectangular in crosssection, and the teeth having a slight slope inwardly from their center to saidba'ck, all substantially as described.
