(Cl. 132-11) The invention relates to an improvement in combs, and more particularly in hair dressing combs. Hair dressing combs, as heretofore constructed, 5 have comprised a longitudinally-extending back provided with teeth projecting outwardly from one edge of the back. The teeth may be ,all of the same. or of various sizes. The larger teeth are designated “coarse” teeth and the smaller teeth are designated “?ne” teeth. The spaces be tween the teeth are usually substantially of the teeth. teeth. hereinafter and particularly pointed out in the appended claims. These combs have usually been put out ' posed partly of coarse teeth and partly of ?ne teeth, the group or bank of coarse teeth being usually of substantially the same length as the 20 group of ?ne teeth. It is commonly known that the combs composed entirely of coarse teeth last or wear much longer than the combs that are composed entirely of ?ne teeth, and that in the case of the combs composed of both coarse and 2 a ?ne teeth the coarse teeth are not so easily broken as the ?ne teeth. In spite of the frequent break age of the ?ne teeth the demand for combs pro vided with such teeth is heavy and they are sup plied to the trade, but at the same time there has 30 been a growing protest against the easy breakage of the ?ne-teeth combs. Such combs are usually composed of hard rubber, although it has been proposed to produce combs composed of metal 45 55 60 prising a group of coarse and a group of ?ne same width as the thickness or width of the on the market in three forms:-.—(‘1) those com posed ‘entirely of coarse teeth; (2) those com posed entirely of ?ne teeth; and (3) those com 40 case of combs as heretofore constructed since they are protected by the relatively coarser teeth; the desired results in hair dressing may be obtained by the use of a single comb and Without the necessity of reversing the comb in the hand of the user; and also by gradually varying the width of the teeth and the spaces between them throughout the length of any one group of teeth, there is avoided the sharp line of demarcation which is so noticeable in combs of former construction com 110 and ‘also of the derivatives of cellulose materials. Although metal combs and combs composed of cellulosic materials are in considerable demand, hard rubber combs are the chief requirement of the trade. Whether a comb provided with only coarse teeth or with only ?ne teeth, or with both coarse and ?ne teeth shall be used depends upon the results desired in the dressing of the hair and partly upon the quantity and ‘relative coarseness or ?neness of the hair. According to the results desired a coarse toothed comb may be used ?rst and there after a ?ne toothed comb, or the coarse toothed end of a comb having both coarse and ?ne teeth may be used ?rst and then ‘the comb reversed in the hand of the user and the ?ne teeth used. In the comb of the present invention there may be a single bank or group of teeth or 'a plurality of groups of teeth. In each group, whether the comb comprises only a single bank or group of teeth or a plurality of groups, the teeth all vary gradually or progressively in width, and also the spaces between the teeth, from one end of the group to the other. By thus arranging the teeth of the group or groups, I obtain several novel results in the use of hair .dressing combs:-—-The ?ne teeth are not so likely to break as in the The invention is more fully described In the accompanying drawing illustrating the I preferred form of the invention, Fig. 1 is a side elevation of one form of comb embodying the in vention, Fig. 2 is a top plan of the comb shown in Fig. 1, and Figs. 3, 4 and 5 are diagrammatic side elevations of modi?cations of the improved 20 comb. The teeth of the comb produced according to the principle of the present invention may vary in width or thickness and the spaces between the teeth may vary in width, gradually or pro "25 gressively from one end of the comb to the other, such comb being shown in Fig. 1; or according to the results desired in the dressing of the hair, the teeth and the spaces between them may vary progressively in each group of a plurality of groups comprising the teeth of the comb. For example, the teeth at both ends of the comb may be relatively ?ne and gradually increase in width to the middle of the comb, or the teeth at both ends of the comb may be relatively coarse and decrease in width to the middle of the comb, or again a comb may have groups of teeth at more than two points thereon, the teeth of each group and the spaces between them being of gradually or progressively different widths. 4.0 In the form of the invention shown in Fig. 1, the comb illustrated comprises a longitudinally extending back or quill 1 having a group of spaced teeth extending outwardly from one edge and at each terminal a transversely-arranged heavy or relatively coarse guard tooth 8. The hair dressing teeth 9 of this comb gradually or progressively decrease in width from the relatively coarse teeth designated at I0 at the left hand end of the comb to the relatively ?ne teeth designated at H at the right handend of the comb, and the spaces be tween the teeth also vary in width, that is to say, each succeeding tooth from the left hand end of the comb decreases in width to the right hand end of the comb and the spaces between the teeth decrease in width from the left hand end of the comb to the right hand end of the comb. By means of this arrangement of the teeth of the comb several novel results are attained. In the ?rst place a single comb can be used to produce 60 2 2,126,214 as with the present forms of comb having both coarse and ?ne teeth the same results, but in an improved and more advantageous manner, since there are gradations in the widths of the teeth intermediate the coarsest and the ?nest teeth. In the next place the ?ner teeth are to a large extent protected against breakage by gradually increasing their width from the ?nest tooth adja cent the right hand guard tooth, and in the third 10 place, the comb presents a more pleasing ap pearance, since the teeth gradually vary in width and in spacing from one end of the comb to the other without the sharp break or line of demarca tion which is so obvious in the present style of 15 comb in which one-half of the comb is composed entirely of the coarser teeth and the other half of the comb is composed entirely of the ?ner teeth, all of the coarser teeth being of substan tially the same width and spacing and all of the 20 ?ner teeth being substantially the same width and spacing. ' In the form of the invention shown in Fig. 3,. the relatively coarse teeth l3 are placed at each end of the comb‘ and they as well as the spaces 25 between them gradually or progressively decrease in width to the middle of the comb, indicated by the relatively ?ne teeth M. In this form of comb it is not necessary to reverse the position of the comb in the hand of the user in order ‘to secure 30 the results in hair dressing to be obtained from the alternate use of relatively coarse and rela dressing may be attained by varying the arrange ment of the differently sized teeth according to the effects desired. And moreover, by gradually varying the widths of the teeth and the spaces between them a long bank of relatively ?ne teeth is avoided and therefore the liability of breakage is correspondingly obviated. This results in giv ing combs having ?ne teeth a much longer period of use than it has been possible with such combs as heretofore constructed, especially those com 10 posed of hard rubber or similar material which when in a state of ?ne subdivision may be easily broken. It will be further understood that according to the principle of the invention it is not necessary that each tooth be either larger or smaller than the next preceding or succeeding tooth, the es sence of the invention being that in any group of teeth there is in either longitudinal direction a gradual or progressive increase or decrease of width of teeth and the spaces between them. For example, two or three, or even more, teeth of a group or bank may be of substantially the same size followed by a similar group of larger or smaller size, the group of teeth as a whole 25 varying gradually or progressively in size from one end to the other. Having thus described the invention, what I claim as new is: 1. Ina hair dressing comb comprising an elon 30 gated back, a group of teeth extending outwardly tively ?nelteeth, or the results which may be‘ from one edge of said back, said teeth being all obtained by the use of teeth intermediate in size of different widths from one end of the group to between the coarsest teeth and the ?nest teeth. the other. 35 These same results can be obtained by use of the 2. In a hair dressing comb comprising an elon comb shown in Fig. 4 in which the ?nest teeth gated back, a group of spaced teeth extending l5 are located at the two ends of the comb and outwardly from one edge of said back, said teeth the coarsest teeth l6 are located at the middle and the spaces between them being of progres of the comb, the teeth at both ends of the comb sively different widths from one end of the group 40 and the spacing between them gradually increas to the other. 4,0 ing in width from the ends of the comb of the 3.

A hair dressing comb comprising an elon indicated at l9. In this form of the invention especially, the ?ner teeth are protected against breakage by the adjacent groups of relatively coarse teeth. From the foregoing description taken in con nection with the accompanying drawing, it will be apparent that novel results have been pro duced in hair dressing combs. The ?rst is the fact that a comb provided with both coarse and ?ne teeth has been produced in which there is no sharp division between the coarse and ?ne teeth, but a gradual change in the size of the teeth imperceptible to the eye which greatly en hances the appearance of a comb in which both 70 coarse and ?ne teeth are desired. It will also be apparent that numerous novel effects in hair gated back having at each end an outwardly ex tending relatively coarse guard tooth, and a plurality of groups of spaced teeth extending outwardly from one edge of the back and located between the guard teeth, the teeth of each group 60 and the spaces between them being of progres sively different widths from one end of the group to the other. 6.
