To all whom it may concern:

Be it known that I, SAMUEL T. CRAWFORD,

a citizen of the Unlted States residing at- Washington, inthe District of Columbia, have invented new and useful Improvements in Combs, of which the following is a spec1- fication.

This invention relates to combs and particularly that class adapted for use by barbers for cutting hair.

The primary object of the invention is to provide a comb of the class specified having a well balanced organization and a tooth structure and configuration to effectively catch the hair and gradually and evenly raise it from the scalp to a degree in ao-, cordance with the length of the cut desired.

to be made. A further object of the invention is to form-a barbers hair cutting comb with a plurality of teeth having opposed concavo-convex edges whereby the teeth as a unit during operation will have an easy and regular fulcruming movement on their convex edges and an upper concave recess formed by their concave edges for positlve cutting application of shears therein, A still further object of the invention 1s to provide a comb having a plurality of teeth with opposed concavo-convex edges forming as a unit, respectively, a convex fulcruming back and a concave cutting recess and being reversible to bring the free ends of the teeth in position for massagmg the scalp and loosening and removing dandruff.

With" these and other objects and advantages in view, the invention consists in the construction and arrangement of the several parts more fully hereinafter described .and claimed.

In the drawing Figure 1 is'a perspective view of a comb embodying the features of the invention.

Fig. 2 1s a, top plan view of the comb.

The numerals 5, 6 and 7, respectlvely, designate the comb back, teeth and handle which are all preferably of integral construction, and in practice the comb as an entirety will be formed of some sultable light material, such as alumlnum. Any ma 7 to its free end and has an outer substantially convex side 8 and an inner flat side 9, the teeth rojecting from the flat side. By tapering t e back 5 the thickness thereof is gradually reduced toward its free end to efiect a balancing action thereof when 0 rated b the barber who grasps the handle 7 ThlS andle 7 is also tapered toward its rear free end, the thickest part of the back and handle being at their point'of juncture ad acent to the innermost tooth 6. By this construction the back as a whole maybe utih zed as a :Iiulcruming means to impart a partlal rolling operation to the comb, or, by proper manipulation of the handle, the comb may be tilted longitudinally and the thickest part of the back at the-juncture thereof with the handle alone Serve as the fulcrum. These varying operations of the comb will be effected to accommodate the particular kind of cutto be made or found necessary in general hair shearing and trimming operations.

The teeth 6 are all the same Sue and have broad bases 10 from which they converge to the free pointed ends 11, the back edges 12 of the teeth being convex and facilitating the partial rolling operation of the comb, and the inner edges 13 being concave and pro viding an inner curved recess in which the shears are disposed to cut the hair brought up between the teeth and extending above the said concave edges 13. The shears may be placed at any point alon the concave edges 13 of the teeth in accordance with the len h of cut to be made. The length of cut of t e hair will also be controlled by the engagement or position of the back edges 12 of the teeth relative to the scalp, it being obviously apparent that when the pointed ends 11 of the teeth are close to the scalp that a shorter cut of the hair may be made than when the intermediate portions of the back edges 12 of the teeth engage the scalp and the pointed ends 11 are clear of the latter. The teeth may be effectively used as means for massaging the scalp and loosening dandruff by reversing or overturning the comb so that the back edges 12 of the teeth are uppermost and their concave edges 11 in lower positions, thereby providing a clearance at the bottom portions of the teeth in rear of their points or between the latter and the back 5 which will result in a more effective operation by clearin the hair that may be located between t e teeth points and the back. In this reverse position of the comb to efi'ect a ,mas-

sage treatment of the scalp and loosening of dandruff, the comb will be held down flat with all the teeth in engagement with the scalp and a portion of the back 5 of the comb will rest upon the hair. The treatment of the scalp and the hair by reversing the comb as just explained will also be effective 1n cleanmg out loose hair clippings from the cut ham and brin ing'the same to the surface, the loose or c ipped hair being forced upwardly from the convex edges ofthe teeth.

The improved comb is also very advantageous in hair culture operations or treatments of the'scalp without breaking the lat-' ter. It fructifies the scalpand encourages the growth of the hair, and the dandruff that is loosened is raised to the surface of the hair from which it may be easily removed by a brush. Subsequent to shampoo or, other moisture treatment of the hair the improved comb will be found effective in drying the hair. Moreover, it will be seen that the teeth of the comb are relatively close, or, separated by very narrow spaces, and as a consequence will serve more efliciently in hair cutting operations by bringing up and holding hair in closely confined looks or portions.

The teeth of the comb are formed in a strong and durable manner so that they cannot be readily broken or distorted, and in view of the greatest width of the teeth being located adjacent to the back or formed at the point of juncture of the teeth with the back, the said teeth may be constructed relatively thin and will be materially reinforced against fracture. It will also be understood that the teeth may be' arranged as close or as far apart as desired and asmay be found tained in hygenic condition, and it may be made in various sizes.

What is claimed is A comb of the class specified having a back extending from 'a handle, the back taporing from the handle portion to the front end of the comb and having. a rear convex side and a front longitudinally straight flat side, a plurality of teeth all of equal length projectln from the front flat side of the back and aving'lower convex sides merging regularly into the said convex rear side of the back to provide a smooth rolling surface formed by the combined lower'edges of the teeth and the rear side of the back, the teeth tapering toward their free ends and having upper uniform concave edges to provide a concave recess throughout the series of the teeth forapplication in said recess of cutting shears, the tapering back gradually reduced toward its free end effecting a balancing acby gripping the handle and whereby the comb may also be tilted longitudinally and the thickest part of the back at the juncture with the handle serving alone as the fulcrum for operating the comb to permit varying length cuts to be made with the comb.

In testimony whereof I have hereunto set my hand in presence of a subscribing witness.
