A. J. DREMEL HAIR CLIPPER Filed April 30, 1932 WLJJJ Patented Dec. 1 1933 UNITED STATES PATENT OFFICE 3 Claims.

This invention pertains to hair clippers, and more particularly to the cutting blades.

In cutting hair, and more particularly womens hair, it is often desirous to merely thin out the hair rather than remove a single bunch of hair from one area. Heretofore it has been a tedious and difficult operation, requiring unusual skill, due to the fact that uniformly spaced cuts must be made some distance from the scalp rather than to cutout a single portion close to the scalp, which would soon result in short, stiff hairs projecting through the longer, overlapping hairs.

The present invention has primarily for its object to provide a pair of clipper blades having cooperating teeth so spaced as to enable the operator to readily cut out uniform spaced portions of hair without exercising any appreciable skill.

Incidental to the foregoing, a more specific object resides in the provision of cooperating stationary and movable cutter blades having their teeth so spaced and relatively movable that upon insertion of the teeth transversely into the strands of hair, uniform spaced portions of hair are cut out.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

Figure 1 is a plan view of a pair of clipper blades constructed in accordance with the present invention.

Figure 2 is a plan view of the stationary blade.

Figures 3 and 4 are fragmentary plan views illustrating the movement of the movable blade relative to the stationary blade, and

Figure 5 is a side elevation of the blades.

Before describing the invention in detail, it is to be understood that the same is applicable to blades utilized in either manual, motor-driven or electrically actuated clippers, and while a relative arrangement has been illustrated, between the teeth of the stationary and movable blades, v the same can be readily reversed to produce the 55 same result.

The particular structure of blades illustrated is designed for use in connection with a conventional type of electric clipper, such as illustrated in Patent No. 1,701,148 and therefore it is considered unnecessary to go into a detailed description of'the method of guiding and actuating the movable blade on the stationary blade. Suffice it to say,-the movable blade is reciprocated transversely'on the stationary blade, the teeth of which cooperate with those of the movable blade to cut or sever the hairs projecting therebetween.

Referring now more particularly to the accompanying drawing, the numeral 1 designates a clipper blade provided with substantially spaced teeth 2. Reciprocatively mounted on the stationary blade is a movable blade 3 provided with correspondingly spaced pairs of teeth 4 normally alined with the teeth of the stationary blade, as disclosed in Figure 1.

In operation the actuating means (not shown) for transversely reciprocating the movable blade on the stationary blade is so designed as to limit the movement of the movable blade to substantially the distance between the ends of the pairs of teeth carried by the movable blade, as illustrated in Figures 3 and 4. In utilizing the blades constructed in accordance with the present invention, the teeth are inserted transversely into the strands of hair, as indicated in Figures 1 and 5, the dotted showing in Figure 1 indicating the strands of hair in cross section, while the strands shown in connection with Figure 5 represent the hair in elevation.

From the foregoing explanation taken in connection with the accompanying drawing, it is deemed that the action of the blades will be quiteapparent in that the spaced teeth of the stationary blade, cooperating with the correspondingly spaced pairs of teeth provided on the movable blade, will efiect cutting of uniform spaced portions of hair, leaving the intermediate strands uncut, thus effectively and unnoticeably thinning out the hair, as indicated in Figure 1.

While the teeth of the movable blade are shown, in spaced pairs, it will be readily appreciated that a conventional blade with uniformly spaced teeth may also be employed, in which instance those teeth traveling intermediately of 105 the spaced stationary teeth will be ineffectual and the same results will be obtainable. Also, as previously suggested, the arrangement of teeth heretofore described may be reversed to provide the same results.

being limited to effect cutting of only spaced portions of hair.

3, In a hair clipper, a stationary blade provided with cutting teeth, and a movable blade having cooperating cutting teeth projecting in the same direction, the teeth of one blade being substantially spaced apart, and those of the other blade being arranged in correspondingly spaced pairs, each of said pairs cooperating only with the alined tooth of the adjacent blade to effect the cutting of only spaced portions of hair.
