HAIR CLIPPERS Filed Feb. 21, 1940 I E E Hara'n? Jo" g! Q Patented May 13, 1941 UNlTED STATES PAT NT OFFICE 3 Claims.

My invention is an improvement in hair clippers of that type which are especially adapted for cutting hairs from the recesses of the nostrils and ears.

It i a common practice to pull hairs from the nose and ears notwithstanding an infection may result from the breaking of the tender skin or membrane, and the use of an ordinary pair of scissors to cut the hairs is liable to have the same result for the reason that the pointed ends of the scissors are apt to puncture or nick the tender skin or membrane at the inner walls of the nose and ear. This has prompted the use of clippers of that type in which the cutting blades are in the form of slightly spaced teeth slidable upon each other for cutting and adapted to register to receive the hair between them, and it is to this general type of clippers that my invention relates.

The main object of my invention, therefore, is to provide a pair of clippers of the type mentioned which will cut hairs from the recesses of the nostrils and ears in such a manner that the tender skin or membrane will be thoroughly protected from injury while at the same time producing an effective hair cutting operation.

Having this principal object in view my invention consists in the production of a special form of clippers having the general appearance of manicure scissors and in which the ends of the cutting teeth are shaped to protect the skin or membrane with which they come in contact during the operation of cutting, as hereinafter fully described and more specifically set forth in the appended claims.

In the drawing forming a part of this specification:

Figure l is a plan view of a pair of clippers constructed in accordance with my invention.

Fig. 2 is a side elevation, the forward end portions of the blades being partly broken away to show the cutting teeth.

Figs. 3 and 4 are plan and side views of one of the cutting blades and its integrally connected operating handle.

Figs. 5 and 6 are similar views of the other cutting blade and handle, and

Fig. '7 is an enlarged transverse sectional view on the line 'I-'l of Fig. 2.

The clippers constructed in accordance with my invention are in the general form of manicure scissors of that type having gradually curved outer ends, and comprises crossed blades I0, I I pivoted together by a screw l 2 and having handles I3, l4 extending rearwardly therefrom and terminating in loops for the manipulation of the blades, but instead of the ordinary pair of blades with opposed longitudinal cutting edges the ends 1 of the blades in this instance are in the form of teeth with the teeth l5 of one of the blades slidable upon the teeth l6 of the other to cooperate in the cutting operation, and to effect a sharp cut one of the longitudinal edges of each tooth, with respect to both sets, is beveled as illustrated in Fig. '7 of the drawing.

In order to prevent the laterally movable cutting blades from injuring the skin or membrane when the hairs are being cut, as would occur should the toothed portion of one of the blades move beyond either side of the toothed portion of the companion blade, the lower blade, II, is provided with guards H, H at the side edges thereof, and the toothed portion of the upper blade is narrower than the toothed portion of said lower .blade so as to operate between the guards. Consequently there are more teeth on the lower blade than the upper blade, and for the purpose of protecting the skin or membrane from becoming punctured or nicked by the outer ends of the cutting teeth the outer ends of the teeth of the lower blade II are turned over the ends of the teeth of the upper blade, as indicated by the numeral I8, it being noted that the outer ends of the guards I1, I! are correspondingly curved. By this construction that end of the clippers which is inserted in a recess of the nostrils or ears, in cutting hairs therefrom, is blunt by reason of the curved ends of the teeth of the lower blade cooperating with the guards at opposite sides, and the hairs passing between the teeth will be cut when the blades are operated by the handles to slide one set of teeth over the other set.

It will be understood that the portions of the blades forming the teeth are very thin-with particular reference to the outer blade-so that the hair will be cut close to the skin, and by beveling the teeth as shown in Fig. '7 keener cutting edges are provided which will out without disturbing the roots, an important desideratum in clipping hairs from the tender skin or membrane at the inner walls of the nostrils. The beveling of the teeth of the outer blade to the outer face of the clippers provides inwardly tapered openings between the teeth into and through which the hairs will readily pass for the clipping operation.

As hereinbefore stated the blades are connected by a screw in the manner common to instruments of this kind, whereby the blades may be tightened one upon the other when desired, or when they become worn to a more or less extent.

As will be readily apparent my invention provides a handy implement which can be easily manipulated for cutting hairs from the recesses of the nostrils and ears without danger of injury to the skin.

I claim:

1. Clippers for cutting hair from the recesses of the nostrils and ears, comprising crossed blades pivoted together and having rearwardly projecting handles, the forward end portions of said blades being in the form of spaced apart teeth curved upwardly from the body of the blades with those of one of the blades slidable over those of the other blade, and the outer ends of the teeth of the lower blade bent over the outer ends of the upper blade for protection in the use of the clippers.

2. Clippers for cutting hair from the recesses of the nostrils and ears, comprising crossed blades pivoted together and having rearwardly projecting handles, the forward end portions of said blades being in the form of spaced apart teeth with the set of teeth of one of the blades narrower than the set of teeth of the other blade for transverse movement of the former within the scope of the latter, and guards at the sides 01' the wider blade for limiting the movement of the narrower blade and for protection in the use of the clippers, the toothed blades and the guards being curved upwardly from the body of the blades.

3. Clippers for cutting hair from the recesses of the nostrils and ears, comprising crossed blades pivoted together and having rearwardly projecting handles, the forward end portions of said blades being in the form of spaced apart teeth with the set of teeth of one of the blades narrower than the set of teeth of the other blade for transverse movement of the former within the scope of the latter, and guards at the sides of the wider blade for limiting the movement of the narrower blade and for protection in the use of the clippers, the toothed blades and the guards being curved upwardly, and the ends of the teeth of the lower blade turned over the ends of the teeth of the upper blade to cooperate with the guards for protection in the use of the clippers ERNEST E.
