HAIR CLIPPING DEVICE Filed Aug. 22, 1968 INVENTOR CURTIS W. NEEL Y Fl 6. 3 BY W ATTORNEY 3,534,473 HAIR CLIPPING DEVICE Curtis W. Neely, RA 18091388, 95th Engr. Co. (BL), 29th Engr. Bu. (Bt), APO San Francisco, Calif. Filed Aug. 22, 1968, Ser. No. 754,561 Int. Cl. B2611 19/02 US. Cl. 30--29.5 7 Claims ABSTRACT OF THE DISCLOSURE The invention is for a hair clipper adapted to clip or cut hairs and the like within a persons nostrils. It is a tubular designed article having slidable cutter means at one end and a push-pull arrangement at the other end for operation of the cutter means. A spring means is employed for shifting the cutter means in one direction.

This invention relates to hair clippers and is especially designed and configurated to fit into the nostrils and the parts thereof are coordinated to do the cutting in a safe and harmless manner. The clipper is a simple device of few parts and can be manufactured economically and sold at a very reasonable price.

One of the important objects of this invention is to present a hair cutting device that is easy to slip into a persons nose and to painlessly cut the hairs in the nostrils and the operation is accomplished by a single hand, and the device is easy to keep in perfect condition for long and useful service.

Another object is to provide a nostril type of hair cutter wherein the cutter thereof does not come into contact with the skin portion of the nostrils, that is, the cutting edge is set back away from the skin of the nose.

Still another object is to provide a nose type of hair clipper that involves a pair of sliding tubular elements that are concentrically arranged and wherein one end of the combined parts has a push surface to be operated by an operators thumb against a grip means and a spring means provided to return the cutter means to its original position.

Other objects of this invention will become apparent from a careful inspection of the specifications and claims and the drawings which are made part and parcel hereof.

In the drawings:

FIG. 1 is a side elevational view of the hair clipper showing some parts thereof in section and a part broken away;

FIG. 2 is a top view of a portion of the invention and especially the top view of that shown in FIG. 1;

FIG. 3 is a top portional view showing the casing per se;

FIG. 4 is an end elevational view with a portion thereof in sectional view;

FIG. 5 is an enlarged elevational view taken along the line 55 of FIG. 1;

FIG. 6 is an elevational view similar to that shown in FIG. 1 but showing the clipper when the cutting means is at its extreme forward position; a part of the gripping means is broken away.

Reference is now made to the various parts of the drawing wherein one form of the invention is illustrated. The part 1 is an exterior tubular casing or cover having at one end thereof a bevelled portion 2. which presents a circular cutting edge or periphery 3. This cutting edge is made razor sharp and therefore should be of suitable metal and the edge conditioned for hair cutting. At the other end of the casing 1 there is a push surface 4 designed to accommodate an operators finger which would normally be the thumb. A pair of oppositely arranged slots 5 and 6 are provided in the casing, as indicated, and the nited States Patent slots serve a particular purpose which will later become apparent.

Within the tubular cover or casing 1 there is snugly inserted an inner liner element 7 which is tubular and concentric with the casing and which has the opposed stop elements 8 and 9; the stop 8 being positioned in the slot 5 and the stop 9 positioned in the slot 6 of the casing. These stops could be integral with the body of the liner 7 but for ease in assemblin the parts it is preferable that they be cemented or otherwise fixed to the liner, but note that the stops are in a raised position with respect to the surface of the casing so as to avoid friction of the operators fingers upon the grip means 13-14 and the outer surface of the casing. The rear end of the liner 7 is provided with a protruded portion 10 which is adapted to snugly enter a circular groove 12 of the grip means and is securely cemented thereto. The grip wings 1314 are designed to be gripped by an operators fingers and are only large enough for such a purpose.

In assembling the parts, the spring 15 would obviously be inserted into position first within the casing 1 and then the grip means 11 inserted. The liner 7 is then passed through the forward opening of the casing and its rear end snugly forced into the groove 12 of the grip means 11. After this, the stops 8 and 9 are positioned onto the liner. A suitable cement can be used to hold the mentioned parts together, but however, if preferred, small screws can be used to hold the parts in the proper positions.

The distal end or front end of the insert tube or liner 7 is provided with a plurality of extensions on prongs indicated at 16, 17, 18, 19, 20 and 21. These prongs are shaped and arranged as shown, and they are fixed to the internal tube or liner 7 in the event that the liner and prongs are made of different material, The liner 7 and its prongs and also the handle or grip means 11 may be of any suitable material such as metal or any of the well known plastics. Unless the cutting edge portion 2 of the casing is made of a separate part to be attached to the main body of the casing, the entire casing then must be made of a suitable stainless steel and the cutting edge 3 conditioned in a manner to be made razor sharp for cutting hair. The prongs are made of spring material and sprung outward slightly so that when the cutting edge 3 is pushed forward, the prongs are forced against each other to close the openings between them; this action causes the prongs to hold the hair until released.

The prongs are made smooth and free of sharp or ragged edges so as not to injure the skin of the nostrils. The prongs are shaped in a manner to provide tapered openings between them and thus provide a ready means to engage hair of the nose as the instrument or casing is inserted. The openings are so arranged to guide the hairs to the closed end and then hold them in proper position for the cutting edge 3 to cut them or clip them close to the skin but not close enough to cause any irratation of the skin. The operator merely inserts the instrument into the nostril and then give the push plate or surface 4 a positive forward thrust and the hairs are neatly clipped.

Certain novel features and details of this invention are disclosed herein, and in some cases in considerable detail, in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed, is not ncessarily limited to the exact form described and illustrated and to the details thereof since it is apparent that various modifications and changes may be made without departing from the spirit and scope of the invention as expressed in the appended claims.

Having thus described my invention, what is claimed as new and desired to be secured by Letters Patent is:

1. A hair clipper and the like having a casing with a reciprocable liner therein, a grip means exterior of the casing attached one end portion of the liner, a push surface on the casing adapted to cooperate with the grip means for relative shifting of the liner with respect to the casing, prongs extending exterior of the casing that are fixed to the liner and extending beyond the distal end of the casing, and the casing at its distal end having a cutter means for clipping hair tripped between the prongs.

2. The clipper recited in claim 1 wherein the prongs have tapered side edges which present ingress openings for entry of hairs to be cut.

3. The clipper recited in claim 1 wherein the casing has slot means through which the grip means extend.

4.
