BURTON J. LIPMAN BY ATTORNEYS Patented Aug. .24, 1954 UNITED STATES PATENT OFFICE 2,686,965 HAIR CLIPPER Burton J. Lipman, University City, Mo. Application January 8, 1954, Serial No. 402,911

This invention relates generally to improvements in a hair clipper, and more particularly to improvements in a hair-cutting device adapted to remove hair growth from small cavities such as the nostrils or car openings.

An important object of the present improvements is to realize a clipper device for the purposes mentioned which may be easily and ac curately operated by one hand to efiect removal of hair from nostril or car cavities with precision and without any danger of severing the skin. Briefly stated, the device is comprised of atubular body having an end portion of reduced cross sectional area, the end portion having a plurality of slots, and a plunger reciprocably reviding a series of particularly arranged slots in a 10 Claims. (Cl. 30-29.5)

tubular portion of the hair-cutting device, and

in providing a cutting head having a sharp peripheral cutting edge adapted to wipe the edges defining the slots to sever the hairs incident to forward longitudinal movement of the head. An other advantage is afforded in the provision of a dished formation in the cutting head immediately adjacent the cutting edge which is adapted to collect the hairs after severance, thus clearing the cutting edge and slots for subsequent hair I cutting action upon reciprocable actuation of the head, the structural arrangement afiording a self-cleaning efiect.

A still further important object is to provide a clipper device that is simple and durable in construction, is inexpensive to manufacture, and which consistsof relatively few parts that may be quickly and easily assembled for precise and efiicient operation.

The foregoing and numerous other objects of the invention will more clearly appear from the following detailed description of a presently preferred embodiment, particularly when considered in connection with the accompanying drawing, in which:

Fig. 1 is an enlarged the hair clipper;

Fig. 2 is a longitudinal sectional view as taken along line 2-2 of Fig. 1;

Fig. 3 is a view in cross section as taken along line 33 of Fig. 1, and

side elevational view of Fig. 4 is a perspective view of the cutting head and connecting rod of the plunger mechanism.

Referring now by characters of reference to thedrawing, and first to Figs. 1 and 2, it will be apparent that the hair-cutting device, generally indicated at I0, consists partly of a tubular body II having a forward end portion I2 of relatively reduced diameter. The tubular body II is provided with a shoulder l3 (Fig. 2), and a depressed annular-bead I4 slightly spaced from shoulder I3. A washer I5 is located between and secured by shoulder I3 and bead I4, the washer I5 defining the rear of reduced end portion I2. Additional purposes and functions of washer I5 are later described in detail.

The end portion I2 of tubular body II is provided with a plurality of elongate slots: I6, the slots I6 being arranged in a predetermined regular pattern of four longitudinal rows. As is more clearly shown by Fig. 3, the rows of slots I5 areequidistantly spaced around tubular end portion [2. Each slot I5 of each row is located directly opposite a corresponding slot I6 of each adjacent row, and each slot I6 is disposed so that the side edges defining the slots are arranged obliquely to the longitudinal axis of tubular body I I.

A plunger mechanism, generally referred to at I1, is slidably received and mounted for recipro-.

cable actuation in tubular body I I. The plunger II includes a cylindrical cutting head 20 that closely fits the bore of reduced end portion I2. Formed integral with cutting head 20, is a connecting rod 2| that extends rearwardly through a central aperture provided in washer I5. The rear end of rod 2I is provided with threads 22 for threaded connection to an actuating button 23. It will be noted that button 23 is of a diameter that closely approximates the internal diameter of tubular body II, and isslidably received therein.

The button 23 is provided with an annular shoulder 24 that constitutes a thumb rest, and that coacts with ,the rear end of tubular body I I to limit the extent of retraction of th plunger mechanism IT. A compression spring 25 is located in tubular body I I, one. end of which abuts washer I 5, while the opposite end seats on the forward end of button 23, the spring 25 being arranged about rod 2|. Normally the spring 25 acts to urge the plunger mechanism I7, and hence cutting head 20 rearwardly to the position shown in Fig. 2. In this extended position,

the rear portion of cutting head 20 abuts washer I 5, and hence head 20 is confined to operation in reduced end portion I2.

To enable one hand operation of the hair-cutting device, the rear end of tubular body I I is provided with an annular flange 26 that is of sufficient dimensions to be gripped between the first two fingers of the hand. When flange 26 is gripped in the manner described above, the button 23 may be depressed by the thumb along the longitudinal axis against the loading of spring 25 until shoulder 24 abuts flange 26. The outer surface of tubular body ll may be knurled in the region adjacent flange 26. as is shown in Fig. l, to afford a more-effective grip for the fingers.

The cutting head 20 includes a sharp, periph eral cutting edge 21 along its forward margin.

which is adapted to wipe the lateral edges defining slots 16 so as to sever hair projecting through the slots and into reduced end portion l2. From the perspective view of Fig. 4, it is seen that the forward portion of cutting head 28 is provided with a concave dished formation 39 immediately adjacent peripheral cutting edge 21, the formation 30 being adapted to collect the hair after severance by cutting edge 21, hence acting to clear slots l6 and edge 21 to realize a se1f-cleaning eifect.

The operation and functional use of the device is thought to have become fully apparent from the foregoing detailed description, but for completeness of disclosure, it will be noted that tubular body II is gripped between the first two fingers, and button 23 is actuated by the thumb. The'reduced end portion I2 is inserted into the nostril, and the button 23 is depressed. As a result, head 20 is moved longitudinally forward so that cutting edge 21 wipes the edge defining slots 16, hence severing hairs projecting into slotted end portion [2. The severed hairs fall into dished formation 30, and are collected for subsequent removal. After head 28 reaches the end of its forward cutting stroke, as determined by engagement of shoulder 24 with flange 26, the button .23 is released by the thumb. Consequently, the spring .25 acts to return cutting head 21] and button 23- to the extended position shown by Fig. 2. .It is seen thatas button 23 is actuated by the thumb, the cutting head 20 is reciprocably moved in slotted end portion 12. After removal of end portion.l2.from the nostril, the head 29 may be moved to its .forwardmost position in end portion [2,.and the hairs emptied-from dished formation 30 through the open forward end of tubular portion l2.

Although the invention has been described by making detailed reference to a single preferred embodiment, such detail is'to be understood in an instructive, rather than in any restrictive sense, many variants being possible within the scope of the claims hereunto appended.
