9 Claims.

This invention relates to improvements in hair clipping devices; and the main object of my invention is to provide a clipper which shall be adapted for ready and accurate trim clipping of hair or bristles growing in the ears and nostrils. Further objects are to provide such clippers adapted to better facilitate trimming moustaches, beards and sideburns; to provide such a clipper of relatively small Size and which cannot out or irritate the skin; to provide a unitary clipper construction of this character which comprises a lower stationary member and a reciprocating upper member and each of the members having comblike side edges; and to provide a device of this character which shall be simple in construction and operation and relatively inexpensive to manufacture. A special object is to guard against occasion for piucking out nasal hairs by the roots and the possible consequence of dangerous infections.

Illustrative embodiments of this invention are shown in the accompanying drawings in which:

Figure 1 is a top plan view of my improved clipper approximating actual size.

Fig. 2 is an enlarged sectional View taken on the line 2--2 of Fig. l.

Figs. 3 and 4 are enlarged sectional views taken on the lines 3-3 and 4-4, respectively, of Fig. 2.

Fig. 5 is a top plan view of a modied form of construction embodying my invention.

Figs. l0 and 1l are perspective views of the two forms described above but illustrating a manual operating means. These views are approximately the actual size of the clipper.

Fig. 12 is an enlarged cross-sectional view taken on the line I2-I2 of Fig. ll.

Referring to the embodiment shown in Figs. l to 4, inclusive, the invention comprises a handle I having a power unit such as a motor or vibrator (not shown) of any well-known form, embodied therein, a lower stationary skin contacting mem` ber 2, and an upper movable cutter member 3.

The two members 2 and 3 are preferably constructed of a high grade of tempered steel and they are each provided with a comb comprising a series oi slots 4 and 5 respectively, extending inwardly from the free edges of said members to form teeth 6 and 1, respectively. The member 2 is provided with a tongue 8 which is adapted to be inserted in the aperture 9 located in the end of the handle I, and secured therein by any suitable means such as by a set screw I0.

The cutter member 3 is also provided with an integrally `formed tongue Il adapted for insertion in the aperture I2 located in the end of handle I. The apertures 9 and I2 both lie in the same vertical plane. The aperture I2 is only large enough tot readily accommodate the tongue I I and provide for a free fore-and-aft lengthwise movement of the tongue Il. The tongue Il has an aperture I3 into which one` end of the power shaft arm I4 is adapted to seat. The other end of the arm is connected to the motor or vibrator, not shown, located in the handle, for operation by the motor, so that as it is repeatedly vibrated by the motor, the upper member 3 is reciprocated against the stationary member 2.

The upper member 3 is also provided with an elongated slot I5 into which is placed a bearing or spacer block I6 having an aperture I1 through which the machine screw I8 is inserted for engagement into the threaded aperture I9 of the lower member 2. A bowed spring 20 is positioned on the block I6 and member 3, and held thereon by the bearing head 2l of set screw I8. As the spring is bowed downwardly so that the free 4ends of the same bear against the upper surface of member 3 it can readily be apparent that the member 3 will be positioned on the member 2 at all times for cooperation therewith. As the slot I5 is longer than the length of the block I6 the member 3 is free to reciprocate against the member 2 at all times.

As will be seen from Fig. 3 of the drawings, the members 2 and 3 are arcuate-shaped in crosssection so that the outer ends of teeth 6--1 come to a point at the side edges of the members to provide suitable comb-like fingers into which the hair to be clipped may readily enter and be clipped by the reciprocating movement of member 3.

Referring to the embodiment shown in Figs. 5 to 9, the lower or stationary member 22 is formed from a blank and is punched or otherwise bent substantially in a U-shape with the bottom bulged outwardly and the side walls disposed substantially in a perpendicular plane as shown in crosssection in Figs. 'l and 8.

The upper or movable cutter member 23 is also bent in a substantially U-shape and is smaller in cross-sectional area than the member 22 as is apparent from Figs. 'l and 8. The member 23 is adapted to be placed inside the side walls of the member 22 and held therebetween by bolt 24 which extends through apertures 5 in the side walls of member 22 and through the slots 28 in the side walls of member 23.

I'he members 22 and 23 are provided with tongue parts 21 and 28 respectively, which function in the same manner and are secured to the handle in the manner as tongues 8 and Il of the embodiment shown in Figs. 1 to 4 inclusive. Each of the members 22 and 23 is provided with slots and teeth 29--39 and 3l-32 respectively, and are identical in every respect with the teeth and slots 6 7 and @-5 of members 2 3 respectively. The member 22 is also'y provided with several elongated slots 33 to substantially lighten the weight of the clipper.

In the embodiments shown in Figs. 10 and 11 the motor or vibrator illustrated in Figs. 1 and 5 is eliminated and a manual power means provided.

This manual power means consists of a pair of handle bars 3ft-35 each hingedly connected at Saws? to an end block 38. The block 38 is provided with a slot 3i) into which the tongle 2l is adapted to be inserted and secured therein by any suitable means such as a set screw I in the same manner as shown and described for attachment of the tongues 8 and 21 to the handle I. The tongues il and 28' are especially elongated for use in the manually operated devices of Figs. 10 and 11 so that the free ends thereof may be inserted through the slots l2 and be pivotally or otherwise secured to one end of each of the links lll of the handle bars 3&5-35 respectively. The other ends of links 4E) are pivotally or otherwise secured to brackets 4i which are formed by striking out a portion of handle bars 34-35 and bending such portions inwardly at right angles thereto, as clearly shown in Figs. l0 and 1l. A bearing l2 is provided on the block 33 and a cooperating bearing or collar 43 is secured to the tongue 28 adjacent the: free end thereof. A compression spring 44 is placed around the tongue 28 and between the bearings S2-d3.

It will be apparent that by applying inward pressure on the handle bars Sil-35, the links di) will tend to force the inner member 23 outwardly, away from the bearing block 33, thereby reciprocating the teeth thereof against the teeth of the stationary member 22. Upon release of the pressure applied to the handles Sil-35 the spring i4 will tend to return the member 23 to its starting position. rIhe movement of the cutter member 23 need be only a small fraction of an inch because of the minuteness of the teeth and slots of the cutter and stationary members.

It is to be understood that the prime numbers applied to Fig. 10 correspond to like parts of the construction shown in Figs. 1 to 4 inclusive and the numerals not primed applied to Fig. l1 correspond to like numerals in Fig. y10.

Referring especially to Figs. to 9, it is to benoted that the two shear members or cutters, are Ll-shaped in cross-section, one being i'lxed `and the other slidable, and that they constitute substantially a pair of U-combs one embracing the other with their teeth disposed for mutual shear cutting.

It will be understood that some of the details set forth may be altered or omitted without departing from the spirit ofthe invention as dened by the following claims.
