DOUBLE-EDGE COMBINATION DRY SHAVER AND FINISHING HAIR CLIPPER WITH ADJUSTABLE HEAD Filed oct. 28, 1964- I N VE NTOR. /l//f//f/r iva/5 United States Patent() 3,279,056 DOUBLE-EDGE COMBINATION DRY SHAVER AND FINISHING HAIR` CLIPPER WITH AD- JUSTABLE HEAD Mathew Andis, Racine, Wis., assignor to Andis Clipper Co., Racine, Wis., a corporation of Wisconsin Filed Oct. 28, 1964, Ser. No. 407,024 2 Claims. (Cl. 30-34.1)
This invention relates to a double-edge combination dry shaver and lnishing hair clipper with adjustable head.
The device of the present invention may be regarded as a hair clipper and dry shaver combined in one instrument so that the same instrument may be usde as a nisher for hair trimming and shaving, .thus eliminating accessory equipment such -as a straight edge razor, soap, towels, etc. and the operations commonly employed in connection therewith.
'I'he motor case, which serves as a handle, is symmet-tical and the clipping head with its .double edged comb .and cutter blades is swiveled thereto on a transverse axis so that either edge of the blade may be positioned at the conventional 30 angle to the casing.
The comb blade has an open side which desirably has teeth which, by way of example, are of 4t-he pitch and thickness of .a regular No. 0000 blade of approximately 1/32 pitch and .010 inch thickness vi-n the a-rea of the cut. Some years ago, these dimensions were adapted by several clipper manufactures as standard for such a blade.
Along its other side, the comb blade may 'be closed Vand may have liner teeth, or may have perforations in its intermediate area, or may have such perforations and also minute notches along bot'h margins which may be regarded as teeth of minimum extent. The preferred arrangement .is such that the closed side of the comb blade constitutes .a iiange which extends substantially at right angles to the face of the blade and into which the teeth extend so that the comb blade can be used on edge to -work -in limited space.
The cylindrical swivelling mechanism which mounts the head on the clipper case has a shield for excluding hair and has means for providing braking friction to hold the head in adjusted position. There is a universal swivel between the driving arm of the motor and the driven part of the vibratory blade and 4an arrangement whereby a spring on the arm provides uniform tension on the cutter in all positions of adjustment of the head.
In lthe drawings:
FIG. 1 is a fragmentary view .taken in section on the .line 1-1 of FIG. 3.
FIG. 2 is a fragment-ary detail view taken in section on the line 2-2 of FIG. 3.
FIG 3 is a fragmentary detail view in section taken on the line 3 3 of FIG. 1.
FIG. 4 is a view similar to FIG. 3 showing the head swiveled to one of its operating positions.
FIG. 5 is a view in side elevation of the par-ts shown in FIG. 3.
FIG. 6 is a fragmentary detail view on an enlarged scale of the comb blade shown in F'IG. 5 as viewed in the plane indicated at 6-6 in FIG. 5.
FIG. 7 is a view similar to FIG. 6 showing a modified comb blade structure.
FIG. 8 lis a fragmentary detail view in perspective showing a further modified embodiment.
'I'he clipper case .'10 which also serves as a handle contains a driving motor of which only the vibratory armature 12 is illustrated. Bracket Iarms 14 and 1.6 screwed to the sides of the case .10 have registering apertures 18 for the bearing trunnions 20 at .the ends of the swiveled head 22. 'Ihe cylindrical periphery of the hea-d is re- 3,279,056 Patented Oct. 18, 1966 ICC lieved and provides shoulders 2-4 and 26 engaged with the side margins of the semi-tubular hair-guard 28 which in interposed between the generally cylindrical bearing surface 30 of the head and the complementary bearing surface 32 of the case ('FIG. 3). The hair-guard is prefer-ably made of stainless steel.
The arcuate extent of the hair guard 28 is less than that of lthe bea-ring surface 30. A slot 36 in the hairguard clears the blade driving arm 38. As the head 22 is swiveled from side to side, the hair-guard 28 -is picked up by one of the shoulders 24 4or 26 .to partake of the swivelling movement and to limit the swivelling movement when the end -of the slot 36 is reached. The fact that the hair-guard has less angular extent than the bearing surface 30 provides .a cer-tain degree of lost motion between the hair guard and the head. Consequently, in the ret-urn swivelling movement of the head, .the guard remains stationary until picked up by the opposite shoulder. This arrangement assures the exclusion of hair from the interior of lthe head in -all positions of the head.
Bias of .the slightly resilient bracket arms 14 and 16 pressing against the ends of the oscillatory head 22 serves to maintain the head subject to submission braking pressure to hold it in any -selected position of adjustment. Normally, the head is placed in one or another of extreme positions of angular adjustment.
The double-edged comb blade 40 is of channel-shaped cross section as clearly appears in FIGS. 3, 4, 5 and 8. At its open side, it has a lia-nge 42 having teeth 44 which, in the instant exempliiication of the invention, may lbe assumed, illustra-tively, to be the comb teeth of a conventional 0000 clipper. These are of approximately 1/32 inch in pitch and .010 inch thickness in the area between the terminal .teeth 46, the latter being of somewhat increased thickness in the preferred embodiment.
At -the so-called closed side, the comb bla-de 40 h-as a flange 48 which may be provided with extremely ne shaver teeth at 50 (FIG. 6) .or with shaver openings 52 (FIG. 7) or with a combination of openings 52 and very line notches at 54 and 56 which serve as teeth (IFIG. 8). 'In any case, it is desired that the margins at the ends of the ange 48 be thickened as shown at 58 in FIGS. 6, 7 and 8, to take the pressure and enable the user to make a closer cut Without danger of injury to the skin.
For connecting the channel-shaped comb blade 40 to the head 22, I use screws 60 which pass through a nonmetallic bearing member 62 into bosses 64 which project from the head 22. The bosses extend through slots 66 in the vibratory shear blade 68. This blade is channelshaped (FIG. 4) and is guided on the side and top surfaces of member 62. The vibratory shear blade 68 has toothed flanges 70 #and 72, respectively complementary to anges 42 and 48 of the shear blade 40.
For transmitting motion from the armature 12 to the vibratory blade 68, the post 38 which projects from the armature 12 is provided with a terminal ball 74, the center of which preferably lies on the transverse axis of oscillation of the cylindrical head 22. The post 38 is tapered at 76 in approaching the ball 74. Embracing the ball is a bifurcated socket 78 at the end of fitting 80, which is screwed to the center of the vibratory blade 68 (FIGS. 2, 3 and 4). Externally, the `socket 78 is likewise spherical and engaged by a hollow cap 82 concentric with post 38. The cap floats on the post and transmits to the tting 80 the bias of a compression spring 84 which encircles the post. Because of the coaxial arrangement of the parts, the bias transmitted through the cap 82 and fitting 80 to the blade 68 maintains blade tension substantially constant in .all positions of oscillatory adjustment of the head.
The procedure in nishing -a hair cut involves two stages of operation as follows:
First: The operator swivels the blade head to the position shown in FIGS. 4 and 5 with the open teeth of flange 42 of the comb blade 40 directed outwardly. With the handle so held that the teeth are approximately at right angles to the surface of the skin, the blade is guided along the edge of the area to be outlined. After outlining is completed, the teeth are placed in faceV contact with the skin and the device functions as a clipper, all hair outside of the outlined area being removed by clipping, leaving hair -as stubble which, in the assumed dimensions of the parts, will have the approximate length of .010 inch.
Second: The head is now thrown to its other extreme of movement in which the closed side of the blade yis directed outwardly from the handle. The perforated surface is now held yin face contact with the skin and guided over the area previously clipped to shave off the stubble of approximately .010 inch left by the clipping above described. Only the stubble which is shorter'than vthe diameter of the perforations 52 will be received readily into multiple perforations. The hair in this category will be clipped close to the skin.V The longer hair` at the edge of the outline will bend when contacted by the leading edge of the closed m-argin of flange 48 and will not enter the perforations and therefore will remain uncut. It will be understood that for this operation the yform of the blade `show nin FIG. 7 is perferred to the forms shown yin FIGS. 6 or 8.
It will, of course, be understood that various other combinations of blade dimensions and pitch may be substituted.
