HAIR cLiPPER Application led November 3, 1927. Serial No.` 230,728.

The purpose of this invention is to provide an `improved device for barbers use in trime `ming customers7 hair particularly adapted for graduating t-he closeness of thecut, from the shortest possible to a substantial length,

withoutthe necessity for using comb and shears, but by varying the tilt of thev clipper as it is advanced over the head.Y The invention consists in the elementsand features of 1o construction shown and describedy as vindicated in the claims. In the drawings:

Figure `1 is a side elevation of a hair clipper equipped-with this invention.

Figure 2 is a top plan view ofthe same. Figure 3 is a bottom plan view. Figure 4 is la section at the line 4-4 on Figure 2 on an enlarged scale.

Figure 5 is a detail section at the line 5--5 on Figure 4.

Figure 6 is a perspective view of the attachment which is applied to acommon form of clipper.

Figure 7 is a section at the plane indicated by theline 77 on Figure 2.

Figure 8 is a view similar toVV Figure 1 showing the inventionY in a modied form 'suited for attachment to a clipper'of slightly C, mounted upon the upper side of thefixed 40 cuttergand, comb, B, said reciprocating blade being connected for operation in-any familiar A manner as by the pivoted operating handle, C1. The bottom sideof thekmember, A, with the fixed cutter and comb, B, invplace thereon,-is shown as having the-usual fiat face from the heel forward to what may -be considered as the tooth zone at which it is beveled sloping upward to the points ofthe teeth at an oblique angle of aboutlGOoto the-rear flat part. The reciprocating cutter is also lshown tourk continuing in direction tangential to the .cutter blade.v This upper comb as seen at E,

wardly. 'from its rearmost and uppermost in the usual form,;fiat on the under side for matingproperly with the flat upper face of the fixed cutter and comb,iand tapered thickening from the points of the teeth rearward slightly beyond the roots ofthe teeth, For4 55 4adapting the clipper to the mode of use indicated above,-making a graduated cut without lifting it from the head Vand carrying it .without support,-there is provided what is termed a rocker shown at D, which is app plied to the flat bottom of the fixed cutter and comb, B, and is curved fore-and-aft, convex downwardly under the heel of the body, with the forward part of its fore-and-aft conconvex curve of the rear part forwardly to Y.the angle at which the under side bevel of the xed cutter begins.` AThis rocker, D, is shown as a sheet metal stamping formed with upstanding iianges,D1-D1, at its opposite sides spaced apart suitably for embracing the body of the clipper and the fixed cutter and comb,

Y B, thereon, snuglyand so as to be secure againstdisplacement; and for such security there is struckfrom each of the flanges,

Di-D1, a lug d1, which is clinched over the end of the fixed vcutter j ust back of the tooth zone, as seen atd10.

- A .characteristic feature of this invention is the provision of an upper comb, that is, a` comb whose comb teeth extend above the Vreciprocating cutter in vertical registration respectively with teeth of the fixed cutter and conib which extends below the reciprocating is mounted on the upper forward end portion -of the flanges, Ble-D1, as geen at 2 2 which representr inwardly flexed lips -or tongues engaging grooves, e2-e2, which are formed in the endv edges of the upper connlo,` E, which is therebyslidably engaged with and supported by the flanges, D1-D1, of the rocker, VD.V It will rbe noted that the upper forward ends of the flanges, D1-D1, Awhich are folded as describedto form the lips, d2, en-v gaging Vthe grooves, e2, of the upper comb, ,are inclined at an angle of about 30 tothe `plane of the cut; and that thereby the upper cutter is rendered adjustable downwardforposition, at the angle mentioned to the plane of the cut, thereby carrying the points of the teeth of said upper comb to a greater or less degree forward of the line of the cut and below the plane of the cut. r.lhe teeth of the upper comb are preferably spaced apart to register in vertical planes with the alternate teeth of the lower xed comb, B; and extending from above the reciprocating comb for-V ward and downwardly as indicated, their overhanging ends projecting beyond the lower fixed comb teeth with which they respectively register; and said upper comb teeth are preferably formed each with j a slight shoulder at the under side, as seen at e, which at the rearmost adjustment of the up per comb are in touch with the points of the lower comb teeth respectively, which as usual project slightly beyond the points of the teeth of the reciprocating cutter. For holding the upper comb at any position to which it may be adjusted by sliding at the tongue and groove engagement described, the edges of the lips, e2, are provided with a succession of rounded indentations seen at e3, and a slight lug or tooth, d3, is struck and folded inwardly from the bottom of each of the grooves, (Z2, for engaging the serrations,

c3, the flanges, (Z1, being sufficiently resilient to permit their yielding outwardly as the teeth, da, ride up overY the slight up raise between the indentations. The distance occupied by the entire series of indentations is designed to permit a range of adjustment of the upper comb down forwardly from the position at which the shoulders, e4, of the teeth are in touch with the points of the teeth of the lower fixed comb, to a plane tangent to the curve of the rocker as far below the line of cut as the maximum length of the shortest stubble to be left by the clipper, that is, the length to be produced at the beginning of the stroke or advance movement over the head, as, from the back of the neck up over the back of the head.

It may be understood from the foregoing description that in the use of a clipper equipped with this invention the barber will rst adjust the upper comb in its slideways acording to the closeness of the clip which he intends to make, and it will be seen that when adjusted to the rearmost and the uppermost position, with the points of the lower comb teeth in touch with the shoulders, e4, of the upper comb teeth, the clip will be as close as can possibly be made, the length of the stubble being only the thickness of the teeth of the lower` fixed cutter and comb at the line of out; and that the adjustment of the upper comb from this position forward and downward will lengthen the stubble according to the adjustment. And it will be understood that in advancing the clipper over the head by gradually tilting it over the rocker for lifting the forward points from the scalp, the teeth of the upper comb will pick up the hair in little sheaves between the teeth, holding it lifted in advance of the line of cut in the manner in which the barber using comb and shears lifts the hair with the comb in advance of the shears, that is, clipping the hair behind the comb;` and that in similar manner the reciprocating blade'with its line of cut back of the sheath of hairs upliftedby the upper comb with its teeth extendingiforwardly of the line of cut, severs the uplifted hairs just as the shears sever the uplifted hairs behind the comb carried by the barbers left hand while he manipulates the shears with his right hand. To facilitate the lifting of the hair in little sheaves, as described, by the upper comb teeth, said teeth are beveled on both lateral edges narrowing the f teeth upwardly and widening upwardly the gaps between them, so that the group of hairs picked up between any two consecutive teeth naturally tend to fan out in the widening gap between the teeth, thereby giving the teeth a slight under hold on the hairs by which the hairs will be lifted further than they would otherwise be before they drop back in the gap between the comb teeth and into the grasp of the teeth of the reciprocating cutter.

In Figure 8 there is shown a clipper of slightly di'erent form,-formed with convex or rocker bottom instead of the flat bottom of the forms shown in the previous figures, this form, therefore, not requiring the application of the rocker to adapt it to the mode of action above described. For this type of clipper the upper comb, F, is conveniently mounted directly upon the upper side of the comb body, as, on the cap or cover, G, as seen at g1, which represents a slight boss formed on the cover for receiving grooves, g2, in its lateral edges, the upper comb, F, being formed with a deep recess in its rear edge rendering it forked, the edges of the fork members, f2,

fitting slidingly in the grooves, g2, which are inclined down forwardly at substantially the inclination shown with respect to the tongue and groove engagement of the upper comb of the form shown in the preceding figures. In this form (Figure 8) the upper comb has its comb teeth, f, extending above the teeth of the reciprocating cutter and forwardly thereof with a slight shoulder, f3, at the under side which at the rearmost adjustment of said upper comb, F, is in touch with the points of the teeth of the fixed cutter, as in the form shown in the preceding figures. For holding the upper comb, F, in adjusted position, a tongue, f4, is extended rearward between the fork arms, f2, into an undercut adapted to receive it in the boss, g1, and this tongue isv provided upon its upper face with a series of indentations, f5, adapted to be engaged with a small set screw, g5, set through the upper side of the boss, g1, over said undercut.
