The presentinvention relates to a comb mounting: attachment for hair clippers and constitutes animprovement of the arrangement shown in myPatent' No. 2,381,046,issued August '7, 1945. In the present arrangement the comb attachment is so constructed and arranged that it may be mounted on hair clipper heads of a variety of types.

I-Iair' clippers, as is well known to the trade and barber profession, have cutter heads that differ as to their shapes and dimensions. This is particularly true respecting the width of the fixed comb platein the clipper head across which the cutter plate oscillates with a rapid vibratory motion for effecting the cutting operations. H'encefa comb attachment: which is sold to the trade generally, shouldpossess effective and easily operated means to render it capable of ready installation on a variety of hair clippers produced 'and distributed by different manufacturersz To this end I have inventeda removable comb mounting structure that is characterized by its adaptability for "quick assembly with theclipper heads which are generally avail able on the market.

Iti's'therefore the primary object of my present invention to improve the construction ofa comb attachment for hair clippers, and to amplify the efficiency, operation and dependability of an attachment of this character.

Also, it is a principal object hereof to provide mounting means for attaching a supplementary comb-on'a hair clipper; which means are capable of'maximum adjustability of its means for securing-it detachably tocutter heads of" clippers having 'diiferent widths. Differently stated, I have provided a comb attachingstructure having' universal adjustment.

Another object is to provide dependable and easily operated means whereby the auxiliary dependably shifted tocomb'maybe quickly and various positions relative to the comb plate of the clipper head, and be positively maintained in any adjusted position without liability of slippage;

Aifurtherobj'ect. hereof resides in the provisionof an adjustable combattachment of such character that it does not interfere with the usual working parts of the clipper head to which it is attached.

Also the. presentsimprovementsz provide a comb mounting structure that is constructed of, sturdy parts so that, at all times, it-will operate-in a dependablezmanner and will not readily get out, of Furthermore, the present. arrangement 2 issuch that'the parts may be. produced inthe form of metal stampings, and which may be as.- sembled in an economical manner, with the. result that the attachment may be soldv for a reasonable price to retail trade.

Additional objects, aims and advantages of the improvements contemplated hereinwill be ap-. parent to persons skilled in the art after the construction and operation of the comb attachment is understood from the within description.

It is preferred to accomplish the numerous objects of my present invention, and to practice the same, in substantially the manner hereinafter fully described and as more. particularly pointed out or defined in the appended claims.- Reference. is now made to. the accompanying drawings that form a part of the specification.

In the drawings:

Fig. 1 is a sideelevation of my improved comb. attachment shown assembled with the cutter head or distal portion of a hair clipper, andv drawn to an enlarged scale;

Fig. 2 is a top plan of the attachment removed from the clipper head;

Fig. 3 is a face view looking at the structure on the plane of line 3-4 on Fig. 1, portions being broken away for clearness;

Fig- 4 is a section taken along the plane of line 4-4- on Fig. 2;

Fig. 5 is a-sect-iontaken along the plane of. line. 5-5 on Fig. 2;

Fig. 6 is a transverse. section on Fig. 2, taken along line -6- -6 thereon; and

Fig- '7- isa fragmentary sectional view along the plane of line 1- l on, Fig. 4.

Thewdrawings are to be understood as being more or less of a schematic. character for the purpose of disclosing a typical or preferred form of the invention contemplated herein. In said drawings, like reference characters identify thev same parts in the different views.

The work performing end, or distal portion of the. hair clipper illustrated in Fig. 1, includes a head assembly In, at the; cutting end of a. conveniently shaped housing or body H that en,- closes a small electricv motor unit of any desired type for operating the. vibratory cutter l2 in an oscillatory movement along oracross a comb plate l3 which may be securely anchored for intimate. cooperation with the cutter. the ends of the comb. plate l3. project beyond or slightly overhang the side walls of the housing body, and so far-as I am aware, this isa charac-..

teristic of amajority of the well-known makes of hair clippers at. present available.. These. clip-.1

AS. seen,

ment the clipper body and cuttinghead may be bodily tilted with respect to the scalp during the cutting of the hair, which permits the length of the severed hair to be varied. Also the tilting may be progressively increased or diminished during the cutting operation, according to the judgment of the operator and the type of haircut being given to individual customers.

The structure for mounting the auxiliary comb on the clipper is in the form of a composite unit which comprises a main plate or base member I4 of a generally rectangular or oblong shape having tapered side flanges I5 theheight of which diminish towards the forward edge of plate I4. Theseside flanges I 5 have inclined slots I6 preferably paralleling the outer edges of said flanges so that they are oblique to the and have ears 26 at their'ends which are provided with finger grasping buttons 27. The other or forward portions of rocker levers 24, 24 (which are identified as 24a), taper towards their ends which are positioned against the studs 2I on the sliding clamps I9. It will be seen that each lever takes the general form of a bell-crank, with the forward portion at an oblique angle to the rear portion, and are fulcrumed at the junctions of these angles.

By reason of the construction and arrangement above-described, the clamp operating mem- 7 bers are of a scissors type wherein the rear arms plane of the plate I4,, the purpose of these slots will later be explained. At the rear of said plate there is a stop or abutment I'I adapted for engagement with the rear edge of the clipper comb I3 as seen in Fig. 1 to assist in desirably positioning the assembly and maintain it on the clipper head.

There is an elongated rectangular shallow walled guide I8 at the forward region of the main plate I4, said guide beingof hollow form which is open at its ends sothat it accommodates the elongated flat portions of a pair of oppositely movable clamp members I9 which have sliding movement in said guide I8. 7 The ends of clamp members I9 protrude through the open ends of guide I8 and are bent transversely in the form of flattened L -shaped jaws 20 which have their inwardly projecting portions in planes oblique to the planes of the upstanding portion. Yieldable cushions or pads 20a, preferably of rubber or the like, are cemented or otherwise secured to the inner faces of laws 2!! to absorb vibration as well as to insure a firm gripping of the jaws against the ends of the clipper comb plate of a variety of thicknesses. This arrangement comprises an important feature of the improvement for itis apparent that to provide a device having universal adjustability, the clamps should be of a character which adapts them to engage different types of clipper head members.

As, seen more clearly in Figs. 2, 4 and 6, the proximate inner regions of clamps I9 have studs 2!, 2|, secured to them, and the upper and lower walls of guide I8 are slotted as at 22 and 23 respectively to accommodate the upset ends and shanks of said studs. The studs 2i comprise portions of an operating mechanism which is adapted to move the clamp members I9 reciprocably in guide I8. This operating mechanism also includes a pair of rocking

levers

24, 24 arranged in superimposed relation to each other beneath body plate I4. and are. fulcrumed intermediate their ends on a headed pivot pin 25 projecting downward from the rear portion of plate I cl in themanner shown in Fig. 6. The rear portions of levers 24 project beyond the rear edge of plate I4 where they are deflected obliquely as shown,

of the levers are urged in spaced apart relation by yieldable means such as spring members 28 which are anchored to pins 29 on plate I 4 and have their free ends bearing against studs 2| of the sliding clamps IS. Said spring members 28 are of suiiicient tension to urge clamps I9 towards each other in a manner to cause the jaws 20 of the clamps to firmly engage the sides of the clipper comb I3 and prevent dislodgement of the attachment while in use. Furthermore, the arrangement described adapts the attachment for being dependably mounted on hair clippers having comb plates or other members of a variety of lengths. The operation of mounting this attachment to a hair clipper is a very simple one which requires merely the pressing of the finger buttons 21 towards each other which moves the clamps [9 in an outward direction far enough to permit placement of the clipper comb or other member between the jaws 2B, whereupon by releasing the manual flnger pressure the jaws will be retracted by'springs 28 into firm engagement with the portion of the clipper to which the attachment is releasably secured.

The portion of this assembly which carries the auxiliary combfor'coaction with the comb of the clipper head In preferably takes the form of a slide which is adapted to be locked in a plurality of selected positions, and while in any of these positions theclipper head may be tilted with respect to the auxiliary comb to predetermine the length of hair removed by the clipper. This auxiliary comb carrier preferably comprises a generally rectangular holder 30 each side margin of which has at least two spaced L-shaped lugs 3I arranged with their lateral portions turned inward towards the lugs at the opposite edge of holder 30 as best seen in Fig. 4 wherein the auxiliary comb 32 is shown in broken lines. The back-- bone of comb 32 has a recess 33 adjacent its margin into which is projected a latch pin 34 ona flat spring 35 anchored to holder plate 30 (Figs. 1 and 3), and leading to recess 33 there is an inclined groove 36 for guiding pin 34 to said recess when the comb 32 is inserted edgewise into lugs 3|. Thus the comb is releasably held in position in holder 30 to permit its ready removal for cleaning or replacement whenever desired.

Holder 30 has ears 3! at its sides preferably lying against the inner surfaces of the slotted side flanges l5 on the main plate or base member l4 and have a generally triangular or tapered contour. Headed pivots 38 pass through ears 31 to provide fulcrums for comb holder 30'and have their shanks 'slidably engaged in the 1 inclined slots I6 hereinbefore mentioned. The'pivots 33 have long shanks which project inward of ears 3'! and are surrounded by the convolutions of and main plate l4, the convoluted portions of said springs being maintained on the pivot shanks by i retainer washerssm.as; shown in. detail on Fig. 4. Thesexsprings-yieldably urge-:the leadingeedge of holderrm andrthe toothedgportiona of the-comb 312 towardsthe cutter-portion of the. clipper head in t-ne manner. shown inliigs. .1 and'G; This, ar rangement-is eifective to;,p,ermit yielding tilting movement between the comb attachment and the hair clipper during the hair cutting operation, suchatilting movement being for the purpose of determining the length of hair removed as will be later explained; e

Inaddition providing this aforesaid tiltability the assembly has means wherebythecomb holder 30 m y emcvedbcdily n he. suidesl s it for the purpose of projecting or retracting the tips of the; comb teeth with relation to the. clipper headcombl 13,. said .meansbeingadapted to, releasably lock thecomb. holder st, in any, of its adii stedapositions... These;me an s comprise latch armed-l located alongside the flanges lion the ends cfhol'derplatei said latch arms bein f crumed at their forward ends on pivot pins d2 projecting outward from flanges I5. At their rear ends these arms are joined by a fiat cross bar 43 which reinforces said arms and permits simultaneous movement thereof. Finger washers or buttons 44 are secured to the free ends of latch arms M and said arms are serrated to provide a plurality of notches or recesses d5 along their outer edges for latching engagement with the pivot pins 38 alongside the heads of said pins. The latch arms GI are urged towards pivot pins 38 by springs 46 the outer regions of which press against said latch arms while the other ends of said springs 46 are anchored to a convenient portion of the assembly preferably to studs i"; the abutment or stop flange IT at the rear of the main plate It above the levers 24. This permits movement of the latch arms in a direction away from pivots 38 thereby releasing the comb holder 34 so that it may be bodily moved outwardly of the clipper head H3 or retracted therefrom the distance'desired for cutting the hair. In any of these adjusted positions the comb holder may be latched to prevent relative sliding movement with respect to the portion of the attachment which is directly but releasably mounted on the clipper head.

While this invention has been herein described in detail in its present preferred form or embodiment, it will be apparent to persons skilled in the art, after understanding the improvements, that various changes and modifications may be made therein without departing from the spirit or scope thereof. I propose inv the appended claims to cover all such changes and modifications.
