COMB FOR HAIR CLIPPERS Filed Jan. 27, 1949 Patented Dec. 4, 1951 UNITED" PATENT OFFICE y 1 2,577,357 I d COMB'FORfHAIR'CLIPPERS aisaqrasqtai, Highwood..II.l., assignor; by direct. dzvmesne.assignments, of one-half to Adelmo G iorgi Highwood; Application January 2'7, 1949. SeriaINo. 73 030 The present invention relates to an improved arrangement for yieldably mounting or attaching a hair comb to a hair clipper, thereby 'topermit relative tilting movement between the clipper head and the comb for the purpose of -varying the depth of cut made bythe-clipper during each sweep or stroke thereof. The arrangement is such that the hair comb may be quicklymounted on or detached from clippers of either the handoperated orthe mechanically operated type. When in its mounted position the comb hasa yieldable connectionwith the clipper, such-connectionbeing definedby aspring metalstrip attached at-its ends respectively to the clipper head and to the comb. For the purposeof increasing the yieldability of such connection the metal strip is preformed with an S-shaped bend in its central region. This provides approximately straight or flat terminal regions extending in opposite directions which may be removably mounted respectively on the clipper head and the comb.

Oneof the principal objects of this invention is to simplify the construction of a comb attachment-for hair clippers such as contemplated hereand to improve the efficiency and operation of such attachment.

Another'primary object'resides inproviding a yieldable connection between the clipperhead and the comb', such connection being defined by a structurally separate spring metal strip the terminal regionsof-which strip are demountably engaged with suitable guide meanscarriedrespectively by the comb andby one ofthe members-of the clipper head.

Still another object hereof is to-provide a-novel hair comb which is characterized byhavingthereon suitable guide means preferably-molded integrally with. the back thereof, and constructed to 1-6 Claims. (chat-201;) I

The. drawingsrare to be understood as being moreor. less of a diagrammatic character for the purpose of disclosing. typical or preferred embodiments. of the improvements contemplated herein, and-in said drawings the samereference characters identify similar. parts inthedifierent views.

As seen in Fig. 1 the'assembly NJ at the distal portion- .of the hair clipper comprises a fixed toothedqguard H across, which a tooth. cutter plate I2 is rapidly vibrated by suitable actuating mechanism that isusually housed ina holder or casing: The-hair comb M is approximately the same width as the guard H and it is preferably arranged in a plane that is oblique to. the plane of the guard so that said comb inclines towards the-apices of the guard teeth. There is a yieldable connection between the comb and guard and=this connection such that the operator may readily adjust the comb by sliding it forwardly or. rearwardlyto change-therelationship of'the comb to the cutting mechanism. Also, while perform- 3 ing a cutting operation the operator may tilt the clipper up or down or may cant it sidewise, in order to graduate the length of hair remaining on the scalp. It will be understood that during clipping operations, the comb is presented flat against the scalp and the whole assembly is guided by the operator in the direction for making the proper or desired kind of cut or the length thereof. It is therefore apparent that an operator requires but little skill to successfully manipulate the structure in a manner to neatly trim hair in a graduated length upwardly from the lower region of the neck to the pate or crown of the head; as well as around and above the ears and toward the temples of the head. 1 e 7 In its preferred forms, illustrated in detail in Figs. 1 through 5, the yieldable connection bethat the attaching member may be such as shown in Fig.4 which comprises a metal strip 32 formed with a longitudinal depression 33 of U-section and having outwardly extending side flanges 34 that are serrated at 35 in the same manner as in the preferred form shown in Fig. 2. This metal strip 32 is secured to the back of the comb by small rivets or attaching pins 36, and functions as a sliding guide for the comb when the strip is mounted thereon.

In the arrangement shown in Fig. 6 the comb has a narrow plate 31 riveted to it with its channel "'38 facing and covered by the back of the comb.

tween the clipper guard I l and the comb I 5 comprises a structurally separate strip 15 of spring metal. The intermediate or central region is preformed into a pair of oppositely formed or .reverse bends l6 and I! which together define anogee or S-shape formation to increase the yield: ability of the strip and permit the tilting movements of the clipper with respect to the comb as above suggested. The terminal regions [8 and I9 of the metal strip extend in opposite directions from the S-shape formation and they are generally straight or flat to permit sliding thereof while engaging portions of the guard and comb respectively.

For the purpose of securing the above-mentioned sliding relationship an elongate metal mounting plate 23, having an angular channel 2i therein, is suitably secured to the back surface of the guard ll so that the open portion of the channel is next to the guard and provides therewith a pocket-like guide into which the terminal region 18 is adapted to fit. An off-set 22 at the end of terminal l8 engages the end edge of the channel and holds the strip against accidental dislodgement but at the same time permits the terminal l8 to be forcibly withdrawn, through the channel pocket 2! to disassemble the clipper from the guide. guard plate, or as shown in Fig. '7, open slots 23 are made in this mounting plate for inserting the latter around the shanks of longer screws :24 which replace the usual screws for attaching the guard to the cutter head. After being positioned in place retainer nuts 25 are tightened onto screws2 l to hold the plates in assembly.

In its preferred form as shown in Fig. 3 the second terminal 19 of the spring strip is preformed with downturned inwardly extending flanges 26 of L-section which extend along its longitudinal edges. Between the bend IB'and the adjacent ends of these flanges there is a transverse bend or rib 21 which defines one portion of a latch arrangement. The comb M has an elongate guide 28 the sides of which are undercut as at 29 to provide oppositely extending wings that are slidably embraced by the L-shaped flanges 26 of the terminal region I9 of the spring strip.

The outer or upper face of guide 28 has transverse serrations 3! one of which is engaged by the rib or bend 2'! on the spring strip 15 to latch the comb in different positions within the limits of its sliding movement while being supported on the strip by the holder flanges 26. It will be understood that the comb structure above described may be readily molded from a suitable plastic composition with the attaching member 28 integral with its back portion. It is contemplated Plate may be.welded to the- .In this simplified arrangement the terminal region IQ of strip I5 has a bowed shape as at 39 to frictionally contact at least the top and bottom walls of thepocket formed by the channel piece laying against the surface of the comb. The extreme end of the spring strip has an offset deformation or lip 48 to project outside said pocket to retain the comb against accidental dislodgement but at the same time permitting the comb to be adjustably moved or slid along the terminal region IS in the same manner as in the other forms shown. I 7

An alternative arrangement for mounting the spring strip [5 on the clipper head is shown in Fig. 8 wherein the guard II is formed with a socket 4| extending inwardly from the rear edge of said guard and disposed somewhat oblique to the faces of the guard. Only slight clearance is presented between the socket walls and the 'terminal region l8 of the spring strip to prevent any relative sidewise or longitudinal movement of the comb mounting devices and the clipper.

It is contemplated that the straight end region of the spring strip I5, which assembles with the hair comb M, be wider than the remaining portion of the strip as shown at l9a in Fig. 9. The comb has a guide 42 of channel cross-section secured to its back, said guide having L-shape side edges the lateral flanges 43 of which extend towards each other to define a longitudinal slot or throat 44, to receive the arcuately bent portion. The up- 16 of the spring connecting strip l5. standing flanges 45 of the L-shape'edges of the guide are spacedv apart a distance to provide a minimum of clearance for the wide head Illa. of

the strip, and the body portion of the guide is the three regions of frictional contact between the head, um and the guide 42. The guide is secured in place by tabs r ears 47,, at its opposite ends which are pinned as at 48 to the comb. For preventing the comb l4 being movedtoo far rearwardly, the forward tab or ear, which is bent down to lie between the roots of the comb teeth, is formed withan abutment 49 which acts as a stop when contacted by the end edge of the wider head portion Illa. of the spring strip l5.

It is apparent from the foregoing that while cutting hair the comb will glide fiat against the scalp and the clipper may be tilted as desired to graduate the cut, or the clipper may be canted sidewise as indicated by the arrows and the dotted lines in Fig. 5 to facilitate removing hair around and above the ears. As a result of thisgarrangement considerable time is saved and a large amount'of labor is eliminated when cutting hair indifierent-styles; and it hasbeen found i tual experience that only: a few minutes areree quired to complete a hair cuttingoperation. The manner of manipulating the device-is so simple that an inexperienced person is able to cut hair efficiently and satisfactorilywitheither. an automatically operated or a hand operatedhair clipper onv which the present hair comb arrangement is mounted by means of structures-such as disclosed herein. v I

While the improvements-s have been described in detail in the typical-or preferred embodiment, it will be apparentto persons skilled in the art. after understanding the construction and operation of this assembly, that changes and modifications may be made therein without departing from the spirit or scope thereof.
