GAUGING ATT CHMENT ron Barn oLIrrERs Application filedNovember 26, 1 926. Seri1No. 150,745.

, This invention relates to improvementsin gauging attachments for hair clippers, and more particularly to a'device to be used in conjunction with hair clippers as an aid in 5 cutting hair to the desired length and with uniform graduation over various parts of the head; l

i I .The object of the' invention is to provide a means whereby the useof clippers may be extended to euthairover those portions of the head which'ordinarily require the use of scissorsdue to. the inability of the operator,to guide the clippers at the proper distance from ,the scalp. except where the hair 7 is to be. closely cropped or cut veryfishort.

Moreover, it is difiicult even. for the expert operator to obtain uniform graduation in the length of the hair to be cut or trimmed, and especially to avoid the visible line-which '20 marks the division between that portion of the scalp which has been clipped and that portion 1 which has been trimmed with scissors, I

A preferred embodiment of the invention is disclosed in the accompanying drawings,

inwhich' J- Figure 1 is a perspective view of a hair clipper with the gauging attachment applied'thereto.

Figure 2 isa perspective view of the gauging attachmentremoved from the clippers. Figure 3 is a view in cross-section taken on line 33 of Figure 2. .7 c Figure 4 is' an enlarged detail view in 86 section taken on line L4-of Figure 3.

. Figure isa viewin sideelevation showing the relative position of the bottom plate of the clipperand the/gauge bar. T I Figure 6 is a View similar to Figure ,5 40 showing the gauge bar in depressedposition.

For the purpose of illustration, the attachment is applied to a poweror electrically operated hair clipper A, although it maybe used equally well with a hand clipper, the cutting action of both being substantially the same, In general, hair clippers whether hand OY'POWGI operated, comprise a. pair of fixed and movable cutting plates 1 and 2 having complementary rows of cutting .teeth along their} forward edges. The fixed plate 1 is on thebottomand slides incontact with the scalp, as the movable plate 2 travels crosswise of the fixed plate 'narily attempted. v

with a reciprocating.movement, cutting the hair asitiis fed between the teeth in the forward movementof the clippers.

As fthus constructed, hair clippers are result can only be used on relatively small parts of the scalp, leaving the major portion of the cutting to be done with sclssors.

It is possible to adaptclippers to the cutting or trimming of longer lengths of hair,

clippers and advancing the two together to space the clippers from the scalp. This expedient, however, requires considerable skill on the part of the operator, in orderto obtain satisfactory results and therefore is not ordi In the present device, a portion which functions as acomb is attached directly to the bottom plate of the clipper and remains in a fixed plane. Located behind the comb is an adjustable bar which is shiftable to-' ward and from the bottom of the clipper so teeth and'the surface of the scalp.

by placing a comb orrthe finger under the Referring now to' the construction of the attachment, it consists of a relatively thin metal plate 3 which bearsfiatwise against the bottom surface of the fixed plate 1 of the clipper, and is provided along its forward edge with a row of teeth 4 forming a section of acomh offset ataslight: angle A to the plate 3 to extend parallel to the plane of the beveled edge 1 along the forward edge of the bottom plate 11 (Figure 3).

The plate 3- covers only the. forward portion of the bottom plate; and is removably attached thereto by a spring: clip 5-riveted tothe combplate 3 and having hooked ends 5; 5

which engage the side edges of the bottom plate l of the clipper. Beyond the comb teeth and at each end ofthe plate 3, are for 'wardly extending prongs 6, 6 considerably .arefitted to hold the attachment in place and the comb teeth iii-proper position with respect to the cutting teeth. Alongthe sides voi thev comb plate are upstanding walls 8, 8

80 as to gauge distance. .betweenithe, cutting I fixed cutting teeth of the bottom plate 1, 7

that is, with the same spacing between them so that each comb tooth registers exactly with one of thefixed cutting teeth. Moreover, the comb teeth are preferably triangu lar in cross-section having relatively flat faces on their under sides and tapering to a beveledor substantial knife edge which face toward the beveled edges of the corresponding fixed cutting teeth of the bottom plate of the clippers. The comb teeth, moreover, are tapered from base to tip and are of greater length than the cutting teeth so that they project a quarter of an inch or more beyond the cutting teeth with the base of the comb section disposed back of the base line of the cutting teeth. This formation of the comb teeth, their spacing and registration with the cutting-teeth, tends to promote a' more uniform and smooth cutting action, as it properly divides the hair into small quantities and guides it between the cutting teeth as the clipper is advanced.

Immediately below the plate 3 is an adjustable gauge bar 9 extending transversely of the plate and rearwardly of the comb teeth 4. This bar is mounted for movement toward and from the plate 3, the following means being used for supporting and adjusting the bar to various positions. At the ends of the bar are

arms

10, 10 extending forwardly exterior of the side plates 8, 8, the ends of the arms being pivotally connected to said plates as at 10*. At one side of the device is an adjusting member consisting of a screw 12 pivotally connected at its lower end with the adjacent arm by means of a pin and slot connection as at 13. The screw 12 extends at right angles to the arm and upwardly into a casing 14. the inner wall of whichis adjacent side wall 8, there being a corresponding wall l5 spaced from said side wall within a marginal flange 15 to enclose the top and sides of the casing thus formed. Carried by the screw 12 is a thumb wheel 16, having its periphery projecting through slots 17 formed in the opposite side walls 8 and 15 of the casing 14. Thus by turning the Wheel in either direction, the screw is moved endwise to elevate or depress the gauge bar to obtain the desired space between the bar and the bottom surface of the plate.

The gauge bar 9 is preferablyfiat on its underside and has a width of fromvonefourth to three-eighths of an inch, thus affording sufficient bearing surface to enable the operator to guide the clippers over the scalp Without varying the inclination of the comb and cutting teeth to any appreciable extent. By preference, the gauge bar is arranged so that in fully depressed position (Figure 6) it lies against the plate 8, and flush with the under face of the comb section 4.

As already suggested, the purpose of the gauging attachment is to enable the operator to regulate and thus control the length to which the hair is to be out throughout different portions of the head. For example, When cutting amans hair. it is customaryto clip the hair rather close to the scalp at the back and sides of the neck, and over the ears, gradually increasing the length toward the top or crown of the head.

In the absence of'the attachment, the operator finds it difficult to manipulate the clippers so as to obtain uniform and satisfactory results, without afterwards going over the clipped areas with scissors, this being particularly true where the portions of the head out with the clippers merge with the portion which is merely trimmed with scissors. With the gauging attachment applied to the clippers, the operator can readily adjust the gauge bar to obtain the proper spacing of the cutting teeth from the scalp and thus obtain the desired length of hair. Manifestly, the proper manipulation of the clippers with the gauging attachment requires the exercise of some degree of skill on the part of the operator, although once familiar with its operation. is enabled to cut hair with greater ease, neatness and despatch than is otherwise possible.

- Having set forth a preferred embodiment of our invention, we claim:
