Application November 13, 1952, Serial No. 320,280

15 Claims. (Cl. 30-201) This invention relates to apparatus for clipping hair,

i and particularly to the well known type in which a pair of slotted blades are moved relatively to each other .in a direction to cause the clipping to occur between the edges of the opposed slots.

Such blades are usually quite wide, of the order of one or two inches, to clip the hair along a relatively wide strip. It has been common, in the past, to provide an adjustable comb to determine how closely the hair is to be cut. By this means, a uniform length of hair is left along the path of the clipper.

In some instances, such as near the temples and behind the cars, it is highly desirable that the hair be of minimum length at the hair line, and have a gradually increasing length as the top of the head is approached. These results have usually been effected by proper skilled manipulation of shears or scissors.

It is one of the objects of this invention to make it possible to obtain these eflects in a simple manner, without requiring other than ordinary skill. More particularly, the invention contemplates the provision of an adjustable attachment for a hair clipper to obtain these results.

It is another object of this invention to provide an attachment for this purpose which is adjustable to vary the relative lengths of the cut hair at opposite edges of the blades. Thus, in some instances, the difference in the length of the hair left in the path of the clippers at one side of the path and the other may be readily predetermined, as well as the absolute length of the hair at one of the sides.

It is still another object of this invention to make it possible to clip the hair more closely than heretofore with the usual type of hair clipper.

This invention possesses many other advantages, and has other objects which may be made more clearly apparent from a consideration of one embodiment of the invention. For this purpose there is shown a form in the drawings accompanying and forming part of the present specification. The form will now be described in detail, illustrating the general principles of the invention; but it is to be understood that this detailed description is not to be taken in a limiting sense, since the scope of this invention is best defined by the appended claims.

Referring to the drawings:

Figure 1 is a side elevation of an attachment, including an adjustable comb plate, mounted upon a clipper, and incorporating the invention, the comb plate being cut at an angle with respect to the lower cutting blade;

Fig. 2 is a sectional view, taken along a plane corresponding to line 22 of Fig. 1;

Fig. 3 is a view taken from a plane corresponding to line 33 of Fig. 1; and

Fig. 4 is a fragmentary side view, similar to Fig. 1, showing another adjusted position of the comb plate, and still other positions being indicated in phantom lines.

In the present instance, an electrically driven clipper 1 is shown, having a stationary lower blade 2 and a vibratory upper blade 3. The vibrations are in a direction parallel to the leading edges of the blades. These blades are provided with cooperating slots 4 and 5 (Fig. 3) between which hair to be cut protrudes, and which is cut as the clipper is operated. Since this action is well known, further description is considered unnecessary.

The lower blade 2 is appropriately attached to the lower portion of the clipper 1, as, for example, by the aid of the screws 6.

By the superimposed position of the

blades

2 and 3 and a vibratory movement in a direction parallel to the front edge 7 of the stationary blade 2, the desired cutting action is produced.

The front edge 7 is, in this instance, made relatively narrow, and the blade 2 has a lower surface 8 (Fig. 4) which slopes with respect to the upper cutting surface 9. This lower surface converges with the upper surface to produce the narrow edge 7. The thickness of the blade 2 therefore increases gradually toward the rear of the blade. In this way, a very close clipping action can be produced.

A comb plate 10 of fiat sheet metal, or other appropriate material, is provided to cooperate with the

blades

2 and 3. This comb plate is provided with a series of deep slots 11 to form the comb construction. The forward edge 12 of this comb plate, as described hereinafter, may be adjusted forwardly or rearwardly in order to provide an adjustable guard.

The manner of mounting the comb plate 10 is such that it may be slanted to approach one longitudinal edge of the blade 2, as well as to be spaced considerably from the other edge. This is indicated in Fig. 3.

In this figure, the right-hand portion of the plate 19 approaches more closely to the right-hand edges of the

blades

2 and 3 than to the left-hand edges.

In this way, the comb plate 10 can be used to cut a path through the hair in which the hair is left longer along one edge of the path (the left-hand edge in this in stance) than along the other on the opposite edge. Accordingly, a gradually increasing length of hair is left. This is useful, for example, in cutting hair back of the ears, causing hair to be closely clipped immediately behind the ears while, at the same time, the places farther away from the base of the car are left substantially and progressively longer.

The angularity of the comb plate 10 is made adjustable. This is effected by the aid of the supporting structure of the comb plate 10, which will now be described.

The opposite edges of the comb plate 10 are, in this instance, received in slots 13 and 14 (Fig. 2) disposed in the

clamp members

15 and 16, respectively. These clamp members are urged to clamping position by the aid of a bolt 17. This bolt 17 has a non-circular portion 18 fitting a corresponding non-circular aperture in the clamp member 15. It also passes through the spaced depending cars 19 formed integrally with a bracket 20. interposed between the ears 19 and around bolt 17, is a spacer sleeve 21. A washer 22 is disposed on the bolt 17 and on the outer surface of the member 16. A thumb nut 23, engaging the right-hand threaded end or" the bolt 17, is used for urging the parts together so as to hold the edges of the plate 10 in firm adjusted position.

in this way, the plate 10 can be angularly adjusted about the axis of the bolt 17 when the nut 23 is loosened. At the same time, the position of the forward edge of the comb plate 10, with respect to the

blades

2 and 3, may also be adjusted as indicated by the phantom lines in Fig. 4. This is eifected by appropriate sliding of the plate 10 with respect to the grooves 13 and 14 while the nut 23 is loosened.

In order to provide the angular adjustment of the plate with respect to the longitudinal edges of the

plates

2 and 3, the bracket 20 is pivotally mounted with respect to the clipper 1. For this purpose, the bracket 20 is pro vided with an ear 24. This ear is apertured for the reception of a screw 25which also passes through an ear 26 of a support 27. This support 27 is firmly attached to the lower surface of the blade 2 by the screws 6. The screw 25 is provided with a knurled thumb nut 29 for loosening and tightening bracket 20 with respect to the support 27. By the aid of this screw 25, the angular position of the bracket on an axis corresponding to the axis of the screw 25 can thus be effected. The axis of the screw 25 is in a direction substantially perpendicular to the forward edge 7 of the blade 2. Furthermore, graduation marks 28 are provided on the car 26 to indicate the degree of angularity of the plate 10.

The position of the plate 10 in Figs. 1, 2, and 3 is shown as at an oblique angle about the axis 25 to bring the comb plate 18 to the position indicated in Fig. 3. The comb plate is also adjustable about the axis of bolt 17, so that the longitudinal edges of plate It) may be made oblique to any desired degree with respect to the longitudinal edges of

blades

2 and 3.

In Fig. 4, the plate 10 is shown in intermediate position, lying closely to the tapered surface 8 of the blade 2. The adjustment of the plate 10 in a direction forward or rearward, with respect to the edge 7, is etfected by adjusting its position in the grooves 13 and 14. The angular position about the axis of the bolt 17 is similarly adjustable by the aid of the bolt 17.
