To all whom it may concern:

Be it known that I, CLYDE O. CONNOR, a citizen of the United States, and a resident of Wichita, in the county of Sedgwiek and State of Kansas, have. invented certain new and useful Improvements in Hair-Clipper Blades, of which the following is a description, referring to the drawings which accompany this specification. v

The invention relates to blades for hair clipping devices, preferably power driven, and as employed by barbers and others; and refers particularly to novel features further explained.

In the drawings, Fig. 1 is a side view of the clipper head with my improvedblades in combination therewith. Fig. 2 is an enlarged detail plan view of the top of the upper blade seen in Fig. 1. Fig. 3 is a plan view showing the bottom of the lower blade seen in Fig. 1. Fig. 4 is a plan view of the top of the lower blade, seen in Fig. 3. Fig. 5 is a sectional view as taken along the line V-V, Fig. l.

Similar numerals of reference indicate corresponding parts throughout all the figures of the drawings.

Referring to the drawings, 6 is the upper blade, slidably supported and operable in the customary manner upon a lower blade 7 in the hair clipping device seen in Fig. 1-. The teeth 8 of the blade 6 are made longer than in ordinary practice for upper clipper blade construction and have corrugated or bearded edges 9, 9 for a portion of the distance inwardly whence the adjacent edges of adjacent teeth terminate in a tapering groove asseen in Fig. 2. The teeth 10 of the lower blade 7 may be fabricated as illus trated in Fig. 4: conforming to the type of blades as usually employed, or they may also be corrugated or bearded in a manner similar to the edges 9 depending upon the desires of the manufacturer thereof.

In Fig 5, the base of the lower blade 7 is The blade 7 is hollowed out at 13 to secure IR-CLJIPPER BLADE.

ranged within the transverse slots 15. 15 of the upper blade 6 in the assembly Fig. 1, thereby furnishing a guide for the upper blade 6 as it slides on the lower blade 7 in operative practice.

Screw holes 16, 16 through the blade 7 enable the said blade to be secured by screws to the head of the clipper.

Corrugating or bearding the teeth as at 9 produces teeth that are to a considerable extent self sharpening under hair cutting operations. and owing to the length of the teeth and to the corrugations, a blade is produced that can be run at a high rate of speed in a power driven machine without choking. thereby producing a clipper that will work at a much faster speed than is possible with hair clippers ordinarily employed.

The curved contour of the lower blade enables the barber to rock the device to conform to the curve of the head during hair cutting operations and to also cut higher on the head than is customary with the ordinary flat bottomed hair clipper. By this rock-able movement, the barber can do a much smoother job of blending the shorter clipped hair into the longer or shingled hair without going over the work several times.

Such modifications may be employed as lie within the scope of the appended claim. Having fully described my invention what I now claim as new and desire to secure by Letters Patent is:

In combination in a. hair cutting device, a lower blade having bearded cutting teeth and an upper blade slidably mounted and controlled thereupon; said lower blade having its base portion convexly curved in two directions, namely from front to back and from side to side; the upper portion of said bladehaving acentral recess therein extending towards the convexly curved base and posts rigid with said base extending through said recessed portion towards the upper blade element.
