KING HAIR CLIPPER Filed Aug. 10, 1940 2 Sheets-Sheet 2 I Inventor MIA 7" L'. KI)? 9 By I Attorney v Patented July 15, 1941 UNITED STATES PATENT OFFICE Barry L. King, International run, Minn. bllpuclflon AIM 10, 194., Serial Nil-@524 2 Chill. (01- 30-133) The present invention relates to new and useful improvements in hair clippers and has for its primary object to provide, in a manner as hereinafter set forth. a device of this character comprising a stationary cutter of novel form whereby the correct inclination or bevel may be expeditiously made when trimming the hair.

Another important object of the invention is to provide a clipper of the aforementioned character embodying unique means for positioning the hair in the cutters.

, Still another important object of the invention is to provide a clipper of the character described comprising means for removing the cut hair.

Other objects of the invention are to provide a hair clipper which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact. light in weight and which may be manufactured at low cost. I

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding. parts throughout the several views, and wherein:

Figure 1 is a perspective view of a hair clipper constructed in accordance with the present invention, showing the device in use.

- Figure 2 is a view principally in vertical longitudinal section through the clipper.

Figure 3 is a plan view of the removable head, looking at said head substantially from the line 3-2 of Fig. 2.

Figure 4 is a sectional view, taken substantially on theline 44ofFig. 2.

Figure 5 is a view in front elevation of the cutters.

Figure 6 is a cross sectional view through the brushes, taken substantially on the line 6-8 of Fi 2.

Figure '7 is a sectional view, taken substantially on the line 1-1 of Fig. 8.

Figure 8 is a detail view in elevation of one of the brushes.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a hollow body I of suitable material, said body housing a conventional electric motor (not shown). The

body I also constitutes the handle of the device.

Mounted beneath the lower front portion of the body I is a swinging tongue 2 which is connected to said body by a spring hinge 3. Removably mounted on the tongue 2 is a cutter mounting the head 4 on the body I.

head which is designated generally by the reference numeral 4.

The head 4 includes a stationary cutter I which, as best seen in Fig. 5 of the drawings, is substantially triangular in cross section.

Mounted on the rear portion of the stationary cutter I is a metallic loop 8' which slidably receives the tongue 2 for hingedly and removably The head I further includes a transversely reciprocating cutter 6 which is mounted on the stationary cutter I. The. reciprocating cutter 6 is slidably and removably secured on the stationary cutter I through the medium of a substantially U-.

shaped spring I having its end portions secured to said cutter I, as at I. A transverse slot I in the reciprocating cutter l accommodates a rib or the like II on the retaining spring I.

The reference numeral I I designates a shaft in the body I which is driven by the aforementioned electric motor. A worm gear I2 on the forward end of the shaft I'I drives a gear II in the forward portion of the body I. Mounted for oscillation in the forward portion of the body I isa suction fan. At its forward end, the suction conduit I'l terminates in a flared intake nozzle :8 located above and closely adjacent the cutting teeth of the members 5 and 6 Formed on the upper portion of the nozzle It and projecting forwardly therefrom is a plate I9. Formed integrally with the forwardly projecting portion of the plate I9 is a transverse bearing 20. A shaft 2| is journaled in the bearing 20, the end portions of said shaft being threaded and projecting beyond the ends of said bearing. 'Mounted on the end portions of the shaft 2| for rotation therewith are substantially conical brushes 22. The inner end portions of the brushes have formed therein sockets 23 which receive the end portions of the bearing 2!. The brushes 22 are located closely adjacent the front of the stationary cutter 5.-

Fixed on the inner end of one of the brushes 22 is a beveled gear 24. The gear 24 is driven by a beveled gear 25 on the forwarden'd portion of a shaft 2 which extends longitudinally into the. upper portion of the suction conduit l'l through the top wall of the nozzle I8. Extending from the conduit Il into the body I is a shaft 21. Beveled gears 28 drive the shaft 21 from the shaft H. Beveled gears 29 connect the shaft 26 to the shaft 21 for actuation thereby. The construction and arrangement is such that the brushes 22 are driven at comparatively low speed from the electric motor in the body I, which motor also drives the reciprocating cutter 6.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, the clipper is started at the back of the neck and brought up over the ear toward the temple for trimming the hair on one side, as suggested in Fig. 1 of the drawings. The clipper is then turned and the other side of the head is trimmed in a similar manner. The shape of the stationary cutter 5 is such as to cut the hair at the desired bevel or inclination. The

brushes 22 sweep the hair into the teeth of the 20 cutters 5 and i where it is straightened up by the suction in the conduit ll, said conduit also carrying 011' the cut hair.

It is believed the many advantages of a hair clipper constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to provided they fall within the scope of the invention as claimed.

What is claimed is:

1. A hair clipper comprising a body, coactlng cutters mounted on said body, a brush rotatably mounted on the body, for sweeping the hair into the cutters, and means for actuating the brush and one of the cutters.

2. A hair clipper comprising, in combination, a body, cutting means on the body, a brush for engaging the hair with said cutting means. suction means for straightening the hair in the cutting means, and means for actuating said cutting means and said brush.
