UNITED STATES HOMER E. DERBY, F APACHE, OKLAHOMA.

CLIPPER.

Application led October 16, 1922.Y Serial No. 594,897.

To all whom` t may concern.'

Be it known that I, Homin E. DERBY, a citizen of the United States, residing at Apache, inthe county of Caddo and State of Oklahoma, have invented new and useful Improvements in Clippers, of which the following is a specification.- Y

An object of the present invention isto produce a power driven hair clipper which.

may be effectively gripped by the operator and operated without muscular fatigue, and one wherein a continuo-us current of air will be forced over the cutting'blades to preventhair clogging the same, as well as 4to add to the comfort of the person operated on.

To the attainment of the foregoing, and other objects which will present themselves as the naturel of the invention is better uni derstood, reference is to be had to the drawings which accompany and form part of this application.

In. the drawings Figure 1 is a side elevation of the iinprovement.

Figure 2 is a top plan view thereof.

Figure 3 is a front view thereof.

Figure 4 is a similar view with the front plate or block removed.

Figure 5 is a sectional view approximately on the line 5-5 of Figure 2.

Figure 6 is a perspective view of the guard.

Fig. 7 is a transverse section of the device on line 7-7 of Fig. 5.

The head block l of the improvement is preferably in the nature of a metal casting, having its body portion round, its bottom extended at an upward angle and notched, as at 2, and its front disposed at a. downward angle, as indicated b y the numeral 3. The head block 1 is provided with any desired number of spaced longitudinally extending apertures 4 that provide outlets for the' air current created by the fan, hereinafter def scribed.

Seated in the notch 2 and secured to the head block by screws 6 is the stationary bar 7 of the clipper. The bar, of course, has its outer edge provided with the usual teeth, and arranged for reciprocation'over the bar 7 is the movable bar or blade 8. The blade 8 is, of course, also provided with teeth which are disposed over the teeth 'of the fixed blade or bar 7 The reciprocatory blade 8 is, at points opposite its center, provided with upstanding lugs 9 respectively.

Arranged over the rounded body portion of the block 1 there is the cylindrical body 10 of the improvement. This body' has its outer `surface provided with longitudinal ribs 11. By thus corrugating the tubular body an effective grip may be had thereon, it being understood that the body serves as the handle portion of the improvement.

The louter end of the body is closed. In the body 1() there is integrally formed a disk 12, the said disk having a central opening 13 which aligns with a similar yopening 14 in the block 1, and passing through and find- On t-he shaft, to the opposite sides of the partition disk 12 there are collars 16 respectively, binding elements 17 passing through the collars and contacting with the shaft whereby the shaft is held against longitudinal movement through the body. The end of the shaft projecting through the head block has a cam extension 18 disposed between the lugs 9 of the reciprocatory blade 8.

Fixed on the shaft 15 between the partition disk 12 and the head block 1 there is a fan 19. Between its ribs 11, opposite the fan 19, the body is provided with an air inlet port 10. The end or closure disk 11 for the body or handle 10 has a central opening 2O therethrough in a. line with the shaft 15. The end of the shaft adjacent the opening is provided with a notch or groove 21, whereby a flexible shaft (not shown) may be passed through and receive a bearing in the opening 20, and be connected to the shaft. The shaft is preferably electrically operated, and it will be apparent that the turning of the shaft not only reciprocates the blade 8, but creates a current of air in the body or han` dle 10, which is forced through the apertures 4 over the blades.

The guard for the improvement comprises a hollow member' whose outer face is arranged at a downward angle, as indicated by the numeral 22, whose rear end is rounded, as at 23 to be arranged over the rounded top of the device. The sides 24 of the guard are directed toward the block and body, being disposed in contacting engagement therewith, while the bottom wall 25 of the guard is apertured, or may be provided with a continuous opening 26 arranged directly over lng a bearing in this opening is a shaft 15.

the blade S. The said rear wall has its rear end portion disposed at a downward angle, the said wall being thickened at this part, as indicated by the numeral 26, and the blade 8 has its rear edge cut at a similar angle, the said angle portion Q7 being in slight contacting engagement with the angle portion 2G. The guard, it will be thus noted, directs the current of air from the fan downwardly through the openings or apertures (S over the blades 8 and 7 so that clogging of the blades by the entrance of hair therebetween will be prevented, while in addition to this, such air currents add to the comfort of the person operated on.

The sides of the guard have their ends pro'- vided with inwardly directed flanges 28 that are received in notches 29 in the sides of the body. Passing through the top portion Q3 of the guard as well as the body 10, and engaging a threaded aperture in the head block 1 is a thumb screw 30. By this means it will be noted that the removable guard is effectively clamped on the device.

It is thought that the foregoing description, when taken in connection with the drawings will fully set forth the construction, operation and advantages of the'improvement as well as the simplicity thereof, so that further detailed description will not be attempted. n

Having described the invention, l claim A hair clipper, a tubular casing, a solid member received in one end of the casing and closing the saine and having its outer n and lower faces beveled towards each other,

a guard carried by the lower beveled face, a reciprocatory cutting blade on the guard, a shaft ournaled in the casing and solid member, and operative connection between the shaft and cutter blade, a shield arranged forwardly of the solid member and being substantially arcuate in cross section and cxtended around the adjacent end of the casing, the shield being substantially semi-cone shaped in vertical section and having its base end overlying the cutter blade and disposed in close proximity thereto, a fan element on the shaft, and the solid element being provided with openings through which air currents arer adapted to pass to be deflected downwardly by the shield and over the cutter blade.

In testimony' whereof I affix my signature.
