Description

. June 14 1927- 1 "J. l-LIHINES mun CLIPPER Filed April 26. 1926 Patented June 14, 1927.
" JAMES H. HINES, OF HOBART, OKLAHOMA.
mm CLIPPER.
Application filed April 26,
This invention relates to hair clippers and its main object is to provide a power 0 erated clipper of simple, durable and eflicient construction.
Another object is to provide means embodied in the clipper for cooling the clipper blades and preventing the hair from working into the clipper.
Another object is to provide means for tightening the clipper blades without unduly increasing friction.
Other objects and advantages of the device will be apparent from the following specification and the accompanying drawmg.
in the drawing Figure 1 is a longitudinal vertical section of the clipper.
Figure 2 is a plan view of the clipper, with the upper half of the housing removed to show the working mechanism.
Figure 3 is a plan view of the clipper, assembled.
Figure 4; is a detail of the blade oscillating eccentric or cam and the associated parts.
In constructing and assembling the elements of my invention, I provide the conventional clipper base 1 having the lower half 3 of a housing 2 secured thereto. Bearing standards 5 and 6 are rigidly secured in the lower half 3 of the said housing 2, and have ball bearings 7 mounted therein. The forward standard 5 is provided with air apertures 8 cut therein near the lower half of the housing. A drive shaft 9 is journalled through the ball bearings 7 and has its forward end reduced as shown at 10. An eccentric or cam 11 is adjustably secured-upon the reduced and extended end 10, by means of a set screw 25, and is adapted to engage and rotate between the prongs 26 of a forked pivot bar 12 mounted upon a pivot stem 13 located between the standard 5 and the cllpper base 1. The forward end of the pivot bar terminates in a finger 14 adapted to engage a recess or socket 18 formed in a movable or oscillating clipper blade 15. The said clipper blade is mounted upon the clipper base 1 by means of apertures 16 cut in the said clipper blade which are engaged by guide pins 17 secured in the clipper base 1. An'askew-set fan blade 19 is secured to the shaft 9 between the standards 5 and 6, and is adapted to drive a current of air through the air apertures 8. The upper end of the over the screw .20
1926. Serial No. 104,772.
said pivot stem 13 is threaded as shown at 20, to permit releasably securing the pivot bar upon the said pivot'13 by means of a nut 21. A pressure plate 22, carrying ball bearings 23 at itstherethrough, and the said ball bearings are ad ustedto nicely bear upon the upper side of the blade 15, while the rear end of the plate has a bearing upon the standard 5. A nut 24 is provided for securing the said pressure plate 22 upon the screw 20 and adforward end, is mounted which passes medlally justing the tension of the ball bearings 23 upon the said clipper blade 15. 'The upper half 4 of the housing 2 is adapted to frictionally engage the standards 5 and 6 for enclosing the working mechanism of the said clipper.
1n operation, the rotation of the shaft '9 by means of any suitable power, such as a flexible shaft connected with a motor, causes the eccentric 11 to reciprocate the pivot bar 12 and thereby reciprocate or oscillate the.
clipper blade 15 thus giving the said clipper blade its cutting motion. In rotating the shaft 9 the fan blade 19 forces air thru the apertures 8 iii-the standard 5 for cooling the said clipper blade as well as for blowing the particles of cut hair therefrom. Through the adjustable mounting of the eccentric 11 upon the end of the shaft 9, the said cam may be readily moved forwardly or back-- wardly within the prongs 26, thereby correspondingly increasing or diminishing the oscillatory travel. of the blade 15.
\Vhile I have herein described a certain specific method of constructing and assem bling the elements of my invention, it is understood same may be varied in minor details, not departing from the spirit of my invention as defined in the appended claim.
I claim:
A transmission unit comprising a rotatable mounted shaft having an eccentric mounted on one end of said shaft, said eccentric being longitudinally adjustable on said shaft, in combination with a bifurcated lever having comparatively long parallel bifurcations in engagement with the operative or camming surface of the eccentric, the bifurcations and shaft being substantially parallel whereby'the throw of the lever may be varied by adjustment of the eccentric upon the shaft. r
In testimony whereof I aflix my signature.
