HAIR CLIPPERS Filed Aug. 27, 1929 Patented June 17,1930 1 cairn stares SAM FRIEDMAN, or ATLANTA, enoeerA HAIR CLIPPERS This invention relates to improvements in hair clippers.

The object of the invention is to provide convenient means for gauging the cutof the hair so that a barber may, by manipulating the clippers, taper the hair without the use of the customary scissors.

A further object oi": the invention is to provide a new and novel form of gauge and means for operating the same.

A. further object oi the invention is to provid improved means for attaching and detaching the gauge to the clippers.

The invention also comprehends improve merits in the details of construction and arrangement of parts which will be hereinafter described and pointed out in the claims.

In the drawings Fig. 1 is a plan view showing the application of the invention to a pair of hair clip pers. Fig. 2 1s a side elevation of the same. F 1g. 3 18 a central vertical section on an enlarged scale, the bottom of the clippers being shown in dotted lines.

cally-operated clippers as hand-operated clippers. I 2 indicates a comb, to the rear of whichis fastened a casting 3, from which extends a stationary handle 4. Pivoted at 5 to the casting is a movable handle 6, having a forwardly and downwardly projecting lug 7,

which engages in a recess 8, formed in the upper cutter blade 9, which reciprocates over he comb 2. Extending from the movable handle in rear of its pivotal mounting is a lug 7 which operates in the open end of a bore formed in the casting 3. W'ithin the bore is a spring 13 which bears at one end against the lug 7, and at its other end against a screw 8 threaded in the outer end of the bore. The screw 8 is formed with a central threaded opening 9, which receives a screw 10 having a cam 11.

Application filed. August 27, 1929.1 serial in. 388,82

- On the bottom of the comb isfixed aplate 12 provided with pintles-13; 1 1 indicates a gauge formed'on assent end with teeth 15 and on its sides with flangeslti, one of the latter having anopening 17 for the reception of one of the pintles 13. i

Mounted between'guides'lt) in. the bottom of the gaugeis aslide 20, provided on its inner end witha lip 21 and on its outer end with atlange 22, the latter having an opening 23 which receives one of'thepintles 13. The slide has aylilnited movement in the guides, it being urged inwardly to draw the flange 23 towardthe pintle 18 by a spi'i11g'2'45,one end of which engagesthe lip Eland the otherend being fastened to the gauge, as shown. Extending upwardly from one oithe flanges 16 is a cam lever 25, the upper endot' which lies close to the screw 10. its stated, the screw 10 is provided with a camdlfadapted to engage the cam lever 25totilt the gauge on its pintles to regulate the length of the out. A fiatspring 27 is secured to the gauge 14 and its upper free end engages the underside ofthe plate 12 to normallyhold the toothed 1 end of the gauge up against the teeth of the comb. v

In operation, to apply the gauge to the cl1ppers,'the flange 22 is pulled outwardly against the tension of the spring 24, andthe gauge is forced up against the bottom of the clippers with the pintles 13 in alignment withtheopenings 1723. Then pressure on the slide 20 is released and the pintles take bearings in. the openings, thefspringholding the gauge in position. Assume the parts I arein the position shown-in 2 the cut of the clippers will of course be close, or in other words,short. If, however, a longer cut 7 be desired, the screw 10 is turned and the cam 11, which is adjacent the cam lever 25, contacts with the-latter and tilts the gauge so as to move the" teeth thereof further away trom'the comb. Obviously, when the parts are in the position shown in Fig. 2, by exerting pressureon the rear or heel end of the gauge, the teeth can be held away from the comb, and by gauging the pressure, the barber can readily taper the cut When the screw 10 is turned to engage the, ice

cam 11 with the cam lever 25, the gauge is of course tilted on the pintles against the tension of thespring 27, and of course, when pressure of the cam on the cam lever is removed, the spring urges the teeth 15 toward the comb. 7

To remove the gauge from the clippers, it is only necessary to force the flange 22 outwardly against the tension of the spring 24, m whereupon the pintles can be disengaged from their bearlngs and the gauge dlsconnected.

What I claim is:

1. In combination, hair clippers having a comb and pintles, a gauge comprising teeth tocooperate with the teeth of the comb, bearings on the gauge to receive the pintles, a cam lever extending upwardly from the gauge, a cam carried by the clippers and mounted at right angle to the cam lever in rear of the pint-les to cooperate with said cam lever to tilt the gauge, and a spring between the gauge and clippers to resist the movement of the cam. I

25 2. In combination, hair clippers having a comb and pint-les, a gauge comprising teeth to cooperate with the teeth of the comb, bearin 's on the gauge to receive therpintles, a

cam lever extending upwardly from the 3 gauge, a screw carried by the clippers in rear of the pintles and at right angle to the cam lever, a cam on the screw to cooperate with. the cam lever to tilt the gauge, and a I spring between the gauge and the clippers to resist the movement of the cam.

3. In combination, hair clippers having a comb and pintles, a gauge having an opening in one side, a spring actuated slide mounted on the gauge and having a flange with an 40 opening in alignment with the opening in the gauge, the pintles being. supported in the openings, a spring interposed between the gauge and the clippers to normally tilt the forward end of the gauge in contact with the comb, a cam lever on the gauge, and a rotary cam on the clippers to engage the cam lever to tilt the gauge in opposition to the spring.

4. In combination, hair clippers having a comb and pintles, a gauge formed on one side with an opening, a cam lever extending from the gauge, guides in the gauge, a slide mounted in the guides, said slide having a flange formed with an opening in alignment with the opening in the gauge, a spring mounted between the slide and the gauge to normally force the slide inwardly, the pin tles fitting in the openings, a screw carried by the clippers, said screw having a cam to engage the cam lever to tilt the gauge.

In testimony whereof I a'liiX my signature.
