. it known as hair clippers, and used for clipping hair, wool, furs, etc, at rapid rates or speed. V w

More specifically stated, my invention contemplates 2. hair clipper operated by power and provided with suction mechanism for removing the material as rapidly as the same is severe.

My invention relates more particularly to the form and arrangement of the various parts, for improving the general 'fiillc pncy of the mechanism as hereinafter set iorth in the specification andfcleirus. 1

Reference is to he made to the ncc'ompuliy ing drawings, forming apart of this spcci float-ion, and in which like reference char-- acters indicate like parts in all of the figures.

Figure 1 is a, fragmentary plan of my device, parts being broken away.

Fig. 2 is a section on the line 2-2 01- Fig. l, looking in the direction of the arrows, and showing the cutting mechanism and parts adjacent thereto.

, Fig. 3 is a fragmentary side elevation of a part of the casing and a gear box mounted 35 thereupon.

Fig. 4 is a fragmentary view of the device, showing it partly in side elevation and partly in a substantially central vertical section.

Fig. 5 is a section on the line 5' 5 of Fig. l looking in the direction of the arrows, and showing the exhaust fan.

Fig. 6 is a detail view, showing a cross section on the line 6--6 of Fig. l.

t, "looking in the direction of the arrow. Fig. 8 is a perspective of the retaining brig, forstoring the material severed.

Fig. 9 is a fragmentary perspective of the cutting mechanism anl the exhaust passage. Y Fig. 1.0 is a perspe, tive of the finger plate forming a part of the cutting mechanism. Fig. 11 is a perspective of the cutter plate. Fig. 12 is a perspective of the rocking lever for actuating the cutter plate.

A handle portion 13, having a cross sec- Fig. 7 is a section on the line 7-7 of Fig.

on indicated in Fig. 6, carricsa hollbw flat portion ll, which has a cross section in di ll fld in Fig. 7 and is provided with a floor 145* and with an upturned or flaring end portion 15. Above the hollow flat p0rtlon 1-4; is a casing plate 16, provided Withgm a foot portion 1o. s red directly to the top of the portion 1%,

Just above-the portion 1% g bevel gear 17, provided with teeth 18 and covered by t ca ng p his bevel cured rigidly upon a short revoluble shaf 1i e1 19. Engaging the bevel gear is e bevel 1 ion 20, which ca ries it Stub shaft .2 7611* tending through the adjacent Wall Of the casing plate 16 and thus journaled th r t0.-

Uetachahly mounted upon the under side of the floor 14 is a finger plate 22, GMT ing a pivot pm 23 extending upwardly rom it and having in this instance the form of a screw. Fastening screWsU24: secure one ,end of the finger .plate to the handle port on 13.-

'l he finger plate 22 is provided with a number of fingers 25 integral with it and haviin r the general f r of a row -j The linger plate carries a P of guide lugs 26 extending upwardly t g slots 26" in a mQvabIccutting plate 2 as indicatcd more particularly i Fig; 2.- Th ting plate 27 carries it number-19f cu g blades 28 integral with it and having the general form of a row of teeth. The cut plate is also provided with a pair of downturned ends 29 which rest upon the finger plate 22, the row of cut-ting blades 28 also resting upon the finger plate. Jouruuled u on the pivot pin 23 is a rocklug lever 30 having the form shown more particularly in Figs. 2 hurl 12.- It has a pivot hole 31 for receiving the pivot pin 23. It also has a head '82, whim ex end .into a recess 32" with which the t g plate 27 is provided, as shown in Fig. 2. The rocking lever 30 is also provided w th downturned bearing members 33, 34, which" to the edge of theifinger plate at a point substantially opposite the hinge 37. Bly rejaws 57, 58. The bag is also provided with movmgthe thumb screw 38, the yo 'e 36 clasps 59 for holding these- 3aws together can be swung upwardly upon the hinge37 as a center, and this facilitates the removal of the finger plate 22.

An ad usting screw 38 extends through the yoke 36 and is encircled by a spiral spring 40. By turning the screw 39 'the finger plate 22 is adjusted bodily in relation to otherparts, andthe degree of pressure between the movable and stationarycutting V members is regulated accordingly.

-Integral with the handle portion 13 is a pocket 40, havin a peripheral flange 41, andsecured to th flange is. a fan-casin I, 42. Extendin through this fan casing is a revoluble sha t 43 carrying. a fan 44and a bevel pinion .45. Engaging this bevel pinion 45 is another 2d-bevel pinion 46. These bevel pinions 45, 46

are located within a gearbox 47. Adjacent this gear box is a bearing 48 and supported and guided by this bearing is a flexible shaft 49 upon which the bevel pinion 47 is rigidly "mounted, so as to turn with the flexible shaft. This'extends. through the gear box 47 and through bearings 50, 51 as well as through the'handle the bevel pinion 20.

i 8o Power is applied to the flexible shaft 49 in anv convenient source, not shown. The

. shaft being causedto rotate, the fan driven through the medium of the bevel pinions 46, 45 and air is drawn through the gppaiatusas indicated by the arrows in The rotation or: the flexible shaft also causes the pinion 20. to turn, and this causes the rotation of the bevel gear 17 and shaft 19. The cam 36 thereupon communicates a rocking movement to the lever 30, This causes the cutting plate 27 to 'slideback and forth across the fin cr plate 22, so thatthe blades 28 are moved 28. The hair or other material. severed by thecutting is sucked into the open or flared end 15 and drawn through the hollow flat portion 14 and. handle portion 13 to the pocket40 whence it passes u wardly into.- the fan casing and is thence may be understood from the arrows shown in Fig. 4. The pocket 40 is held in position by aid of bolts 42 as shown in Fig. 3.

The -fancasing is provided with aneck 66 carrying a pin 53. A bag 54 (see Fig. 8) 1s used'for receiving and temporarily storing the hair or other material severed by the apparatus. The bag 54 'isprovided with a fneclr'55, which fits concentrically upon the necli 52,the neck 55 having a slot 56 for receivin thepin .53 in order to prevent the bag 54 roin turning bodily in relation to other arts. I

To acilitate' removal of the hair or other .16 the bag 54 is provided with purse e pocket by aid of this portion 13, and carries relatively to the fingers. j

( riv'en outyas is to be opened. my device is as fol:

other material to be cut. To facilitate the work, one moves the device as may suit his 30 convenience, for instance passing it over or around apersons head from Wl'llCll hair is to be cut. Thesevcrcd material is drawn.

throu h the handle portion 13 as elsewhere descri ed, and ultimately discharged into 35 the bag 54.. f

p The parts are soformed and positioned that-while tlie deviceis in'use the fan casmg does not obstruct the operators view. The handle portion :18 is tangential to the fan casing, as slibwn in Fig. 1, and is slightly askew relatively to the general direction in which the. fingers 25 and cutting blades 28extend. The parts are thus positioned very .favorably fol enabling the operator to hold the handle portion 13 in his righthand while he can observe accurately every detail of the cutting operation.
