' An additional object is that of providing an 5 apparatus which will embody a relatively simple r`construction capable of being manufactured and It is well appreciated by those skilled in the art that numerous attempts have been made to assembled at a comparatively nominal figure. develop a power driven razor.

This blade has embraced a large number of teeth or projections, it the side edges of whichwere sharpened. The guard has similarly included a large number of spaced elements, each having sharpened edges` 20 which cooperated with the edges of the blade projections, so that as the blade was reciprocated within the guard a shearing action would occur.. Various forms of this apparatus have appeared upon the market, and it has been customary to mount the guard and blade assembly upon a head portion coupled to `a handle. The latter has been hollow and has enclosed a motor which, when energized, has served to reciprocate the blade or otherwise suitably move the same with respect to the guard. j - Aside from other objections, one major diñ'ì 30 culty which has been present in an apparatus of this nature has „been that the user, in pressing Áthe guard against the skin, has caused the skin to wrinkle under the guard, as a consequence of which the hair or whiskers have tended to as sume positions parallel to the skin surface. -As a ' With these and other objects in mind, refer ence is had to the attachedsheets of drawings illustrating practical embodiments of the inven tion, and in which: . 15 K Fig. 1 is a plan view of the razor; ` Fig. 2 is a sectional side view_ thereof taken along the lines i-i and in the direction of the arrows >as indicated in Fig. 1; - Fig. 3 is a sectional bottom plan view taken along the lines t--i and in the» direction of _the arrows is viewed in Fig. 2; - Fig. 4 is a side elevation of the head unit;4 Fig. 5 is a sectional -front view taken along the lines 5-‘5 and in the direction of the arrows 25 as indicated in Fig. 2; - ‘ Fig. 6 is a ltransverse sectional view Vof a head and showing a slightly different form of construc tion from that illustrated in the preceding views; . 30 Fig. 'l is a perspective view of the blade embod ied in the' apparatus illustrated in.

Accordingly, the latter will sever , the stubble without it being necessary that the voperator traverse a great number of times the surface which is to becleaned. . .~ 50 ‘ " Still another object is that of providing an ap paratus, the use of which will tend to stimulate ` the skin so Vthat if the latter is in improper con Fig. 11 is a side elevation of a blade as embod ied in the ‘apparatus illustrated in Figs. 8, 9 and 10; 40 ` Figs. 12, 13, and 14 show' alternative forms of head which may be employed; f Fig. 15 isa plan view of still another form of head; i ' Fig. 16 is a transversesectional view taken 45 along the lines lli-_I6 and in the direction of the arrows as indicated in Fig. 15; and Fig. 17 shows a further form of driving mech anism which may be associated with the head.

'I'hese gears are mounted upon housing 24, The casing 24 provides part of‘ the razor head, and is formed with a longitudinal bore 26, which receives a blade body 21. As shown especially carried by shafts 44, rotatablysupported in ex,tensions 46, forming a part of the housing 24. in’Fig. 2, this body is in the form of a tube hav ing an eccentrically disposed bóre and formed with a slot 28 in line with the area where mini _mum material would normally be present.

In these views a mechanism similar to that aforedescribed is presented. However, a pin 46" is associated with the lhousing 24 and rides within a groove 46 50 formed in the blade body 21. Accordingly, the crank 33, in turning, reciprocates within a trans , be appreciated that a minimum of material is to be left adjacent the. outer end of the guard, so that the shearing structure may cooperate to maximum advantage with the hair to be re moved. Additionally, as illustrated, the end of bore 26 may be closed by a cap 36, which latter 55 may be removed for the >purpose of permitting a discharge of any matter accumulated within such bore, and especially within the hollow por tion of the blade body. It is one of the primary objects of the present invention to assure a maximum of coaction be tween the shaving implement and the surface which is to be cleaned. To this end, it is pro posed to tension 'such surface. While-within the purview of the present invention-struc 65 tures may be devised which extend adjacent the shearing zone and which will not be power Ádriven to effect this result, it is preferred that a power driven mechanism be employed. To this end, as shown especially in Figs. 2 and 5, the plate 70 _31 may mount a shaft 31, which extends beyond the housing 24. At this point the shaft supports ' a worm 33. Extending adjacent the worm, and exterior-ly of the housing, .is a shaft 33, which 1 mounts at its lower end a gear 43, to be driven by the worm 33. Adjacent its upper end, 'shaft verse groove 66 formed in such body and causes the latter to merely reciprocate. Now referring to the form of construction; illus 55 trated in Figs. 8 to 1l, it will be observed that there is illustrated a shaving apparatus which is of especial utility for use in removing hair from inaccessible surfaces such as from under the arm-pits and other concave surfaces. To 60 this end, the operating surface of the razor pre sents an outer configuration corresponding to a fragment of a sphere. As illustrated, it includes a guard 5I in the form of a convex body, and -one edge portion of which is preferably shaped to 65 provide a comb portion 62, the teeth edges of which 4are sharpened to present shearing sur faces. 'I'his body may have a central stud 63, which serves to movably mount a blade 66 in spaced relationship to the guard 6I. This blade, 70 as especially shown in Fig. 11, has teeth 66, the side edges of which are sharpened or beveled to cooperate to maximum advantage with the ad jacent surfaces of. the comb projections. The blade may be formed with a central opening 75 3 2,119,248 Vwithin which the bosses 53 project, as well as openings 51 spaced from the central opening andÁ through which fastening elements such as screws ~ 58 may extend. The blade is also-formed with an opening 58 within which `a pin 59 rides. - VThis only a single roller has been employed, it being the intention that the skin shall be stretched between this roller andthe remote edge of theI guard. Thus, the numeral .8l indicates a roller which by means of gears 82 and 83 may be turned ' pin is ecc-entrically mounted upon the end of with respect to the raàor head. In common with a- shaft 69 housed within the body or handle- 6I ofthe guard. The inner end of the shaft is cou pled to a universal joint 62, which may in turn the constructions previously described, the gear ’ 83 may be turned‘by a worm 84 mounted by a _be coupled to a shaft 63 mounted, for example, in anti-friotional bearings 64 and having, if de sired, a clutch part 65, by means of Vwhich it may be coupled to an immediately adjacent motor or to a remote source of power drive. The blade is shaft 85, in turn supporting a worm-wheel 86 10 driven by a worm 81. Now referring tothe apparatus as illustrated in Figs. 16 and 1'1, it will be noted that in-this view the rollers have been dispensed with, al though it will be equally apparent that rollers element is presented which will readily cooperate might be employed if this were desired. In lieu 15 of the vrollers a double guard yand cutting mecha nisrn has been employed,- and these guards may be arranged in tangential planes so as to cooperate to best advantage with the surface to be shaved. In these views, the numeral 88 indicates a drive 20 shaft which serves to rotate a pin 89 through av circular path. This pin rides- in a groove corre to maximum advantage with surfaces which are sponding to the construction presented in Figs. overlain by a plate 66 through which the fasten ing elements 58 extend and which plate serves not alone to protect the shearing edge of the blade but also functions to maintain the blade against accidental displacement. » ‘ ' `It is obvious in operation that, due to the fact that the blade is in effect a spherical section, an 6, '1 and 13 and which forms a part of a blade element 65 or its equivalent 'causes‘the pin 59 to , body 98 disposed within a guard structure 9|. 25 move through a circular path, thus oscillating the , The housing providing this structure is continued blade 55 to exert a shearing effect.

Incident to the stretching action to which the skin will be sub 45 fore described in connection with Figs. 1 to '7. jected i_n having this head pass over it, it is ob However, it will be observed that by the con vious thatthe rollers may be dispensed with, al wheel is driven by a worm 16.

Of coursefunder any circumstances itis proposed to properly encase these gears, al ; though for the sake of simplicitythis has> not been illustrated in the drawings. In the form of apparatus shown in Fig. 13, ' substantially the same construction as illustrated though-as afore brought out-one or more of these elements might be »employed if desired. Referring tothe construction shown in Fig. 17, so itwill be observed that a slightly simpler form of drive has been illustrated than is presented in certain of the preceding views. This drive has been shown uncovered, although it is intended that a protecting casing shall be employed. The 55 drive‘includes a shaft 95 rotatably supported ad- “ in Fig. 12 has been employed.
