Application @ctober 22, i937, Serial No. 170,442 3_ Claims. (Cl. lib-_43) This invention relates to electric dry shavers and more particularly it relates to an electric dry shaver which is shaped like the ordinary safety razor and which can be operated in the di same manner as the ordinary safety razor but _ Fig. 3 is an enlarged perspective view'of the same embodiment with both the stationary and movable plates removed and showing one of the spring guides. Fig. 4 is an enlarged front elevation of the shaver shown in Figs. l to 3. without the use of soap or the like. Fig. 5 is an enlarged side elevation. ~Like a number of electric shavers now on the Fig. 6 is a toplplanview also enlarged. market, the shaver according to the present . Fig. '7 is an enlarged detail view of one man invention works on the clipper principle having as it does a stationary clipper plate provided with teeth and a movable clipper plate also having teeth and adapted to reciprocate with respect to stationary plate. `When the plates is which are disposed like the blade of a safety razor are drawn across the face whiskers will be directed between the teeth and will be sheared oiî. “ Practically all of the manufacturers of elec tric dry shavers warn their customers not to 'be discouraged with the ?lrst results of use since it frequently takes several weeks and sometimes months before the new strokes and manipula tions necessary can be mastered. With the- pres ent invention no practice is necessary since the 25 device is operated with the same strokes and manipulations as are used with the ordinary safety razor. The present invention is further unlike the electric Shavers now on the market in that the 30 stationary and movable clipper plates are dis posed so as to ‘be in full view at all times so that the operator can see at all times how the razor shaves with each stroke. - l It should already be manifest that one ob 35 ject of the present invention is the provision o-f an electric dry shaver which can be operated in the same manner as the usual safety razor but without the need for soap or the like'. An ner of connecting the actuator to the moving l@ plate, and ` ` Fig. 8 is an enlarged side elevation of another embodiment utilizing .movable and stationary clipper plates which are slightly curved in cross section. . « j 15 'I'he electric dry shaver illustrated inthe draw ings has a handle 2 which may be of hard rub ber, “bakelite” or any suitable insulation mate rial. The handle preferably should- becompar atively small and narrow so as to 4simulate as 20 closely .as possible the size and shape of the handle of the ordinary safety razor. The han dle houses a small electric motor (not shown) which may be of the type used in dry Shavers and which is connected by suitable -mechanism 25 tc impart a limited reciprocatory movement -to an actuator d which extends upwardly from' a rectangular well in the upper end of the han- dle 2. . Formed as to ñt in the well is a supporting 30 member 6 of metal or the like. The member '6' may be die-cast or even stamped and, as shown, has channelled end portions 8 (see Figs. 1 and 5 for example), and topv flange portions I ñ which extend over the -top `surfaces of the .35 handle 2 on each side of the rectangular well.’ The supporting member has a central opening for the actuator 4. The reference numerals I2, I 2’ indicate' sup other object which is apparent is the provision - porting posts of metal or other suitable material. 40 40 of an electric dry shaver yso _designed that the operator can see how the razor shaves' with each stroke. ‘ Another'object of the invention is to provide an electric dry shaver in which the moving clip 45 per plate is not covered and is so arranged as to be easily replaced. ` Still a further object is to provide a shaver in which the moving plate is narrower than the stationary plate and is disposed above the sta 50 tionary plate. s Other objects will be apparentfrom the fol lowing description'and accompanying drawings. In the drawings:- ‘ Fig. l is an enlarged perspective view of one 55 embodiment of the invention showing only the upper portion of the shaver to which the inven tion relates. Fig. 2 is a similar view with the movable clip per plate elevated to show the manner in which 60 the stationary plate is secured. The bases of these supporting posts l2, I2' are preferably square in cross section and they are snugly disposed in the channelled end portions 8 of the supporting member 6 to which they `are secured by suitable means such as by the screws y. I4 and I6. _ The outer sides of the supporting posts I2,. I2' are beveled inwardly towards their upper ends to permit an inward swinging motion of spring members generally indicated by the reference 50 numeral I8. These may be secured nearer the base of the supporting posts I2, I2’ by the~ . screws I6. The spring members I8 may be of one piece (not shown) or they may be com prised of a heavier upper piece _2U of non-spring metal secured to a lower thin leaf spring piece 22. The purpose of the spring members, as will be more apparent later, is to aid the` recipro catory movement of the-,movable clipper plate. The device utilizes a stationary metal clipper 60 2 n ari-1,219 v plate 24 and a movable metal clipper plate 26, the latter being slightly narrower in width. Each of the plates is provided along its longitudinal edges with teeth 28, 28’ so that when the mov able plate blade is reciprocated longitudinally a clipping or shearing action between the teeth of the plates iseiiected. The stationary plate 24 is mounted on the `>supporting posts l2, ‘2f by means oi' screws 30 as shown in Figs. 2 and 4 most clearly. The `screws 30 are also used to hold the spring guides 32 in place, the inner ends of the latter being disposed between the stationary plate and the supporting posts when the device is assembled. One of these spring guides 32 is shown in per spective in Fig. 3. They have a rectangularopen ing through which the spring members I8 pass and their'purpose is to limit the outward motionof the spring members. As shown in Fig. 2, for 20 example, the ends of the stationary plate 24 have rectangular recesses 34 to permit greater movement of the spring member. The station ary plate 24 also has a central opening 36 through which the actuator 4 extends.) The opening 36 25 is large enough to permit full reciprocatory movement of the actuator Il. ~ The movable plate> 2B is disposed above the '- stationary plate 24. It is reciprocated longitudi nally by the actuator 4 which may engage a re 30 cess formed in the underside of the movable. plate. As shown in Fig. 'Z the under side of the movable plate may be provided with a rectangu lar ridge 3&3, the actuator Il engaging in the well bounded thereby; ' ` The movable plate 2@ is held against the sta tionary plate `by the ‘if-shaped upper ends of the spring members'iti, the under edges oi’ the cross portions oi which engage the upper surfaces of the movable plate adiacent small rectangular cut-outs d@ in the ends of the plate (Fig. 2).

For example, the recip rocatory movement may be effected by having a rotatable shaft on the end of which a pin is ec centrically disposed. ' This pin enga-ges a slot or recess in the movable plate. The device illustrated and described is of sim ple construction. Since the movable plate is dis posed above the stationary plate and is not cov ered by a protecting member, it may be easily replaced. At the same time it is possible for the l0 operator to usethe device by employing the same strokes as are customary with an ordinary safety razor. The operator can see at all times how the shaving is progressing and obtain an excellent shave without previous practice.
