3 Claims.

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 same manner as the ordinary safety razor but without the use of soap or the like.

-Like a number of electric shavers now on the market, the shaver according to the present 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 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 oi.

Practically all of the manufacturers of electric 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 manipulations necessary can be mastered. With the present invention no practice is necessary since the 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 stationary and movable clipper plates are disposed 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 object 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'. Another object which is apparent is the provision 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 clipper 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 stationary plate. s

Other objects will be apparentfrom the following description'and accompanying drawings.

In the drawings:

Fig. l is an enlarged perspective view of one embodiment of the invention showing only the upper portion of the shaver to which the invention relates.

Fig. 2 is a similar view with the movable clipper plate elevated to show the manner in which the stationary plate is secured.

(Cl. lib- 43) 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.

Fig. 5 is an enlarged side elevation.

Fig. 6 is a toplplanview also enlarged.

Fig. '7 is an enlarged detail view of one manner of connecting the actuator to the moving plate, and

Fig. 8 is an enlarged side elevation of another embodiment utilizing .movable and stationaryclipper plates which are slightly curved in cross section. j

'I'he electric dry shaver illustrated inthe drawings has a handle 2 which may be of hard rubber, bakelite or any suitable insulation material. The handle preferably should becomparatively small and narrow so as to 4simulate as closely .as possible the size and shape of the handle of the ordinary safety razor. The handle houses a small electric motor (not shown) which may be of the type used in dry Shavers and which is connected by suitable -mechanism tc impart a limited reciprocatory movement to an actuator d which extends upwardly from' a rectangular well in the upper end of the handle 2.

Formed as to t in the well is a supporting 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 which extend over the -top `surfaces of the 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' supporting posts of metal or other suitable material.

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 numeral I8. These may be secured nearer thebase of the supporting posts I2, I2 by the- The spring members I8 may be of 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 movable 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 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 perspective in Fig. 3. They have a rectangularopening through which the spring members I8 pass and their'purpose is to limit the outward motion of the spring members. As shown in Fig. 2, for example, the ends of the stationary plate 24 have rectangular recesses 34 to permit greater movement of the spring member. The stationary plate 24 also has a central opening 36 through which the actuator 4 extends.) The opening 36 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 longitudinally by the actuator 4 which may engage a recess 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 rectangular ridge 3&3, the actuator Il engaging in the well bounded thereby;

' The movable plate 2@ is held against the stationary 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). The

` vertical or upright portion of the T-shaped spring members iti engage in these cut-outs. Small up-turned portions l2 adjacent the cutv outs d@ (also see Fig. 2) aid in `ireeping the movable plate in place on the stationary plate.

From the above description it is probably now apparent that the device operates in the following manner. The actuator l driven by the motor in the handle reciprocates the movable plate 2@ along its longitudinal axis. As the movable plate moves rst in one direction and then in the other, it presses the spring members lil outwardly. The spring members are tensioned so that they will aid in returning the plate to neutral position. The inward and outward movement oi the spring 'members is limited by the spring guides 32.

greater cross sectional curvature as this aids in keeping the teeth of the plates in contacting position when the movable plate is held down by the T-shaped spring members.

Naturally a reciprocatory movement of the movable plate may be/eected by means other n ari-1,219 v plate 24 and a movable metal clipper plate 26,

than the actuator 4. For example, the reciprocatory movement may be effected by having a rotatable shaft on the end of which a pin is eccentrically disposed. This pin enga-ges a slot or recess in the movable plate.

The device illustrated and described is of simple construction. Since the movable plate is disposed above the stationary plate and is not covered by a protecting member, it may be easily replaced. At the same time it is possible for the 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.

It is obvious that modicatlons of the invention disclosed can be made without departing from the inventive concept, and I do not intend to be limited except asindicated in the following claims.
