8 Claims.

This invention relates to improvements in mechanized or dry Shavers.

It is a known fact that in all mechanized or dry shavers substantially all of the clippings of whiskers or hairs lodge in the cutter head. Usually such clippings are removed from the interior of the head by means of a brush, but it has been found from experience that this manner of cleaning is ineifective because the brushes so employed wear out quickly or are readily lost. Also, at least one of the large commercial mechanized razor manufacturers has recommended that no brushes be used because of the inherent danger of mutilating the cutting head, which they found from experience frequently occurs. It was to provide a means for automatically removing the clippings from the interior of the shaving head that this invention was designed.

The main objects of this invention are'to provide a cleaning element for automatically removing hair clippings from the interior of a shaving head of a mechanized or dry razor; to provide means of this character which may be readily inserted into the interior of the head of a mechanized razor without altering or changing the usual razor head itself; to provide means of this character which is loosely positioned within the razor head and arranged to vibratably reciprocate by the frictional contact of the means against the inner movable cutter member of the razor head; and to provide an automatic cleaner for mechanized or dry shavers which is simple in construction, readily adapted to a mechanized razor head, and inexpensive to manufacture.

A specic embodiment of this invention is shown in the accompanying drawing in which:

Figure 1 is a side view of a mechanized razor, a part thereof being shown broken away to illustrate the seating of a razor head.

Fig. 2 is a vertical cross-sectional View taken on the line 2-2 of Fig. 1.

Fig. 3 is a cross-sectional view taken on the line 3--3 of Fig. 2.

Figs. 4, 5 and 6 are top, side and end views respectively of the cleaner element to which this invention is specically directed.

As the modern tendency is 4to close up the ends of the outer stationary cutter and provide some means for collecting the clipped hairs, I have shown this type of razor case or housing in the drawing. The case l is provided with the usual motor or vibrator, not shown, and is cut out at its upper end to receive and form a seat for the stationary outer or face bearing elongated U-shaped cutter 2 and inner or movable U-shaped cutter 3. The outer cutter `3 is seated in the casing between the two end members 4 and 5 respectively and the outer cutter is usually removably secured therein by suitable means such as screws or the like, not shown. The inner cutter' 3 is arranged to reciprocate within the outercutter 2. Reciprocable motion is imparted to the inner cutter 3 by the motor or vibrator, not shown, through the pivoted arm 3, the upper end of which is loosely journaled to the lower medial portion/Vl of the inner cutter 3. The inner cutter Yis adapted to be reciprocated within the outerstationary cutter 2 by the motor or vibrator, not shown, and to eliminate as much friction as possible between the inner and outer cutters, I employ a ball bearing 8 seated in the bottom of the outercutter'l- The inner cutter 3, provided with track 9, rides on saidball'bearings 8.

The automatic cleaner device to *which* this invention is directed comprises a `metal vwire or band bent substantially rectangular in shape but with the ends thereof projecting outwardly to blunt points I0 and Il (see Figs. 3i andf5). In the form shown the upper and lower or substantially parallel long side members I2 and I3 of the cleaner are bentin zigzag orundulated Vform and are also transversely arcuate in shape.

The, zigzag or undulated form isV applied tothe upper and lower'meinbers in such a manner that the undulations occur in two planes that are normal to each other. For example, in the horizontal plane the undulations travel to and fro laterally and in the vertical plane the undulations 'travel up and down along the length of the upper and lower members.

The cleaner is inserted in the razor head and within the inner movable cutter. It can now be seen that as the inner cutter is reciprocated the cleaner will vibrate and reciprocate by the mere frictional engagement of the cleaner against the walls of the reciprocating cutter 3 to thereby effectually agitate the hair clippings falling within the interior of the inner cutter. In the form shown one end of the inner cutter is provided with an end wall M thereby, when the inner cutter is reciprocating, causing the clipped hairs to be agitated and discharged through the open end of the inner cutter into the clipping chamber l5. I have provided a shiftable cover plate I6 to prevent the clipped hairs from falling out of the chamber until the cover plate is removed.

It is to be understood that the cleaner may be modified to assume numerous shapes and forms,

for instance, the blunt points may be eliminated, the undulations may be Varied etc.

Although but one specific embodiment of this invention is herein set forth, it is to be understood that some of the details may be altered or omitted Without departing from the spirit of the invention as defined by the following claims.

I claim:
