This invention relates to a mot-or driven shaver and more particularly to a dry shaver having rotary cutter
elements individually mounted on the user’s ?ngers. An object of my invention is to provide a motor driven shaver which shall embody an electric power unit opera tively connected to a plurality of rotary cutter elements which in turn are detachably connected to the ?ngers of a user.

Referring now to the drawing for a better understand ing of my invention, 1 show an electric motor indicated generally at 10‘ having an outwardly projecting motor 10 shaft 11, as shown in FIG. 2. Power is supplied to the motor 10 by suitable means, such as an electrical cord

The ‘I Another-object of my invention is to provide a motor

driven shaver of the character designated which shall have ?nger-tip control and one in which the user has a natural
feeling of position due to the fact thatthe rotary cutter elements are carried by and moved with the ?nger-tips of a user.
A still further object of my invention is to provide a
gear 18 also meshes with a gear 23 mounted on a stub
shaft 24 which in turn is also mounted in bearings 22. As shown in FIG. 2, the bearings 22 are also carried by
35 the housing for the motor 10.
The outer ends of the shafts 11, 19, 21 and 24 are pro vided with an axially extending recess 26 adjacent the outer ends thereof for receiving one end of a ?exible drive shaft 27, as shown in FIG. 6. The ?exible drive shafts 27 are each surrounded by tube-like housings 28 which are formed of a suitable ?exible material to permit
free movement thereof. The tube-like housing 28 is pro motor driven shaver of the character designated which vided with an enlarged diameter portion 29 which tele shall be simple of construction, economical of manufac scopes over an outwardly projecting sleeve 31 carried by ture and one which produces a massage action as the 45 the motor housing, as shown in FIG. 6, whereby the tube rotary cutter elements are moved over the surface being like housing is attached ?rmly to the motor housing. shaved. As shown in FIG. 5, the end of each ?exible shaft Heretofore in the art to which my invention relates, 27 opposite the end thereof operatively connected to many types of electric shavers have been proposed.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited but is susceptible of various changes and
with a minimum of effort.
The loop-like members 41 are
preferably formed of separate sections, as shown, whereby the size thereof may be varied to ?t ?ngers of various
modi?cations without departing from the spirit thereof, and I desire, therefore, that only such limitations shall
