"Razor";

Razors with rotating blades known Baaart, Electric razors in particular are suitable for plane cuts, but this is not possible with them Make 3 aqon cuts, for example on the hair of the head shave the ears in a straight line *

The main purpose of the invention is to make the power razors usable for straight cuts, and essentially consists in converting a gear, in particular a crank mechanism, the rotating movement of the drive shaft into a reciprocating movement or the knife In order to be able to use any existing razor with rotating knives for this purpose, a device adapted to the device is also provided according to the invention with a gear that converts the present movement into a reciprocating motion of the knife, which can be replaced instead of a device used rotating knives can be used in the apparatus. With this simple, attachable additional device, every additional device, such as a knife, faconson device or the like, can be saved.

In the drawing, an embodiment is in game of the invention shown, namely:

Fig. 1 is a longitudinal section and

Pig. 2 is a plan view in section along line 2-2 of Fig. 1. ■

In the housing 10 of the razor the drive shafts 11 and 12 are mounted, in the usual way the rotating ones Knives are attached. In the drawing, however, the additional device is cap-shaped on the housing 10 by means of its outer Retaining ring 14 with the interposition of an inner one Retaining ring 15 placed. Between the two retaining rings 14 and 15, the guide ring 16 and the blind disk 17 are inserted and the two retaining rings are connected clamped by means of the screws 18. In the guide ring 16, the drive pulley 19 'runs with the drive shaft 11 is positively connected, e.g. by means of a square, while in a recess 21 of the blind disk 17 the other drive shaft 12 rotates freely.

The drive pulley 19 has a crank pin 22 which engages in an elongated hole 23 of the rocker arm 24. The plate 25 of the additional device is placed on the outer retaining ring 14 and fastened to the retaining ring 14 by means of grub screws 25ä. With the plate 25 _o i $$ .- | the removable lower blade / fixedly connected by means of screws 26 27th Ea carries a bearing and guide pin 28 on which the rocker arm 24 is pivotably mounted. An adjustment switch 29 on the bolt 28 serves to support a spring 30 which presses a pressure plate 31 against the upper knife 32 and the latter against the lower knife 26.

To. Removal of the usual shaving head (not shown in the drawing), the accessory device comprising parts 14 to 37 is placed as a whole by means of its retaining rings 14 and 15 on the shaver body 10, the drive shaft 11 being positively coupled to the drive pulley 19. With each rotation of the drive pulley V , the rocking lever 24 is set in a reciprocating motion by the crank pin 22 engaging in the elongated hole 23 by swinging around the pin and thereby the upper knife 32 pressed by the spring 30 against the lower knife by means of the pin 33 also issued a corresponding reciprocating motion. The ones moving rapidly towards and towards one another
