Abstract: The apparatus includes a stick allowing a handling in a standing position and which is to be held obliquely directed to the floor, and a bearing body is mounted to the lower end of the stick in which a first pivot axis is supported which at its lower end is rigidly mounted to a joint body in which a second pivot axis is supported by means of which a supporting body consisting of a disk is located relative to the joint body. An applying spatula is exchangeably mounted to the supporting body. An operating rod is pivotably mounted to the end of the joint body which at its other end is pivotably mounted to a lever which is pivotable by means of a mounting member located roughly halfway along the longitudinal extent of the stick. By means of such also the joint body and accordingly the applying spatula mounted thereto via the supporting body is pivotted about an angle of less than 180.degree.

Abstract: A conventional cutter is disclosed. It features a plate to secure the blade. There is also a blade magazine of relative conventional design.

Abstract: The hair-cutting appliance comprises a blade held interchangeably in a two-piece housing and located between a stationary row of teeth at the edge of the lower part of the housing and a row of teeth adapted to be moved back and forth in relation to the blade. A retaining arm, with a razor-blade head secured interchangeably thereto, is mounted pivotably at the edge of the housing remote from the blade and the razor-blade head is adapted to pivot outwardly from a nonoperative position within the housing, through an aperture in the lower part thereof, into an operative position. When the razor-blade head is in use, the housing of the hair-cutting appliance serves as a handle. The hair-cutting appliance therefore performs a dual function, since it may be used not only for cutting hair, but also for shaving.

Abstract: The knife with an extensible and retractable blade has a hollow knife grip and a blade magazine with a plurality of superposed blades therein. With the aid of two entraining members in the form of a pusher bar and two gripper arms of a blade-changing device which slides with the entraining members along two sides of the blade magazine, on pulling the blade-changing device out of the knife grip a used blade is guided by gripper arms back into the blade magazine and on pushing the blade-changing device back into the knife grip, the new blade is pushed out from the blade magazine by means of the pusher bar in the direction towards the front end of the knife and into engagement with a blade-pusher. The blade pusher has a pin arranged at the end of an arm which engages in a hole in the blade. Then with the aid of the blade pusher the blade may be extended to a greater or lesser extent from the knife grip or may be fully retracted into it and arrested in various stop or detent positions.
