Abstract: A household slicing machine wherein a disc shaped rotary knife is mounted in a vertical plane and a guard, which is separable from the housing of the machine, is movable in a second plane that is parallel to the vertical plane of the knife between a first position in which the guard cooperates with an adjustable abutment to conceal the knife, a second position in which the knife is exposed and the machine is ready for use, and a third position in which the guard can be detached from the housing. A spring-biased locking element is reciprocably mounted in the front wall of the housing to extend into an opening of the guard when the latter assumes its second position and to extend in front of an end face of the guard when the latter assumes its first position. This prevents accidental shifting of the guard from the selected position because each such shifting must be preceded by manual depression of the locking element.

Abstract: A household slicing machine wherein a disc-shaped knife is rotatable in a vertical plane in response to starting of an electric motor as a result of depression of a trip which is mounted in the housing of the slicing machine. The trip can be depressed only when a detachable guard for the knife is held in an intermediate position in which the guard and an abutment for the foodstuff to be sliced define a gap wide enough for movement of the foodstuff into the range of the rotating knife. The guard causes a spring-biased blocking device to prevent depression of the trip when the guard is shifted to a position in which it cooperates with the abutment to prevent access to the knife as well as when the guard is actually detached or is held in a position in which it is detachable from the housing.

Abstract: High-speed spooling machines for yarn or thread are subject to the difficulty that, if the yarn or thread should break between a yarn cleaning, that is, size sensing and cutting apparatus and the takeup spool, stray remnant filamentary pieces may occur due to operation of the cutter apparatus since the thread size sensing apparatus may provide an erroneous "cut" signal upon absence of any thread in the sensing field. To prevent such operation, a thread sensing element is interposed in the path of the thread being spooled which, upon break of thread, will provide a "no tension" signal which will be below a predetermined threshold level. This signal is then used to inhibit operation of the cutter, regardless of the output of the thread size sensing element.
