  • Patent number: 6510784
    Abstract: A safety device for a food processor having a bowl closed by a cover and fed through a chute for introducing products into the working bowl, has a control switch responsive to the position of a pusher guide carrying a pusher. The pusher is slidably mounted for translation in the pusher-guide. The pusher-guide is pivotally mounted to cover over the open end of the chute, and a set of rods connect the pusher-guide to the switch operating safety rod extending along the bowl. The device prevents access of the user's hand to the cutting area, even for a large chute, by blocking the chute when the motor is enabled.

  • Patent number: 5939961
    Abstract: An electric locking device includes at least one main switch with a make contact, one secondary magnetic flexible leaf switch with a break contact, at least one auxiliary relay including at least one make contact, and an external control member comprising at least one permanent magnet. The main switch directly controls the relay coil after the secondary switch has been opened by the presence of a magnet in the control member, and the secondary switch, when it closes again, shorts the relay coil. This occurs when the control member and the magnet moves away. The assembly may be constructed such that the approach of the control member, by the presence of the magnet, first causes the opening of the secondary switch, then the closing of the main switch. The control member, during its retraction, releases the main switch that opens before the secondary switch closes.

  • Patent number: 5486665
    Abstract: The invention provides a safety switch device which is particularly adapted to increase the reliability a food processor. The switch has a piston which is slidably mounted inside a bore formed in a tapering projection in the base of the food processor so as to protect electrical circuitry inside the food processor from ingress of liquid or powder substances. The piston is spring biased and when depressed touches a contact device which is wired between an electrical power source and the food processor motor such that depression of the piston allows operation of the food processor motor. In operation the piston is depressed by a push-rod only when the bowl and the lid are properly installed on the food processor base. The piston is fitted with O-ring which resiliently seals between the piston and the bore. The piston is also formed with a skirt which surrounds and overlies a support for the contact device so that any liquid or powder substances which seep by the O-ring are directed away from the contact device.

  • Patent number: 5454299
    Abstract: A food processor has a base and a bowl. The base is arranged to couple with the bowl such that the bowl is held from moving in vertical translation by lugs fixed on the base co-operating with corresponding parts of the bowl. The bowl and base are formed with a cooperating abutment and abutment surface, respectively, which are alignable to abut and prevent the bowl from rotating relative the base.

  • Patent number: 4470788
    Abstract: A screw-extruder for shaped food pastes such as spaghetti is removably mounted on a base containing a prime mover. To ensure the safety of the assembly an activator is associated with the cylinder housing the screw and can only actuate a switch in the base when the cylinder is correctly positioned. The actuator may take the form of a manually operable pushbutton on the cylinder, or a lever acted on by the cylinder and acting as a mechanical interlock with a pushbutton and permitting its operation only when predetermined conditions are satisfied. In each case the pushbutton will only act to permit operation of the motor when it is properly positioned relative to a switch in the base.

  • Patent number: 4378730
    Abstract: A citrus fruit juicing attachment for an electrically-driven kitchen robot is described. The attachment of the invention comprises an extension piece for fitting on the motor drive shaft, a basket for mounting on the upper bowl of the kitchen robot which is provided at its edge with a projection adapted to operate a motor control switch and at least one cone which can be driven by the extension piece. The cone can only be mounted in the basket when the extension piece is not engaged therein. The need to remove basket and cone when changing cones, thus disenabling the machine, leads to an increase in safety.
