  • Patent number: 9687854
    Abstract: A paper shredder having shredder cover and a motor coupled to shredder blades includes a shredder throat coupled to an inlet in the shredder cover and in proximity to shredder blades. The shredder throat has a moveable throat blade, which widens the shredder throat. An anti-jam switch, which when activated causes the motor to advance the shredder blades to clear a jam in the widened shredder throat. The jam clearing mechanism can be automatic or manual, as by push-button or turn-knob linkages. A method for recovering from a shredder jam in a paper shredder is provided, including providing a moveable throat blade; sensing a shredder throat jammed condition; releasing the moveable throat blade; moving the moveable throat blade to a wide gap position; sensing the moveable throat blade in the wide gap position; advancing shredder blades in response to the sensing, by which the jammed condition is cleared.

  • Patent number: 9429197
    Abstract: A food processor or a chopper has a rotating blade, a motor, an intermediate shaft driven by the motor and an output shaft driving the blade. A first clutch member is coupled with the intermediate shaft, and a second clutch member is coupled with the output shaft. The clutch members are movable from an engaged position for driving the output shaft from the motor and a disengaged position for disengaging the output shaft from the motor. A safety interlock mechanism enables and disables the motor. A clutch lever is operable with the safety interlock to move the clutch members between the engaged and disengaged positions such that when the motor is enabled the clutch members are engaged for driving the output shaft from the motor and when the motor is disabled the clutch members are disengaged for disengaging the output shaft from the motor.

  • Patent number: 9283567
    Abstract: A shredder has a jam proof system with a thickness detector having a contact member which displaces as an article is inserted into the shredder and a resistance generating mechanism which provides a resistance force to the contact member, in response to its displacement. The greater the thickness of the article, the greater the resistance force realized. When a predetermined thickness is reached, there is a significant change in the resistance force. The resistance generating mechanism may include at least two spring mechanisms and provide feedback to the user that the inserted article may be too thick. In addition, the thickness detector may include a thickness sensor. The sensor may communicate with a controller to alert the user, and/or alter the operation of the shredder, in response to the thickness of the inserted article. For example, the controller may visually and/or audibly alert the user, or control shredder motor response.

    Abstract: A safety system prevents cutting machine operators from being accidentally carried through the infeed chute into the machine's cutting mechanism. An operator wears a safety device on his wrist and/or ankle and a sensor array mounts on opposing sides of the cutting machine's infeed chute. The sensor array elements are wound in opposite directions and connect in series opposing. The magnetic field of the safety device induces a current in the sensor array as it moves in the proximity of the sensor array. The safety system generates a signal which is proportional to the sum of the induced currents. When the signal exceeds a threshold, the safety system shuts off power to the feed mechanism and/or the cutting blades of the cutting machine, preventing injury to the operator.

    Abstract: A pre-grinder or pre-shredder apparatus, essentially made up of at least one drive unit (1) including a hydraulically or electrically driven motor (2), a reduction gear (3) and at least one shredding element (4) connected thereto and mounted on a frame (5), a wall, a feeder chute or any other mounting. The reduction gear (3) of the drive unit (1) of the pre-grinder or pre-shredder forms an element for attaching and supporting at least one shredder element (4) and is made up of a stationary portion (3?), attached directly to the frame (5) of the pre-grinder or pre-shredder or on a mounting or a wall of the latter, and by a mobile portion (3?), the shredder element (4) being inserted on the mobile portion of the reduction gear. The apparatus is useful in treating materials from any source, in particular by shredding using grinders, hammer mills or similar devices.

  • Patent number: 8528452
    Abstract: A safety system prevents cutting machine operators from being accidentally carried through the infeed chute into the machine's cutting mechanism. An operator wears a safety device on his wrist and/or ankle and a sensor array mounts on opposing sides of the cutting machine's infeed chute. The sensor array elements are wound in opposite directions and connect in series opposing. The magnetic field of the safety device induces a current in the sensor array as it moves in the proximity of the sensor array. The safety system generates a signal which is proportional to the sum of the induced currents. When the signal exceeds a threshold, the safety system shuts off power to the feed mechanism and/or the cutting blades of the cutting machine, preventing injury to the operator.

  • Patent number: 8500049
    Abstract: A shredder includes a housing having a throat for receiving at least one article to be shredded, and a shredder mechanism received in the housing and including an electrically powered motor and cutter elements. The shredder also includes a detector that is configured to detect a thickness of the at least one article being received by the throat, and a controller that is configured to operate the motor to drive the cutter elements to shred the at least one article and to set a flutter threshold higher than the predetermined maximum thickness threshold, if the detected thickness is less than a predetermined maximum thickness threshold. The controller is also configured to thereafter continuously detect the thickness of the at least one article being inserted into a throat of the shredder; and to perform a predetermined operation responsive to the thickness detector detecting that the thickness of the at least one article is greater than the flutter threshold.

  • Publication number: 20130099034
    Abstract: The present invention provides a food waste disposal system comprising a load cell located between the housing fixture and the support frame so that the load cell measures the weight of the food waste disposal system and sends the warning message to a control touch panel installed on the front upper plate of the food waste disposal system in case the user inserts more food waste than maximum allowable weight limit of the food waste disposal system. Two rotational shafts are aligned in parallel along the horizontal direction of the food waste disposal system with a screw-shaped ribbon connected to the rotational shaft by a ribbon supporter and a mixing blade is installed on at the one end of the rotational shaft, so that food waste inserted in the mixing basin is effectively mixed, crushed, decomposed and drained out through a washing chamber.

  • Publication number: 20130075505
    Abstract: The present invention relates to a mechanical food treatment processor comprising a driving block topped by a bowl. The driving block comprises a motor connected to a rotation driving means. The processor further comprises a food treatment tool with means of coupling with the rotation driving means. The bowl is topped by a lid with an opening/closing system placed on the bowl and operable to rotate about a substantially vertical axis. The lid is provided with a safety device operable to block the opening of the lid when a force, substantially parallel to the axis of rotation, is exerted on the lid. The claimed device is operable to avoid a brutal ejection of the lid and/or emissions of extreme burning steam in the event of an overpressure in the bowl.

  • Patent number: 8403556
    Abstract: A blender lid safety protection device includes a latch cover mechanism installed outside a mixing cup, such that after a lid is covered vertically onto the mixing cup, the lid is latched and fixed to the latch cover mechanism. A link rod has a compression spring coupled to the bottom of the link rod for propping the bottom of the link rod to a certain distance from one of the control switches of a power circuit control switch. After the blender lid is pressed down, the top end of the link rod drives the compression spring at the bottom of the link rod to move downward to trigger a control switch. Only after the blender lid is covered onto the mixing cup, the control switch of one of the power circuit switches will be electrically conducted, to provide a safety protection.
