  • Patent number: 7530510
    Abstract: A food processor for processing foodstuffs includes a housing with a motor disposed therein. The motor causes rotation of an output shaft extending outwardly from the housing. At least one food processing tool is removably engageable with the output shaft to rotate therewith. At least two interchangeable storage containers individually attach with the housing. An open end of the storage containers is attached to the housing, so that, with one of the storage containers attached to the housing, the at least one food processing tool extends toward the open end and at least proximate the interior of the attached storage container for the processing of foodstuffs therein. The storage container is detachable from the housing to store the processed foodstuffs therein, and another storage container is attachable to the housing for the processing of other foodstuffs within an interior of the other storage container.

  • Patent number: 7481386
    Abstract: A wood chipper includes an engine and a cutting assembly. A rotatable feed wheel and a gap-bounding member define therebetween an adjustable gap through which feed material moves toward the cutting assembly. An electronic control unit (ECU) controls force applied to the feed wheel or gap-bounding member toward the feed material in response to an operational condition of the wood chipper. The ECU can maintain or vary the force in any desired manner. One option is to apply the force with a pulsating mechanism in a pulsating manner to enhance the feeding procedure. The pulsating mechanism is in communication with a sensor from which the ECU receives signals typically indicating an operational speed of the cutting assembly or the engine. An ECU logic circuit permits the pulsating force only if the operational speed exceeds a predetermined threshold.

  • Patent number: 7472646
    Abstract: A domestic appliance comprising at least one housing part with a detent element and at least one second housing part with a detent counter-element. Said elements are designed to interconnect the housing parts and are associated with a locking element, which is used to secure the detent elements, when the locking element is in the locked position, from becoming detached from the detent counter-elements. The aim of the invention is to facilitate the assembly and disassembly of the detent device. To achieve this, the locking element comprises a first end that is supported on one of the housing parts and a second end that engages with the detent element in the locked position. The locking element can thus be pivoted back and forth in a simple manner between a release position and a locked position, facilitating a more rapid, simpler assembly and disassembly.

    Abstract: A multi-functional food processor contains a machine body and a top cover. It further includes a container and a driving device. The drive shaft of the driving device is extended to the container, and a juicer shredder, a vegetable shredder or a meat grinder blade is selectively installed in the transmission shaft, which is connected to the drive shaft. The top cover is provided with two feed tubes, where the first feed tube is used for feeding vegetables and fruits in conjunction with a first pusher. The second feed tube is used for feeding vegetables or meat into a vegetable shredder or a meat grinder blade in conjunction with push of the second pusher. A safety switch is mounted between the feed tubes, and it allows only one pusher to operate in each sole feed tube thus avoiding the food being fed into the wrong feed tube.

  • Patent number: 7441718
    Abstract: A wood chipper or grinder includes counter rotating upper and lower feed drums driven by a hydraulic motor at variable fluid pressure to produce variable torque to the feed drums. Wood debris fed to a gap between the rollers is advanced toward a grinder or chipper to reduce the material. A hydraulic feed control system operates off the variable hydraulic pressure associated with the motor and, in an automatic mode, exerts more or less downward clamping pressure on the upper feed drum with changes in pressure to the motor. The system sets an upper limit on the clamping pressure in the automatic mode which can be overridden manually if necessary to apply greater downward force than that achievable in the automatic mode. The upper feed drum can also be manually raised if necessary.

    Abstract: The present disclosure relates to a wood chipper that has a feed roller driven by a hydraulic motor. Hydraulic fluid under pressure is provided to the motor through a two-stage pump, providing separate flows of fluid under pressure. The flows of the pump stages are combined for normal operation of the chipper. A bypass that will bypass the flow from one pump stage when the pressure of the fluid under pressure driving the motor exceeds a pre-selected level from increased load on the feed roller is provided. When the bypass is open the feed roller is slowed to reduce the feed rate of material into the chipper, and when the feed roller loads reduce, the flows will again be combined to speed up the feed roller.

  • Patent number: 7063282
    Abstract: The present invention concerns a chipping or crushing apparatus having a prominent speed of rotation and mass inertial moment. The main parts of the apparatus include a chipping disc or a rotor, a short circuit motor and a frequency converter connected to the circuit of the motor. From the chipping disc, respectively from the rotor or from the motor there is arranged a data connection of the speed of rotation to the frequency converter, and the frequency converter has been arranged to control the frequency of the motor current by means of said data so, that in a situation of peak load, when the motor load (torque M) has reached the nominal load, the frequency converter keeps the motor load at the nominal load by decreasing the frequency of the motor current. Thereby kinetic energy of the rotating components will be released for use in the peak loads corresponding to the decrease of the speed of rotation.

  • Patent number: 7044409
    Abstract: An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled.

  • Patent number: 6976516
    Abstract: A two-part blade support base for mounting a chipper knife to a chipper disc wherein the parting line between the upper part and lower part is substantially parallel to a plane defined by the chipper disc. The parting line incorporates a vertical step which transmits shear forces which would cause the upper part to move outwardly of a chip receiving surface. A screw or bolt connects the upper and lower parts of the blade base. The upper part of the blade base may be constructed of a wear resistant material.

  • Patent number: 6907819
    Abstract: A locking system for an appliance has lid and feed chute locking components that include a spring-biased, ramp surfaced pivoting arm that is adapted to be activated to extend or retract a rod that activates or de-activates a motor drive of a food processor. The arm is activated by rotational movement of the lid relative to the bowl, as an extension member attached to the lid, which is activated by insertion of the plunger, extends downwardly from the lid and engages the ramp surface of the pivoting arm when the lid is rotated. Thus, the plunger can remain inside of the food chute of the lid while the lid is removed or replaced.
