Patent number: 4827989Abstract: A wood chipper (40) for chipping wood, such as logs, into wood chips, has a chipping block (80) including one or more chipping knives (96) rotatably mounted in a housing (42l). An input aperture (60) on one face of the housing (42) receives material to be chipped, and a discharge chute (58) extends tangentially from the periphery of the housing (42) to exhaust chips therefrom. Primary and secondary wear blocks (68, 69) having hardened wear surfaces, are mounted at the input aperture (60) of the housing (42), against which incoming wood material abuts as it is fed into the chipper (40). The primary wear block (68) is mounted on a support bracket (66) and adjustable relative to the axial position of the chipper knives (96). The secondary wear block (69) is adapted to be mounted to the housing (42) at an inward edge of the input aperture (60), so that it can be easily removed.Type: GrantFiled: March 11, 1988Date of Patent: May 9, 1989Inventor: Donald E.

Patent number: 4824029Abstract: An improved operating interlock is included in a food processor having a drive motor and a control switch which must be operated by the interlock to enable the operation of the drive motor. A shaft projects upwardly through a working bowl of the food processor and is coupled to the drive motor for rotation of a food processing tool coupled to the shaft within the bowl. A bowl cover is detachably secured to the bowl and defines a feed tube for introducing food items through the bowl cover into the bowl. A feed tube cover is detachably secured to the bowl cover for movement between a closed position over the feed tube and an opened position. The improved operating interlock further defines a child-lock for securing the feed tube cover to the bowl cover and the bowl cover to the bowl without enabling operation of the food processor such that one or more food processing tools can be enclosed within the bowl to discourage inadvertent contact with sharp tool portions when the processor is not in use.Type: GrantFiled: January 7, 1988Date of Patent: April 25, 1989Assignee: Whirlpool CorporationInventors: Richard L. Stottmann, Edward F. Ponikwia

Patent number: 4821616Abstract: This machine is of the type comprising a frame (1) supporting a hopper (2) for charging the products, a cutting plate, an ejection plate (6a, 6b) for ejecting the cut products disposed under the cutting plate (4), and a device (13) for driving in rotation the cutting plate and the ejection plate. According to the invention, the ejection plate is driven in rotation in a direction opposed to that of the cutting plate. Advantageously, the speed of rotation of the ejection plate is higher than that of the cutting plate.Type: GrantFiled: October 13, 1987Date of Patent: April 18, 1989Assignee: DITO - SAMAInventors: Marcel Mayeux, Christian Lallier, Joel Musseau

Patent number: 4819882Abstract: An improved food pusher support is provided for a food processor having a primary feed tube for introducing food products into the processor and a feed tube cover including an opening for slidingly receiving a primary food pusher by means of compression leaf springs formed into the feed tube cover for engaging elongated ramped projections extending axially along the primary food pusher. In one instance, the projections are formed adjacent the food pushing portion of the primary food pusher such that the primary food pusher can be retained in a raised position for movement of the feed tube cover relative to the feed tube. In another instance, the primary food pusher comprises a hollow shaft defining a secondary feed tube therethrough and a secondary food pusher securably and slidably engageable with the hollow shaft.Type: GrantFiled: January 7, 1988Date of Patent: April 11, 1989Assignee: Whirlpool CorporationInventors: Richard L. Stottmann, Edward F. Ponikwia

Patent number: 4817481Abstract: A cutting device for cutting a vegetable and the like including a cup-shaped lower housing, an inverted cup-shaped upper housing with a connecting apparatus for connecting these housings, a cutter disk arranged in the lower housing, and a fixing apparatus attached to the lower housing. These housings, the disk, and the fixing apparatus can be disassembled from one another. The upper housing can be detached from the lower housing by releasing the connecting apparatus. The manually operated cutter disk can be lifted and removed from the lower housing. The lower housing also can be disassembled from the fixing apparatus, which has a sucker member operated by a lever.Type: GrantFiled: March 8, 1988Date of Patent: April 4, 1989Assignee: Kabushiki Kaisha HonmaInventor: Shinobu Homma

Patent number: 4817878Abstract: Power lock tool retention apparatus for a food processor includes at least one flattened section on the drive shaft with an associated horizontal notch. A socket extending downwardly on the inside of the rotary tool hub is placed onto this drive shaft during manual installation of the tool so that rotation of the shaft will cause the tool to be rotated. At least one horizontal lip is provided in the socket at an elevation to become aligned with the notch on the drive shaft when the hub has been slid down vertically into its operating position on the shaft. The socket configuration is complementary to, but slightly different from, the flattened configuration of the drive shaft in order to permit a small amount of relative angular movement between the shaft and hub when the shaft commences to rotate.Type: GrantFiled: September 7, 1983Date of Patent: April 4, 1989Assignee: Cuisinarts, Inc.Inventor: Koichiro Shibata

Patent number: 4799626Abstract: The invention is directed to a food processing apparatus (2) having a lid (22) adapted to be placed on a vessel (10), with a cover member (26) of semi-circular cross section and having a passage (24) opening into the vessel (10) being provided on the lid. The cover member (26) is provided with a vertically extending rectangular receiving opening (32) for receiving a semi-cylindrical receptacle (34) adapted to swivel through 180.degree. between a loading position and a discharge position. The receptacle (34) is adapted to receive whole fruits (45) without the operator contacting the shredding or cutting tools (12, 13), because the receiving opening (32) is closed in the loading position of the receptacle (34). Following loading of the fruits (45) into the receptacle (34), the latter is swivelled through 180.degree.Type: GrantFiled: October 13, 1987Date of Patent: January 24, 1989Assignee: Braun AktiengesellschaftInventors: Sigrun Hickel, Wolfgang Franke

Patent number: 4784337Abstract: A chipper for cutting uniform chips from a log having a rotating disc containing a plurality of radially disposed cutting stations, each having a knife assembly positioned adjacent a chip slot. Each knife assembly has an elongated cassette having a knife receiving recess formed in the top front surface thereof. A reversible knife is located in the recess by means of a key and is held in place by a retaining bar so that one cutting edge of the knife is accurately positioned at the entrance to the chip slot. Reversing the knife in the cassette after the first edge becomes dulled similarly positions the second cutting edge. Preferably, a plurality of knives are mounted end to end in the cassette.Type: GrantFiled: September 21, 1987Date of Patent: November 15, 1988Assignee: Carthage Machine Company, Div. of Industrial General CorporationInventors: Timothy P.
