Patent number: 6311588Abstract: Self-adjusting pliers including first and second members each handle portions and jaw portions. The first member defines a rack having a plurality of teeth. A rack engagement structure is mounted to an intermediate portion of the second member and positioned adjacent the rack. During initial manual movement of the handle portions towards one another, the rack engagement structure travels in disengaged, spaced relation with respect to the rack. Then, after the jaw portions engage opposing sides of a workpiece, continued movement of the handle portions towards one another causes movement of the rack engagement structure toward the rack until the rack engagement structure engages the rack. The rack engagement structure has a movement restrictive portion being cooperable with the rack so as to limit the movement of the rack engagement structure toward the rack when the jaw portions contact one another in the absence of a workpiece therebetween.Type: GrantFiled: January 14, 2000Date of Patent: November 6, 2001Assignee: The Stanley WorksInventors: Robert A. St. John, Keith Lombardi

Patent number: 6079865Abstract: A hand mixer 30 is formed with a housing 32 and a handle 34 extending in one direction from the housing. A pair of beaters 58 and 60 can be assembled with the hand mixer 30 and rotated by a motor 88 under the control of a sensory actuator 92. A slidable compliant switch pad 44 provides an external facility for an operator to selectively position the sensory actuator 92 to operate the motor 88, and the beaters 58 and 60, at the different speeds. The sensory actuator 92 provides a tactile response to the operator during selection of the different speeds. The hand mixer 30 is provided with a first embodiment of a beater ejection mechanism 192, or a second embodiment of a beater ejection mechanism 242, for facilitating ejection of the beaters 58 and 60 from the hand mixer. A button 52 located externally on top of the housing 32 provides operational access to the operator to initiate the beater ejection process.Type: GrantFiled: April 10, 1998Date of Patent: June 27, 2000Assignee: HP Intellectual Corp.Inventors: Daniel J.

Patent number: 5996450Abstract: A pliers comprises a pair of elongated members having jaw portions, handle portions, and neck portions therebetween with the neck portions overlying each other and the jaw portions thereof having opposed clamping faces. The elongated members have oppositely arching slots in their neck portions and pivot pins which slide in the slot of the other member. The elongated members of the pliers may be fabricated as laminates of sheet metal with one neck portion extending through a passage in the other neck portion. Solid jaw inserts may be secured to the jaw portions of the sheet metal elements to provide the clamping surfaces.Type: GrantFiled: July 15, 1998Date of Patent: December 7, 1999Assignee: The Stanley WorksInventor: Robert A.

Patent number: 5957578Abstract: A food mixing appliance has a mixing head pivotably supported on a pedestal. The appliance includes a mechanism for locking the head relative to the pedestal in several discrete positions and for enabling the user to pivot the head relative to the pedestal into a selected one of the discrete positions. A mechanism includes a user actuated pivotable lever and first and second pivotable pawls. A member is fixed in position relative to the lever and includes slots defining a plurality of discrete positions for the pivotable head. Each of the pawls selectively engage a selected one of the slots corresponding to angular positions of 0.degree., 45.degree. and 90.degree. for the head relative to the pedestal.Type: GrantFiled: May 7, 1998Date of Patent: September 28, 1999Assignee: HP Intellectual Corp.Inventors: Paul R.

Patent number: 5911505Abstract: A stand mixer comprising a drive shaft, a transmission shaft, and a coupling. The drive shaft is rotatably held in a first housing. The transmission shaft is held in a second housing. The second housing is pivotally mounted to the first housing so that the first housing may be pivoted relative to the second housing. The coupling connects the drive shaft to the transmission shaft when the first housing is in an operating position. The coupling includes a self aligning coupling. The self aligning coupling comprises a first member, a second member and a spring. The first member is inserted into and intermeshed with the second member to transfer power between the drive shaft and the transmission shaft. When the first housing is pivoted to the operating position the spring biases the first member against the second member to intermesh the first member with the second member.Type: GrantFiled: November 30, 1998Date of Patent: June 15, 1999Assignee: HP Intellectual Corp.Inventors: Robert A. St. John, Ngai Ming Leung, Charles Z. Krasznai, John D. McNair

Patent number: 5908242Abstract: A stand mixer comprising a lower housing with a support rotatably mounted thereto and a mixing bowl removably connected to the support. Between the mixing bowl and the support is a self-locking connection. The self-locking connection comprises the support having an aperture and the mixing bowl having a member fixably connected to the mixing bowl. The member fixedly connected to the mixing bowl is adapted to be inserted into the aperture of the support. The member has an engagement surface formed therein. The support has a cam surface. Rotation of the support drives the cam surface upon the engagement surface of the member. This rotates the member in unison with the support and cams down the mixing bowl against the support to lock the mixing bowl to the support.Type: GrantFiled: November 6, 1998Date of Patent: June 1, 1999Assignee: HP Intellectual Corp.Inventors: Robert A. St. John, Paul R. Holbrook, John D. McNair

Patent number: 5666735Abstract: A can opener having a housing, a cutting blade, a can moving system, and a lid retainer. The cutting blade is movably connected to the housing between a cutting position and a retracted position. The lid retainer is pivotably connected to the housing between a recessed position in a recess of the housing and an extended position. The cutting blade is located in front of the recess when it is in its retracted position to keep the lid retainer in the recess. However, when the cutting blade is moved to its cutting position, the cutting blade is moved out of the path of the recess to allow the lid retainer to move from its recessed position to its extended position. The cutting blade can also push the lid retainer back to its recessed position when the cutting blade is moved back to its retracted position.Type: GrantFiled: June 22, 1995Date of Patent: September 16, 1997Assignee: Black & Decker Inc.Inventors: Richard B.

Patent number: 5539856Abstract: An electric coffeemaker includes a first electric heater for heating water for brewing the coffee. A carafe is supported on a base portion of the housing of the coffeemaker. A second electric heater is mounted in heat transfer relation with the base portion for keeping the base portion warm when a coffee-laden carafe is positioned thereon. The operation of the second electric heater is controlled to reduce the heat delivered to the base portion when a relatively lesser quantity of coffee has been brewed and to increase the amount of heat delivered to the base portion when a relatively greater quantity of coffee has been brewed. The operation of the second heater may also be varied to satisfy specific consumer taste preferences.Type: GrantFiled: January 13, 1994Date of Patent: July 23, 1996Assignee: Black & Decker Inc.Inventors: Michael A. Andrew, Walter G. Birdsell, Stephen D. Mowers, Robert A. St. John, Charles Z. Krasznai
