Patent number: 8610396Abstract: A battery boost apparatus is described. The battery boost apparatus monitors that amount of voltage in the vehicle battery and the current flowing to the vehicle battery to determine an existence of a fault condition. If a fault condition exists, a vehicle battery is cutoff from the boost battery and the charge of the boost battery is maintained until the fault condition is remedied.Type: GrantFiled: November 8, 2010Date of Patent: December 17, 2013Inventors: Murray D. Hunter, David M. Shaver

Publication number: 20080244858Abstract: A hand-held portable vacuum having a filter indicator that is coupled to an outlet housing and in fluid communication with a portion of the outlet housing between a fan inlet and an intake. The filter indicator includes a pressure differential indicator that is configured to indicate a pressure differential between air in the portion of the outlet housing and atmospheric air pressure. The filter indicator is employed to indicate to the user of the hand-held vacuum that replacement and/or cleaning of the filter is required. The vacuum may also be used in a blower mode with a set of inflator nozzles to permit a user to inflate an article.Type: ApplicationFiled: June 17, 2008Publication date: October 9, 2008Inventors: David M. Shaver, Jacob R. Prosper, Murray D. Hunter, Carolyn Martin, Patrick W. Mooney, Olga Makeev

Patent number: 6658966Abstract: A work bench includes a frame, a bench surface on the frame with the bench surface including at least two members, one of which is movable along the frame for clamping a workpiece between the members. A mechanism for moving the member includes two screws coupled with the members. The two screws are spaced with the member for moving the member upon rotation of the screws. A sprocket is coupled with each of the screws. A transmission belt or chain is coupled with the sprockets. At least one handle is coupled with one of the screws to rotate the screws. At least one clutch is coupled with the at least one screw to limit clamping pressure on the workpiece. The clutch enables rotation of one screw with respect to the other screw so that workpieces may be clamped between the members and clamping of the workpiece may be accomplished by rotation of the screws with one hand of the operator. Also, a guard may be present which covers the transmission belt or chain.Type: GrantFiled: July 1, 2002Date of Patent: December 9, 2003Assignee: Black & Decker Inc.Inventors: Marc A. Fortin, Murray D. Hunter

Patent number: 6631535Abstract: A vacuum cleaner system having an electric powerhead with a first switch actuator component which can be actuated with a user's thumb, to turn on and off the powerhead, and a second switch actuator component which can be actuated with the user's foot, to also turn on and off the powerhead. The first switch actuator component is used when the powerhead is being used in a handheld cleaning mode. The second switch actuator component is used when the powerhead is being used in a floor cleaning mode along with an upright handle attached to the powerhead. An anti-tip over lockout system is incorporated for preventing the powerhead from being accidentally turned on when it is being held in an upside down orientation, such as during cleaning of a beater brush thereof.Type: GrantFiled: June 21, 2001Date of Patent: October 14, 2003Assignee: Black & Decker Inc.Inventors: Oleksiy P. Sergyeyenko, Murray D. Hunter, David M. Shaver, Jacob R. Prosper, Thomas Trevor Bludis

Patent number: 6581241Abstract: A vacuum cleaner system incorporating a closed loop airflow recirculation path for cooling a beater brush motor. A portion of clean, exhaust airflow created by a fan is diverted away from an exhaust port of the housing and directed into a flow path running alongside a portion of the housing. The airflow is used to pressurize a compartment within which a beater brush motor is disposed. A low pressure area created by the fan is used to assist in drawing the cooling exhaust airflow through the compartment, to thus form a closed loop cooling air recirculation system using only clean, filtered exhaust airflow to maintain the beater brush motor cool during use.Type: GrantFiled: June 21, 2001Date of Patent: June 24, 2003Assignee: Black & Decker Inc.Inventors: David M. Shaver, Oleksiy P. Sergyeyenko, Murray D. Hunter

Patent number: 6574831Abstract: A latching mechanism for an upright vacuum cleaner which allows an upright handle to be quickly and easily detached and reattached to an independently usable powerhead of the vacuum cleaner. The latching mechanism includes a pair of attachment portions formed at a lower end portion of the upright handle which cooperate with a pair of recesses formed in a housing of the powerhead. A foot actuated release lever allows the user to detach the upright handle only when the handle is in an upright orientation. The design of the attachment portions and the recess, in connection with the release lever, prevent the handle from inadvertently being installed backwards on the powerhead, as well as from being inadvertently detached from the powerhead without first depressing the release lever.Type: GrantFiled: June 21, 2001Date of Patent: June 10, 2003Assignee: Black & Decker Inc.Inventors: Murray D. Hunter, Oleksiy P. Sergyeyenko, Corey D. MacTavish, David M. Shaver, Jacob R. Prosper

Patent number: 6564423Abstract: A vacuum cleaner assembly having a two piece upright handle assembly. The handle assembly includes a recess formed at a lower end of an upper handle component and a neck portion formed at an upper end of a lower handle component. The neck portion can be engaged within the recess such that the two handle components form a rigid assembly. A pair of fastening components are securable within threaded bores formed at the area of intersection of the two handle components to form a rigid, unitary handle assembly. The two piece handle assembly can be assembled by a user without the need for any hand tools and without complicated mechanical assembly procedures. The fastening components also function to support a portion of a power cord when the power cord is wrapped therearound.Type: GrantFiled: June 21, 2001Date of Patent: May 20, 2003Assignee: Black & Decker Inc.Inventors: Oleksiy P. Sergyeyenko, Richard P. Rosa, Murray D. Hunter, Jacob R. Prosper
