Patent number: 7475842Abstract: A power operated tape measure enables extension of a tape via a drive mechanism, as well as retraction of the tape through a mechanical decoupling within the drive mechanism. The tape measure has a housing within which is positioned a spring-biased tape assembly, the drive mechanism and a clutch. The spring-biased tape assembly includes an annular reel onto which is wound a tape having indicia for taking length measurements. The drive mechanism includes a driving gear and a driven gear, and is adapted to engage with a bottom surface of the tape to extend the tape out of the housing. The clutch is adapted to displace the driven gear out of engagement with the driving gear and thereby decouple the driving and braking force provided by the drive mechanism from acting upon the bottom surface of the tape to permit the spring-biasing of the tape assembly to retract the tape into the housing.Type: GrantFiled: January 4, 2006Date of Patent: January 13, 2009Assignee: Black & Decker Inc.Inventor: David C.

Patent number: 7415777Abstract: A power operated tape measure enables measuring tape extension through a drive mechanism, as well as measuring tape retraction. A tape cartridge assembly including an annular reel, a measuring tape wound onto the reel, as well as a spring coupled with the reel, and is positioned within a housing shell of the tape measure. A drive mechanism accomplishes tape extension out of the housing shell, and optionally, tape retraction into the housing shell by engaging with a surface of the measuring tape. A primary actuator initiates input on one or more switches that selectively control operation of the drive mechanism, and includes a lever arm for a user to make selections regarding tape extension and retraction. A retraction actuator is moveable by a user to cause the drive mechanism to become disengaged from the surface of the tape, whereby spring powered retraction of the tape is permitted.Type: GrantFiled: October 16, 2007Date of Patent: August 26, 2008Assignee: Black & Decker Inc.Inventors: David C. Campbell, Louis August Gibbons, Gavin K F Ng

Patent number: 7353619Abstract: This invention is directed to an automatic tape measure having a housing, a tape assembly, and a light assembly. The tape assembly is supported in the housing and contains a reel having a tape adapted to extend and retract from the front wall of the housing. The light assembly is received in the housing and contains a power source, a light source, a switch, and a lens. The lens is coupled with an opening in the front wall of the housing and is adapted to move between a first position where the light source passes through the lens and a second position where the light source projects downwardly onto the extended tape.Type: GrantFiled: February 12, 2007Date of Patent: April 8, 2008Assignee: Black & Decker Inc.Inventors: Louis August Gibbons, David C.

Patent number: 7284339Abstract: A power operated tape measure enables measuring tape extension through a drive mechanism as well as measuring tape retraction through at least one of a drive mechanism and spring biasing on a tape reel. A tape cartridge assembly including an annular reel and a measuring tape wound onto the reel is positioned within a housing shell of the tape measure. A drive mechanism accomplishes tape extension out of the housing shell, and optionally, tape retraction into the housing shell by engaging with a surface of the measuring tape. An actuator initiates input on one or more switches that selectively control operation of the drive mechanism, and includes a lever arm for a user to make selections regarding tape extension and retraction. The actuator may be arranged such that lever arm motion in a forward direction enables tape extension and lever arm motion in a rearward direction enables tape retraction.Type: GrantFiled: March 28, 2006Date of Patent: October 23, 2007Assignee: Black & Decker Inc.Inventors: David C.

Patent number: 7275663Abstract: A manifold includes a plurality of inlet passages provided in fluid communication between an inlet and an outlet passage. A housing retains a pressurized gas cartridge in sealed fluid communication with each of the inlet passages. A check valve is located in at least one of the inlet passages. The check valve is biased to a closed position that prevents gas from flowing through the check valve to the inlet of the inlet passage. Thus, gas cannot exit through the inlet when a pressurized gas cartridge is not sealed thereto. The housing retains a viscous product cartridge and forms a gas enclosure separated from a product enclosure by a movable wall. The gas from the pressurized gas cartridges passes into the gas enclosure and generates a force on the movable wall to dispense product from the product cartridge.Type: GrantFiled: April 20, 2004Date of Patent: October 2, 2007Assignee: Black & Decker Inc.Inventors: David C. Campbell, Allen K. Brelsford
