Patent number: 8241427Abstract: A floor tool is provided, and includes a handle with first and second opposite ends through which a longitudinal axis of the handle extends, and a mop head coupled to the second end of the handle. In some embodiments, a fluid container is coupled to and carried by the handle at a location between the first and second ends of the handle. The fluid container can have a center of mass offset from the longitudinal axis. In some embodiments, a portion of the handle is located between the fluid container and the first end of the handle, and is offset from the longitudinal axis more than center of mass of the fluid reservoir. The floor tool can also have a valve coupled to the handle and having a gap into which a length of conduit extending from the fluid container can be laterally inserted. A valve-actuating trigger can be coupled to the handle for rotation, such that the trigger pivot point is closer to the second end of the handle than the terminal end of the trigger squeezed by a user.Type: GrantFiled: April 29, 2008Date of Patent: August 14, 2012Assignee: Diversey, Inc.Inventors: Charles A. Crawford, Andrew M. Bober, Craig Conner, Mark Cors, Nicholas Reback, Daniel Lee

Patent number: 8205297Abstract: A swivel castor assembly, includes a body having at least one rotatable wheel engageable with a floor or ground surface below the body, a brake actuable to brake or prevent rotation of the wheel, and an element for mounting the body such that it is able to swivel about a generally upright axis. A head is adapted to be mounted to prevent or restrict its rotation about the upright axis. A brake activator is mounted to the head for movement between a braking position in which it activates the brake, a neutral position in which the brake is inactive and the body is not prevented from swivelling about the upright axis, and a direction-lock position in which the body may be swivelled to one of plural selectable orientations with respect to the head at each of which the body is locked against swivelling but the brake is inactive.Type: GrantFiled: June 6, 2008Date of Patent: June 26, 2012Assignee: Fallshaw Holdings Pty LtdInventors: Andrew Fallshaw, Andrew Charles Crawford, Mathew Keith Trainor, Brent Matthew Strahan, Kenneth Harrison

Publication number: 20120132875Abstract: Apparatus and method for use in handling a load, the apparatus comprising a load bearing elongate member (2) and a load bearing mechanism for paying out and recovering the load bearing elongate member; at least one service umbilical (9, 10) and a mechanism (12) for paying out and recovering the service umbilical; at least one securing member, and a wrapping device (15, 16) for rotating the securing member around the load bearing elongate member and the service umbilical as they are being paid out and to unwrap the or each securing member from the load bearing elongate member and the service umbilical as they are recovered. The rotation of the securing member by the wrapping device is powered by power supplied via a power conduit (25) in the form of an elongate flexible conduit wrapped onto a power conduit drum that has a central axial bore arranged concentrically with the load bearing elongate member during handling of the load.Type: ApplicationFiled: August 2, 2010Publication date: May 31, 2012Applicant: Deep Tek IP LimitedInventor: Alexander Charles Crawford

Publication number: 20110262205Abstract: A floor finish applicator including a cart having wheels and a body member constructed and arranged to receive a source of floor finish. The floor finish applicator also includes a pump coupled to the cart and operable to deliver floor finish to a floor, a floor finish feed conduit in fluid communication between the pump and a container supporting floor finish, and a transmission assembly coupled to the cart. The floor finish feed conduit supplies floor finish to the pump. The transmission assembly includes an axle coupled to and driven by a wheel of the cart, a drive gear connected to the axle, a drive shaft having a driven gear for engaging the drive gear and driving the pump, and a hand-actuated spring-loaded clutch for selective engagement of the pump and the drive shaft with the axle.Type: ApplicationFiled: June 10, 2011Publication date: October 27, 2011Applicant: DIVERSEY, INC.Inventors: Andrew M. Bober, Charles A. Crawford, Lance D. Brown, Douglas S. Rodenkirch, Scott I. Biba, Craig P. Conner, Daniel R. Nett, Nicholas S. Reback

Patent number: 8001756Abstract: Apparatus and a method for handling an elongate member such as a cable between two points has a support line extending between the points, and winch mechanisms and wrapping devices at each of the points, to permit the elongate member to transit between the two points in a wrapped bundle that is supported mechanically against damage and deviation from a controlled path between the points, and to permit the bundle to be unwrapped at the second point for further manipulation of the elongate member. The invention is particularly useful in raising and lowering a load, towing, and also handling service cables, tubes, pipes, hoses or other elongate lines that are connected between two points. A preferred embodiment is described for the subsea deployment of wireline and the deployment of signal and power cables to subsea wells.Type: GrantFiled: October 4, 2007Date of Patent: August 23, 2011Assignee: Depp Tek IP LimitedInventor: Alexander Charles Crawford

Patent number: 7950297Abstract: An inspection head where non-destructive inspection is structured to fit into narrow spaces, and to accurately and repeatably move an inspection probe along a surface to be inspected. Movement of the inspection head along an X, Y, Z, ?, and ?-axis is precisely controlled by individual drive mechanisms.Type: GrantFiled: July 11, 2007Date of Patent: May 31, 2011Assignee: Siemens Energy, Inc.Inventors: Charles Crawford Moore, Michael Charles Moore, Michael F. Fair, James A. Bauer, Michael J. Metala

Patent number: 7946521Abstract: A winch drum assembly has a barrel to receive a line, and a spooling device for guiding the line onto the barrel. The line is wound onto the barrel at a point that moves axially with respect to the barrel, and the orientation of the line on the barrel is adapted to change at least once per revolution of the barrel, so that radially adjacent layers of line are non-parallel. Spooling gear is described for guiding the line and the barrel can have ramps and walls to guide the line in the different directions. Non-parallel layers of line exhibit a reduced tendency to interfere with one another, so that the spooled line comes off the barrel more consistently.Type: GrantFiled: February 1, 2008Date of Patent: May 24, 2011Assignee: Deep Tek Winch IP LimitedInventor: Alexander Charles Crawford

Publication number: 20100047459Abstract: A floor finish application tool and method for applying floor finishes to a floor. Some embodiments are provided with disposable or quickly replaceable features, such as feed lines or reservoirs to eliminate the need for time consuming clean-up operations. Some embodiments are provided with a two portion hinged head having a spreading or distributing portion and a leveling portion to provide substantially uniform floor finish thickness across a floor. Some embodiments also feature an applicator pad composed of at least two different types of material. The first material is a floor finish distributing material that serves a function of substantially uniformly spreading bulk floor finish across a floor. The second material is a floor finish finishing material that is suitable for leveling the already spread floor finish.Type: ApplicationFiled: December 20, 2007Publication date: February 25, 2010Applicant: JOHNSONDIVERSEY, INC.Inventors: Charles A.
