  • Patent number: 9359777
    Abstract: The present disclosure describes a taping tool for taping gaps, seams, and/or joints between wallboard members that includes a simplified tape advance/actuation assembly. The taping tool has an elongate body portion with first and second ends, and a connected head portion that directs dispensed tape toward a joint between wallboard members. The tape advance/actuation assembly has a control member forming part of the tool's elongate body portion and a tape engagement member housed by the tool's head portion. The tape engagement member moves in substantial unison with and in response to movement of the control member. The tape engagement member engages or disengages the tape depending at least in part on the position and/or direction of movement of the control member. The extent of the engagement between the tape engagement member and the tape may be adjusted though manipulation of a single fastener.

  • Patent number: 9133631
    Abstract: The present disclosure describes a handle system for use with finishing tools utilized to finish wallboard joints. A finishing tool may be connected to the handle system and moved relative to a wallboard joint to appropriately apply mastic over the joint. In one embodiment, the handle system includes an elongate handle body having a tear drop cross-sectional shape. The shape enables the handle body to fit ergonomically within a user's hand and improves the user's ability to resist torque tending to cause the handle body to twist and a connected finishing tool to come out of contact with wallboard during use. The handle system further includes a pivoting connector assembly that permits a connected finishing tool to rotate relative to the handle body and that has a unique pivot pin that allows mastic to flow through the handle body, through the pivoting connector assembly, and into the connected finishing tool.

  • Patent number: 8863807
    Abstract: The present disclosure describes a taping tool for dispensing tape and mastic over gaps, seams, and/or joints between wallboard members that includes improved creaser wheel operation. The taping tool comprises an elongate body having first and second ends, and a creaser wheel pivotally mounted near the second end thereof for creasing dispensed tape. The creaser wheel is pivotable into a plurality of positions between a first position farthest away from the elongate body's first end and a second position nearest the elongate body's first end. The taping tool also includes an actuator for receiving user input indicative of a position of the creaser wheel desired by a user. In the absence of user input, the creaser wheel is configured to reside substantially in the first position. The creaser wheel is configured to pivot from the first position toward the second position in response to the receipt of user input.

  • Patent number: 8851111
    Abstract: The controller of the plural component proportioner (10) dispenses both components (or all three if a three component material) simultaneously (at least initially) and maintains ratio at the end of each predetermined volume of material by determining which component pump (12) has reached the desired amount of travel (given the resolution available) and using a valve (16) to shut off output of that pump until the other side has caught up. At pump changeover, the output valve for that pump (12) is shut off and the air motor (12a) allowed to run until travel stops to account for cavitation, air entrainment, compressibility, or poor inlet check performance.

  • Patent number: 8826961
    Abstract: The present disclosure describes a finisher system for finishing joints, seams or gaps in wallboard. According to an example embodiment, the finisher system comprises a finisher for dispensing mastic onto wallboard and an adapter configured for pivotally connecting the finisher to a handle. The finisher and adapter are cooperatively configured to substantially prevent sliding motion of the finisher relative to the adapter, and to ensure appropriate registration and orientation of the finisher relative to the adapter. A fluid communication path is defined within the adapter, allowing mastic to flow through the adapter. A pivot pin enables a first portion of the adapter to pivot relative to a second portion of the adapter, and defines a bore therein that permits mastic to flow through the pivot pin and between the adapter's first and second portions. The adapter is configured for attachment to a handle having a substantially tear drop shaped cross-section.

  • Patent number: 6554204
    Abstract: A gun flush box is controlled by a plural component proportioning unit. When a color change is desired, the operator places the spray gun in the flush box. When a new color is selected, the control system automatically triggers the gun and flushes the gun with solvent with the flush material safely routed to a waste container. The control system automatically triggers the gun to refill the lines with new color paint without using excess paint as it displaces the flush solvent. This system is also capable of working with two guns in operation.

  • Patent number: 6543647
    Abstract: In a method for metering and mixing different components, more particularly resin and hardener, and for delivery through a spray device (6), with a first component standing under a preliminary pressure, a second component standing under a preliminary pressure and a solvent standing under preliminary pressure for the first component, the components flowing in through valves are detected through quantity measuring devices (8; 9) and supplied first to a mixer device (7) and then to the spray device (6). The one component is supplied in a predetermined quantity and the amount of the other component is controlled in dependence on the quantity of the one component by controlling the opening time of a shut-off valve (1b; 2b). Selectively the first or second component is controlled and the other component is supplied in a predetermined quantity.

  • Patent number: 6533488
    Abstract: An airless spray pump has a drive train is comprised of a motor having an output gear thereon which drives a combination gear assembly comprised of two gears mounted on a shaft which in turn drives a crank assembly which is comprised of a one-piece eccentric end gear molded together and mounted on a shaft which is supported at both ends to prevent cantilevering and attendant stresses. The crank assembly is offset from the vertical axis of the displacement pump in order to reduce side-loading thereon. A connecting rod is mounted via a pin directly to the top of the displacement rod of the reciprocating pump. Retainer pin clippingly retains the pin in the connecting rod and enables the pin to be removed for servicing without the use of tools other than potentially a screwdriver or other generic tool.

  • Patent number: 6510966
    Abstract: An air driven vibrator is attached to a robotic applicator for sealants and adhesives. When the plane of vibration is normal to the axis of the dispenser, the vibration will impart a rotary motion to the applicator. When the plane of vibration is parallel to the axis of the dispenser and normal to the direction of motion of the dispenser (such dispensers are usually robot mounted), a side-to-side or pendulum action is provided. When the dispense tip is provided with a static mixer to mix plural component materials, the vibrator will enhance the mixer's action.
