Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. A rotary lifter is engageable with the driver blade and configured to receive torque from the drive unit for returning the driver blade from the BDC position toward the TDC position. The lifter has a body, a drive pin coupled to the body, and a roller positioned on the drive pin. The roller includes an engagement section configured to receive an end portion of a tooth of the driver blade. The lifter includes a means for aligning the engagement section with the end portion of the tooth on the driver blade to facilitate meshing between the end portion and the roller.

Abstract: A common head for use in combination with a cartridge assembly, the cartridge assembly being retained within the material containment unit of a dispensing device and arranged to discharge reactive components from larger and smaller cartridges in response to actuation of the dispensing device. The common head includes inlet openings and a rigid walled tube having a partition positioned therein to define larger and smaller pathways to enable passage of the reactive components from the cartridges into and though the common head in a predetermined volumetric ratio and prevent backflow of the components which can lead to unintended curing prior to dispensing. A flexible liner arranged for positioning within one or both pathways of the rigid walled tube is also provided to prevent such backflow and unintended curing prior to dispensing.

The second terminal portion includes a dispensing tip defining the outlet for the viscous material. The outlet has a quadrilateral profile in one embodiment. In another embodiment, the outlet has a square profile.

Abstract: An adhesive tape is arranged to be applied over the outlet opening of a nozzle otherwise arranged for dispensing a viscous material as a continuous ribbon bead onto a work surface. The adhesive tape is perforated with a plurality of perforations. By applying the inventive adhesive tape over the outlet opening of the nozzle, the viscous material may be dispensed through the plurality of perforations to form a plurality of continuous filaments on the work surface, rather than a continuous ribbon bead, resulting in waste reduction and greater control over the amount dispensed. Such viscous materials may include construction adhesives, caulking materials, sealants, dual component reactive resins, and the like. The work surface may be the base of a wall to which a length of flexible molding is to be attached by an adhesive.

When dispensing viscous material from a cartridge, the base portion is arranged for receiving the cartridge conical tip and the flange is arranged for placement between an end plate of the dispenser and the cartridge to retain said nozzle within said dispenser for dispensing viscous material from the cartridge. When dispensing viscous material in bulk form or from a sausage package, a locking plate is provided for tightly retaining the nozzle to the end cap of the dispensing device.

Abstract: A sleeve is provided which is arranged for use during loading of bulk viscous material, such as latex and silicone caulking compounds, into the barrel of a device for dispensing such compounds. The loading sleeve comprises a slightly larger open proximal end for receiving the barrel and a slightly narrower open distal end. A sidewall tapers as it extends from the proximal end to the distal end of the sleeve to create an interference fit with the barrel of the dispensing device when the barrel is inserted into the sleeve. The sleeve also includes an inwardly extending flange located at the open distal end of the sleeve to provide a seat for the barrel of the dispensing device when it is inserted into the sleeve.

Abstract: The invention relates to a container assembly that includes a built-in follow plate for loading a viscous fluid into the barrel of a dispensing device. The assembly includes a drum for holding a viscous fluid therein and a lid for fitting over the drum open top to effect closure of the drum. The assembly includes a horizontally oriented follow plate detachable from the lid. The follow plate includes a central hub arranged for receiving the barrel of a dispensing device. The follow plate moves in response to a change in the level of fluid in the drum as it is drawn into the barrel of the dispensing device.

Abstract: In one embodiment, a dispensing device includes a receptacle for containing and dispensing the flowable material, such as caulk. The dispensing device also includes a drive member which moves a piston within the receptacle for dispensing the flowable material from the device. A handle is arranged to be gripped by an operator and includes a clamp member disposed over the receptacle which is arranged to move from an open position whereby the handle is moveable to any desired position along the receptacle, to a closed position for engaging the handle to the receptacle. A user input is provided on the moveable handle and adapted to be depressed by a user for operation of the device.
