Patent number: 8870093Abstract: A pneumatic dispenser for dispensing viscous material, for example, mastic caulk, from a container is described. The dispenser comprises a fluid supply arrangement for accepting a dispensing nozzle of the container and providing a flow of pressurized fluid to the dispensing nozzle to enable the material to be dispensed as a spray. A moveable member can be used to control the flow of pressurized fluid, for example a member disposed on a cap for closing a container containing compartment of the dispenser and/or a moveable member disposed around the dispensing nozzle. The arrangement of the fluid supply arrangement allows for convenient control of the pressurized fluid flow for spraying the material. Also disclosed is a dispenser with a readily exchangeable pressure application interface for applying a dispensing pressure to the container, enabling the dispenser to be used with both cartridge and foil pack containers.Type: GrantFiled: December 23, 2011Date of Patent: October 28, 2014Assignee: P.C. Cox LimitedInventor: Richard Brummitt

Patent number: 8616415Abstract: A pneumatic dispenser is provided comprising a handle with an actuation arrangement comprising two actuation surfaces, each for actuation by an operator holding the handle to selectively apply pressure to a respective one of the front and rear chambers on either side of a piston couple to a rod for applying a dispensing force, thereby controlling advance and retreat of the rod. Further, a valve is provided comprising a body and first and second moveable members. The valve can be arranged as a space saving five port valve for use in the disclosed dispenser. Additionally, a dispenser comprising a stock portion and a cylinder secured to the stock portion is disclosed. Pressure is supplied to the rear chamber of the cylinder from the stock portion through its front chamber and the piston moveable inside the cylinder.Type: GrantFiled: December 23, 2011Date of Patent: December 31, 2013Assignee: P.C.

Patent number: 8607824Abstract: A valve for a pneumatic dispenser, the dispenser comprising a handle with an actuation arrangement for selectively applying pressure to a respective one of the front and rear chambers on either side of a piston coupled to a rod for applying a dispensing force, thereby controlling movement of the rod. The valve is provided with a body and first and second moveable members moveable relative to the body. The valve can be arranged as a space saving five port valve instead of two three port valves for use in the disclosed dispenser and can be arranged to provide a fail safe mechanism if both valve members are actuated concurrently. A dispenser comprising a stock portion and a cylinder secured to the stock portion is disclosed. Pressure is supplied to the rear chamber of the cylinder from the stock portion through its front chamber and the piston moveable inside the cylinder.Type: GrantFiled: December 23, 2011Date of Patent: December 17, 2013Assignee: P.C. Cox LimitedInventor: Richard Brummitt

Patent number: 8528793Abstract: An actuator for advancing a rod which enables release of the rod from an actuating mechanism by rotating the rod to allow the rod to be retreated. The actuator may also provide a mechanism for disabling the driving mechanism as the rod is fully advanced to prevent damage by excessive forces being applied to the rod. The actuating mechanism can be fully enclosed in a stock of a dispenser gun or applicator, facilitating cleaning of the dispenser gun. The disclosed dispenser gun is particularly suitable for dentistry applications.Type: GrantFiled: December 27, 2010Date of Patent: September 10, 2013Assignee: P. C. Cox LimitedInventor: Richard Brummitt
