Patent number: 4760940Abstract: A home carbonated beverage dispenser includes a transfer valve for conducting carbonated liquid from a carbonation reservoir to an outlet spout. A characterizing feature of the device and of the valve resides in the provision of complemental arcuate guide surfaces on the relatively movable surfaces of the valve which are brought into registry in the dispensing condition of the valve, whereby fluid flow through the valve is effected with a minimum of turbulence. A restrictor orifice is formed at the port, the orifice being defined by arcuate surfaces which mate with and provide a smooth continuation with elements of the movable valve components, thereby further to minimize turbulence and assure minimal loss of carbonation.Type: GrantFiled: June 22, 1987Date of Patent: August 2, 1988Assignee: Brewster Plastics, Inc.Inventors: Robert P. Wallace, William P. Nugent, Kenneth C. Newton

Patent number: 4726493Abstract: An improved home dispenser of carbonated beverages is disclosed, together with a novel actuator valve mechanism. The valve mechanism may be shifted from the non-dispensing to the dispensing mode with minimum of applied force by reason of the interaction between sealing gaskets carried by the valve stem and complemental gasket enveloping skirts formed within the valve, the skirts being calculated to be radially outwardly deformed by pressure applied by the gaskets.Type: GrantFiled: March 27, 1987Date of Patent: February 23, 1988Assignee: Brewster Plastics, Inc.Inventors: Robert P. Wallace, William P. Nugent, Kenneth C. Newton

Patent number: 4227290Abstract: The present invention is directed to an improved polymeric drive mandrel for the insertion of helical thread inserts into complementally tapped bores. The mandrel comprises a generally cylindrical body formed of polymeric material externally threaded for the reception of an insert, known per se, the device being characterized by the provision of a metallic drive blade extending generally axially of the polymeric portion, the drive blade including side edges juxtaposed at or intimately adjacent the roots of the threads at at least the drive end of the mandrel, whereby radial compression of the insert, experienced in the course of the driving thereof, is prevented from damaging the lead thread portions of the mandrel and driving torque is distributed over an extended length of the mandrel.Type: GrantFiled: May 7, 1979Date of Patent: October 14, 1980Inventor: Robert P.

Patent number: 4077101Abstract: The present invention is directed to an improved driving mandrel for insertion of spiral thread inserts into complementally tapped bores. The mandrel comprises a generally cylindrical structure having a drive tooth at one end for engagement with the tang of an insert, the device being characterized by its being formed of a resilient polymeric material having rigidifying means located at a zone adjacent the drive end, whereby the body portion of the mandrel beyond the zone is subject to limited deflection under torsional and lateral displacing forces. In accordance with a preferred embodiment, the mandrel includes a readily compressible zone in registry with the trailing end of the insert, whereby the insert may be supported against elongation and yet be free to contract as it is driven into the bore, greatly reducing the possibility of cross threading.Type: GrantFiled: June 3, 1976Date of Patent: March 7, 1978Inventor: Robert P. Wallace
