Multiposition valved dispenser
First Claim
1. A multiposition valved dispenser for use with a pump and tap assembly of the type used for kegs, comprising:
- on said pump and tap assembly, means for coupling and a flexible tube connected to said means for delivery of the keg fluid by way of said tube,and further comprising;
a valve having means for effecting on states and an off state with respect to fluid flow, said valve including,a housing, a spigot mounted on the housing for delivery of the fluid by said dispenser and means for coupling said flexible tube to the housing for delivery of the fluid to the valve;
a first handle member rotably mounted on the valve for controlling the valve'"'"'s on states by angular displacement of said handle away from a pre-determined off position with respect to the valve housing,a second handle member detachably mounted on the first handle for moving same, and angled from said first handle so that said second handle establishes a new off position with respect to the valve housing, andmeans for detachably mounting said valve housing on said pump and tap assembly.

Abstract
A valved dispenser for use with a pump and tap assembly, for dispensing kegged beer and other beverages alternatively in the manner of a fountain dispenser or in the manner of a hand held dispenser, includes a first handle and portion of a cam actuating arrangement suited to hand held operation, and a second handle used in conjunction with the first handle and another portion of the cam actuating arrangement as well as retaining coupler elements on the pump and tap assembly and valve for effectively converting the dispenser to the fountain type. To reduce foam generation while dispensing, a stem guide is formed to permit fluid passing through the valve to flow around the guide for reduced flow velocity. A threaded valve seat element and push-back stem with ready access to a key pivot pin are included for simplified valve disassembly for cleaning and maintenance. In a preferred embodiment one coupler element comprises the bearing housing portion of the pump which is uniquely suited for such incorporation as part of new pump manufacture as well as for such conversion of existing pump and tap assembly pumps for use in the present invention.

16. A valve having means for effecting on states and an off state with respect to fluid flow, said valve comprising:
-
a housing, a spigot mounted on the housing, means for coupling a tube to the housing for delivery of fluid to the valve, a handle member rotably mounted on the valve for controlling the valve'"'"'s on states by angular displacement of said handle away from a predetermined off position with respect to the valve housing, said means for effecting the valve states includes; a cam having a pivotal axis and a substantially flat bearing surface, a bearing area on the valve housing and means for biasing the cam against said bearing area, and an actuating linkage which is connected to said pivotal axis, which moves with the axis, for controlling the valve states; said handle member is attached to the cam for rotation of the cam by angular displacement of the handle for controlling the valve'"'"'s on states, said off state position is established upon bearing of said flat cam surface against the bearing area on the valve housing, a valve seat element located in said housing through which fluid may enter the valve housing, a valve stem having a head which may sealingly mate with the seat to prevent fluid flow into the valve housing, a portion of the stem passes through the valve housing for engaging with said actuating linkage, means for sealing to prevent leakage around the shaft, situated within the valve housing in close communication with the housing and in sliding communication with the shaft, a stem guide extending internally from the housing, said guide having bearing points in slidable contact with the stem near the head for holding the stem in alignment with the seat, said stem including a stop behind the head for receiving urging force, resilient means disposed between the stem guide and the stem for exerting forces simultaneously against the stem stop and housing for urging the stem head toward the valve seat and, by way of the actuating linkage, drawing and biasing the cam against the valve housing bearing area, said stem guide extending internally from the housing is formed to permit fluid passing through the valve to flow around the guide during its passage on out through the spigot, said valve housing includes an extending portion in intimate sliding contact with the cam for restricting the handle member'"'"'s angular displacement to that of movement in a predetermined plane with respect to the housing, said valve seat element includes a threaded portion, and said tube coupling means for delivery of fluid to the valve, said valve housing includes threads and a stop for securing the valve seat in the housing to a predetermined depth when the valve seat element is screwed into the housing, said valve seat element includes at least two bearing surfaces for receiving torquing forces for installing and removing said element.
