Fluid supply and dispensing apparatus

A fluid supply and dispensing means for use in combination with an auxilliary supply of fluid, comprising:

• a. means for dispensing fluid, said dispensing means including means for carrying a working supply of fluid at a working surface level;
• b. means for replenishing said working supply of fluid, said replenishing means connected in fluid flow communication with said dispensing means, said replenishing means including means for carrying a replenishing supply of fluid at a surface level establishing said working surface level, said replenishing means adapted to have removably mounted thereon said auxilliary supply of fluid;
• and
• c. said replenishing means including a fluid displacement member, said replenishing means including spring means for normally urging said fluid displacement member upwardly, said fluid displacement member adapted to be urged downwardly against the urging of said spring means by said auxilliary fluid supply means when said auxilliary fluid supply means is mounted on said replenishing means, the lowered fluid displacement member being immersed in said replenishing fluid supply when said auxilliary fluid supply is mounted on said replenishing means, said surface level of said replenishing fluid supply and thus said working surface level of said working fluid supply being established when said fluid displacement member is immersed in said replenishing fluid supply, and said spring means urging said displacement member at least partially out of said replenishing fluid supply when said auxilliary fluid supply is removed from said replenishing means, whereby the fluid surface level of said replenishing fluid supply and thus the working surface level of said working fluid supply is lowered.
