Abstract
Abstract A sanitary water barrel for use on construction job sites and the like. This system employs a substantially standard barrel that has been modified to accept a replaceable plastic liner. The exterior of the water barrel near the upper end thereof is provided with radially extending hook members to engage with apertures placed near the upper periphery of a replaceable liner. The liner is provided with an integral spout which is passed through an opening in the side wall of the barrel. A weight- and spring-biased closure mechanism normally bears against the spout of the liner as it leaves the barrel causing the closing of the spout and therefore prevents water leakage therefrom. Water is caused to flow by raising a lever on the valve when desired. These special liners can be fabricated in a roll type fashion similar to garbage bags with perforated tear lines provided to separate each individual liner unit.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
223 words
A sanitary drinking water system for construction sites and the like, which comprises: a barrel having an open top end and a closed bottom end and a cylindrical wall defining a cylindrical cavity, said barrel being provided with an opening through said wall adjacent said closed end, said opening defining an extended surface; a removable lid for said open end of said barrel; a plurality of hooks projecting outwardly from said barrel proximate said open end; a replaceable flexible liner disposed within said cavity, said liner having a closed end disposed adjacent said closed end of said barrel and an open end extending from said open end of said barrel, said open end of said liner being provided with reinforced apertures releasably engaged with said hooks; a spout attached to and communicating with said liner disposed adjacent said closed end of said liner and disposed within said opening in said wall of said barrel; and a pinch valve mounted on the external surface of said barrel proximate said opening for normally closing said spout against any flow from said liner, said valve including a lever pivoted from said barrel wall, said lever carrying a cylindrical cut off bar to deform said spout against said extended surface upon action of gravity, and for permitting flow from said liner upon upward movement of said lever.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
51 words
The system of claim 1 wherein said lever of said valve is pivotally connected to a transverse rotatable shaft mounted within brackets attached to said barrel, and further comprises a tension spring surrounding said shaft and attached between said brackets and said lever to bias said valve in the closed position.
Claim 4
Dependent Claim
15 words
The system of claim 1 wherein said spout is provided with a removable closed tip.
