Cycle vacuum sampler device

Claim 1

An automatic water sample collecting device comprising in combination, a portable housing, a self-contained battery supply carried within said housing for the remote operation thereof, a vacuum pump carried within said housing providing a vacuum means for creating a differential in pressure in order to cause water to be drawn into a water tank carried within said housing, said water tank providing means for water to be held, a timer carried within said housing, a flexible tube in conjunction with a rod extending from said timer comprising a valve, and a relay also carried within said housing providing for the automatic shutoff of said device, switch means carried by said device providing for the operation of said vacuum pump, said vacuum pump having line means connected to said water tank, said vacuum pump serving to create said differential in pressure in order that water may enter said flexible tube which extends to said water tank, said timer having a preset cycle causing said rod extending from said timer to depress said flexible plastic tube forming said valve means within a second tube extending into said water tank, said second tube forming a drain means when said valve is opened after each cycle of operation and water entering said water tank reaching a predetermined level governed by the adjustment of an electrode within said water tank, said electrode causing said relay to close, thus shutting off vacuum operation of said vacuum pump automatically.
