ABSTRACT:
Disclosed is a two cylinder water well pumping system which uses the wind as a primary driving force with an alternate electric motor drive for use when the wind force is not adequate. The wind drives a square wheel turbine which in turn drives a swash plate which provides a cam surface which then drives a semaphore assembly directly or indirectly connected to sucker cables in turn connected to two pistons carried, respectively, in two cylinder sleeves. The inclined angle of the swash plate alternately drives the pistons to pump water from a well into a storage tank also serving as a mainmast supporting said turbine. In an alterenative embodiment, an electric motor is connected to drive an osillatable bar on a mechancial relay. The oscillatable bar is connected by cables to the semaphore assembly, and may be disconnected from the semaphore assembly by a solenoid. In this embodiment, the sucker cables are connected to the rockable bar in the mechanical relay rather than to the semaphore assembly.
