ABSTRACT:
Evaporative coolers, in the past, have used blowers or fans with horizontal axes of rotation, and pumps with vertical axes of rotation, since the pumps were immersed in base tanks and were thereby always primed. Consequently there has been a need for two separate motors, or alternatively, for drive means between the fan motor and the pump drive shaft. This invention relates to a water distribution means which primes a pump, even though it is above the base tank, by providing a suction conduit with an upwardly directed elbow between the pump and the base tank which will drain when the pump stops, but the spreader above the pump contains a well which slowly empties into the pump housing and conduit, the elbow inhibiting any further syphoning of the water from the pump housing into the base tank. Accordingly, the pump may be coupled to the fan for coaxial rotation therewith.
