ABSTRACT:
A flow stoppage detector device for a particulate material supply line includes a housing that has a pivoted partition member for dividing the housing into first and second adjacent upright conduit sections. The partition member has a pair of leg members and is pivotally disposed in the housing for movement to a first position in which a first leg member forms a common wall for the conduit sections and the second leg member an obstruction to a material flow through the second conduit section. A switch means on the housing has a switch actuator extended into the second conduit section for movement from a first position to a second position in response to an overflow of material over the common wall from the first conduit section into the second conduit section.
