Material flow stoppage detector device
First Claim
1. A flow stoppage detector device for a particulate material supply line comprising:
- (a) a housing having;
(1) first and second adjacent upright conduit sections,(2) a pivoted partition means in said housing comprising a first leg member movable to a first position to form a common side wall for said conduit sections and a second leg member arranged in a position to obstruct flow of material in one of said conduit sections when the first leg member is in the first moved position therefor, and(b) switch means on said housing having a switch actuator movable to a first position and a second position, said actuator, in one of the positions therefor, being adjacent the second leg member in the obstructing position therefor,(c) said particulate material, when the flow thereof through said first conduit section is obstructed, overflowing said common side wall into said second conduit section, to move said switch actuator from one position to the other position therefor.

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.

4. A flow stoppage detector device for a particulate material supply line comprising:
(a) a housing having; (1) a partition means pivotally disposed in said housing to divide said housing into; (a) a first conduit means for receiving material from said supply line, and (b) a second conduit means that has an upper portion open to said first conduit means, (2) said partition means having a first leg member and a second leg member extended on an angle from said first member, and being pivotally movable from a first position in which said first leg member forms one of the side walls of said first conduit means and said second leg member blocks said second conduit means, to a second position in which said second conduit means is open to a flow of material therethrough, and (3) switch means associated with said housing and having a switch arm disposed in said second conduit means and being movable from a first position to a second position to actuate said switch means when particulate material flows from said first conduit means into said second conduit means. - View Dependent Claims (5, 6)
