Abstract

Abstract A drum filling overflow cut-off device for stopping the overflow in the filling of drums with a liquid fed thereto by a nozzle inserted in a fillhole in the drum. A splash collar position above the fillhole and moveable as a result of liquid splashing therefrom actuates a switch due to a change in position of the splash collar, the switch actuation resulting in termination of the flow into the drum.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 119 words
A device for controlling drum filling wherein a liquid is pumped into a drum through a nozzle inserted in a fillhole in the drum with an annular space defined between the nozzle and the fillhole comprising a. a drum filling power circuit, b. a disc positioned in a horizontal plane above the annular space and upwardly moveable in response to liquid leaving the drum through the annular space, c. a vertically positioned and normally closed electrical toggle switch in the power circuit which breaks the circuit when in the open position which switch is connected to the disc and is actuated to an open position by predetermined upward movement of the disc out of its previously horizontal plane position.
Claim 2
Independent Claim 119 words
A device for controlling drum filling wherein a liquid is pumped into a drum through a nozzle inserted in a fillhole in the drum with an annular space defined between the nozzle and the fillhole comprising a. a drum filling power circuit, b. a disc positioned in a horizontal plane above the annular space and upwardly moveable in response to liquid leaving the drum through the annular space, c. a vertically positioned and normally closed electrical toggle switch in the power circuit which breaks the circuit when in the open position which switch is connected to the disc and is actuated to an open position by predetermined upward movement of the disc out of its previously horizontal plane position.
Claim 3
Dependent Claim 45 words
The device of claim 1 wherein the disc surrounds the nozzle above the annular space and is fixedly mounted to a disc hub attached to the switch, whereby upward movement of the disc is transmitted to the hub actuating the switch to an open position.
Claim 4
Dependent Claim 32 words
The device of claim 1 wherein a movement of the disc which results in a movement of the switch of at least 8* from vertical results in actuation to an open position.
Claim 5
Dependent Claim 14 words
The device of claim 1 wherein the switch is a random motion actuator type.
