Interlock Device for Cutting Equipment
A mechanism for providing automatic cutoff for an out of control cutting
beam or jet is described.
In the figure, a cutting means 2, which may be a beam or jet, is enclosed in a
transparent housing 4. Attached to or embedded within housing 4 are wires or
air passages 6 connected to a machine interlock circuit (not shown) at terminals 8.
Normal machine operation requires continuous current flow through wires or
constant pressure in air passages 6. An out of control jet or beam interrupts
current flow or air pressure, thereby creating an open in the interlock circuit. This
condition causes the automatic shutoff of the machine in a conventional manner.
As an alternative, housing 4, with its attached wires or embedded passages
6, need not surround the cutting means 2, but may instead be located between
the cutting means and the operator hazard.
