The trap has a frame to which the swing-arm is mounted. Part of a trip-pan extends perpendicularly from the frame and engages it, being pivotable about the location of its engagement. An elongated release pin engages that part of the trip-pan at a location spaced from the frame, and the frame has as a support tab extending from it with an aperture through which one end of the pin extends. Part of the end extending through the tab engages the swing-arm when the trip-pan is swung toward the swing-arm, but disengages from the swing-arm when the trip-pan is swung away from the swing-arm. | |
