<p>The present invention provides a treadle assembly for use in combination with a rotating frame type trap in which pairs of opposed jaw bars are disposed in adjacent relationship when the trap is cocked and in which the jaw bars are forcibly urged toward each other when the trap is uncocked, comprising base means for resting on a support surface and including portions for defining opposite runs from which animals to be trapped may approach the trap; treadle-lever means comprising a generally plate-like element overlying said base means and normally spaced therabove; fulcrum means between said base and treadle-lever means defining above said base means a pivot axis for said treadle lever means transversely between the portions defining the opposite runs for the animals, said treadle-lever means comprising opposite operating-lever portions for the treadle assembly, said base means having vertically extending abutment means therein extending toward said operating-lever portions for dislodging at least one jaw bar of a cocked trap off the treadle-lever means when the trap is actuated, said treadle-lever means including means for opposed jaw bars of the cocked rotating-frame type trap for retaining the trap jaws in a cocked condition until the vertically-extending abutment means dislodges the one jaw bar off the retaining means when the trap is actuated.</p> |
