<p>ANIMAL TRAP A swingable frame or trap bar component is pivotally mounted by one end thereof to one end of a stationary frame which includes a pair of spaced and parallel side frames extending upwardly from a base. A heavy duty coil spring normally urges the trap bar component to be released or vertical position. A trigger plate pivoted to the base and is held in the set position by a trigger pivotally mounted on a cross bar between the side frames, said trigger overlying the distal end of the trap bar component when the same is placed in the set position parallel to the base and against pressure of the spring. The trigger engages under the trigger plate to hold the trap in the set position. A sloping cross piece on the trap bar component is engaged by the trigger which is slidable across the cross bar enabling a degree of sensitivity to be imported to the release of the trigger by depression of the trigger plate. When released, the trap bar component pivots around a mounting point swinging in an arc between the side frames and traps the animal between the trap bar component and a stop cross bar extending between the side frames substantially above the mounting point of the trap bar component and the spring, which urges it to the release position.</p> |
