Abstract

Abstract An improved actuator for a rotating frame animal trap, wherein the ring at one end of the coil spring is provided with an opening through which the adjacent ends of the frame, about which the ring is normally disposed, can pass when the actuator is swivelled around the frame to a predetermined position, so that the actuator bias is then removed from the trap jaws. A stop may be associated with the opening in the ring to prevent the frame ends from passing through the opening when the actuator is swivelled in a particular direction. A keeper may be releasably fastened across the ring opening to minimize unwanted disengagement of the actuator. Also a releasable safety clamp may be provided for maintaining the arms of the actuator in an almost fully compressed state.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 296 words
In an animal trap of the type having two similar first and second frames made of round wire stock, each having sides serving as jaws and ends extending therebetween, and which are pivotally connected through adjacent ends for relative rotation between set and closed positions about a common axis, trigger means for releasably maintaining the trap in set position and an actuator made of round wire stock, capable of rapidly and forcefully effecting such rotation upon release of the trigger, having two arms spring biased at one end so that the other ends if unobstructed would move to a distance substantially greater than the length of said frame ends, each arm terminating in a ring respectively adapted to encircle adjacent ends of both frames on opposite sides of said axis: a quick release feature which comprises an opening in one of said rings, the other of said rings being completely closed and encircling said adjacent frame ends, the width of the opening in said one ring being substantially greater than the diameter of the wire stock of the frames, and the position and width of said opening being such that, when the actuator, in sprung condition with its rings encircling adjacent ends of the frames of the trap, is swivelled around the frames of the trap, when closed, to a predetermined position (not normally achieved in either the said set or closed position or while the trap is closing), said adjacent frame ends encircled by said one ring can readily pass through the opening, whereby said adjacent frame ends are thereby disengaged from said one ring, thus permitting said other ends of said actuator arms to move apart freely to said distance and at the same time permitting the pressure closing the jaws to be released.
Claim 2
Dependent Claim 296 words
In an animal trap of the type having two similar first and second frames made of round wire stock, each having sides serving as jaws and ends extending therebetween, and which are pivotally connected through adjacent ends for relative rotation between set and closed positions about a common axis, trigger means for releasably maintaining the trap in set position and an actuator made of round wire stock, capable of rapidly and forcefully effecting such rotation upon release of the trigger, having two arms spring biased at one end so that the other ends if unobstructed would move to a distance substantially greater than the length of said frame ends, each arm terminating in a ring respectively adapted to encircle adjacent ends of both frames on opposite sides of said axis: a quick release feature which comprises an opening in one of said rings, the other of said rings being completely closed and encircling said adjacent frame ends, the width of the opening in said one ring being substantially greater than the diameter of the wire stock of the frames, and the position and width of said opening being such that, when the actuator, in sprung condition with its rings encircling adjacent ends of the frames of the trap, is swivelled around the frames of the trap, when closed, to a predetermined position (not normally achieved in either the said set or closed position or while the trap is closing), said adjacent frame ends encircled by said one ring can readily pass through the opening, whereby said adjacent frame ends are thereby disengaged from said one ring, thus permitting said other ends of said actuator arms to move apart freely to said distance and at the same time permitting the pressure closing the jaws to be released.
Claim 3
Dependent Claim 30 words
An animal trap according to claim 1 wherein said opening is located in a portion of the ring proximate to the spring-biased end of the actuator and the actuator arm.
Claim 4
Dependent Claim 50 words
An animal trap according to claim 2 further comprising a keeper adapted to be fastened for purposeful disengagement across said opening whereby said open ring is closed to prevent said adjacent frame ends disposed within said ring from passing through said opening while said keeper is fastened across said opening.
Claim 5
Dependent Claim 64 words
An animal trap according to claim 3 wherein the frames are of square or rectangular shape and have outwardly projecting ears located at each end of adjacent frame ends disposed within said rings where the rings of the expanded spring would rest when the trap is in closed position, whereby said ring members are prevented from slipping onto either pair of adjacent side members.
Claim 6
Dependent Claim 39 words
An animal trap according to claim 3 wherein said keeper is adapted to be fastened to one arm of the actuator on one side of the opening and to a hook-like lip on the other side of the opening.
Claim 7
Dependent Claim 66 words
An animal trap according to claim 5 wherein said keeper comprises an elongated handle portion and a base portion fixed thereto defining a triangular opening, the base of the triangular opening being remote from the handle of the keeper, and the two corners of the triangular opening remote from the handle being adapted to be fastened about said one arm of the actuator and said lip.
Claim 8
Dependent Claim 28 words
An animal trap according to claim 6 wherein said keeper, when in fastened position across the opening of the ring, maintains the generally circular configuration of the ring.
Claim 9
Dependent Claim 26 words
An animal trap according to claim 7 wherein said triangular opening is in the form of an isosceles triangle having base angles of greater than 60*.
Claim 10
Dependent Claim 15 words
An animal trap according to claim 8 wherein said keeper is chained to said actuator.
Claim 11
Dependent Claim 66 words
An animal trap according to claim 2 wherein a stop is provided on said open actuator ring near the actuator arm where it does not interfere with the normal operation of this ring to prevent passage of the frames through the ring opening and subsequent jamming of the actuator arms against the frame when the actuator is swivelled in a direction away from the ring opening.
Claim 12
Dependent Claim 36 words
An animal trap according to claim 10 wherein said stop consists of a shoulder on said open ring near the actuator arm against which shoulder the trap frames lodge preventing their passing through the ring opening.
Claim 13
Dependent Claim 23 words
An animal trap according to claim 2 wherein one arm of the actuator and a hook-like lip form opposite sides of the opening.
