Abstract

A small animal trap includes a base, a jaw pivotally mounted to the base and biased to close to one end of the base, a latch bar releasably holding the jaw in an open position, and a touch-sensitive trigger mechanism releasably connected to the latch bar. The trap has a bait holder with the flat base having a top surface and a multitude of resiliently flexible fingers extending upwardly therefrom to hold the bait in the interstices therebetween from where the bait can be removed by an animal only in a manner which would significantly disturb the trigger mechanism, thereby springing the trap.

Claims

1. A small animal trap comprising:

(a) a base;

(b) biased jaw means pivotally mounted on the base for snapping from an open position to a closed position to trap the animal;

(c) latching means for latching the jaw means in its open position when the trap is set and releasing the jaw means to close in response to a trigger actuation movement;

(d) touch-sensitive trigger means for responding to small physical movement and vibrations to move the latching means so that the latching means releases the jaw means to close; and

(e) a bait holder mounted to the touch-sensitive trigger means, the bait holder having a flat base with a top surface and a multitude of closely spaced fingers extending upwardly from the top surface to hold bait in the interstices between the fingers, wherein the fingers are arranged in parallel rows in one direction and in parallel columns perpendicular to said one direction.

2. The bait holder specified in claim 1 wherein there are sixteen fingers arranged in four rows and four columns, with four fingers in each row and column.

3. The bait holder specified in claim 1, wherein each finger has a top end which is rounded and all of the fingers are of equal height.

4. The bait holder specified in claim 1 wherein each finger has a top end, and the top ends of the multitude of fingers are beveled downwardly from the centermost fingers of the multitude to the outermost fingers, the tops of the fingers forming a convex outline so that more of the bait embedded between the fingers is exposed.

5. A touch-sensitive trigger mechanism for an animal trap having a base and a latch bar for restraining a spring activated jaw, the trigger bar mechanism including a trigger bar having latching portion near one end of the trigger bar with an opening therein adapted to receive and releasably hold a curved end portion of the latch bar when the trap is set, a bait holder at the other end of the trigger bar having a flat base with a top surface and a multitude of fingers extending upwardly therefrom to hold the bait in the interstices therebetween, and a pivot portion where the trigger bar is pivotally mounted to the trap base so that the latching portion of the trigger bar may receive and hold a curved end portion of the latch bar when the trap is set, and release the latch bar when the trigger bar is disturbed, thereby allowing the spring actuated jaw to snap to a closed position, wherein the fingers are arranged in parallel rows in one direction and in parallel columns perpendicular to said one direction.

6. The trigger mechanism specified in claim 5, wherein there are sixteen fingers arranged in four rows and four columns, with four fingers in each row and column.

7. The trigger mechanism specified in claim 5 wherein each finger has a top end which is rounded and all of the fingers are of equal height.

8. The trigger mechanism specified in claim 5 wherein each finger on the bait holder has a top end and the top ends of the multitude of fingers are beveled downwardly from the centermost fingers of the multitude to the outermost fingers, the top ends of the fingers forming a convex outline so that more of the bait embedded between the fingers is exposed.

9. A small animal trap comprising:

(a) a base which may rest on a horizontal surface;

(b) a cross-pin which at its ends is pivotally mounted to the base by two staples;

(c) a jaw which is connected to the cross-pin at the ends thereof so that the jaw may pivot back and forth between two ends of the base;

(d) a coil spring for actuating said jaw, mounted on the cross-pin, the coil spring having a portion extending therefrom to the base to provide resistance against the turning of the spring, and at least one arm extending also therefrom to engage the jaw and bear against the jaw so that it tends to close to an end of the base;

(e) a latch bar with two ends, having a loop at one end through which the latch bar is pivotally mounted by a staple to an end of the base opposite the end of the base to which the jaw tends to close, and a curved end portion near the opposite end of the latch bar;

(f) a touch-sensitive trigger mechanism including a trigger bar with two ends, a latching portion at one end of the bar with an opening therein adapted to receive and releasably hold the curved end portion of the latch bar when the trap is set;

(g) a bait holder mounted at the other end of the trigger bar, said bait holder having a flat base with a top surface and a multitude of fingers extending therefrom to hold the bait in the interstices therebetween; and

(h) means for pivotally mounting the trigger mechanism to the base such that the latching portion of the trigger bar may receive and hold the curved end portion of the latch bar when the trap is set, and release the latch bar when the trigger bar is disturbed so that the spring actuated jaw snaps to a closed position, wherein the fingers are arranged in parallel rows in one direction and in parallel columns perpendicular to said one direction.

10. The animal trap specified in claim 9 wherein there are sixteen fingers arranged in four rows and four columns, with four fingers in each row and column.

11. The animal trap specified in claim 11 wherein each finger has a top end which is rounded and all of the fingers are of equal height.

12. The animal trap specified in claim 11 wherein each finger on the trigger mechanism bait holder has a top end, and the top ends of the multitude of fingers are beveled downwardly from the centermost fingers of the multitude to the outermost fingers, the tops of the fingers forming a convex outline so that more of the bait embeded between the fingers is exposed.

13. A small animal trap comprising:

(a) a base;

(b) biased jaw means pivotally mounted on the base for snapping from an open position to a closed position to trap the animal;

(c) latching means for latching the jaw means in its open position when the trap is set and releasing the jaw means to close in response to a trigger actuation movement;

(d) touch-sensitive trigger means for responding to small physical movement and vibrations to move the latching means so that the latching means releases the jaw means to close; and

(e) a bait holder mounted to the touch-sensitive trigger means, the bait holder having a flat base with a top surface and a multitude of closely spaced fingers extending upwardly from the top surface to hold bait in the interstices between the fingers, wherein each finger has a top end, and the top ends of the multitude of fingers are beveled downwardly from the centermost fingers of the multitude to the outermost fingers, the tops of the fingers forming a convex outline so that more of the bait embedded between the fingers is exposed.

14. A touch-sensitive trigger mechanism for an animal trap having a base and a latch bar for restraining a spring activated jaw, the trigger bar mechanism including a trigger bar having latching portion near one end of the trigger bar with an opening therein adapted to receive and releasably hold a curved end portion of the latch bar when the trap is set, a bait holder at the other end of the trigger bar having a flat base with a top surface and a multitude of fingers extending upwardly therefrom to hold the bait in the interstices therebetween, and a pivot portion where the trigger bar is pivotally mounted to the trap base so that the latching portion of the trigger bar may receive and hold a curved end portion of the latch bar when the trap is set, and release the latch bar when the trigger bar is disturbed, thereby allowing the spring actuated jaw to snap to a closed position, wherein each finger on the bait holder has a top end and the top ends of the multitude of fingers are beveled downwardly from the centermost fingers of the multitude to the outermost fingers, the top ends of the fingers forming a convex outline so that more of the bait embedded between the fingers is exposed.
