Abstract
ABSTRACT OF THE DISCLOSURE
An animal trap which includes a base, a pair of jaws, and a pair of torsion springs, all made of bent wires and characterized by the base, one jaw and the springs being integrally made by having the one jaw acting on the other jaw for equal forceful closing of both jaws, and by having a latch and a resilient tripper wire adjustably connected to the latch for non-actuation of the latter by small animals in relation to adjustment of the tripper wire relative to the latch. This animal trap further comprises the base and the one jaw being formed by the opposite ends of the torsion springs, the other jaw having lateral pro-jections with the one jaw abutting against these projections to bias the other jaw toward an animal trapping position, each jaw having a crossbar outward of a central aperture, a pair of latch members pivoted to the crossbars respectively and releasably engaging each other, and the resilient tripper wire being adjustably connected to one of the latch members.

The outer end portlon 7 of each outwardly pro~ecting leg 2 is bent upward relative to the remsinder Or the base and rorms an eye loop at the very end. A second rectangular ~aw, cr frame, is pivotally eDgaged in the eye loops defined by the outer end portions 7. This second rectan-gular ~aw includes a pair of lsterall~r spaced-apsrt arms 8 snd a crossbsr 9 integrslly formed ~ a bent wire or rod and definiDg a centrsl aperture.
The free end 10 of esch latersl srm 8 pro~ects lateraUy outwardly~ is pivotslly ongsged in the corresponding eye loop; and cooperatively defines the pivot a~ciJ of tho second ~aw. ~ach lateral arm 8 is also formed with a laterally e~tendiDg portion 11 intermediate the ends thereof to form an abutment for the corresponding lateral ~ido of the first Jaw.
A latch operati~ely connects the two ~aws in open and cocked ~osltion, as shown in Figures 2 to 5. This latch includes an arm 12 pivoted on the cros~bar 9 of the 8econd ;~AW and notched at 13 at the outer free end to form a hook. The latch also includes a clamp 14 engaged over the crossbar 6 of the first ~aw and formed with a notcb 15 extending lower on one side of this crossbar than on the other.
L~n inverted V-shape tripper device, or wire 16, has an in~er-mediate laterally bont portlon 15' engaged in the clamp 14 and pointiDg into the lowest end of the notch 15. The oppoqite ends of the triDper ~ire down~rardly pro~ect on the opposite sides of the clamp 14 and may be ad~ust-ab~ ~pread apart to vary tho pivotal play o~ ths tripper wire relative to the clarnp 14. Tl~ t is, if the tripper wire 16 is spread wider, tho bent portlon thereof ln the clamp 14 uses less 2~pace in the latter and i8 allowed more pirotal play back and ~orth longitudinally o~ the . .
. . .
l~J4~ 6 p before pivoting of the clamp itself. Thus, the small animals may pivot the tripper wire 16 without pivoting of the clamp 1~ around the : crossbar 6. It will be readily understood that pivoting of the clamp 14 one way or the other lifts and releases the hook, or lever 12, causing the springs 1 to close the first jaw and the second jaw, the latter by action of the sides 3 on the shoulders 11.
It will be noted thst the sensitivity of the tripper device can be increased or decreased by bending more or less the intermediate portion 15~ with consequent decrease or increase of the friction between portion 15l and olamp 14.
A holddown wire 17 removably hooks to one of the torsion springs 1 to be used for opening of the trap, as shown in Fi~ure 7. The trap may thus be firmly and saf dy held by enga~ement of one foot on the holddown wire 17 and the other foot ovcr one end portion 7. Both hands may thus safely be used to raise the two jaws to a cocked position - and to engage the two latch members 12 and 14 with each other.
It will be noted that the two jaws can be raised beyond the cocked position of ~i~ure 4 to a position wherein abutments 11 will engage a portion of sides further away from springs 1 so that the two jaws can re~ain in open position, even when lever 12 is released. Thus, the trapper can, with safety, reach between the open jaws, for instance~
to remove trapped animal~. The trap is also safe because it is never locked in closed position, contrary to conventional traps using a pair of sprins-loaded eyes embracln6 and sliding along the sides o~ the jaws.
Therefore, even if a tr~pper's limb is accidentally cau~ht between the jaws, the trapper can still open the jaws to release himself.
The cocked position of the jaws tsee Fig. 4) is automatic-ally reached when notch 13 of arm 12 fits notch 15 of clamp 14 and around wire 6. In this cocked position, a straight imaginary line joining pivot point 10 and abutment 11 makes an an~le slightly ~reater than 90 ~ - 5 -... - : .. . .

1- An animal trap comprising a pair of laterally spaced-apart torsion springs, each having a pair of outwardly projecting legs, a base fixedly secured to one leg of each of said torsion springs, one jaw fixedly secured to the other leg of each of said torsion springs and pivotable thereby toward said base, another jaw pivoted to the base at a distance from said torsion springs about an axis substantially parallel to the axis of said one jaw, said other jaw having at least one abutment operatively extending in the pivotal path of said one jaw and engageable by the latter upon pivotal movement thereof, a latch operatively engaging and holding said one jaw in predetermined cocked and angular position relative to said other jaw, and a tripper device connected to said latch and engageable by an animal for tripping of said latch and release of said jaws, thereby allowing spring biased pivoting of the jaws toward an animal-trapping position.
2- An animal trap as defined in claim 1, wherein each of said base and said one jaw includes a frame having laterally spaced-apart opposite side portions integrally formed by the legs of the torsion springs.
3- An animal trap as defined in claim 2, wherein said other jaw includes a frame forming laterally spaced-apart opposite side portions, each having a lateral projection forming two said abutments.
4_ An animal trap as defined in claim 3, wherein the laterally spaced-apart opposite side portions of the other jaw are made of rigid wires, each bent to form a laterally extending portion constituting the corresponding abutment.
5- An animal trap as defined in claim 1, wherein each of said jaws includes a rectangular frame defining a central aperture and having a crossbar transversely extending relative to said base and outwardly of the central aperture, said latch includes a pair of latch members pivotally mounted one on each crossbar, and releasably engaging each other, and said tripper device is secured to one of said latch members and pivotable therewith for tripping of the latch members.
6- An animal trap as defined in claim 5, wherein said tripper device is an inverted V-shape tripper wire extending toward the central aperture, and said one latch member is a U-shape clamp engaged over the corresponding crossbar and clamped to the central portion of the tripper wire and holding the latter for pivotal displacement therewith.
