A trap anchoring stake for anchoring an animal trap in soft or loose soils where in the past excessive stake length has been required to keep the trapped animal from pulling out the stake. The stake has a spring arm connected to the bottom of the stake for outward pivoted movement, and adapted to retain the stake in the ground by lateral pressure on surrounding soil, or by lateral penetration of the top end of the spring arm into the soil, or both. A spring arm latch is provided for connection to a trap tether chain operable to automatically release the latch by movement of a trapped animal, in case the trapper forgets to release the spring arm. An abutment limits outward movement of the spring arm to an acute angle to the stake, and the arm and stake constitute obstruction means which will hang up on brush or the like if the trapped animal succeeds in pulling the stake out of the ground.
A stake device for tethering an animal trap of the leg hold type comprising an elongated stake sharpened at its lower end to facilitate driving it into the ground, an effectively rigid spring retainer arm pivoted at its lower end to the lower end of said stake and spring means urging the retainer arm about its pivot connection to said stake in a direction away from said stake in which said retainer arm and spring means comprises a retainer arm portion having one end formed into a coil spring portion.
A stake device for tethering an animal trap of the leg hold type comprising an elongated stake sharpened at its lower end to facilitate driving it into the ground, an effectively rigid spring retainer arm pivoted at its lower end to the lower end of said stake and spring means urging the retainer arm about its pivot connection to said stake in a direction away from said stake in which said retainer arm and spring means comprises a retainer arm portion having one end formed into a coil spring portion, said coil spring portion comprising several turns, said stake having an opening in which an intermediate portion of said coil spring is received, a short arm extending from one end of the coil spring engaging one side of said stake, the rigid spring retainer arm portion extending from the other end of said coil spring portion and engaging the opposite side of said stake.
A stake device for tethering an animal trap of the leg hold type comprising an elongated stake formed of flat rigid stock, the upper portion of said stake having parallel edges, the lower end of said stake having an enlarged head extending beyond the edges of the upper portion of said stake, said head having a pointed bottom end and a spring receiving opening, an effectively rigid retainer arm having a coil spring portion received in said opening, and an abutment engaging said stake to bias the upper portion of said retainer arm outwardly away from said stake.
