A trap with torsion-acting springs is usually equipped with two trapezoidal arcs (Scheme a) made of a 5 mm spring wire (1). The free ends of the arcs are bent inward and laid apart. They are energized pivotally connected by small (2) and large (3) clips made of 2 mm sheet steel.
As a result of this, a twisting moment arises on the shoulders of the arches of the trap, which turns them into torsion spring. When diluting arcs in one plane (180 degrees), they tend to turn in the opposite direction, but this is prevented by protrusions on the clips. As a result, the arcs are fixed in the neutral position (scheme b). This allows you to safely, without much effort, alert the traps with torsion spring and set them in working position..
Trap with torsion spring for catching squirrels, sables and other fur-bearing animals, device, application features, guard.
To guard the trap, the free link of the gatehouse (4) is threaded through the ear of a large clip (patterns b, c), press it to the clip and fixed in this position by the hook of the guard (5). Then, holding the arcs, they are reduced to the formation of an angle between them of about 90 degrees. In this position, the arcs tend to connect, but they are prevented by a guard. In this form, a trap with torsion spring is ready for use..
At the slightest movement of the guard on either side, the hook jumps off the guard, it is twisted out of the lug of the large clip and releases the arcs, which are compressed with an increasing compression force of up to 10 kg. A trap with torsion-acting springs is usually equipped with a nylon cord, with which it is suspended from a tree branch (diagram c). The trap is designed for fishing squirrels, sables and other fur animals.
A trap with torsion spring is universal. It can be suspended on any trees, over the exit from the hole and placed at the hole and on the trail. The advantage of these traps is that the caught animal is not pressed to the tree, but is clamped by the neck with two arcs freely suspended on the knot, which deprives the animal of support and the ability to escape.
Production of a trap with torsion spring, details and dimensions.
In the semi-handicraft production of a trap, its arcs are bent on a template of 5 mm wire. The free ends of the arcs are paired together and put large and small clips on them all the way. Then the arcs with the force are rotated 270 degrees towards each other. As a result, the inner arms of the arcs, bent at an angle, are folded into one plane with the arcs, giving their sides a twisting moment, which turns them into torsion spring.
Details and dimensions of a trap with torsion spring.
After that, the ends of the arcs protruding from the cage bend 89 degrees to the axis of rotation of the arcs and 17 degrees away from the plane of the closed arcs. In factory conditions, arcs should be made using an automatic machine with all bends, deflection angles and hardened. Pressing the arcs into the clips should also be done automatically.
