Pressure wire trap for catching gophers and hamsters, device, dimensions, principle of operation, features of normal pressure traps.

For catching gophers and hamsters, a wire trap is made of spring wire 3.3-3.5 mm thick, from which a coil spring (1) with a diameter of 25 mm is wound in two and a half turns. Her short shoulder is used as a pressing lever (2). The semi-oval body of the aircraft (3) is bent from the long shoulder with the upper transverse frame (4) and the pin (5) bent down from it, which is stuck into the ground when installing a trap in front of the hole.

When assembling the airwheel, the pressure lever (2) is inserted into the semi-shaft (3) of the housing, and the pin (5) is pushed through the spring curl. In this case, the frame acquires the necessary rigidity. On the short transverse side of the frame (6), covering the inside of the spring, screw the rod stand (7) of 1.5-2 mm wire for a flag or goose feather, and on the opposite short side of the frame put on a gatehouse (8) in the form of a groove with flattened free end.

The guard on this wire trap in the form of a bracket with a tooth (9) is suspended on the upper longitudinal side (4) of the frame. When guarding, the pressure lever (2) is raised to the upper horizontal position, placed in the groove of the gatehouse, and the free flat end of the gatehouse (8) is hooked on the tooth of the guard (9). Such a system of interaction of the gatehouse with a guard allows you to achieve extremely high sensitivity of the trap.

A wire trap can be triggered by the slightest touch of the footblock, which increases its catchability. However, for airplanes with tricks of lateral deviation, the action is inconsistent due to a series of accidents depending on the type of animal, its growth, mass, and behavior. This deficiency often leads to breaches, to the capture of the beast by the head, trunk, hind legs and even the tail. There are also known cases when the beast was killed and thrown to the side by the force of a pressing lever.

Wire trap with a swinging guard on gophers, device and principle of operation.

In the ground squirrel fishery, a wire trap with a swinging guard was tested (scheme a, a1) The body of this samovol (3) with a frame (4) and a pin (5) is made of a 3.3-3.5 mm spring wire. On the short transverse side of the frame, covering the inside of the spring, a rod stand (7) for a goose pen or flag is screwed from a 1.5-2 mm wire, and a gatehouse (8) is put on the opposite short side of the frame, also in the form of a groove made of strips of thick roofing iron.

Then, a U-shaped swinging guard with a step (9) is put on the pressure lever. When guarding the wagon, the pressure lever (2) with the guard (9) is raised to the upper horizontal position and the end of the pressure lever is put into the groove (8), which is also raised up to the horizontal position, and its free end is placed in the middle of the ledge of the guard.

In this form, a wire trap is installed in a mink gopher. The swinging guard is symmetrical in both directions. The animal disrupts the airplanes at the exit or at the entrance to the hole, rejecting the guard on the side. At the same time, the gatehouse jumps off its ledge and releases the squeezing lever, which clamps the animal by the neck. When tested in the field, such traps crushed animals by the head and neck, less often across the body. The breaches were mainly due to the fact that small young gophers slightly deflected the guard, crawled under it, and the samolov did not work.

Double-sided pressure wire trap with input ring, pressure lever and pedal guard.

Of the pressure traps of double-sided transverse action with an input ring, a pressure lever and a pedal action, the hunter is best known for “keep the thief”. Such a wire trap consists of a three-coil spring, one end of which is bent in the form of an input ring with two ears for hanging a clamping rod of a pressure device and pedal action.

The second end of the spring is used as a pressure lever, which presses the beast to the lower arc of the ring with a clamping rod. The pedal guard is a wire rod pivotally mounted on the eye of the spring. At the end of the axis of attachment, the guard has a lateral bend, which holds the free end of the clamping rod in a guarded position. This Samolov can be used in the hunting of fur animals living in burrows..

Gopher wire traps “Suslik-3” and “Suslik-4”, device, dimensions and principle of operation.

For gopher fishing, two more designs of burrowing wire traps “Suslik-3” and “Suslik-4” were tested. Gopher-3 (scheme g) has wire guards and a guard pedal action. The spring and housing with the pin (1, 3, 4, 5, 6) of this aircraft are similar to previous designs. It differs in that instead of a cranked bend intended for the groove gatehouse, a U-shaped deflection was made in the upper part of the half-shaft (7).

The gatehouse and guard in this airplane are made in the form of two identical wire rods with curled rings at one end on which they are suspended: one on the upper horizontal side of the body, the other on the lower side of the semi-body. To guard the trap, the pressure lever (2) is raised to the upper horizontal position, its end is led into the deflection (7) and, throwing a gatehouse over it, hold it in this position.

The free end of the gatehouse is intercepted by a guard, giving it a horizontal position and resting its free end in the body of the samolov. By catchability, this wire trap is not inferior to previous gophers traps. It is also simple to manufacture, but less convenient for guarding and installing.

All details of the gopher trap “Suslik-4” (diagram in) with a locking device are made of 3–3.5 mm spring wire, and a guard is made of 2.5 mm ordinary wire. The spring (1) is wound in one and a half turns with a diameter of 15 mm. On the shortened spring arm (pressure lever), retreating 30 mm from the end, twist the oval loop (3) for the locking rod.

From the long arm, the springs bend the semi-oval (4), and in its upper part – the cross-member (6) with a ring (7) and a pin (5). A locking lever (8) is hung on the cross-member for the ring, having previously passed its free end through the loop of the pressure lever (2). Then the free ends of both levers are turned on one and the other side of the half shaft (4) and the airplanes are fixed by threading the pin through the spring curl. A curved lever guard is suspended by a spring curl ring.

To guard the lord, the pressure lever is lifted up and picked up by the locking lever, which also works as a gatehouse. The free end of it is placed on the suspension of the base of the guard. Suslik-4 wire trap in gopher fishing trials showed the same catch as the Suslik-3 wire trap, and slightly higher than traps with a swinging guard and lateral deviation.

Features of burrowing pressure wire traps when catching animals.

All these four burrowing burrowing traps in terms of gopher catch are inferior to plate traps No. 0 and No. 00 by 15–20%. The repelling effect of pressure traps, blocking the exit from the hole, was affected. So, in the fishery for gerbils that live in colonies and their burrows have several exits, as a rule, animals did not fall into the crushing traps when leaving the burrow.

Thin-gopher gophers in their burrows with one exit hid in them for two or three days, fearing a cautious squalor guarded by a hole. From the experience of commercial ground squirrel hunters, it is known that larks, chori, hedgehogs, lizards and many other animals fall into the plate traps set at the burrows; they do not fall into the crushing burrows..

Along with the described traps, there are many other designs based on various principles of operation of pressure and alarm devices. All these airplanes are more complicated to manufacture and do not have a high catchability. There is no need to dwell on them.
