Description

Offered. The invention is a variety of devices for killing rats, mice, gophers and other rodents with an electric current. The novelty of the present invention is seen in the consumption of electrical energy only at the time of the communication of the deadly electrical shock with a minimum current voltage. After killing one animal, the device is automatically prepared to kill the next animal trying to reach the bait.

FIG. 1 shows a longitudinal section of the device; FIG. 2 is a section along the AB of FIG. one; FIG. 3, 4, 5, 6 and 7 details of the device device.

The device device is as follows. The four-sided closed cd 1 leading to the bait rises upward at such an angle that an animal killed by electric current must slip out of it due to its gravity. The top board 2 (Figs. 1 and 6) is screwed with four screws and therefore can be easily removed for repair.

In order to kill the animal with an electric current of minimum voltage, the device has a device for douche of the animal touching the animal.

bait, a solution of some highly conductive salt (usually common salt, soda, soap powder, etc.), in which a small amount of soap is dissolved. Due to this, firstly, the transient resistance of the electric current from the skin of the animal is greatly reduced and therefore it can be killed by a low voltage (for rats and mice, it is likely that the PO-120 volt of the home lighting network is sufficient) secondly, not only the contact of the animal with the lower electrode on the board 3 of the stroke is improved, but the sliveriness of the surface of the board 3 also increases.

For this, in the upper part of stroke 1 (Fig. 1, 2 and 7) there is a box 4 of papier-mâché, cardboard, tin covered with asphalt varnish and the like with a partition in the middle (Fig. 2). This box is installed on a stand 6 (FNG. 7) made of wires or galvanized iron strips. which, together with a ladder 6 rigidly bonded with it, on galvanized galvanized wires, can rotate around an axis 5 of thick 6 mm in a galvanized dialectra wire inserted into side vertical boards 7, as

indicated in FIG. 2. The animal bait attaches to the upper part of the ladder 6 under the box itself 4. Therefore, an animal that has fallen on turn 1, striving to bait, will surely grab the front legs of the ladder 6. From the body of the animal ladder 6, and hence the box 4, the solution contained therein, of the above composition, will begin to pour out from the left side of the box 4 into two adjacently installed boxes 8, 8, and of the latter onto the animal.

Each of the boxes (Fig. 2 and 4) consists of two metal (tin-plated) boxes 8 and 8, one above the other, separated from each other by a plank of well-paraffinized or impregnated wood, of pressboard or another insulating material. The two boxes 8 (Fig. 2), isolated from each other, are separated by wires from each phase of the rosette plug 10, and from the box 8, the wires are connected to the upper 11 (Figs. 1 and 5) and lower 12 electrodes. These electrodes 11 and 12 are energized only when the salt solution that is poured from box 4 into box 8 gives them electrical connection to the bottom cord 8. The wall of box 8 facing the inside of the device is made 5-7 mm below the other walls. Therefore, an excess of saline will begin to pour out through this wall onto the animal that has entered the device as soon as the box 8 is filled with the solution to the level of this wall. In addition, since a whole row of small holes are made in the bottom of the bottom box 8, first, the animal gets under this shower from salt solution and, second, the electrical connection between the boxes is destroyed as soon as the solution drops below the end of the box 8 Thanks to such a device, the electrodes 11 and 12 will only be under tension for the short time needed to kill the animal. The device of the upper electrodes 11 can be seen from FIG. five; each of them represents a metal wire bent at a right angle with a loop in a bend angle, by which the electrode is put on the wires connected to each other and to the conductor box 8. The electrodes 11 have a beam or a brush P made of thin copper wires at the downward end, and a counterweight 1G from the wire bent into a spiral on the vertex: the end. Therefore, the animal, climbing along route 1, easily deflects these electrodes. When is a doused animal trying to escape or fall down if killed immediately, hitting between the topmost electrodes 11, going directly from box 8 and ladder 4; electrically connected to the lower electrode, the electrodes 11 will spring and therefore thin 1G wires are thrown into the skin of the animal, ensuring good contact.

The bottom electrode 12 on. the board 3 is arranged in the following way: tin foil is glued to the board 3, the top is pressed by a ladder of metal (tinned iron or copper) wire electrically attached to another box 8. At the same time, the transverse steps of this wire ladder should be deepened into wood so that the dead animal slid down easier. At the moment when the solution is poured out of the inclined box 4, a short circuit between the two boxes 8 cannot be created through it, so the box 4 has a partition in the middle (Fig. 2), due to which two compartments are formed in this box only a hole 14 in the back of the box 4 (Fig. 7), and the lower edge of the compartment is only 2-3 mm below the normal level of the solution in the box 4. Therefore, it is enough for the left end of the box 4 to drop 5-6 mm so that the solutions in the double compart x boxes 4 separated from each other botfly conductive wall.

The height of the normal level of the solution in box 4 is determined by the position of the tubes 15 passing through the cork 16 into the can 17 with the stock of the solution (Fig. 1, 2 and 7). One of these tubes 15 ends directly under the stopper 16, and the other comes almost to the very bottom of the can 17. Therefore, when the can 17, which is full almost to the top, will be tilted and placed on the top plate of the apparatus so that the stopper 16 and the tubes 15 pass through the This board has a round hole dropped into box 4, then the solution will be poured out of box 17 tilted upside down into box 4 only until the holes in the tubes 15 are covered with a solution in box 4. This determines the normal level of the solution in it. The left end (Fig. 7) of box 4 is made longer, but shallower, and the right end is deeper, but shorter, and the whole box 4 is suspended on axis 5 so that when there is a solution in it, then the right end of it is stronger. it stands still in a horizontal position, resting against the bar 18 when the box-4 is tilted and the solution begins to pour over the left side of the box, this iridescent solution layer makes the left end of box 4 more difficult (of course, with the ladder 6 ) and therefore it will remain inclined to the left until the entire solution is poured from it. When the latter happens, a large amount of the right end of box 4 will again bring it to horizontal position by itself, the ends of the tubes 15 are exposed and therefore the solution of the can 17 will refill the box 4 to a normal level.

Such a device of the box 4 provides a constant automatic powering of the device with electrolyte, because the volume of the can 17 can always be chosen so that the device must be charged no more than once a day.

In the lower part of the board 3 there are cross-sections through 19, through which the saline flows into the vessel (baking tray) 20, from which it can be poured back at any time to the can 17. Therefore, in the operation of the apparatus, the consumption of this solution is very small.

The subject matter of the invention.
