The device for fixing the bird comprises a duct 1, made of a transparent material, at the base of which a drive mechanism is placed, supporting a drive disk 2 mounted on a shaft. A reversible electric motor. The guide fingers 4 are fixed on the surface of the drive disk 2, connected along the front of the leads 5 with the P-shaped levers 6, which are hinged at one end on the supports 7 of the base of the box 1, and the other are rigidly connected to the concave plates 8 for fixing head zo and torso birds.

The concave plates 8 have measuring devices 9, as well as an elastic coating 10 installed on the side of the fixed bird.

"JO

The grips of a bird's legs are made in the form of W-shaped spring clips 1i, placed on the surface of the base of the box 1, where also the manure mark Q 12 is fixed.

between the F-shaped arms 6, is rigidly fixed by the concave plates 8 in a certain position. When the drive mechanism is turned on, the reverse disk 2, rotating in the opposite direction, acts on the levers 6 by means of the same guide fingers 4. And the leads 5, pushes the P-shaped levers 6, releasing the bird from fixation. 4 hp f-ly, 3 yl.

The device works as follows.

The examined bird is moved to the box 1, while its legs are inserted into the grooves of the W-shaped spring clips 11, thereby depriving the bird of mobility. At the same time turn on the drive mechanism. At the same time, the disk 2, turning in one direction or the other, by means of the paul 4 and the leads 5 moves the F-shaped levers 6 with the plates 8 bent, which fix the bird's head and torso. Being held in such a way, the bird completely loses its mobility, which allows using measuring devices 9 mounted on concave plates 8 to make appropriate measurements.

exterior I

After the measurement operations are completed, the electric motor is turned on and the F-shaped levers 6 are separated to the sides, at the same time the operator opens the W-shaped spring brackets 11, freeing the bird's legs from fixation. ,

Claims (4)
