Abstract: Haybox for feeding horses, provided at the upper part with a cover (3) in the form of a rack with transverse bars (4) and provided at the base with a loose, spring-loaded bottom (8). This bottom can move along guide bars (10) running through perforations in the bottom, which are attached to supporting plates (12) fixed to side walls (2a) and (2b). Around the bars (10) pressure springs (11) are arranged which will press the bottom (8) in an empty condition of the box against the rack. The bottom may be made tiltable by means of a body spherical at the top (13) which abuts bottom (8), the dimension of the perforations (9) being larger than the diameter of the bars (10). The box may contain 2 or 4 pressure springs and be fixed to the wall inclined with respect to the horizontal.
