Claim 1

A feeding device for animal foodstuffs permitting adjustment of the feed level, of the type comprising a containing plate (1) provided on the periphery thereof with a metal grating or cage (2) fastened to an annulus (3) disposed in coaxial relation externally to a cylindrical upright distributor (4) vertically sliding within the annulus (3), between two positions of maximum and minimum distance from the plate (1) respectively, connected at the upper part thereof to a feed-carrying horizontal tubular duct (5) supported by ropes (6), said distributor (4) causing the discharge of feed (7) into the containing plate 1, the feed level in the plate (1) depending on the distance of the distributor (4) from the plate (1), characterized in that said distributor (4) is moved close to the containing plate (1) by lowering the horizontal tubular duct (5) and has a number of rectilinear recesses (8) disposed vertically on its outer surface, within each of said recesses being accommodated a flat spring (9) fastened to the lower base of the recess (8) and having the upper free end thereof substantially folded according to a C-shaped configuration so as to form a housing (10) within which one of the teeth (11) located on the inner part of the annulus (3) can be snap-fitted, when said distributor (4) reaches said position of minimum distance from the containing plate (1) by effect of the lowering of the horinzontal tubular duct (5).
