  • Patent number: 4437435
    Abstract: A feeder to provide measured quantities of food at predetermined time intervals for animal feeding. A cylindrical base supports an annular fine timing disc for pivotable motion relative thereto and a circular storage disc, having plural food reservoirs radially spaced about its periphery, immediately thereabove. Each food reservoir is provided with valve structure in its lowermost part that opens by gravity action to sequentially discharge the contents in channels defined through the fine timing disc and the base. Driving mechanism is provided to rotate the storage disc relative to the base member to determine the period between successive good discharges and pivotable motion of the fine timing disc regulates the time of discharge within a period.
