and the driving motor is activated in this condition the medial timing disc is pivotably moved relative to the base to adjust the absolute time of deposit of feed in the timing cycle which well determines the particular time of day at which food will be deposited when so adjusted the device then operates automatically to deposit the premeasured quantity of food at the same time during each time interval between the passage of successive reservoirs over the disbursement slot in the medial adjustment disc this periodic timing will be predetermined by the parameters related to the rotary speed of the motor the nature of the gearing linkage between motor and storage disc and the angular position and spacing of reservoirs about that disc all as heretofore well known in the mechanical arts normally however these parameters will be regulated to move successive reservoirs for deposition of food once or twice each twenty four hour period it is to be noted from the foregoing description that any particular number and size of individual storage reservoirs may be provided within the teachings of my invention and though the particular device shown is adapted for use in feeding fish the same principals would apply in feeding various other small animals or in fact even larger animals if the structure be of appropriate size it is further to be noted that animals may be fed varying amounts of feed by appropriately varying food amounts in the successive food reservoirs and that.
