Abstract From the Canadian patent

An animal feeder of the type in which a feed hopper discharges feed downwardly onto a shelf which intercepts the feed so that it does not drop directly to a trough under the hopper and shelf but requires action by the animal to brush the feed off the shelf. In conjunction with the above a water supply line runs, closely beneath the shelf and has at least one fitting or nipple directed laterally outwardly over the trough from which nipple the animal may drink directly. The nipple is of the type minimizing discharge of water directly into the trough. The shelf is so fashioned as to substantially prevent the animal from eating feed directly from the shelf.
