Abstract
Abstract A feeder pan assembly is provided for use with poultry and the like. A hood includes a shell which extends into a pan to define an annular feeding area accessible to the poultry. A hood-pan interconnector includes a number of supports which are curved and inclined to slide over a corresponding number of ramps formed upon the shell. When the hood and interconnectors are relatively rotated, the interconnector supports slide over the ramps to raise or lower the pan. This pan position readjustment increases or decreases the amount of feed flowing into the feeder pan assembly feeding area.

A feeder for poultry and the like, comprising pan means having an annular undercut lip portion and a pan bottom, hood means including feeder tube means adapted to receive feed from a source and direct it toward the pan means and shell means connected to the feeder tube means and extending to follow the contour of the pan means lip, and locatable at least partly within the pan means but spaced apart from the pan means lip to define an annular feeding area accessible to the poultry, and also spaced apart from the pan bottom to define with the bottom a gate through which the feed must pass when traveling from the feeder tube to the annular feeding area, three inclined ramp members each unitarily formed with and projecting from the shell means, and an interconnector means including three strut members each adapted to extend down the shell means outer contours, across the interior contours of the pan, and thence upwardly into engagement with the pan means lip, and three angularly extended and inclined supports, each support being curved and inclined to lie upon the shell means ramp member with a line contact and secured to two adjacent struts at respective outer strut edges, and being vertically separated from both adjacent supports, whereby rotation of the interconnector means relative to the hood means causes the interconnector supports to slide along the corresponding shell ramps so as to raise or lower the pan means relative to the hood means and consequently to open or close the feed gate, each ramp being defined by an outer edge, and two only of the three outer ramp edges being formed to define a plurality of angularly and regularly spaced apart detents, each detent being sized and disposed to accommodate a strut whereby to inhibit movement of the strut past the detent and corresponding movement of the support along the ramp and consequent vertical movement of the pan relative to the hood and to permit said movement when the two interconnector struts are simultaneously moved out of engagement with the detents.
