Abstract
Abstract The object of the invention is to provide a feeder for livestock which is simple and easy to assemble at the site of use and which is compact for shipment. The feeder 10 includes a center section 42, a drive shaft 106 and drive shaft support 44 and an idler shaft 64 and idler shaft support 40. The center section 42 has a plurality of reversible and identical side panel members 150 and 152 formed from flat pieces of sheet metal. Each side panel member 150 or 152 has a tapered bed support ledge 154 and an endless conveyor chain return run support ledge 158. A spacer bracket assembly 166 with two generally vertical side sections 170 has two side panel members 150 or 152 secured to each side section 170. The drive shaft support 44 is attached to one end of the center section 42 and the idler shaft support 40 is attached to the other end of the center section 42. A tapered bed is secured to the tapered bed support ledges. An endless chain 48 with attached conveyor slats 50 is trained around the drive shaft 106 and the idler shaft 64. Each conveyor slat assembly 186 includes an antifriction wear strip 194. A cover 200 snaps over conveyor cover retaining flanges 164.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
228 words
A tapered bed feeder conveyor including an elongated center section, a tapered bed secured to the center section, an idler shaft rotatably journaled on the idler shaft support, at least one conveyor sprocket secured to the idler shaft, a drive shaft support secured to the other end of the center section, a drive shaft rotatably journaled on the drive shaft support, at least one conveyor sprocket secured to the drive shaft, at least one endless chain trained around the sprockets on the idler shaft and the drive shaft, conveyor slats extending from the endless chain operable to convey material along the upper surface of the tapered bed and a conveyor drive operable to drive the drive shaft characterized by the elongated center section including two reversible and identical side panel members formed from sheet metal with an integral tapered bed support ledge and an integral endless chain return support ledge, each side panel member including upper and lower edges and at least one sloping section intermediate the edges enabling the side panels to nest together while disassembled with one of the side panels turned end for end and corresponding upper and lower edges on adjacent nested panel members being vertically and horizontally offset from each other; and a plurality of spacer bracket assemblies connecting one panel member to the other panel member in a parallel spaced apart relationship.
