Abstract: A feeding system for delivering feed to troughs associated with rows of animal confinement cages is disclosed. The system comprises mobile hopper means for carrying a load of feed past troughs associated with each row of animal confinement cages. Delivery means extend from the hoppers; these delivery systems each receive feed from the hopper and deposit the feed in the feed troughs. The delivery sub-systems include a tube extending from a hopper and hopper conveyor toward a distal tube end at the trough. A shoe is attached to the tube at the distal end so as to support that tube distal end at the location spaced above the trough bottom. A grader blade is pivotally attached to the shoe in such a position as to be located behind the tube when the shoe and tube are moving in a forward direction along the trough.

Abstract: A rotating message device having upper and lower plates, a plurality of side panels forming a body with a hollow interior and a drive motor disposed in the hollow interior and connected to a supporting structure by arms extending upwardly through the top plate. At least some of the panels are partially transparent and a light means is disposed in the hollow interior to light up the transparent panels. The panels are replaceably held in vertical position along the sides by posts interconnecting the upper and lower plates and by flexible strips placed in front of the posts, thus permitting the panels to be inserted and removed whenever messages or signs are to be changed.
