Abstract: A spring installation tool for article loading machines is provided to facilitate the application of a biasing spring to sets of guide fingers. Fundamentally, the invention includes an elongated frame member having a tubular portion at a first end thereof for receiving the biasing spring. A rod is provided having a ring at one end which encompasses the tubular portion while being maintained in spring-biased engagement at an opposite end thereof with a second end of the frame member. The rod is operative for reciprocating movement with respect to the frame member to effectuate forcing of the biasing spring from the tubular portion. In use, the tubular portion, bearing a biasing spring, is placed over the end section of a set of guide fingers and the rod is reciprocated to force the spring from the tubular portion into securing and biasing engagement with the fingers.

Abstract: Apparatus for creating optical illusions utilizing a rotating circular disc having alternating transparent and reflective areas according to a predetermined pattern. The reflective area is approximately equal to the transparent area. As the disc rotates at a user's selected speed the user perceives alternating reflected and transmitted images. Thus where the apparatus is positioned between an object and the user the transmitted image of the object is superimposed upon the reflected image of the user and consequently the two images merge to form the desired optical illusion.

Abstract: A vegetation spraying assembly including a support framework mounted on the front of a tractor and movable vertically by hydraulic cylinders. A plurality of arms extend forwardly from the framework to distal ends supporting wedge-shaped guards with spraying nozzles supported rearwardly of the guards and aimed to spray rearwardly in a horizontal pattern. A plurality of collector trays are supported on the framework rearwardly of the spray nozzles.
