Abstract

The device shown in the figure consists of two parts molded from plastic material, such as polycarbonate, which performs the functions of a handle (or knob), spring-loaded ratchet/detent combination and a numbered dial and pointer. Traditionally, these functions are performed by more parts which are at the same time more expensive to fabricate and assemble.

Forms Thickness Adjusting Device

The device shown in the figure consists of two parts molded from plastic material, such as polycarbonate, which performs the functions of a handle (or knob), spring-loaded ratchet/detent combination and a numbered dial and pointer. Traditionally, these functions are performed by more parts which are at the same time more expensive to fabricate and assemble.

The device in the figure is utilized as a forms feed thickness adjustment by combining the two parts as shown and held by the set screw. As the handle is rotated, the detent tooth on one part snaps from one ratchet tooth to the next on the mating part with an audible click sound and provides a good positive feel of the snap. At the same time, the pointer on one part indicates selected settings shown on the other part. The settings may be included in the molding process or separately added at a later time.
