Abstract
An improved adjustable track cover assembly is provided which facilitates adjustable positioning of a track cover over a work blank feed track and which maintains the position established. The track cover assembly includes a cover supporting bracket which is operatively supported by an adjusting screw in threaded engagement therewith. The adjusting screw is supported for selective adjusting rotation relative to the cover bracket. Snubbing means, including spring means and a member in threaded engagement with the adjusting screw, coact with the bracket to impede relative rotation between the bracket and adjusting screw and thereby maintain a fixed positioning of the track cover. Additional spring means, associated with the adjusting screw support, coact with the adjusting screw to maintain a fixed positioning of the adjusting screw.
