Filed:

Oct 9, 1987

Appl. No.:

7/107263

Inventors:

Michael A. Bowman - Sheffield IL
Larry J. Goldbeck - Camanche IA
Richard P. Stahura - Aspen CO
Mark N. Stern - Kewanee IL

Assignee:

Martin Engineering Co. - Neponset IL

International Classification:

B65G 4500

US Classification:

198499

Abstract:

A tensioning arrangement is provided to position belt cleaner blades relative to conveyor belt, which arrangement includes an inflatable bladder which acts to move a pivotally mounted crank, which, in turn, moves a support shaft, which carries the cleaner blades. Pressurization of the bladder causes it to expand thereby engaging the arm which moves the support shaft to a position at which the cleaner blades engage the belt to be cleaned.

International Classification:

B65G 1560

US Classification:

198841

Abstract:

A conveyor belt support mechanism comprising a plurality of slider bars, each having multiple low friction wear surfaces with one wear surface in sliding engagement with the conveyor belt and an adjustment mechanism to compensate for wear to said wear surface by moving the slide bar closer to the conveyor belt as the wear surface wears, and a vertical support system for positioning said slider bars. When loads such as impact loads are placed on the conveyor belt, the slider bars support the conveyor belt and prevent the belt from sagging and stretching. As one wear surface of a slider bar becomes worn past an acceptable limit, the slider bar may be removed and repositioned so that a new wear surface engages the conveyor belt.
