Patent ID: 8276744

Claim:
A method for adjusting a skillet conveyor drive having a motor-driven drive wheel pressing against a skillet and mounted on an adjustable mounting mechanism including a threaded adjusting rod that is biased toward the skillet by a spring mechanism reacting against a fixed support and wherein the compression of the spring is adjusted by rotating an adjusting nut to obtain a pounds of force by which the drive wheel is forced against the skillet to obtain optimal operation of the skillet conveyor, said method comprising: providing an adjustment tool including a tubular housing, legs that support the tubular housing against the fixed support, a piston within the tubular housing and threadedly engaging the adjusting rod of the adjustable mounting mechanism, a threaded stem attached to the piston, a hex nut that is tightened to pull on threaded stem and thereby pull on the adjusting rod of the adjustable mounting mechanism, and a load cell that is interposed between the hex nut and the tubular housing to measure the force that is pulling on the adjusting rod; pulling on the adjusting rod via the adjusting tool to compress the spring mechanism just enough to move the drive wheel away from engagement with the skillet; measuring the pounds of force that was needed to pull the adjusting rod to move the drive wheel away from engagement with the skillet by reading the load cell; referring to a look up table that correlates a measured pounds of force at the condition in which the drive wheel is pulled away from engagement to the corresponding pounds of force that will be applied to the skillet when that compressive force is subsequently released by relieving the pulling on the adjusting rod by the adjusting tool to again let the drive wheel engage the skillet; and adjusting the adjusting nut as needed to adjust the measured pounds of force to that level which when the pulling of the adjusting rod is released will apply the drive wheel to the skillet at the pounds of force by which the drive wheel should be forced against the skillet to obtain optimal operation of the skillet conveyor.
