Abstract
An adjustable product guide assembly for a product saw device includes a product guide plate mounted to a first bracket which is slidable on a bar; a handle mounted on top of a second bracket in an ergonomic location, the handle being connected to a shaft and which rotates a first worm gear pinned to the shaft; a second worm gear which is turned by the first worm gear, the second worm gear which is pinned to a pinion gear; a gear rack on the bar, the gear rack having gear rack teeth which are engaged with the pinion gear; a biasing member disposed between the second bracket that houses the first worm gear and the second worm gear and the first bracket; wherein when the handle is pressed down, in a gear releasing mechanism, the second bracket pivots and compresses the biasing member such that the gear rack teeth disengage from the pinion gear via the first worm gear and the second worm gear, and the product guide plate can be moved along the gear rack teeth of the bar. The gears are sized so that one revolution of the handle turns the worm gear by 36 degrees, which causes the pinion gear to displace 0.2 inches of linear motion. This 10:1 ratio of the turning handle and the turning pinion gear provides the ability to make small adjustments to the position of the product guide plate.
