Erickson super straightener

Abstract

This invention consists of a tool and a bending plate that provides a means of straightening woodcutting saw bars otherwise known as saw bars. The saw bars are used in the process of harvesting timber with machinery. The machinery would include Feller Bunchers or any Wood Processing Machine that uses a hydraulic, electric or gas driven wood cutting chain with a steel bar. The Erickson Super Straightener is a tool that consists of 3 main functional parts. There is a rotating head plate with an attached handle and the separate bending plate. In order to use the tool the bending plate must be secured by welding or bolting it to an adequate flat working surface. The best place to secure the bending plate would be on the machine it is intended to be used for. The tool is then used by slipping the ears of the bent saw bar through the stationary bending plate. The bar is then held securely in place by the bending plate. The rotating head of the tool is then slipped over the tip of the saw bar and positioned on the high side of the twist or bend anywhere along the length of the bar. By applying downward pressure to the handle the operator can remove any bend or twist the bar might have. This tool is cost effective and convenient.

1 . I claim that our invention is a two piece saw bar straightening tool that uses leverage and a tool operators own body strength to straighten a bent or twisted saw bar, with this tool consisting of a first piece being a tool handle and an attached rotating tool head that contains a slip through gap to slide a damaged saw bar through and keep it positioned for straightening, and with a second piece being a separate bending plate that is made with a slip through gap that will hold this same saw bar in a secure and desirable position for straightening, with this tool utilizing all post on either side of this separate bending plate that will be used for straightening either of two ears of a saw bar by designing these bending plate posts so that one ear of a saw bar can be slid through a bending plate gap while a other ear remains outside this gap, positioning one ear of a saw bar in this bending plate gap for straightening. This saw bar described would be used by Tree Harvesting Equipment and other Forestry related equipment.
