Abstract
An enhancement for use with automatically cycled saw systems that provides an operator access to two-hand anti-tie down buttons and other machine control functions while manually crowding the material to be cut against the saw's fence. The enhancement includes anti-tie down buttons to prevent a cutting cycle unless both buttons are depressed within preset time limit of each other.
Claims9
A saw having a circular cutting blade turned by a motor and a horizontal table having a slot through which a part of said circular cutting blade may pass, said table saw comprising:
- a blade guard positioned above the table;
- a pair of rails running parallel to both said cutting table and one another;
- a pair of handles slidably affixed to said rails, at least one of said handles including a point of contact to secure a work piece during a cutting cycle, whereby said handles further comprise a pair of mechanical arms operatively connected to said handles so as to crowd a work piece to be cut against a back fence during operation of said table saw;
- an anti-tie down button located on each of said handles;
- a logic circuit integrating said anti-tie down buttons and said circular cutting blade for engaging the cutting cycle;
- said logic circuit preventing said cutting cycle from being engaged unless both anti-tie down buttons are depressed within a preset time limit of each other.

A method of using a saw comprising the steps of:
- providing a saw having a circular cutting blade turned by a motor and a horizontal table having a slot through which a part of said circular cutting blade may pass, said saw including:
- a blade guard positioned above the table;
- a pair of rails running parallel to both said cutting table and one another;
- a pair of handles slidably affixed to said rails, at least one of said handles including a point of contact to secure work piece during a cutting cycle:
- an anti-tie down button located on each of said handles;
- a logic circuit integrating said anti-tie down buttons and said circular cutting blade for engaging the cutting cycle;
- said logic circuit preventing said cutting cycle from being engaged unless both anti-tie down buttons are depressed within a preset time limit of each other;
- loading a work piece onto the table;
- sliding said handles along said guard, thereby causing mechanical arms to crowd said work piece against a back fence;
- depressing both of said anti-tie down buttons within to preset time, thus engaging a cutting cycle to cause said blade to cut said work piece.
