Saw guide having pivotal protractor means

A saw guide for controlling the path/direction of travel, with respect to a selected reference on an object such as a board to be cut, of a rotary or jig saw blade during cutting operations, said saw guide being secured to the base plate of a rotary or jig blade type saw and including

• a carriage having upper and lower substantially planar surfaces and defining first and further upturned longitudinal edge portions, an upturned forward edge portion and an upturned rearward edge portion, said first upturned longitudinal edge portion defining a cut away portion proximate said rearward edge portion, said carriage carrying a stop member forward of said cut away position, said carriage further defining an opening for receiving a rotary or jig saw blade therethrough, said carriage opening blade proportioned for registering with at least a portion of an opening in such saw blade base plate upon mounting said carriage thereon, said carriage being provided with a first bracket member mounted proximate said forward edge portion and extending outwardly from said first longitudinal edge portion, and a second bracket member mounted proximate said rearward edge portion and extending outwardly from said first longitudinal edge portion;
• a rod having a first end portion secured to said first bracket and a second end portion secured to said second bracket whereby said rod is disposed a selected distance from and substantially parallel to said first longitudinal edge portion;
• and
• travel control means for controlling the direction of travel of said saw from a reference defined on an object to be cut, said travel control means including a movable sleeve for being slidably received by said rod, said sleeve carrying a spacer member, said travel control means further comprising protractor means rotatably mounted on said spacer member of said movable sleeve, said protractor means including means for adjusting the rotational position of said protractor with respect to a longitudinal axis of said rod, and protractor face plate means which engage said reference from which the direction of travel of said saw is controlled, said protractor face plate means including means to enable sensing of movement of said protractor means with respect to said reference during cutting operations, said cut away portion of said first longitudinal edge portion permitting pivotal movement of said protractor means on said rod form an operating position below said lower surface to a stored position above said upper surface of said carriage.
