Abstract

A power saw guide assembly comprises a base member adapted for mounting on a saw table and having a circular recess in its upper surface. A U-shaped mounting member defined by a plate portion extending between two legs is rotatably and lockably mounted on the base member for rotation about a vertical axis with the plate portion slidably seated against the upper surface of the base member and a cylindrical boss secured to and extending downwardly from the plate portion seated in the circular recess of the base member. An elongated track member has one end thereof disposed intermediate and pivotably secured to the legs of the mounting member for pivotal movement about a horizontal axis; it has a generally U-shaped cross section defined by a web and two legs, the free longitudinal edge of each leg having a longitudinally extending flange projecting inwardly therefrom in spaced parallel relation to the web. An elongated slide member adapted for mounting a power saw thereon is slidably disposed intermediate the track member flanges which are slidably received in longitudinal grooves in opposite vertical side surfaces of the slide member.

Dependent claims

A power saw guide assembly comprising:

a. a base member adapted for mounting on a saw table or the like and having a recess of circular cross section opening in the upper surface thereof;
b. a mounting member having a generally horizontal plate portion slidably seated on the upper surface of said base member;
c. a cylindrical boss having its upper end secured to said plate portion and its lower end portion rotatably seated in said recess of said base member whereby said mounting member is rotatable relative to said base member about a first axis;
d. an elongated track member having a generally U-shaped cross section defined by two spaced vertical legs with a web extending therebetween, the free longitudinal edge of each of said legs having a longitudinally extending flange projecting inwardly therefrom in spaced parallel relation to said web to define a channel therebetween;
e. means pivotably mounting one end of said track member to said mounting member for pivotal movement about an axis perpendicular to said first axis;
and
f. an elongated slide member adapted for mounting a power saw thereon and slidably disposed in said channel, said slide member having a pair of vertical side surfaces each having a longitudinal groove therein in which is slidably received one of said flanges.
