Abstract
Abstract A saw guide adapted for use particularly with a portable motordriven saw of the circular blade type or router which guide is adjustable to align the saw blade in either the rip position or crosscut position or gradients thereof in relation to the wood or material to be sawed in a manner which saves time and labor and assures the accuracy of the predetermined line along which the saw blade is to travel and worktable therefore.

The top of elevated straight line work guide being elevated to the same height as the top of the elevated member so that their top surfaces lie in the same horizontal plane f. A relatively thin horizontally disposed saw guide plate adjustably mounted above and secured to the top surface of the said elevated member g. A series of wingnuts which are screw threaded on a series of complementary vertically disposed bolts which extend up upwardly the peripheral edge of the said worktable from said table h. Three notches in the periphery of one end of the saw guide plate are adapted to snugly receive said complimentary wingnuts i. A cross slot cut in said end of the saw guide plate and adapted to receive the circular saw blade of he portable motordriven saw when sawing in the rip position j. An elongated longitudinally extending member of the saw guide plate having a pair of parallel longitudinally extending slots each adapted to receive the circular saw blade of the portable motor-driven saw when sawing in the crosscut position k. An elongated longitudinally extending center slot extending between and parallel to the pair of saw blade slots which receive the circular saw blade for crosscutting said center slot adapted to receive a router, and l. A countersunk bolt vertically disposed in said center slot and adapted to adjustably fix the elongated longitudinally extending member of the saw guide plate in horizontal operative position.

Claim 3
Dependent Claim
61 words
A saw guide for portable motor-driven saws of the circular blade type and a horizontally disposed worktable therefore, as described in claim 1, wherein said horizontally disposed worktable (a) is round in shape, said elevated straight line work guide (c) is located about one-third of the distance from the center of the round worktable to the outer periphery of said table.
Claim 4
Dependent Claim
42 words
A saw guide for portable motor-driven saws of the circular blade type and a horizontally disposed worktable therefor, as described in claim 1, wherein the horizontally disposed worksurface covering the top of said worktable is disposable and is easily removable and replaceable.
Claim 5
Dependent Claim
44 words
A saw guide for portable motor-driven saws of the circular blade type and a horizontally disposed worktable therefore, as described in claim 1, wherein the elevated straight line guide fixed to the top of the worksurface is disposable and is easily removable and replaceable.
Claim 6
Dependent Claim
222 words
A saw guide for portable motor-driven saws of the circular blade type and a horizontally disposed worktable therefore, as described in claim 1, wherein the relatively thin horizontally disposed saw guide plate, which is adjustably mounted above and secured to the top surface of the elevated shaped member, has indicator length markings imposed on the top surface of said saw guide plate along the pair of parallel elongated longitudinally extending slots which are adapted to receive the circular saw blade when sawing in the crosscut position, additional indicator markings in the arcuate form of a protractor are imposed on the top surface of said saw guide plate adjacent the outer peripheral edge of that end of the saw guide plate in which the cross slot is cut which is adapted to receive the saw blade when sawing in the rip position, said additional indicator markings in the arcuate form of a protractor shall indicate and are extending at least from 0* to 90* and additional indicator length markings are imposed on the top surface of said saw guide plate along the elongated longitudinally extending bevel edged center slot, which extends between and is parallel to the pair of parallel elongated longitudinally extending saw blade slots which receive the circular saw blade for crosscutting, said center slot being adapted to receive a router.
Claim 7
Dependent Claim
183 words
A saw guide for portable motor-driven saws of the circular blade type and a horizontally disposed worktable therefore, as described in claim 1, which includes a pair of longitudinally extending adjustable parallel elongated raised side guide elements for the portable saw, one of said guide elements is disposed along each outer most edge of the elongated longitudinally extending portion of the saw guide plate and the top surface of each of said raised side guide elements lies in the same horizontal plane, the top surface of the elongated longitudinally extending portion of the saw guide lies in a lower horizontal plane than that of said side guide elements, the side guide elements are adjustably fixed to the saw guide plate by a series of screws which pass through a series of slots which extend at right angles to the sides of said saw guide plate, said screws are adapted to be loosened to permit movement of said raised side guide elements closer together or farther apart to accommodate the width of the saw base and then tightened to fix them in operative position.
