BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The field of invention relates to saw guide apparatus, and more 
particularly pertains to a new and improved saw guide apparatus wherein 
the same is arranged for orthogonally orienting a saw blade relative to an 
elongate workpiece for cross-cutting of the wood workpiece. 
2. Description of the Prior Art 
Saw guide apparatus of various types have been utilized in the prior art. 
Particularly in rip sawing of wood workpieces, a guide structure is 
arranged typically in a parallel relationship relative to a saw blade. The 
instant organization provides for a slidably mounted saw guide arranged 
for properly orienting a saw member in a ripping procedure relative to the

structure, wherein an end of a rule member serves as an abutment for a 
straight edge for use as a guide for a saw. 
U.S. Pat. No. 4,811,643 to Krieger sets forth a guide for a saw member, 
wherein the guide is arranged in abutment against an edge surface of a 
wooden workpiece to orient a saw that travels relative to the abutment 
member. 
U.S. Pat. No. 4,509,398 to Mason sets forth a further example of a cutter 
structure utilizing a plate to arranged a flange relative to a plate 
structure to provide ease of repetitive cutting of block members. 
As such, it may be appreciated that there continues to be a need for a new 
and improved saw guide apparatus as set forth by the instant invention 
which addresses both the problems of ease of use as well as effectiveness 
in construction in properly orienting a saw guide for ripping of a 
workpiece in a wood cutting event and in this respect, the present

DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIGS. 1 to 7 
thereof, a new and improved saw guide apparatus embodying the principles 
and concepts of the present invention and generally designated by the 
reference numeral 10 will be described. 
More specifically, the saw guide apparatus 10 of the instant invention 
essentially comprises a saw plate member 11 defining a planar bottom 
surface, with a forward edge 11a and a rear edge 11b. The forward edge 11a 
includes a saw indicator guide arrow 21 projecting orthogonally relative 
to the forward edge 11a, with the arrow in alignment with an associated 
rotary saw 15 projecting through the plate member 11. The rotary saw 15 is 
mounted within a saw housing and drive 12 that includes a rear handle 13 
and a forward handle 14 oriented towards respective forward inner edges 
11a and 11b of the plate member 11 to permit manual projection of the 
apparatus in a cross-cutting procedure when a workpiece is positioned in 
abutment against the forward edge 11a. A guide member 16 is slidably 
mounted throughout the plate member 11 and is mounted in a sliding 
relationship within a dove tail groove 17 that is oriented parallel to a 
plane defined by the rotary saw blade 15 and spaced relative thereto a 
predetermined spacing. A guide plate 19 is orthogonally mounted to a 
forward end of the guide member 16 and is oriented orthogonally relative 
to the bottom surface of the plate member 11. The dove tail groove 17 
slidably receives a complementary "T" shaped projection 18 formed to a top 
end of the guide member 16, in a manner as illustrated in FIG. 5. An 
arcuate guide handle 20 projects upwardly relative to the top surface of 
the plate member 11 and rearwardly of the guide member 16. The projection 
18 is coextensive with the guide member 16, whereupon positioning of the 
guide plate 19 relative to a side edge of a workpiece that is positioned 
adjacent the forward edge 11a and the plate member 11 is directed across 
the workpiece, whereupon the guide member 16 is slidably directed 
rearwardly thereof. The guide plate 19 is spaced from the rotary saw blade 
15 a further spacing less than the predetermined spacing between the guide 
member 16 and the blade 15 to permit the guide plate 19 to pass 
unobstructed along the bottom surface of the plate member 11. 
With reference to FIG. 7, the modified plate member 111 includes a slot 23 
that extends through the plate member 111 medially of the dove tail groove 
17 to receive the guide member 16. Rotatably mounted within the guide 
member 16 is a support boss 24 that includes a threaded shaft 25 that is 
orthogonally directed into a top surface of the support boss 24 projecting 
through the slot 23 and secured at a predetermined relative rotative 
orientation relative to the guide member 16 by the securement fastener 26 
that is threadedly and rotatably mounted onto the threaded shaft 25 above 
the top surface of the modified plate member 111. The support boss 24 
includes a downwardly extending apertured projection that is received 
between a plurality of spaced ears formed to a top edge of the modified 
guide plate 19a. An axle 27 is directed through the ears and the 
downwardly extending projection of the support boss 24 to permit pivotment 
of the guide plate 19a. Further, a spring member 28 mounted about the axle 
27 is arranged to normally bias the guide plate in an orthogonal 
orientation relative to the plate member 111. In this manner, the guide 
plate 19a may be rotatably oriented relative to a wooden workpiece to 
permit angular ripping of the workpiece relative to a side edge thereof, 
as well as permitting deflection of the guide plate 19a upon directing the 
saw member across the workpiece. 
As to the manner of usage and operation of the instant invention, the same 
should be apparent from the above disclosure, and accordingly no further 
discussion relative to the manner of usage and operation of the instant 
invention shall be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to 
one skilled in the art, and all equivalent relationships to those 
illustrated in the drawings and described in the specification are 
intended to be encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
described, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
