Abstract
Abstract A guide for a portable power saw, attachable to such a saw, which enables the operator to make straight cuts with said power saw at a uniform angle to the sides of the work being sawed. A fixed bearing member of the guide is attached to the portable power saw, with a slidable mating member fitting into said bearing member, said slidable mating member being equipped with a rotatable end stop for alignment with the work being sawed. The rotatable end stop may be locked in place by means of a screw fastener, and the angle of said stop member to the plane of the saw cut is displayed on a protractor scale fixed to the sliding member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
205 words
A guide apparatus for attachment to a portable power rotary saw which enables said saw to travel in a straight line at a uniform angular relation to an edge of the work being cut, with provisions for adjusting and setting of said angle consisting of an attachment member adaptable for fastening in a rigid manner to the power saw frame in front of the saw cutting edge, said attachment member being of the general shape of a hollow rectangular tube, together with a guide arm assembly which has a protruding rectangular bar that fits in mating engagement inside of the rectangular hollow of said attachment member, said attachment member having threaded means to rigidly fasten to the bar of the guide arm assembly inserted inside of the hollow of the attachment member, said guide arm assembly having sliding means linked to a stop member which is adaptable to resting against one edge of a board to be sawed, the linkage of said stop member to said sliding means being adaptable to angular adjustment, such that, in the fully assembled condition to a power saw, the sliding means permit the linear motion of the power saw in one fixed direction relative to the linked stop member.
Claim 2
Dependent Claim
205 words
A guide apparatus for attachment to a portable power rotary saw which enables said saw to travel in a straight line at a uniform angular relation to an edge of the work being cut, with provisions for adjusting and setting of said angle consisting of an attachment member adaptable for fastening in a rigid manner to the power saw frame in front of the saw cutting edge, said attachment member being of the general shape of a hollow rectangular tube, together with a guide arm assembly which has a protruding rectangular bar that fits in mating engagement inside of the rectangular hollow of said attachment member, said attachment member having threaded means to rigidly fasten to the bar of the guide arm assembly inserted inside of the hollow of the attachment member, said guide arm assembly having sliding means linked to a stop member which is adaptable to resting against one edge of a board to be sawed, the linkage of said stop member to said sliding means being adaptable to angular adjustment, such that, in the fully assembled condition to a power saw, the sliding means permit the linear motion of the power saw in one fixed direction relative to the linked stop member.
Claim 3
Dependent Claim
72 words
The combination recited in claim 1 in which a recess is located in the attachment member and in the mating bar of the guide arm assembly, said recess being located directly in front of the cutting edge of the saw blade so as to permit viewing by the operator of a portion of the cutting path of the saw blade, ahead of the saw blade, which lies under the guide arm assembly.
Claim 4
Dependent Claim
52 words
The combination recited in claim 1 in which the bar of the guide arm assembly is rigidly mounted at right angles to a slide bar which slides inside of the sliding means of the guide arm assembly, the direction of said sliding being at right angles to the axis of the bar.
