Claim 1
Independent Claim
172 words
A sawing guide tool to increase the speed and accuracy of an individual or identically repeated sawing operation on a suitably sawable flat or substantially flat material, said tool comprising a pair of completely flat metal strips being one on top of the other, which, when together can become longitudinally extensible, one of said metal strips having a lengthwise slot in which a set screw on the other strip may become positioned, tightly clamping said two flat metal strips together to obtain a given lengthwise dimension of said pair of metal strips, and a quick closing clamp mounted on one end of one of one of said flat metal strips, to temporarily hold the tool tightly against the work to be sawed, one clamping element of said quick closing clamp gripping the opposite surface of the flat piece to be sawed, in order to firmly guide the proper direction of the saw as it moves closely along against said pair of completely flat metal strips until the sawing operation has been completed.
