Definitions

  • This invention is a hand tool used by the installer of gypsum wallboard (wallboard will be referred to as drywall through out this application.)
  • My invention adds more functions to the existing common drywall jabsaw. These function do not affect the only function of the existing saw-rough cutting drywall, but will aid in other tasks encountered during the drywall installation process. The addition of these features make this drywall jabsaw a multi-function tool.
  • This invention consists of three added features to the single purpose drywall saw. These features will perform the following functions.
  • Fig.2 Handle-top view (sheets 3,4 and 5)
  • Fig.4 Handle-end view (sheets 3,4 and 5)
  • Fig.5 Handle-end view (sheets 3,4 and 5)
  • Fig.6 Blade-side view (sheets 2 and 5)
  • My invention as described below is the addition of three useful features to the common, single purpose, drywall jab saw.
  • the saw handle will be best made of a material suitable to withstand the forces exerted on it while being used for its intended purpose.
  • the handle will either be a molded one piece
  • the saw blade will be made of a hardened steel approx. 1/8" thick.
  • the handle and saw blade will be securely held together.
  • Figs. 14 and 15 of sheet 1 contain all 3 improvements that distinguisli this drywall saw
  • Fig.14 shows a top view of the entire drywall ripsaw with a cutting plane line through the length of the handle.
  • Fig.15 is a side view with a cross section of the handle. The details of the handle and blade will be explained in other Figs.
  • Fig. 6 of sheet 5 shows 2 new improvements to the existing blade: a rip guide and teeth at the top of the blade, the teeth will be explained later.
  • the rip guide consists of teardrop shaped holes spaced 1/8" apart at the tip of the teardrop.
  • the numbers shown on the blade are full inch marks. There will be seven holes between each full inch mark. Fraction marks would not be needed since each hole represents 1/8". The inch marks are upside down in the drawing but will be right side up when used as described.
  • the blade end of the handle will be placed against the edge of the drywall with the blade flat against the face of the sheet.
  • the tip of a utility knife (held in the other hand) will be placed in the pointed area of the teardrop shaped hole with enough pressure to puncture the paper surface. With the ripsaw at a right angle to the edge, it and the knife are pulled along the sheet to make an accurate score mark anywhere from 1/4" to 4-3/4 inches.
  • Figs. 2,3 and 4 of sheet 5 show a notch at the end of the handle-this is part of the invention.
  • This notch is used in breaking off very narrow rips of drywall after the sheet has been scored as described in Fig. 6. By placing the notch over the edge of the sheet and applying pressure with the handle and the other hand, the drywall will break with less pressure.
  • the handle provides leverage that reduces stress on the users hands.
  • Fig.3 on sheet 5 shows measurements of the notch that are important to perform this function. The notch tapers from 11/16" to 1/2" which is meant to be used on 1/2" or 5/8" drywall. The best leverage is achieved with a snug fit, this is accomplished by varying the position of the handle as needed. The notch depth shown is 7/8".
  • a handle with a notch measuring 11/16" to 1-1/16" could be made for 3/4" to 1" drywall.
  • Figs. 3 and 5 on sheet 5 show handle measurements important to the ripping function (as described in Fig.6).
  • the blade end of the handle should not be wider than 3/4" when viewed from the top.
  • the blade-to-handle edge should not exceed 3/8" (5/16" is shown in Fig 5 sheet 5).
  • ⁇ drywall sheets are often cut to size directly from a. stack of sheets leaning against a wall, framing etc., the edges do not align in this position. ⁇ With a max. of 3/8", the handle would not interfere with the sheet behind when slid along its edge.
  • Fig 6 of sheet 5 shows teeth at the top of the saw blade, this is an improvement to the existing blade which only has teeth on one side of the blade.
  • the top teeth are less aggressive. This would allow them to make finer cuts, but more importantly, this portion of the saw could be used as a "file" to quickly touch up rough cuts or breaks..
  • the tool would be held in a position that would allow the teeth to rake across the edge as opposed to cutting into it.
  • the fine teeth are more adapt to this function than the coarse teeth are.
  • the fast cutting coarse teeth would remain and be used as intended.
  • the following sheets show drawings with at least one of the three new improvements to the drywall jab saw.
  • Sheet 2 Fig. 8 is a side view of a handle that does not include the notch as described in
  • Fig. 9 is a top or bottom view of the plain handle.
  • Fig. 10 and 12 are end views of the plain handle.
  • Fig. 6 on this sheet (2) is the same as described earlier and is part of the invention.
  • Fig. 13 is a plain blade shown for reference only. This sheet contains a drawing showing only the notched ⁇ handle invention.
  • Fig. 7 is a side view of a blade showing the rip guide as described in Fig. 6 but without the fine teeth at the top.

Abstract

L'invention concerne trois nouvelles caractéristiques qui, seules ou en combinaison, améliorent l'utilité des scies coulissantes pour cloison sèche existantes. Ces trois nouveautés sont caractérisées par l'ajout de fines dents sur la partie supérieure de la lame, d'orifices espacés à égale distance sur la longueur de la lame et qui sont utilisés tant que guides d'entaille, et d'une encoche à l'extrémité du manche conçue pour aider à supprimer les entailles étroites de la cloison sèche.
