Claims
- 1. In a mat cutting maching, the combination comprising:
- a base;
- a handle assembly pivotably mounted upon said base for movement between a position overlying the upper, mat-supporting surface of said base, and a position displaced therefrom;
- a clamping bar assembly pivotably mounted by said handle assembly and including an elongated clamping bar and substantially coextensive guide rail, said clamping bar having a substantially planar bottom surface and being adapted to rest with said bottom surface substantially upon said upper surface of said base with said handle assembly in said overlying position thereof, and said guide rail being affixed to the upper side of said clamping bar and adapted to slidably mount a cutting head assembly for movement therealong; and
- a stop assembly slidably mounted upon said rail for movement therealong, said stop assembly comprising a body having a clamping portion slidably mounted upon said rail and including clamping means for securing said stop assembly in selected positions therealong, and a supporting portion extending laterally from said clamping portion, said supporting portion having an elongated rule body slidably mounted thereon for extension along an axis parallel to the axis of said rail, with cooperating means thereon for affixing said rule body in selected positions of extension, said rule body in turn having a stop element mounted thereon for adjustable extension therefrom along said parallel axis, said supporting portion also having a locating subassembly mounted thereon and including a spring element extending from said supporting portion along another axis generally parallel to said rail axis and in the direction of extension of said stop element, and a locating element adjacent a free end of said spring element, said locating element normally being disposed above said upper surface of said base with said handle assembly in said overlying position thereof, and being resiliently deflectable on said spring element into contact therewith.
- 2. The combination of claim 1 wherein said spring element is in strip form, and said locating element is a lug extending downwardly from adjacent the outer end thereof.
- 3. The combination of claim 1 wherein said clamping portion of said stop assembly body comprises an inner, resiliently deflectable component and an outer, relatively rigid component, said inner component having a surface element in contact with said rail, and said outer component mounting a clamping screw having one end portion in contact with said inner component to permit the application of deflective force thereon by adjustment of said clamping screw, such adjustment serving to bring said surface element of said inner component into clamping engagement with said rail for affixing said stop assembly in selected positions therealong.
- 4. The combination of claim 1 additionally including a squaring guide assembly and an elongated, rectilinear guide bar affixed on said base upper surface in position to lie to one side of said clamping bar assembly, and extending perpendicular to said rail axis, when said handle assembly is in said overlying position thereof, said squaring guide assembly including a slide subassembly comprising a body slidably mounted upon said guide bar for movement to each of several positions spaced at different distances from said clamping bar assembly, and having inner and outer opposite lateral edge portions each with a step element thereon, said combination additionally including positioning means affixable at various points along said guide bar for alternative contact, at least at one of said points, with both of said stop elements on said slider body, to thereby locate said slider subassembly at each of said several positions relative to said clamping bar assembly.
- 5. The combination of claim 4 wherein said guide bar has a series of apertures therein at spaced points along the longitudinal axis thereof, and wherein a pin engageable in said apertures cooperates therewith to provide said positioning means.
