Abstract
A mat cutting machine utilizes a trolley which runs smoothly and accurately along a shaft mounted upon the clamping bar assembly. Means is provided for precisely adjusting the relationship between the bevel cutting blade and the edge of the clamping bar, and the blades are held by magazines which permit ready interchangeability and facile adjustment of the amount of blade protrusion so as to enable the cutting depth to be altered with considerable ease. The base of the machine includes means for accurately positioning the workpiece, and for readily controlling the travel of the trolley, to afford high volume production capability.
Claims5
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.
