ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a system for enhancing the surface of a building block. More particularly the present invention relates to an improvement for cutting material away from the surface of a building block to improve the aesthetic appearance of that surface.
2. Description of the Related Art
The inventor's U.S. Pat. No. 5,496,206, incorporated herein by this reference, discloses an earlier generation of an apparatus for removing a layer of material from a building block to give the block a similarity in appearance to granite and marble.
The present invention is an improvement of the invention disclosed in the above-mentioned patent.
BRIEF SUMMARY OF THE INVENTION
The improved system comprises in combination a conveyer assembly including a conveyer belt to receive and support an object such a building block to be enhanced, a frame assembly including a base frame for supporting the conveyer assembly and a head frame mounted to the base frame, a moveable stage frame supported by the frame assembly, a plurality of moveable mounting platforms supported by the stage frame, a plurality of cutting apparatus each of the cutting apparatus mounted to a platform, a means connected to the stage frame for moving the mounting platforms in relation to the stage frame, and means connected to the frame assembly for moving the stage frame relative to the frame assembly.
An object of the present invention is to provide a surface enhancing system for building blocks which is relatively simple, easy to use, easy to adjust, relatively inexpensive and reliable. Another aspect of the present invention is to provide a surface enhancing system for building blocks which has a relatively long enduring cutting tool and an excellent rate of operation. Another aim of the present invention is to provide a surface enhancing system that can grind a new surface on the block at an oblique angle as so as to provide a “beveled” surface block
A more complete understanding of the present invention and its objects, aspects, aims and advantages thereof will be gained from a consideration of the following description of the preferred embodiments read in conjunction with the accompanied drawings provided herein.
