This invention relates generally to the field of sawing and cutting, and also to the field of sanding and grinding.
Miter guides have been used for many years to accomplish accurate angular cuts in work pieces. Miter guides have been invented and manufactured in simple and complex forms.
Prior technology of miter guides can be seen in the following U.S. Pat. Nos. 1,401,560; 3,841,188; 4,002,329; 5,097,601; 5,379,669; 5,771,767; 5,979,283; 6,532,679.
U.S. Pat. Nos. 5,097,601; and 6,532,679 represent simple horizontal plane miter guides. U.S. Pat. Nos. 3,841,188; 4,002,329; 5,379,669; 5,771,767; and 5,979,283 represent other devices used to achieve miter cuts in the horizontal plane by a more complex means. U.S. Pat. No. 1,401,560 represents a miter guide that produces a miter cut between the horizontal and vertical plane. U.S. Pat. Nos. 3,841,188; 4,002,329; 5,097,601; 5,379,669; 5,771,767; 5,979,283; 6,532,679 all produce a miter cut in a work piece in the horizontal plane by the miter guide rotating on a vertical axis. These miter guides do not have the ability to be adjusted in the horizontal to vertical plane by rotation of a horizontal axis. U.S. Pat. No. 1,401,560 has the ability to adjust and rotate on a horizontal axis and does not have the ability to adjust and rotate on a vertical axis. All of the previous miter guides have the limitation of only making a two dimensional cut in a work piece. The first dimension being the plane of the cutting blade and the second dimension being the plane created by the slope or angle of the miter guide that intersects the first plane or dimension.
The multi-dimensional miter has the ability to make the same angular cuts as the previously described miter guides and also adding a third dimension of cutting ability. The first dimension being the plane of the cutting blade, the second dimension being the plane of the platform where the work piece rests, and the third dimension accomplished by rotation either clockwise or counterclockwise from a perpendicular angle to the cutting blade whereby a three dimensional cut is produced at the intersect point of the three planes.
The primary object of the invention is a miter guide that can perform a three-dimensional cut in a work piece in a single pass through a cutting or sawing machine.
Another object of the invention is a miter guide that can be used to sand or grind a work piece to a precise three-dimensional angle.
Another object of the invention is a miter guide that can be adjusted quickly.
A further object of the invention is a miter guide that is easy to use.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
The multi-dimensional miter guide is a device that can produce a three-dimensional cut in a work piece in a single pass through a cutting or sawing machine. The miter guide can also be used to grind or sand a work piece to a specific three-dimensional angular value. The miter guide consists of a base with a radius slotted adjustment path, a work platform, a slotted slope adjustment arm, a slide guide, a degree pointer and a work piece guide plate. The slide guide is attached to bottom of the base which travels the guide groove of a machines work table parallel to the machines action in both directions. The base rotates and locks in many different angular orientations assisted by the degree pointer. An adjustable work platform is attached to the base at the machine end and pivots. The other end of the base and platform are connected by a slotted slope adjustment arm with many different angular orientations.
The drawings constitute a part of this specification and include exemplary embodiments of the invention, which may be embodied in various forms. It is to be understood that in some instances various aspects of the invention may be shown exaggerated or enlarged to facilitate an understanding of the invention.
