Abstract
A compound miter box is provided wherein the saw guides are pivotable about a vertical and a horizontal axis. Each saw guide includes a retaining mount having a concave bearing surface defining a locating tab thereon. A saw supporting arm is pivotally mounted to the underside of the saw bench. The arm includes a plurality of tab receiving depressions therein. Each tab receiving depression corresponds to a predetermined angle between the saw guides and the saw bench. A user may then select and secure the locating tab in a tab receiving depression corresponding to the desired predetermined angle between the saw guides and the work supporting surface of the bench.
Claims32
A compound miter box, comprising:
- a generally rectangular bench;
- an arm having first and second ends, the arm pivotally mounted to and supported under the bench;
- first and second retaining mounts, each retaining mount having an arcuate retaining surface and the first retaining mount having a tab defined on the arcuate retaining surface;
- first and second saw supports, each saw support having a pair of spaced parallel guide rods mounted to a corresponding one of said retaining mounts;
- first and second receiving mounts, each receiving mount mounted to a corresponding one of said ends of the arm and including an arcuate receiving surface, the arcuate receiving surface of the first receiving mount defining a plurality of tab receiving depressions therein such that each tab receiving depression corresponds to a predetermined angle between each rod of the saw supports and the bench, wherein each retaining mount is supported within a corresponding one of said receiving mounts such that each arcuate retaining surface forms a slidable interface with a corresponding arcuate receiving surface and the tab defined on the arcuate retaining surface of the first retaining mount is received within a user selected one of said tab receiving depressions in the arcuate receiving surface of the first receiving mount.
A compound miter box, comprising:
- a saw bench having an upper work supporting surface, and an underside;
- a saw supporting arm having first and second ends, the saw supporting arm mounted to the underside of the saw bench and
- first and second saw supports, each saw support including a pair of spaced parallel saw guide rods and a retaining mount, the retaining mount of the first saw support including an arcuate bearing surface defining a locating tab thereon;
- first and second receiving mounts, each receiving mount extending from a corresponding one of said ends of the saw supporting arm, the first receiving mount including an arcuate bearing surface defining a plurality of tab receiving depressions therein, each tab receiving depression corresponding to a predetermined angle between the saw guide rods and the work supporting surface of the bench and dimensioned for receiving the locating tab therein;
- and
- means for securing the locating tab of the retaining mount of the first saw support in a user selected one of said tab receiving depressions in the first receiving mount.
A compound miter box, comprising:
- a saw bench having an upper work supporting surface, and an underside;
- a saw supporting arm having first and second ends, the supporting arm mounted to the underside of the saw bench and pivotable about a longitudinal axis perpendicular to the work supporting surface;
- first and second saw supports, each saw support including a retaining mount and a pair of spaced, parallel saw guide rods extending therefrom;
- and
- first and second receiving mounts, wherein each receiving mount supports a corresponding one of said retaining mounts such that each of the pair of receiving mounts and the corresponding retaining mount have one of an arcuate bearing surface defining a locating tab thereon and an arcuate bearing surface defining a plurality of tab receiving depressions therein, each tab receiving depression corresponding to a predetermined angle between the saw guide rods and the work supporting surface of the bench and dimensioned for receiving the locating tab therein.
