Cutting guide

Claim 2

A cutting guide for orienting an object in a predetermined spatial relationship with respect to a cutting means, such as a band saw blade, comprising: a. a fixed base; b. an upright guide support reciprocally mounted to said base for movement toward and away from said cutting means; c. an upright open frame connected to said guide support, said frame having an internal semi-circular track; d. a platform in vertical alignment with said frame and spaced at least partially within the inner periphery of the frame; e. means connecting the frame and platform to permit the platform to be selectively rotated about its horizontal and vertical axes and f. carriage means movably connected to said platform for supporting the object to be cut, said carriage means adapted to be radially rotated about the face of the platform.

Claim 3

The invention in accordance with claim 1 wherein said frame is vertically adjustable with respect to said guide support.

Claim 4

The invention in accordance with claim 1 wherein said carriage means contains a plurality of telescoping arms adapted to be moved toward and away from said platform to support said object during cutting.

Claim 5

A cutting guide for orienting an object in a predetermined spatial relationship with respect to a cutting means, such as a band saw blade in ordeR to form an arcuate edge on said object of predetermined radius, predetermined edge angle and predetermined edge pitch comprising: a. a fixed base having an open horizontal track; b. an upright guide support having a runner adapted for reciprocal motion in said track; c. an upright open C frame having an internal semi-circular track; d. means connecting said guide support and upright frame adapted to move said frame toward and away from said guide support; e. a circular platform vertically aligned with said frame and spaced at least partially within the inner periphery of said frame, said platform having a pair of bosses diametrically opposed on the periphery of said platform; f. a C-shaped rail adapted for movement within said semi-circular track, said rail adapted to receive each of said bosses and hold said bosses against lateral movement and permit rotation of said bosses about said vertical axes of said bosses; g. first and second carriage plates pivotally connected to said platform extending normal to the plane of said platform; h. means for adjustably positioning each of said plates at a predetermined angle with respect to a local horizontal; and i. a plurality of radially extending telescoping arms in each of said plates for supporting said object to be cut.

Claim 6

A cutting guide for orienting an object in a predetermined spatial relationship with respect to a cutting means, such as a band saw blade in ordeR to form an arcuate edge on said object of predetermined radius, predetermined edge angle and predetermined edge pitch comprising: a. a fixed base having an open horizontal track; b. an upright guide support having a runner adapted for reciprocal motion in said track; c. an upright open C frame having an internal semi-circular track; d. means connecting said guide support and upright frame adapted to move said frame toward and away from said guide support; e. a circular platform vertically aligned with said frame and spaced at least partially within the inner periphery of said frame, said platform having a pair of bosses diametrically opposed on the periphery of said platform; f. a C-shaped rail adapted for movement within said semi-circular track, said rail adapted to receive each of said bosses and hold said bosses against lateral movement and permit rotation of said bosses about said vertical axes of said bosses; g. first and second carriage plates pivotally connected to said platform extending normal to the plane of said platform; h. means for adjustably positioning each of said plates at a predetermined angle with respect to a local horizontal; and i. a plurality of radially extending telescoping arms in each of said plates for supporting said object to be cut.
