Abstract
A dual-axis table assembly has left and right sector plates mounted on the underside of a table. Each sector plate is seated on a respective left and right pair of shoes which are mounted on a base. A left handwheel operates to turn the left sector for front/rear table tilting, and a right handwheel operates to change the distance between the right pair of shoes for right/left table tilting. A clamp mechanism grips the left sector wheel when the table is locked in adjusted position.
Claims8
A dual-axis table assembly comprising:
- a table having a front and back, and left and right ends,
- a base spaced beneath said table;
- left and right sector members each having a center of curvature, said members depending rigidly from said table and spaced apart in parallel relation perpendicular to a left to right axis passing through each of their centers of curvature;
- left and right pairs of support elements on said base supporting said left and right sector members, respectively, said left pair of elements supporting said left sector member at left support locations spaced apart in a front to back direction relative to said table, and said right pair of elements supporting said right sector member at right support locations spaced apart in a front to back direction relative to said table;
- left adjustment means carried by said base for turning said left sector member on said left pair of support elements with respect to said axis and thereby tilting said table and right sector member in a front/back direction relative to said base;
- and
- right adjustment means carried by said base for adjusting the distance between said right pair of elements to vary the distance between said right support locations to thereby selectively raise or lower said right sector member and responsively tilt said axis, table, and both sector members in a right/left direction relative to said base.

A dual-axis table assembly comprising:
- a table have a front and back, and left and right ends;
- left and right sector members each having a center of curvature, said members depending rigidly from said table and spaced apart in parallel relation perpendicular to a left to right axis passing through each of their centers of curvature;
- left and right pairs of contact elements carried by a base and supporting said left and right sector members, respectively, said left pair of elements supporting said left sector member at left support locations spaced apart in a front to back direction relative to said table, and said right pair of elements supporting said right sector member at right support locations spaced apart in a front to back direction relative to said table;
- a crank pin connected to said left sector member;
- left adjusting means carried by said base and connected to said crank pin for selectively moving it forwardly or rearwardly for front/back tilting of said table relative to said base;
- front and back slide blocks on said base carrying said right pair of contact elements;
- and right adjustment means carried by said base for sliding said slide blocks toward or away from one another to vary the distance between said right support locations and thereby selectively raise or lower said right sector member for left/right tilting of said table relative to said base;
- a clamp on said base arranged to engage said left sector member;
- means for selectively engaging and disengaging said clamp;
- a longitudinal shaft on said axis extending between said sector members;
- and hold-down means extending between said base and longitudinal shaft and biasing the latter downwardly and to the left.

A dual axis table assembly comprising,
- a table having front and back sides, and right and left ends;
- right and left sector plates depending from rigid connections with said table, said sector plates having arcuate rim faces and having their center of curvature on a common longitudinal axis parallel to said table;
- a base spaced beneath said table;
- right and left pairs of spaced apart shoes mounted on said base said right pair of shoes being spaced apart in a front to back direction relative to said table, and said left pair of shoes being spaced apart in a front to back direction relative to said table;
- said right sector plate having its rim face engaging said right pair of shoes and right spaced apart support locations, and said left sector plate having its rim face engaging said left pair of shoes at left spaced apart support locations;
- first adjustment means carried by said base for adjusting the distance between the shoes in said right pair to vary the distance between said right support locations and thereby selectively raise and lower said right sector plate and thereby tilt said table left or right relative to said base;
- second adjustment means carried by said base for turning said sector plates together with respect to said longitudinal axis to selectively tilt said table to the back or front relative to said base;
- and clamping means for selectively locking said left sector plate to said base against endwise motion or turning movement.
