Abstract
Abstract A horizontally arranged workpiece supporting table is reciprocally mounted upon a support bed and guided for longitudinal movement, relative to the bed, along a vertically arranged, horizontally axised arc-like curve, beneath a forming tool mounted above the bed upon a slide member moved transversely of the bed along a transversely directed, vertically arranged, horizontally axised arc-like curve. The up and down movement of the workpiece, as the table reciprocates in its curved path beneath the tool, coupled with the up and down transverse movement of the tool forms a predetermined, large radius, compound curved surface upon a plate-like workpiece supported upon the table.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
442 words
An apparatus for forming large radius, compound curves upon a surface of a large, plate-like workpiece, comprising: an elongated, horizontal supported bed with a horizontally arranged table mounted upon the upper surface of the bed for horizontal reciprocal movement along the length of the bed, with the top surface of the table forming a workpiece support for holding a large, horizontally arranged plate-like workpiece; interengaged, cooperating guide means formed on the table and bed for guiding the reciprocal movement of the table along the length of the bed, with said guide means being curved along a large radius arc arranged in a vertical plane wherein the longitudinal reciprocal movement of the table relative to the length of the bed is along an arcuate, horizontally axised, path of a predetermined arcuate radius; a cross member secured at a spaced distance above the bed and between the opposite ends thereof and extending transversely of the bed and over the table transversely to the direction of reciprocation of the table; a slide member mounted upon the cross member for movement along the length of the cross member and interengaged, cooperating guide means formed on the slide member and cross member for guiding the slide member along the length of the cross member, with said guide means being curved along a large radius arc located in a vertical plane which is transverse to the plane of the arc of the table guide means, wherein the slide member may be moved back and forth along the cross or member and above the top surface of the reciprocating table in an arcuately, generally horizontally axised, curved path extending transversely of the bed, said guide means including a first track mounted upon and extending along the length of the cross member, with the upper surface of the track being curved to a predetermined arcuate curvature; and track engaging means formed on the slide member for engaging with the track upper surface for supporting the slide member upon the track, said track engaging means having a large radius curved surface for face to face guiding engagement with the upper surface of the track wherein the slide member moves in its curved path along the track; and said track being removable and replaceable by a corresponding track of different curvature for thereby varying the path of movement of the slide member; tool means mounted upon and depending beneath the slide member for movement with the slide member and for operating upon the upper surface of the workpiece as it reciprocates upon the table beneath the cross member, whereby the tool forms the upper surface of the workpiece into large compound curves.
Claim 2
Independent Claim
442 words
An apparatus for forming large radius, compound curves upon a surface of a large, plate-like workpiece, comprising: an elongated, horizontal supported bed with a horizontally arranged table mounted upon the upper surface of the bed for horizontal reciprocal movement along the length of the bed, with the top surface of the table forming a workpiece support for holding a large, horizontally arranged plate-like workpiece; interengaged, cooperating guide means formed on the table and bed for guiding the reciprocal movement of the table along the length of the bed, with said guide means being curved along a large radius arc arranged in a vertical plane wherein the longitudinal reciprocal movement of the table relative to the length of the bed is along an arcuate, horizontally axised, path of a predetermined arcuate radius; a cross member secured at a spaced distance above the bed and between the opposite ends thereof and extending transversely of the bed and over the table transversely to the direction of reciprocation of the table; a slide member mounted upon the cross member for movement along the length of the cross member and interengaged, cooperating guide means formed on the slide member and cross member for guiding the slide member along the length of the cross member, with said guide means being curved along a large radius arc located in a vertical plane which is transverse to the plane of the arc of the table guide means, wherein the slide member may be moved back and forth along the cross or member and above the top surface of the reciprocating table in an arcuately, generally horizontally axised, curved path extending transversely of the bed, said guide means including a first track mounted upon and extending along the length of the cross member, with the upper surface of the track being curved to a predetermined arcuate curvature; and track engaging means formed on the slide member for engaging with the track upper surface for supporting the slide member upon the track, said track engaging means having a large radius curved surface for face to face guiding engagement with the upper surface of the track wherein the slide member moves in its curved path along the track; and said track being removable and replaceable by a corresponding track of different curvature for thereby varying the path of movement of the slide member; tool means mounted upon and depending beneath the slide member for movement with the slide member and for operating upon the upper surface of the workpiece as it reciprocates upon the table beneath the cross member, whereby the tool forms the upper surface of the workpiece into large compound curves.
Claim 3
Dependent Claim
36 words
An apparatus as defined in claim 1, and means for mounting said cross member at predetermined angles relative to the longitudinal axis of the bed for thereby varying the curves formed upon the workpiece upper surface.
Claim 4
Dependent Claim
47 words
An apparatus as defined in claim 1, and said table guide means and said slide member guide means, each being removable and replaceable with corresponding guide means of different arc radii for thereby varying the curvature of the paths of movement of the table and slide member.
Claim 5
Dependent Claim
85 words
An apparatus as defined in claim 1, and said table guide means comprising interfitted tongue and groove members secured to the table and bed, with the groove and the groove member being lined with removable bushings having arcuately curved tongue engaging surfaces engaged with corresponding curved surfaces found on the tongue of the tongue member, with the bushings and tongue being removable and replaceable by corresponding, but differedly curved, bushing and tongues for thereby changing the curvature of the path of movement of the table.
Claim 6
Dependent Claim
60 words
An apparatus as defined in claim 1, and said guide means including an additional track vertically aligned with the first track, said additional track having an arcuate curvature complementary in shape to the curvature on the first track, and said track engaging means including an additional large radius curved surface for face to face guiding engagement with the additional track.
Claim 7
Dependent Claim
62 words
An apparatus as defined in claim 1, and said guide means including an additional track parallel to and horizontally spaced from the first track, said additional track having an arcuate surface with a different radius of curvature than the first track, and said track engaging means including a second curved surface for selective face to face guiding engagement with the additional track.
