Abstract
Abstract Apparatus for automatically spraying the sides and the top of workpieces such as vehicle bodies as they are conveyed through a spray station. Separate apparatus is provided for spraying the two sides and the top of the conveyed workpiece. Each apparatus is capable of moving one or more spray guns both in a direction transverse to the movement of the conveyed workpiece and towards and away from the conveyed workpiece, and of rotating the spray guns about two axes to direct the spray guns perpendicular to the surface being coated.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
Improved contour following apparatus for positioning a paint spray gun for coating a workpiece moving along a predetermined path along a first axis comprising first, second, third and fourth explosion-proof electric motors, means responsive to said first motor for moving said spray gun along a second axis in a direction perpendicular to said first axis, means responsive to said second motor for moving said spray gun along a third axis in a direction perpendicular to said first and second axes, means responsive to said third motor for rotating said spray gun about an axis parallel to said second axis, means responsive to said fourth motor for rotating said spray gun about an axis parallel to said first axis, and wherein said second motor is stationary.
Claim 2
Dependent Claim
125 words
Improved contour following apparatus for positioning a paint spray gun for coating a workpiece moving along a predetermined path along a first axis comprising first, second, third and fourth explosion-proof electric motors, means responsive to said first motor for moving said spray gun along a second axis in a direction perpendicular to said first axis, means responsive to said second motor for moving said spray gun along a third axis in a direction perpendicular to said first and second axes, means responsive to said third motor for rotating said spray gun about an axis parallel to said second axis, means responsive to said fourth motor for rotating said spray gun about an axis parallel to said first axis, and wherein said second motor is stationary.
Claim 3
Dependent Claim
56 words

Claim 4
Dependent Claim
79 words
Improved contour following apparatus for positioning a paint spray gun for coating a workpiece moving along a predetermined path along a first axis, as set forth in claim 2, and further including a carriage mounted on said frame to move along said second axis, wherein said first motor is connected to move said carriage along said second axis, and wherein said spray guns are supported on said carriage for rotation about axes parallel to said first and second axes.
Claim 5
Dependent Claim
59 words
Improved contour following apparatus for positioning a paint spray gun for coating a workpiece moving along a predetermined path along a first axis, as set forth in claim 3, wherein said third and fourth motors are connected through angle drive means mounted on said carriage for rotating said spray gun about axes parallel to said first and second axes.
