Abstract
Abstract A coating apparatus including a programmed, movable member carrying coating means dispensing particles of a protective or decorative coating material toward the irregular surface contours of the front and the rear of automobile bodies. The programmed member displaces the coating member in a vertical direction across the irregular surface contours of the automobile bodies, maintains a substantially uniform distance between the coating means and the plane of the irregular surface contours of the automobile body to be coated and aligns the axis of the coating means with respect to the plane of the irregular surface contours of the automobile bodies so as to be substantially perpendicular with such plane of the automobile bodies when dispensing the protective or decorative coating material toward the automobile bodies. A method of coating a series of articles with a protective or decorative coating material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
213 words
A coating apparatus including means for transporting spaced apart articles including front and rear surfaces having irregular contours to be coated through a coating zone, coating means including nozzle means for dispensing particles of coating material toward the articles as the articles pass through the coating zone to deposit particles of coating material upon the articles, programmed movable member means including arm means carrying the coating means and fixedly retaining the axis of the nozzle means of the coating means at a right angle to the arm means, the movable member means including means for maintaining the nozzle means at a determined distance from the irregular surface contours of the articles by pivoting the arm means in the direction of movement of the articles about a pivot point removed from the coating means, and means for moving the coating means into the space between adjacent articles and simultaneously dispensing particles of coating material toward the front surface of one of the articles and toward the rear surface of the adjacent article in the coating zone, the means moving the nozzle means of the coating means across each of the spaced apart articles in a plane transverse to the direction of movement of the articles as the articles are transported through the coating zone.
Claim 2
Dependent Claim
213 words
A coating apparatus including means for transporting spaced apart articles including front and rear surfaces having irregular contours to be coated through a coating zone, coating means including nozzle means for dispensing particles of coating material toward the articles as the articles pass through the coating zone to deposit particles of coating material upon the articles, programmed movable member means including arm means carrying the coating means and fixedly retaining the axis of the nozzle means of the coating means at a right angle to the arm means, the movable member means including means for maintaining the nozzle means at a determined distance from the irregular surface contours of the articles by pivoting the arm means in the direction of movement of the articles about a pivot point removed from the coating means, and means for moving the coating means into the space between adjacent articles and simultaneously dispensing particles of coating material toward the front surface of one of the articles and toward the rear surface of the adjacent article in the coating zone, the means moving the nozzle means of the coating means across each of the spaced apart articles in a plane transverse to the direction of movement of the articles as the articles are transported through the coating zone.
Claim 3
Dependent Claim
25 words
The coating apparatus of claim 1, wherein the coating means includes electrostatic coating means adapted to be connected to a high voltage direct current source.
Claim 4
Dependent Claim
17 words
The coating apparatus of claim 2, wherein the electrostatic coating means includes an air-atomizing electrostatic coating device.
Claim 5
Dependent Claim
69 words
The coating apparatus of claim 1, wherein the programmed member means aligns the axis of the nozzle means with respect to the planes of the irregular surface contours of each of the articles so as to be substantially perpendicular to such planes of each of the surface contours of the articles during at least a portion of the time the coating means is dispensing coating material toward the articles.
Claim 6
Dependent Claim
16 words
The coating apparatus of claim 4, wherein the articles having irregular surface contours are automobile bodies.
Claim 7
Dependent Claim
37 words
The coating apparatus of claim 5, wherein the coating means dispenses coating material toward the irregular surface contours of a rear portion of the leading automobile body and of a front portion of the trailing automobile body.
