Abstract
Abstract A spray gun for coating surfaces of a succession of articles of different shapes and sizes has the position of emission of liquid therefrom maintained substantially at a predetermined distance from the surface being sprayed by a variable profile cam the profile of which is automatically varied by adjusting means operable under control of control means which in turn is controlled by sensing devices located along the path of the article and which are arranged to sense the shape and size of the article.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
177 words
Apparatus for coating surfaces of a succession of articles of different shapes and sizes by a spray gun reciprocable along a path in a first plane during movement of the surfaces past the gun along a path in a second plane at right angles to said first plane, comprising sensing devices located along the path of the articles and operable to sense the shape and size of the articles, a cam formed by at least two profile-forming members supported for movement relative one to the other to vary the profile of the cam and to control the movements of the gun in said first plane, profile-forming member adjusting means, and control means connected with said sensing devices and said profile-forming member adjusting means and operable to actuate the profile-forming member adjusting means to vary the profile of the cam according to the form of the surface to be sprayed during reciprocation of the spray gun to maintain the position of emission of liquid from the spray gun substantially at a predetermined distance from the surface being sprayed.
Claim 2
Dependent Claim
177 words
Apparatus for coating surfaces of a succession of articles of different shapes and sizes by a spray gun reciprocable along a path in a first plane during movement of the surfaces past the gun along a path in a second plane at right angles to said first plane, comprising sensing devices located along the path of the articles and operable to sense the shape and size of the articles, a cam formed by at least two profile-forming members supported for movement relative one to the other to vary the profile of the cam and to control the movements of the gun in said first plane, profile-forming member adjusting means, and control means connected with said sensing devices and said profile-forming member adjusting means and operable to actuate the profile-forming member adjusting means to vary the profile of the cam according to the form of the surface to be sprayed during reciprocation of the spray gun to maintain the position of emission of liquid from the spray gun substantially at a predetermined distance from the surface being sprayed.
Claim 3
Dependent Claim
65 words
Apparatus according to claim 1, wherein the profile-forming members each include a U-section channel, and a cam profile-forming strip extending lengthwise of the bases of the U-section channels, said channels being pivoted one to another and movable about their pivots by the adjusting means to vary the profile formed by the strip and to effect curving of the strip between adjacent ends of the channels.
Claim 4
Dependent Claim
102 words
Apparatus according to claim 1, wherein there are first and second profile-forming members each consisting of a U-section channel, and a cam profile-forming strip extending lengthwise of the bases of the U-section channels, the channel of the second member being straight along the length thereof and the channel of the first member having a straight portion terminating in a curved portion adjacent one end of the channel of the second member, the adjacent ends of the channels being secured to brackets pivotable about a fixed pivot and the ends of the channels remote from each other being connected to said adjusting means.
Claim 5
Dependent Claim
155 words
Apparatus according to claim 1, wherein there are first, second, and third profile-forming members each consisting of a U-section channel, each said channel being straight along the length thereof, a cam profile-forming strip extending lengthwise of the bases of the channels, arms secured to opposite ends of the channels of the second member and extending in opposite directions at right angles thereto, a rocking arm rockable about a pivot therefor, said rocking arm carrying pivots at the opposite ends thereof and having said arms pivoted on said pivots, and brackets secured to the ends of the channels of the first and third members adjacent the opposite ends of the channel of the second member, said brackets being pivoted one on each of the pivots carried by the rocking arm and the ends of the channel of the first and third members remote from the channel of the second member being connected to said adjusting means.
Claim 6
Dependent Claim
17 words
Apparatus according to claim 4, including further adjusting means for rocking the rocking arm about its pivot.
Claim 7
Dependent Claim
23 words
Apparatus according to claim 2, wherein the adjusting means includes fluid-operated cylinders having pistons connected to the pivotable parts of the cam structure.
Claim 8
Dependent Claim
23 words
Apparatus according to claim 3, wherein the adjusting means includes fluid-operated cylinders having pistons connected to the pivotable parts of the cam structure.
Claim 9
Dependent Claim
23 words
Apparatus according to claim 4, wherein the adjusting means includes fluid-operated cylinders having pistons connected to the pivotable parts of the cam structure.
Claim 10
Dependent Claim
23 words
Apparatus according to claim 5, wherein the adjusting means includes fluid-operated cylinders having pistons connected to the pivotable parts of the cam structure.
Claim 11
Dependent Claim
172 words
Apparatus for coating surfaces of a succession of articles of different shapes and sizes by a spray gun reciprocable along a first path in a first plane during movement of the surfaces past the gun aloNg a path in a second plane at right angles to said first plane, comprising in combination: sensing means located along the path of the articles for sensing the size and shape of the articles; a spray gun and means for moving said spray gun along said first path; variable profile cam means disposed along said first path and engaged by said means for moving the spray gun for controlling in and out movements of the gun relative to said second plane as it is moved along said path in said first plane; and control means for varying the profile of said cam means in accord with the size and shape of the article sensed by said sensing means to maintain said spray gun substantially at a predetermined distance from the surface of an article being sprayed.
