Abstract
Abstract A mechanism for spraying between the rows of a plurality of rows of moving objects. A conventional traversing spray unit is mounted for linear, transverse motion across a conveyor. The conveyor may be a part of a glass container annealing lehr on which rows of glass containers are carried. A control rail is pivotally connected on one side of the lehr under the spray unit. The other end of the control rail is attached to a reciprocating motor on the opposite side of the lehr. A sliding shoe connects the control rail to a slide plate carried by a movable carriage of the spray unit. The slide plate in turn carries a downwardly directed spray gun. When the reciprocating motor is actuated, the ccontrol rail pivots about its mounting, and moves the slide plate and spray gun. When the carriage moves across the lehr, the slide plate and spray gun will follow a diagonal path dictated by the control rail position. An electrical control system directs cycling of the carriage movement so that the diagonal path followed by the spray gun lies between adjacent, moving rows of glass containers.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
214 words
In an apparatus for spraying objects arrayed in rows and columns that are continuously moved by a conveying means wherein a traversing spray unit is mounted on support columns positioned on opposite sides of said conveying means and extends transversely across said conveying means, and wherein said traversing spray unit includes a movable carriage that is moved by a drive means in a linear path back and forth transversely across said conveying means, the improvement in said apparatus which comprises, in combination: a control rail extending transversely across said conveying means; means for pivotally mounting said control rail adjacent one of said support columns in a location below said traversing spray unit; reciprocating motor means mounted adjacent the other one of said support columns; means for connecting the free end of said control rail to said motor means, whereby said motor means can move said control rail about said means for pivotally mounting said control rail; a slide plate, carried by said movable carriage and slideably mounted thereon for longitudinal movement relative to said conveying means; a sliding shoe, engaged on said control rail and connected to said slide plate; at least one downwardly directed spray means carried by said slide plate; and circuit means for controlling the movement of said traversing spray unit.
Claim 2
Dependent Claim
214 words
In an apparatus for spraying objects arrayed in rows and columns that are continuously moved by a conveying means wherein a traversing spray unit is mounted on support columns positioned on opposite sides of said conveying means and extends transversely across said conveying means, and wherein said traversing spray unit includes a movable carriage that is moved by a drive means in a linear path back and forth transversely across said conveying means, the improvement in said apparatus which comprises, in combination: a control rail extending transversely across said conveying means; means for pivotally mounting said control rail adjacent one of said support columns in a location below said traversing spray unit; reciprocating motor means mounted adjacent the other one of said support columns; means for connecting the free end of said control rail to said motor means, whereby said motor means can move said control rail about said means for pivotally mounting said control rail; a slide plate, carried by said movable carriage and slideably mounted thereon for longitudinal movement relative to said conveying means; a sliding shoe, engaged on said control rail and connected to said slide plate; at least one downwardly directed spray means carried by said slide plate; and circuit means for controlling the movement of said traversing spray unit.
Claim 3
Dependent Claim
19 words
The improvement of claim 1 wherein said reciprocating motor means comprises a fluid motor having an extensible operating member.
Claim 4
Dependent Claim
21 words
The improvement of claim 2 which further includes: means for adjusting the length of the stroke of said extensible operating member.
Claim 5
Dependent Claim
100 words
The improvement of claim 3 wherein said means for adjusting the stroke of said extensible operating member compRises: a threaded shaft, rotatably mounted adjacent said fluid motor; a pair of stop blocks, threadably engaged on said threaded shaft, one of said stop blocks being right-hand threaded and the other of said stop blocks being left-hand threaded, whereby rotation of said threaded shaft will move said stop blocks as a unit toward or away from a fixed center line; and a limit plate, connected to said extensible operating member, said limit plate following a path of travel between said stop blocks.
Claim 6
Dependent Claim
63 words
The improvement of claim 1 wherein said circuit means includes: electrical control means, responsive to the passage of successive rows of said objects, for actuating said motor means and said drive means to thereby cause said control rail to move about its pivotal connection and force said spray means to follow a diagonal path across said conveying means between rows of said objects.
Claim 7
Dependent Claim
37 words
The improvement of claim 5, wherein said electrical control means includes: means positioned adjacent each of said support columns for detecting the presence of said movable carriage and de-activating said drive means in response to such presence.
Claim 8
Dependent Claim
53 words
The improvement of claim 6 wherein said electrical control means includes a main electrical supply and wherein said means for detecting the presence of said movable carriage comprises normally closed limit switches, one positioned adjacent each of said support columns, said limit switches being connected in series across said main electrical power supply.
Claim 9
Dependent Claim
39 words
The improvement of claim 7 wherein said drive means includes a clutch/brake unit, connected to power or brake said carriage, driven by an electrical motor, the clutch portion and the brake portion of said clutch/brake unit being individually controllable.
Claim 10
Dependent Claim
107 words
The improvement of claim 8 wherein said electrical control means further includes: a first normally open contact pair, controlled by a means for sensing the gap between successive rows of said objects, connected in series with said limit switches; a relay coil connected in series with said first normally open contact pair; a second normally open contact pair, controlled by said relay coil, connected in parallel with said relay coil and said first normally open contact pair; and electrically controlled means for actuating said clutch portion of said clutch/brake unit, connected in series with said second normally open contact pair and in parallel with said relay coil.
Claim 11
Dependent Claim
53 words
The improvement of claim 9 wherein said electrical control means further includes: a first normally closed contact pair, controlled by said relay coil, connected across said main electrical power supply; and electrically controlled means for actuating said brake portion of said clutch/brake unit, connected in series with said first normally closed contact pair.
Claim 12
Dependent Claim
97 words
The improvement of claim 10 wherein said electrical control means further includes: a second relay coil, connected across said main electrical supply in series with one of said limit switches, and in parallel with the other one of said limit switches; and a third normally open contact pair, connected in series with and controlled by said second relay coil, said second mentioned limit switch being of the double pole, double throw type having a normally closed terminal connected to said first mentioned limit switch and a normally open terminal connected in series with said second relay coil.
Claim 13
Dependent Claim
