Abstract
Abstract An apparatus for spraying between the rows of a plurality of rows of glass containers moving on a lehr mat. The spray traversing mechanism is of a commercial type which is mounted to extend through an opening in the roof of the lehr. The spraying device traverses transversely of the lehr mat. One end of the mechanism for supporting the spray traversing mechanism is pivotally mounted to a first wheeled member which is capable of being longitudinally and adjustably positioned at one side of the lehr. The other end of the traversing device is pivotally mounted to a second wheeled member, with the second wheeled member being reciprocated parallel to the direction of the movement of the lehr mat. The second wheeled member is moved at a rate such that the spray head will spray between the rows of bottles as they are moved on the lehr mat. The apparatus is designed such that conventional non-row-following lehr spray mechanisms may be converted to a row-following mechanism by following the teachings of the present invention.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
235 words
In apparatus for spraying between the rows of objects arrayed in rows and columns within a lehr and that are continuously being moved by a conveyor wherein a traversing spray unit is mounted to extend into the interior of and extend transversely across the lehr, said unit including a movable carriage that is reciprocated across said lehr, the improvement comprising: a pair of horizontal rails at either side of the top of said lehr, said rails extending parallel to the movement of the conveyor; a first wheeled member mounted for longitudinal movement on one of said rails; a second wheeled member mounted for longitudinal movement on the other of said rails; a laterally extending support member pivotally connected to both said wheeled members at opposite ends thereof; a mounting post extending upward from each of said support member, said traversing spray unit mounted to and extending between said mounting posts; means for positioning one of said wheeled members relative to its rail; and means for reciprocating the other of said wheeled members, said means for reciprocating the other of said wheeled members includes means for adjusting the length of the stroke of said reciprocating means whereby the spray unit is adapted to follow rows of objects moving on said conveyor regardless of the spacing of the rows of objects relative to each other by being capable of being adjusted to the spacing of the rows.
Claim 2
Dependent Claim

In apparatus for spraying between the rows of objects arrayed in rows and columns within a lehr and that are continuously being moved by a conveyor wherein a traversing spray unit is mounted to extend into the interior of and extend transversely across the lehr, said unit including a movable carriage that is reciprocated across said lehr, the improvement comprising: a pair of horizontal rails at either side of the top of said lehr, said rails extending parallel to the movement of the conveyor; a first wheeled member mounted for longitudinal movement on one of said rails; a second wheeled member mounted for longitudinal movement on the other of said rails; a laterally extending support member pivotally connected to both said wheeled members at opposite ends thereof; a mounting post extending upward from each of said support member, said traversing spray unit mounted to and extending between said mounting posts; means for positioning one of said wheeled members relative to its rail; and means for reciprocating the other of said wheeled members, said means for reciprocating the other of said wheeled members includes means for adjusting the length of the stroke of said reciprocating means whereby the spray unit is adapted to follow rows of objects moving on said conveyor regardless of the spacing of the rows of objects relative to each other by being capable of being adjusted to the spacing of the rows.
Claim 3
Dependent Claim
50 words
The apparatus of claim 1, wherein said lateral support member is pivoted to said wheeled members by a thrust bearing interposed therebetween, said thrust bearing having a lower, race supporting ring, welded to said wheeled members, and bolt means holding said thrust bearing and lateral support member in assembled relationship.
Claim 4
Dependent Claim
28 words
The apparatus of claim 1, wherein said reciprocating drive means comprises a fluid motor, said motor having its piston rod connected to the other of said wheeled members.
Claim 5
Dependent Claim
41 words
The apparatus of claim 3, wherein the piston rod is connected to one end of an arm, means pivotally supporting said arm intermediate its length, and means connecting the other end of said arm to the other of said wheeled members.
Claim 6
Dependent Claim
37 words
The apparatus of claim 4, further including means for adjusting the pivot position of said arm, thereby changing the extent of movement of the other end of said arm in relation to the stroke of the motor.
Claim 7
Dependent Claim
27 words
The apparatus of claim 5, wherein said arm pivot adjusting means comprises a threaded rod connected to a pivot block that is slideable in a slotted casting.
Claim 8
Dependent Claim
25 words
The apparatus of claim 6, further including means connected to said rails for limiting the extent of movement of said wheeled members on said rails.
