Abstract

An apparatus applies dressing fluid to a bowling lane surface in a discreet pattern laterally across a plurality of zones on the bowling lane. A carriage, for movement along a bowling lane, has an applicator mounted thereon for applying the dressing fluid to the bowling lane surface. Dressing fluid is supplied from a reservoir by a plurality of pulse valves which supply the dressing fluid to a plurality of fluid dispersion chambers, each having an inlet connected to one of the pulse valves and having an outlet positioned to apply dressing fluid to the applicator. The outlet has a width equal to the width of one of the zones. A controller is provided for selectively activating each of the pulse valves to discharge a discrete amount of fluid dressing into each dispersion chamber. Each zone may be the width of one board across the bowling alley so that different discrete amounts of oil can be applied to each board. A method is provided to supply discreet amounts of bowling lane dressing to each of a plurality of zones wherein each zone is one board width or portion of a board width.

Claims

1. An apparatus for applying dressing fluid to a bowling lane surface in a discrete pattern laterally across the bowling lane, wherein the bowling lane has a plurality of zones, each zone having a discrete width, said apparatus comprising:

a carriage for movement along the bowling lane;

an applicator mounted laterally across said carriage for applying dressing fluid to the bowling lane surface;

a reservoir for containing a supply of dressing fluid;

a plurality of pulse valves, each of said pulse valves having an inlet for receiving the dressing fluid and an outlet for discharging a predetermined metered amount of the dressing fluid;

fluid conveying means interconnecting said reservoir with said inlet of each of said pulse valves;

a plurality of fluid dispersion chambers, each having an inlet in fluid communication with said outlet of one of said pulse valves for conveying a metered amount of the dressing fluid to said respective dispersion chambers and each having an outlet slit whose width is equal to the width of one of the zones of the bowling lane surface, each of said slits positioned to apply dressing fluid to said applicator; and

control means connected to each of said pulse valves for selective activation of each of said pulse valves to discharge a discrete amount of dressing fluid into each of said dispersion chambers for dispersion through said respective outlet slits onto said applicator for transfer to the bowling lane surface.

2. Apparatus, as claimed in claim 1, wherein said fluid conveying means includes:

a manifold;

a conduit interconnecting said reservoir and said manifold for conveying dressing fluid from said reservoir to said manifold; and

means interconnecting said manifold with each of said pulse valves for supplying dressing fluid to said pulse valves.

3. Apparatus, as claimed in claim 2, wherein said fluid conveying means further includes:

a pressure providing system.

4. Apparatus, as claimed in claim 3, wherein said fluid conveying means further includes:

a return line from said pressure providing system to said reservoir.

5. Apparatus, as claimed in claim 1, wherein:

said outlets of said dispersion chambers are positioned in substantial contact with said applicator for applying dressing fluid directly to said applicator.

6. Apparatus, as claimed in claim 5, wherein:

said dispersion chambers are positioned longitudinally along an elongated bar which extends laterally across said carriage, said elongated bar having an upper surface.

7. Apparatus, as claimed in claim 6, wherein said fluid conveying means includes:

a manifold within said elongated bar;

a conduit interconnecting said reservoir and said manifold for conveying dressing fluid from said reservoir to said manifold; and

means interconnecting said manifold with each of said pulse valves for supplying dressing fluid to said pulse valves.

8. Apparatus, as claimed in claim 6, wherein:

said dispersion chambers are formed as laterally spaced hollowed out portions along said upper surface of said elongated bar; and

an elongated plate extends longitudinally across said upper surface of said elongated bar over said hollowed out portions and is attached to said elongated bar to form a cover for said dispersion chambers.

9. Apparatus, as claimed in claim 6, wherein:

a flat gasket, having an upper surface, a lower surface and a forward edge, extends longitudinally across said upper surface of said elongated bar with said lower surface thereof in intimate contact with said upper surface of said elongated bar, said gasket having laterally spaced cutout portions in said forward edge thereof forming said dispersion chambers; and

an elongated plate extends longitudinally across said upper surface of said gasket in intimate contact therewith to form a cover for said dispersion chambers.

10. Apparatus, as claimed in claim 9, wherein:

each of said dispersion chambers includes diffusion means for spreading the lane dressing across each of said dispersion chambers for even discharge from each of said respective outlet slits onto said applicator.

11. Apparatus, as claimed in claim 10, wherein said diffusion means includes:

a plurality of vertical baffles laterally spaced across said outlet slits of each of said dispersion chambers for spreading the lane dressing for even discharge from said respective outlet slits.

12. Apparatus, as claimed in claim 10, wherein said diffusion means includes:

a threaded rod extending laterally across said outlet slits of each of said dispersion chambers, the screw threads of said threaded rod forming vertical baffles for spreading the lane dressing for even discharge from said respective outlet slits.

13. Apparatus, as claimed in claim 12, further including:

a longitudinal groove along a bottom surface of said cover adjacent said outlet slits, said threaded rod being positioned within said groove.

14. Apparatus, as claimed in claim 10, wherein said diffusion means includes:

a barrier formed in said forward edge of said flat gasket between two of said outlets from adjacent ones of said respective pulse valves for spreading the lane dressing for even discharge from said respective outlet slits.

15. Apparatus, as claimed in claim 9, further including:

a recess formed along said upper surface of said elongated bar adjacent said outlet slits for catching the dressing fluid as it is discharged from said outlet slits, said applicator being positioned to pick up the dressing fluid from said recess and apply it to the bowling alley surface.

16. Apparatus, as claimed in claim 1, wherein:

said control means selectively varies the time of activation of each pulse valve to vary the amount of dressing fluid supplied to each dispersion chamber to vary the amount of dressing fluid applied to each zone.
